Research and optimization on global energy management strategy of E-REV
Dijkstra algorithm was applied to the global energy management strategy of extended-range electric vehicles(E-REVs)with the optimization objective of the whole vehicle's fuel economy.The simulation results of China Light Commercial Vehicle Operating Condition(CLTC-C)showed that,Dijkstra algorithm took about 40%of the time of dynamic programming;The endpoint of the algorithm Dijkstra must be the given SOC endpoint,while there was a certain error between the value of the endpoint of dynamic programming and the given SOC value.Considering the engine start-stop loss and minimum working time,the engine start-stop frequency was reduced by about 40%,and the engine working condition was improved,which was more in line with the practice and fuel economy was also improved.
