Patent number: 10442374Abstract: 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.Type: GrantFiled: December 9, 2014Date of Patent: October 15, 2019Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Atsumi Kondo, Kazuto Kuroda, Tatsuya Arai, Masaki Sato, Akinobu Nishikawa, Shinichiro Kosugi, Masahiro Sekino, Hideaki Yasui, Mai Honda, Masahiro Kurosu, Kotaro Ogawa, Tomonao Takamatsu, Mitsunobu Yoshida, Takafumi Nakahama, Akihiko Ujiie

Patent number: 10340564Abstract: 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.Type: GrantFiled: January 6, 2015Date of Patent: July 2, 2019Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Akinobu Nishikawa, Shigeki Kono, Masaki Sato, Tatsuya Arai, Kotaro Ogawa, Shinichiro Kosugi, Masahiro Sekino, Kazuto Kuroda, Hideaki Yasui, Mai Honda, Tomonao Takamatsu, Mitsunobu Yoshida, Takafumi Nakahama, Akihiko Ujiie, Atsumi Kondo, Masahiro Kurosu
