Abstract
A device and system that can dynamically provide variable load on a generator and intelligently distribute generated power to loads and energy storage devices is disclosed. One system includes load profile controllers that employ a switching strategy to dynamically vary the load the generator induces while producing regenerative energy. This switching strategy may allow for a wide dynamic range of configurable damping characteristics, as well as decouple generator damping and the system output power. Multiple load profile controllers can be used together via a communications network, such as a vehicle controller area network (CAN) bus. A central regeneration controller or existing electronic control unit (ECU) can issue commands to change damping performance in different load profile controllers. By networking multiple load profile controllers together in either a distributed or centralized manner, the system may allow for intelligent power routing, coordination of multiple energy-generating devices (such as regenerative shocks and brakes), and improved utilization of on-board energy storage devices.
