Two sides of  X,Y,Z directions each (total 6 times)  After the drop test, discharge the battery 0.5C to 3.0V  Then charge it 0.5C to full capacity. Continue the test   within 3 times the battery should reach the target once   Discharging time ≥102 Min   No erosion, no explosion,no fire,no leakage

Safety Performance

Overcharge protection test After standard charging. Apply a 7.4V stable Voltage and  1C stable current to the battery for 8 hours No fire, no explosion
Over discharge protection test After discharged to the cut-off voltage,the battery shall be  subjected to a short-circuit condition with a load of  resistance less than 30Ω for 24 hours No fire, no explosion
Short circuiting protection test After standard charging,the battery shall be subjected to a  short-circuit condition with a wire of resistance less than  100mΩ for 1 hour. Cut off the circuit, Charge the battery  with constant current at 1.0C for 5s No fire, no explosion, Voltage≥3.7V
Impact Test  After standard charge,Place the battery on a flat surface.  A 9.1 kg article is to be dropped from a height of 100cm  onto the sample. The battery is allowed to transform No fire, no explosion
 Heating Test After standard charging,a battery is to be heated in an  oven convection or circulating air oven. The temperature of  the oven is to be raised at a rate of 5±2℃/min to a  temperature of 130±2℃ and last for 30 minutes. No fire, no explosion
Over charge  After standard charging, put the battery in fume hood. Add  constant voltage & current 4.8V 3C to the battery. Charging  it until the battery reaches 4.8V, charging current decreases  to almost 0A. Record the temperature curve of the battery.  When the battery temperature decreases to about 10℃  lower after reaching the peak temperature. End the test. This test is performed without PCM  No fire, no explosion
Short circuiting test After standard charging, put the battery in fume hood.  Connect the Negative Pole and Positive pole directly. (the  wire’s resistance should below 50mΩ. Record the battery’s  temperature curve during the test. When the battery  temperature decreases to about 10℃ lower after reaching  the peak temperature. End the test.  This test is performed without PCM
