Original Abstract Submitted

A battery string is configured such that a plurality of battery circuit modules can be connected in series. A middle point between a first capacitor and a second capacitor provided on a detection line connecting a positive electrode output line and a negative electrode output line of the battery string to each other is grounded by a ground line through a limiting resistor. During operation of the battery string, an electric leakage detection unit sets a battery circuit module in a pass-through state, and detects electric leakage in the battery string based on a differential voltage that is a difference between a first voltage being the voltage of the first capacitor and a second voltage being the voltage of the second capacitor.
