Claims

[Scope of Claim for Utility Model Registration] A protection circuit for a battery circuit that has a battery relay that opens and closes in accordance with the switching position of a starter switch, and that is opened and closed by the opening and closing of the battery relay, which is interposed in the battery circuit. A current limiting circuit that connects a shunt, a protective relay having a relay contact connected in series to a relay coil constituting a battery relay, and a relay coil that opens and closes the relay contact, and an input/output terminal of the shunt. A protection circuit for a battery circuit, comprising: a shunt circuit in which a resistor and the protective relay coil are connected in series.
