HIGH-ENERGY BATTERY FOR ELECTRIC ROAD VEHICLES

Brown Boveri have developed a sodium-sulfur battery designed to give a medium-sized saloon car a range of 150 to 250 km, acceleration from 0 to 50 km/h in 7 s and a cruising speed of 120 km/h. The battery has a storage capacity of 32 kWh (2 h rate), a maximum output of 50 kW and an energy density of 120 Wh/kg. Details are given of the electrical and mechanical design of the battery, maintenance of operating temperature, charging arrangements, and the design of the main associated components: drive motor, transmission and power controller. The particular advantages of an electric over a conventional car are regarded as reduced air pollution, less noise and lower energy costs, as shown by a comparative analaysis of the two vehicle types. It is anticipated that series production of battery-driven cars will begin in the 1990s.
