Background

With the rapid advancement of vehicle electrification and intelligence, the 48V electrical system has become the mainstream core architecture for hybrid vehicles and high‑power onboard equipment. The electrical performance, supply stability, and operating‑condition adaptability of onboard components and electrical systems directly determine the reliability and safety of the entire vehicle. Accurately reproducing the resistance‑capacitance (R‑C) characteristics of the vehicle’s electrical network and simulating real‑world driving grid conditions have become fundamental to the R&D and type approval testing of automotive 48V systems and their components.

Technical Challenges

ISO 21780:2020 and GB/T 45120:2024 standards, specifically Test 04 and Test 07, impose stringent requirements on the R‑C parameter accuracy and operating‑condition reproduction capability for 48V vehicle network simulation. The industry currently faces common pain points: large variations in wiring harness impedance and parasitic capacitance across different vehicle models, difficulty in flexibly switching R‑C parameters, precise control of parameters under high‑current conditions, and the challenge of balancing test efficiency with safety protection. A specialized vehicle network simulation device that meets standard requirements and adapts to various electrical performance testing scenarios is urgently needed.
