Abstract

A battery component and a battery system are disclosed in this invention. Necessary information is obtained without connecting a signal line between an electronic device and a charging device, so that it becomes possible to provide a highly value-added function without deteriorating convenience and portability of the charging device and the electronic device.

Description

technical field [0001] The present invention relates to battery packs and battery systems using such battery packs. Background technique [0002] The inventors of the present application have previously proposed a charger capable of indicating the possible driving time of an electronic device using the battery to be charged and its current charging capacity when charging a battery pack, such as Figure 1-4 shown. [0003] This charger will be described below. exist figure 1 In, reference numeral 1 denotes a charger packaged in an electronic device having a built-in video camera, such as a video tape recorder (hereinafter referred to as a camcorder) or the like. In addition, refer to figure 1 , reference numeral 2 denotes an AC adapter 2 connected to a commercially available power source to supply the power to the camcorder and charger 1 . [0004] The charger 1 includes a charging circuit 3, a calculation processing microcomputer 5 and a display 6, and the charging cir...
