Abstract

PURPOSE:To supply the power required for the function and operation, to the car- mounted radio device, even if the voltage of the battery for power is less than the specified voltage by the lamps forgotten to distinguish. CONSTITUTION:When the generator 1 is operative, direct electric charging is made to the main battery 2. But, since the slave battery 3 is charged through the reverse- current blocking diode 9, if the voltage of the main battery 2 is low due to any cause, no voltage of the slave battery 3 is lowered. The voltage comparator 4 compares the voltage of the batteries 2, 3, and when the voltage difference of the batteries 2, 3 is a given voltage or more, the switching signal is fed to the controller 5, where the switch 6 is operated by, the signal from the voltage comparator 4, allowing to instantly connect the power supply terminal of the car mounted radio device 7 to the battery having higher voltage among the batteries 2, 3. The electric circuit for car 8 is always connected to the main battery 2 irrespective of the result of the voltage comparator 4.
