Battery control system and battery control method

摘要

When detecting a fault of a master control device, a slave control device refers to master-device-line information, and obtains line information to establish a connection with the other master control device. The slave control device transmits connection request information to the master control device extracted from the other master control devices. The other master control device determines whether or not it is connectable with the slave control device that has transmitted the connection request information, and transmits a determination result as connectability information. The slave control device switches a communication line to the other master control device when the received connectability information indicates the connectable status.

主权项

1. A battery control system comprising:
a plurality of slave control devices each controlling charging/discharging of a battery; and a plurality of master control device connected to each of the plurality of slave control devices via a first communication line and controlling the plurality of slave control devices connected to respective master control devices, the slave control device comprising:
a memory unit that stores master-device-line information containing line information to communicate with each of the plurality of master control devices;a fault monitoring unit that detects a fault of the master control device connected to the local slave control device;a master-device searching unit that searches the line information of an other master control device than the master control device connected to the local slave control device from the master-device-line information when the fault is detected;a connection-request-information generating unit which generates connection request information indicating a connection request with the other master control device and which transmits the generated connection request information to the other master control device;a connectability information obtaining unit that obtains, from the other master control device, connectability information indicating whether or not connection with the slave control device is possible; anda line switching unit that switches the first communication line from the master control device connected to the local slave control device to the other master control device when the connectability information indicates that a connection with the slave control device is possible, the master control device comprising:
a slave-device connection managing unit which receives the connection request information, determines whether or not a connection with the slave control device is possible, generates the connectability information indicating a determination result, and transmits the connectability information to the slave control device.
