Patent number: 10144305Abstract: According to some embodiments, a battery control device has a current detector, a storage, and a state determiner. The current detector detects a current value of a current which flows into a second battery which is connected in parallel to a first battery. The first battery and the second battery are charged with a fixed current. The storage stores an initial value of the current which flows into the second battery if the second battery is charged with the fixed current in an initial use stage of the second battery. The state determiner determines a state of the first battery based on the current value detected by the current detector and the initial value stored in the storage.Type: GrantFiled: June 28, 2016Date of Patent: December 4, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Kaoru Koiwa, Hitoshi Nirasawa, Hideo Yamasaki, Takeshi Yasuda, Hiroki Matsushita, Tomomi Kageyama

Patent number: 10109841Abstract: According to one embodiment, in a storage cell system, cell lines each formed by connecting a prescribed number of storage cells in series are connected in parallel to form a storage cell module. Each unit is formed by connecting a prescribed number of storage cell modules in parallel. Outputs of a number of units corresponding to load capacity are linked in parallel and supplied to a load. At this time, current is limited to an extent that the storage cells are not damaged by interposing a current-limiting resistor in an output line of the storage cell module.Type: GrantFiled: December 12, 2017Date of Patent: October 23, 2018Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Hiroyuki Kobayashi, Fujio Nomura, Kaoru Koiwa, Takeshi Yasuda, Tomomi Kageyama

Patent number: 9539963Abstract: In a battery system for use in a vehicle as power supply, a plurality of battery groups, each configured to output a rated voltage while being charged, in parallel to an input/output system line by a system connection device, BMU devices monitor the battery groups, respectively, determining whether the battery groups enter an abnormal state, and any battery group entering the abnormal state is designated and disconnected from the input/output system line. If a predetermined of battery groups are found to enter an abnormal state, as determined by the BMU devices, a system controller generates an alarm, informing the user that the battery system may not provide power in the required amount.Type: GrantFiled: January 17, 2013Date of Patent: January 10, 2017Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Tomomi Kageyama, Hiroyuki Kobayashi, Fujio Nomura

Patent number: 8954095Abstract: According to one embodiment, a measurement system includes a wireless relay device, a moving-object-mounted terminal and a data processor. The wireless relay device forms a wireless area for performing wireless communication. The moving-object-mounted terminal is mounted to a moving object within the wireless area. The moving-object-mounted terminal includes a Global Positioning System (GPS) unit and a wireless unit. The GPS unit acquires positional data of the moving object and time data indicating the time when the positional data has been acquired by GPS. The wireless unit converts the positional data and the time data into a wireless signal, and transmits the wireless signal to the wireless relay device. The data processor receives the wireless signal from the moving-object-mounted terminal via the wireless relay device, and calculates time required for the moving object to move a predetermined distance within the wireless area based on the positional data and the time data.Type: GrantFiled: December 6, 2011Date of Patent: February 10, 2015Assignee: Kabushiki Kaisha ToshibaInventors: Tsutomu Watanabe, Tomomi Kageyama
