摘要
针对电动汽车启动时所需的大功率、大电流对蓄电池的损害及制动时导致的能量浪费,分析以蓄电池为主电源,具有超大容量的新型储能器件超级电容器为辅助电源的电动汽车能量管理系统。利用两相交错并联双向DC/DC变换器作为超级电容器储能系统的主电路,并采用电压外环电流内环的控制策略对储能系统进行建模仿真。仿真结果表明超级电容器储能响应快,稳定性好,作为电动汽车辅助电源能够实现能量的回收再利用,有效提高系统能量利用率,延长电池使用寿命。
Aiming at the damage of the battery when the electric vehicle starts at high power and large current and the energy waste caused by braking, the electric vehicle energy management system of a battery as a main power source, and a novel type of energy storage device super capacitor with a large capacity as an auxiliary power source is analyzed. A two-phase interleaved parallel bidirectional DC/DC converter is used as the main circuit of the super capacitor energy storage system, and the control strategy of the voltage outer loop current inner loop is adopted to model and simulate the energy storage system. The simulation results show that the super capacitor has fast energy storage and good stability, and can be used as an auxiliary power source of an electric vehicle to realize energy recovery and reuse, effectively improve system energy utilization, and prolong battery life.
