Wolong Electric & AEAUTO mining truck conversions: cost and retrofit notes for fleets
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
Wolong Electric and AEAUTO have entered China’s fast-growing diesel-to-electric mining truck conversion market, joining established players such as HATL (Fujian Hongda Contemporary Amperex Technology Co Ltd) and Huigong Group’s Xingdong Lithium Battery Technology Co Ltd (XDLE). The move expands the supply base for high-capacity lithium battery systems and electric drivetrains tailored to large haul trucks operating in Chinese open pits. For mine operators, increased competition in conversion packages should sharpen pricing and accelerate retrofits of existing diesel fleets rather than full replacement purchases.
Technical Brief
- Systems will need to interface with existing mechanical frames, suspensions and hydraulic dump bodies without major structural rework.
- Control architecture must replace diesel engine ECUs with integrated battery management and traction inverter systems.
- Regenerative braking on long downhill hauls becomes a key design feature for energy recovery and brake wear reduction.
- Thermal management of large-format lithium packs is critical under high ambient temperatures typical of Chinese open pits.
- Workshop conversion workflows will hinge on minimising truck downtime versus full replacement, affecting fleet availability calculations.
- For other mining fleets, retrofit economics will depend on diesel price, grid power tariffs and remaining truck life.
Our Take
China is one of the most frequently appearing countries in our Mining sustainability-tagged pieces, signalling that Wolong Electric and AEAUTO are entering a domestic market where mine operators are already under pressure to decarbonise large mobile fleets.
With no specific commodities tied to this announcement, the diesel-to-electric conversion push by Wolong Electric and AEAUTO in China is likely targeting generic haulage applications, which could make the solution attractive for contractors operating across multiple ore types and regions.
Several other China-based equipment and battery suppliers in our database are focusing on underground or smaller-scale electric vehicles, so a move by Wolong Electric and AEAUTO into large mining truck conversions would fill a gap at the high-tonnage end of the fleet spectrum.
