Can Electric Trucks Complete Your Routes? Payload, Range, and Charging

Electric trucks can complete a route reliably when three conditions align: the vehicle carries the required load legally, its available battery energy covers the duty cycle with a workable reserve, and charging fits the time between assignments. Advertised range alone cannot establish any of these conditions.

A predictable depot-return route is often a strong starting point, but distance is only part of the assessment. A short route with heavy auxiliary demand or a tight turnaround can be harder to electrify than a longer route with moderate loads and an overnight charging window. Evaluate the complete working day, including loading, waiting, repositioning, and the next departure.

Define the assignment before comparing electric trucks

Start with dispatch records and vehicle operating data. Daily mileage averages hide the demanding days that determine whether a truck can stay on its assigned work. Separate regular duties from exceptional trips, then establish which the proposed vehicle must cover without reassignment.

Build a route profile that includes:

• Distance by road segment, operating speed, elevation changes, and stop frequency.
• Departure times, return times, loading periods, and actual parking windows.
• Payload at departure and how it changes through deliveries or collections.
• Body, trailer, refrigeration, lifting equipment, and other powered accessories.
• Seasonal temperatures, congestion, diversions, and recurring delays.

Keep tractor and trailer configurations specific. A consumption estimate for one trailer height, body type, or gross combination mass may not transfer well to another. For collection work, model the increasing load toward the end of the route. For multidrop deliveries, account for the heavier outbound leg and lighter return.

Define success in operational terms before requesting proposals: required cargo, delivery windows, minimum return charge, and acceptable charging stops. This gives suppliers a common assignment to assess and makes their answers comparable.

Check payload and axle loads before battery size

A truck that completes the distance but cannot carry the required freight is unsuitable for that assignment. Battery weight affects available payload, but the outcome depends on the complete vehicle specification and the weight limits applying to its operating territory.

Compare vehicles in ready-to-work condition. Include the body, coupling equipment, driver, tools, refrigeration equipment, tail lift, and other permanent fittings. For articulated combinations, assess the tractor and trailer together. A chassis weight without the intended body or equipment is an incomplete basis for a purchasing decision.

Usable payload is constrained by both total permitted weight and individual axle loads. A vehicle can remain below its gross weight limit while overloading an axle. Battery placement, wheelbase, body length, fifth-wheel position, and cargo distribution all affect the result.

Assess axle loading at representative stages of the route, especially where partial unloading changes weight distribution. Also check coupling loads, axle-group limits, and the practical freedom to reposition freight. Any additional weight allowance for electric vehicles must be assessed for the relevant country, route, and configuration; it should never be assumed to create an equal increase in usable cargo capacity.

For volume-limited freight, battery mass may have little effect on shipment count. For dense bulk materials, liquids, or heavily loaded general freight, a payload reduction can require extra trips. That changes energy use, driver hours, and cost per delivered tonne, even if the electric vehicle’s individual route appears feasible.

Build an energy budget for the loaded duty cycle

Use available battery energy rather than nominal battery capacity. The relevant quantity is the energy accessible within the planned operating window, after accounting for battery-management limits, the chosen departure charge, and the required return reserve. Establish how those values change under the temperatures and battery condition being assessed.

A useful calculation is:

Route energy requirement = driving energy + auxiliary energy + contingency allowance.

Driving energy should reflect load, speed, gradients, traffic, and weather. Auxiliary energy includes equipment supplied by the vehicle battery, such as cab climate control, refrigeration, pumps, or an electric power take-off. If refrigeration uses a separate energy source, keep that demand separate while retaining it in the overall operating-cost assessment.

Use clear measurement boundaries. Battery energy consumed during the route and electricity purchased at the meter are different quantities. Charging losses matter for electricity cost and site capacity, but should not be added again to a route-consumption figure that already measures battery discharge.

A supplier’s consumption estimate is useful when its assumptions match the assignment. Ask which payload, body, speed profile, ambient conditions, and auxiliary loads underpin it. A single energy-per-distance figure can support initial screening, but route segments provide a better model where operating conditions change substantially.

Terrain, temperature, and speed change the result

Highway work exposes the truck to sustained aerodynamic demand. Lower-speed distribution reduces that demand but introduces repeated acceleration and longer periods running auxiliaries. Regenerative braking can recover some energy during deceleration and descents, although it cannot recover all the energy previously used.

