Abstract

A power unit (1) for supplying power to a variety of interchangeable external equipment includes a battery (10) for storing the power, electrical input and output connectors and control systems (13, 14) for charging the battery (10) and supplying electrical power from the battery (10) to the external equipment, and an output shaft (21) driven by a motor (20) powered by the battery (10) for supplying shaft power to the external equipment. A motor control system (30) controls operation of the motor (20) responsive to control signals (32) received from the external equipment via a control signal connector. The control system (30) may emulate the controller of an internal combustion engine, and the power unit (1) may include an output shaft mount (40) corresponding to an SAE standard flywheel housing, so that the power unit (1) may be used as a direct replacement for a conventional power unit having an internal combustion engine.
