Zijin Longking's ZL230E Puts 230 Tonnes on Battery Power
Chinese equipment maker Zijin Longking has added the ZL230E to its electric mining fleet — a 230-tonne-payload haul truck with a battery said to reach 90% charge in 25 minutes.

Zijin Longking has unveiled the ZL230E, a battery-electric mining dump truck built to carry up to 230 tonnes of material, extending a product line the Chinese equipment maker has been steadily electrifying. The company says the truck’s battery charges to 90 per cent in 25 minutes — the single specification that matters most for whether a machine of this size can hold a place in a 24-hour haul cycle.
The launch was reported by electrive, which describes the ZL230E as a 350 tonne class machine — a reference to gross vehicle weight rather than payload, the convention used across the ultra-class haulage segment.
Why the charging window is the whole argument
Diesel haul trucks are refuelled in minutes and run around the clock. Every hour a battery truck spends plugged in is an hour it is not moving rock, and in an open pit where the fleet is sized to a production plan, that idle time is the cost that kills the business case. A 25-minute window to 90 per cent is the kind of figure that lets a mine planner treat charging as an extension of an existing shift-change or crib break rather than as a new category of downtime.
It is also, on its face, a very demanding claim. Pushing that much energy into a pack that quickly implies serious charging infrastructure at the pit — high-power connections, cooling, and grid capacity at a site that may be a long way from a substation. The truck is only half the purchase. Mines evaluating machines in this class are effectively being asked to buy an electrical system as well, and the payback maths depends as much on the price of that infrastructure as on the sticker price of the vehicle.
What 230 tonnes means in the haulage hierarchy
Payload is the language of mine haulage. A fleet is specified by how many tonnes each truck moves per cycle and how many cycles it completes per shift, and everything from ramp gradients to shovel bucket size is designed around that number. Putting a 230-tonne payload machine on batteries places Zijin Longking in the ultra-class tier — the trucks that do the heavy lifting at large copper, iron ore and gold operations, not the smaller articulated units where electrification arrived first.
That matters because the smaller end of the market was always the easier engineering problem. Lighter machines, shorter hauls, smaller packs. The ultra-class segment is where diesel has been hardest to displace, and where the global equipment makers — Caterpillar, Komatsu, XCMG and others — have concentrated their own electric and trolley-assist programmes. Each new entrant at this size narrows the field of excuses for mines that have set decarbonisation targets and then discovered the equipment did not exist.
The battery demand nobody counts in EV forecasts
Mining haulage sits awkwardly in battery demand models. It is not automotive, not grid storage, and the unit volumes are tiny compared with passenger cars. But the pack sizes are enormous. A single ultra-class haul truck carries a battery orders of magnitude larger than a family EV, and a large pit runs dozens of them. Convert a meaningful share of the world’s ultra-class fleet and the cell demand becomes material — and it is demand with an unusual duty profile: deep, repeated cycling, high charge rates, punishing ambient conditions, and a customer who measures success in tonnes moved rather than range.
That duty cycle favours chemistries built for cycle life and thermal tolerance over those optimised for energy density, which is one reason Chinese cell makers — dominant in lithium iron phosphate — are well positioned to supply this segment. It also creates a feedback loop worth watching. Mining companies are among the largest industrial buyers of the metals that go into batteries, and a mine that electrifies its haul fleet becomes a consumer of the lithium, nickel and graphite supply chain it also feeds.
The vertical-integration angle
Zijin Longking’s position is unusual. The Zijin name is attached to one of China’s largest mining groups, which means an equipment arm building electric haul trucks has a potential in-house customer base of operating pits — a testing ground most equipment vendors have to negotiate for. Machines of this size are rarely bought on a spec sheet; they are bought after years of watching someone else run them. Having captive sites to accumulate operating hours is a genuine commercial advantage in a market where reliability data is the currency.
Machines of this size are rarely bought on a spec sheet; they are bought after years of watching someone else run them.
What is not yet public is the commercial detail that would let a buyer outside China assess the machine: pack capacity, energy consumption per tonne-kilometre, expected pack life, service network, and price. Those are the numbers that determine whether the ZL230E displaces diesel on economics or only on emissions accounting.
What to watch from here
Three things will tell the story over the next several quarters. First, whether the 25-minute charging figure holds up on a working ramp rather than a demonstration pad — grade, altitude, temperature and payload all conspire against laboratory numbers. Second, whether orders come from outside the Zijin group, which is the test of whether this is a product or a captive programme. Third, whether the fast-charging infrastructure needed to support it becomes a standardised offering or remains a bespoke engineering project priced per site.
The broader market backdrop has been supportive of risk assets: the S&P 500 tracker (NYSEARCA: SPY) traded at $765.91, up 0.43% on the day, with the Nasdaq 100 proxy (NASDAQ: QQQ) at $713.38, up 0.34%, and the Dow tracker (NYSEARCA: DIA) at $532.26, up 0.90%, as of the last trade at 18:55 GMT on 21 August 2026. That is the environment into which heavy-industry electrification announcements are landing — one where capital for long-payback equipment programmes is comparatively available.
For the battery supply chain, the significance of a machine like the ZL230E is not the individual truck. It is the signal that the hardest, heaviest corner of industrial transport now has multiple credible electric options, and that the constraint is shifting from whether the vehicle exists to whether the pit can be wired to feed it.

Frequently asked questions
What is the ZL230E?
The ZL230E is a battery-electric mining dump truck unveiled by Zijin Longking. It is designed to carry up to 230 tonnes of material per load and is described as a 350 tonne class machine, a figure that refers to gross vehicle weight rather than payload. It is the latest addition to the company’s expanding range of electric mining vehicles.
How fast does the ZL230E charge?
Zijin Longking says the truck’s battery can be charged to 90 per cent in 25 minutes. That figure is central to the machine’s commercial case, because haul trucks in open-pit mines are expected to run near-continuously and any extended charging stop directly reduces the tonnes moved per shift.
Why does payload matter for mining trucks?
Payload is how mine fleets are specified. Production plans are built around how many tonnes each truck carries per cycle and how many cycles it completes per shift, with ramp design and shovel sizing following from that. A 230-tonne payload places the ZL230E in the ultra-class tier used at large copper, iron ore and gold operations.
Who else builds electric mining haul trucks?
The major global equipment makers, including Caterpillar, Komatsu and XCMG, all run electric or trolley-assist haulage programmes aimed at the ultra-class segment. Electrification arrived first in smaller articulated machines, where shorter hauls and lighter loads made the engineering problem easier, and has been slower to reach the largest trucks.
What does electric mining haulage mean for battery demand?
Unit volumes are small compared with passenger cars, but the packs are vastly larger, so a converted fleet at a single large pit represents substantial cell demand. The duty cycle involves deep repeated cycling, high charge rates and harsh conditions, favouring chemistries built for cycle life and thermal tolerance rather than maximum energy density.
What is the main obstacle to adopting trucks like this?
Charging infrastructure. Delivering enough power to bring a pack of this size to 90 per cent in 25 minutes requires high-capacity electrical connections, cooling and grid access at sites that are often remote. Buyers are effectively purchasing an electrical system alongside the vehicle, and that cost shapes the payback calculation.
