The "Eleventh Five-Year" National 863 Program "Energy-saving and New Energy Vehicle" project "Research on Vehicle Performance and Emission Test Technology for Hybrid and Fuel Cell Electric Vehicles" passed the project acceptance in Tianjin.

In the test technology of heavy-duty hybrid electric vehicles, a laboratory test system for heavy-duty hybrid vehicles based on test methods for chassis dynamometers and a road test for key performance of heavy-duty hybrid electric vehicles based on vehicle emission test technology were built. The system solves the problem that the heavy vehicle emission regulations system based on the current engine test cannot cover the hybrid vehicle. In the test technology of light hybrid electric vehicles, an emission energy consumption laboratory that satisfies the technical requirements for emission regulations in the new phase has been established, and test procedures for the evaluation of the overall vehicle performance such as the energy consumption of plug-in hybrid vehicles have been developed and validated. Solved the focus of the test and evaluation of plug-in hybrid vehicles.

In the fuel cell vehicle energy consumption test technology, a hydrogen consumption measurement system based on a mass weighing method and a temperature pressure method and a flow meter method detection capability was established to solve the fuel economy of fuel cell vehicles. Accurate evaluation of technical problems.

In terms of durable reliability testing technology for fuel cell vehicles, a rapid reliability evaluation method for critical components of fuel cell vehicles based on enhanced road vibration spectrum iterations and durability evaluation of component vibration tables was developed and solved for fuel cell vehicles. The technical problems of rapid assessment of key components for reliability; fuel cell vehicle hydrogen leakage emission testing, research and development of a closed chamber test system, to solve the technical problems of fuel cell vehicle hydrogen leakage and quantitative testing of emissions.
