Abstract
A controllerfor estimating a maximum internal temperature of a battery packprocesses battery pack input/output limitations. The controllerestimates: a difference between a surface temperature and an internal temperature of the battery pack; a temperature difference that is dependent on different internal resistances of unit cellsa temperature difference that is dependent on contact states of a plurality of temperature sensorswith the battery pack; and a temperature difference that is dependent on different detection characteristics between the temperature sensors. The controllerfurther limits the input/output electric power of the battery packbased on the estimated maximum internal temperature.
