🔋 E22 272HP Pure Electric Medium Bulldozer

The E22 272HP electric medium bulldozer is a high-performance, zero-emission green construction machine built for modern low-carbon job sites. This 272-horsepower medium electric bulldozer uses a premium permanent magnet synchronous motor, a high-capacity lithium iron phosphate battery pack, and a fully intelligent electronic control system. It delivers strong driving force, achieves zero exhaust emissions and ultra-low operating noise, and significantly reduces daily operating costs, making it an ideal environmentally friendly earthmoving machine for green projects.

⚡ Core Power System: 272HP Main Motor & High-Capacity Battery

The E22 272HP electric bulldozer is driven by a 200kW (272HP) high-power permanent magnet synchronous motor with stable torque of 200Nm, paired with a 614.2V, 690Ah 423.94kWh lithium iron phosphate battery pack and a customized intelligent BMS management system. The travel motor controller supports 210kW power and 800AAC current, ensuring stable power output even under heavy-load conditions. It supports 2×300kW battery interfaces, 2×250A DC fast charging, 2×400kW DC discharge, and multiple auxiliary power supplies for battery heating and stable low-voltage circuit operation.

🫧 Hydraulic and Working System: Auxiliary 68HP Drive and High-Efficiency Hydraulic Assembly

The hydraulic system is independently driven by a 50kW (68HP) permanent magnet synchronous hydraulic motor with 280Nm torque, paired with a hydraulic pump reducer with 10000rpm input speed, 800Nm output torque, and a gear ratio of i=3.656. It is equipped with a 100+65+25 triple gear pump with helical gear structure and a standard working pressure of 30MPa. This configuration provides ample hydraulic power for dozing, lifting, and ripping operations, with high efficiency and low-noise performance.

🤖 Intelligent Control and Thermal Management System

The E22 272HP electric bulldozer is equipped with an exclusively customized VCU controller using a 14nm 32-bit processor, supporting 22 analog inputs, 20 digital inputs, 6 frequency inputs, and 6 CAN communication channels, with abundant expansion ports. It integrates a complete thermal management system including an 8kW compressor TMS cooling system, a 2.5kW fresh air cooling system, and a 10kW electronically controlled air conditioner with a 47cc scroll compressor and EER 2.7 energy efficiency. The liquid cooling system uses a 45kW plate-fin radiator and a 400W PWM water pump, keeping the battery and motor operating at optimal temperatures at all times.

🛡️ Safety and Monitoring Configuration

It is equipped with a professional CAN communication insulation monitor featuring 2500Vac withstand voltage and 10ms fast leakage detection, combined with high-voltage shielded cables and metal waterproof connectors for high-standard high-voltage safety protection. The vehicle monitoring system includes a 128GB dashcam, a 4G remote monitoring TBOX module, and a 7-inch LCD interactive screen, paired with 2 starlight night-vision cameras for a 360° panoramic view. It features an audible and visual alarm system and electronically controlled damping structure, enabling stable operation in various harsh construction environments.

🌱 Core Environmental and Operational Advantages

As a fully electric 272HP medium bulldozer, it completely eliminates exhaust emissions and significantly reduces noise pollution. Compared with diesel bulldozers of the same horsepower, it greatly lowers daily operating costs. The comprehensive thermal management and high-density battery pack enable stable operation in extremely high and low temperature areas. The power and hydraulic sections adopt a modular design, simplifying routine maintenance and effectively reducing equipment downtime.

📍 Main Application Scenarios

This 272HP E22 electric medium bulldozer is widely used in urban municipal construction, environmental protection projects, green mining operations, and indoor low-noise demolition projects with strict low-carbon requirements. It is also highly suitable for construction equipment rental businesses and government-supported green low-carbon construction projects, perfectly meeting various environmental construction needs.
