Abstract:
A highly reliable protection element for a storage battery is provided. A protection element includes a low melting point metal body and heater elements. The low melting point metal body is connected to a charger side line and a storage battery side line of a charge/discharge circuit. The heater element is connected to the storage battery side line and a switch, and the heater element is connected to the charger side line and a switch. When the switches are operated, a voltage that is not affected by a voltage drop of the low melting point metal body is applied to one of the heater elements, so that the low melting point metal body can be reliably fused.
