The transition from diesel to electric commercial vehicles is no longer a future possibility — it is a present reality reshaping urban logistics fleets worldwide. The SAGMOTO i9 electric light truck is SAGMOTO's dedicated entry into this segment, engineered from the ground up as a battery-electric platform rather than a converted diesel chassis. With a 430-kilometer working range, 120KW DC fast charging, an integrated electric drive axle, and brake energy recovery delivering a 15 percent reduction in energy consumption, the i9 is purpose-built for the stop-go, low-speed, high-frequency duty cycles that define last-mile delivery and municipal operations. This article provides a comprehensive technical analysis of the i9 platform and a five-year total cost of ownership comparison against an equivalent diesel light truck.
Integrated Electric Drive Axle Technology
The defining engineering feature of the SAGMOTO i9 is its integrated electric drive axle (e-axle). In a conventional electric truck conversion, the electric motor is bolted to a standard drive shaft and differential assembly borrowed from a diesel platform — a layout that adds weight, consumes chassis space, and introduces multiple mechanical loss points. The i9's e-axle eliminates the drive shaft entirely by integrating the permanent magnet synchronous motor (PMSM), the reduction gearbox, and the differential into a single compact unit mounted directly on the rear axle.
This integration delivers three measurable benefits. First, it reduces drivetrain weight by approximately 60 to 80 kilograms compared to a shaft-driven layout, directly increasing payload capacity. Second, it eliminates the mechanical transmission losses of a drive shaft and universal joints, improving overall efficiency from battery to wheel by an estimated 4 to 6 percent. Third, it frees up chassis space between the axles, allowing the battery pack to be mounted centrally in the frame for optimal weight distribution and a lower center of gravity — critical for the stability of a high-profile cargo body in urban maneuvering.
The PMSM motor produces a peak output of 167 kW (224 horsepower equivalent) and a continuous rated output of 120 kW, with peak torque of 1100 Nm available from zero RPM. This instantaneous torque delivery is the single most noticeable operational difference for drivers transitioning from diesel — the i9 accelerates from 0 to 50 km/h in approximately 8 seconds at full payload, comparable to or faster than a diesel light truck of equivalent GVWR.
Battery System and Working Range
The i9 is equipped with a lithium iron phosphate (LFP) battery pack with a total energy capacity of 96 kWh. LFP chemistry was selected over nickel-manganese-cobalt (NMC) alternatives for two reasons: superior thermal stability, which is critical for trucks operating in high-ambient-temperature urban environments, and significantly longer cycle life — LFP cells typically deliver 3,000 to 4,000 charge cycles to 80 percent capacity, compared to 1,500 to 2,000 for NMC cells. This translates to a battery service life of 8 to 10 years under typical urban logistics duty cycles, aligning with or exceeding the vehicle's economic service life.
The i9 delivers a working range of 430 kilometers on a full charge under the China City Bus Coach Test (CCBC) cycle, which closely approximates real-world urban delivery conditions — frequent stops, low average speeds, and regenerative braking opportunities. Under highway conditions at constant 80 km/h, the range extends to approximately 500 kilometers. For a typical urban delivery route covering 120 to 180 kilometers per day, the i9 can complete a full shift with more than 50 percent battery reserve, eliminating range anxiety and enabling overnight-only charging.
120KW Fast Charging: 65 Minutes to 80 Percent
The i9 supports 120KW DC fast charging via a CCS2 (Combined Charging System) connector, charging from 20 percent to 80 percent state of charge in approximately 65 minutes. A full charge from 0 to 100 percent requires approximately 90 minutes on a 120KW charger. For fleets operating two shifts, a midday top-up during the driver's break restores sufficient range for the afternoon shift without requiring a second vehicle.
The battery management system (BMS) actively balances cell voltage and temperature during charging, preventing the thermal degradation that plagues poorly managed fast-charging systems. The BMS also supports 7KW AC slow charging (full charge in approximately 14 hours), which is the recommended overnight charging method for depot-based fleets — slow charging generates less heat and extends battery calendar life compared to daily fast charging.
