Vehicle battery-operated electric drive - uses parametric resonance regulated by semiconductor control to reduce energy losses

摘要

The battery-operated electric drive system for a vehicle uses a resonance pulsation motor supplied with current from the battery via a parametric generator. The braking energy is used for battery recharging and a flywheel is used for intermediate energy storage and to store kinetic energy e.g. so that in the case of a heavy vehicle it can be used to supplement the battery voltage when travelling up on incline. Pref. the generator controlled parametric resonance is obtained by semiconductor control. The system is designed to give reduced running costs since the thermodynamic losses are less, while the delivered mechanical output remains the same.
