    • Automotive High-Voltage Electrical Performance Test System

    The automotive high-voltage electrical performance testing system is suitable for testing high-voltage components of new energy vehicles within the voltage range of DC 60V ~ 1500V. A series of electrical characteristic tests can be used to verify the electrical parameters and safety of high-voltage components such as HV battery system, DC/DC Converter HV/LV, on-board charger, and air conditioning compressor.
    The automotive high-voltage electrical performance test system EVP-1530 supports DC 0V ~ 1500V voltage output with a voltage slope up to 500V/ms. It can complete the test items of ISO 21498-2-2021, and can also meet the relevant test requirements of LV123 and VW80300_2021. The system has strong scalability. Products with higher voltage and current can be customized according to requirements.
    According to standards: ISO 21498-2-2021, LV123, VW80300_2021, etc.
