Patent number: 10155449Abstract: A battery power integration apparatus includes a power converter, a battery control module, and a relay. The power converter has an input side and an output side, and the input side is connected to a high-voltage DC voltage. The battery control module includes a relay control circuit and a pre-charge control circuit. The relay is connected to the input side of the power converter and the battery control module. The pre-charge control circuit receives a pre-charge enable signal generated from the power converter to pre-charge the input side of the power converter. The power converter steps down the high-voltage DC voltage to output a low-voltage DC voltage at the output side thereof when the relay control circuit turns on the relay, thus supplying the required power for low-voltage devices inside a hybrid electric vehicle.Type: GrantFiled: November 20, 2015Date of Patent: December 18, 2018Assignee: DELTA ELECTRONICS, INC.Inventors: Chin-Hou Chen, Wen-Sheng Tsao, Chen-Bin Huang, Jui-Teng Chan
