“The last few years.，There are more and more pure electric mining cards used in the mining area.，Like our motorcade，Pure electric vehicles are now the absolute main force.，There are fewer and fewer oil trucks left.，And it will be gradually replaced in the next few years.。”Xing Yafeng, the fleet operation manager of a metal mine in central China, said.，Under the influence of multiple factors such as national policy and market competition，The construction of green mines has become the general trend of the whole industry.，The use of electric mining cards can not only greatly reduce carbon emissions.，And can provide bet、Longer term economic benefit。

In fact，Xing Yafeng's team began to explore the application of pure electric mining cards as early as 2016.，“At first, I just bought a few cars for trial.，After all, the road surface in the mining area is bumpy.，It is hard to say whether the motor can withstand the heavy load.，And the new energy mining card was just starting.，Technology maturity also needs to be tested.”；But after a period of trial operation,，Pure electric mining card not only“Withstood the test of potholes”，And the advantages are very obvious.：Compared with traditional fuel vehicles，Operating costs dropped by more than 90 percent，From the actual value，A pure electric mining card can save 1000 to 1500 yuan per day in energy costs.。

2021，Xing Yafeng's motorcade purchased 10 disc hubs at one time.“Double power”Pure electric mining card driven by motor，Compared with other drive motors with the same power on the market,，Disc hub“Double power”The volume and weight of the motor are reduced by about half.，And the efficient range is larger.，Stronger dynamic performance，Actual operational experience“More comfortable”。

“In fact, for the pure electric mining card，The core indicator we are most concerned about is its attendance rate.”Xing Yafeng said，Mineral cards are used as means of production，The amount of ore to be pulled each day is determined in advance.，Once a vehicle is temporarily unavailable，It is very troublesome to dispatch.，“And pure electric vehicles，The core is the motor.、Batteries and electronically controlled‘Three electricity’System，Among，The drive motor is the key to the key，If the motor is broken, the vehicle can't run at all.。”But these vehicles have been on line for three years.，Although the vehicle has been running at full capacity，“Every day, people stop and run for about 20 hours.”，But basically did not let Xing Yafeng.“Worried about what?”，In addition to routine maintenance，“It's basically full attendance.，Nothing has gone wrong.”。

The second point is the dynamic performance of the vehicle.，“Especially in a mine like the one we're in.，It's been nearly fifty years now.、The ore is basically at the bottom of the pit.，They are all working conditions of heavy load uphill.”，After the deadweight of the ore card is fully loaded with ore,，The load of the vehicle is 105 tons.，The requirement for the output power of the motor is very high.，“A very interesting thing happened in the mine some time ago.，When a fully loaded fuel truck climbs a hill,，The wheel got stuck in a small hole.，It took a lot of effort to climb out.，And an electric mining card using a disc hub motor，It was easy to climb out.”，In the course of daily operation,，“Drivers also generally feedback that these electric mining cards are much more comfortable to drive.，One is that there is no need to engage and disengage gears frequently.，In addition, there is no engine.，There is also less noise and vibration in the cab.。”

In order to facilitate the operation of the pure electric mining card,，Several charging stations have also been built in the mining area.，“The speed of charging is still OK.，Basically, you can charge 1 in a minute.%，Fully charged in more than an hour”，Plus the electric quantity supplemented by the self-recovery energy generating system of the motor，“Even under the condition of heavy load going uphill now.，It is basically enough to supplement the electricity once during the day.。”

And under the demonstration of Xing Yafeng's motorcade，Now the other two fleets in the mining area are also increasing the proportion of pure electric mining cards.，“All things considered，Motor quality and stability of disk hub、Reliability performance is still very good.”Xing Yafeng said，With the experience of this batch of cars.，Disc hubs will still be preferred for subsequent vehicle replacement“Double power”Lectric mining card for motor，“It fully upgrades the performance of the electric mining card.，It's like the mining card world.‘New Quality Productivity’，More in line with our operational needs”。
