Abstract:
1. A semiconductor circuit comprising: a plurality of battery voltage signal lines, each signal line connected to both ends of each of a plurality of batteries that are connected in series; a first connection portion, provided at each battery voltage signal line, that connects the battery voltage signal line with a first signal line; a second connection portion, provided at each battery voltage signal line, that connects the battery voltage signal line with a second signal line; a first voltage supply section, provided at each battery voltage signal line, that supplies the battery voltage signal line with a voltage higher than a voltage at a high potential side of the battery to whose low potential side the battery voltage signal line is connected; a second voltage supply section, provided at each battery voltage signal line, that supplies the battery voltage signal line with a voltage lower than a voltage at the low potential side of the battery to whose high potential side the battery voltage signal line is connected; and a comparison section that compares a voltage of the first signal line with a voltage of the second signal line, and that outputs a comparison result.
