The speed of charging electric mining trucks is faster than that of household cars? Don’t doubt it! Everything is possible. Now, with the popularization of new energy equipment in the construction of green mines, “super fast charging” has become an important means to solve the anxiety of electric mining vehicle mileage. From a macro perspective, the construction of more super charging stations in China’s mines is an irreversible trend, after all, it can maximize the work efficiency of electric mining trucks, and mine owners naturally have no reason not to take it seriously.
A set of data may better illustrate the issue. According to the relevant agency’s prediction, by 2030, more than 50% of China’s green mines will have supercharging stations. The trend is unstoppable, and excellent companies that dare to break through themselves will naturally bring forth new ideas, such as Weihong Power. China Truck Network has learned that the combination of Weihong’s fast-charging batteries and super fast-charging technology is leading the high-quality operation of green mine pure electric wide-body vehicles.
As a wholly-owned subsidiary of MicroMacro Power, Huzhou Hongwei New Energy Automobile Co., Ltd. relies on MicroMacro Power’s advantages in power battery and charging technology to provide an efficient, profitable, high-quality, and safe integrated solution for the electrification of the construction machinery industry with the “New Generation Engineering Machinery Supercharging Architecture”. In November 2022, 8 new energy mining trucks equipped with MicroMacro fast-charging battery systems were put into operation in a mine area on the plateau of Inner Mongolia. These supercharged pure electric mining trucks are mainly used for short-distance transportation of waste earth, ash, and scrap in the mine area, with a one-way distance of about 5 kilometers. After more than a year of commercial operation verification, the high efficiency, energy saving, and 24-hour full-time operation of the super fast-charging new energy wide-body truck have been fully demonstrated.
So, how much efficiency improvement can the use of the Hongwei super-fast charging architecture for pure electric mining vehicles bring? In this regard, the mine fleet manager, Deng Yandong, expressed his views. According to Manager Deng, Hongwei’s super-fast charging pile has an output power of 1320kw, far exceeding the 320kw charging piles used in other mines on the market. Due to the fast-charging batteries carried by the vehicles and the matching super-fast charging technology, each charging process is super fast, basically completing in about 20 minutes. Although the mining truck carries a large battery of over 500 kWh, the “charging efficiency is faster than our own small electric cars”; charging and replenishing the battery 4 times a day, with a total charging time of about 80 minutes, “less than 1.5 hours, many vehicle models take more than this time for one charge.” In fact, with the drive of the national “peak carbon, carbon neutrality” strategic goals, and the popularization of green new energy equipment in the “14th Five-Year Plan” for construction machinery, under the support of Weihao’s “10-minute fast-charging battery technology”, Weihao New Energy has launched the “new generation of construction machinery super-charging architecture”: megawatt-level super charging piles + super-fast charging batteries + ultra-efficient power system “golden partner combination”. The product is suitable for various climate conditions, and mine types include sand and gravel, non-ferrous metals, coal, etc., achieving a performance of over 700 units/sets, and establishing stable cooperation relationships with several central and state-owned enterprises. The product has even reached as far as Vale in Brazil, demonstrating the confidence and strength of Chinese manufacturing.
Undoubtedly, the era of super fast charging in the commercial field has arrived. The efficient, profitable, high-quality, and safe charging solution brought by MicroMacro fast charging battery + super charging technology will also become the choice of more and more green mines.
