BATTERY THERMAL MANAGEMENT SYSTEM WITH PASSIVE BATTERY PACK COOLING

摘要

According to one embodiment, a battery module includes an output connector, several battery cells that are coupled to the output connector and are at least partially submerged within a liquid coolant. The battery cells are configured to provide battery energy to a load via the output connector and are configured to draw power from an external power supply to charge the battery cells via the output connector. While the battery cells provide the battery energy or draw power, the battery cells generate heat that is transferred into the liquid coolant, thereby causing at least some of the liquid coolant to turn into vapor extracting the heat. The battery module also includes a condenser that is positioned above the battery cells and is configured to condense the vapor back into liquid coolant.
