Embodiment Construction
[0026] The invention provides an electric vehicle and its DC charging system, which is used to solve the problem of complicated operation caused by opening the main switch of the vehicle when the electric vehicle is charged according to the EU charging standard.
[0027] To achieve the above object, the technical solution provided by the invention is:
[0028] A DC charging system for an electric vehicle, including a charging interface and a charging gun presence detection module;
[0029] The charging gun presence detection module is connected to the charging interface for detecting whether there is a charging gun connected to the charging interface;
[0030] The charging gun presence detection module is also provided with a signal output interface, and the signal output interface is used to connect the control part of the vehicle main fire switch;
[0031] When the charging gun presence detection module detects that the charging gun is connected to the charging interface, a...

The invention provides an electric vehicle and a direct current charging system thereof. The electric vehicle comprises a charging interface and further comprises a charging gun in-place detection module; the charging gun in-place detection module is connected with a charging interface and used for detecting whether a charging gun is put into the charging interface or not; a signal output interface is also formed in the charging gun in-place detection module; the signal output interface is used for being connected with a control part of a vehicle ignition switch; and when the charging gun in-place detection module detects that the charging gun is put into the charging interface, a control command of controlling the vehicle ignition switch to be turned off is transmitted to the control partof the vehicle ignition switch via the signal output interface. Due to the technical scheme of the invention, the vehicle ignition switch can be automatically turned on after the charging gun is inserted into the charging interface, the vehicle is electrified without labor, and therefore, the manual intervention in the charging process is reduced, and the charging operation complexity level is reduced.
Description
technical field [0001] The invention belongs to the technical field of electric vehicle charging control, and in particular relates to an electric vehicle and a DC charging system thereof. Background technique [0002] Electric vehicles are vehicles that use power batteries as the power source. Compared with vehicles powered by traditional energy sources, they have the advantages of environmental protection and energy saving. Today, the environment is deteriorating and traditional energy sources are gradually consumed. It is considered to be the most ideal. means of transportation. [0003] Due to the limited capacity of the power battery used in electric vehicles, in order to ensure the endurance of the vehicle, it needs to be charged in time when the power of the power battery is too low. With the rapid development of electric vehicles, the charging technology of electric vehicles has gradually become a key factor affecting whether electric vehicles can be widely populari...
