A mobile clinic must do two jobs at once: drive to where patients are, and then sit still running refrigerators, lights, computers and diagnostic kit without the noise and fumes of a idling diesel. The SAGMOTO i5 electric light-medium truck is a natural base for a mobile health unit because its permanent-magnet drive develops 120 to 160 kW, its 100 to 140 kWh pack gives around 200 km of range, and when it stops it draws medical power from the battery with no engine running at all. This guide explains the electrical supply for medical equipment, climate control, interior fit-out, the silent-operation benefit, range planning for rural outreach, and charging strategies where the grid is weak.
1. Electrical Supply for Medical Equipment
The i5 high-voltage battery feeds a 220 V or 110 V inverter rated to the clinic load, which typically runs a vaccine refrigerator at 300 to 600 W, LED lighting at 200 W, a laptop and printer at 150 W, an ultrasound or exam device at 400 to 800 W, and an air-conditioning unit at 1,200 to 2,500 W when running. A realistic clinic draws 2.5 to 5 kW sustained while parked, and the 100 to 140 kWh pack covers a full clinic day of six to eight hours with margin before the drive home. We fit a dual inverter with a transfer switch so a fault on one leg does not drop the cold chain.
The medical circuit is isolated from the drive circuit and protected by its own RCD, because a patient-area shock path is unacceptable. We also add a battery monitor that warns the crew at 30 percent pack so the refrigerator is never at risk of losing cooling mid-session.
2. Climate Control for Patient Comfort
A clinic must hold a steady cabin temperature for both patient comfort and vaccine storage, and the i5 runs its cab and box climate from the pack through a dedicated electric heat pump. For hot regions we specify a 2.5 to 4 kW rooftop heat pump with a back-up resistive heater for cold snaps, drawing from the main pack rather than a separate engine. Because there is no diesel heater exhaust, the box air stays clean, which matters for respiratory patients and for the cold-chain integrity of the drugs on board.
We insulate the box to a high R-value so the heat pump cycles gently instead of fighting heat gain all day, which protects both the pack range and the compressor life across a multi-stop outreach week.
Protect the cold chain first: Size the pack and the refrigerator so the vaccine compartment holds temperature even if the clinic runs two hours longer than planned. A dead refrigerator is a failed mission and a lost batch, so the cooling load is the priority circuit on the i5 clinic build.
3. Interior Fit-Out and Layout
The i5 box is laid out as a clean workflow: a entry step and handwash station at the rear, a consult desk along one wall, the vaccine refrigerator and a lockable drug cabinet on the other, and an exam couch or chair at the front near the cab bulkhead. We specify a sealed floor, wipe-clean wall panels and a non-slip step, because a clinic must meet basic infection-control expectations to be accepted by a health authority. The layout is drawn to the door swing and the corridor width so two people can work the box without blocking the patient path.
Storage is built to the outreach list: vaccines, consumables, records and a sharps bin each get a fixed home, and the cab carries the driver's records tablet. We pre-wire the box for a satellite or mobile internet router so the records sync at the end of the stop.
Medical gas and oxygen need their own secure bracket and a vented cabinet, because a loose cylinder in a moving box is a hazard and a leak in a sealed clinic risks the patients and the staff. We fit the oxygen holder to the wall away from the heat pump intake and route the regulator through a fixed point so the clinician connects a single line at the consult. The sharps and waste bins are foot-operated and locked for transport, meeting the basic standard a health authority expects before the unit is licensed to see patients on a village stop.
4. Silent Operation Benefit
The single biggest quality gain of an electric clinic is silence. A diesel clinic idles through the whole session, filling the box with noise and exhaust that patients, especially children, find stressful, and that the clinician must talk over. The i5 sits dead quiet on its pack, so the consult is calm, the equipment fans are the only sound, and the unit can park outside a school or a clinic without the noise complaint a diesel draws. In wildlife or remote settlements the quiet arrival is also a community-relations win.
