Why does lithium battery pack need aging test?
Lithium battery pack aging test is an indispensable procedure in the production process of lithium batteries. It is to better evaluate battery life and performance attenuation, so as to ensure the stability and reliability of factory batteries. What is battery aging test ? The battery aging test is a test that simulates the actual use of the battery, performs charge and discharge cycles on the battery, and records the performance of the battery. This kind of test is generally divided into normal temperature aging and high temperature aging. As the name implies, the battery is placed under normal temperature and high temperature conditions for charge and discharge cycle testing. In the battery aging test, the general test indicators involve the internal resistance, voltage and capacity of the battery, and these data are of great significance for the evaluation of the battery. The purpose of the aging test The purpose of aging test can be mainly explained from two aspects: enterprise and
