Abstract
An assembled battery system is disclosed that includes a plurality of serially-connected battery cells; voltage detecting lines connectable at one ends to electrodes of the battery cells of the assembled battery; electric resistors serially-connected at one ends to the other ends of the voltage detecting lines; capacitors connected to the other ends of the electric resistors, each of the capacitors being configured to electrically interconnect one of the voltage detecting lines and the other voltage detecting line; voltage measuring circuits connected respectively to each of the voltage detecting lines; electrically openable short-circuiting switches arranged between the capacitors and the voltage measuring circuits and parallel-connected to the capacitors; and a monitoring circuit that detects a difference between a first measurement result and a second measurement result with respect to each of the short-circuiting switches and a failure of the voltage detecting lines, the short-circuiting switches or the voltage measuring circuits.
