Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] The power intelligent adjustment method of the charging device includes the following steps:

[0020] (1) if figure 1 As shown, the initial charging time of the electric vehicle is extracted, the charging time is calculated according to the initial charging time, the daily mileage of the electric vehicle is extracted, the state of charge of the electric vehicle is calculated, the electric vehicle load is calculated based on the Monte Carlo method, and the load curve is drawn.

[0021] (2) According to step (1), draw the load curves of multiple electric vehicles of the same type, and judge whether the load curves converge. If the load curves converge, output the load curves. If not, repeat the operation step (1).

[0022] (3) Determine the maximum output power of the entire charging station according to the load curve of the electric veh...

Abstract

The invention discloses an intelligent power regulating circuit and method of charging equipment. The method comprises the steps that firstly, the state of charge (SOC) of electric vehicles and loads of the electric vehicles are worked out, and load curves are drawn; by drawing the load curves of the multiple electric vehicles of the same type, whether the load curves are astringed or not is judged, if the load curves are astringed, the load curves are output, and if the load curves are not astringed, the operations are carried out repeatedly; and according to the load curves of the electric vehicles, the maximum output power of a whole charging station is determined, a decision model is established for all terminal charging equipment through the analytic hierarchy process according to the SOC of the electric vehicles, the charging process is divided into an energy supplement stage, a power maintaining stage and a low current supplement stage, and powers of all charging ports are distributed dynamically. By the adoption of the intelligent power regulating circuit and method, the charging loads of the electric vehicles can be forecast effectively, orderly charging control is achieved by sufficiently using a charger, flexible and rapid charging of the electric vehicles is guaranteed, and meanwhile, regional load monitoring is also taken into account.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to an intelligent power adjustment method for charging equipment. Background technique [0002] Electric vehicles refer to vehicles powered by batteries, fuel cells or supercapacitors, all or part of which are driven by electric motors. They are the fusion product of electrification and automobiles. Electric vehicles can be broadly divided into the following three types, namely hybrid electric vehicles, fuel cell electric vehicles and pure electric vehicles. A hybrid electric vehicle refers to a vehicle that is equipped with more than two power sources (such as batteries, fuel cells, internal combustion engines, etc.), including motor-driven vehicles that comply with road traffic safety regulations. At present, the plug-in hybrid electric vehicle is widely used to drive the electric motor with the battery after it is fully charged. After the battery on the vehicle is us...
