System and method for testing comprehensive working condition of power battery and battery testing system

Abstract

The invention discloses a system and method for testing a comprehensive working condition of a power battery and a battery testing system. The system for testing the comprehensive working condition comprises a processor, a working condition acquisition device and an instruction acquisition device. The processor is used for being connected with a battery controller and a charging and discharging device in a battery system separately and controlling the battery controller and the charging and discharging device to conduct charging and discharging testing of the comprehensive working condition onthe power battery in the battery system according to a preset comprehensive working condition file and a testing control instruction; the working condition acquisition device is connected with the processor and used for acquiring the preset comprehensive working condition file; the instruction acquisition device connected with the processor is used for acquiring a testing control instruction. According to the testing system and method, the comprehensive working condition of the power battery is tested, the system is simple in connection structure, suitable for various charging and dischargingdevices and power batteries of various types and wide in application range, and compared with upgrading, reconstruction and maintenance cost of the charging and discharging device, the system is lowin reconstruction cost and has a better market prospect.

Description

technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a comprehensive working condition testing system and method of a power battery and a battery testing system. Background technique [0002] With the development of science and technology in modern society, the use of new energy vehicles is becoming more and more extensive. As the core component of new energy vehicles, the power battery assembly is particularly important to fully verify its performance, reliability and other indicators. With the development of vehicle power battery testing technology, the battery bench test is getting closer to the actual use of the user. It is not only necessary to test the parameters of the battery itself, but also to simulate the data parameters of the corresponding vehicle. The test conditions have changed from the early tens of step cycles to hundreds of thousands of step cycles. The test content has developed from early battery c...

AI Technical Summary

Problems solved by technology

[0003] At present, battery testing equipment is mainly charging and discharging equipment. Although the hardware conditions of the charging and discharging equipment can basically meet the requirements of use, the software functions of the charging and discharging equipment are relatively simple, usually only including step-by-step constant current / voltage charging, data recording, etc. It is not enough to support increasingly complex test methods; and due to the complex structure of charging and discharging equipment, the cost of upgrading and repairing is very high
