摘要： An energy system for heavy equipment having an actuator for operating a tool includes a bus, an engine, a generator, an energy storage device, and a controller. The bus is for providing electricity to the actuator as a function of operation of the tool. The engine is for providing a power output and the generator is coupled to the engine and configured to provide electricity to the bus. The energy storage device is configured to receive electricity from the bus for storage of energy, and is further configured to provide electricity to the bus to supplement the electricity provided by the generator. The controller is configured to change the power output of the engine as a function of electrical demand on the bus. In response to a change in the electrical demand, the controller is configured to change the power output of the engine at a rate that is less than a maximum capability of the engine.
