電装置。[Claims for Utility Model Registration] (1) A charging device that has a charging circuit that performs joggle charging control that supplies charging current until the battery voltage reaches a predetermined voltage and then supplies charging current again when the battery voltage drops to a predetermined value. The device includes a detection means for detecting the ON-OFF repetition period of the charging current, and based on the detection signal of this detection means, if there is no repetition, it is determined that the battery connection is not normal, and when the repetition period is equal to or higher than a predetermined value. and determining means for determining that the battery is over-discharged. (2) At least one electrode of the battery receiving part is divided into a plurality of parts, and when a battery is attached to the receiving part, the electrodes of the battery are configured to short-circuit between the electrodes and close the charging circuit. A charging device characterized by:
