       Electric Conversion Basics

  Removing and Replacing Components

#1. Welding and Steel Fabrication

The world was a different place fifty years ago. The thought of doing an electric conversion was entertaining back then. I have found that 75 percent of the conversion process of changing a gas car to electric is steel fabrication and welding. It can take years to become an experienced steel fabricator and thousands of dollars in welding and fabrication equipment. Steel fabrication is some thing that you are intrigued with and enjoy or you will never be good at it. Steel fabrication is an art and not a science. I started at ten soldering tubing together to make electric slot cars. I designed and fabricated my race cars for the NASCAR series and SCCA series. I still today in 2020 enjoy building electric vehicle concepts. Anyone can buy parts. You still have to put them together and install them in your vehicle. Electric Vehicle Concepts is still here to help with your electric vehicle build. This website is created to share my electric conversion history and hopefully educate the interested.

 

#1: Removing gas parts.

I have had people ask if they should remove the gas components before the car arrived. Knowing where the wires are going and coming from is easiest to see when they are attached to the components. Marking them well is a big time saver.

#2 Removing the structural steel.

Most of our modern cars are uni body steel structures. We have seen the change from frame and body cars to the uni body design of incorporating both the frame and body in one stamped part to save weight. Many designs use sub frames with the uni body design. This can speed up assembly. The front sub frame would carry the engine and transmission along with steering. The rear sub frame would carry the differential and rear suspension. Trunk areas are usually redesigned to carry batteries.

 

#3 Transmissions and gear boxes.

All vehicles use a transmission or gear reduction gear box. All gas and gas-electric (hybrids) use transmissions with a final drive gear box. Many hybrids use CVT's (Constant Velocity Transmissions). Many gas cars are using CVT's now.

Most full electric vehicle are direct connected to a gear reduction gear box or trans axle system. The electric motor can change the rotation direction electrically. No need for reverse gearing.

Electric conversion to a gas drive will need to fabricate and adapter plate to connect the transmission to the electric motor face. Also the flywheel or torque converter will need to be coupled to the electric motor shaft.

We have used automatics in the past. Manuals are good with a working clutch

New motor mounts will have to be fabricated along front battery box and mount for controller. Adapter plate on front of motor for AC compressor, power steering pump, alternator if you use it. Mount DC to DC converter. Mount charger and vacuum pump.

E-V Concepts has made over forty different styles of motor to transmission adapters and couplings. Canadian EV has some adapters. Call or email us if you cannot find one for your car.

#4 Wire your vehicle together.

      Electric Conversion Goals

Design Priorities - Parts and Manufactures

 

#1. Total System Voltage

You want the total running voltage as high as possible. 200 volts or more, up to 400 volts.

You are limited on space in most gas - electric conversions. You will use lithium ion batteries from a new EV. The higher the volts the less amps you use 
making the batteries run cool. Modern EVs run near 400 volts. Modern EVs are designed to use the complete floor for batteries. This is not the standard for gas converted cars. The front and rear are more common areas in gas conversions for batteries.

Out of the many electric conversions in the past fifty years. I find it hard to get over 300 volts using lithium batteries in gas-electric conversions. Less than 150 volts will barely push a 3000 pound vehicle at freeway speeds. The more battery capasity (Amps) the more range.

#2. Chargers.

 Your resting lithium ion cell is 3.7 volts times your total cells. The charger must shut off at the exact top of the charging voltage. Adjustable chargers are rare. Manzanita have been around for many years and will run up to 340 volts.

Elcon chargers can be programed by Elcon and small changes can be made in the car. Both will run 110 AC and 220 AC. Your choice of amps they put out. Nice feature Manzanity you can adjust the amperage out put.

#3. DC Controller or AC Inverter

Cost can have some decision on your choice of AC Drive or DC Drive.

AC Drives:

There are many choices under 150 volts for controllers or inverters.

AC Drives are usually more expensive. Especially over 150 volts. The Inverter is designed to work with the motor. These are bought as a motor - inverter kit.

DC Drives:

DC motor and controller choices are more available and can be bought from the manufacture separately. Netgain has been specializing in DC motors that can handle more than 150 volts.  There are more motor manufactures offering motor under 150 volts.

Soliton has some DC controllers that will go up to 340 volts. There are many DC controller manufactures offering controllers under 150 volts.

#4. Questions and answers.

Call or Email. Advise is free. I like to share my years of history and many testing failures. Saves you time and money.

