New Energy Heavy Truck Development In recent years, new energy heavy truck development, in the field of heavy trucks with higher requirements for new energy power systems, hybrid, pure electric and fuel cell technologies have continued to develop, new application scenarios have been continuously developed, and demand has continued to grow. New energy heavy trucks have already shown development potential. 1 Technical status of hybrid heavy trucks So far, the development of new energy vehicle technology, hybrid technology is the most mature, and the increased cost is the smallest. At present, the hybrid power system includes three types: series, parallel and hybrid. The parallel hybrid power system is composed of a traditional internal combustion engine system and a motor drive system. The engine, motor, and transmission are combined to form different power modes, which can be applied to a variety of different driving conditions and have high energy utilization. At pres...
