  • Patent number: 10622612
    Abstract: An electric propulsion vehicle has a high voltage electric drive system and a low voltage electrical accessory system. A high voltage battery pack provides electrical power at a relatively higher voltage for a traction motor. A low voltage distribution system is routed within the vehicle carrying a relatively lower voltage for the accessory system. A molded battery enclosure contains the battery pack and extends between predetermined locations in the vehicle body/frame. The low voltage distribution system includes a bus bar retained in the enclosure and electrically isolated from the battery pack. The bus bar has exposed terminal ends accessible at the predetermined locations. Incorporating the low voltage bus bar into the high voltage battery enclosure reduces the packaging space for the low voltage distribution system while simultaneously strengthening the enclosure.
