Voltage detecting device of assembled battery and assembled battery system comprising same

摘要

In the voltage detecting device according to the present invention, voltage detecting lines respectively extend from a plurality of voltage input terminals, a plurality of capacitative elements are respectively interposed on coupling lines each coupling two adjacent voltage detecting lines to each other, and the voltage detecting lines are connected to voltage detecting means. At least all the voltage detecting lines respectively disposed on the positive electrode side of the cells are each connected to ground via one or more disconnection detection resistors. The voltage detecting means detects a disconnection on a wire between each of a plurality of voltage detecting points of the assembled battery and a plurality of voltage input terminals based on voltage inputted from each voltage detecting line.
