For fleet operators, cold-chain logistics companies, and businesses handling temperature-sensitive deliveries, choosing the right refrigerated vehicle means balancing payload, driving range, refrigeration performance, and operating cost.
Our 4.5T electric refrigerated truck is designed for urban and suburban temperature-controlled delivery, including the transport of fresh produce, dairy products, pharmaceuticals, and other temperature-sensitive goods. It combines a battery-electric powertrain with a dedicated refrigeration system to support daily delivery operations while reducing fuel consumption and routine maintenance costs compared with conventional diesel refrigerated trucks.
Below is an overview of the vehicle’s key specifications and technical features.
1. Strong Power and Gradeability
Urban and suburban delivery routes can involve steep gradients, frequent stops, and varying road conditions. Equipped with a high-performance Permanent Magnet Synchronous Motor (PMSM), this electric refrigerated truck provides:
- Peak Power: 145 kW (75 kW rated)
- Peak Torque: 330 N·m
- Max. Gradeability: ≥25% (at GVW 4,495 kg)
The truck uses a rear-engine, rear-wheel-drive (RR) layout with a 3.5T integrated electric drive axle. By integrating the motor, reducer, and axle into a compact assembly, the electric drive axle reduces drivetrain weight and packaging space while simplifying the overall powertrain structure.
The combination of high motor output and an integrated electric drive axle provides strong low-speed traction and climbing capability, supporting fully loaded delivery operations on routes with frequent gradients and complex urban road conditions.
2. Flexible Battery Configurations & Reliable Range
Operational flexibility is essential for fleet planning. We offer smart power choices tailored to exact operational radii:
- Standard Battery Capacity: 73.14 kWh powered by Gotion (2026 Edition) cells, delivering a practical WLTP driving range of ≥200 km (with 15% SOC remaining).
- Optional Extended Capacity: An optional 115 kWh large-capacity battery pack is available for longer routes.
- Fast Charging: Supports DC Fast Charging to minimize downtime between delivery shifts.
3. 80 mm High-Density PU Thermal Insulation
For cold chain logistics operating in hot and humid climates (such as Southeast Asia, Latin America, and parts of Africa), insulation performance is critical:
- Cargo Box Dimensions: External 4200×2100×2100 mm / Internal 4050×1900×1900 mm, offering an optimized volume for last-mile delivery.
- Advanced Insulation: The cargo box is built with 80mm thick high-density polyurethane (PU) foam panels (density ≥42 kg/m ³). This ensures minimum thermal leakage, keeping perishable goods safe and reducing the workload on the refrigeration unit.
4. Heavy-Duty Chassis: Rugged & Easy to Maintain
Built on a heavy-duty commercial truck foundation rather than a modified passenger platform:
- Suspension: Traditional 3-leaf front and 3+1-leaf rear spring suspension designed for heavy loads and rough road durability.
- Payload Capacity: Gross vehicle weight of 4,495 kg (actual max load up to 2,410 kg), allowing maximum cargo transport without compromising structural integrity.
- Maintenance-Friendly: Features standard dual-circuit hydraulic brakes and a variable cross-section welded frame, ensuring that local mechanics worldwide can service it easily.
