Claims

[Scope of utility model registration request]

A battery to be charged is charged with a constant current controlled charging current, and when the charging voltage of the battery reaches a peak voltage and then decreases by a predetermined amount from the peak voltage, the charging current is controlled by a charging voltage detection circuit. A charging device that completes charging of the battery by stopping or rapidly reducing output, comprising: a constant current circuit that controls the charging current at a constant current based on a voltage difference between a detection voltage of the charging current and a reference voltage; an initial current adjustment circuit that includes a capacitor that is charged at a predetermined time constant at the beginning of charging when the battery starts being supplied, and controls the reference voltage at the beginning of the charging start to gradually increase to a predetermined voltage by charging the capacitor; A charging device with.
