SAGMOTO i5 Electric Trucks for Hotel and Hospital Linen Logistics: Route and Payload Math

Linen logistics is a closed-loop urban duty cycle

Commercial laundry and linen supply is one of the most predictable transport tasks in the service economy. A laundry or linen rental plant receives soiled linens, washes, presses, folds and packs them, then returns clean stock to the same set of hotels, hospitals and care homes it collected from. The vehicle therefore runs a closed loop: it leaves the plant, drops clean cages and collects soiled cages at each stop, and returns to the same plant the same day. The customers are fixed, the order of the route is largely fixed, and the daily distance is bounded by the service area the plant can serve in a single shift.

That shape is close to ideal for a battery-electric light truck. The work is anchored to a single depot, the daily mileage is moderate, the vehicle spends much of its time in slow urban traffic and at loading bays, and the return-to-base pattern means the truck charges where the operator already controls the electricity. A diesel light truck in this duty spends a large share of its fuel on idling and short accelerations that an electric driveline recovers or avoids entirely, and it pays a noise and emissions penalty exactly where cities are tightening access rules.

The SAGMOTO i5 is configured for exactly this envelope. It is a battery-electric light truck built on a lithium iron phosphate pack of approximately 98 kWh, with a 131 kWh extended-range variant available for longer or more heavily loaded loops. LFP chemistry suits a vehicle that charges every night and is worked every day for eight to ten years: it trades a little energy density for a longer cycle life, better thermal stability and a flat, predictable degradation curve under daily deep cycling. For linen logistics that reliability matters more than a few extra kilometres of nominal range.

Route math: how far a laundry loop actually travels

Before specifying a truck, fix the numbers that describe the work. A hotel and hospital linen loop is usually built around a morning collection of soiled stock and a same-day or next-day return of clean stock, with a midday or evening redistribution to properties that run out before the next scheduled drop. The table below sets out typical loop profiles and the energy the i5 will consume under each, using a standard insulated panel body and cage-loaded cargo.

Linen is a low-density, high-bulk commodity, which makes volumetric capacity the binding constraint long before payload weight becomes one. A standard hotel queen flat is roughly 0.5 to 0.9 kilograms when clean and folded, and a soiled bag is heavier with moisture but still light by freight standards. The vehicle is therefore almost always full by volume before it is full by weight, so the planning question is how many roll cages the body holds, not how many kilograms it can carry.

Payload, volume and the roll cage question

A linen roll cage, sometimes called a laundry trolley, is the unit of handling in this business. A typical cage measures about 1.2 metres long, 0.8 metres wide and 1.7 to 1.85 metres tall, giving a gross volume of roughly 1.6 to 1.8 cubic metres. Empty it weighs 50 to 90 kilograms; loaded with clean folded linen or soiled stock it carries 120 to 250 kilograms depending on the mix. A hospital linen loop moves more volume per stop than a hotel loop because hospitals generate both patient linens and theatre and ward textiles in large loose volumes.

The i5 chassis accommodates a box body of roughly 18 to 24 cubic metres on the standard wheelbase, which holds about 10 to 13 cages when loaded tight, or about 8 to 10 cages when left accessible for quick dock handling. The 131 kWh variant uses the same body envelope, so cage count does not change between batteries; the larger pack simply extends the loop length and the margin against a heavy or hilly day.

Segregation of clean and soiled stock is a compliance issue in healthcare, not a nicety. Hospitals increasingly require clean and soiled linen to be transported in separated compartments or in separated and bagged cages, and a multi-compartment body that keeps the two streams apart removes a recurring audit finding. The weight penalty of the extra bulkhead is small against the i5 payload budget, and the operational benefit is that a single vehicle can serve a hospital without cross-contamination concerns.

