7.1.4 Vibration test

battery vibration frequency is to be varied at the rate of 1 hertz per minute between 10 and 55 hertz, and return in not less than 90 or more than 100 minutes. test in three mutually perpendicular directions

Pass/Fail criteria: The battery samples shall be no explosion or catch fire. In addition, the samples shall no vent or leakage.

7.2 Safety test

7.2.1 heating

Battery is heated in a gravity convection or circulating air oven. The temperature of the oven is to be raised at a rate of 5±3℃ per minute to a temperature of 130±2℃ and remain for 10 minutes at that temperature before the test is discontinued.

Pass/Fail criteria: The battery samples shall be no explosion or catch fire.

7.2.2 Impact

A test sample cell was placed on a flat surface. A 5/8 in. (15.8 mm) diameter steel bar was placed across the center of the sample. The length of the bar should be at least as long as the width of the sample. A 20 pound (9.1 kg) weight was dropped from a height of 24 ± 1 in. (610 ± 25 mm) on to the sample.

Pass/Fail criteria: The samples shall not explode or catch fire.

7.2.3Crush test

A cell was crushed between two flat hard surfaces (i.e. steel). The crushing was continued until a force of 3000 pounds (13kN±0.78kN) was applied by hydraulic piston with a diameter of 32mm. press continue until pressure reach up to 17.2Mpa. Once the maximum pressure was obtained, it was released.

Pass/Fail criteria: The battery samples shall be no explosion or catch fire.

7.2.4 forced discharging

a completely discharged cell is to be force-discharged by connecting it in series with fully charged cells of the same kind. The number of fully charged cells to be connected in series with the discharged cell is to equal the maximum number less one of the cells to be covered for series use, the circuit load resistance less than0.1Ω. The sample is to discharge until a fire or explosion is obtained, or until it has reached a completely discharge state of less than 0.2V and battery case temperature has returned to ±10℃(+18ºF) of ambient temperature.

Pass/Fail criteria:The samples shall be no explosion or catch fire.

7.2.5 External Short-circuit

Connect the battery positive and negative terminal with Cu wire(internal resistance ＜ 0.1 ohm), battery was discharged until a fire or explosion was obtained, or until it had reached a completely discharged and the cell case temperature had returned to ambient temperature.

Pass/Fail criteria: The battery samples shall be no explosion or catch fire.

7.2.6 forced recharging

Tested battery is subjected to a charging current of three times of the current specified by the manufacturer by connecting dc-power. The specified charging current is to be obtained by connecting a resistor of specified size and value.

The test time is calculated from the formula:

T_c=2.5*C/(3*I_c)

In which

T_c——charge time, hour, Tc≥7Hour；

C——Nominal capacity, Ah；

I_c——Max. charging current,mA. ER18505 maximum charge current is 0.015A.

Pass/Fail criteria:The samples shall be no explosion or catch fire.
