With the country“Double Carbon”The continuous deepening of strategic objectives，New energy mine cars are taking the lead in the field of mine construction.。Among，Represented by pure electric“New forces”，Zhengyi“On a roll”The trend is leading the transformation of mining Vehicle industry.，It has increasingly become a strong support for the green and sustainable development of China's mining industry.。
Tongli Heavy Industry is a leading enterprise in the off-highway transportation equipment industry.，Always insist on exploring in practice.,Move forward in thinking，Become one of the earliest enterprises in the industry to develop electric mining cards。It began to develop pure electric wide-body dump Trucks in 2014.，At present, new energy products cover 40 tons.、60-ton and 70-ton，There is a rechargeable version、Side displacement plate、After the replacement of the plate、Driverless version and many other products，A total of more than 500 new energy off-highway wide-body dump Trucks are operating in more than 30 mines.。
The first batchTOP50“New Energy Gold Award”
In April this year，Guided by the National Center for Quality Supervision and Inspection of Construction Machinery，《Construction Machinery and Maintenance》Sponsored by the magazine“2022 China Construction Machinery Product of the Year TOP50 Selection ”，First launched at the same time“New Energy Gold Award”Selection activities。
The selection is for 2020、2021年Pure electric Vehicles listed and sold in China、Hydrogen Energy and Hybrid⼒And other new energy construction machinery products。Tongli Heavy IndustriesTLEThe 105 pure electric off-highway wide-body dump Truck is screened layer by layer.、Expert and customer review，Won the first batch of construction machinery industryTOP50“New Energy Gold Award”Product title。
Reveal the secret“New Energy Gold Award”Product strength
In the near future，Experts from the National Construction Machinery Quality Inspection and Testing Center for Tongli Heavy IndustriesTLE105 products have been professionally tested，Mainly from the professional testing of energy efficiency and noise，The performance of the product was evaluated objectively.，Validate Gold Award Product Value with Data。

Comfortable and low noise
The noise test is obtained from“External radiated noise”And“Noise in the driver's ear”Two parts，Idling at low speed according to the setting of the whole machine、Test of stationary working cycle and driving condition，Calculate a composite value。The final noise determination composite result is：Outboard emission sound power level 99 dB，Emitted sound pressure level at driver's position 73 dB。The numerical value belongs to the comfort range of normal sound reception of human ears.，Relative to the noise of oil Vehicles, it has obvious advantages in driving comfort.。

Energy saving and environmental protection
This energy efficiency test，Under full load，The staff determined after the preliminary road running test and analysis.TLEThe best economic speed of 105 is 15km/h。According to the test requirements and daily work usage，Charge to 100%After the amount of electricity, carry out 40 at the most economical speed.kmA road race experiment.。
According to the final test results,，Complete 40 at economic speedkmDistanceTLETotal power consumption of 105 is 194 degrees，Calculated according to standard electricity price（0.Seven yuan/Degree）It costs 135 yuan，Save 60% of energy cost compared with traditional oil vehicles～95%。This is the result obtained only on a flat test field.，It does not involve the energy recovery of heavy downhill.。
Under heavy load downhill working condition，TLE105 High energy recovery，Low single cycle power consumption，According to incomplete statisticsTLE105 products to achieve carbon emission reduction in 2021 27kt。

Reduce cost and increase efficiency
When Tongli Heavy Industry's pure electric off-highway wide-body Dump Truck is going uphill without load，Just drive the empty car up the hill.，Most of the electrical energy is converted into the gravitational potential energy of the vehicle.；When going downhill with full load，The gravitational potential energy of the vehicle is converted into kinetic energy，Drive the main motor to generate electricity，At the same time, the kinetic energy is converted into electric energy and stored in the battery.，Consumes the recovered electric energy when the vehicle is unloaded and goes up the slope and is heavily loaded and goes down the slope，Reduce external power supply。Ideally, no charging is required.，Reduction in fuel expenditure by 90 percent%Above，And that three-power system is maintenance-free.，Significant reduction in operating costs。

Efficiency improvement
TLE105 Pure electric off-highway wide-body Dump Truck with a single load of 70T，High operation efficiency of double motor，Equipped with Tongli Heavy Industry Co., Ltd.“A great power weighs heavily” Of the title“Gold chassis”，Is currently on the market to carry 70TThe pure electric wide-body Dump Truck above the level is the first product to run in batches.。It not only has a large bearing capacity、Meanwhile, the failure rate is reduced by 20 percent%～30%，Attendance remains at 90 percent%Above，The effective working time of the user is improved。

High adaptability
Tongli Heavy Industry has a wide range of application scenarios for pure electric off-highway wide-body dump trucks.，At an altitude of 5,500 meters，High and cold、High heat and other application scenarios have completed product verification，At the same time, product verification has also been carried out in places with more rain in the south.。It has been achieved in 17 provinces.，Applications in more than 30 mines。Grassland、Snow Mountain、Gobi、There are pure trams running by Tongli Heavy Industries in the tidal wetlands.。
Pure Electric Wide-body Vehicle in Accelerated Development
With“Double Carbon”Strategy and promotion of national new energy policy，In the near future，It is the general trend for pure electric wide-body vehicles to replace fuel wide-body vehicles.，This has become the consensus of the industry.。Although the current R & D investment of pure electric wide-body vehicle products is in the development stage.，However, with the continuous breakthroughs in technology and the gradual maturity of the pure electric wide-body vehicle industry chain,，This market segment is bound to usher in“Outbreak period”。In 2022, the penetration rate of Tongli Heavy Industry's pure electric off-highway wide-body dump truck is 5%Left and right，By the end of the year, the total sales will exceed 1000 units.。Tongli Heavy Industries will rely on professional off-road vehicle R & D and manufacturing accumulation.，Continue to lead the industry forward，Tongli Heavy Industries not only has the first-mover advantage and technical reserves.，It has a deep accumulation in the understanding of product application scenarios.。
Tongli Heavy Industries is breaking through the vehicle controller.（VCU）Independent research and development，After the breakthrough of this key technical point,，Autonomy can be fully realized in subsequent application scenarios.，And the adjustment of the software system can be used to match different application scenarios.，Tailored to different operating environments，To better meet the individual needs of different operating environments。
“Strive to achieve carbon peak by 2030，Carbon neutral by 2060。”In the changing times，Help to achieve carbon peak、Carbon neutral target achieved，It is the mission entrusted to enterprises by the times.，It is also the responsibility that enterprises should shoulder.。Tongli Heavy Industries will continue to lead the industry development，In green、Economy、Continuous breakthroughs on the basis of high efficiency，Provide strong support for the transformation of construction machinery and equipment，To provide the same scheme and guarantee for the construction of green mines。
