Abstract
A service cart for an electric vehicle (EV) battery, comprising a lift assembly supporting a platform. The platform is configured to support the EV battery. The service cart comprises an electrically-driven hydraulic pump that is configured to extend and retract the lift assembly in order to raise and lower the platform. The service cart may comprise one or more electric wheels which may be driven by rotational force from a first electric motor, or controlled with respect to an adjustable directionality by a second electric motor.

A service cart configured to support an electric vehicle battery comprising:
- a support frame;
- a plurality of wheels coupled to the support frame, each of the wheels having an adjustable directionality with respect to the support frame;
- a lift assembly supported by the support frame at a proximal end of the lift assembly;
- a platform supported by the lift assembly and arranged at a distal end of the lift assembly, the platform configured to support the electric vehicle battery;
- an electrically-driven hydraulic pump interfacing with the lift assembly, the electrically-driven hydraulic pump operable to raise and lower the platform by extending and retracting the lift assembly respectively;
- and
- a handle coupled to the support frame,
- wherein
- the handle further comprises electric controls configured to control the electrically-driven hydraulic pump.