The torque falls off above 3000 RPM's.
The smaller 9" motors rev higher and can run to 300 plus volts. $2500 
The Solitron DC controller will adjust to any voltage under 340 volts. $3000

The Manzanita Charger will adjust up to 340 volts. $3000 
You need an transmission adapter and motor coupling. $1500 Front adapter plate and pulleys may be needed for AC and power steering. $500

Need a proper fuel gauge Link Pro. $300

 

#5: Battery Choices

There are some mass produced batteries now.

The Fiat Samsung Bosch batteries come in factory package of 5 and 6 cell modules. The modules are the size of a group 23 lead battery. Ten pounds each. 20 volts each. Cost is $300 each. Ten would get you 200 volts. Higher is better. Return with any questions.

United States Electric Vehicle History          Electric conversion time line

     Lead acid / Nickel Metal Hydride / Lithium

 

In the 1970's we did not have digital cameras and computers to store photographs. Over this time many photographs were lost, destroyed or thrown out. Scanning fifty year old photographs doesn't look that great. This time line may be educational to some or boring to others. Can't say I remember half of it.

The basics of electric conversions are the same but the components have improved over the past fifty years. Many car models were repeated because they were good choices for electric conversions.

There are cars, tractors, boats and motorcycles. Concept designs and prototypes. Electric kit cars and vintage customs also in the mix.

In the 70's high volt DC drives were not readily available as they are today. Lead Acid batteries were it. Motors came from the fork lift industry and jet air plane starter motors. General Electric was the go to company with their DC motors and the EV1 controller.

                     1973
The EV-1 was one of the first DC high volt controllers available. Now we have controllers half the size that can handle the same amps.

                    1973
Very well used electric conversion. GE motor, Adapter and coupling I made connected to the Fiat transmission using the clutch. Fans for motor and controller.

There are many factors that will create changes in the performance of your electric conversion. Your vehicle choice and electric conversion components. You cannot see a magnetic flux field. You can calculate what you think your electric conversion kit will do. But in the end it is only the real seat of the pants experience that will give you the true experience and education.

There is a lot of electric conversion history in this website. There should be something for everyone.

Donor car choice for Lead Acid Battery powered Electric Conversions

The charger may be the most important choice in your electric conversion. It MUST shut off at the proper voltage. Lester chargers were one of the best in the 1970's. Voltage designed for 144 volts. 110 or 220 V ac input. Had a 12 Volt DC charger built into the same case. 144 volts was the goal. That is 24 - 6 volt batteries at 65 pounds each equals over 1500 pounds.

 

You are going to remove 500 pounds of gas components and add 1000 pounds. The small trucks were a popular choice in the early days. Not everyone wants a two passenger truck. Most people want a light vehicle that could carry four or five adults.

#1. You must be able to change the spring and shocks to carry the extra 1000 pounds.

#2. The bearings, brakes and suspension must be be strong enough to carry the extra weight.

 

My electric conversion car of choice in the 70's was the Italian made Fiats. The Fiats used the common 5" diameter coil spring and out board shocks. Most vehicles in the seventies used this design. I raced stock cars and had many extra springs and shocks that size. The over all steel was great. The manual transmissions were the best. I raced gas powered Fiats in the SCCA series also.

This is the reason you see so many Fiat's used in my electric conversions in my seventies.

         Lead-acid battery history

                 After the gas crises in 1972

In 1859, Gaston Planté invented the lead–acid battery, the first-ever battery that could be recharged by passing a reverse current through it.

Battery technology and availability has always made the biggest changes in electric vehicle transportation in the past past 100 plus years. When we did get a better battery technology than lead acid like the Large Format Nickel Metal hydride (NiMH) we had private interest like General Motors and Chevron Oil make sure the world would not use them.

 

It has been ugly and frustrating over the years trying to share the fun of electric propulsion. Since 2015 mass produced EVs with Lithium Ion Cells have arrived. You cannot convert a car for the price of a used mass produced electric vehicle from the major manufactures today.

      Nickel Metal Hydride history

     Here I thought I could make a difference in the world.    

                               How naive of me.

1990

General Motors purchased the patent from Ovonics in 1994. Stanford R. Ovshinsky was the one who invented and patented the NiMH battery and founded Ovonic Battery Company in 1982. By the late 1990s, NiMH batteries were being used successfully in many fully electric vehicles, such as the General Motors EV1, Dodge Caravan EPIC minivan, Solectria and Toyota RAV4-EV. Field tests indicated the Ovonics battery extended the EV1′s range to over 150 miles and Solectria Sunrise achieved 375 miles on a single charge back in 1996.

