With the development of industrial automation, AGV (automatic guided vehicle) is widely used as an important logistics equipment, and one of its core components is battery pack. In order to ensure the reliable operation of AGVs, the reliability test of battery pack is particularly important. This paper will analyze the reliability test project scheme of 48-80V and 10-200 Ah industrial AGV lithium battery pack (including BMS) in detail, including test purpose, sample planning, test matrix, test methods and criteria, data collection and milestone setting.

I. Test purpose:

1. evaluate the reliability and stability of battery pack under actual working conditions.
2. Found faults and problems that may occur during prolonged use of battery pack.
3. Provides reliable data support for improving performance and lifetime by battery pack.

II. Sample planning:

according to the specifications of 48-80V and 10-200 Ah industrial AGV lithium battery pack, select representative battery samples for testing to ensure the reliability and representativeness of the test results.

3. Test matrix:

1. cycle Life Test: SimulationBattery pack test the cycle life and attenuation during the cyclic charging and discharging process in actual use.
2. High and low temperature test: test battery pack performance under extreme temperature conditions and evaluate its reliability under different temperature environments.
3. Vibration Test: simulate the vibration of AGV under different road conditions and test the stability of battery pack in vibration environment.
4. Test data record: Record battery pack data in various tests, including voltage, current, temperature and other parameters.

IV. Test methods and judgment:

1. cycle Life Test: observe the changes of battery pack voltage, capacity and other parameters according to the set number of charge and discharge cycles and current, and judge the performance attenuation.
2. High and low temperature test: put battery pack under different temperature environments to test its discharge performance and cycle life under extreme temperature conditions.
3. Vibration Test: vibrating table is used to simulate the vibration of the AGV during driving, observe whether the appearance of the battery pack is damaged, whether the battery parameters are abnormal, and judge the stability under the vibration environment.

V. Data and milestones:

1. data acquisition: collect and record the data of battery pack in various tests in real time, including parameters such as voltage, current, temperature, cycle times, etc.
2. Milestone setting: according to the data changes and performance performance in the test, set milestones at different stages to evaluate the reliability and stability of battery pack. </span>
