| Abstract: | Several key technologies of Battery Management System （BMS） for a Hybrid Electric Vehicle （HEV） are presented, including high voltage management, high precision parameters sampling and the estimated algorithm of State of Charge （SOC）. The serviceability and validity of the BMS are proved by a series of bench tests. The results indicate that the high voltage safety of the system conforms to the Hybrid Electric Vehicles Safety Specification, and that the accuracy of both parameters sampling and SOC estimation meets the requirements of a HEV Battery Management System. |
