Electric Vehicle Revolution Goes Underground With Mine Truck
Electric Vehicle Revolution Goes Underground With Mine Truck Our LFP cells are perfectly suited for Electric underground equipment since their outstanding features: - ultra high dischage current rate: Continuous discharging current up to 15C. - High charge current rate: Continuous charging current up to 6C. -Discharge on very low temperture until -40℃. - Safty. This is LFP cell, much more stable than NCM cell, won`t burn like NCM cell. This is very important to consumer. Our cells passed the most stringent test like Nail penetration and shooting test. -Got "Mining Products Safety Certification". Ensure safty for mining equipment. This will solve 2 very impotant difficults that electrical underground vehicles are facing now: -Safty; -Fast charge. Here reports come from Bloomberg (Bloomberg) — Electric vehicles are reaching global markets far and wide — and deep. Swedish mining equipment maker Epiroc AB now aims to electrify all its underground machines within five years. The manufacturer on Wednesday launched a new range, including what it says is the largest battery-powered vehicle for mining below the Earth’s surface: a 42 ton-capacity truck that can haul blasted rock through narrow tunnels. It’s part of the company’s latest series of mobile excavators, including drill rigs and loaders, designed to cut emissions and lower energy costs for miners. Reducing the use of diesel fuel could have significant cost benefits for the industry: as much as 40 percent of an underground mine’s energy outlay is spent on powering gigantic ventilation systems to remove pollutants from tunnels. The push for electrified mining got a further boost last month from an industry lobby, the International Council on Mining and Metals, which plans to minimize the impact of underground diesel exhaust by 2025. “Next year we will start production of an 18-ton loader and we will start offering medium-sized drill rigs with battery options,” Sami Niiranen, who has been appointed to lead Epiroc’s underground equipment unit, said in Orebro, Sweden. Epiroc, which is using power packs assembled by Northvolt AB, said the upfront cost of buying a battery-powered vehicle would be about twice that of a conventional one. While this is compensated by lower fuel and energy costs down the road, the initial pain could be prohibitive. In a bid to boost sales, Epiroc will lease batteries for its new range of vehicles separately, making the initial outlay only slightly higher than for an equivalent diesel machine. Bigger, Heavier The new electric vehicles are bigger and more powerful than Epiroc’s first models that hit the market in 2016 and are used by customers including Brazilian mining company Nexa Resources. So far, they make up only a small part of sales for Epiroc, which has worked on electrification since 2013. Their best hope are new or expanding mines that aren’t already equipped with expensive ventilation systems. Cross-town Swedish rival Sandvik AB has delivered hundreds of vehicles powered by electric cables, and has plans to launch its own battery-powered machines. The Nordic companies dominate global sales of underground mining equipment, with a combined three quarters of the market. They compete with Caterpillar Inc. and Japan’s Komatsu Ltd. The International Council on Mining and Metals also aims to achieve greenhouse gas-free vehicles for surface mining by 2040. Yet the transition to electric vehicles still has some way to go. Bringing the biggest hauls of rock up steep ramps and out of the ground requires power that existing batteries are ill-equipped to supply. This has led to renewed interest in trolley systems whereby electrified trucks are connected to a power grid with overhead cables. Swedish mining company Boliden AB has a project using Caterpillar trucks and ABB Ltd. power infrastructure to haul ore from Aitik, the country’s largest open pit copper mine.

The advantages of Lithium ion batteries for floor cleaning machine
As the price of lithium batteries continues to fall, lithium batteries have begun to be used in scrubbers. By comparison, lithium batteries already have great advantages. The application of lithium batteries to replace lead-acid batteries in scrubbers is becoming more and more popular. There advantages as follows: ·Cycle life more than 3000 cycles, long service life, and do not need change battery during the entire service life of ground clean machine. ·Flexible charge is available, such as charge during change water or rest. Don't worry about forgetting to charge or running out of battery. ·Maintenance free, Don't worry about charging during long time of storage. ·The price of the lithium ion battery is more competitive in the entire service life of the ground clean machine. Comparison of lead-acid and lithium batteries Item Lead acid battery Lithium ion battery（LFP） Service life 300-500 cycles, about 2 year in average 3000 cycles, same service life with machine Charge 8-10 hours needed to full charge. Usually charge for whole night after end of work. Frequent charge will shorten it`s service time. Only 1-2 hours needed to full charge. Flexible charge is available, such as charge during change water or rest. Frequent charge does not affect its service time. Working The voltage gradually decreases, the motor power gradually decreases, and the work effect will decrease in the later stage, such as the cleaning is not clean. The voltage is stable and the working effect will not decrease. Energy output efficiency About 75% About 98% Unit price Assume 1 About 2 Total price of battery in whole service life of the machine Generally change the battery 3 times, the price is 3 Solution 1. The capacity is 50% of the lead-acid battery capacity, which is equivalent to 65% of the energy output of the lead-acid battery. It can be charged at any time and without affecting actual use, the price is 1. The entire life cycle cost is 1/3 of the lead-acid battery. Solution2. The capacity is 80% of the lead-acid battery capacity, which works the same as a lead-acid battery, and the price is 1.6. The entire life cycle cost is about 50% of the lead-acid battery. Maintenance Maintenance is necessary. Charge every 1-3 months is necessary under long time of storage. Maintenance is unnecessary. Self-discharge less than 15% one year, and do not need charge during storage for one year.
