Claims (1)

[Scope of utility model registration request] at least two push-button switches; a voltage determining means for determining whether or not a battery charging voltage has reached the voltage value; a predetermined voltage value is set as a reference voltage corresponding to each of the switches; Predetermined time data is set corresponding to each of the switches, and after the voltage determining means determines that the voltage of the battery has reached the voltage value, time is measured based on the time data. and a charger control device that terminates charging after a predetermined time has been measured by the timer, and the charger control device determines whether two or more of the switches are pressed at the same time. switch determining means; and test voltage setting means for setting the reference voltage of the voltage determining means to a test voltage lower than a predetermined voltage value when the switch determining means determines that the switches are pressed simultaneously. and test time setting means for setting test time data of a value smaller than the predetermined time data in the time measurement means when the switch determination means determines that the switches are pressed simultaneously. charger control device.
