A More Profitable Electric Excavator - JGM Launches a New Mobile Charging Solution for Electric Excavators
2026-09-22
Author:
A 50‑tonne electric excavator consumes about 140 kWh per hour. While mining trucks can support battery swapping, once an excavator leaves the working face to recharge, it not only cuts into its own productivity but also disrupts the entire loading‑and‑hauling rhythm. So how do you bring the power to the equipment, rather than making the equipment stop and wait for power?
To tackle this industry‑wide challenge, JGM has launched the VE800 Mobile Power Supplier – delivering power directly to the loading face.
Power Follows the Equipment – A New Way to Charge at the Loading Face
Designed for the complex conditions of mine sites, the VE800 Mobile Power Supplier systematically addresses the key difficulties of mobile recharging in loading operations across three dimensions: site adaptability, energy assurance, and digital control.
Mine working faces are notoriously tough – littered with crushed rock and slag, riddled with steep ramps and uneven ground. The VE800 is equipped with a full‑time all‑wheel‑drive engineering chassis and an oscillating front axle, delivering outstanding climbing and obstacle‑crossing capability with superior rough‑terrain mobility. It can reach the excavator right at the working face and, via a dedicated charging interface, supply power on the spot – truly enabling “power wherever the excavator goes.” Think of it as a “giant mobile power bank” for mining operations.
Leveraging CTB (cell‑to‑body) vehicle‑storage integrated battery technology, the VE series supports flexible battery capacity configurations, with a maximum capacity of 3,200 kWh – enough to sustain long, continuous operation for large electric excavators. The built‑in smart digital management system monitors equipment status in real time, enabling remote inspection and intelligent early warning, making the entire charging process safer, more efficient, and smarter, while ensuring round‑the‑clock mine production.
Proven in the Field: Breakthrough – Over 20 Hours of Continuous Operation
Can this mobile charging solution withstand the extreme conditions of real mining operations? At a state‑owned mine in Inner Mongolia, a collaborative model was deployed: “1 x 50‑tonne electric excavator + 2 x VE800 Mobile Charging Vehicles.” On‑site measured data showed that the excavator consumes 140 kWh per hour, and a single VE800 can support 5 hours of continuous operation. With the two charging vehicles taking turns in a relay – alternating between charging and shuttling – they stably sustain the excavator for over 20 hours of continuous daily operation, ensuring uninterrupted production and non‑stop power supply.
Cutting downtime directly translates to higher production efficiency. Comparative field measurements show that with the VE800, the comprehensive energy cost for the same‑class electric excavator drops by approximately 60% compared to a diesel‑powered unit. The project manager commented: “Previously, when the excavator had to stop for recharging, it would lose at least one to two hours each time, completely throwing off the production schedule. Now, with the VE800 coming right to the working face, the excavator doesn’t need to stop. We’re extracting hundreds more tonnes of ore per day, production coordination is smoother, and operating costs are down.”
Moreover, by tapping into the mine’s high‑quality clean energy sources – such as solar PV and wind power – the VE800 delivers green electricity straight to the extraction frontline. To date, this mine has already reduced CO₂ emissions by approximately 140 tonnes, achieving both economic gains and green development goals.
From Haulage to Extraction – Further Unlocking the Mine Electrification Chain
The deployment of the VE800 Mobile Charging Vehicle in mine operations provides a stable recharging solution for electrifying the loading and extraction link.
In the broader push toward full‑process mine electrification, the haulage segment is gradually adopting battery‑swapping at scale. However, the loading and extraction segment – characterized by fixed‑position operation, high power demand, and restricted recharging radius – has long been one of the most challenging links to electrify. The real‑world application of the VE800 now opens a new pathway for recharging extraction equipment.
As the mobile‑charging model is rolled out across more mine sites, ensuring a steady supply of green power at the loading face, mine electrification is extending from isolated transport applications to core production processes – and the horizon for green, smart mining continues to expand.
