基于HEV再生制动超级电容参数研究

Research of super capacitor parameters based on HEV regenerative braking

受体积限制,混合动力电动汽车携带的动力型蓄电池数量有限,且蓄电池功率密度较低,导致其一次充电行驶里程相对较短。为提高能源利用率,延长混合动力电动汽车的一次充电续驶里程,提出了基于DSP2812复合电源驱动系统,并根据制动模型设计了复合电源系统超级电容的参数,并对复合能源系统进行了实验研究。

Subject to size constraints,the hybrid electric vehicles can carry a limited number of batteries with low power density,resulting in a relatively short mileage in a single charge cycle.To improve energy using efficiency and extend HEV mileage in a single charge cycle,the synergic electric power supply driving system based on DSP2812 was proposed.Super capacitor parameter was designed according to HEV regenerative braking model.The experiments were realized based on synergic electric power supply.
