Abstract

The invention discloses a control method and device for charging an electric vehicle. Wherein, the method includes: obtaining the battery parameters of the rechargeable battery of the car to be charged, wherein there are one or more cars to be charged, and each car to be charged includes one or more rechargeable batteries; determining the charging power of the rechargeable battery based on the battery parameters According to the charging power curve, calculate the cumulative number of batteries that have been fully charged at each moment; generate a charging time series based on the load data of the power station, the cumulative number of fully charged batteries, and the charging power curve; control the car to be charged to charge according to the charging time series. The embodiment of the present invention solves the problem that the plug-and-charge electric vehicle charging mode in the prior art greatly increases the load on the power grid and threatens the safety of the power grid, realizes the orderly control of the charging of the car to be charged, and reduces the power consumption of the power station. The compliance improves the security of the power grid.

Description

technical field [0001] The invention relates to the field of charging control, in particular to a method and device for controlling charging of an electric vehicle. Background technique [0002] With the increasing promotion and popularization of electric vehicles, the impact and impact of charging on the grid has gradually emerged. In the uncontrolled plug-and-charge mode, the charging load of electric vehicles is likely to overlap with the user's evening power consumption peak, and the real load valley at night cannot be effectively utilized. [0003] Large-scale electric vehicle charging will affect the operation of the power grid. Unreasonable charging rules will deteriorate the operating environment of the power grid, increase network losses and voltage fluctuations, and even threaten the safety of the power grid. [0004] Aiming at the problem that the plug-and-charge electric vehicle charging mode in the prior art greatly increases the load of the power grid and thre...