In October 2000, GM sold the patent to Texaco and a week later Texaco was acquired by Chevron. Chevron’s Cobasys subsidiary that now has the rights to sell the NiMH batteries will in theory only provide these batteries to large OEM orders of 10,000+. 

 

Afterwards General Motors shut down production of their electric car production (the EV1) citing lack of battery availability as one of their chief obstacles.

Cobasys/Chevron has effectively blocked the use of NiMH batteries by start-up EV manufacturers and has the ability to keep doing so until 2014 when the patents expire.

It’s interesting to note that in 1997-2003 Toyota sold/leased 1485 RAV4 EVs in California that used large format NiMH batteries produced by Panasonic, which were patent licensed Ovanics technology.

“The original batteries found in the remaining 750 RAV4 EVs that weren’t crushed like GM’s EV1s are still on the road today and have proven the longevity and usefulness of large format NiMH batteries.”

 

Toyota discontinued producing the RAV4-EV because Chevron sued and won a $30 million USD settlement from Toyota-Panasonic from the International Court of Arbitration which forced them to shut down their production line for large NiMH batteries.

 

In addition California’s Air Resources Board (CARB) caved to the pressure of the US federal government and eliminated most of their Zero Emissions Vehicle (ZEV) requirements, which was the main reason Toyota had produced the RAV4 EV in the first place.

Noteworthy is that in July 2009, Cobasys NiMH division (Chevron-Texaco), was sold to a Bosch and Sanyo consortium, but they still retained the patent rights and collect royalties on the batteries.

General Motors and the US Auto Battery Consortium

According to Ovshinsky, the American auto manufactures falsely suggested that NiMH technology was not yet ready for widespread use in road cars. Members of the USABC, including General Motors, Ford, and Chrysler, threatened to take legal action against Ovshinsky if he continued to promote NiMH's potential for use in BEVs, and if he continued to lend test batteries to Solectria, a start-up electric vehicle maker that was not part of the USABC.

 

Critics argue that the Big Three were more interested in convincing CARB members that electric vehicles were not technologically and commercially viable.

In 1994, General Motors acquired a controlling interest in Ovonics's battery development and manufacture, including patents controlling the manufacture of large NiMH batteries.

The generator sat over the electric motor. Using the Curtis DC controller at 150 volts. The batteries and charger were in the small trunk area. The generator could charge the batteries while driving or stopped.

Ford manual transmission with working clutch connected to the DC 9" motor. The Honda EU 6500 generator are double insulated and very quiet. With electric start and choke we moved controls to the interior of the car.

                 1972

First Electric Conversion

1969 124 Fiat Sport Coupe. Used the Fiats for many electric conversions and kit car donors in the 70's.

                      1973
First fiberglass design concept in 1973. Body put over a 1969 Fiat 124 Sport Coupe electric conversion. Hard top roof was removed and soft top made. First and last time for cutting the top off a car to make a convertible.

1974

         1970 Fiat 124 Spider

Bought my first Fiat 124 Spider in 1972. Later raced them in the SCCA national series for a few years.

                    1975
Another Berlinetta fiberglass body over a 1969 Fiat 124 Spider

electric conversion. Wheels and tires from my NASCAR racer.

1976

1974 Fiat 130 Salon

electric conversion. This model was never sold in the USA. Fiat sent six of these 130's along with forty other vehicles for crash testing in the USA. I was able to get a couple. Bent front bumper from a 5 mile a hour crash test.

                     1977

The 1969 SL Mercedes was a good start for the early electric conversions. They were inexpensive back then. Could carry the weight of the lead batteries.

                     1978

Still running lead acid batteries. The older 1966 Mustangs were plentiful and cheap. Easy to change the suspension for the extra battery weight.

                     1979

The old hot rods were a simple toy for city use. A lot of show but not much go with lead batteries.

                     1980

Another electric kit car from our Berlanetta molds. Triumph TR7 donor chassis. A lot of extra work to make battery boxes to carry lead acid batteries.

                     1981

This was a good choice for electric conversion 1903 carriage for park tours.

                     1982

The early 1968's Jaguars were built to carry the big engines. Plenty of space and could carry the weight. Aerodynamics helped a lot.

                     1983

Early Ferrari look alike called the Kelmark. Could be put on a number of chassis. Well done for the early kit cars.

                     1984

The older 1958 MK1 Jaguar. Real luxury for it's time. Could not find many people in the USA to maintain or get parts. They are expensive cars now.

