An agricultural/utility vehicle has as its motive power source one or more electric motors supplied by one or more rechargeable batteries to drivingly rotate a shaft of the vehicle driveline. To recharge the batteries, an external power source is applied to cause the driveline shaft to rotate, resulting in at least one of the electric motors acting as a generator to recharge the batteries. The external power source may include a source of fluid pressure that drives a hydraulic pump of the driveline as a hydraulic motor. The external power source may be an external source of rotational energy coupled to a power take-off shaft of the vehicle.
