Apparatus for measuring voltage
First Claim
1. An apparatus for measuring a voltage of a cell while scanning a group of cells in a cell stack in which a plurality of cells is electrically connected in series, the apparatus comprising:
- a first switching device which is connected in series with a signal line carrying a voltage of a cell;
a voltage detecting device for detecting the voltage of the cell, the voltage detecting device being electrically connected with signal lines which carry voltages of cells belonging to a group;
wherein when the first switching device is electrically connected with an interface between two successive groups of cells, the first switching device is shared by the two groups.

Abstract
An apparatus measures a voltage of a cell while scanning a group of cells in a cell stack, in which a plurality of cells is electrically connected in series. The apparatus has a first switching device and a voltage detecting device. The first switching device is connected in series with a signal line carrying a voltage of a cell. The voltage detecting device detects the voltage of the cell, which is electrically connected with signal lines carrying voltages of cells belonging to a group. When the first switching device is electrically connected with a connecting point between two successive groups of cells, the first switching device is shared by the two groups.
