Abstract

The invention discloses an electromobile power supply device and a motor vehicle. The electromobile power supply device comprises a bridge type rectification circuit, the bridge type rectification circuit is used to charge a super capacitor, and the super capacitor serves as an energy storage device to charge an external battery pack of electromobile. According to the invention, disadvantages in the prior art are overcome, a power supply function of the electromobile is realized in a power-grid-free or power supply environment, and the stability of the charging power supply is improved.

Description

technical field [0001] The invention relates to the field of emergency power supply for electric vehicles, in particular to a power supply device for electric vehicles and a motor vehicle. Background technique [0002] The existing electric vehicle power supply methods are generally powered by grid charging piles and charging stations, which have been widely used as conventional electric vehicle power supply methods. However, it has high load requirements on the power grid, and the charging speed of electric vehicles is relatively slow. At the same time, during the use of electric vehicles, if the battery power of the electric vehicle is not enough to drive the vehicle, and there is no power grid, charging pile or charging station near the electric vehicle, the vehicle cannot be charged. [0003] In the prior art, Chinese invention patents CN 204012784 U and CN 201750181 U disclose two kinds of mobile charging vehicles, which realize flexible and convenient charging of elec...
