Field tests at Yantian Port in Shenzhen indicate that electric heavy trucks can reduce carbon dioxide emissions by 2.3 tons per day. This number means that the annual reduction from every 20 electric heavy trucks is equivalent to planting 1,500 mature trees. BYD's electric dump truck project has also enhanced energy utilization by 18% through an intelligent energy consumption management system.
It is noteworthy that the choice of charging periods directly impacts the effectiveness of emissions reductions. Vehicles charged during night off-peak hours can reduce their full lifecycle carbon footprint by 27% compared to daytime charging. This green charging model is being promoted in the Yangtze River Delta logistics hubs, in conjunction with the use of photovoltaic carports, creating a virtuous cycle.
Data from the Beijing Environmental Protection Bureau shows that in the area within the Fifth Ring Road, the average daily concentration of PM2.5 decreased by 9.6 micrograms per cubic meter after the electrification of logistics vehicles. This is equivalent to reducing exhaust emissions from 2 million private cars. JD Logistics' Qingliu plan, by deploying 500 electric delivery vehicles, has reduced nitrogen oxide concentrations around its warehousing areas by 43%.
During a pilot of night-time electric truck deliveries in Shenzhen, SF Express discovered that vehicle operating noise decreased from 78 decibels to 61 decibels. This change led to an 82% reduction in resident complaints, while delivery efficiency improved by 15%. Vehicles with variable frequency electric drive systems can keep noise levels below 55 decibels during low-speed operation, fully meeting nighttime noise standards for residential areas.
The electric ground handling equipment renovation project at Shenzhen Bao'an International Airport reduced nighttime noise levels around the terminal from 72 dB(A) to 64 dB(A), significantly improving the working environment for crew members.
In the lithium muscovite purification project in Yichun, Jiangxi, the recovery rate of lithium resources increased from 60% to 85% through the application of membrane separation technology. The new solid electrolyte material developed by Ganfeng Lithium has improved the cycle life of battery packs to over 4,000 times, an increase of 30% compared to traditional products.
According to calculations by Deppon Logistics, although the purchase cost of electric heavy trucks is 400,000 yuan higher, they can save 680,000 yuan in fuel costs over a five-year operating cycle. This payback period has been reduced to 3.2 years, and with the popularization of battery leasing models, the pressure of initial investments continues to decrease.

Annual maintenance costs | 45,000 yuan | 21,000 yuan |
The mileage billing plan launched by Ground Iron car rental packages battery loss and electricity expenses into one price. After a certain delivery company adopted this model, their per-parcel transport cost decreased by 0.15 yuan, saving over 2 million yuan annually. This pay-as-you-go model is reshaping the industry cost structure.
The megawatt-level battery swapping station built in Suzhou can complete the battery replacement of a 49-ton heavy truck in just 5 minutes. This speed is 12 times faster than traditional charging, enabling electric heavy truck operational efficiency to surpass that of diesel trucks for the first time. With the assistance of an intelligent scheduling system, vehicle utilization increased to 92%.
TuSimple's autonomous electric container trucks tested at Caofeidian Port use V2X technology to achieve platooning. Test data shows that this mode can reduce aerodynamic drag by 15% and improve overall energy efficiency by 8%. When maintaining a distance of 10 meters between vehicles, energy consumption can drop by another 3%.
