Efficient Equipment Inspection Case: Specialized Inspection Tooling for New Energy Vehicle Safety Compliance Testing

In the manufacturing of new energy vehicles, production lines often require multiple safety inspection devices. These devices must obtain annual metrological qualification certificates from third-party certification bodies to remain operational. Given China's rapid annual growth in new energy vehicle production and sales, most manufacturers maintain full production capacity for extended periods. The annual certification cycle from third-party institutions proves insufficient to ensure equipment remains in optimal working condition throughout their validity periods. Additionally, inspection stations typically feature high-frequency operations, frequent equipment activation, and lengthy test cables. The high production volume necessitates regular cable replacement, which may introduce issues like cable breaks or poor connections before and after replacement. Such problems can lead to measurement accuracy deviations in inspection equipment, potentially resulting in undetected vehicles.

Addressing the aforementioned on-site pain points and meeting customers' practical needs, Yidi Electronics has officially launched a comprehensive safety inspection system for new energy vehicle testing equipment this year. The product has quickly gained popularity among automakers, being implemented in multiple production bases of Geely Auto, BAIC, and other manufacturers. It enables daily or weekly inspections of all testing equipment on production lines, effectively preventing issues like equipment accuracy deviations or vehicle omissions. The inspection system achieves multi-functional integration, allowing a single unit to inspect all factory equipment while verifying compliance with four international standards: China, Europe, America, and Japan. Its mobile design allows flexible deployment across various production lines.

• From January to September 2025, China produced 11.243 million new‑energy vehicles, up 35.2% year‑on‑year. Exports reached 1.758 million units, a sharp 89.4% year‑on‑year rise, making NEVs a core growth engine for China’s auto exports. Domestic manufacturers ran production lines at near‑full capacity; safety‑inspection equipment at several plants recorded utilization rates above 90%, reflecting heavy equipment operation.

• China’s new‑energy vehicle manufacturing mainly follows GB 18384, which defines strict electrical‑safety rules. Vehicles shall complete full‑scope factory tests covering potential balancing, insulation resistance, whole‑vehicle insulation and insulation‑monitoring function verification. Units that fail inspection are barred from market launch.


• Yidi Electronics’ dedicated inspection toolset performs multi‑parameter measurements including potential balancing, insulation resistance, whole‑vehicle insulation and leakage current. It also works with Yidi’s proprietary battery‑pack test equipment for pre‑delivery inspections of battery‑pack equipped vehicles.

① The comprehensive inspection system supports the following checks: component insulation resistance, charging port insulation resistance, component potential balance, charging port potential balance, vehicle-wide insulation resistance, charging port leakage current, and battery terminal voltage. It also verifies the connectivity status of all wiring harnesses and confirms whether the equipment's detection accuracy meets specified tolerance limits.

② Multi-point inspection Each inspection item is equipped with multiple measurement points to cover the full range of safety equipment, ensuring the equipment remains in good condition throughout its entire test range.

③ Quick verification connects all detection line bundles of the equipment to the inspection fixture. By setting up a dedicated inspection test program in the upper computer software of the equipment, all items can be tested in one time. In addition, the inspection data can be stored for a long time to form a traceability mechanism.

Yidi's specialized inspection tool efficiently performs physical examinations on safety inspection equipment for new energy vehicles, ensuring detection accuracy and stability. This guarantees comprehensive verification of every vehicle, thereby safeguarding the efficient production of automakers.
