The Testing Method Of Power Battery Pack

The battery pack body test is generally conducted at the DV / PV (design verification / production verification) stage, the purpose is to verify whether the design / production of the battery pack meets the design requirements. It includes temperature test, mechanical test, external environment simulation test, low voltage electrical test, electromagnetic compatibility test, electrical safety test, battery performance test, abuse test test, etc. Because everyone is more concerned about battery safety, here is a brief introduction to the test method of the battery pack test:

1) Acupuncture test

Simulate the scene when the battery is pierced by a sharp object, because the penetration of foreign objects may cause an internal short circuit, the test requires no fire or explosion

2) Salt water immersion

5% salt water immersion test for a long time, the battery function is normal

Immersed in 1 meter of water for half an hour without damage (Right Energy's waterproof battery is IP7).

3) External fire

The fire at 590 degrees Celsius lasted 130 seconds. The battery did not explode, catch fire, burn and there was no flame residue.

4) Drop

1m height free fall on the steel plate, the battery shell is fully functional

5) Vibration test

High frequency vibration simulation test requires the battery pack to function normally. Colleagues who make battery packs should know that this is also difficult to pass.
