Abstract:

A zinc-air charger having a case defining a plurality of pass core vents, and an internal case cavity; a plurality of zinc-air cells that are electrically coupled and disposed within the internal case cavity; a coupling plug configured to couple with and provide electrical power generated by the plurality of zinc-air cells to a device that is separate from the zinc-air charger; and a system configured to: output electrical power generated by the plurality of zinc-air cells to the device; identify a state of the plurality of zinc-air cells, determine, based at least in part on the identified state of the plurality of zinc-air cells, that one or more of the plurality of zinc-air cells are air-starved, and in response to determining that the one or more of the plurality of zinc-air cells are air-starved, generate a power cut-off for a period of time that ceases electrical power output to the device.
