Embodiment 1

[0032] Such as figure 1 As shown, the orderly charging control system of the present invention consists of three parts: a regional power grid dispatching system, an electric vehicle demand response management system, and an electric vehicle charging pile.

[0033] The regional power grid dispatching system receives the information of all charging piles sent by the electric vehicle demand response management system, including the current total charging power, maximum charging power and minimum charging power. Treating all charging piles as a controllable load, the regional power grid dispatching system formulates a dispatching plan based on conventional power generation, distributed renewable energy generation forecast, load forecast, real-time charging power of electric vehicles and charging demand, etc. Charging power P p .

[0034] The electric vehicle demand response management system is based on the dispatch plan formulated by the regional power grid dispatch p , compreh...

Embodiment 2

[0050] Now assume that there are N charging piles connected to the electric vehicle demand response management system, and some electric vehicles choose to participate in demand response, corresponding to orderly charging piles; some electric vehicles choose not to participate in demand response, corresponding to conventional charging piles.

[0051] Among them, the charging power of the ordered charging piles takes a value between its minimum charging power and the maximum charging power, and the charging power of each ordered charging pile does not exceed its maximum charging power, according to the dispatching system formulated by the grid dispatching system The planned charging power is allocated among the orderly charging piles.

[0052] For conventional charging piles, the demand power and benchmark electricity price are used for charging; for ordered charging piles, preferential electricity prices are dynamically generated according to the limit of their charging power. ...

Abstract

The invention relates to an electric car charging control method and a charging pile. Two options, namely, accepting the demand response management and rejecting the demand response management, are provided for users. The method includes: determining whether the user accepts the demand response management or not through the charging pile according to user's operation, if so, then determining the charging power of the charging pile through an electric car demand response management system; if not, then determining the charging power of the charging pile through the car in charging; and further,charging the car needing to be charged according to the charging power of the charging pile. On the basis of full use of the existing distribution network resources, the method realizes orderly guideand dynamic adjustment control on output real-time power of the charging pile, guides the charging behavior of the electric car to transit into an ordered charging mode from a single-way out-of-orderrandomly charging mode, realizes peak shaving of the power grid, realizes charging on peak shifting, reduces load fluctuation of the power grid, reduces energy consumption of the power grid, improvesreliability of the distribution network and increases economic benefit thereof.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an electric vehicle charging control method and a charging pile. Background technique [0002] Energy and environmental issues are long-term common challenges faced by the international auto industry. With the gradual increase of the current global environmental protection, due to the inevitable environmental pollution in the use of traditional fossil energy, its use is decreasing day by day. Green and clean energy has become a hot spot in the world today, and automotive products will become more and more safe. , energy saving, and environmental protection, new energy vehicles have become the goal and pursuit of competing research and development by various countries. [0003] As the trend of clean energy today, new energy vehicles are a new type of green transportation, which has incomparable advantages over traditional vehicles. It has less impact on the...