Route direction matters on hills. A loaded climb followed by an unloaded descent produces a different energy balance from the reverse assignment. Regeneration may also be restricted when the battery is near its upper charge limit or outside favorable operating temperatures. A descent therefore cannot automatically be treated as fully available energy recovery.

Cold conditions can increase heating demand and affect battery performance and charging. Hot conditions add cooling demand. For refrigerated transport, include cargo temperature requirements, door-opening frequency, and stationary operating time. Energy use can continue while the vehicle makes no progress along the route.

Allow for variation and battery aging

The reserve should cover defined disruptions: a diversion, a delayed unloading slot, extra auxiliary use, or an unavailable charger. An unexplained margin offers little insight into which risks the route can tolerate.

Assess the assignment at both initial battery condition and a realistic later-life condition. Capacity loss reduces the energy available between charges, while battery condition and temperature can also affect charging performance. A route that only works with a new battery and favorable weather has limited operational flexibility.

Run a normal operating scenario and a demanding but credible scenario. Use combinations that can actually occur together, such as heavy cargo and winter heating, rather than stacking unrelated worst cases into an implausible calculation.

Match charging to dispatch windows

Charging feasibility depends on energy delivered before departure, not the charger’s headline power rating. Actual power is limited by the truck, charger, battery state of charge, battery temperature, and available site capacity. Power commonly changes during the session, so dividing required energy by peak charger output can underestimate charging time.

Distinguish parked time from connected time. A truck may spend hours at the depot while moving between unloading, washing, inspection, and parking. Those activities can shorten the usable charging window or require a different yard layout.

For depot charging, model the fleet’s arrival and departure sequence. Several vehicles returning together can create a power peak. Managed charging may distribute demand across the night, provided every vehicle still receives its required energy before departure. Available connection capacity, other site loads, charger installation, and vehicle rollout schedules must align.

Public or shared charging needs an access assessment as well as an electrical one. Check connector compatibility, vehicle voltage compatibility, cable reach, bay dimensions, trailer clearance, opening hours, and payment arrangements. A charger that a passenger car can use may be inaccessible to a tractor-trailer combination.

Then test disruption recovery. If a charger fails or a truck returns late, can another unit deliver enough energy in the remaining window? An alternative charger only provides useful backup when the truck can reach it, connect, and still meet its assignment.

Choose battery capacity around the working day

The largest battery is not automatically the best specification. Additional capacity can improve route flexibility and reduce dependence on intermediate charging, but it can also increase vehicle mass and purchase cost. Where cargo weight limits revenue, that trade-off deserves explicit calculation.

A smaller battery may suit repeatable routes with dependable charging between assignments. It becomes less attractive when small scheduling changes force an extra stop or leave dispatch dependent on a single charger.

Compare complete operating plans: one vehicle with enough energy for the shift, another using a planned charging opportunity, and a mixed fleet assigning electric trucks to suitable duties. Include payload, charger investment, electricity charges, driver time, maintenance support, and replacement-vehicle arrangements. Compare cost per completed delivery, tonne, or route according to the work performed.

Also check service readiness. Workshop access, diagnostic support, parts availability, recovery procedures, and body-equipment integration affect whether a technically capable truck remains available for work. For specialized bodies, establish who supports faults involving both chassis and auxiliary systems.

Use the trial to test the operating boundaries

A useful fleet trial answers specific unresolved questions. Run the intended body and trailer, representative cargo, normal drivers, and actual charging arrangements. Record payload, route completion, departure and return charge, battery energy consumption, charging duration, and schedule deviations alongside temperature and traffic conditions.

Include demanding regular assignments. If seasonal conditions cannot be reproduced during the trial, retain them as a separate modeled acceptance case. A successful mild-weather run does not resolve winter feasibility.

Set acceptance criteria before collecting results. The truck should carry the required freight within applicable limits, complete the agreed duties with its specified reserve, and regain enough charge for the next assignment. Record any operational intervention, including load transfers, route changes, charging queues, and vehicle substitutions. These reveal dependencies that a simple completed-trip count can hide.

The purchasing decision should identify which routes the configuration can cover, under what conditions, and with what charging support. Begin with a route where load, energy demand, and parking time are well understood, then expand as operating data supports the next assignment.
