The Bushveld Complex around Rustenburg holds the bulk of the world’s platinum-group metals, and its open-pit and underground-adjacent haulage is a high-tonnage, fixed-route duty that is ideally suited to the electric truck. For South African mining houses fighting load-shedding and diesel exposure, the Dongfeng TZ5Y 80t-class electric mining truck — with a 5–6 minute battery swap and solar buffering — turns a reliability problem into a resilience advantage. This article covers the TZ5Y, the swap model, the Bushveld TCO, and a deployment path for platinum producers. The swap model in particular turns a national-grid weakness into a mine-controlled strength.
Mining haulage is continuous: a truck that sits 45 minutes on a charger is a truck not moving rock. The TZ5Y solves this with battery swap in 5–6 minutes — comparable to a diesel refuel — so the truck stays on the haul road. At a Bushveld pit, a swap station with a few spare packs keeps a fleet of TZ5Y units running 20+ hours/day with no charging downtime. This is the decisive difference between a passenger-derived electric truck and a purpose-built mining EV truck. Because the swap decouples energy refill from the truck, the pit can charge packs on its own solar schedule and the haulage never waits for a charger.
The TZ3V 8x4 electric mining dump truck platform shares the heavy-electric architecture that the 80t-class TZ5Y builds on, giving mining buyers a proven powertrain baseline.
| Parameter | TZ5Y Specification |
|---|---|
| Payload class | 80 t class |
| Battery | CATL LFP, 560 – 600 kWh (swap pack) |
| Drive motor | LvKong permanent-magnet, 450 – 510 kW |
| Battery swap time | 5 – 6 minutes |
| DC fast charge (20–80%) | 45 – 60 min (backup) |
| Battery warranty | 8 years / 4,500 cycles to 70% SOH |
| FOB price (China) | US$150,000 – 180,000 |
The 560–600 kWh swap pack is sized for a full pit shift between swaps; the 450–510 kW motor holds grade on the loaded haul road out of the pit. LFP chemistry tolerates the deep, frequent discharge cycles mining demands, and the sealed, mine-grade enclosure keeps dust and water out of the high-voltage system.
South African mines pair a swap station with a 200–500 kWp solar array and container storage. Packs charge from solar during the day and from grid/off-grid at night; when Eskom load-sheds, the mine keeps hauling because the swap packs are already buffered. The truck pack itself becomes part of the site microgrid — stored energy that would otherwise be curtailed. This is the single biggest reason platinum houses choose swap over charge: the haulage line stops being a victim of the national schedule.
An 80t diesel hauler burns ~55 l/hour over ~5,000 hours/year — 275,000 l. South African diesel at ~US$1.10/l is ~US$302,500. The TZ5Y at ~2.2 kWh/tonne-km equivalent draws ~1.2 GWh; at solar-buffered US$0.09/kWh that is US$108,000. Energy saving ~US$194,500/year, plus ~US$40,000 maintenance (no engine overhaul, regen brakes, fewer fluids) — ~US$234,500 annual advantage per truck. Against the FOB step from a diesel 80t unit, payback lands inside 24–36 months at pit scale, and the load-shedding uptime value is additional. A pit running two shifts reaches payback fastest.
The rollout is a pilot of three TZ5Y units plus one swap station on a single pit–crusher lane for 120 days, with tonne-moved and kWh/tonne telemetry, then a scaled order. Build the swap station and solar first — that capex gates the trial, not the trucks. Once the lane proves out, replicate across pits; the spare-pack pool scales with the fleet.
Place the swap station at the crusher, not the pit, so the empty return leg carries the depleted pack in and the full pack out — the truck never detours. Train a two-person swap crew per shift; the 5–6 minute swap is a crane-and-latch routine, not a repair, so pit crews pick it up in a day. Hold the spare packs on a slow-charge rack fed from solar, and the station becomes the mine’s buffer store during load-shedding. Siting and training, not the truck, decide whether the swap model pays.
The South Africa electric truck market guide covers Durban/Port Elizabeth clearing, NRCS homologation, and pit-side charging/swap layout. For Bushveld platinum houses, the TZ5Y is the EV truck that converts a diesel and load-shedding liability into a solar-resilient, low-cost haulage line.

One TZ5Y on a 30 km pit–crusher loop, 20 hours/day, 330 days a year, moves roughly 530,000 tonnes and draws ~1.2 GWh. At solar-buffered US$0.09/kWh that is US$108,000; the diesel equivalent at US$1.10/l and 275,000 l burns US$302,500 — a US$194,500 annual energy gap before maintenance. Add ~US$40,000 maintenance avoidance and the unit returns ~US$234,500/year against a US$165,000 FOB step, payback ~22–28 months. The swap station capex is the only gating item, and it amortises across the fleet, not the unit.
Load-shedding is where the number understates the value. A diesel hauler keeps running during an outage only if the mine has diesel for the generators; the TZ5Y keeps running because its swapped packs were charged from solar earlier in the day. The avoided downtime — tonnes not moved during a blackout — is often worth more than the fuel saving, and it is the reason platinum houses specify swap rather than charge.
Safety is the third return. Underground-adjacent headings with zero diesel exhaust remove a whole class of health and ventilation cost, and the quiet electric drive reduces fatigue on the long pit return. Mines that price the ventilation and incident saving find the EV truck pays back faster than the energy maths alone suggests.
Spares follow the mining norm: hold a spare pack, a spare motor and a spare inverter at the workshop. A 5–6 minute swap covers a pack fault; the other two cover a rare powertrain fault. With that pool, a 10-truck fleet runs at >95% availability — higher than the diesel fleet it replaced, because there is no engine to overhaul.
Carbon and ESG reporting now reaches into mining scope 1; an electric haul fleet with site solar scores near-zero on the haulage line, which supports both the licence to operate and the green-premium on refined metal. The EV truck is therefore a market-access tool, not only a cost tool.
