Claim 15:
16. An electrically powered work vehicle, comprising:
a work vehicle frame;
a plurality of ground engaging units for supporting the work vehicle frame from a ground surface, at least one of the ground engaging units being powered by an electric drive motor to drive the vehicle;
an electrical power storage system carried by the work vehicle frame and connected to the electric drive motor to provide electrical power to the electric drive motor;
a work tool coupler carried by the work vehicle and configured to selectively interconnect the work vehicle with a coupler receiver of a selected one of a plurality of different work tools;
a vehicle side electrical connector carried by the work tool coupler and configured to transfer electrical power to the electrical power storage system to charge the electrical power storage system; and
an electrically powered hydraulic power supply configured to provide hydraulic power to hydraulic components of the work vehicle, the hydraulic power supply including vehicle side hydraulic fluid supply and return connections such that hydraulic power can also be provided to a work tool or other device;
wherein the electrically powered hydraulic power supply further comprises a tank configured to provide a reservoir of hydraulic fluid, an electrically powered hydraulic pump including a pump inlet and a pump outlet, an intake passage connecting the tank to the pump inlet, a supply passage connecting the pump outlet to the hydraulic components and to the vehicle side hydraulic fluid supply connection, a return passage connecting the tank to the hydraulic components and to the vehicle side hydraulic fluid return connection, and a heat exchanger disposed in the return passage so that hydraulic fluid returning from the vehicle side hydraulic fluid return connection to the tank passes through the heat exchanger and is cooled by the heat exchanger.
