Abstract
A battery pack heat exchanger, system, and method comprises a plurality of battery modules comprising a heat exchanger having an outer shell and a plurality of cylinders extending within the outer shell. A plurality of battery cells are positioned within the plurality of cylinders and a coolant is poured into the shell via a fill port. As a result, the coolant is able to absorb and dissipate localized heat produced by the battery cells throughout the heat exchanger. Therefore, if one battery cell undergoes a thermal run-away, the heat will be distributed throughout the shell volume thereby greatly reducing the likelihood that battery cells directly adjacent the run-away cell absorb the brunt of the heat and undergo thermal run-away themselves.
