Claims

[Scope of utility model registration request]

An electrical system overload system for a vehicle that has a load that is not directly related to the running of the vehicle and a breaker that cuts off the load from the alternator and battery when an overload in the vehicle electrical system is detected depending on the battery condition. In the load protection device, at least the voltage across the battery has decreased to a first detected value at which the load cannot be driven;
a voltage detection section that detects that the detected value has increased to a second detected value that can drive the load; a counter that starts counting for a certain period of time when the voltage detection section detects the second detected value; and a voltage detection section. a cutoff controller that controls a cutoff controller to cut off the load from the alternator and the battery when a first detection value is detected, and to make the load conductive to the alternator and the battery in response to a count end signal from a counter; A vehicle electrical system overload prevention device consisting of an indicator that lights up when the alternator and battery are disconnected.
