【China Road Machinery Network Original report】With“Double Carbon”Strategy implementation，The country's requirements for environmental protection are getting higher and higher.，Clean energy, mainly electricity, is welcomed by people.，Electrification has become an inevitable trend in the construction machinery industry。As electrification begins to accelerate，Lectric mining card using lithium battery as power sources、Electric mining dump trucks began to be active in major mines.，It has become an important part of green mine construction.。

Pure electric mining card

We know that，Electric mine card can replace fuel mine card，In addition to green environmental protection，Another important reason is to save money.。According to incomplete statistics，An electric mining card saves hundreds of thousands of yuan in fuel costs every year.，Two years of fuel savings can even buy a fuel mine card.。The reason why electric mining card saves money，In addition to low maintenance costs,，The price of electricity is far lower than the price of fuel, which is an important reason for people to choose.。So，Does it mean high horsepower?、Is the electric mining card with long endurance more economical than the general electric mining card?？

1、How much electricity is consumed，It is related to load capacity

We know that，How much electricity does a car consume?，It is related to the load capacity.。 That is, under similar working conditions，The more you pull.，The faster the power consumption。A 90-ton electric mining truck and a 105-ton electric mining truck，In the case of similar power and similar working conditions，Who uses electricity faster?？Of course, the 105-ton electric mining card consumes a lot of electricity.。This is also the reason why the large-tonnage electric mining card should be equipped with a high-power motor.。On the one hand，Much more powerful.，The ascent is effortless；On the other hand，Large battery capacity and fast charging，Long endurance。

2、How much electricity is consumed，It is related to working conditions 

What other factors are related to the speed of power consumption of electric mining cards?？It is related to working conditions。Electric mining cards generally work in mines.，It is divided into heavy duty uphill working condition and heavy duty downhill working condition.。Heavy-duty uphill working condition generally means that the working area of the electric mining card is mainly uphill.，That is to say, ore cars loaded with ore are transported from bottom to top.，Empty vehicles return from top to bottom.。Heavy-duty downhill conditions are the opposite.。That is to say, the ore card loaded with ore goes downhill.，Empty return is an uphill section.。The battery capacity of a 90-ton electric mining card is about 423 kilowatt-hours.，1 hour for full charge，You can run six or seven times in a cycle.，In two or three hours.。

Of course，This is only for ordinary working conditions.，As for some special working conditions, it is hard to say.。For example, some complex heavy uphill conditions.，It even needs to be charged four or five times a day.，That is to say, every time you pull it once or twice, you have to charge it.，Conditions like this.，It is obviously not cost-effective to use an electric mining card.。There are also some heavy-duty downhill conditions.，Once charged, it can last for two or three days.，That is to say, the energy recovered when the vehicle is heavily loaded downhill is much higher than the energy consumed when it is unloaded uphill.。That is, some vehicles can be charged once for two or three days.，The reason why some vehicles have to be charged two or three times a day。There is a mine producing and processing nickel ore in Chizhou, Anhui Province.，It is a typical heavy-duty downhill condition.。Someone has done statistics.，The electric mining card that operates there operates every trip.，The energy consumed by no-load uphill is almost equal to the energy recovered by heavy load downhill.！That is to say，Vehicles operating in the mine can run continuously as long as they are fully charged.。The captain in charge of vehicle operation and dispatch told the author.，The mine belongs to the heavy load downhill working condition.，The round-trip distance of a vehicle operation is 1.3-1.5 kilometers，The slope is 8-10°，The vehicle is in 24-hour continuous operation.，A car can run 35 round trips a day.，A car consumes only one kilowatt-hour of electricity a day.。And the company's drivers or operators every 7.-It takes 10 days to resupply electricity to the vehicle.。

3、To save money is to make money

It is well known，The main purpose of the owner to buy an electric mining card is to save money.。First of all, from the purchase cost.，The electric mine card is twice or more than the fuel.。Secondly, from the cost of use.，The cost of burning electricity is much lower than the cost of burning oil.，According to the replacement ratio of three kilowatt-hour electricity and one liter of oil，A 90-ton electric mining card can save more than 2000 yuan in fuel cost a day.。In addition，Compared with fuel oil mining card，Electric mining card reduces engine and gearbox，The cost saved by maintenance alone is more than 30000 yuan a year.。This is calculated，It can save nearly 400000 yuan a year in fuel and maintenance costs.，The extra purchase cost can be recovered in two or two and a half years.。

So，Is there no better solution for heavy load conditions?？The answer, of course, is no.。In order to improve the working efficiency of heavy uphill working condition，Enterprises and related scientific research institutions have been actively exploring.。Hybrid solutions have been introduced successively.、Extended-range solutions, etc.，That is to say, the combination of fuel power and electric power is adopted.，Use of fuel power in complex road conditions，Electric traction is adopted in general working condition or heavy load downhill working condition.。Yuchai's extended-range solution effectively makes up for the shortcomings of the electric mining card.。The new energy mining card with Yuchai range extender has both the advantages of energy saving and consumption reduction of pure electric vehicles and the advantages of rapid refueling of diesel vehicles.，There is no range anxiety for pure electric vehicles.，Not restricted by charging facilities，Can be use without changing that use habit of the user,、Under the condition of continuous operation，Greatly reduce fuel consumption，Cost saving，And reduce carbon emissions.，It is an ideal upgrade solution for users with heavy uphill scenes.。

4、Which users are suitable to buy electric mining cards?

Electric mining card can save a lot of fuel costs and maintenance costs.，It can bring high economic value to the owners every year.；And electricity is clean energy.，Zero emission and zero pollution can be achieved in the use process.，Comply with national energy conservation and emission reduction policies，It can greatly reduce carbon dioxide emissions.，It is completely consistent with the purpose of green mine construction advocated by the state.。

So，Should all mine users buy electric mine cards?？The answer is clearly no.。Professionals suggest，First of all, there should be sufficient quantities.。The greater the amount of work，The more saturated the traffic is，The more obvious the use value of the electric mining card is.；Secondly，It depends on the specific application conditions.。If it is a heavy uphill working condition，Charging too often，The use value of the electric mining card is not too obvious.。If it is a heavy downhill condition，It also depends on the specific working conditions and equipment.，The more it can reflect the use value of the equipment, the better.。

With the development of the times and the progress of society,，Electrification has become a trend in the construction machinery industry.。When choosing an electric mining card，Attention should be paid to the selection of products from regular manufacturers.，Especially the battery、Motor and other core components，When choosing electric products，We should also pay attention to doing what we can.，Otherwise，Keep up with the Joneses，You may get hurt or yourself.。
