<p>It is possible to constitute a battery module having a large number of charge/discharge cycles until the service life expires and requiring a short time for charging the battery module. The battery module (20) contains a rapid charge battery (23R) and a normal charge battery (23N). When the battery module (20) is placed on a charge table (10), the two batteries (23R, 23N) are both charged. A mobile device (30) contains a battery (33). When the mobile device (30) is placed on the battery module (20), the battery (33) inside the mobile device (30) is charged. When the battery of the mobile device (30) is charged by the battery module (20), the rapid charge battery (23R) is used with a higher priority and the normal charge battery (23N) is used after the rapid charge battery (23R) has become empty.</p> |
