Abstract

PURPOSE:To realize a battery device with the sensor function which can be used in common regardless of stored batteries by providing heat transfer systems for detecting the surface temperature of a battery on a case storing the batteries. CONSTITUTION:The surface temperature of a cylindrical battery 12 in a battery pack is transferred to a temperature sensor 19 converting the temperature into an electrical signal such as a thermistor via heat transfer tools 15, 17 and detected. Cylindrical batteries 11-13 with the same characteristic are used for the battery pack, when the surface temperature of the battery 12 is detected, the surface temperature of the batteries 11, 13 is nearly the same. The temperature sensor 19 is not required to be put in the battery pack, only one temperature sensor 19 provided on the charging device side is sufficient, and the error of the temperature sensor 19 can easily be adjusted.
