Quick answer: The SAGMOTO i9 is better for most urban cold chain work: about 96 kWh of LFP capacity and a 430 km working range leave headroom for refrigeration alongside roughly 4,500 kg payload at 12,000 kg GVWR. The i5 suits shorter inner-city pharmacy routes.
Electric trucks are well suited to cold chain work: routes are predictable, distances are moderate, return-to-base operation solves charging, and stop-start duty — which is punishing for diesel — is where electric drivetrains are most efficient. The important question is not whether electric works, but which platform has sufficient energy to drive the vehicle and run the refrigeration unit. This guide answers that question specifically for the i5 and the i9.
Why Refrigeration Changes the Range Equation
A refrigeration unit is a continuous electrical load. Unlike motive load, which varies with speed and duty, a cold unit draws whenever the box needs cooling — and it needs cooling most on hot days with frequent door openings. This has three consequences for specification:
- Usable range falls materially. Plan for roughly 20-35 percent less usable range than the nominal unladen cycle figure once refrigeration is included.
- Duty cycle matters more than distance. A route with many door openings imposes far more cooling load than one of equal distance with few stops.
- Standby capability protects the driving range. Running the cold unit from mains while parked preserves battery energy for the road, and should be regarded as standard specification rather than an upgrade.
Platform Comparison
| Parameter | SAGMOTO i5 | SAGMOTO i9 (light distribution) | SAGMOTO i9 (heavy distribution) |
|---|---|---|---|
| Battery chemistry | LFP | LFP | LFP |
| Battery capacity | 98 kWh nominal, 88 kWh usable | Approx. 96 kWh | 246 kWh or 350 kWh options |
| Nominal urban range | Approx. 220 km | Approx. 430 km (CCBC working range) | 280-400 km depending on pack |
| Estimated range with refrigeration | Approx. 160-180 km | Approx. 280-340 km | Approx. 220-320 km |
| GVWR | Light distribution duty | Approx. 12,000 kg | 26,000 kg |
| Payload | Suited to dense city loads | Approx. 4,500 kg | 11-13 tonnes |
| DC fast charging | Up to 120 kW, about 35 minutes to 80 percent | 120 kW, 20-80 percent in about 65 minutes | 180-250 kW depending on pack |
| Peak motor power / torque | 185 kW, 1,100 Nm | 167 kW, 1,100 Nm | Variant dependent |
Read across the range row and the payload row together, because that combination is the decision. Chilled delivery generally carries light product by weight relative to volume, meaning even a compact vehicle reaches its volumetric limit before its weight limit — but electric drivetrains add mass, so the payload column deserves attention rather than assumption.
Which Platform Suits Which Type of Cold Route?
| Route Profile | Recommended Platform | Reasoning |
|---|---|---|
| Inner-city pharmacy, 25-40 drops, under 120 km | i5 | Smaller package, sufficient range, easier parking |
| Grocery home delivery, 150-200 km daily, many drops | i9 light distribution | Range headroom covers refrigeration load comfortably |
| Regional wholesale cold chain, 200-300 km | i9 with larger pack option | Higher capacity needed, plus opportunity charging plan |
| Frozen goods requiring very low temperature | i9 with specified heavy-duty unit | Cooling load is materially higher at frozen setpoints |
| High-volume ambient plus chilled mix | i9 with dual-zone body | Zoning permits mixed loads without compromising either product |
Which Charging Strategy Works Best for Cold Chain Fleets?
Cold chain electric fleets almost always charge at the depot, which is the easiest scenario to plan. Three elements determine the depot design:
- Energy requirement per vehicle per night: calculate from actual daily consumption plus refrigeration energy, then add margin rather than sizing to the average.
- Charging window: the available off-peak hours. A vehicle needing several hours of AC charging and parked for eight is comfortable; one needing eight and parked for six is not viable without DC provision.
- Electrical capacity: the dominant practical constraint. Depot supply upgrades frequently cost more than the vehicles' chargers, and must be assessed before ordering, not after.
| Charging Mode | Typical Power | Approximate Time | Use Case |
|---|---|---|---|
| AC slow, single-phase | 7 kW | Overnight | Small vehicles with long dwell windows |
| AC three-phase | 22 kW | Around 3.5-5.5 hours | Preferred overnight mode for most fleets |
| DC fast | 60-120 kW | around 35-70 minutes | Opportunity top-up between routes |
| Mains standby for refrigeration | Grid connection | Overnight | Protects driving range; specify as standard |
How Do You Keep Cold Chain Audit Compliance?