                     1985

Early iron from the 1930s was solid and strong. Easy to work with and could carry the weight. Always used steel wheels.

                     1986

Early Ferrari GTO look a like replica used the 240Z Nissan. There were some interesting kit cars in those days.

                     1987

Early Ford GT40 look alike called the Avenger created by Fiberfab. Always liked the kit cars. This used the Mustang 11 suspension.

                     1988

Early Ferrari look alike called the Daytona. This was a limited  production made by Bernie Mac. Was sued by Ferrari for his copies.

                     1989

This was the beginning of the A123 26650 spiral lithium cells used in the Dewalt portable power tools.

We designed a futuristic 1932 lowboy coupe, Rixter Roadster.

                    1990

With the new light weight 26650 lithium spiral cells we could now use donor vehicles for electric conversions that could not carry the heavy lead acid batteries. 

MGB 1972

                    1991

1953 Mercedes Gazelle kit car. Built on the Ford Mustang suspension and sub frames . Ford transmission and rear end. Hybrid design with the Honda EU 3500 generator mounted over the  motor.

The original intent of the equity alliance was to develop NiMH batteries for GM's EV1 BEV. Sales of GM-Ovonics batteries were later taken over by GM manager and critic of CARB John Williams, leading Ovshinsky to wonder whether his decision to sell to GM had been naive.

 

The EV1 program was shut down by GM before the new NiMH battery could be commercialized, despite field tests that indicated the Ovonics battery extended the EV1's range to over 150 miles.

The second generation EV1 (and those released by Honda, Toyota, and others) from 1998 to the end of the program, featured nickel-metal-hydride or even lithium-ion (Nissan) batteries with a range of 100 or more miles.

The film (Who killed the electric car) documents that the company which had supplied batteries for EV1, Ovonics, had been suppressed from announcing improved batteries, with double the range, lest CARB be convinced that batteries were improving.

                    1992

Commissioned by a Brazilian biodiesel manufacture wanting to produce electric vehicles for international sales. The Sigma GTE. Created the body from their conceptual drawings. AWD Twin motors designed by E-V Concepts.

                    1993

Mazda Miata electric conversion. Since there were no more Fiat 124 Spiders. The Miata was a direct copy of the Fiat. Good transmissions. Nice small convertible EV.

 With little space in the VW  we decided to use a Honda EU1800 generator for a hybrid design. The generator could run during driving or stopped. Electric on/off start switch was moved inside.

 This was the start of the Winston (ThunderSky) LiPo4 lithium cells. We had enough space to get over 150 volts using 100 amp cells. Anything was better than lead.

                    1994

1964 VW beetle. We would not convert the VW's and Porsche's with lead acid batteries. They could not handle the weight. It was to difficult to beef up the old style suspension.

Later, General Motors sold the supplier's of the NiMH patents the majority controlling shares to the Chevron Corporation and Cobasys to make sure no auto manufacture in the world would produce the batteries in electric vehicles.

As part of the not-guilty verdict, the famed engineer Alan Cocconi explains that with laptop computer lithium ion batteries, the EV1 could have been upgraded to a range of 300 miles per charge. He makes this point in front of his T-Zero prototype, the car that inspired the Tesla Roadster in (2008).

 

The original Tesla Roadster (Lotus) was designed by AC Propulsion in California.

 

The second generation EV1 (and those released by Honda, Toyota, and others) from 1998 to the end of the program, featured nickel metal hydride or even lithium-ion (Nissan) batteries with a range of 100 or more miles.

The film (Who killed the electric car) documents that the company which had supplied batteries for EV1, Ovonics, had been suppressed by General motors and Chevron Oil from announcing Ovonics improved batteries with double the range. General Motors and Chevron did not want CARB (California Air Research Board) to be convinced that batteries were improving.

 We still like to carry a new 50 foot charge cord. There were no charging stations or J1772 plugs. The alternator was used as the regeneration for the 12 volt battery during braking.

      The small trucks had full steel frames and the heavier suspension to carry the extra 1000 pounds of lead batteries. We could carry a generator. The lead batteries would overheat if you worked them to hard.

                    1995

The Sigma GTE body was used on a number of donor chassis's. The Mitsubishi Eclipse was a favorite of mine. Hardtop or convertible.

                    1996

The Brazilian company wanted a motorcycle. Their conceptual body was designed by an Israeli digital engineer. He considered it to be a Ferrari design concept. We made the real thing electric.

