Abstract

The invention discloses a charging method and device of a charging station. The charging method of the charging station comprises the steps that the state parameter in initial time of a target time period of the charging station and a charging load curve mode corresponding to the initial time are obtained; according to the charging load curve mode, an average load is determined; according to the state parameter and the average load, the target rated charging power of a charging pile in the charging station in the target time period is computed; and the charging pile is controlled to charge a first electric car according to the target rated charging power in the target time period, wherein the first electric car is an electric car which is charged currently by the charging pile. The problems that in the prior art, a plurality of electric cars are connected into a power grid for charging in disorder randomly, so that the power grid is not stable or safe are solved, and therefore the effect of power grid safety and stability improving is achieved.

Description

technical field [0001] The invention relates to the field of charging stations, in particular to a charging method and device for a charging station. Background technique [0002] Electric vehicles have the characteristics of high efficiency and cleanness, and can reduce oil dependence and exhaust emissions. my country's "Energy Saving and New Energy Vehicle Industry Development Plan (2011-2020)" proposes that the number of electric vehicles should reach 5 million by 2020. The large-scale application of electric vehicles is an inevitable development trend in the future society, but the charging behavior of electric vehicles is uncertain in time and space. The load growth of the wheel will make the operation and control of the power grid more difficult, affect the power quality, and endanger the safety and stability of the power grid. [0003] Aiming at the problem that large-scale electric vehicles are randomly and disorderly connected to the grid for charging in related te...
