LV 124 Test Standard Should Be Perform (EV Electric Vehicle Battery)

Electric and Electronic Components in Passenger Cars up to 3.5 T - General Requirements , Test Conditions and Tests

Dust Test

This test simulates the dust load of the component during vehicle operation.

This test shall be carried out in accordance with ISO 20653 with the following parameters

Protection against water (IPX0 to IPX6K)

This test simulates the exposure of the component to water.

This test is intended to verify the function of the component. Eg, when exposed to condensation water, rain or splash water.

This test shall be carried out in accordance with ISO 20653 with the following parameters

High pressure/steam- Jet cleaning

This test simulate the exposure of the component to water during vehicle cleaning

The test shall be carried out in accordance with ISO 20653 with following parameters

Thermal Shock with splash water

This test simulate the exposure of the component to splash water as it occurs when driving through puddles.

The test is intended to verifyb the function of the component when exposed to rapid cooling by means of water.

Test procedure	Heating of DUT to test temperature.This is followed by the cyclic splashing of the DUT as per figure 30.The DUT shall be splashed over its entire width
Cycle duration	30 minutes
Test temperature	T (max)
Splash water temperature	0 ~ +4 ℃
Splash duration	3 seconds
Water flow	3 to 4 liters per splash/ nozzle
Distance of nozzle to DUT	300 to 350mm
Number of cycles	100
Number of DUTs	6

When performing the test, the installation position of the component in the vehicle shall be simulated

Thermal Shock Immersion

This test simulates the exposure of the component when immersed in water.

The test is intended to verify the function of the component when subjected to immediate cooling by means of immersion of the heated component.

Test procedure	Heat the DUT to test temperature Hold at test temperature until complete thermal equilibrium is reached (see section 5.4) and then for 15min more. Then fully immerse the DUT for a maximum of 5s into the test fluid such that all sides of the DUT are surrounded by at least 25mm of the test fluid
Test medium	0℃ cold, 5% salt water solution
Immersion time	5 min
Number of cycles	20
Number of DUTs	6

Corrosion test with flow of mixed gas

The test simulates the influence of corrosive gases on the component, particularly its plug contacts and switches.

The test in intended to verify the resistance of the component to faults such as corrosion and component damages.

This test shall be carried out in accordance with DIN EN 600068-2-60 method 4 with following parameters:

Operating mode of DUT	Operating mode I.b
Temperature	T(RT)
Humidity	75%
Corrosive gas concentration	So2	0.2ppm
	H2S	0.01ppm
	No2	0.2ppm
	Cl2	0.01ppm
Test duration	21 days
Number of DUTs	6
