Abstract:In response to the problems of high fuel consumption,high carbon emissions and pollution in traditional fuel mining trucks,a hybrid power system model for extended range mining trucks is established using a series structure architecture based on diesel mining trucks.A composite power following strategy and advanced equivalent consumption minimization strategies(A-ECMS)based on battery state of charge(SOC)feedback are designed.A vehicle model is built based on AVL Cruise,and the control effects of the two energy management strategies are evaluated through joint simulation using MATLAB/Simulink embedded control strategies.The results show that the simulated vehicle speed of the mining truck under both strategies is highly consistent with the required vehicle speed,and the power system can meet the power demand and energy allocation under different operating conditions.Under the A-ECMS strategy,the final SOC of the battery is closer to the target value than the composite power following strategy,with a deviation of only 0.3%and small fluctuations.The equivalent fuel consumption per 100 kilometers is 2.36 L lower than the composite power following strategy.Taking into account the SOC fluctuations of the power battery and the equivalent fuel consumption of the mining truck,the A-ECMS strategy has more advantages.
