KTH3 Electric Cargo Truck Fleet Operations: Route Planning, Load Factor and Utilisation Tracking

The Dongfeng KTH3 electric cargo truck — CATL 400 kWh LFP, LvKong 450 kW (612 hp) — is the heaviest rigid in our range, and it is bought for regional work where distance, payload and terrain all vary. That variability is what makes fleet operations the deciding factor in whether it performs. Two operators running identical KTH3 units on similar corridors can report cost per tonne-kilometre figures 15% apart, and the difference is almost entirely route planning, load factor and driver behaviour. This article sets out the operating discipline.

Plan Routes in Energy, Not Distance

The most important change an operator makes when electrifying is to stop planning in kilometres:

The operational consequence: a 300 km route is not a single planning category. It must be decomposed into segments, each with its own consumption figure, and the sum determines whether the vehicle completes the day on one charge.

Load Factor: The Metric Most Fleets Ignore

Load factor — the share of available payload actually carried — drives cost per tonne-kilometre more than any vehicle specification decision:

• A KTH3 running at 55% load factor delivers 55% of the useful work for roughly 90% of the energy, because a lightly loaded truck still carries its own tare and still overcomes rolling resistance.
• Raising load factor from 55% to 80% improves cost per tonne-kilometre by roughly 30% — a far larger effect than any efficiency measure on the vehicle itself.
• Electrification does not change this, but telematics makes it visible. Fleets that start measuring load factor usually find 10–20 points of headroom in their existing network.

Payload measurement is covered in weigh-in-motion and payload telematics.

Utilisation Metrics to Track Weekly

1. kWh/km by route — the primary efficiency measure; investigate anything more than 5% above plan.
2. Load factor by route — weight and cube utilisation tracked separately, because they fail differently.
3. Energy per tonne-kilometre — the metric that combines both and that finance understands.
4. Availability — planned operating hours minus downtime, divided by planned hours. Target above 95%.
5. Charge session success rate — target 98% or better; below that, the problem is usually connector wear or scheduling, not the vehicle.
6. Arrival state of charge — enforce a minimum of 15% at end of leg.

Data structure and reporting are covered in fleet telemetry and driver behaviour analytics.

Charging Scheduling for a Regional Rigid Fleet

Regional KTH3 duty typically runs 200–350 km per day, so the energy plan is:

• Daily energy: 190–380 kWh depending on load and terrain.
• Overnight window: 8–10 hours. A 44 kW AC bay replaces roughly 350–440 kWh overnight at 90% efficiency — sufficient for most single-shift duty.
• Shared DC: one 120–180 kW unit per 3–4 trucks where a second partial shift or an unplanned redeployment is likely.
• Opportunity charging at a cross-dock: where routes are split into two legs with a hub in between, a 30–40 minute charge at the hub removes the range constraint entirely.
• Load management: mandatory above roughly five vehicles on one site to control demand charges. See smart charging load management.

Driver Coaching: Where 5–10% Sits

Three behaviours produce most of the driver-driven variance:

• Anticipation and regeneration. Lifting early into junctions, roundabouts and downhill sections recovers energy that late braking wastes. On regional routes with frequent speed changes this is worth 5–9%.
• Speed discipline. Consumption rises roughly with the square of speed above about 70 km/h. Holding 80 instead of 90 km/h on a highway leg is a measurable saving.
• Auxiliary discipline. Pre-condition the cab while still plugged in rather than on pack energy, and avoid leaving HVAC at maximum with doors open during loading.

The training curriculum is set out in our driver training programme, and incentive design in driver incentive scheme design.

Maintain the Conditions That Preserve Efficiency

Four maintenance items have direct energy consequences, which is unusual and worth stating:

1. Tyre pressure. Under-inflated tyres raise rolling resistance measurably; a 10% pressure shortfall costs several percent in consumption.
2. Wheel alignment. Misalignment increases consumption and tyre wear simultaneously.
3. Cooling circuit condition. A degraded thermal system forces the pack to operate outside its preferred window, which raises consumption and accelerates degradation. See coolant service.
4. Brake drag. A binding brake consumes energy continuously and is easily missed without telematics.

Southern African Regional Freight

Southern African regional corridors combine long distances, variable road quality, altitude and hot conditions — the combination where segment-by-segment energy planning matters most, and where the KTH3's 400 kWh pack and 450 kW motor earn their specification. Our South Africa market page covers deployment, import and support for South African fleets. Related: Durban port fleet, mining fleet electrification and Southern Africa import guide.

90-Day Operating Plan

• Weeks 1–2: instrument baseline routes; establish kWh/km and load factor per route.
• Weeks 3–4: driver coaching on anticipation, speed and auxiliaries.
• Weeks 5–8: revise routing and load consolidation using measured data.
• Weeks 9–12: review charging schedule against actual energy; then scale the fleet.

KTH3 FOB pricing typically falls in the USD 78,000–115,000 band depending on body and specification, with the CATL pack warranted 8 years / 4,500 cycles to 80% state of health.

Network Design: The Lever Bigger Than the Vehicle

Operators often expect electrification to change their network. In most cases it should not — but measuring the network properly almost always reveals savings that exceed the vehicle change itself.

• Consolidate low-density routes. A route running at 45% load factor costs nearly as much energy as one at 80%. Consolidating two thin routes into one full one is the single largest available saving in most regional networks.
• Re-examine the depot-to-first-drop leg. Deadhead mileage at the start and end of a shift carries no payload and consumes energy. Where a satellite parking location exists, it may be worth more than additional battery capacity.
• Sequence drops by mass, not just geography. Delivering the heaviest drops first reduces the energy consumed while the vehicle is at its heaviest, and improves regenerative recovery on the lighter remainder of the round.
• Review the return leg. Empty returns are often unavoidable, but where a backhaul exists it converts a pure cost into revenue at marginal additional energy.

Each of these is measurable, and telematics makes the measurement routine rather than a one-off study. Fleets that run this exercise before their second order typically find 8–15% of network cost that has nothing to do with the vehicle specification — which is why we recommend doing it early rather than treating electrification as a purely technical project.