Silence also helps the equipment. With no engine vibration through the floor, the ultrasound and the refrigerator mounts last longer, and the clinician's concentration through a long day is measurably better than in a rattling diesel box.
5. Range Planning for Rural Outreach
The i5 100 to 140 kWh pack delivers around 200 km of mixed range, but a clinic route is not highway miles: it is short hops between villages with the box running, which uses pack for both drive and medical load. We plan a rural loop at 120 to 160 km of actual travel plus six to eight hours of clinic draw, and we keep a 20 percent reserve for the drive home and for a longer stop than expected. For a 140 kWh pack that is comfortable; for a 100 kWh pack the loop is tighter and we trim the equipment hours or add a midday top-up.
The terrain sets the buffer. Hilly villages eat more drive energy, so we model the route profile and derate the range by 15 to 25 percent for climbs, then brief the driver to recharge rather than risk the reserve on a remote grade with no charger at the far end.
| Pack size | Drive range | Clinic hours | Best loop |
|---|---|---|---|
| 100 kWh | About 160 km | 5 to 6 h | Dense near-town |
| 120 kWh | About 185 km | 6 to 7 h | Suburban outreach |
| 140 kWh | About 210 km | 7 to 8 h | Rural multi-village |
6. Charging Strategies in Weak-Grid Areas
Many outreach destinations have a grid that is unreliable or low-capacity, so the i5 clinic plan includes charging that does not depend on a perfect socket. At the depot we fit a 40 to 60 kW DC charger that fills the pack overnight or in two hours; at village stops we use a 7 to 11 kW AC wallbox where the local supply holds, and we brief the crew to charge during the clinic session so the pack is full for the drive home. Where the grid sags, we add a voltage stabiliser so the charger does not trip and the cold chain stays safe.
For truly off-grid stops we pair the i5 with a solar or a small generator top-up, but the preference is always grid or depot charging because it is cheaper and cleaner. The vehicle-to-load port can also feed a small building if the clinic runs longer than the pack allows, which turns the truck into a temporary power source for the health post.
A simple depot routine protects the pack over years: arrive, plug to the 40 to 60 kW charger, run the clinic, and leave with the pack above 80 percent so the next morning starts cold and full. We log each charge in the vehicle tablet so the operator can see the pack health trend and catch a cell that ages early, which is the difference between a clinic that runs five days a week and one stranded by a surprise range drop on a remote road. The discipline costs nothing but keeps the unit available where the nearest charger may be a hundred kilometres away.
Charge while you clinic: Plug the i5 into the village wallbox the moment you arrive, because a six-hour session on a 7 kW supply returns most of the day's draw while the crew works. Leaving charging to the end of the day risks a low pack and a nervous drive home on a dark road.
7. Driver and Crew Training
An electric clinic drives like any i5 but the crew must learn the power budget. We train the driver to watch pack percentage against the route, to plug in at every stop with supply, and to lift off early for regen on the village descents. The clinician learns the inverter transfer switch and the cold-chain alarm, and the whole team runs a one-page start card: plug in, set the heat pump, check the refrigerator, brief the queue. A ten-minute routine at the first stop prevents the failures that waste a outreach day.
| Item | Daily check | Why |
|---|---|---|
| Pack percentage | Before roll-out | Range reserve |
| Refrigerator temp | Per stop | Cold chain |
| Inverter switch | On arrival | Medical power |
| Charger lead | Every stop | Top-up |
| Heat pump | Per climate | Patient comfort |
Conclusion
The SAGMOTO i5 electric truck makes a quietly effective mobile clinic because its 120 to 160 kW drive and 100 to 140 kWh pack carry a health unit about 200 km and then run the refrigerator, lights and diagnostics in silence with no idling diesel. Protect the cold chain with an isolated dual inverter, insulate the box for a gentle heat pump cycle, plan the rural loop with a 20 percent reserve, and charge at every stop with supply.
