    摘要： An apparatus and method efficiently integrating inductive and conductive charging systems, including embodiments directed towards enabling user selection of either, or both, of conductive and inductive charging. Conductive charging and inductive charging both have, in certain contexts or when judged by different criteria, advantages over the other. Systems and methods relying on one or the other would not have as wide-spread value to a user with opportunities to access both types of charging modalities.

    摘要： A system for integrating the venting feature of a battery with a means for simultaneously disconnecting the cell from the battery pack, thereby isolating the cell, is provided. The provided battery interconnect system is comprised of a battery, a connector plate for electrically coupling the battery to a battery pack, and an interruptible electrical connector for electrically coupling the connector plate to a battery terminal vent. The venting region, defined by scoring on the battery terminal, ruptures when the internal battery pressure exceeds the predefined battery operating range, causing the interruptible electrical connector to break and disrupt electrical continuity between the connector plate and the battery terminal.
