Data acquisition method, device, system and equipment and storage medium

Abstract

The invention discloses a data acquisition method, device, system and equipment and a storage medium. The method comprises the steps that a controller sends a driving instruction to N communication chips; wherein the types of the N communication chips are different, N is greater than or equal to 2, and N is an integer; each communication chip sends a confirmation signal to an acquisition board group based on the driving instruction; wherein the acquisition board group comprises a plurality of acquisition boards; each acquisition board is provided with a plurality of analog front-end chips; if the communication chip receives a reply signal sent by the acquisition board group, determining the communication chip as a target communication chip; and the target communication chip establishes connection with the plurality of analog front-end chips of each acquisition board to form a plurality of data transmission channels, and acquires the state data of the battery cell based on the plurality of data transmission channels. According to the technical scheme, the problem that the mainboard needs to be replaced due to the fact that the types of the communication chips of the mainboard are not matched is solved.

Description

technical field [0001] The invention belongs to the technical field of battery packs, and in particular relates to a data acquisition method, device, system, equipment and storage medium. Background technique [0002] At present, due to the different parameter configurations of Battery Management System (BMS) produced by different manufacturers, the same type of communication chip and Analog Front End (AFE) must be matched during use, and then it can work normally. The status data of the battery pack is collected, that is, the BMS produced by different manufacturers cannot be used in common. [0003] However, in practical applications, different users may choose different types of acquisition boards according to their own needs, corresponding to different types of AFEs. In order to match the communication chip and AFE, the BMU needs to be replaced, and the replacement of the motherboard is for users. , which is time-consuming, labor-intensive and costly.

AI Technical Summary

Problems solved by technology

[0002] At present, due to the different parameter configurations of the battery management system (Battery Management System, BMS) produced by different manufacturers, the same type of communication chip must be matched with the analog front end chip (Analog Front End, AFE) during use, and then it can work normally. Collect the status data of the battery pack, that is, BMS produced by different manufacturers cannot be used universally

[0003] However, in practical applications, different users may choose different types of acquisition boards according to their own needs, corresponding to different types of AFEs. In order to realize the matching between the communication chip and AFEs, it is necessary to replace the BMU. , time-consuming, laborious and costly

[0004] In addition, for BMS manufacturers, the configured motherboards will have fixed parameter configurations for the communication chips, and different motherboards will produce different communication chip models, with huge data, complicated management, and high development costs.
