Abstract
PURPOSE: To enable to prevent over-charge of battery, by forming the self-hold circuit including the relay contact when charge closes to full state and the temperature switch is restored.
CONSTITUTION: In rapid charging of the battery, the output of secondary side of the transformer 13 is rectified 14 to charge up the battery 20. In this case, when the temperature switch 15 is operated with the temperature rise of the heat dissipating units such as the transformer 13 and rectifier 14, the relay 12 is activated and the relay contacts 121 and 122 are selected to normally closed position for stationary charging. Further, when the battery 20 is charged close to full charge, the charging current remarkably decreases and the switch 15 is restored by temperature decrease at each part. But, since the contact 122 is in self-hold state, the battery 20 can be avoided from being overcharged without rapid charging.
