The TZ3V 600 kWh electric dump truck is engineered for the high Andes, where a conventional diesel hauler loses roughly 10 percent of its power for every 1,000 m of elevation. At a Peruvian copper mine working at 4,000 m that is a 40 percent derate, forcing operators to overload the turbo and burn more fuel just to keep the same payload moving. The TZ3V is an electric truck with no combustion breathing to lose, so its 510 kW motor delivers full torque from sea level to the pit crest.
Altitude also thins the air that cools a diesel intercooler, so thermal derating stacks on top of the power loss. The TZ3V's liquid-cooled CATL LFP pack and motor run on a closed loop independent of ambient oxygen, holding cell temperature in the 25 to 35 °C window even when the mine sits under strong Andean sun at 4,000 m.
The TZ3V is an 8x4 rigid dump with a 600 kWh CATL LFP battery and a 510 kW drive motor. That capacity supports multiple haul cycles per shift and fast opportunity charging between loads. The table below is the spec sheet Peruvian buyers quote against when retiring older diesel tippers.
| Parameter | TZ3V Value |
|---|---|
| Battery capacity | 600 kWh CATL LFP, liquid-cooled |
| Drive motor | 510 kW permanent-magnet motor |
| Chassis layout | 8x4 rigid dump, 40 to 50 t payload |
| Body volume | 18 to 22 m3 V-shaped mine body |
| Certified range | 260 to 320 km per charge |
| DC fast charge | 240 / 360 kW (20 to 80 percent in 60 to 90 min) |
| Battery warranty | 8 years / 4,500 cycles |
| FOB price range | USD 150,000 to 180,000 |
A turbo diesel rated at 400 kW at sea level produces about 240 kW at 4,000 m after the 40 percent air-density penalty. The TZ3V holds its 510 kW regardless of elevation, so on a steep pit ramp it out-climbs the diesel even before regen is counted. The table shows effective available power on a representative ramp grade.
| Elevation | Diesel available kW | TZ3V available kW |
|---|---|---|
| Sea level | 400 kW | 510 kW |
| 2,000 m | 320 kW | 510 kW |
| 4,000 m | 240 kW | 510 kW |
Because the ramp climb is where most energy is spent, the TZ3V's flat power curve means shorter cycle times and more loads per shift than a derated diesel of similar rating.
Most mine haul roads are a climb up empty and a descent loaded, which is exactly where regen shines. On the loaded descent the TZ3V recovers 15 to 25 percent of the energy used on the climb, feeding it back to the pack through the liquid-cooled inverter. Over a 3 km loaded descent at 6 percent grade the truck can recover 30 to 45 kWh per trip, cutting the net energy per cycle dramatically.
Peruvian mines run continuous shifts, so the TZ3V charges during the loader queue and the blast window rather than overnight. A 360 kW DC unit at the shovel adds 20 to 80 percent in about 60 minutes, enough to cover the next block of cycles. Fenghan can site a containerized charger with its own transformer so the mine avoids a substation upgrade.
Where grid power is unreliable, a solar plus battery micro-grid at the depot keeps chargers online, and the TZ3V's 600 kWh pack itself acts as a buffer that smooths the camp's own demand peaks.
Altitude sickness is a real productivity risk for diesel operators because the cab fills with fumes and the thin air saps concentration. The TZ3V emits no exhaust in the pit, so cab air stays clean and the site's ambient CO and NOx fall. That improves permit standing with Peruvian environmental authorities and reduces respiratory claims.
Diesel at a remote Andean mine can cost USD 1.2 to 1.5 per liter after the haul up the cordillera. A TZ3V running 200 km per day on 1.4 kWh per km at USD 0.12 per kWh spends about USD 34 per day on energy against USD 320 to 400 per day for an equivalent diesel. Over a 6-year mine life the energy saving alone can exceed the FOB price of the truck.
| Cost (6 yr / 360,000 km) | Diesel tipper | TZ3V EV |
|---|---|---|
| Fuel / energy | USD 1.30M | USD 0.15M |
| Maintenance | USD 0.28M | USD 0.14M |
| Battery (pro-rata) | n/a | USD 0.20M |
| Total | USD 1.58M | USD 0.49M |
Underground and open-pit mines in Peru must control diesel particulate at the face, and replacing haul trucks with the TZ3V cuts site PM and NOx to near zero. That reduces the required ventilation volume in decline access and lowers the mine's fan energy bill, a secondary saving that compounds with the direct fuel saving. Permit renewals with the Peruvian Ministry of Energy and Mines now favor operations that can show a declining emissions curve, so the TZ3V also eases the social-license conversation with nearby communities that live downwind of the pit.
A pit moving 8,000 t per day with a 22 t payload per truck needs roughly 360 loaded cycles. Four TZ3V units, each running 18 to 24 cycles per shift on a 600 kWh charge, cover that volume with one charger and a staggered break schedule. The table below shows a representative shift energy plan for a four-truck fleet working a single bench.
| Metric | 4-truck pit fleet |
|---|---|
| Daily payload | 8,000 t |
| Cycles per truck per shift | 18 to 24 |
| Energy per cycle | 22 to 28 kWh |
| Charger needed | 1 x 360 kW DC |
| Daily fleet energy | 3.2 to 4.0 MWh |
The TZ3V has no engine oil, no diesel filters, and no after-treatment to service, so scheduled maintenance drops to tires, brakes, and chassis lube points. Brake wear is minimal because regen does most of the slowing on the loaded descent. Fenghan stocks motor and inverter spares at a Lima hub so a failed drive unit is swapped inside a single shift rather than waiting on a container from Asia. Battery swap is not offered because the 600 kWh pack is structural, but the capacity is large enough that a second 360 kW charger covers three-shift operations without a swap station.
Drivers trained on diesel must relearn the TZ3V's instant torque and regen braking, especially on the loaded descent where lift-off recovers energy instead of coasting. Fenghan runs a two-day pit course covering one-pedal control, charge-window discipline, and emergency isolation, after which most operators prefer the electric truck for the cleaner cab and calmer ride.
Peruvian buyers land equipment at Callao or Matarani and move it over the cordillera on low-bed trailers. Fenghan manages export packing, marine insurance, and the mine-site commissioning including charger installation.
