Problems solved by technology

In terms of storing data, a fixed storage space and allocation address are specified, and the storage space cannot be allocated reasonably, which often causes a certain amount of space waste
When obtaining data, it takes a lot of time to obtain all the data recorded by the system at one time, and the huge amount of data is not conducive to the later data analysis, which brings great difficulty to data analysis

Embodiment Construction

[0017] In order to facilitate those skilled in the art to understand the technical content of the present invention, the present invention will be further described in detail below in conjunction with the embodiments.

[0018] The battery management system of the present invention includes a main control unit and a slave control unit connected to the main control unit, and each slave control unit is provided with a storage circuit for collecting the data of each single battery in the corresponding battery pack. The parameter data is stored in pages in the storage circuit of the slave control unit. The main control unit is used to receive and store various extreme value information of each battery cell in each slave control unit, fault information during system operation, and event data such as charging, discharging, and faults. The slave control unit and the master control unit are connected to the host computer through the CAN bus to realize data communication.

Abstract

The invention relates to a data management method for a battery management system. The battery management system comprises a main control unit and auxiliary control units connected with the main control unit. The auxiliary control units are respectively provided with a storage circuit. The auxiliary units and the main control unit are respectively connected with an upper computer through a CAN bus to achieve data communication. When the battery management system runs, the auxiliary control units collect various parameter data of each single battery inside battery packs corresponding to the auxiliary control units respectively, and store the parameter data into the storage circuits of the auxiliary control units in a paging mode. The main control unit is controlled to only receive and store various extreme value messages of the single batteries inside the auxiliary control units and fault messages and event data in the system running process. According to the battery management system, data storage occupied space is reasonable, system freedom can be saved, and data are conveniently called and used.

Description

technical field [0001] The invention relates to the technical field of battery management systems, in particular to a data management method of the battery management system. Background technique [0002] At present, when the battery management system stores the historical data of the system, the master control unit completes the storage of all data, while the slave control unit does not store data. Since the main control unit not only undertakes data processing tasks, but also records all data, the load is relatively heavy, and usually in order to ensure that the data within a certain period of time can be recorded, the capacity requirements of the memory chip are relatively high. In terms of storing data, a fixed storage space and allocation address are specified, and the storage space cannot be allocated reasonably, which often causes a certain amount of space waste. When obtaining data, it takes a lot of time to obtain all the data recorded by the system at one time, ...
