A storage battery device including a housing, battery packs, and a heat detection member having a linear structure. The battery packs are accommodated in the housing. The battery packs are electrically connectable to each other. The heat detection member has a heat detection function and continuously extends while making thermal contact with a member located near bottom surfaces of the battery packs.

Storage battery device

According to one embodiment, a vehicle-use storage battery system includes a storage battery, a main circuit, a circuit breaker, a storage battery management unit, a first determiner, and a second determiner. The main circuit is electrically connected to the storage battery. The circuit breaker is disposed between the storage battery and the main circuit to make or break the electrical connection therebetween. The storage battery management unit manages an operating state of the storage battery. The first determiner determines whether to break the electrical connection between the storage battery and the main circuit by means of the circuit breaker. The second determiner determines, on the basis of at least one of operating states of the storage battery management unit, the first determiner, and the circuit breaker, whether to break the electrical connection between the storage battery and the main circuit by means of the circuit breaker.

Vehicle-use storage battery system

According to one embodiment, a vehicular storage battery device includes a housing, battery boxes, and a common cooling passage. The battery boxes are disposed in the housing. Each of the battery boxes houses an electric cell as a vehicle power source and includes a heat transporting part transporting heat generated in the battery box to outside of the battery box. The common cooling passage is disposed in the housing. The common cooling passage is provided with an inlet for taking in a fluid and an outlet for discharging the fluid having passed through the passage. The inlet and the outlet are open in a direction different from a traveling direction of the vehicle. The heat transporting part of each of the battery boxes is exposed to inside of the passage.
