Overcharge testing simulates a pack being left on a defective charger for 24 hours and then placed in the shipping channel for seven days (there is a seven day wait period after overcharge exposure). This is a test of the pack''s safety circuit design margin to protect the cells against long-duration exposure to elevated voltage and current.

Overcharge is a hazardous abuse condition that has dominant influences on cell performance and safety. This work, for the first time, comprehensively investigates the impact of different overcharge degrees on degradation and thermal runaway behavior of lithium-ion batteries. The results indicate that single overcharge has little influence on …
We cover a wide range of lithium-ion battery testing standards in our battery testing laboratories. We are able to conduct battery tests for the United Nations requirements (UN 38.3) as well as several safety standards such as IEC 62133, IEC 62619 and UL 1642 and performance standards like IEC 61960-3.
