Optimization of APU Start-stop Control for Diverse Mileage Ranges
For a range-extended electric vehicle,a multi point energy management strategy was de-veloped to meet different demands of power and energy.Then an optimization model of APU was for-mulated to achieve the target of minimum fuel consumption.In the constraints of performance index of range-extended electric vehicle and battery cycle life,optimization of control parameters of APU start-stop was performed by the SIMULINK model with diverse mileage ranges under different driv-ing cycles to realize APU start-stop control for adaptive range.Compared with before optimization,the results show that fuel consumption is reduced by 15.87%/2.09%,42.24%/14.54% respectively corre-sponding to NEDC100/200,CUDC100/200.Based on energy consumption comparisons before and af-ter optimization,the fuel economy may be obtained through reducing APU operation time under the condition of single loads and transferring operation time from peak loads to medium loads and low loads under the condition of multiple loads.
