ABSTRACT:
A safety device is wired in series with selected accessories in a wiring circuit for a vehicle. The safety device of the present invention determines the state of charge of the battery as a function of the rate of discharge of the battery. When the state of charge falls below preset values, the device activates a switch which disconnects the battery from the vehicle wiring circuit in order to save sufficient energy for engine ignition. In another embodiment, a programmed microprocessor activates electronic switches to sequentially disconnect banks of accessories from the battery.
