Research on Battery Power Supply System of Extended-range Electric Tractor
The extended-range electric tractor has the advantages of energy saving and emission reduction,long range and so on,but the existing power battery pack voltage level is low and cannot meet the DC bus voltage demand of the entire extended-range electric tractor.In this paper,the power battery power supply system is studied for the demand of 500 V voltage platform of the whole machine of the extended-range electric tractor,and the hardware design and control design of the power battery power supply system are completed,and finally the simulation is verified by using MatLab/Simulink.In terms of simulation experiments,the designed power battery power supply system achieves good step-up voltage stabili-zation control and closed-loop DC power supply effect from 320 V to 500 V,and is able to adapt to the demand of parallel and equal-current power supply with other power sources such as range-extender,and the power battery power supply system has good dynamic performance and steady-state performance to meet the demand of stable power supply.
