SINOTRUK Lithium Battery System of the HOWO G7X EV 342 kWh High-Roof Electric Tractor Truck

• Battery type: Lithium iron phosphate (LFP).
• Battery capacity: 342 kWh.
• Maximum charging power: 250 kW.
• Charging method: Direct charging.
• Charging time: 1.5 hours.
• Driving range: 260 km under mixed loaded and unloaded operating conditions.

The vehicle uses the European CCS2 charging standard and supports dual-gun DC fast charging. CCS2 is widely used in Vietnam and is compatible with almost all charging stations. Dual-gun fast charging also reduces charging downtime and improves vehicle utilization.

Electric Motor System of the HOWO G7X EV 342 kWh High-Roof Electric Tractor Truck

• Motor model: 2 × TZ220XS-ZQV13.
• Motor type: Permanent magnet synchronous motor.
• Installation position: Axles 2 and 3.
• Rated power: 2 × 150 kW.
• Rated torque: 2 × 265 N·m.
• Rated speed: 5,405 rpm.
• Maximum power: 2 × 275 kW.
• Maximum torque: 2 × 500 N·m.
• Maximum speed: 12,000 rpm.

AMT Transmission

• Model: MCE12ZG.
• Transmission configuration: 2 forward gears and 1 reverse gear.
• Transmission type/control: Mechanical transmission with automatic shifting.

The automated manual transmission (AMT) offers several advantages:

• Retains the key benefits of a conventional stepped manual transmission, including a simple structure, long service life, high reliability and high transmission efficiency.
• Automates the gear-shifting process, reducing driver workload and improving driving convenience.
• Can be integrated with an internal combustion engine control system to help reduce fuel consumption and environmental pollution.
• Is particularly effective in tractor trucks equipped with multi-speed transmissions, including 12-speed configurations.

MAN-Technology Axle System of the HOWO G7X EV 342 kWh High-Roof Electric Tractor Truck

• Front axle: VGD71S, with a load capacity of 7.1 tonnes.

The VGD71S is a premium SINOTRUK axle incorporating MAN technology. It features maintenance-free wheel bearings and offers approximately 15% greater load-bearing capacity than the HF07 axle.

• Rear axle: MCE12ZG, with a load capacity of 12 tonnes.

The MCE12ZG is a new-generation SINOTRUK axle designed for electric vehicles featuring an integrated motor, transmission and axle assembly.

With fewer drivetrain components, the integrated axle assembly is more compact and lightweight, delivers higher transmission efficiency and provides an immediate torque response. Its more rigid structure also helps reduce noise and vibration.

Chassis and Suspension System of the HOWO G7X EV 342 kWh High-Roof Electric Tractor Truck

Front suspension

• Dependent suspension with two leaf springs, hydraulic shock absorbers and a stabilizer bar.
• Equipped with an automatic brake shoe clearance adjuster.
• Designed to provide a comfortable ride, making it well suited to long-distance transportation.

Rear suspension

• Dependent suspension with three leaf springs and single leaf-spring shackles.
• Equipped with an automatic brake shoe clearance adjuster.
• Designed to provide a comfortable ride, making it well suited to long-distance transportation.

Additional Systems of the HOWO G7X EV 342 kWh High-Roof Electric Tractor Truck

Regenerative Braking System

The energy recovery control switch is located on the right side of the steering column, with settings ranging from OFF to levels 1–5. At the OFF setting, no energy is recovered during coasting. From level 1 to level 5, the level of energy recovery during coasting increases progressively.

ASR/ESC System

On the SITRAK G7X EV electric tractor truck, the ASR and ESC functions are integrated into a single control switch, enabling coordinated operation of the Electronic Stability Control (ESC) and Anti-Slip Regulation (ASR) systems.

As both systems share actuators that apply braking and adjust individual wheel speeds under different operating conditions, they help correct oversteer and understeer, maintain the driver’s intended direction of travel and limit wheel spin.

FCW/LDW Systems

Forward Collision Warning (FCW) operates within a defined vehicle speed range, typically from 5 to 130 km/h. The system uses information about stationary and moving objects, together with vehicle speed, operating status and steering inputs, to assess potential collision risks and provide warnings.

Lane Departure Warning (LDW) uses a forward-facing camera to detect lane markings and process lane-position data. The system calculates the relevant control outputs to help keep the vehicle within its lane.

Anti-lock Braking System (ABS)

The Anti-lock Braking System (ABS) is an important vehicle safety feature designed to prevent wheel lock-up and skidding when braking forces exceed the available tire-road grip under demanding braking conditions.

ABS is commonly fitted to the front axle of vehicles to help maintain steering control. On the HOWO G7X EV 342 kWh High-Roof Electric Tractor Truck, however, ABS is installed across all three axles, including the steering axle and both drive axles. This configuration helps maintain vehicle control while reducing the risk of the tractor’s rear end and attached semi-trailer deviating from their intended path when braking on poor road surfaces.
