Increment Dynamic Adjustment Method for Hybrid Energy Source System in Electric Vehicles

To solve the power flow management problem of two energy sources in a composite energy source system, a incremental dynamic optimization method is proposed in this paper. The incremental adjustment criteria are studied and the penalty coefficients is introduced to optimize the increment. Further, the realization of the energy management strategy of an electric bus equipped with CHS hybrid power system is presented. The bus was tested on the bench with CCBC condition and operates on bus lines. And the test results and operating data demonstrate the effectiveness and robustness of the proposed method.