                    1997

1958 corvette electric kit car.

used Camaro sub frames and suspension. Chevy transmission and rear end

                    1998

1990 Chevy S10 truck

The early small trucks were very poplar electric lead battery conversions. The Nissan"s trucks were available in the 1960's.

 Originally we used smaller lead acid batteries to get the voltage up higher with the limited space we had. Ten years latter we put lithium batteries in for a new owner.

We connected an eleven inch electric motor to the factory transmission with a working clutch. Used a high powered Zilla DC controller and Mazanita charger in the front.

                    1999

   959 Porsche fiberglass kit car body on a 911 Porsche.

This was the last lead acid electric conversion. The owner did not want to spend the extra money it cost for lipo4 lithium batteries.

2000

In real world use, some fleet Toyota RAV4 EVs, using Nickel metal hydride batteries, have exceeded 100,000 miles (160,000 km) with little degradation in their daily range.

From a Southern California Edison (SCE) assessment:

SCE’s positive experience points to the very strong likelihood of a 130,000 to 150,000-mile (240,000 km) Nickel Metal Hydride battery and drive-train operational life.

                    2000

A 1937 Ford fiberglass kit car

Used Ford Mustang suspension.  Conversion using the 26650 A123 lithium spiral cells .

EVs can therefore match or exceed the lifecycle miles of comparable internal combustion engine vehicles.

Lithium batteries are perishable to some degree; they lose some of their maximum storage capacity per year even if they are not used. Nickel metal hydride batteries lose much less capacity and are cheaper for the storage capacity they give, but have a lower total capacity initially for the same weight.

                    2001

         550 Spider Kit Car

Convertible electric Conversion

With the light weight batteries the VW suspension could be used. We made a tube frame to match the original factory tube frame with all original VW suspension.

Soliton DC controller with Manzanita charger behind the front seat. All lithium LiPO4 batteries in the trunk.

 Front wheel drive. The electric motor seemed just a bit longer than the gas engine. Was a tight fit with the AC and power steering pump on the front.

                    2002

  Audi TT Convertible Conversion

We had never done this model Audi. I think this was one of the best choices for electric conversion with lithium batteries.

 

Hybrid Drive technology history

 Ferdinand Porsche was one of the originals to combine the gas and electric motor for propulsion in the 1800's. E-V Concepts hybrid propulsion systems have worked well for over 25 years and hybrid designs are now being used by all other auto manufactures.

                    2003

Electric kit car conversions

company wants a motorcycle. Their conceptual body was designed by an Israeli digital engineer. He considered it to be a Ferrari design

                    2004

      Porsche Boxster 2000

AC compressor and power steering pump on the front. Used the factory front motor mount along with the rear motor mounts.

                    2004

       Porsche Boxster 2000

Made the rear battery box go around the transmission. Had batteries in the front trunk area.  And a few more in the engine bay.

                    2004

       Porsche Boxster 2000

These early Boxsters had engine oiling problems. The electric conversion cost the same as a Porsche gas engine replacement.

                    2005

Mercedes SL 500 1999

       Mercedes SL 500 2000

 

Told the client to find something he liked and would want to keep.

This was a pretty choice.

 

In the early 1970's the V twin Harley Davidson was the ideal small engine for E-V Concepts hybrid designs. The large displacement V-twin made good torque at low speeds and matched the running speeds of our electric motors. The V-twin gas engine was inline with the electric motor and coupled by an electric clutch much like the magnetic clutch on your automotive air conditioning compressor.

                    2006

    Ford Shelby Cobra kit car

Still one of the most popular  replica kit cars. A good number of companies made replica bodies.

You can always find kit car projects that people gave up on completing.

                    2007

              Mazda RX8

Front battery box went across the front where the radiator and AC condenser would have been. Put the factory engine cover back on.

                    2007

              Mazda RX8

This car was going into colder area of the USA. We built hot water boxes under the front and rear battery boxes. Electric heater could run during charging or driving.

                    2007

          2004 Mazda RX8

The Rotary Wankel engine could have engine trouble if not taken care of.  Nice looking car and could get them with low miles and a bad engine.

                    2008

         2000 Ford Mustang

This was a little heavy for a lithium electric conversion. But this was the clients choice. Nice looking and inexpensive for the time.

Electric Vehicle Concepts combines the best of both worlds.

With the flip of a switch your gas engine is turning with the electric motor and drive train. The rotating mass of the electric motor helped increase the fuel efficiency of the gas engine at freeway speeds. It was now possible for the electric motor to generate power to recharge the battery supply.

