The invention relates to a power supply system for quickly charging an electric vehicle and a charging and discharging method thereof. The power supply system comprises a super capacitor energy storage system, a super capacitor management module, a rectifying device and a power battery pack, when the electric automobile is charged, the external source charging device charges the super capacitor energy storage system, and the super capacitor energy storage system of the electric automobile quickly obtains the required electric energy until the electric automobile is fully charged by utilizing the characteristic that the charging time of the super capacitor is short; each super capacitor module of the super capacitor energy storage system independently and sequentially discharges electricity to the power battery pack, and the power battery pack can receive the electric energy of the super capacitor module to be charged while driving; and the electric vehicle quickly obtains required electric energy from the external source charging device and gradually transfers the electric energy to the power battery pack, so that the problem of long charging time of the electric vehicle is solved.

    本发明涉及一种电动汽车快速充电的电源系统及其充放电方法,包括:超级电容器储能系统、超级电容管理模块、整流装置、动力电池组;当电动汽车充电时,外源充电装置给超级电容器储能系统充电,利用超级电容器充电时间短的特性,电动汽车超级电容器储能系统快速获得所需的电能,以至充满电,当外源充电装置与电动汽车断开后,超级电容器储能系统的每个超级电容器模组,分别独立地依次放电给动力电池组,动力电池组可以一边行驶一边接收超级电容器模组的电能充电;电动汽车快速从外源充电装置获得所需的电能,逐步转移到动力电池组,由此解决电动汽车充电时间长的问题。
