Problems solved by technology
The application publication also only considers one-way charging piles. Although the method of segmented processing is adopted, the initial charging time is randomly selected according to the probability, which is not accurate, and does not take into account the user's departure time and the target power level at the time of departure. Including, not fully combined with user needs

Embodiment Construction
[0050] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0051] Such as figure 1 As shown, a two-way charging and discharging control system for electric vehicles includes a video monitoring unit, a microgrid control center and multiple two-way charging piles:
[0052] The video monitoring unit includes a vehicle identification module A1 and a communication module A2, wherein the vehicle identification module A1 is mainly used to complete vehicle identification. Taking the video monitoring system of a smart city as an example for illustration, the smart city connects the entire system to the Internet. When an electric vehicle drives When entering the parking space, the camera automatically collects vehicle information and uses relevant algorithms to realize vehicle identity identification. After completing the identity information identification of the entering vehicle, the vehicle identity informa...

The invention relates to a bidirectional charging and discharging control system and method for an electric vehicle. The control system comprises a video monitoring unit, a microgrid control center and a plurality of bidirectional charging piles, wherein one end of the bidirectional charging pile is connected with the video monitoring unit and the microgrid control center, the other end of the bidirectional charging pile is connected to the electric vehicle, the video monitoring unit and the microgrid control center are connected with each other, and the video monitoring unit is used for identifying identity information of the electric vehicle; the microgrid control center is used for calculating the optimal charging and discharging strategy of each electric vehicle; and the bidirectionalcharging pile guides orderly charging and discharging of the electric vehicle according to the optimal charging and discharging strategy. Compared with the prior art, the microgrid control center is constructed by adopting the bidirectional charging piles based on a game theory method and a segmented charging mechanism, and the optimal charging and discharging strategy is calculated by combining the demand information of the electric vehicle, so that the purpose of automatically and accurately guiding the orderly charging and discharging of the electric vehicle is realized, the charging cost can be effectively reduced, and the safe and economic operation of the microgrid is facilitated.
Description
technical field [0001] The invention relates to the technical field of charging and discharging of electric vehicles, in particular to a bidirectional charging and discharging control system and method for electric vehicles. Background technique [0002] With the rapid development of the electric vehicle industry, a large number of on-board batteries have become an important mobile energy storage unit in the grid. Due to the randomness and intermittent nature of the charging behavior of electric vehicles, if there is no reasonable allocation and guidance strategy, the unconstrained charging behavior of a large number of electric vehicles will increase the power supply pressure of the power grid, resulting in increased load peaks, increased peak-to-valley differences, and Increased frequency fluctuations and other issues have a great adverse impact on the safety, economy, stability and reliability of the grid, and weaken the grid's ability to serve electric vehicles. [0003...
