The TZ3V electric dump truck is finding a home in Kazakhstan's copper belt, and in the steppe mines it proves that a cold-climate EV truck can match diesel on haul-cycle cost while cutting the ventilation and fuel burdens of surface mining. This review covers the 424 kWh battery, cold-start performance, and cost per tonne hauled.
Copper operations in Kazakhstan run long surface hauls in a climate that swings from -30°C winters to +35°C summers. The TZ3V's predictable electric drivetrain removes diesel fuel transport to remote sites, a major logistics cost in the steppe, and cuts the ventilation load where haul roads pass near enclosed areas.
Mines also value the quiet, low-vibration operation that reduces operator fatigue over a 12-hour shift, and the instant torque that helps loaded trucks pull away from the shovel without the lag of a diesel that has been idling in the cold.

The 424 kWh pack and 420 kW motor give the TZ3V the muscle for copper haul cycles while delivering 220-280 km of practical range. The liquid-cooled CATL LFP pack includes heating so cold-start capability is built in rather than bolted on.
Winter is the real test for any EV truck in Kazakhstan. The TZ3V's pack heating brings cells to operating temperature on grid power before the shift, so the first haul leaves with full available range. LFP retains a usable fraction of capacity at -20°C, and the liquid loop keeps the pack in its efficient window even when ambient drops far lower.
Mining fleets price everything per tonne moved. Diesel dump trucks burn heavily on grade and idle at the shovel; the TZ3V's energy cost per tonne is lower because electricity is cheaper than diesel haulage to remote sites and regeneration recovers descent energy. Over a 4,500-cycle pack life, the per-tonne figure stays flat and forecastable.
The removal of fuel convoys to remote pits is a logistics win on its own. Mines that currently truck diesel hundreds of kilometers can instead run a power line and charge on site, cutting both cost and the safety risk of fuel storage in isolated terrain.
Kazakhstan's copper sites are remote and cold, and the TZ3V's heated, low-vibration cab keeps operators alert through 12-hour shifts. Without a diesel engine bay radiating heat and fumes into the cabin, the HVAC load is lower and the air is cleaner, which quietly improves safety and reduces turnover on a duty cycle where driver retention is a real cost. The quiet drivetrain also lets crews communicate on the haul road.
A mine far from a service center cannot afford frequent diesel engine work, and the TZ3V removes the engine, exhaust, and after-treatment from the failure list. The sealed electric drivetrain resists the dust and grit of open-pit haul roads, and the liquid-cooled loop protects the pack where a conversion would overheat. Planned maintenance is dominated by tires, brakes, and suspension rather than powertrain rebuilds.
Mines can run a power line to the pit and charge on site rather than trucking diesel hundreds of kilometers, which cuts both cost and the safety risk of fuel storage in isolated terrain. The TZ3V's 20-80% window of 45-90 minutes on 240 kW or 360 kW DC units fits naturally into the shovel-to-dump cycle, and the shared Dongfeng EV charger standard serves any other electric units on site.
Where haul roads pass near enclosed or semi-enclosed areas, removing diesel exhaust improves ventilation load and worker safety, a benefit that grows where regulations tighten. The TZ3V's zero tailpipe emission at the point of use makes it a candidate for mixed surface-and-tunnel duty that a diesel dump would complicate with fumes.
Shaanxi Fenghan Trading ships cold-climate spare-parts kits and trains mine crews on the electric drivetrain and charger, so the site is not dependent on long supply lines for routine service. Because the platform is shared with the TZ5E electric dump truck, a mixed mine fleet consolidates inventory and training into one program.
Extreme cold, remote sites, and hard two-shift cycling make LFP the only sensible chemistry here: safe, long-lived, and tolerant of temperature swings. The warranty is not a marketing number but a realistic expectation for an asset that cannot afford an unexpected pack failure halfway through a mining contract.
On a typical Kazakh copper haul of 2-4 km per leg, the TZ3V completes dozens of loaded cycles per shift, and the 424 kWh pack covers a full shift before a midday top-up. The 420 kW motor pulls the loaded body up the ramp without the lag of a diesel that has been idling in the cold, and regenerative braking on the empty return recovers meaningful energy. Fleet engineers track per-pack cycles to prove the 4,500-cycle warranty is being used, not wasted.
Remote steppe mines cannot afford a breakdown, and the TZ3V's sealed electric drivetrain removes the diesel failure modes that strand loads: no fuel gelling, no glow-plug faults, no turbo lag on a cold start. The quiet operation also lets crews hear warnings and each other on the haul road, and the absence of exhaust at the shovel improves air quality where operators spend whole shifts loading.
Open-pit haul roads throw fine, abrasive dust that clogs diesel intakes and shortens engine life; the TZ3V's sealed electric components resist that grit, and the liquid-cooled loop is filtered and protected so the pack and inverter stay clean. The result is longer service intervals and fewer unplanned stops on a duty cycle where every stopped truck is a bottleneck at the shovel.
When the removed diesel fuel convoy, the lower maintenance, and the regeneration are stacked, the TZ3V's cost per tonne moved is structurally lower than a diesel dump on the same copper haul. Over a multi-year mine life that gap compounds, and because the energy rate is fixed rather than tied to diesel delivery cost, the per-tonne figure is forecastable for contract bidding.
