However, due to maintenance or replacement, the battery modules in the battery pack will change, and the battery status information of the corresponding battery modules will also change, such as SOC (state of charge), SOH (state of health), etc. will change
Since the battery management system cannot identify whether the battery module has been replaced, nor can it know the initial battery performance status of the new battery module, therefore, the subsequent estimated performance status of the entire power battery may be inaccurate

The invention proposes a power battery management system, a control method and a vehicle. The system comprises a master control plate and a plurality of slave control plates, wherein the plurality of slave control plates are arranged in a plurality of battery modules in one-to-one correspondence; when the management system is energized, the plurality of slave control plates are used for respectively reporting stored information of the battery modules to the master control plate, and the battery module information comprises identification information and battery module state information; and the master control plate is used for verifying the battery module information sent from the plurality of slave control plates, and the battery module information sent from the battery module is stored and updated when the received identification information is judged not to be consistent with the identification information stored in the master control plate. By the power battery management system, whether the battery modules are replaced or not can be simply and conveniently detected, moreover, the performance state of a power battery can be accurately estimated in real time no matter whether the battery module is replaced, and an estimation result is objective and reliable.
Description
technical field [0001] The invention relates to the technical field of battery performance monitoring, in particular to a power battery management system, a control method and a vehicle. Background technique [0002] The power battery system of an electric vehicle includes a power battery composed of multiple battery modules, and each battery module includes multiple single cells. The battery management system estimates the performance status of the entire power battery by monitoring each battery module. Such as SOC (state of charge), SOH (state of health) and so on. However, due to maintenance or replacement, the battery modules in the battery pack will change, and the battery status information of the corresponding battery modules will also change, such as SOC (state of charge), SOH (state of health), etc. will change. Since the battery management system cannot identify whether the battery module has been replaced, nor can it know the initial battery performance state of ...
