Abstract
A battery pack for a vehicle electrical system configured with high-voltage bus bars. A positive bus bar and a negative bus bar may provide power generated by the battery pack to a drive module of the vehicle, to power one or more components of the vehicle. The drive module may additionally couple to high-voltage positive and negative bus bars. The high-voltage bus bars may be configured to provide additional power to the drive module from another battery pack, such as via a battery balance box. Additionally, the high-voltage bus bars may be configured to carry excess power from the drive module to another drive module associated with the vehicle via the battery balance box. The high-voltage bus bars may be configured to de-energize in the event of a thermal runaway or other failure of a battery module of the associated battery pack.
