BATTERY PACK WITH HEATER/VOLTAGE EQUALIZER AND METHOD FOR HIGH ALTITUDE LONG ENDURANCE AIRCRAFT

摘要

In at least one embodiment, a battery pack for a high altitude long endurance aircraft including a plurality of cells, a thin sheet heater between two of the plurality of cells, a balance circuit connected to the plurality of cells to the thin sheet heater, a battery monitor circuit connected to the balance circuit for balancing charging, and a thermal monitor circuit connected to the thin sheet heater. In at least one implementation, a method is provided for a battery pack for a high altitude long endurance aircraft, which includes determining whether a battery pack needs thermal adjustment, adjusting a temperature of the battery pack using a thin sheet heater interposed between two cells of the battery pack, and balancing charging to at least one battery cell using the thin sheet heater.
