る。However, in non-contact rechargeable electric toothbrushes, the types of main bodies having different power storage elements are increasing due to diversification of brushing operation and the like. This is because current consumption changes due to different brushing operations and the like, and it is necessary to use power storage elements having different capacities to keep the brushing time constant.

いう問題があった。[0004] If the charging current is too large, the service life of the power storage element may be affected. If the charging current is too small, the charging time is prolonged. Therefore, the charging current must be changed depending on the power storage element. For this reason, it is necessary to use different chargers for the main units using different power storage elements, and there is a problem that the types of chargers increase.
In addition, there is a problem in that the number of types of chargers is increased, so that the battery pack is easily erroneously inserted into another charger. In addition, since the charger cannot be used in common, there is also a problem that a different charger must be obtained in order to use a different main body. Japanese Unexamined Patent Application Publication No. 8-1987 corresponds to this, but in this conventional example, a complicated method using a CPU or the like that obtains information on a battery serving as a power storage element and controls a charging current is used. There is a problem that a circuit is required and the cost is high.
