  • New energy automobiles are developing rapidly, and testing is key to guarantee quality. ITECH has rich experience and advanced products in tests of vehicle power batteries and charge/piles/vehicle-mounted chargers. For the vehicle power supply system with complex output, the power voltage output always fluctuates as a result of high-current motors, electromagnetic valves, etc., and high-voltage pulsation or drop occurs frequently, resulting in challenges to stable operation of on-board electronic products. ITECH offers solutions meeting ISO16750-2 and DIN40839 standards and provides mature, reliable and comprehensive automobile electronic test solutions.

  • Automobile electronic and electrical test:
    In addition to the complex external environment, the internal electromagnetic environment is also harsh in a car during traveling. The performance and reliability of automobile electronic and electrical products depend on the anti-interference ability to a larger extent. In the electromagnetic physical environment in a car, unstable power voltage and transient over-voltage has serious impact on working electronic devices. Automobile electronic and electrical products generally include electric window, wiper, vehicle-mounted audio equipment, etc., which should be subject to detailed tests to guarantee the overall performance. DIN40839 and ISO-16750-2 are the most commonly used in automobile electronic tests at present. ITECH provides automobile electronic and electrical test solutions based on these two standards. The standard voltage sequence of the voltage curve for the automobile electronic power network, which complies with the two standards, is set in the DC power supply, so that the engineer can rapidly call it in tests. Meanwhile, the solutions of ITECH are programmable, and the waveform can be edited by the user as required.

    *  The vehicle-mounted charger/charge pile test system of ITECH is developed based on the ITS9500 power supply test system
     
    Instrument test solution
    The vehicle-mounted charger and charge pile are high-power products. The programmable DC electronic load capable of simulating the power battery is required in the test. ITECH products has the unit power of 600KW, multiple working modes such as CC/CV/CR/CW/CZ and the function of battery simulation, fully meeting the test requirements of high-power charge piles. The no-load test can be tested when the charge pile is charged, or the gradual voltage rise can be simulated to check whether the current is normal, etc.

    Test solution for central control box:
    The central control box test system of ITECH is built with the ITECH programmable electronic load, programmable power supply and other test equipment as well as test software. It can be used for testing the long-time stability of the central control box, the relay life, the fuse and other important performance indicators such as the temperature and fault alarm. The graphic editing interface can be provided and easily operated. The relay ON/OFF time sequence, load current, operating time sequence and channel name can be edited. In the case of failure of one channel, alarm will be sent automatically by software and the channel will stop working, with no influence on normal operation of other channels. The software operating interface can show the voltage, current, temperature, operating time, operating state, I/O state, etc.
