How To Test 800V High-Voltage Fast Charging Platform with Test Power Supply?

Industry background

Against the backdrop of new energy vehicle range and charging experience becoming the core pain points, in order to solve the current bottleneck (heat generation, loss, weight cost) faced by high-power fast charging on the 400V platform, while pursuing higher system efficiency and performance potential, relying on the progress of battery technology, the maturity of SiC power devices, and the promotion of policy regulations and market demand for ultra fast charging, supported by the rapid development of the entire industry chain, the 800V high-voltage platform has emerged and quickly become the mainstream technology direction for the development of mid to high end electric vehicles. Under this trend, how to test high-voltage platforms faces new challenges!

Test Pain Points

Higher voltage level: Testing equipment (such as power supplies and loads) must support higher voltages (>1000V or even higher), and insulation level requirements must be increased.

More stringent dynamic response: During the fast charging process, the current and voltage changes dramatically, and the test power supply needs to have extremely fast transient response capability and high accuracy.

The complexity of system integration testing has increased: the collaborative work and safety protection logic testing of battery packs, motors, electronic controls, OBC, and DC/DC on high-voltage platforms are more complex, requiring multi-channel, programmable test power supplies to simulate various working conditions.
