Breakthrough could lead to 732-mile electric car battery
A petrol or diesel engine is most efficient when running at a constant RPM.
If the engine were linked to a generator which constantly charged the battery & an electric motor was fed from the batteries.This might be a better way of doing things battery would never go flat because as soon as it went below a preset level the engine would start. The battery would give good acceleration & distance as always kept fully charged. If the driver went too fast or up many hills (regenerative braking as well) & took too much power the car would just reduce speed until battery charge level caught up. Drivers would understand its either very fast for short time or standard speed all the time. In emergency the constant RPM could be increased with override switch use very much more fuel & bring speed up to normal or charge battery very quickly losing any economy of driving . battery could also be charged from mains power when available. The best of both worlds. No new technology needed just rearranging it. If there were local power failures the vehicle could connect to external inverter be run stationary & power house or farm electrics.
