Abstract
A battery system for an automotive vehicle includes a battery case having a number of battery cells housed within the case. Coolant passages extend about the battery cells, and a coolant pump or driver circulates coolant from the coolant supply through the passages so as to transfer heat from the battery cells to the coolant. A controller periodically reverses the direction of flow through the coolant passages so as to minimize the differential temperature arising between various cells of the battery stack.
