Pre-charging Load and Fault Emulator
Pre-charging process is critical for vehicle power step, the voltage edge dominated by Pre-charging load has to be verified with repetitive cycles and even with possible interference by ON/OFF operation.
The HV-specific LV Signals and LV Signal chains has to be tested as part of electrical test regarding the functionality and reliability.
Both the robustness and essential fault event has to be tested in emulation of a real vehicle. Stropower’s Pre-charging Load and Fault Emulator is designed to perform required pre-charging load and fault emulation according to VW80300-2021 standard.
Features of Stropower Pre-charging Load and Fault Emulator
