Fig.6 Diagram of the Extrusion Device
3.17.5 Drop Test
At the ambient temperature of25°C±2℃,charge the cell according to (3.8).Drop the cell from a
height of 1.5 meter to the concrete floor with its positive or negative terminals downwards.Then
observe it for 1 hour.(Refer to GB/T
36276-2018 Lithium ion battery for electrical energy storage)
3.17.6 Low Pressure Test
At the ambient temperature of 25°C±2℃,charge the cell according to(3.8),and then
install the test clamp according to(3.3.1).Put the cell into the low-pressure box,adjust the
pressure to 11.6 kPa,keep the temperature at 25°C±2℃,and rest for 6 h.Then observe for 1
hour (Refer to GB/T 36276-2018 Lithium ion battery for electrical
energy storage)
3.17.7 Heating Test(130℃)
At the ambient temperature of 25°C±2°C,charge the cell according to(3.8),and then
install the test clamp according to(3.3.1).Put the cell into the temperature box,rise the temperature
to 130°C±2℃ at a rate of 5°C/min,keep the temperature for 30 min and then stop heating.Observe
for 1 hour (Refer to GB/T 36276-2018 Lithium ion battery
for electrical energy storage)