 

The hybrid plug-in electric vehicle with a battery pack that can travel over 100 miles per charge and the ability to switch to the hybrid mode and use the gas or diesel engine when desired. Using an internal combustion engine to charge the batteries or propel the vehicle. E-V Concepts hybrids can have unlimited driving range with the advantages of a pure electric vehicle. The use of a small engine and electric motor at constant freeway speeds creates good efficiency.

Facade Electric Vehicle Concept

This was the only four door E-V Concept we designed. This was done for a new EV company. The original donor was the Dodge Intrepid. Later the Honda hybrid.

 

Lithium and lithium-ion batteries

 

 

Lithium is the metal with lowest density and with the greatest electrochemical potential and energy-to-weight ratio. The low atomic weight and small size of its ions also speeds its diffusion, suggesting that it would make an ideal material for batteries.

 

Experimentation with lithium batteries began in 1912 under G.N. Lewis, but commercial lithium batteries did not come to market until the 1970s. Three volt lithium primary cells such as the CR123A type in 1990 and three volt button cells are still widely used, especially in cameras and very small devices.

This led a research team managed by Akira Yoshino of Asahi Chemical, Japan, to build the first lithium-ion battery prototype in 1985, a rechargeable and more stable version of the lithium battery; Sony commercialized the lithium-ion battery in 1991.

In 1997, the lithium polymer battery was released by Sony and Asahi Kasei. These batteries hold their electrolyte in a solid polymer composite instead of in a liquid solvent, and the electrodes and separators are laminated to each other. The latter difference allows the battery to be encased in a flexible wrapping instead of in a rigid metal casing, which means such batteries can be specifically shaped to fit a particular device.

 

This advantage has favored lithium polymer batteries in the design of portable electronic devices such as mobile phones and personal digital assistants, and of radio-controlled aircraft, as such batteries allow for more flexible and compact design. They generally have a lower energy density than normal lithium-ion batteries.

In 2019, John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino, were awarded the Nobel Prize in Chemistry 2019, for their development of lithium-ion batteries.

Another Sigma GTE Electric kit car

Conversion. Changing the donor car gave it a unique look. Manufacture choice was a client option along with other body modifications.

                    2013

       Mamba  electric kit car
Design by another upstart EV company. We took they conceptual drawings and created the full size sculpture (plug) for a fiberglass molds. The Mitsubishi Eclipse was used for the donor. Hardtop or convertible.

                    2014

          e-venton kit car

One of the few times tried to make a replica. The Lamborghini Reventon was a limited build of 21 cars. A client requested we build him an electric replica of this million dollar supercar.

The chief knock on electric vehicles has always been that they don't have enough range for the general public. With the advent of the lithium batteries used in our cell phones and laptops we can create a battery pack with over a 200 mile range.

In 2009, President Barack Obama announced 48 new advanced battery and electric drive projects that would receive US$2.4 billion in funding under the American Recovery and Reinvestment Act. The government claimed that these projects would accelerate the development of U.S. manufacturing capacity for batteries and electric drive components as well as the deployment of electric drive vehicles, helping to establish American leadership in creating the next generation of advanced vehicles.

Out of these grants 300 million was given to the bankrupt Tesla motor company. Only one year latter the Tesla motor company went bankrupt again.

                    2015

        Gallardo  kit car

Another replica of the Lamborghini Gallardo. The Toyota Celica was the donor car with electric conversion. The electric motors sat very low compared to the gas engine.

                    2016

         Yacht Conversions

The Entra Coastal Canal runs from New York to Florida and travels threw Charleston port.

The announcement marked the single largest investment in advanced battery technology for hybrid and electric-drive vehicles ever made. Industry officials expected that this US$2.4 billion investment, coupled with another US$2.4 billion in cost share from the award winners, would result directly in the creation tens of thousands of manufacturing jobs in the U.S. battery and auto industries.

The awards cover US$1.5 billion in grants to United States-based manufacturers to produce batteries and their components and to expand battery recycling capacity.

U.S. Vice President Joe Biden announced in Detroit over US$1 billion in grants to companies and universities based in Michigan. Reflecting the state's leadership in clean energy manufacturing, Michigan companies and institutions received the largest share of grant funding of any state. Two companies, A123 Systems and Johnson Controls, would receive a total of approximately US$550 million to establish a manufacturing base in the state for advanced batteries, and two others, Compact Power and Dow Kokam, would receive a total of over US$300 million for manufacturing battery cells and materials.
