Dongfeng KTH Electric Cargo Chassis Guide: KTH1, KTH2 and KTH3

What is listed for KTH1, KTH2 and KTH3

The project catalogue identifies KTH1 as an 8x4 cargo chassis in the 31 t GVW class. Its listed configuration includes 264 kWh, 270 kW rated / 450 kW peak motor output, a four-speed e-axle, 1,850 + 3,650 + 1,350 mm wheelbase, DF451S / DF400 axle entries, 11R22.5 tyres, EBS and GB charging with a 120 kW body interface. KTH2 and KTH3 are grouped in a family row: 8x4, 31 t class, 352 / 400 kWh, up to 450 kW, electric drive and application-matched series configuration. The row notes that KTH3 supports a 9.8 m body.

The grouped KTH2/KTH3 row is deliberately less specific than the KTH1 row. It does not state a model-by-model battery assignment, exact wheelbase, axle set, tyre, charge inlet or safety package. Do not transfer KTH1 details to KTH2 or KTH3, or assume every listed option is available together. Ask for a signed technical schedule bearing the exact model code and destination-market version.

GVW means gross vehicle weight, not payload. The 31 t class cannot be used as a statement of material or cargo carried. The completed chassis, body, equipment, occupants, axle loads and local approval determine the allowable payload. Ask the supplier for completed mass and axle distribution for the proposed body before doing a route or revenue calculation.

Match the chassis to the transport assignment

Define the work before choosing a family member: cargo type, mass and volume, loading method, shift distance, route grade, road quality, stops, delivery windows and depot return. A high-capacity body for low-density goods has different packaging needs from a compact body carrying dense products. Repeated urban drops prioritize access, turning and driver workflow; regional work may emphasize payload, route energy, charging opportunity and service coverage. These are operating questions, not assumptions about a model's unlisted performance.

For each candidate, compare the completed body dimensions with loading docks, warehouse doors, bridges, turning areas and parking bays. Consider overall length, wheelbase, rear overhang, roof height and the space needed for tail lifts, refrigeration equipment or side access. The KTH3 9.8 m body note is a catalogue capability note, not confirmation that every body of that length will fit every chassis, route or legal envelope. Obtain approved drawings from the body builder and vehicle supplier.

Use actual load records to understand whether gross mass, axle distribution, volume or loading time is the limiting factor. For each shift collect dispatch and return times, distance, stops, weights, energy, weather and charging events. Where the fleet does not yet have electric-vehicle records, use a carefully controlled pilot or a supplier-supported duty assessment. Do not infer range from battery capacity alone.

For more developed 4x2 urban delivery platforms, compare the separate KT5M / KT5J cargo-truck guide. The battery capacity guide explains how to compare pack sizes using shift energy and reserve, while the cargo range page lists the current catalogue family entries.

Design the body and chassis as one system

Specify the body type, internal dimensions, floor, side structure, doors, loading equipment, tail lift and any temperature-control system. Confirm body mass both empty and with installed equipment. Refrigeration, lift gates, cranes, tool storage, guards and auxiliary batteries all change completed mass and may affect axle loading. Ask for loading and unloading cycle time too; a truck that has sufficient nominal battery capacity can still miss a route window if dwell and equipment operation are not planned.

Request chassis frame drawings, mounting locations, permissible body mass, center-of-gravity constraints and the approved electrical interfaces. Confirm who supplies power take-off or body power, wiring protection, isolation, controls, safety interlocks and commissioning. The KTH1 data specifically lists a 120 kW body interface, but buyers still need to clarify output characteristics, duty limitations, connector and integration scope for the selected configuration. Do not assume this interface is equivalent to any third-party body system without engineering confirmation.

Get the supplier and body builder to agree interface ownership in writing. The deliverables should include drawings, interface control information, completed mass calculation, axle-load statement, installation method, inspection access and commissioning records. Clarify who troubleshoots a body-side fault and whether it affects vehicle warranty or service responsibility. For export orders, obtain documents and manuals for the actual body as well as the chassis.

Plan safe access to high-voltage components and body equipment during maintenance. The body should not obstruct charging ports, service panels, cooling airflow, camera views or routine inspection points. Confirm the placement of charging inlet, emergency cut-offs and body controls on the actual build. This coordination is easier before production than after a body is already mounted.

Size the battery using a representative shift

KTH1's listed 264 kWh and the family row's 352 / 400 kWh values do not by themselves predict a route distance. Energy depends on payload, speed, grade, stop frequency, weather, cab climate and any body loads. A refrigerated body, lift gate or other powered equipment may introduce auxiliary consumption, but the amount must be measured or supported by the supplier for the specific equipment. Keep traction and body energy assumptions distinct where possible.

Build a shift profile from loaded and empty legs, start/return state of charge, operating hours, dwell, traffic and charging access. Include a reserve for detours and charger interruption. Follow the approved operating guidance for the exact vehicle rather than assuming nominal battery capacity is entirely available for routine work. For a multi-shift operation, map charging windows against driver schedules and vehicle turnaround; do not count theoretical dwell unless a charger is available and the truck can remain connected.

Plan charging, maintenance and fleet support

For KTH1, the catalogue notes GB charging; the family row gives configuration-dependent market matching. Verify the exact inlet, connector, communication protocol, charger output accepted by the vehicle and any limits for the target country. A label in a family brochure does not establish compatibility with a particular charging station. Arrange a joint acceptance test with the vehicle and charger suppliers and define what happens if charging fails.

Review electrical supply, load management, parking layout, cable reach, protection and emergency access with qualified professionals. Schedule vehicles around actual departure times and simultaneous charging demand. If the body uses a high-power interface, coordinate body operations and charging so the combined site load and workflow are understood. The KTH1 entry's 120 kW note should not be treated as charger capacity or as a verified body-system output without the detailed technical definition.

Before fleet handover, agree routine inspection, diagnostics, parts availability, service response, body-builder support and driver training. For a heavy 8x4 cargo chassis, recovery, tyre replacement and access to maintenance facilities can determine availability. Confirm vehicle and body responsibilities, warranty terms and exclusions in the commercial documents; do not assume support scope from a model name.

What is not established by the catalogue

The available data does not establish range, payload, charge duration, price, warranty, production availability, body approval or destination-market certification for KTH variants. The KTH2/KTH3 family row is particularly incomplete for exact model-level configuration. It also does not specify a complete body design. Do not fill these gaps by copying KTH1 values to its siblings or extrapolating from battery capacity.

Request the exact model code, final battery and motor, wheelbase, axles, tyres, safety systems, connector, completed mass, body drawings, permissible loads and service scope in a current technical offer. If any field is pending engineering or market confirmation, ask the supplier to identify who will resolve it and when. This keeps the comparison usable for procurement without presenting an incomplete family summary as a final build commitment.
