1 Scope of Application

1.1 Applicable standard

The battery short-circuit test chamber is suitable for lithium primary batteries and other primary batteries, as well as lithium-ion batteries (used in digital electronic products such as mobile phones, laptops, cameras, etc.), nickel hydrogen, nickel cadmium, and lead-acid batteries (used in products such as power tools, toys, electric bicycles, etc.), according to standardsGB8897.4-2002TheGB/T18287-2000TheIEC60086-4: 2000TheIEC62133: 2002TheQC/T 743-2006TheUL1642: 2006TheSN/T1413-2004TheSN/T1414.3-2004TheGB31241-2022TheGB/T 36972-2018Conduct external short-circuit tests in accordance with the relevant requirements.

1.2 Test requirements

In the above standards, forhigh temperatureThe requirements for external short-circuit testing are slightly different, and the battery short-circuit test box meets all of the following test requirements:

1）The battery is（57±4）After reaching temperature equilibrium in an environment of ℃, withstand the total resistance of the external circuit at the same temperature0.1The short circuit of Ω continues until the temperature of the battery casing drops back to（57±4）After ℃, continue1More than hours.

2）A fully charged battery or battery pack（20±5）℃ or（57±4）℃，Relative humidity not exceeding75%Under the environmental conditions,The total resistance of the external circuit between the positive and negative poles of the battery or battery pack0.1Short circuit of Ω, short circuit test continues24Hours, or when the temperature of the battery casing drops below the peak value20%At the end of the experiment (monitored by thermocouples), take the test results with a shorter time.
