The battery is one of the core components of new energy vehicles, and its safety performance is directly related to the driving safety of the vehicle. Battery safety testing mainly includes the following aspects:
(1) Battery capacity test: determine whether the battery meets the design requirements by measuring the capacity of the battery.
(2) Battery life test: by simulating battery recycling, test its life and usage.
(3) Battery high temperature test: test in high temperature environment to measure the performance of the battery in high temperature environment.
(4) Battery pressure test: the compression test is carried out on the battery to test its tolerance and safety.
3. Motor safety detection
The motor is one of the core components of the drive system of new energy vehicles, and its safety performance is also an important guarantee for the driving safety of new energy vehicles. Motor safety testing mainly includes the following aspects:
(1) Output power test: measure the output power of the motor to judge whether it meets the design requirements.
(2) Response speed test: test the motor response speed to evaluate the driver's experience and handling performance.
(3) Noise test: test the operating noise of the motor to evaluate the comfort and safety of the driver.
4. Charging equipment safety detection
The safety performance of new energy vehicle charging equipment is crucial to ensure the power supply throughout the driving process. The safety testing of charging equipment mainly includes the following aspects:
(1) Connection performance test: test the connection between the charging pile and the vehicle to test its connection performance.
(2) Leakage protection test: test whether the charging equipment has a leakage protection function to reduce related safety risks.
(3) Overload protection test: test whether the charging equipment has an overload protection function to prevent the occurrence of accidents such as damage to the charging equipment or fire.
Third, the development trend of new energy vehicle operation safety performance inspection technology system
The development trend of new energy vehicle operation safety performance inspection technology system mainly includes the following aspects:
Standardization: In the future, the operation safety performance inspection of new energy vehicles will be gradually standardized and standardized, forming relevant inspection standards to improve the quality and safety level of the entire industry.
Artificial intelligence: In the future, artificial intelligence technology will be gradually introduced into the operation safety performance inspection of new energy vehicles, such as the use of artificial intelligence algorithms to analyze data, identify abnormal phenomena, and increase the degree of automation and accuracy of inspection.
Multi-field crossover: New energy vehicle operation safety performance inspection requires multi-disciplinary and multi-field technical support, and the intersection of different fields will be gradually strengthened in the future, such as vehicle control, battery management, charging equipment, etc.
