摘要： A refresh control system that selectively initiates a refresh charge cycle includes an energy storage device and an electric machine that is operable to charge the energy storage device. A control module monitors a usage period of the energy storage device and determines a bias factor. The control module determines a modified usage period threshold based on a usage period threshold and the bias factor. The control module regulates the electric machine to initiate a refresh charge cycle of the energy storage device when the usage period exceeds the modified usage period threshold.

摘要： A method and system to monitor a high voltage power relay operable to conduct electrical power from a source to a load, during each vehicle shutdown event. The system includes the electrical relay with a resistive device, electrically connected in parallel circuit, a controllable electrical load device, and a sensing device. A controller is connected to the electrical relay and each sensing device, and operable to identify a low electrical load condition at the load. The controller commands the load to operate at a known current draw level, commands the relay open, and monitors a change in power to the load device when the relay is commanded open. The electrical relay is functioning properly when the change in electrical power to the load exhibits a known profile over time, when the electrical relay is controlled to the commanded-open position.
