China’s Ministry of Industry and Information Technology (MIIT) released Monday a clarification on the new technical standards it proposed for refining EV qualification for vehicle purchase tax reduction, Kallanish learns.
The transition period for the new standards will be from 1 January to 31 May 2024. From 1 June next year, models not included in the new list will not be considered for tax cuts.
Compared to the current standards, the battery electric passenger car mileage range requirement was increased from 100 kilometres and above to 200 km and above. The mass energy density requirement for battery electric passenger car power battery system was increased from 95 watt-hours/kilogram to 125 Wh/kg and above.
The new standards also set higher requirements on system rated power, and its ratio with the motor for BEVs and hydrogen fuel cell vehicles. It also adds new requirements on fuel cell battery starting temperature, fuel cell stack rated density, and system rated power density.
Additionally, the new standards include new indicators for low-temperature mileage attenuation. For battery electric passenger cars and Type N1 battery electric trucks (under the appendix A of light-weighted car section under the GB/T 18386.1 classification), if the low-temperature mileage attenuation rate is below 35%, the energy density of the battery system can be relaxed to 95 watt-hours/kilogram, and the mileage range requirement of battery electric passenger vehicles can be relaxed to 120 km.
It also specifies that the battery swapping models should follow the standards of GB/T 40032 to ensure actual use of the technology.
The MIIT explained that to accommodate the development of the industry, guide the related enterprises to further improve product quality and functions, and promote high-quality development, it is urgently necessary to change and optimise the technical requirements for tax benefits consideration.
It said the decision was made after conducting in-depth research, seeking advice from various perspectives, and launching professional discussions.
Carmakers now need to apply to have the models verified before the government can decide which models are eligible for the tax reduction.
