双能量源纯电动汽车能量管理系统建模研究

摘要

Aiming at the problem of energy management modeling of dual-energy storage system of the battery and the super capacitor, structures and working processes of the energy management system of the pure electric vehicle were analyzed. It was studied that the working modes, the power of power and resistance, and operating constraints of pure electric vehicle with dual-energy storage system. The mathematical model of the dual-energy management system of the pure electric vehicle was established. And the energy management control strategy was proposed.%针对蓄电池-超级电容双能量源存储系统能量管理建模问题，对双能量源纯电动汽车能量管理系统的结构和工作过程进行了分析。分析了蓄电池-超级电容纯电动汽车的四种工作模式，车辆行驶中的阻力功率，能量管理系统的功率以及运行约束条件，对能量管理系统进行了建模研究，给出了双能量源纯电动汽车能量管理系统数学模型，并提出了能量管理控制策略。
