IEC 62660-2 Mechanical Test of EV Lithium Battery -Vibration Test

Vibration

1. Adjust the state of charge for BEV application batteries to 100%, and HEV application batteries to 80%;

2. Perform random vibration test, each battery surface test time is 8 hours;

3. The value of acceleration is 27.8m/s^2, and the corresponding value of PSD (Power Spectrum Density) and frequency is shown in the figure below. The maximum frequency is 2000 Hz.

The working principle of the electromagnetic vibration exciter is similar to a loudspeaker whereby electricalconductor is moved by the action of electromagnetic force in the magnetic field. The force to accelerate the moving part is generated by the balance between driving current and magnetic flux. Therefore, by controlling the driving current, one can control the vibration generator.

Sanwood The low-thrust series electric vibration test system ranges from 1KN-20KN. The main features include high frequency of moving coils, excellent indicators, high reliability, and easy operation. Very suitable for Lithium Battery,single batteries battery pack and other electronic products.

Test results should be measured and recorded:

1 The voltage and capacity of the battery before the test and the voltage and capacity of the battery after the test;

2 Record the status of the battery after testing against the following standards
