Publication number: 20160233560Abstract: An object of the present invention is to provide a technology with which the time of stopping operations of storage battery groups in performing preventive maintenance and maintenance works of storage batteries in a power storage system can be reduced. In the power storage system of the present invention, a storage battery panel 3 transmits a first signal (F1) based on monitoring of states of storage battery packs 4 to a superordinate relay panel 2, and the relay panel 2 transmits a second signal (F2) based on the first signal to a superordinate power control device 1. A maintenance device 5 transmits, based on an operation of designating a storage battery panel 3 to be maintained by a maintenance person, a third signal (M) to the superordinate relay panel 2 of the storage battery panel 3 to be maintained, and the relay panel 2 masks and invalidates the first signal from the storage battery panel 3 to be maintained or the second signal based on the first signal in accordance with the third signal.Type: ApplicationFiled: September 17, 2014Publication date: August 11, 2016Applicant: Hitachi Chemical Company, Ltd.Inventors: Mitsuyoshi KANOH, Takashi HARA, Shoichi HIROTA, Akihiko EMORI

Patent number: 8581557Abstract: A direct-current power source apparatus in which a lithium-ion capacitor unit is used as an electric storage system and which can fully utilize the lithium-ion capacitor unit and maintain the supply of electricity to a load is provided. An electric storage system includes a lithium-ion capacitor unit and a lead-acid battery connected in parallel with a load, and a voltage detecting section that detects the voltage of the lithium-ion capacitor unit. When the voltage detecting section detects that the voltage of the lithium-ion capacitor unit has reached a unit lower-limit voltage, a control circuit outputs a conduction signal for causing a switching circuit to get into a conductive state. When the switching circuit gets into a conductive state, the secondary battery supplies an electric power to a motor. At this time, the secondary battery charges the lithium-ion capacitor unit.Type: GrantFiled: March 15, 2011Date of Patent: November 12, 2013Assignee: Shin-Kobe Electric Machinery Co., Ltd.Inventors: Mitsuyoshi Kanoh, Masahiko Amano, Yukio Iida, Yoshiki Hama, Keizo Yamada
