6. Mechanical and safety characteristics
4 Crush Test
The charged cell shall be crushed between two flat
surfaces ,the force for the crushing is to be applied
by a hydraulic ram with a 32mm diameter
piston ,the crush is to be continued until a pressure
reading of 17.2 Mpa is reached on the hydraulic
ram ,applied force of 13KN ,once the maximum
pressure has been obtained it is to be released
No fire and no exploding
5 Hot Oven
The charged cell is to be heated in a gravity
convection or circulating air oven, the oven
temperature is to be raised with a rate of 5 ? per
minute to 130±2?before the test is discontinued
No fire and no exploding
6 Short Circuit
The cell is to be short-circuited by a cooper wire
have a resistance about 0.1ohm between the
positive and negative terminals
Protected
7 Over Charge The cell is charged using a constant current of 4A
until the current drop to 0A Protected
