Beijing Heavy-Duty Diesel Vehicle Battery Capacity Conversion and Emission Estimation in 2022

Road transport is a scenario for the use of fossil fuels to a large extent, and the process of electrification can slow down this use of fossil fuels. This study analyzes the annual emissions of nitrogen oxides (NOX) and carbon dioxide (CO2) from heavy-duty diesel vehicles (HDDVs) and the feasibility of electrification in Beijing based on the on-board diagnostics (OBD) of remote monitoring data from more than 9000 HDDVs. The annual NOX and CO2 emissions of 13 industry types were 44,980.9 and 6,658,722.6 tons in 2022. The highest contributor to these NOX and CO2 emissions was concrete trucks, accounting for 27.1% and 17.0% of the 13 industry type vehicles. The electrification of concrete trucks can greatly reduce the diesel emissions in Pinggu and other districts and realize regional emission reduction management. The CO2 emission factor of passenger buses in the Pinggu district was significantly higher than that in other districts, which was 1212.4 g/km, and the electrification of passenger buses could significantly reduce the CO2 emissions in the Pinggu district. This study investigates HDDVs in Beijing, provides a scientific basis for the electrification management of key models in Beijing, and provides a regional reference for the electrification trend of HDDVs in various countries worldwide.
