PURPOSE: A system and method for controlling heat transfer timing is provided to accurately control time transferring heat from a heat source to a plurality of batteries through a simple mechanism, and to transfer just enough heat to the batteries. CONSTITUTION: A system and method for controlling heat transfer timing controls a temperature of a battery by using a heat source(104), and comprises two temperature measurement devices(102,103), a heat calculation device, a power supply device, a temperature distribution judgment device, and a heat transfer timing control device(105). The temperature measurement devices measures temperatures at different positions in the battery. The heat calculation device calculates heat required to transfer to the battery. The power supply device supplies electricity corresponding with the heat to a heat source. The temperature distribution judgment device judges weather the inner temperature of the battery became uniform or not.