Brake Energy Recovery System
The i9's brake energy recovery system (regenerative braking) is one of its most impactful efficiency features, delivering a measured 15 percent reduction in overall energy consumption under urban duty cycles. When the driver releases the accelerator or applies the brake, the electric motor switches to generator mode, converting the truck's kinetic energy into electrical energy that is fed back into the battery. In urban delivery, where a truck may stop and start 200 to 300 times per shift, this recovered energy is substantial.
The system operates in two modes. In "coast regeneration" mode, lifting off the accelerator engages a mild regenerative drag that slows the truck progressively — many drivers find they can complete urban routes using the accelerator alone, touching the friction brakes only for final stops. In "brake regeneration" mode, pressing the brake pedal blends regenerative and friction braking, with the BMS prioritizing regenerative capture up to the motor's generator capacity limit before engaging the friction pads. Beyond energy savings, this dramatically reduces brake pad wear — a maintenance cost that is effectively eliminated for the first 100,000 kilometers in typical urban use.

Ideal Use Cases
The i9 is engineered for specific operational profiles where electric drive delivers its maximum advantage. These are the applications where the i9 outperforms diesel on both cost and operational capability:
- Last-mile parcel and e-commerce delivery: Stop-go urban routes of 100-200 km per day with 50-200 delivery stops. Regenerative braking captures energy at every stop, and silent operation enables extended delivery windows.
- Municipal services: Waste collection, street cleaning, and parks maintenance vehicles that operate on fixed urban routes with depot return. Electric drive eliminates noise and local emissions in residential neighborhoods.
- Cold chain urban distribution: The refrigerated variant's electric compressor runs independently of the drive system, maintaining temperature during stops without engine idling — a legal requirement in many low-emission zones.
- Campus and corporate logistics: University campuses, industrial parks, and airport ground operations with fixed circuits and centralized charging.
- Corporate ESG fleets: Companies with public sustainability commitments where measurable emission reductions support ESG reporting and brand positioning.
Charging Infrastructure Requirements
Deploying the i9 requires depot charging infrastructure. For a fleet of 5 to 10 vehicles, the recommended setup includes one 120KW DC fast charger for opportunistic mid-shift top-ups and a bank of 7KW AC wall boxes for overnight slow charging of each vehicle. The AC wall boxes draw from standard three-phase industrial power and do not require grid upgrades in most commercial premises. The 120KW DC charger requires a dedicated 150 kVA power connection and should be specified in consultation with the local utility provider.
Fleets should not rely on public charging infrastructure for operational planning — public DC chargers in most emerging markets remain sparse and unpredictable. The i9 is designed for depot-based charging as the primary energy supply model, with public charging as an emergency fallback only.
Market Availability
The SAGMOTO i9 is available for export through authorized channels including Fenghan Trading. Market availability depends on destination-country homologation and EV incentive frameworks. Fenghan Trading provides consultation on homologation requirements, charging infrastructure planning, and fleet transition strategies for buyers transitioning from diesel to electric. For markets without established EV support infrastructure, a phased deployment — starting with 2 to 3 i9 units alongside existing diesel fleet — is recommended to validate operational suitability before full fleet conversion.
Conclusion
The SAGMOTO i9 represents a genuine engineering commitment to electric urban logistics rather than a compliance exercise. Its integrated e-axle, LFP battery system, 430-kilometer range, and 120KW fast charging form a coherent technical platform that delivers measurable operational advantages over diesel in the urban duty cycle. The five-year TCO comparison confirms that the higher purchase price is recovered through energy and maintenance savings, with government incentives accelerating the payback. For fleet operators in markets where urban emission regulations are tightening, where diesel costs are high, and where depot charging is feasible, the i9 is not just the future of urban logistics — it is the present. The transition begins with a conversation about your specific routes, payloads, and charging infrastructure, and Fenghan Trading is positioned to guide that transition from specification to deployment.
