A system for preheating batteries according to the present invention comprises: an opening signal receiving unit for receiving a door opening signal for opening doors of a vehicle; a temperature measuring unit for measuring the temperature of a battery pack connected to a starter in the vehicle; a control unit for outputting a forced discharge start signal by referencing information on the temperature measured by the temperature measuring unit, when the door opening signal is received by the opening signal receiving unit; and a forced discharge circuit unit for forcibly discharging a plurality of battery modules constituting the battery pack according to the forced discharge start signal. According to the present invention, low-temperature starting properties of the vehicle can be significantly improved by using heat self-generated from the batteries without significantly changing existing vehicle power supply systems, and efficient preheating is enabled without unnecessary consumption of the battery pack by allowing a vehicle user to determine the starting time of preheating.
