Abstract

Abstract A wheeled vehicle is provided including a main frame having a plurality of ground engageable support wheels. An electric motor is supported from the main frame and drive train structure drivingly connects the rotatable output shaft of the motor to at least one of the ground engaging support wheels. A bank of rechargeable storage batteries is also supported from the main frame and electrically connected to the motor for actuation thereof through a variable voltage control. Also, a pair of generators or alternators are supported from the main frame and are driven from at least one of the ground engaging support wheels of the vehicle. The generators or alternators are electrically connected to the bank of storage batteries for recharging the latter. At least one of the generators is electrically connected to the bank of storage batteries through a voltage regulator and the circuit electrically connecting the other generator or alternator to the bank of storage batteries may include a control switch actuated to a closed position upon initial depression of the brake pedal of the associated vehicle. It is intended that the generators or alternators will be used to partially recharge the bank of batteries when the vehicle is coasting to a stop or coasting downhill.
