6 FAQs about [Energy storage battery short circuit test system]
What is the external short-circuit test for battery cells?
The external short-circuit test for the battery cells is also performed depending on two types of battery cells. The test is classified with NMC prismatic and pouch-type batteries in series, and the test device for the external short circuit is configured as shown in Figure 3.
What type of batteries are used in a short-circuit test?
The modules for the external short-circuit test are mainly composed of two types of battery cells. Here, among the NMC series of batteries, which is the most widely used type in medium and large batteries on the domestic market, the prismatic and pouch-types are adopted in the test.
What are the standards for energy storage batteries?
In the standards for energy storage batteries, IEC 62619-2022 [ 70] requires that sample cells are charged with a constant current equal to the maximum specified charging current of the battery system until the voltage reaches the maximum voltage value that is possible under the condition where the original charging control does not work [ 95 ].
What is external short circuit test?
External Short Circuit Test The external short circuit test is used to evaluate the bearing capacity of the battery after the external short circuit [ 98, 99, 100 ]. ISO-12405-1-2011 [ 46] selects 100 mΩ conductors for the external short circuit and lasts for 10 min, while ISO-12405-2-2012 [ 64] selects 20 mΩ conductors [ 101 ].
What is a long-time battery test?
The long-time test refers to keeping the battery short-circuited until the battery temperature drops from the highest temperature by 20% of the maximum temperature rise according to the IEC62133 standard.
Should the external short-circuit resistance of EV batteries be lowered?
(6) Based on the proposed test results, it is recommended that the external short-circuit resistance should be lowered to the standards for EV batteries in order to achieve a meaningful assessment of the battery safety, as the external short-circuit resistance of ESS batteries in the current standards is too high.