Silent night delivery: the real advantage

Hotels and hospitals generate demand at awkward hours. Hotel kitchens and laundries want clean stock delivered before breakfast turns the loading bay into a guest thoroughfare, and hospitals want replenishment that does not disturb wards. A near-silent electric truck makes a delivery window that a diesel unit is increasingly barred from: many city centres now restrict noisy early-morning freight, and a quiet vehicle at the dock preserves access that combustion trucks are losing.

The i5 produces little noise at low speed and none of the idling clatter of a diesel unit parked at a bay. For a hotel on a residential street this means a 05:00 delivery that neighbourhoods do not notice; for a hospital it means linen can be staged before the day shift peaks. Operators who exploit this window report fuller docks, shorter handling times and fewer conflicts with guest and patient movement, none of which appear on a fuel spreadsheet but all of which reduce labour cost at the customer site.

Charging window: schedule the truck around the plant

Linen logistics returns the vehicle to the same plant every day, so depot charging covers the duty without any public infrastructure. A 22 kW AC supply returns a 98 kWh pack from 20 percent to full in roughly 4.5 to 5.5 hours, which sits comfortably inside the overnight gap between the evening return and the pre-dawn departure. Where a plant runs a split shift with a midday return, a 40 to 60 kW DC top-up reduces the same charge to 1.5 to 2.5 hours and makes a lunchtime boost practical during the driver break.

The electrical connection is the critical path, not the charger. Ten i5 units at 22 kW each need a connected load of 220 kW, and most plants will require an upgraded supply, a distribution board and load-management software to stay inside their contracted capacity. Smart charging that staggers the fleet and shifts the bulk of the draw into the off-peak tariff band is the difference between an energy cost of about USD 0.06 per kilometre and one of about USD 0.14 per kilometre. Linen plants already run compressors, boilers and tunnel washers on large supplies, so the marginal addition is usually manageable with proper planning.

Total cost of ownership against a diesel light truck

An honest linen-loop business case compares acquisition, energy, maintenance and residual value. The table below sets out an indicative five-year comparison for a single-shift urban linen loop running about 45,000 kilometres per year over a 300-day operating calendar.

At 45,000 kilometres per year the i5 saves roughly USD 6,000 to USD 10,000 annually in energy and maintenance, closing the acquisition gap including charger and electrical works between year three and year four. The crossover is faster where diesel is expensive, where the loop is dense urban with heavy idling, and where the plant has access to an industrial off-peak tariff. It is slower on largely highway trunk loops and where electricity is priced at commercial rather than industrial rates.

The maintenance advantage is structural rather than marginal. An electric driveline has no engine oil, no fuel filters, no aftertreatment system, no clutch and no exhaust, and brake wear falls sharply because regenerative braking performs most of the deceleration. On a linen loop with 10 to 22 stops per shift, pad life is typically three to four times that of a diesel equivalent, workshop hours per vehicle drop materially, and there are fewer components that can strand a vehicle on a time-critical hospital run.

Conclusion

The case for the i5 in hotel and hospital linen logistics rests on a clean match between duty cycle and vehicle design. The work is bounded in distance, dense in stops and anchored to a plant the operator controls. A 98 kWh LFP pack delivers 120 to 185 kilometres of cage-loaded urban range with reserve, the 131 kWh variant extends that to about 300 kilometres for larger loops, and overnight AC charging returns the vehicle to full inside the off-peak window. Removing engine, clutch, aftertreatment and most brake wear from the maintenance picture produces a structural cost advantage, while the near-silent low-speed operation preserves early-morning delivery windows that diesel trucks are losing.

The right next step for a laundry or linen-rental operator is a route survey rather than a brochure comparison. Fix the stop count, the cage requirement, the loop distance and the depot electrical capacity, then model the i5 against the current diesel cost per kilometre with the correct charging plan applied. Operators building mixed electric fleets for both light urban loops and heavier trunk movements should also review the full SAGMOTO new energy electric trucks line-up, since a linen plant often needs light urban units alongside larger chassis for inter-depot trunking.
