Abstract
In a voltage measuring apparatus for a plural battery according to the present invention, each of voltage detecting ICs (-) to (-) connects a switch SWto a reference voltage generatorand supplies a reference voltage Vf from the reference voltage generatorto an A/D converter. The A/D converterdigitizes the reference voltage Vf, which is transmitted to a main microcomputer. The main microcomputerfinds a theoretical value of the reference voltage according to an ambient temperature, compares the theoretical value with the measured value of the reference voltage Vf, and determines whether or not the voltage detecting accuracy of the first voltage detecting IC (-) is good.
