Abstract
A semiconductor device including: lines connected to lines between respective neighboring battery cells of plural battery cells connected in series; at each of the battery cells, a voltage detection portion that detects a battery voltage value of the battery cell based on a voltage provided by the lines connected to the high potential side of the battery cell and to the low potential side of the battery cell; and at each of the lines, a regulation portion that regulates current to make a first current and a second current cancel out, the first current being caused to flow in a first direction in the resistor element by the battery cell at the high potential side of the line, and the second current being caused to flow in a second direction in the resistor element by the battery cell at the low potential side of the line.
