Integrated high voltage service disconnect for traction batteries

摘要

A traction battery includes a battery housing having a tray and a cover cooperating to define an interior. A plurality of battery cells are arranged in an array and disposed on the tray within the interior. A service disconnect base is disposed on an exterior surface of the housing and includes a uni-terminal connector having a receptacle disposed within the base and electrically connected to the battery cells. A service disconnect plug is integrally incorporated with a single high voltage cable that is partially disposed in the plug. The service disconnect plug includes a body configured to mechanically engage the base and a prong mechanically connected to the high voltage cable and configured to be received within the receptacle to create an electrical connection between the battery cells and a high voltage bus when the body is engaged with the base. The plug may include a cover portion that enclosures a terminal disposed on the housing.
