A controller 50 for estimating a maximum internal temperature of a battery pack 14 processes battery pack input/output limitations. The controller 50 estimates: a difference between a surface temperature and an internal temperature of the battery pack 14; a temperature difference that is dependent on different internal resistances of unit cells 12; a temperature difference that is dependent on contact states of a plurality of temperature sensors 32 with the battery pack 14; and a temperature difference that is dependent on different detection characteristics between the temperature sensors 32. The controller 50 further limits the input/output electric power of the battery pack 14 based on the estimated maximum internal temperature. |
