<p><P>PROBLEM TO BE SOLVED: To provide a cooling system which saves on power consumption when a battery is charged by an external power supply. <P>SOLUTION: In the present embodiment of the invention, a cooling system 1 subtracts, from the battery usage upper-limit temperature, an increased portion of the battery temperature when the remaining capacity of the battery has all been used up in any predictable running state, to calculate a target temperature in the present embodiment. As a result, the target temperature in the present embodiment decreases proportionately as the SOC (state of charge) increases. Conversely, a target temperature in the conventional technology was set at a constant level relative to the SOC. Therefore, a difference between the target temperature in the present embodiment and a target temperature in the conventional technology is a reducible amount of power consumption. Accordingly, the cooling system 1 in the present embodiment can save on power consumption when the battery is charged by an external power supply. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
