Abstract

The embodiment of the invention provides a charging system of an electromobile and the electromobile. The charging system comprises a first power battery unit and a buck-boost circuit. The first end of the buck-boost circuit and the first power battery pack are connected. When the second end of the buck-boost circuit is connected with a charging pile, and the maximum output voltage used for the charging pile is less than the battery voltage of the first power battery pack, the output voltage of the charging pile is enlarged; and when the second end of the buck-boost circuit is connected with a second power battery pack of other electromobiles, the voltage of the first power battery pack is output to the second power battery pack. According to the charging system of the electromobile and the electromobile, the problem that the voltage design range of the battery voltage is limited by the output voltage range of the quick charging pile in the prior art is solved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle charging system and the electric vehicle. Background technique [0002] The battery voltage of an electric vehicle must match the output voltage of the fast charging pile before it can be charged. Among them, according to the requirements of the national standard GB / T18487.1, the output voltage of the fast charging pile includes several different voltage ranges such as 200V~500V, 350V~700V and 500V~950V, but because the national standard stipulates the output voltage range of the fast charging pile , which limits the design range of the vehicle’s power battery voltage. For example, if the power battery voltage range is designed to be 300V to 600V, since the power battery voltage range is not in good agreement with the output voltage range of the fast charging pile, then Standard fast charging piles cannot charge the entire vehicle well. [0003] To sum up, i...
