ABSTRACT:
A mobile radio equipment has a built-in storage battery that permits radio equipment to be used outside of the vehicle, but the vehicle's battery and charger are needed to charge up or maintain the charge of the internal storage battery of the radio equipment most of the time. A d.c. voltage converter is used when the radio equipment is in the vehicle to provide at least one voltage which the internal storage battery provides to the radio equipment and that voltage of the internal battery is connected, when the radio equipment is in the vehicle, to the radio equipment through a control switch which is closed only when the output of the voltage converter is less than the voltage of the internal storage battery of the radio equipment. In the power supply located in the vehicle the output of the voltage converter also needs a regulator to supply a regulated voltage to the radio equipment, in addition to the prior unregulated voltage.
