Automatic Active Locking Battery

Apparatus and associated methods relate to a battery housing configured to selectively lock a battery to the housing when the battery is operated into electrical communication with the housing. In an illustrative example, the housing may have a first indexing member configured to slidingly engage a second indexing member of the battery such that a power terminal of the housing is brought into register with a power terminal of the battery. The housing may, for example, have a control module operably coupled to the housing power terminal and configured to operate the (mechanical) locking module between a lock mode and an unlock mode. The control module may, for example, be configured to operate the locking module into the lock mode when the power terminals are operated into electrical connection with each other. Various embodiments may advantageously automatically lock and/or unlock a battery module in response to predetermined operations.
