What Standards Must New Energy Vehicle Parts Processing Meet? 3 Compliance Points to Aviod Risks

New energy vehicle parts processing must three core compliance standards:safety compliance with GB 38031,ISO 26262 and other standards to ensure high-voltage safety and functional safety;materials and processes must meet environmental requirements and strict precision control;supply chain needs full-process traceability through Battery Passport. Compliance is key to market access.effectively avoiding penalties and order losses.

Compliance in new energy vehicle (NEV) parts processing directly determines market access and product safety. A battery accessory factory failed to enter the domestic market because it did not meet the new GB 38031—2025 national standard for thermal runaway requirements; another motor supplier missed European automaker orders for not passing the ISO 26262 functional safety certification. With tightening global standards, "safety compliance", "material environmental protection", and "supply chain traceability" have become Google's popular topics. Grasping three core points is the key to avoiding risks.​

1. Safety Standards: Build a Solid Foundation for Core Performance​

Safety is the primary requirement for NEV parts, which must meet mandatory standards in multiple countries:​

Battery-related parts must comply with GB 38031—2025 "Safety Requirements for Power Batteries for Electric Vehicles", pass bottom impact and post-fast charging cycle safety tests to achieve the goal of "no fire, no explosion";​

High-voltage components such as motors and electronic controls must meet GB 18384 "Safety Requirements for Electric Vehicles", equipped with physical button-type "one-key power-off" function and maintenance disconnect device, with insulation resistance ≥100MΩ;​

Functional safety must comply with ISO 26262 standard, and key parts (such as BMS, autonomous driving sensors) must reach ASIL-D highest safety level to reduce failure risks.​

2. Material and Process Compliance: Balance Performance and Environmental Protection​

Material selection and process control are core to compliance, requiring meeting dual requirements of "performance compliance + environmental protection restrictions":​

Prioritize materials with high conductivity and heat dissipation (such as copper alloys, aluminum alloys), avoid harmful heavy metals (lead, cadmium, etc.) with content ≤0.01%, complying with EU RoHS directive;​

Strictly control process precision: battery pole piece coating thickness tolerance ±0.01mm, motor stator winding insulation treatment must pass 1500V withstand voltage test, welding processes (such as SPR self-piercing riveting) must meet connection strength standards;​

Environmentally, comply with ISO 14001 environmental management system, ensure wastewater and waste gas emissions meet standards during production, and battery parts must meet EU battery recycling regulations (recovery rate ≥95%).​

3. Supply Chain and Traceability: Full Chain Traceable and Controllable​

Global supply chain supervision is tightening, and traceability systems have become a must for compliance:​

Implement full-process traceability, record raw material sources, production batches, and test data through Battery Passport to meet EU Battery Regulation requirements;​

The supply chain must comply with Google's Supplier Code of Conduct, ensuring raw materials (such as cobalt, lithium) procurement meets conflict mineral compliance requirements and avoiding minerals from illegal sources;​

Retain complete documentation (such as Design History File, test reports) to meet regulatory audit requirements and support product full-lifecycle traceability.
