Proposed Increase in Type Approval Test Mileage for New Energy Vehicles to 30,000 Kilometers

[Policy Adjustment] The national standard proposes abolishing the '50% reduction rule' that has been in place for 21 years, aligning the type approval test mileage for new energy vehicles with that of internal combustion engine vehicles.

Core Development: Full Alignment of Reliability Testing Thresholds

The National Technical Committee on Automotive Standardization is soliciting public comments on amendments to three national standards, including GB/T 18388—2005, proposing to uniformly raise the total mileage requirement for reliability driving tests for battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and fuel cell vehicles (FCVs) to no less than 30,000 kilometers. The comment period ends on August 12, 2026.

Key Data: Clear Specifications for Fast Charging Proportion and Driving Modes

For BEVs, at least 90% of the 30,000 kilometers (i.e., no less than 27,000 kilometers) must be completed using DC fast charging; PHEVs must additionally complete at least 10,000 kilometers in pure electric mode; FCVs must accumulate the full 30,000 kilometers under hybrid operation mode.

Strategic Rationale: Transition from 'Simplified Validation' to 'Real-World Scenarios'

The '50% reduction rule,' established in 2005, reflected the industry reality at the time when annual production and sales totaled fewer than 10,000 units. Today, with new energy vehicle market penetration exceeding 60%, this standard upgrade aims to mitigate risks associated with hastily developed vehicles and reinforce fundamental safety requirements.
