Abstract
Provided is a battery module including a battery part including one battery cell or a plurality of battery cells connected in series, first and second leads respectively led out from a positive electrode and a negative electrode of the battery part, a first FET in which the first FET is an N-channel type and a drain of the first FET is connected to the first lead and a source of the first FET is connected to a positive output terminal, a negative output terminal connected to the second lead, a pre-discharge circuit provided in parallel with a drain-source path of the first FET and is configured to raise a potential of the positive output terminal prior to an ON state of the first FET at discharging, and a forced OFF circuit configured to turn off the first FET by short-circuiting between a gate and the source of the first FET.
