Problems solved by technology
[0004] In the process of researching the existing technology, the inventor found that the expert experience method is difficult to standardize. When there are many divisions in the charging facility construction planning area, there are many repetitive tasks, and it is difficult to quickly replicate the expert experience; it is impossible to evaluate and effectively monitor the expert decision-making ; Excessive reliance on expert experience, high labor costs, if there is a lack of experienced experts, it will bring great difficulties to the construction and planning of charging facilities

The invention discloses a method and a device. The method includes: separately obtaining charging power curves of m charging construction planning areas, and the charging power curves are charging facilities in the charging construction planning areas calculated according to statistics, and charging capacity curves in a preset period m is a positive integer; cluster m charging curves to obtain typical charging power curves of type g, wherein, g≤m, g is a positive integer; for each type of typical charging power curves Screen the charging influencing factors to determine the charging influencing factors of each type of typical charging capacity curve; according to the charging influencing factors of each type of typical charging capacity curve and the charging capacity data of each charging construction planning area, predict the charging capacity of each planning area . It can be seen that the application scheme realizes the prediction of the charging power data in the charging construction planning area by obtaining the charging power curve of the charging construction planning area, clustering the charging power curve and screening the charging influencing factors.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a charging electric quantity prediction method and device. Background technique [0002] Vigorously developing electric vehicles is of great significance to ensuring energy security, promoting energy conservation and emission reduction, preventing and controlling air pollution, and cultivating new economic growth points and international competitive advantages. A sound charging facility system is an important guarantee for the development of electric vehicles. Therefore, how to accurately deploy charging facilities in the planning area for charging facility construction has become a technical problem to be solved urgently by those skilled in the art. [0003] In the prior art, most of the charging facilities are planned based on the expert experience method. The so-called expert experience method refers to the method based on subjective judgment, and subjectively judges...
