Claims20
A first device, comprising:
- at least one processor;
- a battery that powers the at least one processor;
- storage accessible to the at least one processor;
- and
- circuitry to, responsive to a user command to decommission the battery, discharge the battery to render the battery inoperable.
2 more elements
A method, comprising:
- receiving, at a device comprising a battery, a user command to decommission the battery;
- and
- responsive to receiving the user command, decommissioning the battery via battery self-discharge, decommissioning the battery comprising rendering the battery permanently inoperable.
A battery pack, comprising:
- one or more battery cells;
- a processor;
- and
- firmware that, under control of the processor and responsive to receipt of a user command to decommission the battery pack, uses a circuit within the battery pack to concurrently discharge each of the one or more battery cells.
