Vehicle lift apparatus and method

A jack assembly, comprising:

• a base member having a handle assembly extending therefrom, a remote control positioned in the handle assembly;
• a handle base section of the handle assembly that comprises a battery coupler and a control unit, the battery coupler configured to be selectively coupled to a rechargeable battery and the control unit configured to selectively direct power from the rechargeable battery;
• an electric motor coupled to the base member to selectively provide a torque to a gear assembly, the gear assembly coupled to a ball screw to selectively rotate the ball screw when the motor is powered;
• a carriage slidably coupled to the base member, the carriage having a lift nut coupled thereto, the ball screw threaded through the lift nut such that rotation of the ball screw moves the lift nut, and carriage, linearly along the base member;
• and
• a lifting arm pivotally coupled to the carriage on one end and pivotally coupled to a pivot arm at an intermediate location, the pivot arm further pivotally coupled to the base member at an opposing end;
• wherein, the control unit is configured to selectively power the electric motor to rotate the ball screw and transition the lifting arm between a raised and lowered position based on input from the remote control such that a distal end of the lifting arm travels along a substantially linear path of travel as the lifting arm transitions between the raised and lowered position.
