II. Why do electric drives in new energy vehicles need to undergo safety regulations testing?

The core purpose of safety testing for electric drives in new energy vehicles is to avoid safety risks posed by high-voltage systems, ensure the safety of personnel and vehicles, and meet industry compliance and product reliability requirements.

III. What are the safety risks associated with the electric drive system of new energy vehicles?

As a high-voltage core component of new energy vehicles, the electric drive system must meet three core safety risks: "prevention of electric shock, prevention of insulation failure, and prevention of electrical fires".

IV. In response to the above safety risks, what are the core test items of the electric drive safety testing system for new energy vehicles?

1. Insulation resistance test: mainly used to test the insulation performance between live parts and the housing in automotive electric drive systems, to avoid the risk of leakage due to insulation aging.

2. Hi-pot test (AC/DC): Simulates an extreme voltage environment to verify whether the insulation layer can withstand instantaneous high voltage and prevent breakdown and short circuit.

3. Grounding resistance test: Confirms the continuity of the grounding circuit of the vehicle's electric drive housing to ensure that leakage current can be quickly conducted to the ground to protect personnel safety.

4. Potential Equalization Test: A unique safety test item for new energy vehicles, used to ensure that the exposed conductive parts of the equipment are reliably connected to the "electric platform" and meet the equipotential design standards, eliminating the risk of electric shock due to potential difference.

V. When selecting a safety testing system for electric drive systems of new energy vehicles, in addition to meeting the standard requirements, what key technical indicators should be paid attention to?

1. Test item accuracy: The test error for AC/DC voltage, insulation resistance, and grounding resistance is ±(0.1%*set value/reading + 2V), and the test accuracy for potential equalization is ±(0.5%*displayed value + 2 digits), to avoid misjudgment due to insufficient accuracy.

2. Data traceability capability: The safety testing system has network connectivity for test data management, analysis, and uploading. It interfaces with the MES information system and can export or upload data.

3. Safety protection level: High voltage safety protection requires a dual safety mechanism. The "high voltage circuit contact detection" function can automatically disconnect the output when personnel accidentally touch the high voltage test line to ensure personnel safety.

VI. Precautions for Daily Use of New Energy Vehicle Electric Drive Safety Tester

1. During the test, it is strictly forbidden to touch the test object or the outer casing of the instrument or equipment to prevent electric shock!

2. If any abnormality is found, immediately disconnect the power switch of the electric drive safety test system or press the emergency stop button to disconnect the equipment output.

3. The testing system must be safely grounded. Operators must not wear clothing with metal decorations or metal jewelry or watches, and must wear safety insulating gloves and safety insulating shoes.

4. The automotive electric drive safety testing system shall be calibrated at least once a year.
