Port Terminal Electrification Trend
Ports worldwide are accelerating the adoption of zero-emission equipment as part of decarbonization commitments under the World Ports Climate Action Program (WPCAP). Major ports including Rotterdam, Los Angeles/Long Beach, Singapore, and Dubai have committed to zero-emission terminal operations by 2030-2035. Electric trucks for container drayage and intra-terminal logistics are a critical component of this transition, replacing diesel yard trucks that contribute 15-25 percent of port-related emissions. The SAGMOTO i9, with its 131 kWh LFP battery and 280 kW motor, is purpose-built for port terminal duty cycles. For the full SAGMOTO new energy electric trucks range, visit our product page.
Port Terminal Duty Cycle Analysis
Port terminal container drayage operations have a distinctive duty cycle that is well-suited to electric trucks:
| Duty Cycle Parameter | Typical Port Drayage | i9 Capability |
|---|---|---|
| Daily distance | 150-250 km | 220-250 km range |
| Average speed | 15-25 km/h | Optimal for EV efficiency |
| Container moves per day | 15-25 | Adequate for 24h operation |
| Stop frequency | Every 8-15 minutes | Ideal for regen braking |
| Payload per move | 20-30 tonnes (container) | 14t payload + trailer |
| Operating hours | 16-24 hours/day | Multiple shift charging |
| Route predictability | Fixed routes within port | Enables route-based charging planning |
The i9's 220-250 km range covers a full 8-hour shift of container drayage, with charging during driver breaks and shift changes. The predictable, fixed routes within port terminals simplify charging infrastructure planning, as charging stations can be placed at strategic locations along the drayage route.

| GVW | 25,000 kg (tractor) | Container trailer compatible |
| Fifth-Wheel | JOST JSK 42 | Standard container trailer coupling |
| Frame | 8+8mm double HT steel | Terminal abuse tolerance |
| Brake System | Regen + air, ABS | Controlled stops with container |
| Charging | CCS2, 120 kW DC fast | 45-minute opportunity charging |
| Cab | Day cab, air suspension seat | Driver comfort for shift work |
Charging Infrastructure for Port Operations
Depot Charging Strategy
The recommended charging strategy for port terminal operations is depot-based opportunity charging during natural operational pauses:
- Shift change (30-45 minutes): Fast charge at 120 kW DC, adding 90-110 kWh (70-80 percent charge) during the 30-45 minute shift changeover
- Driver break (15-20 minutes): Top-up charge at 120 kW DC, adding 30-50 kWh during driver rest breaks
- Overnight (6-8 hours): Full charge at 22 kW AC, replenishing 100 percent charge for the morning shift
- Opportunity charging (5-10 minutes): Quick top-up at 120 kW during container loading/unloading delays
| Charging Event | Duration | Energy Added | Charge Level |
|---|---|---|---|
| Shift change fast charge | 30-45 min | 90-110 kWh | 20% to 90% |
| Driver break top-up | 15-20 min | 30-50 kWh | 50% to 75% |
| Overnight AC charge | 6-8 hours | 131 kWh | 0% to 100% |
| Opportunity charge | 5-10 min | 10-20 kWh | 60% to 70% |
Energy Consumption in Port Duty Cycle
Port drayage energy consumption is lower per kilometre than general freight due to the regenerative braking benefit of frequent stops and the relatively low average speeds. The i9's energy consumption in port operations:
| Operating Mode | Energy Consumption | Daily Energy (8h shift) |
|---|---|---|
| Container drayage (loaded) | 0.65 kWh/km | 130 kWh (200 km) |
| Container drayage (empty return) | 0.45 kWh/km | 90 kWh (200 km) |
| Yard maneuvering (loaded) | 0.80 kWh/km | 80 kWh (100 km) |
| Idle (container loading/unloading) | 2 kWh/h | 16 kWh (8h idle time) |
| Total daily (8h shift) | 0.60 kWh/km avg | 131-140 kWh |
The daily energy consumption of 131-140 kWh matches the i9's 131 kWh battery capacity, meaning the truck requires at least one opportunity charge during the shift to complete a full 8-hour drayage cycle. With a single 30-minute shift-change fast charge adding 90-110 kWh, the truck operates with 50-70 percent battery margin throughout the shift.
24-Hour Operations
For ports operating 24 hours with 3 shifts, the charging strategy is:
| Shift | Hours | Charging Strategy | Battery at Shift End |
|---|---|---|---|
| Day shift | 06:00-14:00 | Start at 100%, opportunity charge at 10:00 | 40-50% |
| Shift change | 14:00-14:30 | 120 kW DC fast charge | 85-90% |
| Evening shift | 14:30-22:30 | Opportunity charge at 18:30 | 45-55% |
| Shift change | 22:30-23:00 | 120 kW DC fast charge | 80-85% |
| Night shift | 23:00-06:00 | Opportunity charge at 02:00 | 30-40% |
| Shift change | 06:00-06:30 | 120 kW DC fast charge | 85-90% |
This 24-hour operation cycle maintains battery above 30 percent at all times, preventing deep discharge damage and ensuring consistent performance. The battery's 3,000-cycle life at 100 percent DoD translates to 6,000+ cycles at 70 percent DoD (typical port duty cycle), providing 10+ years of service life in 24-hour operations.

Zero-Emission Zone Compliance
Major ports are implementing zero-emission zones that restrict or prohibit diesel truck operations:
- Port of Los Angeles/Long Beach: Zero-emission truck mandate by 2035, with interim targets of 40 percent by 2027
- Port of Rotterdam: Zero-emission zones in terminal areas by 2030
- Port of Singapore: Green Port Programme with reduced port dues for zero-emission vehicles
- Port of Dubai (DP World): Carbon neutral terminal operations by 2040, with interim targets
The i9's zero tailpipe emissions ensure compliance with all current and planned zero-emission zone regulations, future-proofing the fleet against regulatory changes. Additionally, the i9's low noise operation (65 dB at 7 metres vs 80+ dB for diesel) enables extended operating hours in noise-sensitive port-adjacent areas, increasing terminal throughput.
Conclusion
The SAGMOTO i9 electric truck is purpose-built for port terminal container drayage and yard logistics operations. Its 131 kWh LFP battery provides full-shift range with opportunity charging, the 280 kW motor delivers instant torque for loaded container starts, and the regenerative braking system captures 20-25 percent of braking energy in the frequent-stop port duty cycle. With annual operating savings of USD 15,600-17,100 per truck and a payback period of 2.3-2.6 years, the i9 delivers compelling economics for port operators transitioning to zero-emission operations. As zero-emission zone regulations tighten at major ports worldwide, the i9 provides a proven, reliable platform for port terminal electrification, supported by SAGMOTO's commercial vehicle engineering experience and Shaanxi Fenghan Trading's coordination with charging infrastructure partners.
