Abstract
Unnecessary consumption of power of an auxiliary primary battery 2, and other problems have been inherent in a conventional battery system. Such problems have occurred because of frequent switching from a main battery to the auxiliary primary battery 2 when power is supplied from the main battery loaded on a vehicle to emergency call devices 6 and 7. According to the present invention, a novel battery switching device is disclosed, capable of executing automatic switching at a voltage for making operable the emergency radio signal generation circuit 6 of an emergency call device, and executing switching based on the starting signal of a manual switch 17 or an air bag at a higher voltage.
