An electric drive motor drives the vehicle and is powered from a bank of drive battery packs. An electric recharge motor drives a plurality of generators to recharge all of the batteries. The recharge motor is powered from a bank of recharge battery packs. Drive battery packs are paired together with recharge battery packs. A timer switch opens and closes electrical contact between each pair of battery packs and its corresponding electric motor, one pair at a time. Thus, a drive battery pack powers the electric drive motor while a recharge battery pack powers the electric recharge motor. Non-connected battery packs are recharged by the plurality of generators. The timer switch sequentially switches through all pairs of battery packs in such a fashion that each pair of battery packs is recharged for a longer period of time than it is discharged.Field of SearchBATTERY-FED MOTOR SYSTEMSGENERATOR-FED MOTOR SYSTEMS HAVING GENERATOR CONTROL With plural, diverse or diversely controlled generators With flywheel on generator or on motor Control of both the generator and the circuit to the motor With motor control Control of both the generator and the motor | |
