Abstract
A battery pack composed of an array of secondary cells includes first and second electrodes for charging and discharging the battery pack. The battery pack has a temperature detecting element disposed below the first and second electrodes. The temperature detecting element is electrically connected through a lead to a third electrode in the form of a thin sheet disposed between the side of one of the cells and a lower casing member of a battery pack casing. The first and second electrodes remains in the same position as those of conventional battery packs. The battery pack can be charged by a battery charger which has a third terminal for receiving a temperature signal supplied from the temperature detecting element through the third electrode. The charging process for charging the battery pack is controlled based on the temperature of the cells as detected by the temperature detecting element. The battery charger is compatible for use with different types of battery packs such as battery packs of nickel-cadmium and nickel-hydrogen cells.