Electric cold chain does not change regulatory expectation — if anything it raises it, because the transition itself triggers fresh auditing. Two requirements must be built in from the start. First, continuous calibrated temperature logging with accessible records, covering the entire period the product is under the operator's control. Second, documented temperature mapping of each body, identifying the correct sensor locations based on evidence rather than convenience.
- Pre-cool bodies on mains power before loading — never start a route with a warm box.
- Monitor and review logs rather than merely archiving them; recurring patterns indicate body or process problems.
- Re-map after any significant body modification or layout change.
- Define excursion response procedures in writing and brief drivers on them explicitly.
What Does Electric Cold Chain Actually Cost?
| Cost Element (5-year indicative) | Electric | Equivalent Diesel |
|---|---|---|
| Vehicle acquisition | Higher | Lower |
| Energy or fuel | Approx. USD 6,750 electricity | Approx. USD 21,000 diesel |
| Motor or engine maintenance | Approx. USD 1,200 | Approx. USD 5,500 |
| Brake servicing | Approx. USD 200 | Approx. USD 1,800 |
| Oil and filter changes | Zero | Approx. USD 2,200 |
| Charging infrastructure | Depot capital cost | Not applicable |
| Available incentives | Market dependent | Typically none |
Applied to cold chain specifically, the electric case is often stronger than for general delivery, because refrigeration is itself an electrical load — meaning a single electrified system replaces both drivetrain and separate refrigeration drive. Whether the five-year advantage holds in a given market depends on electricity tariffs, available incentives, depot upgrade cost and utilisation; all four should be modelled with local figures before a fleet-wide decision.
How to Decide in Practice
- Measure actual route distances, stop counts and dwell times for your own cold routes — do not plan from averages.
- Calculate refrigeration energy requirement from the body specification and duty cycle, confirmed with the body builder.
- Size the pack so that worst-case day plus refrigeration load completes comfortably within available range, with margin.
- Confirm depot electrical capacity and the realistic overnight charging window before ordering vehicles.
- Specify mains standby refrigeration as standard rather than as an option.
- Run a two-vehicle pilot for three months, instrumented for energy and temperature, before scaling.
That sequence converts an uncertain technology decision into a measured commercial one. Buyers who want deeper platform data can review our SAGMOTO new energy electric trucks range overview, or contact Shaanxi Fenghan Trading for a route-specific energy model and quotation.
Frequently Asked Questions
Which SAGMOTO electric truck is best for urban cold chain?
The SAGMOTO i9 is the better choice for most urban cold chain operations: its light-distribution configuration offers an LFP pack around 96 kWh with a working range near 430 km and approximately 4,500 kg payload at about 12,000 kg GVWR, with enough capacity to run a refrigeration unit alongside driving duty. The i5 suits smaller, shorter inner-city pharmacy routes where its 88 kWh usable pack and roughly 220 km urban range are adequate.
How much range do you lose running refrigeration on an electric truck?
Expect to lose roughly 20-35 percent of usable range when running a refrigeration unit in warm conditions, because the cold unit draws continuously from the traction battery. On the i9 that typically means planning for about 280-340 km rather than the nominal 430 km urban figure, and on the i5 approximately 160-180 km rather than 220 km. Size the vehicle and the unit together, and validate during a pilot before committing a full route.
Is the i5 or i9 better for multi-drop city delivery?
The i5 is better for dense inner-city multi-drop work: its tighter package suits narrow streets, and its 88 kWh usable pack covers typical daily city distances of 120-200 km including refrigeration load. The i9 is better for longer suburban-to-urban routes and higher payloads, where its larger capacity and longer nominal range protect against mid-route charging delays.
What does an electric cold chain truck cost compared with diesel?
Indicatively, an SAGMOTO electric light-distribution truck can show a five-year ownership cost advantage over an equivalent diesel despite higher acquisition, driven by dramatically lower energy and maintenance cost: representative modelling shows roughly USD 6,750 in electricity over five years versus around USD 21,000 in diesel, and around USD 1,200 in motor maintenance versus roughly USD 5,500 for engine maintenance. Whether the advantage holds depends on local electricity tariffs, incentives and depot charging costs.
Can SAGMOTO electric trucks hold cold chain temperatures overnight?
Yes, with mains-connected standby capability specified on the refrigeration unit. Running the cold unit from a mains connection while parked preserves battery charge for driving duty and protects product integrity. Fleets should specify standby compressors and confirm depot electrical capacity before deployment, since relying on traction battery power overnight can leave insufficient range for the first route of the day.
