STRING CONTROL UNIT AUTO-CONFIGURATION AND FAULT COMMUNICATION SYSTEMS AND METHODS

摘要

One embodiment of the present disclosure describes a battery control system including a first string control unit that controls operation of a first battery string and outputs a first serial communication signal, in which the first serial communication signal comprises a first frequency to indicate that the first string control unit is a master string control unit when a fault is not detected; and a second string control unit that controls operation of a second battery string; receives the first serial communication signal; determines that the second string control unit is a subordinate string control unit when the first serial communication signal comprises the first frequency; and outputs a second serial communication signal, in which the second serial communication signal comprises a second frequency to indicate that the second string control unit is the first subordinate string control unit when a fault is not detected.

主权项

1. A battery control system configured to control operation of a battery system, comprising:
a first string control unit communicatively coupled to a first serial bus, wherein the first string control unit is configured to:
control operation of a first battery string comprising a first one or more battery modules connected in series; andoutput a first serial communication signal to the first serial bus, wherein the first serial communication signal comprises a first frequency to indicate that the first string control unit is a master string control unit when a first fault is not detected in the first battery string; and a second string control unit communicatively coupled to the first serial bus and a second serial bus, wherein the second string control unit is configured to:
control operation of a second battery string comprising a second one or more battery modules connected in series, wherein the second battery string is coupled in series with the first battery string;receive the first serial communication signal from the first serial bus;determine that the second string control unit is a first subordinate string control unit when the first serial communication signal comprises the first frequency; andoutput a second serial communication signal to the second serial bus, wherein the second serial communication signal comprises a second frequency to indicate that the second string control unit is the first subordinate string control unit when a second fault is not detected in the second battery string.
