With the transformation of automobiles and the intensification of the energy crisis, new energy vehicles have become an important research and development direction in global parking yards. As a core component of new energy vehicles, power batteries have become the key to the vigorous development of new energy vehicles. We understand the way to quality and help you improve product safety and quality and open up markets.

1. Power battery testing:

• Electrical performance test:Including capacity, energy, power, internal resistance, etc. tests to evaluate the performance of the battery.
• Safety and reliability testing:Covering tests such as no-load capacity loss, storage capacity loss, and energy efficiency to verify the safety and stability of the battery under various circumstances.
• Temperature environment adaptability test:Including temperature shock, moist heat cycling, seawater immersion and other tests to test the adaptability of the battery under different environmental conditions.
• Electromagnetic compatibility test:Conduct radiated emission and immunity tests to ensure that the battery does not interfere with the normal operation of other electronic equipment.

2. Motor electronic control testing:

• Electrical performance test:Including working voltage range, torque-speed characteristics, sustained torque, sustained power and other tests to verify the performance of the motor.
• Safety testing:Covering safe grounding and temperature rise limit testing to ensure the safety of the motor during normal operation.
• Environmental adaptability testing:Including high and low temperature operation/storage, damp heat, dust and water resistance tests to verify the reliability of the motor in various environments.

3. Charging interface and charging pile test:

• Functional check:Test the basic functions of the charging pile, including connection, communication and charging start and stop.
• Insulation performance test:Verify the insulation performance of charging equipment to ensure the safety of the charging process.
• Charging output test:Test the output voltage and current of the charging pile to verify its charging performance.
• Safety requirements testing:Covering over-voltage, over-current, over-temperature and other tests to ensure the safety of the charging process.
• Compatibility testing:Verify the compatibility of the charging pile with the vehicle to ensure that the charging equipment can work normally.

4. High-voltage wiring harness test:

• Electrical performance test:Include contact resistance and voltage drop tests to verify the conductive properties of the wiring harness.
• Mechanical performance test:Covering vibration, mechanical impact, insertion/extraction force testing, etc., to test the stability of the wiring harness under various mechanical conditions.
• Environmental adaptability testing:Including high and low temperature, damp heat, salt spray and other tests to ensure the durability of the wiring harness in different environments.
