ELECTRIC CARS ADVANCE IN THE US

The article describes the development of a new advanced electric car called the ETV-1, produced under contract to the US Department of Energy, as part of the electric and hybrid vehicle program. UK development of electric vehicles, concentrated mainly on short-range delivery vehicles, is contrasted with that of the United States. The basic problems of the electric vehicle are examined. It costs as much as a petrol-driven one to run but has an inferior performance, it does not save energy but it does save oil. A new lightweight 20 horsepower DC traction motor has been developed for the ETV-1, which is equipped with a regenerative braking system. When the brakes are applied, or the car travels downhill, the motor acts as a generator helping to recharge the batteries. A microprocessor is used to control the energy flow through the propulsion system. High energy density lead-acid batteries providing 38 watt hr per kg with a 500 cycle life have been developed. It is hoped that the styling, performance and relatively low initial and operating costs will make the ETV-1 attractive as an in-town second car with mass production possible in the mid-1980's.
