In an open test field, our technical team conducted a comprehensive field test on the E22 electric dozer. The tests covered power output, hydraulic system stability, battery performance, and adaptability to rugged terrain, verifying the reliability and efficiency of this zero-emission construction equipment in actual operating conditions.
Our engineers, wearing safety gear, tested the E22 electric dozer on uneven ground and sloping terrain. They tested the machine's starting performance, pushing force, steering flexibility, and continuous operation capability. The quiet operation of the 200kW permanent magnet synchronous motor (PMSM) eliminates the noise common to diesel dozers, allowing for precise control and clear communication among team members during the test.


The E22 is equipped with a 200kW permanent magnet synchronous motor (200Nm torque) and a 423.94kWh lithium iron phosphate (LiFePO4) battery pack (614.2V, 690Ah). During the test, the walking motor controller (210kW, 800AAC) provided stable power output even under heavy load conditions. The three-gear pump hydraulic system, driven by a 50kW permanent magnet motor, delivered smooth and powerful lifting and pushing performance, meeting the requirements of typical dozing operations with a 30MPa working pressure.
The field test also evaluated the performance of the E22's integrated thermal management system (TMS). The TMS cooling system, based on an 8kW compressor, 45kW plate-fin radiator, and electric control air conditioning, worked together to maintain optimal operating temperatures for the battery pack and motor even during continuous operation. The customized VCU controller monitors all parameters in real-time to ensure the system operates within safe limits throughout the test.
The E22's track chassis demonstrated excellent stability on rugged and sloping terrain. Engineers tested the dozer's climbing ability, traction, and maneuverability, finding that the machine operates reliably under all conditions. Safety features such as the CAN communication insulation monitor, high-voltage shielded cables, and Starlight night vision 360° panoramic imaging system were also verified, providing comprehensive protection for operators during field operations.


Following the successful field test, our factory team confirms that the E22 electric dozer meets all performance and reliability standards. With its 200kW power, large-capacity battery, efficient hydraulic system, and intelligent control, it delivers zero-emission, low-noise, and high cost-performance in various construction environments.
