<p>The present invention relates to a temperature balancing control system for vehicle battery modules. The system individually controls the temperature of the battery modules to actively reduce the temperature difference between the battery modules. The present invention connects high-voltage cables having individual control relay units on both ends of heating wires in the respective battery modules while the heating wires of the respective battery modules are connected in series through positive and negative cables and turns the individual control relay units on and off according to the BMS control operation. Accordingly, the present invention can elevate the temperature of a selected battery module to match the temperature level of other battery modules, thereby actively reducing the temperature difference between all of the battery modules.</p> |
