Because of growing concern over pollution from exhaust gases, and the development of advanced batteries giving better performance and longer range, there is renewed interest in electric propulsion. The paper describes a typical electric drive system comprising battery, controller, and motor, and relates experience in a trial programme with several hundred vehicles worldwide. The development of sodium sulphur battery technology is then outlined and the current status is presented. Comparisons between lead acid and sodium sulphur batteries show that the four-times-greater energy density of sodium sulphur cells can improve vehicle range to very acceptable levels.
