Standard: When the ambient temperature is (23±2)°C and the relative humidity is 45% to 75%, the insulation resistance between the positive (E), negative (F) output and the body (shell) is ≥1000MΩ. When the humidity is 90% to 95%, the insulation resistance is ≥20MΩ.
Positive and negative insulation performance test of on-board charger
4) DC-DC converter positive and negative insulation performance test: disconnect the negative pole of the low-voltage battery, unplug the high-voltage accessory harness plug of the high-voltage box, connect the black test lead of the insulation resistance meter to the vehicle body, and measure the high-voltage accessory harness plug of the high-voltage box one by one with the red test lead Positive and negative electrodes.
Standard: When the ambient temperature is (23±2)°C and the relative humidity is 80% to 90%, the insulation resistance between the positive (A), negative (G) output and the body (shell) is ≥1000MΩ. When the ambient temperature is -20-65°C and the relative humidity is 5%-85%, the insulation resistance between the positive (A), negative (G) output and the body (shell) is ≥20MΩ.
DC-DC converter positive and negative insulation performance testing
5) Insulation performance test of the positive and negative terminals of the air conditioner compressor: disconnect the negative terminal of the low-voltage battery, unplug the high-voltage accessory harness plug of the high-voltage box, connect the black test lead of the insulation resistance meter to the vehicle body, and measure the positive pole C of the high-voltage accessory harness plug of the high-voltage box one by one with the red test pen and negative electrode H
Standard: After filling (50±1) cm3 of refrigerating machine oil and (63±1) g of HFC-134a refrigerant into the air-conditioning compressor, the insulation resistance of the positive and negative poles of the air-conditioning compressor to the body is ≥5MΩ; empty the refrigerating machine oil Finally, the insulation resistance of the body shell is ≥50MΩ.
