Abstract
In a voltage detection apparatus for detecting voltage of battery modules, it is possible to detect that a shut-off element performed operation in a certain one of a plurality of battery modules connected in parallel. The voltage detection apparatus detects voltage of the plurality of battery modules each including a shut-off element and connected in parallel with respect to a load, and decides whether the shut-off elements are operating based on the cell voltage in a state that the plurality of battery modules are disconnected from a power supply line by switching wares.
