Embodiment Construction

[0046] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0047] Here, it should be noted that, in this embodiment, image 3 The charging and discharging control method is realized on the basis of the connection between the shown bidirectional charger 1 and external components such as the battery management system 2 .

[0048] Specifically, the two-way charger 1 is electrically connected to the discharge button 3, and is used to receive a discharge request signal input by the user through the discharge button 3, wherein the discharge button 3 is a button with an LED light. When the electric vehicle is discharged according to the discharge request signal, the two-way charger 1 outputs a driving signal to control the LED indicator light of the discharge button 3 to light up.

[0049] The bidirectional charger 1 ...

Abstract

The invention provides a charging and discharging control method, device, bidirectional charger and electric vehicle, and relates to the field of vehicle control technology. The method includes: after the charging gun is connected, obtaining the charging connection of the charging gun to confirm the resistance signal of the CC terminal And obtain the detection voltage on the control guide CP line of the charging gun; determine the charging and discharging mode of the electric vehicle according to the resistance signal and the detection voltage; send the corresponding charging and discharging mode to the battery management system control signal. According to the obtained resistance signal and the detected voltage, the solution of the present invention realizes intelligent identification of the current charging and discharging mode of the electric vehicle, improves user experience, and makes charging and discharging more intelligent.

Description

technical field [0001] The invention belongs to the technical field of complete vehicle control, and in particular relates to a charge and discharge control method, device, bidirectional charger and electric vehicle. Background technique [0002] With the development of economy and technology, the proportion of electric vehicles in the automobile market is increasing. Users have higher and higher requirements for the convenient charging of electric vehicles and the charging of other loads by electric vehicles. Based on the above requirements, automobile manufacturers decide to Develop the vehicle-to-load discharge (abbreviation: V2L) function, and the vehicle-to-vehicle discharge (abbreviation: V2V) function. [0003] In view of the fact that AC charging and V2V functions use the same vehicle interface, it is impossible to use a mechanical structure to prevent mistakes in inserting the gun. If the user is reminded by marking (such as the color of the gun head connected to th...
