International Standard Testing Procedures
External Short Circuit at Normal Temperature
Fully charge battery per specifications and place at 20℃±5. After temperature stabilization and 30-minute placement, connect opposite and negative poles with wire ensuring 80mΩ±20mΩ external resistance. Monitor temperature changes. Test concludes when temperature drops 20% from peak or after 24 hours. Qualified batteries show no fire/explosion and remain below 150℃.
Temperature coefficient of wire resistivity should be less than 5x10¯³℃¯¹ (e.g., constantan wire).
High Temperature External Short Circuit
Follow same procedure as normal temperature test but conduct at 55℃±5. Same qualification criteria apply - no fire/explosion and temperature below 150℃.
Short Circuit Function under Short Circuit Protection
Conduct 500-cycle test sequence: short circuit opposite and negative poles with output terminal in protection circuit, wait 1 minute after protection activation. Maintain 80mΩ±20mΩ external resistance throughout. Device must function properly in each cycle.
