To ensure that LiBs reach the required safety norms and to reduce the risk of TR, battery safety standards have been developed. They facilitate and regulate the usage of LiBs available on the market by proposing standardised settings and tests.
This overview of currently available safety standards for batteries for stationary battery energy storage systems shows that a number of standards exist that include some of the safety tests required by the Regulation concerning batteries and waste batteries, forming a good basis for the development of the regulatory tests.
Overcharging and thermal abuse testing remains the most documented battery safety tests in the literature and the most observed reasons for battery safety accidents.
“This test shall evaluate the safety performance of a battery in internal short-circuit situations. The occurrence of internal short circuits, one of the main concerns for battery manufacturers, potentially leads to venting, thermal runaway, and sparking which can ignite the electrolyte vapours escaping from the cell.
Most of the standards require the test at ambient temperatures between 20 and 25°C. Only IEC 62984-2:2020 and UL 1973:2020 do not specify the test temperature. The overcharging voltage varies from 10 % (IEC 62619:2022, IEC 62984-2:2020, UL 1973:2020 and GB 40165-2021) to 150 % (IEC 63115-2:2021) exceeding the upper limit charging voltage.
Indeed, when electrochemical systems such as LiBs operate outside their normal range of operation, thermal runaway (TR) occurs leading to safety hazards that include fire, smoke and in some cases explosion. In battery safety research, TR is the major scientific problem and battery safety testing is the key to helping reduce the TR threat.
