GB/T 36276 and UL 1973 are two important test standards related to energy storage batteries. These test standards cover the evaluation of the performance, safety and reliability of energy storage batteries, which are of great significance to ensure the quality and safety of energy storage battery products. This article will discuss the main contents and test requirements of these two test standards.

GB/T 36276 Test

GB/T 36276 is the "lithium-ion energy storage battery specification" issued by the National Standardization Committee of China, which contains a series of performance and safety requirements for energy storage battery products. The following are the main contents of GB/T 36276 test:

1. Safety performance test

including short circuit test, overcharge test, over discharge test, etc., to evaluate the safety performance of energy storage battery in abnormal conditions, to ensure that it will not explode, fire and other safety accidents.

2. Cycle life test

through the cycle charge and discharge test of the energy storage battery, its cycle life and charge and discharge performance are evaluated to determine its stability and reliability in actual use.

3. Charging performance test

the charging performance of the energy storage battery is tested, including the evaluation of charging efficiency, charging time, constant voltage charging, constant current charging and other parameters, to ensure that its performance in the charging process meets the requirements.

4. Discharge performance test

the discharge performance of the energy storage battery is tested, including the evaluation of discharge capacity, discharge time, discharge curve and other parameters, to ensure that its performance in the discharge process meets the requirements.

UL 1973 Test

UL 1973 is the "Energy Storage System, Power Supply Device and Battery Test Standard" issued by UL, a safety certification body in the United States. The following are the main contents of the UL 1973 test:

1. Temperature cycle test

the performance and reliability of energy storage batteries under different temperature conditions are evaluated by temperature cycle tests to ensure their safety and stability in extreme temperature environments.

2. Short circuit test

the short-circuit test of the energy storage battery is carried out to evaluate its safety performance in the case of short circuit, so as to ensure that it will not have safety problems such as overheating and explosion.

3. Thermal runaway test

through the thermal runaway test of the energy storage battery, its safety performance in the case of overheating is evaluated to ensure its stability and safety in high temperature environment.

4. Vibration test

vibration tests are performed on energy storage batteries to evaluate their performance and reliability in vibration environments to ensure that they will not be damaged or malfunctioning during transportation and use.

GB/T 36276 and UL 1973 are two important test standards that cover the performance and safety evaluation of energy storage batteries. By testing in strict accordance with these test standards, the performance and safety of energy storage battery products can be comprehensively evaluated, and an important reference for product improvement and optimization can be provided.
