However, due to the lack of comprehensive planning, the built electric vehicle charging stations are generally different, and the current carrying capacity of the charging lines corresponding to different electric vehicle charging stations is also different, and there is no such thing in the existing electric vehicles. An electric vehicle charging system that can match the maximum current-carrying capacity of the charging line by adjusting the required power of its own charger. Therefore, in the actual charging process of the existing electric vehicle, if the on-board charger of the electric vehicle It is easy to cause a safety accident if the charging connection line is used to obtain a large current.

The invention discloses a charging system for an electric vehicle and an electric vehicle. The charging system comprises an on-board charger, a charger controller and a whole vehicle controller which are connected with a charging control device in a charging station through a charging line, wherein the whole vehicle controller is respectively connected with the charger controller and the charging control device and is used for detecting a voltage signal of a voltage-dividing resistor on the charging line and converting the voltage signal into a corresponding current-carrying capacity value for transmission; the charger controller is arranged in the on-board charger and is used for receiving the current-carrying capacity value and adjusting the demand power of the on-board charger according to the current-carrying capacity value; the charger controller is also used for generating a control signal according to the demand power of the adjusted on-board charger; and the control signal is used for triggering the charging control device to charge the on-board charger. Through the charging system, the electric vehicle can be safely charged by using charging cables with different specifications.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, and more specifically, to an electric vehicle charging system and the electric vehicle. Background technique [0002] At present, as the world's oil resources become more and more scarce, major international and domestic automobile companies are devoting themselves to the development of new energy vehicles to advocate energy saving and emission reduction. At present, pure electric vehicles, as a new energy vehicle, have been greatly promoted and applied, and have formed a certain industrial scale. [0003] With the development of electric vehicles, many electric vehicle charging stations have emerged as the times require. However, due to the lack of comprehensive planning, the built electric vehicle charging stations are generally different, and the current carrying capacity of the charging lines corresponding to different electric vehicle charging stations is also different, and there...
