According to plowing operation characteristics, a case study on a parallel HET (hybrid electric tractor) with the torque combinator is conducted to develop a plowing operation performance simulation system. The mathematical models of drive equilibrium, battery, power combinator and control system are established respectively. A simulation system for evaluating the tractive performance, fuel economy, battery characteristics and controller performance of HET is developed in the environment of MATLAB/Simulink. Simulation results suggest that: in this HET, the output torque and traction vary in a large range with the variations in the operation modes and SOC level of the battery; in the common interval of SOC (0.4∼0.7), compared with the traditional tractor, HET can achieve larger output torque with a fuel consumption reduction of 18%∼20% in discharge mode; with the capability of keeping the battery charge-discharge stage stable and guaranteeing the SOC variation in a small range, the controller meets with the requirements of plowing operation and benefits the stability of the tractor power and the extension of battery life cycle.
