Intelligent and Integrated Driving - New Trends in Testing of Electric Control Systems for New Energy Vehicles

Industry background

At present, China's new energy vehicle industry has entered a stage of sustained growth and large-scale development. According to authoritative statistical data, the new energy vehicle market in China will continue its steady growth trend in 2024, with annual sales of 12.87 million vehicles, a year-on-year increase of 36%, and a market penetration rate of 41%. The testing demand for high-power drive motors and supporting equipment such as electronic control systems, which are core components, has shown a significant growth trend.

Test pain points

·High precision and fast response: The test power supply meets the requirements of precise power supply and dynamic simulation.

·Powerful programmability and sequential functionality: It is necessary to simulate complex power supply timing and fault scenarios.

·Complete protection and isolation: protect the tested equipment and the testing equipment itself.

·Good communication interface: seamlessly integrated into automated testing systems (CAN, LAN, USB, GPIB, etc.).

Solution

To address the testing pain points mentioned above, Aino has launched the wide range programmable DC power supply AN53 series, which adopts active power factor correction technology and high-frequency LLC multi resonant soft switching inverter technology. This series has high power factor, fast dynamic response, low output ripple, and high power density. It has the characteristic performance of constant power wide range output, as well as the advantages of small size, light weight, low noise, high efficiency, and simple operation.
