A vehicle battery cooling system includes a coolant pump configured to supply coolant fluid to multiple battery modules, multiple adjustable flow valves each configured to selectively control a rate of coolant fluid flowing to a corresponding one of the multiple battery modules, multiple temperature sensors each configured to measure a temperature of one of the multiple battery modules, and a battery thermal control module. The battery thermal control module is configured to obtain a temperature of each of the multiple battery modules, determine whether one or more of the multiple battery modules has a temperature above a specified overheating threshold value, and change a setting of one or more of the multiple adjustable flow valves to allow a greater flow of coolant fluid to the at least one battery module exceeding the specified overheating threshold value as compared to other ones of the multiple battery modules.
