PROBLEM TO BE SOLVED: To provide a battery voltage detector easy to handle and capable of frequently performing an output error compensating operation. SOLUTION: This device comprises a reference voltage generation part 4 having a mutually serially connected reference voltage generation switch SW0 and Zener diode ZD, which is interposed between a block selection part 3 for selecting a prescribed cell block of a set battery 1 and a voltage detection part for detecting the output voltage of the block selection part 3. Accordingly, a battery voltage detector capable of performing the error correction of the voltage detection part 2 at any time can be realized with a simple circuit structure. |
