Claim 5:
6. The method of claim 1, wherein directing the air flow comprises:
opening a first valve that controls the air flow from the hot gas outlet of the non-metal-air battery pack, wherein opening the first valve is performed in response to a non-metal-air battery pack pressure within the non-metal-air battery pack exceeding a first preset pressure, wherein the first preset pressure corresponds to a pressure at which at least one of a plurality of non-metal-air cells within the non-metal-air battery pack enters into thermal runaway;
closing a second valve that controls air flow from a primary air source through the air inlet of the metal-air battery pack and through the plurality of metal-air cells within the metal-air battery pack, wherein the primary air source is different from the hot gas outlet, and wherein closing the second valve is performed in response to the non-metal-air battery pack pressure exceeding the first preset pressure;
closing a third valve that controls air flow out of the metal-air battery pack and to an ambient environment, wherein closing the third valve is performed in response to the non-metal-air battery pack pressure exceeding the first preset pressure; and
opening the third valve that controls air flow out of the metal-air battery pack and to the ambient environment, wherein opening the third valve is performed in response to a metal-air battery pack pressure within the metal-air battery pack exceeding a second preset pressure or in response to a metal-air battery pack temperature within the metal-air battery pack exceeding a preset temperature, and wherein opening the third valve occurs after closing the third valve.
