Embodiment 1
[0028] In the first embodiment of the present invention, the pile platform and the vehicle platform integrated with the mobile phone APP are used in actual use. figure 1 and figure 2 AC charging pile 1 is a family intelligent AC charging pile, the new energy vehicle 2's car battery management system 21 real-time discharge signal of the battery of the new energy vehicle 2, and uploads the car platform 3, the car platform 3 judge the new energy vehicle 2 Whether it is in a state in which-reverse charging, if so, the vehicle platform 3 initiates reverse charging prompts to the user. When the user receives a prompt, it can choose whether or not to perform reverse charging, or select Reverse Power to the grid or select the reverse storage to home or directly to the home appliance. Specifically, when the power supply is too high, the power grid load is too high, and the user can feed the grid; and when the power grid is loaded, the excess amount can be stored to the household storage de...

The invention provides an AC charging pile V2G system and method. The AC charging pile V2G system comprises an AC charging pile and a vehicle networking platform. The alternating current charging pile is used for charging the new energy vehicle or reversely returning electricity; the new energy vehicle comprises a bidirectional OBC module; the vehicle networking platform comprises a power grid power-back mode and a household power storage mode; the power grid electricity returning mode refers to that the new energy vehicle reversely discharges electricity to the alternating current charging pile through the bidirectional OBC module, and the alternating current charging pile returns the electricity to the power grid; the household electricity storage mode refers to that the new energy automobile reversely discharges electricity to the alternating current charging pile through the bidirectional OBC module, and the alternating current charging pile stores the electricity to household electricity storage equipment. According to the AC charging pile V2G system, V2G is realized based on the AC charging pile, the power is relatively low, and the system is more suitable for household power storage in regions with dispersed regions and difficult power stability maintenance, and the application range is wider. And moreover, the electric energy is reasonably scheduled, the utilization rate of resources is improved, and the waste of the resources is avoided.
Description
Technical field [0001] The present invention relates to the field of new energy vehicles, and more particularly to an AC charging pile V2G system and method. Background technique [0002] V2G is an abbreviation for Vehicle-to-Grid (vehicle to grid). V2G describes the relationship between electric vehicles and grids. When the electric car is not in use, the electric energy of the car battery is sold to the power grid. If the vehicle battery needs to be charged, the current flows from the grid to the vehicle. [0003] At present, the programs of V2G related to this field are electric vehicles to achieve reverse discharge through DC charging piles. However, the DC charging pile is installed and the operation and maintenance cost is high. The battery loss is large, and does not apply to the needs of household storage, especially the dispersion of rural towns and towns, and the difficulty of stabilizing the stability of the grid. [0004] And considering the power supply of the chargi...
