<p>The present invention relates to techniques for charging a battery at high speed, more particularly to techniques for shortening the charging duration by utilizing a plurality of small-capacity battery packs to increase the battery capacity and by supplying power and charging each of the plurality of low-capacity battery packs. According to the present invention, as a large-capacity battery is configured by combining a plurality of small-capacity battery packs, the overall battery capacity is increased yet the duration of battery charging is shortened, so as to advance improving portability of a portable information appliance. In addition, since a large-capacity battery can be divided into a plurality of small-capacity battery packs of a certain capacity and shape that are scattered in different locations inside a device, it is possible to allow greater design freedom for products. Further, the large-capacity battery which is configured with plural battery packs in a switching structure can be controlled as a single large-capacity battery.</p> |
