Under GTR 25, a feasibility assessment proposes introducing a 5-year mid-term performance requirement threshold together with corresponding mileage and energy-throughput limits as an intermediate verification checkpoint for battery degradation. Based on analysis of State-of-Health data from vehicles with 5-year life and mileage ranging from 250,000 km to 350,000 km, the MPR value is set at 75%, which can cover 98% battery-durability performance. Specific mileage and energy-throughput limits are established for vehicle categories M₂, M₃, N₂, and N₃.
