BMS (battery management system) testing monitoring system and method

Abstract

The invention discloses a BMS testing monitoring system. The BMS testing monitoring system and method comprises an upper computer, a single voltage simulating unit, a temperature simulating unit, an insulating resistance simulating unit, a total current simulating unit, a digital quantity simulating unit and an overvoltage and undervoltage detecting unit. The invention also discloses a BMS testing monitoring method. The method comprises the steps of single voltage testing, temperature testing, digital quantity O / I (output / input) testing, battery set insulating resistance testing, system overvoltage testing and total current simulative testing. The BMS testing monitoring system and method can test the comprehensive performance and the functions of a BMS and accordingly improve the efficiency. The reasonable matching of a battery set and the BMS can greatly improve uniformity and security of the battery set, accordingly improve the comprehensive performance and the time and the capacity of energy output and storage of the battery set, and further promote industrialization of new energy vehicles and energy storage systems.

Description

technical field [0001] The invention relates to the field of battery management, in particular to a BMS verification monitoring system. It is suitable for the detection and verification of the battery management system BMS in the fields of electric vehicles, energy storage power stations and special power supplies, so as to provide a basis and guarantee for selecting a suitable battery management system for the battery pack and improving the consistency and safety of the battery pack. Background technique [0002] With the vigorous promotion and development of new energy and electric vehicles in my country, the consistency and safety of power battery packs are becoming more and more important, and they are also the key to industrialization. Due to the influence of many factors such as materials, processing technology, equipment, production process, electrochemical characteristics of the battery itself, and the use environment, the consistency and safety of batteries, especia...

Problems solved by technology

But now BMS products are difficult to provide customized services for battery packs with different materials, different uses, and different characteristics. Most of the BMS products sold on the market have basically the same functions, and there are few BMS systems that perform SOC estimation and safety warnings for specific batteries. customized services

When the battery factory chooses BMS, it is often unclear whether the BMS product is suitable for the corresponding battery, resulting in waste and unreasonable product system matching
