A battery system in which delay in communication and processing is restrained even if the battery system is constructed with plural hierarchical structures is provided. The battery system includes: a battery module 30 having plural battery cells 20 and a battery module control unit 31 which collects battery information of the plural battery cells 20; a battery pack 40 having plural battery modules 30 and a battery pack control unit 230 which collects information of the plural battery modules 30; and a battery block 50 having plural battery packs 40 and a battery block control unit 240 which collects information of the plural battery packs 40. The battery module control unit 31 and the battery pack control unit 230 communicate with each other via a first communication line. The battery pack control unit 230 and the battery block control unit 240 communication with each other via a second communication line. The battery module control unit 31 and the battery block control unit 240 have a communication line in which direction communication is carried out without having a relay of the battery pack control unit 230. |
