The locomotive adopts a hybrid power mode of catenary + traction battery. During dynamic braking, kinetic energy can be converted into electrical energy and fed back to the grid or used to charge the traction battery, effectively recovering surplus energy and improving energy utilization efficiency. Compared with traditional diesel shunting locomotives, it achieves higher transmission efficiency, with no diesel engine noise and no pollutant emissions, making it more environmentally friendly.
