Main items and indicators of ul1642 battery test

short circuit test at room temperature (5) at 60 ℃ (5)

the positive and negative electrodes covering an area of 465 Mu are short circuited with wires with an internal resistance of 100m Ω, the battery is discharged until it catches fire or explodes, or until the battery is completely discharged. Any one of the measures, the shell temperature drops to room temperature and stops

no explosion Adler believes that it does not catch fire, and the shell or battery shell temperature does not exceed 150 ℃

overcharge (5)

the fully discharged sample is inversely connected with the DC power supply, charged with 3 times the current of IC, charged for TC hours, IC is equal to the current specified by the manufacturer, TC is equal to 2.5c/3 (IC)

no explosion, no fire, no night leakage

reverse charging (5)

charge the fully discharged battery with 3C current in reverse DC for 48 hours

without explosion, fire and night leakage

mandatory discharge (5)

it is applicable to the cell working in the way of battery pack. Connect the fully discharged cell and the charged cell in series and short circuit until the fire or explosion or the temperature drops to room temperature.

no explosion, no fire.

mechanical abuse test compression test (5) (be-6045) impact test (5) (be-5066) impact test (5)

flat compression, maximum pressure 17.2mp, pressure 13kn

no explosion, No fire

9.1 ± 0.46kg hammer impacts the battery placed on the battery from a height of 610 ± 25mm Ф The 15.8mm round bar

does not explode and catch fire

for the initial 3MS, the minimum average acceleration is 75g (G is the local acceleration), and the peak acceleration should be between 125g and 175g. Impact test shall be carried out in three directions perpendicular to each other of the battery

no fire, no explosion, no leakage, no night

vibration test (5)

single amplitude 0.8mm in the range of 90 ~ 100min, 10 ~ 55 ~ 10Hz, linear sweep frequency vibration of 1hz/min. Vibration test should be carried out in the three directions perpendicular to each other of the battery

the sample does not explode or catch fire, does not smoke and does not leak liquid

heat abuse test heating test (5) spray test (5)

heat it to 150 ℃ every minute and keep it warm for 10min

do not explode and do not catch fire

place the battery on an iron (diameter 0.43mm) with an eye of 1.27mm, the flame furnace is 38.1mm from the bottom of the iron, and a 914mm is placed vertically at a lateral distance of 0.91M from the heating center × 914mm flat plate is paved with 4 layers of asbestos cloth with an area density of g/m2. The safety valve of the battery is always facing the asbestos plate. After the explosion is sprayed, the experiment ends

environmental test (be-th Series) thermal cycle test (5) low pressure test (5)

raise the temperature to 70 ℃ for 4H within 30min, lower the temperature to 20 ℃ for 2h within 30min, lower the temperature to 40 ℃ for 4H within 30min, and raise the temperature to 20 ℃ within 30min. This cycle again for 9 times, After storage for 7 days, observe

no fire, no explosion, no leakage, no leakage at night

Room Temperature 11.6kpa storage for 6h

no fire, no explosion, no leakage by increasing the tool back angle value, the feed thrust leakage can be effectively reduced, no leakage at night
