Higher than 80% of the Initial Capacity |
Impact Test | A cell is to be placed on the impact flat. A 56mm diameter bar is inlayed into the bottom, A 10 kg weight is to be dropped from a height of 1m onto the cell, the distortion is allowed. | No explosion, No fire. |
Forced Discharge | Discharge at a current of 1C for 2.5h. | No explosion, No fire. |
Nail Pricking | Prick through the sample battery with a nail having a diameter of 3mm and remain 2h. | No explosion, No fire. |
Vibration test | After standard charge, the battery is to be tested as following conditions: Amplitude: 0.19mm Frequency: 10~55Hz (sweep: 1Hz/min) Direction: X/Y/Z axis for 30min. The battery is to be tested in three mutually perpendicular to each axis. |
No fire, no explosion, no smoking. |
Drop Test | Drop the battery in the shipment condition (full- charge) from 1m height onto 18~20 mm or thicker concrete with p-tile on it 1 times each of obverse and inverse directions at 25±2℃ | No fire, no explosion, no smoking |
Constant Humidity and Temperature Characteristics | Under the temperature of 20±5℃, after charging the battery with 0.2C, then put the battery into the constant temperature and humidity oven with 55±2℃ and 90~95% for 48h, the battery should be no obvious deformation, leakage, rust, smoking and explosion. After testing take out the battery then rest for 2h under the temperature of 20±5℃, discharge with 1C to 3.0V. | discharge capacity≥60% C5 |
Short-Circuit Test | After standard charge, the battery is to be short-circuited by connecting the positive and negative terminals of the battery with copper wire having a maximum resistance load of 0.1Ω. | No explosion, no fire. The temperature of the exterior cell casing shall not exceed 160℃. |
Heating Test | A battery is to be heated in a gravity 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℃ at which temperature the oven is to remain for 30 minutes before the test is discontinued. | No explosion, no fire. |
Abnormal Charging Test | After standard charge, the battery is subjected to a charging current by connecting it to a dc-power supply. The beginning current is 3.0C, which is to be obtained by connecting a resistor of specified size and rating in series with the battery; the voltage of the dc-power supply is 4.6V. The test time is 2.5 hours. | No explosion, no fire. |
Over-discharge Test | The fully discharged cell is continually discharged for 24h with the (30×n) Ω load at 23±2℃. | No explosion, no fire. |
High Temperature Characteristics |
Within 2h leave the battery in Constant Temperature & Constant Humidity Box which temperature is 55±2℃ after fully charge, discharge at 1C to 3.0V. The discharge time is required ≥51min | no deformation and smoking |
Low Temperature Characteristics |
After fully charge, leave the battery in Constant temperature & constant Humidity box which temperature is -10±2℃ for 16-24h, discharge at 0.2C to 3.0V. The discharge time is required ≥3h | no deformation and smoking |
