【Abstract】To address the issue of power distributionand vehicle thermal management in Plug-in HybridElectric Bus （PHEB），this paper proposesannergymanagement strategyconsidering thermal coupling.Fistly，a modelofthe powersystem andthermalmanagementsystemofthewholevehicleisconstructed，andthetheralcharacteristicsofkeycomponentssuchas power battryand passenger compartment andtheircoupling relationshipwiththepower system energyflowareanalyzed.On thisbasis，three energy management strategies based onthe Charge-Depleting Charge-Sustaining （CD-CS） strategy，the Pontryagin’s Minimum Principle（PMP）andthe Adaptive Equivalent Consumption Minimization Strategy （AECMS）are designed.Finally，thethreeenergymanagementstrategiesconsidering thermal loadaresimulatedunder typicaloperating conditions.The results show that： under high-temperature （ 35∘C ）operating conditions，the AECMS strategy reduces the comprehensive energy cost per 100km by 5.7% compared with CD-CS; under low-temperature （O ℃）operating conditions，the AECMS strategy reduces the comprehensive cost per 100km by 18.2% compared with the traditional Positive Temperature Coefficient （PTC） heating mode after adopting the engine residual heat prioritized heat generation mode.
