BorretonBRT105E-700kWhThe pure electric mining card has been launched since 2021.，It helps many mining enterprises to achieve the goal of energy saving and carbon reduction in heavy uphill scenes.，Realize the unification of economic benefit and environmental benefit。As a pure electric mining card，Why doesn't it overheat when it keeps going uphill with a heavy load?？Why 700?kWhThe design of？Why can I charge 600 kilowatt-hours in an hour?？Why is it launched by the new power company of construction machinery?？I believe many friends will be curious.，Let Dr. Ma explain it to you today.~

Heavy Load Up-Ramp Cost Demand

Boreton's first mining card is a pure electric mining card developed for heavy-duty downhill scenarios such as cement mines.，Help users reduce costs。Today, many vehicles have exceeded 100000 kilometers.，Still operating normally in the mine，Continuously help users reduce carbon and cost。

More scenes of heavy load uphill on the mine，Fuel consumption is also higher，Customers have a stronger demand for cost reduction and carbon reduction.。Therefore, Boreton uses the mineral card products developed in the early stage.，Invite multiple users of heavy-duty uphill scenes to carry out trial，Collect the data and user feedback of the product in the heavy uphill scenario。

Practical discovery，Mine cards developed specifically for heavy downgrades when used in heavy uphill scenarios，Insufficient endurance，Charging frequency has a greater impact on production efficiency，Reduces economic benefit。Therefore，After fully understanding the actual requirements，Boreton Begins to Develop a New Pure Electric Mining Card for Heavy-Duty Uphill Scenes。

Why 700?kWh?

Through the observation of the usage habits of mine customers，Borreton engineers found，Mine customers are under the production rhythm of 24 hours and two shifts.，Shift change、Lunch break or night meal period，Everyone has to rest for about an hour.，The actual number of working hours per day of the mining card is about 20-21h，That means an average of 5hThere will be 1 left and right.hLeft and right gaps。

According to the actual production habits of users and the power consumption data of different slopes collected in the early stage.，Combined with the current mainstream slope level of mines around the world,，And vehicle design、Manufacturing costs、Multiple factors such as life cycle economy，Boreton engineers finally settled on the 700.kWhDevelopment scheme of mining card，Coordinated energy-saving strategy with vehicle control，Meet the goal of most heavy-duty uphill scenarios lasting more than 5 hours on a single charge。

After years of development and validation work，Boreton 700kWhSuccessful delivery of pure electric mining card to users，It meets the actual production needs of users.。At the mine site of Zijin Mining in Xinjiang，Measured at an average slope of 10%Under the working condition of left and right pure heavy load uphill，BRT105EWorks on a single charge 5.5hLeft and right，Make the most of your lunch break、Energy supplement during shift change，In time“Full blood”Engage in a new battle。

How to relieve your worries，Only innovation

In view of the actual demand for power in the heavy uphill scene，Borreton has developed a completely new powertrain，It is not only more stable under continuous heavy load conditions.，The rated 500 is also achievedkW、Up to 800kWSuper power output，Converted to horsepower，More than 1000.，Even facing 30%The slope is also fearless.，Not only can it be pulled.，You can still walk fast.，Ffectively improve transportation efficiency。

The spirit and achievements of Borreton's independent innovation have been recognized by the government and experts.，The electric drive system has won the top ten independent innovations of Shanghai's high-tech achievements transformation projects in 2022.。It is worth mentioning that，This is the selection of all industries in Shanghai.，The innovative attributes of the Borreton electric drive system are evident。

Outside the parameter table

Develop a 700kWhPure electric mining card is not simply to increase the number of batteries.，It is a systematic project.，It can be said to affect the whole body.。

First，Other things being equal，The battery charge has increased，The charging time will be extended accordingly.。Long charging time will also affect production.，Therefore, engineers must solve the problem of charging time and efficiency.。

Subject to physical limits and regulatory requirement，And the cost of accessories、Charging pile cost factor，After repeated calculations and experiments,，Layout scheme of 4 branches selected by Boreton engineer，For the battery system、High voltage module、Unified calibration of charging piles and other aspects，Achieved 4 shots-600kWHigh-power charging，Design time 1.2 hours to complete charging。During actual operation，Recharge during lunch break or shift change，There is usually a certain amount of electricity left.，Therefore, the actual charging time of customers is mainly concentrated in 40 minutes.-60 minutes。

Secondly，Vehicle discharge、The charging power is greatly increased.，This is followed by a large increase in system heat，A new thermal management system is necessary.。If the thermal management technology is not up to standard，It's easy to overheat.，The system will limit the power output，It will seriously affect work efficiency.，And in winter, it is easy to cause the battery to fail to work properly due to the low temperature of the battery.。

Through the unremitting efforts of the team of Boreton Sandian，For the Boreton 700kWhThe well-designed thermal management system of pure electric mining card has withstood the test of actual combat.。Summer mines in Xinjiang，Approaching 40 above zero℃，High altitude areas in northern Inner Mongolia，Close to below zero-35℃，Borreton Pure Electric Mine Cards Take It Easy，Live up to the trust of customers。（Click to view《Boreton 700kWhPure Electric Mine Card Expedition Day 115：The attendance rate is 99.78%》）

Why Borreton？

Boreton is a new power enterprise of new energy construction machinery.，With a new mission and role.，No longer satisfied with the single role of equipment manufacturer，Instead, the evolution is defined as a green transport service provider.，Focus on the actual effect of green production for users，So there is determination、Motivated to develop new products，To solve the problems encountered by users in actual production.。

 

The head of the Boreton Mining Card Project said.，700kWhPure electric mining card can be successfully developed，One of the key factors is the strategic support from the top of the company.，Provide us with sufficient R & D resources，Including funds、Personnel and other support。When the project was first established，The prospect of mining card electrification is far less clear than now.，In the process, it also encountered adverse factors such as the soaring price of lithium battery raw materials.，But the company never gave up.，Always be as supportive as possible，Let us successfully complete the research and development and verification work.，Seize the market opportunities。

It is possible that the investment return cycle of a certain model is longer.，But what Borreton calculated was“Green transport capacity service”The general ledger，You can't go over the first four steamed buns and eat the fifth one directly.。Heavy-duty uphill special vehicle is an important link in the green production scheme.，On this basis，Borreton's Green Power Applications、Driverless、Smart mines will be better developed and applied.，To get closer to our mission.。

700kWhPure electric mining card，It is just a small node on the innovation road of Boreton.。Remain true to our original aspiration，Forge ahead，More works，Still on the way。
