Intelligent battery pairing repair method and system

Abstract

The invention provides an intelligent battery pairing repair method, comprising steps of connecting a human-machine interaction system with an old battery in a vehicle and a new battery through a communication module respectively, invoking a matched protocol to respectively read parameter information of the old battery in the vehicle and parameter information of the new battery by the human-machine interaction system; automatically generating a pairing repair scheme by the human-machine interaction system according to the read parameter information of the old battery in the vehicle and the parameter information of the new battery, and performing pairing repair for the new battery according to the pairing repair scheme. The invention also provides a system corresponding to the method. The intelligent battery pairing repair method of the invention has the advantages of automatically identifying communication interfaces and protocols of various batteries, automatically generating the pairing repair scheme, and allowing the pairing repair for the battery more intelligent and convenient.

Description

technical field [0001] The invention relates to the field of batteries, in particular to an intelligent battery pairing repair method and system. Background technique [0002] At present, new energy power lithium battery vehicles are developing at a high speed. The car battery is composed of multiple battery modules. During the use of the vehicle, the power battery will inevitably fail, such as a lot of power reduction, some batteries are damaged, circuit board components Damage, etc., at this time, the car battery needs to be replaced or repaired, and the cost of replacing the entire car battery is very expensive. Therefore, the most economical maintenance method is: only replace the problematic module, but the capacity of the new module may not exactly match the battery on the original car. In this case, it is necessary to pair the new module with the original battery on the car. . [0003] In the prior art, when performing pairing operations on devices, data such as cel...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when performing pairing operations on devices, data such as cell voltage and cell temperature of the battery module are collected through the wiring harness, which makes it necessary to make according to the cell sampling port of the battery module during specific implementation. Different sampling harnesses; at the same time, with the increase in the types of cell sampling ports, more types of sampling harnesses are required, and as the number of cells increases, more wires need to be used, which makes the entire production process very complicated

[0004] In addition, the existing technology still has the following defects when performing pairing operations on devices: 1. It is necessary to manually set the cut-off conditions of the paired cell voltage, charge and discharge current, etc., which is complicated and inefficient to operate; 2. When the battery sampling interface of the module is docked, it is necessary to disassemble the battery waterproof layer first, which will not only consume more time, but also damage the waterproof seal; 3. Use the method of emptying the battery to calculate the capacity of the old battery on the car , this process is time-consuming; at the same time, in order to improve the pairing efficiency, an additional module is needed to charge and discharge the old battery on the car, resulting in high cost
