Abstract
A current leakage detection circuit that detects current leakage from a battery having a first electrode and a second electrode, which is either the positive electrode or the negative electrode opposite to the first electrode, to a chassis includes: a detection circuit including a reference voltage source terminal, a first detection terminal, and a ground terminal connected to the first electrode; a first resistor connected between the second electrode and the chassis; a second resistor connected between the chassis and the first detection terminal; and a third resistor connected between the first detection terminal and a predetermined terminal. When the first electrode is the positive electrode, the predetermined terminal is the reference voltage source terminal. When the first electrode is the negative electrode, the predetermined terminal is the first electrode. The detection circuit detects an occurrence of current leakage based on a voltage of the first detection terminal.
