In the R&D and mass production of new energy vehicles, the performance testing of various electrical components is the key to ensuring the quality of the whole vehicle. As the core power supply equipment in the testing link, the DC regulated power supply's output characteristics and adaptability directly determine the accuracy of test data. Components such as batteries, motor controllers and DC/DC converters of new energy vehicles have strict requirements on the stability and precision of power supply. Selecting a suitable DC regulated power supply can make the test process more in line with the actual working conditions of the whole vehicle, and the selection of DC regulated power supply has also become an important consideration in the field of new energy vehicle testing.
Performance Requirements for Adapting to Test Needs
The selection of DC regulated power supply first follows the principle of matching the test items, and the parameter requirements of DC regulated power supply for different component tests are different. For battery pack charge and discharge testing, the DC regulated power supply needs to have a wide voltage adjustment range, and the current accuracy should be controlled within ±0.2%, which can simulate the voltage fluctuation state of power batteries; motor controller testing requires the DC regulated power supply to have a fast dynamic response speed, which can cope with the step change of load, and the output ripple should be controlled at a low level to avoid ripple interfering with test results. In addition, the DC regulated power supply must be equipped with a complete overvoltage, overcurrent and overtemperature protection mechanism, which can cut off the power supply in time when the test components are abnormal, protect the test equipment and the tested components, and this is the necessary performance foundation for the DC regulated power supply in new energy vehicle testing.
Consideration of Functional Characteristics in Line with Vehicle Working Conditions
The actual driving conditions of new energy vehicles are complex and changeable, and the DC regulated power supply in the test link needs to simulate various complex working conditions, which puts forward higher requirements for the functional design of the DC regulated power supply. High-quality DC regulated power supply needs to support programmable operation, can preset the change curves of voltage and current, and simulate the power supply state under different working conditions such as vehicle start and stop, acceleration and deceleration; for the high and low temperature testing of DC/DC converters, the DC regulated power supply needs to maintain stable output in different temperature and humidity environments without being affected by environmental factors. At the same time, the line voltage drop compensation function of the DC regulated power supply is also particularly important, which can automatically compensate the voltage loss of the load connection line and make the power supply parameters more in line with the actual situation. The DC regulated power supply of YIBENYUAN has made targeted designs on these functional characteristics, adapting to the multi-scenario test needs of new energy vehicles.
Practicality and Adaptability in Test Operation
The selection of DC regulated power supply also needs to take into account the use needs in test operation and improve test efficiency. The operation interface of the DC regulated power supply should be simple and easy to understand, supporting both local and remote control, and adapting to the needs of laboratory automated testing; the volume and installation method should be flexible, which can be placed according to the layout of the test site, and has good heat dissipation performance to meet the requirements of long-term continuous testing. In addition, the DC regulated power supply must have the characteristics of low harmonic interference, avoid signal interference to the precision testing instruments in the test, and ensure the authenticity of the test data, which is also an indispensable selection point for the DC regulated power supply in the comprehensive testing of new energy vehicles.
There is no uniform standard answer for the selection of DC regulated power supply in new energy vehicle testing, and the core lies in the high adaptability to the test components and test working conditions. Considering the adaptability of the DC regulated power supply from multiple dimensions, from performance parameters and functional characteristics to operational practicality, the DC regulated power supply can exert the maximum value in the test, provide accurate and stable power supply support for the performance verification of various components of new energy vehicles, and help the efficient development of the new energy vehicle testing link.
