Output port overload

Part of the certification projects	Requirements for output port overload testing
UL Certification	Each power output pin of the output port should be overloaded as per the following regulations. Charge the built-in battery of the battery pack to a sufficient level according to the manufacturer's specifications. Cover the battery with a layer of gauze and place it on a softwood board. Cover the softwood board with a thin sheet of paper. Then load each power output pin of the output port to draw the maximum current, for at least 1 hour. The maximum current should be slightly lower than the trip point of any protection device, which is considered to be 110% of its rated current. Result: After completion, the gauze and paper should be intact.
CQC Certification	After the battery is fully charged according to the charging procedure specified by the manufacturer, it is charged at a constant current of 1.5 times the overcurrent protection current. The cycle test is conducted 500 times. Result: No fire, no explosion, no leakage.
