Outline
At present, the development of electrification of heavy-duty trucks has ushered in an important development opportunity. Building a green energy freight transport system based on electricity has become a consensus for the low-carbon transformation and development of freight transport in the transportation industry. Among them, the selection of typical freight scenarios and the matching of the performance of new energy trucks are crucial. Based on the overall cost analysis method, this article studies the economy of heavy-duty trucks under different technical routes such as traditional fuel, rechargeable pure electric, and exchangeable pure electric (self-owned or leased) in typical application scenarios in the Nangang Port area of Tianjin. This study finds that pure electric heavy-duty trucks in the Nangang Port area application scenario have cost advantages over traditional fuel heavy-duty trucks, with the exchangeable pure electric heavy-duty trucks having lower TCO costs.
