The electric car past, present and future

 

The Past

Electric vehicles were reported to start back in 1832 when the first crude electric carriage was born! Thatís nearly 176 years ago. Then followed a range of more practical vehicles using better batteries which paved the way. France and Britain were the first nations to support the widespread development of the electric vehicle. Over a hundred years ago, an electric vehicle, the Jamais Contente, held the world land speed record when it achieved over 100km/h! The first commercial application was established as a fleet of New York City taxis built by the Electric Carriage and Wagon Company of Philadelphia. At this time, cars were available in many forms - steam power - electric power and gasoline.

The decline of the electric car was brought about by several interesting developments. Ironically it was the invention of the electric starter motor for the combustion engine by Charles Kettering in 1912 which made gasoline cars even more acceptable and therefore they flooded the market. It required great caution to start up gas burning cars using a cranking handle. The crank handle was responsible for many a broken wrist! The real nail in the coffin was the invention of automotive Mass Production in 1912, one year after the Baker electric passenger car was released.

The re-emergence of the electric car was facilitated as far back as 1947 by the invention of the first transistor in the Bell Laboratories, USA, by Walter Brattain. In 1954 Texas Instruments introduced the silicon transistor making it possible to fit the technology on a single slab of silicon, leading to the integrated circuit that eventually made the electric carís motor speed controller possible.

As transistor technology has been refined and compacted tremendous practical  progress was achieved in electronics and electric cars started to make a comeback. Over time electric cars have been continuously improved, but only recently modern computer aided equipment  has been available to make complex shapes cost effectively, from lightweight and stronger materials. With a greater understanding of thermal dynamics and material science, the electric motor has come a very long way. Some of the issues associated with older electric vehicles were with motor reliability and old fashioned DC brushed motors which were incorrectly made and matched to applications, caused overheating and eventually component failure.

The present

After several years of research and development activity looking at advanced electric motors, control systems and the evaluation of high energy automotive batteries, Green MotorSport (GMS) will shortly be supplying an entirely new and highly efficient drive train for electric vehicles. The new GMS drive train is based around the brand new liquid cooled GMS M1 motor, which was specially designed to give outstanding performance when used in lightweight vehicles.

The GMS electric motor is not a modification of any other motor, but it has been completely researched and designed from the ground up, by our technical partners. The design has been evaluated and engineered so that GMS can offer a very cost effective and competitive electric power train for vehicle conversions, as well as for OEM manufacturers interested in building electric cars. The technology has been designed to minimise the material and fabrication costs of electric motor components. This ensures that the package that Green MotorSport offers is true value for money.

At the heart of this electric car package there is also a high-powered controller, which is matched to the individual motor and is pre-programmed to deliver exceptional performance. Two motors are used within the protected gearing design configuration to deliver a cost effective, energy efficient drive system. This unique drive configuration gives direct drive to each wheel on the axle with programmable limited slip capability.

Battery Research and development

Green MotorSport has been researching new battery technologies for some time now and speaking with major manufacturing organisations in order to find the most cost effective, viable battery solution for electric cars. There have recently been rapid advances in battery chemistry with certain technologies reaching an amazing 300 Watt hours per KG or more, compared with the 85-155 Watt hours per KG from the various lithium ion technologies currently available on the market.

Building the vehicle you want

After much engineering, testing and researching we have designed and built a cost effective power train which is now available to customers. Bearing in mind that the average journey length of the two and a half million new fossil fuel powered cars sold in the UK every year is only about 10 to 12 miles and a third of households have more than one car, an electric vehicle would make the ideal second car for use on shopping and school trips etc.  Below the "GMS Dual Powertrain"

New materials for the automotive Industry

Currently Green MotorSport is evaluating several interesting new materials for use in the automotive industry for various components, from non structural areas, to key load bearing structures. These new materials could replace existing chassis materials that are not so cost effective and environmental friendly. The development process of these materials is very interesting, and there is scope for cost effective mass production.

Changed attitudes in America

Over the last 6 months we have had tremendous interest from the US. People in the States are waking up to the benefits of electric vehicles and the cost implications of running a family car as the price of fuel rises. People donít want to rely on fossil fuels any more, and many organisations in different states are seeking alternative power train solutions for electric conversions on existing cars. Many large companies are now looking at green transportation technologies with a view to reducing emissions and the impact on our world. Cars like the Tesla are emerging into the automotive marketplace. Cars that are fast and sporty enhance the image of the electric car, but the truth is that emissions reduction on a level that is required to stabilise the climate can only be achieved with huge changes throughout the whole global population. This can only be achieved by balancing our carbon emissions globally, as well as directly replacing fossil fuel consuming devices.

We are showing people that green is not only cool, fast and fun, but also economic. Currently electric propulsion systems are expensive, but GMS power train is about to change that. Our simple, cost effective design will go into virtually any car under 1800KG, and provide good performance.
