The invention relates to the technical field of electric automobiles, and provides an electric automobile charging device and an electric automobile, in the electric automobile charging device, a second contactor, a first storage battery pack, a first contactor, a second storage battery pack and a third contactor are sequentially connected in series, one end of the second contactor is connected with one end of a charging port of the electric automobile, and the other end of the second contactor is connected with the other end of the charging port of the electric automobile. And one end of the third contactor is connected with the other end of the charging port, so that when the first contactor, the second contactor and the third contactor are all closed, the first storage battery pack and the second storage battery pack are connected in series, the charging voltage can be greatly improved, the charging time is shortened, the wire diameter does not need to be increased, and related high-voltage components do not need to be upgraded. And the charging cost is saved.
本发明涉及电动汽车技术领域,提供一种电动汽车充电装置及电动汽车,所述电动汽车充电装置中第二接触器、第一蓄电池组、第一接触器、第二蓄电池组以及第三接触器依次串联,其中,第二接触器的一端与电动汽车的充电端口的一端连接,第三接触器的一端与充电端口的另一端连接,从而在第一接触器、第二接触器以及第三接触器均闭合时,实现了第一蓄电池组与第二蓄电池组串联,不仅能够大幅度提高充电电压,缩短充电时间,而且不需要加大线径、升级相关高压部件等,节约了充电成本。
