とを特徴とする充電器。Above is a switching element that is attached to the rectifier of the power supply that supplies the storage battery and short-circuits the resistor when the temperature rises to increase the charging current! A thermistor that detects the temperature rise of the battery and converts it into a voltage, an analog value memory that stores the above signal, a clock generator that performs sampling operation of this analog value memory at regular intervals, and a difference between the stored voltage and the end-of-charge voltage. At the start of charging, the voltage of the thermistor installed near the storage battery is stored in an analog value memory, and as charging progresses, the temperature of the rectifier increases and the resistor is short-circuited with a metal wire. and increases the charging current, and compares and detects the thermistor voltage, which decreases due to a rapid temperature rise at the end of charging as the storage battery voltage rises, and the memorized voltage, and when a predetermined voltage difference is reached, A charger characterized by stopping charging.
