Abstract
An example embodiment includes a battery having a plurality of battery modules, each battery module comprising a plurality of battery cells; a pressure control system configured to provide fluid having a target fluid pressure that achieves a target pressure to be applied to respective battery cells of a battery module; and a thermal control system configured to supply coolant to the battery module to achieve a target temperature.
Claims20
A thermal control system for a battery having a plurality of battery modules, the thermal control system comprising:
- a coolant supply system configured to supply hot coolant and cold coolant;
- a thermal management control module configured to set a target temperature for each battery module of the battery;
- and
- a plurality of temperature control units, each temperature control unit configured to control a temperature of a respective battery module independently from other battery modules of the battery, wherein a temperature control unit of the plurality of temperature control units comprises (i) one or more valves, and (ii) a valve control unit configured to control actuation of the one or more valves based on an actual temperature and the target temperature of the respective battery module,
- wherein the one or more valves are configured to control flow of the hot coolant and the cold coolant received from the coolant supply system, and wherein the temperature control unit is configured to supply a mixture of the hot coolant and the cold coolant to the respective battery module to achieve the target temperature.
