Quick answer: At a typical commercial tariff of USD 0.10–0.14 per kWh, charging a Dongfeng electric truck costs USD 0.08–0.20 per km depending on duty cycle — about USD 0.09/km for a light box truck, USD 0.16/km for a 49 t tractor and USD 0.30/km for a loaded 6x4 mining dump truck. That is 55–75% below diesel on the same route.
Energy cost per kilometre is the single number that decides most fleet electrification business cases. Yet most published figures are passenger-car numbers scaled up, or manufacturer ideal values measured on a test track. This article uses measured kWh/km from our deployed export fleet, real commercial tariff structures, and a like-for-like diesel comparison so that a fleet CFO can put the figure straight into a model. It also covers the two costs that trip up first-time buyers — charging losses and demand charges — because ignoring either will make your post-audit numbers disagree with your business case.
Only two variables matter at the first level of accuracy. Everything else is a refinement:
Measured consumption across our range, taken from fleet telematics rather than type-approval data:
| Application | Representative model | Measured kWh/km | Cost/km at USD 0.12/kWh |
|---|---|---|---|
| Urban box delivery, 4.5–7.5 t | KT5M (262/310 kWh) | 0.55–0.75 | USD 0.07–0.09 |
| City delivery, 3.5–4.5 t | KT5J (262/310 kWh) | 0.48–0.65 | USD 0.06–0.08 |
| Regional rigid, 18–25 t | KTH3 (400 kWh) | 0.95–1.20 | USD 0.12–0.15 |
| Municipal sweeper / washing | KT1D / KT7A (232 kWh) | 0.60–0.85 (incl. body load) | USD 0.08–0.11 |
| Terminal tractor, port shuttle | TE46 (400 kWh) | 1.05–1.25 | USD 0.13–0.15 |
| Line-haul tractor, 49 t | TE8L electric tractor (400/466/600 kWh) | 1.25–1.40 | USD 0.15–0.17 |
| Heavy-haul tractor, 80–120 t | TE8M / TE8P (466–600 kWh) | 1.40–1.65 | USD 0.17–0.20 |
| 6x4 construction tipper | TZ5E / TZ3Z (400 kWh) | 1.50–1.90 | USD 0.18–0.23 |
| 6x4 mining dump, laden haul | TZ3V (600 kWh) | 1.90–2.40 | USD 0.23–0.29 |
| Concrete mixer, drum load | TZ8J (333 kWh) | 1.30–1.70 | USD 0.16–0.21 |
Take the most common export configuration — a 400 kWh pack:
Most fleets never run 0–100%. A 20–90% daily window on 400 kWh is 280 kWh usable, roughly 200 km, and costs USD 34–40 at standard commercial rates. The reason we recommend that window is not just battery life — it is turnaround time, because the last 10% of charge is the slowest part of the curve.
Here is the same corridor, same payload, both fuels at realistic 2026 prices:
In markets with subsidised electricity — much of the Gulf, hydro-backed grids in Central Asia, and industrial-zone tariffs in Southeast Asia — the saving widens. In markets with high commercial tariffs and heavy demand charges, it narrows, which is exactly why depot electrical design belongs in the business case and not in an appendix.
Almost every first electrification budget is wrong for the same two reasons:
Indicative commercial electricity prices our customers actually pay, which is what determines your number:
Where duty cycles are continuous — mining, port shuttle, 24-hour concrete — battery swap changes the cost model from energy-per-kWh to a per-swap or per-kWh service fee. A swap takes 5–6 minutes instead of 40, so the truck earns instead of waiting, but the swap provider prices in battery ownership, station capex and spare packs. Our rule of thumb: swap wins above roughly 18 operating hours per day or where charger capex at the depot is prohibitive; plug-in charging wins below that. The full trade-off is set out in charging vs battery swap fleet strategy, and swap economics for a specific truck are worked through in our Chile market page.
Three steps, in this order:
Do that and the answer to "how much does it cost to charge an EV truck" stops being a marketing claim and becomes a line item your finance team will sign off.
At a typical commercial tariff of USD 0.10–0.14 per kWh, charging a Dongfeng electric truck costs USD 0.08–0.20 per km depending on duty cycle: about USD 0.08–0.10/km for a light box truck, USD 0.15–0.20/km for a 49 t tractor and USD 0.28–0.34/km for a loaded 6x4 mining dump truck.
Yes, typically 55–75% cheaper per km. A diesel tractor burning 32 L/100 km at USD 1.05/L costs about USD 0.34/km; the equivalent electric tractor at 1.35 kWh/km and USD 0.12/kWh costs about USD 0.16/km including charging losses.
Measured consumption: 0.55–0.75 kWh/km for light box trucks in city duty, 1.0–1.2 kWh/km for 18–25 t rigids, 1.25–1.45 kWh/km for 49–80 t tractors, and 1.6–2.4 kWh/km for loaded 6x4 dump trucks on haul roads.
Yes, materially. Demand charges billed on peak kW can add USD 0.03–0.06 per kWh if a fleet charges simultaneously; shifting to night windows and staggering charger starts usually recovers most of that, and smart load management does it automatically.
About USD 48–56 for a 0–100% charge at USD 0.12–0.14 per kWh including roughly 8% charging losses, giving 250–300 km of range. Most fleets charge 20–90% daily, which costs USD 38–45.
