Abstract: The present invention reduces the effort involved in an operation for cancelling a current cutoff device while inhibiting a capacity decline during parking. Provided is a battery device 20 that is to be mounted on a vehicle, and that is provided with: an assembled battery 30 that supplies electric power to loads 10 including an engine starting device 10A; a current cutoff device 45 that cuts off an electric current to the loads 10 from the assembled battery 30; and a control unit 70, wherein upon detecting a parked state of the vehicle, the control unit 70 operates the current breaker device 45 so as to execute a current cutoff process for cutting off the current flowing from the assembled battery 30 to the loads 10, and following the execution of the current cutoff process, if a prior action to be performed on the vehicle by a user before starting driving is detected, the control unit 70 cancels the cutoff of current by cancelling the operation of the current breaker device 45.

Abstract: The present invention addresses the problem of diagnosing a failure of a discharge resistor, while suppressing deterioration of discharge capacity. Disclosed is a failure diagnostic device for a discharge circuit 60 for discharging electricity from an electricity storage element 31. The discharge circuit 60 includes a resistance circuit 61 comprising a plurality of resistor blocks B connected in parallel, and each of the resistor blocks B comprises a plurality of discharge resistors Ra, Rb connected in series. During the time when electricity is being discharged from the electricity storage element 31, the failure diagnostic device diagnosis a failure of the resistance circuit 61 on the basis of a voltage or a current at a connection point P between the discharge resistors Ra, Rb.

Abstract: An energy storage apparatus includes an outer case, and an energy storage device housed in an inside of the outer case. The outer case includes a ventilation chamber which makes the inside and an outside of the outer case communicate with each other. The ventilation chamber includes a front wall in which a through hole communicating with the outside is formed, a back wall disposed at a position where the back wall opposedly faces the front wall, a first wall disposed between the through hole and the back wall, and a first side wall disposed in an extending manner along a first direction which intersects with the front wall with a gap formed between the first side wall and the first wall. The gap is formed over a distance from the front wall to the back wall along the first direction.
