Claim Text:
1. A rechargeable high-voltage battery pack, comprising: a plurality of series-coupled energy storage elements; an interlock having a first node and a second node, said first node coupled to said plurality of series-coupled energy storage elements with said interlock responsive to a control signal to control a power communication of said first node to said second node, said interlock enabling said communication with said control signal in a first mode and said interlock disabling said power communication with said control signal in a second mode; a housing enclosing and sealing said plurality of series-coupled energy storage elements and said interlock with a plurality of exterior walls; an operational port coupled to a portion of a first particular one exterior wall of said plurality of exterior walls, said operational port coupled to said second node and providing a first energy transfer with respect to said plurality of series-coupled energy storage elements only when said power communication is enabled; and a service port coupled to a portion of a second particular one exterior wall of said plurality of exterior walls, said service port coupled to said first node and providing a second energy transfer with respect to said plurality of series-coupled energy storage elements without regard to whether said power communication is enabled; wherein said service port includes an energy transfer direction control limiting said second energy transfer to a single direction, and wherein said single direction discharges said a plurality of series-coupled energy storage elements through said service port.
