On February 19, 2022, the signing ceremony of 1,000 pure electric heavy trucks between SAIC Hongyan, Jiafeng Stone, and SPIC "Ecological Macheng, Green Mine" was held in Macheng, Hubei. The signing of this contract is an opportunity for the transformation of the green transportation system, and the three parties jointly help to create a "mine ecosystem" in Macheng.

Macheng, Hubei, known as the "Hometown of Granite in China", is rich in mineral resources, and the stone industry is an important local pillar industry. Under the background of the "double carbon" goal, Macheng actively promotes the green transformation and upgrading of the stone industry, and is committed to building a national demonstration city for high-quality development of the stone industry, and building it into an important first-level stone processing trade distribution center in the central region of China's stone industry.

As one of the earliest companies to enter the field of new energy heavy trucks in China, SAIC Hongyan relies on the strong empowerment of SAIC Group, and its new energy products have been put into commercial operation in Hebei, Shanxi, Henan, Guizhou, Ordos and other places, covering steel mills, Power plants, coal mines, ports and other usage scenarios have achieved good social, economic and environmental benefits.

Based on the excellent product strength and market reputation, the 1,000 SAIC Hongyan pure electric heavy trucks signed this time will play an important role in the construction of "green mines" in Macheng. Through the previous mine field research, SAIC Hongyan will custom develop a short-wheelbase pure electric 6×4 dump truck, which is mainly used for round-trip transportation from the mine to the stockyard. In addition, the pure electric 8×4 dump truck will be used in the stone industrial park. Short-term transportation to meet the needs of users for green, environmentally friendly, economical and efficient vehicles.

In terms of environmental benefits, SAIC Hongyan’s pure electric heavy-duty truck does not require fossil fuel drive, effectively eliminating carbon oxides and other exhaust emissions. In addition, the motor has low noise, and the cab interior is made of environmentally friendly and harmless materials, which truly realizes emission, noise, and driving. The cabin is "zero pollution", so that the whole process of stone transportation is green and clean. It is estimated that 100 vehicles can effectively reduce the coal consumption by 1920t, and reduce the emission of 1632t carbon dust, 5982t carbon dioxide, 180t sulfur dioxide and other harmful substances.

In terms of economic benefits, SAIC Hongyan fully electric heavy-duty truck is equipped with a 282kW·h Ningde era power battery, and is equipped with a national power investment and replacement system. The rated power of the motor is 250kW, and the peak power can reach 360kW. The kinetic energy conversion efficiency of the motor is expected to be over 95%, 490 horsepower, with a range of about 200 kilometers. Especially in mine transportation scenarios, a large number of heavy-load downhill sections are usually encountered. At this time, the vehicle can be reversely charged to achieve energy recovery.

At the same time, SAIC Hongyan fully electric heavy-duty truck adopts a battery-electricity-separated battery-changing mode. Users can lease batteries, which not only greatly reduces the cost of purchasing a car, but also takes only 3-5 minutes to complete the battery replacement, which greatly relieves the anxiety of waiting for charging. , so as to effectively ensure the efficient operation of mines and parks.

The signing of the 1,000-vehicle contract is not only an important start for SAIC Hongyan in helping the construction of "green mines" in Macheng, but also a major breakthrough in the application of SAIC Hongyan's new energy heavy trucks in mining scenarios.Editor/Ma Xue
