On October 11, China Coal Pingshuo Group’s Anjialing coal mine in Shanxi took delivery of an all battery electric XEG220E 200 t class mining truck manufactured by Xiangtan-based XEMC under its Igreencle green energy mining equipment brand. Zhou Jianjun, Chairman of XEMC was present along with Chen Jian, Chairman of China Coal Pingshuo Group. Igreencle is a JV led by XEMC together with SPIC Qiyuan, Zhongke Wieisu (Guangdong) Technology Co Ltd, and Jiaxing Ronghe Dianke Qingshan Equity Investment Partnership. There are now two XEG220E trucks running in China, one with China Coal Pingshuo and the other at another China Coal operation.
XEMC said the XEG220E all electric mining truck “is another innovative example of XEMC’s series of green energy-saving equipment. The advent of new products has given customers more choices in achieving greener production, and XEMC has also won the recognition of customers with excellent product quality and performance.” At the ceremony, China Coal Pingshuo Group also signed a procurement contract with XEMC for 16 sets of 100 t class XEG120E all electric trucks, with a total contract amount of over 100 million yuan, which equates to over US$14 million. Anjialing has already been operating a XEG120E for over a year successfully in tests.
The XEG120E mining truck is also seeing some success elsewhere in the world – two were delivered to AIZ Group in Brazil plus there are six operating with copper mine Chinalco and in Russia, coal miner Stroyservis is running 10 of them.

Igreencle General Manager Jimmy Ji told IM that like the XEG120E, the XEG220E uses lithium iron phosphate (LFP) batteries but a new generation with a longer life cycle. The truck has 2,911 kWh of battery power, uses plug in charging with full charging in 50 minutes and is capable of running for 6 to 8 hours between charges. The XEG220E specifications say the truck can be delivered either with XEMC 5XEG25 or Wabtec 5GEB25 AC electric wheel motors.
It is estimated that each single XEG220E vehicle can reduce CO2 emissions by more than 1,500 t per year, plus can save customers about 5 million yuan a year in operating costs due to the lack of diesel cost but also reduced maintenance. XEMC says that traditional 220 ton diesel mining trucks consume about 4,000 litres of fuel per day, while the XEG220E consumes 12,000 kilowatts of electricity per day, saving nearly 40% in cost.
XEMC adds that in the process of development, to adapt the truck to the road conditions of large open pit mines, it “comprehensively analysed the propulsion system, hydraulic system, ventilation system, air-conditioning system and other systems’ energy consumption; completed the design of the high-voltage distribution box and the high-voltage, high-power power battery pack; plus developed a high-voltage, high-current fast charging system.”
It adds that it is committed to implementing China’s national ‘dual carbon’ goals, continuously advancing on the road of green energy conservation and emissions reduction, innovating in the development of green mine equipment, plus researching and developing new products with larger tonnages and more intelligence, all contributing to the construction of “smart mines, green mines & energy saving mines.”
