Leveraging the resources of the energy and power engineering discipline and aligning with the electrification trend in vehicles, his research focuses on the supply reliability, source quantification, and usage safety of carbon-free vehicle energy. This encompasses studies on battery eruption and combustion, grid-electricity-to-fuel-energy decoupling, and hydrogen energy flow mapping. He developed a constant-volume adiabatic pressure combustion test chamber for lithium-ion batteries and created thermal runaway disaster suppression technology for power batteries in pure electric vehicles. Based on hydrogen production and utilization, he mapped China’s hydrogen energy flow and proposed a technology roadmap for hydrogen fuel cell vehicles in China. He also invented a grid-electricity-to-fuel-energy decoupling algorithm for plug-in hybrid electric vehicles, optimizing the scientific methodology for assessing their energy savings and emission reduction.
In the area of low-carbon quantification of vehicle energy, he developed a big data analysis platform for new energy vehicle travel and charging. His work revealed the gamma distribution pattern of travel mileage for new energy vehicles in China, and he invented an oil-electricity energy decoupling algorithm for new energy vehicles. This provided a scientific method for quantifying the energy consumption and emissions of new energy vehicles, filling a domestic gap in this field.
Regarding the passive safety of vehicle power batteries, he developed China’s first set of large-capacity lithium battery combustion safety performance testing equipment. This system enables synchronous detection of comprehensive "thermal-electrical" parameters during battery thermal runaway and in-situ detection of characteristic components, allowing for scientifically quantified analysis of battery safety.
He achieved innovative practical exploration in the technology roadmap for hydrogen fuel cell vehicles. He led the implementation of a full-chain hydrogen industry development layout in Zhangjiakou City, exploring a zero-carbon hydrogen pathway, which was recognized and commended by the State Council (2020). He also developed a full-process safety monitoring system covering hydrogen "production-storage-transportation-refueling-application" in Zhangjiakou, supporting the operation of over 1,000 fuel cell vehicles during the 2022 Beijing Winter Olympics.
