ELECTRIC VEHICLE DEVELOPMENT CONTINUES

Improvements in batteries, electrical control, regenerative braking, weight reduction, and hybrid concepts which may lead to widespread acceptance of the electric vehicle are discussed. Increase of the ratio of battery weight to total weight, taking advantage of the mass compounding effect whereby the added structural weight of the vehicle increases at one half the added battery weight has been found to improve performance. Removal of peak currents from the battery and recovering braking energy have improved the vehicle range. A nickel cadimum battery in conjunction with the main lead system is advised, as well as a motor/generator/flywheel system for positive control of current flow. The components of a battery/flywheel propulsion system, and the chopper, or interupted control method are discussed, and electric vehicles developed by Toyota Motor are described.
