ABSTRACT:
In a control system for an electric powered vehicle of the type including a D.C. motor drivingly connected to roadway engaging drive wheels, there is provided an improvement. A control system for this type of vehicle has a controller for operating the D.C. drive motor with a voltage having a pre-selected magnitude, a first storage battery supported on the vehicle and having a charging mode and a discharging mode with a voltage rating during both of the modes being generally equal to the pre-selected magnitude, a circulation pump associated with the first storage battery for activating this battery, also driving the circulation pump during the discharge mode of the first storage battery. The improved control system in this type of an environment includes a second storage battery, a manually actuated starting switch for allowing the D.C. motor to be driven by the first storage battery, the second storage battery also driving the circulation pump for limited time after manual actuation of the starter. Also, the improved control system is useable when two pumps are associated with the first storage battery and then includes a control circuit for driving one pump selectively by the second storage battery and an enabling circuit for actuating the drive control by the second storage battery so that the vehicle responds to the second storage battery at least during initial operation.
