The SAGMOTO i5 is the compact pure-electric commercial vehicle platform designed for the fastest-growing segment in urban logistics: zero-emission last-mile delivery. As cities worldwide implement low-emission zones and carbon-reduction mandates, the i5 provides fleet operators with a practical electric truck that delivers genuine operational savings — not just environmental compliance. With its LFP battery chemistry, integrated electric drive motor, and adaptable body configurations, the i5 is purpose-built for the daily grind of urban distribution.
Electric Powertrain Architecture
The i5 uses a centrally mounted permanent magnet synchronous (PMSM) electric motor driving the rear axle through a single-speed reduction gearbox. This architecture eliminates the multi-speed transmission, clutch, driveshaft, and differential complexity of a diesel truck — reducing drivetrain component count by approximately 60% and eliminating the most common maintenance failure points.
| Specification | i5 Standard | i5 Extended Range |
|---|---|---|
| Motor Type | PMSM (Permanent Magnet Synchronous) | PMSM (Permanent Magnet Synchronous) |
| Peak Power | 120 kW (160 HP equivalent) | 120 kW (160 HP equivalent) |
| Continuous Power | 70 kW | 70 kW |
| Peak Torque | 1000 Nm (instant) | 1000 Nm (instant) |
| Max Speed | 90 km/h (electronically limited) | 90 km/h (electronically limited) |
| 0-50 km/h | 4.5 seconds | 4.8 seconds |
Battery System: LFP Chemistry
The i5 uses Lithium Iron Phosphate (LFP) battery cells — a deliberate choice that prioritizes safety, cycle life, and thermal stability over the higher energy density of NMC (Nickel Manganese Cobalt) chemistry. For commercial vehicle applications where the battery is cycled daily and operates in varying ambient temperatures, LFP's advantages are significant:
| Battery Specification | i5 Standard (98 kWh) | i5 Extended Range (131 kWh) |
|---|---|---|
| Chemistry | LFP (LiFePO4) | LFP (LiFePO4) |
| Usable Capacity | 98 kWh | 131 kWh |
| Nominal Voltage | 345.6V | 345.6V |
| Cell Configuration | 192S2P | 192S2P (additional modules) |
| Estimated Cycle Life | 3,500+ cycles to 80% capacity | 3,500+ cycles to 80% capacity |
| Thermal Management | Liquid-cooled, PTC heating | Liquid-cooled, PTC heating |
| Operating Temp Range | -30°C to +55°C | -30°C to +55°C |
| Working Range (WLTC) | 220 km | 280 km |
The LFP chemistry provides a cycle life exceeding 3,500 cycles to 80% capacity — translating to approximately 10 years of daily operation at 220 km per day. At that point, the battery retains 80% of its original capacity and can either continue in degraded-range service or be redeployed to stationary energy storage. The thermal management system uses liquid cooling with PTC (Positive Temperature Coefficient) heating elements, maintaining battery temperature within the optimal 15-35°C range even in ambient temperatures from -30°C to +55°C.
Charging System
The i5 supports three charging modes:
- DC Fast Charging (CCS2): 60 kW DC charging from 20% to 80% in approximately 60 minutes (standard battery) or 80 minutes (extended range). This is the primary charging mode for commercial fleet operations, allowing mid-shift top-up charging during driver breaks.
- AC Three-Phase (22 kW): Full charge from empty in approximately 5 hours (standard) or 7 hours (extended range). Suitable for overnight depot charging at fleet facilities with 3-phase power supply.
- AC Single-Phase (7 kW): Full charge in approximately 15 hours (standard) or 20 hours (extended range). Backup mode for locations without 3-phase power. Not recommended as primary fleet charging method.
The charging system includes active battery temperature management during charging — pre-conditioning the battery to optimal temperature before high-rate DC charging begins, which protects cell longevity and ensures consistent charging speed regardless of ambient conditions.
Regenerative Braking
The i5 features three-level regenerative braking, selectable by the driver via a steering wheel paddle:
- Level 1 (Light): Minimal regenerative drag, coasting behavior similar to a diesel truck. Best for highway cruising where momentum conservation matters.
- Level 2 (Standard): Moderate regenerative drag providing approximately 12-15% range extension in urban cycles. The default mode for mixed-route delivery.
- Level 3 (Strong): Aggressive regenerative drag allowing one-pedal driving in stop-and-go traffic. Provides approximately 18-22% range extension and reduces brake pad wear by 70-80%. Best for dense urban delivery with frequent stops.
The regenerative braking system also captures energy during downhill descents — a significant advantage in cities with hilly topography where diesel trucks waste energy through friction braking on descents.
Body Configurations
The i5 chassis is designed to accommodate several body types critical to urban logistics:
Box Delivery Van
The most common configuration. Cargo volume ranges from 16 to 28 cubic meters depending on body length. The low frame height (920mm) enables dock-level loading, and the side doors allow curbside parcel delivery without traffic-lane exposure.
Refrigerated Box
The i5's electric powertrain is particularly advantageous for refrigerated delivery: the reefer unit is powered directly from the traction battery via a DC-DC converter, eliminating the diesel reefer engine entirely. This reduces total vehicle noise to near-zero — critical for nighttime urban delivery in residential areas where noise ordinances restrict diesel reefer operation.
Sanitation / Garbage Compaction
The electric hydraulic compactor runs from the traction battery via PTO-equivalent power take-off. The instant torque of the electric motor ensures stable hydraulic pressure during compaction cycles. The zero-emission operation is increasingly required by municipal contracts that mandate low-emission fleet compliance.
Total Cost of Ownership: i5 vs Diesel
| 5-Year TCO Factor | SAGMOTO i5 (Electric) | SAGMOTO E9 (Diesel) | Difference |
|---|---|---|---|
| Acquisition (FOB) | $28,000 - $45,000 | $12,000 - $18,000 | +$16,000 - $27,000 |
| Energy Cost (5yr, 150,000 km) | ~$5,400 ($0.036/km) | ~$21,000 ($0.14/km) | -$15,600 |
| Maintenance (5yr) | ~$2,200 | ~$6,000 | -$3,800 |
| Brake Pads (5yr) | ~$120 (1 replacement) | ~$560 (4 replacements) | -$440 |
| 5-Year TCO | ~$39,000 | ~$45,000 | -$6,000 |
Charging Infrastructure Requirements
Fleet operators considering the i5 should plan for depot charging infrastructure. The minimum requirement for a 10-truck i5 fleet is:
- Electrical supply: 3-phase 400V AC, minimum 250 kVA transformer capacity (for simultaneous 10-truck overnight AC charging at 22 kW each)
- Charging stations: 10 × 22 kW AC wall-mounted chargers (approximately USD 1,500-2,500 each installed) or 3 × 60 kW DC fast chargers (approximately USD 15,000-25,000 each installed) for rotating fast-charge operations
- Smart load management: A charging management system that distributes available power across multiple trucks, preventing transformer overload and optimizing charging schedules based on next-day route assignments
For fleets without depot charging capability, public DC fast charging networks in major cities increasingly support commercial vehicle charging, though at higher per-kWh rates (typically USD 0.08-0.12/kWh vs USD 0.03-0.05/kWh at depot rates).
Conclusion
The SAGMOTO i5 electric light truck is purpose-built for the economics of urban last-mile delivery. Its LFP battery delivers the cycle life and safety that commercial fleet operators demand, the instant torque of the PMSM motor improves delivery productivity, and the total cost of ownership turns positive within 3 years of operation. As cities worldwide accelerate their transition to zero-emission logistics, the i5 provides a practical, economical path for fleet operators to lead that transition rather than be forced into it by regulation.
