1、 Vibration:
1.01. Test requirements: The tested battery should withstand a simple harmonic vibration with an amplitude of 0.8mm (a large displacement of 1.6mm)
. The frequency varies at a rate of 1HZ/min within the range of 10HZ~55HZ, and recovers after
90min~100min. Perform
tests on the three mutually perpendicular axes of the battery. For test cells with only two symmetrical axes, perform
tests on the two perpendicular axes of the battery. Both batteries that have not been discharged and fully discharged should be tested
1.02. Test results: No mass loss, deformation, leakage, discharge, explosion, or ignition
2. Thermal shock:
2.01. Test requirements: The test battery should be placed at a temperature of (75 ± 2) ℃ for 48 hours, followed by a temperature of (-20 ± 2) ℃ for 6 hours, and then at room temperature for at least 24 hours. The conversion time between different temperatures is 5 minutes. During the test, appropriate protective measures should be taken to protect the battery from the influence of condensation water during the process of recovering to room temperature after low-temperature storage
2.02. Test results: No liquid leakage, no discharge, no explosion, no fire 3. High temperature:
3.01. Test requirements: The test battery should be placed at (100 ± 2) ℃ for 5 hours, followed by (20 ± 2) ℃ for 8 hours; Another experiment involves placing the tested battery at (60 ± 2) ℃ for 30 days and then at (20 ± 2) ℃ for 8 hours
3.02. Test results: No discharge, explosion, or ignition
4. High simulation:
4.01. Test conditions: Place the test battery in an environment with a pressure of 11.6pa (kPa) or lower and a temperature of (20 ± 5) ℃ for at least 6 hours.
4.02. Test results: No mass loss, deformation, leakage, discharge, explosion, or ignition V. External Short Circuit:
5.01. Test Requirements:
A. The battery should reach temperature equilibrium in an environment of (55 ± 2) ℃ and withstand a short circuit with a total resistance of less than 0.1 ohms in the external circuit at the same temperature. The short circuit should continue until the temperature of the battery shell drops back to (55 ± 2) ℃, and continue for more than 1 hour B. Conduct this test using batteries that have undergone vibration and impact tests C. Additionally, use batteries that have undergone high-altitude simulation tests and thermal shock tests to conduct this test
5.02. Test results: No explosion or ignition 6. Drop:
6.01. Test requirements: Undischarged batteries should drop from a height of 1m onto a concrete surface. Each tested battery should drop six times, one on each of the six faces of the prismatic battery, and two on each of the three axes of the circular battery. Then, the tested battery should be placed for 1 hour
6.02. Test results: No discharge, explosion, or ignition
