Battery voltage measurement device
First Claim
1. A battery voltage measurement device comprising:
- a plurality of first switching sections, wherein each pair of adjacent first switching sections sequentially selects two output terminals of each of a plurality of battery blocks included in a battery pack so that each of the selected output terminals are connected to one of a pair of conductor wires;
a voltage detection section for detecting a battery voltage of each of the plurality of battery blocks via the pair of conductor wires; and
second switch sections each being provided on a respective one of the pair of conductor lines and being serially connected to each group of the plurality of first switch sections connected in parallel to one of the pair of conductor lines.
