Abstract

The invention discloses a method for improving the charging efficiency under a complex power supply condition of a charging station transformer, and the method comprises the following steps: S1, obtaining a load of a non-charging region through a charging pile management platform, and calculating the residual load of a pile under the current platform according to the capacity of the transformer; and S2, judging the calculated residual load, if the residual load is smaller than 0, enabling the platform to broadcast and issue the charging pile limited power, and otherwise, enabling the platform to broadcast and issue the charging pile lifting power. According to the method for improving the charging efficiency under the complex power supply condition of the charging station transformer, idle loads of other lines of the transformer are fully utilized, the maximum output power of the charging pile is adjusted in real time through the management platform, a specially-assigned person is not needed for uninterrupted continuous management while it is guaranteed that a user can conduct stable and continuous charging at the normal charging speed, and faults or fire disasters caused by long-time overload of the transformer due to negligence of personnel can be avoided.

Description

technical field

[0001] The invention relates to the technical field of construction of new energy electric vehicle charging stations, in particular to a method for improving charging efficiency under complex power supply conditions of charging station transformers. Background technique

[0002] With the rapid growth of the number of electric vehicles, the construction of charging stations has fallen into a bottleneck. Both the site and the capacity of transformers restrict the construction of charging stations. Therefore, how to maximize the use of transformer capacity to provide charging services for more vehicles is worthy of operation and management. issues considered by the reader.

[0003] At present, in order to improve the utilization rate of the site and serve more vehicles at the same time, as many piles as possible are generally deployed on the market. Considering the problem of transformer capacity, there are three solutions: one is to reduce the power of a single...
