Project Standard Adoption of the
Short circuit External short circuit the battery 10min, external line resistance should be less than 5M. The battery should be no explosion, no fire Pass
Overcharge At 23 ± 5 ℃ condition, battery 1C charge to 15V, and constant voltage 15V current fall close to 0A, monitor the battery temperature, when the temperature drops below the peak of about 10℃, to stop the tests. Battery should not fire and not explode. Pass
Over discharge At 23 ± 5 ℃ condition according to standard discharge requirements after discharge to voltage, external 30Ω load discharged 24 hours. batteries should be no explosion, no fire, no leakage. Pass
Heating Battery within 85℃ ± 2℃ thermostat and thermal insulation 120min. The battery should be no explosion, no fire Pass
Acupuncture Φ 3mm~ 8mm high temperature wire, at a 10-40mm/s speed, perpendicular to the direction of the battery plates, at least throughout the cell (the wire stays in the cell). Battery explosion, no fire Pass
Extrusion Orientation to perpendicular to the battery press, squeeze to the battery module 85% of the original size, keep 5min and squeeze again to the battery module 50% of the original size. Pass
