Problems solved by technology
The common feature of these two solutions is that the charging stand and the vehicle-mounted BMS need wireless wifi communication. In the existing technical solutions, only wireless communication is realized, but there is no solution when the ratio of n:n between the station-type charging stand and the vehicle to be charged appears. The problem of ensuring a precise handshake between the two, for example: No. 1 car is parked under No. 1 charging rack, but No. 1 car may be connected to the wireless signal of No. 2, No. 3, etc. charging racks
If you operate according to the charging process at this time, there will be a situation where it cannot be charged, or even a high voltage danger will occur.

Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0028] Such as figure 1 As shown, the new energy vehicle charging method of this embodiment is applicable to the situation where there are multiple charging racks 1 and multiple vehicles 2 to be charged at the charging station, wherein each charging rack 1 corresponds to an independent wireless network (such as a wifi network) , the charging method specifically includes the following steps:
[0029] S01. When the vehicle to be charged 2 is located in the charging area of the charging rack 1 (that is, the area where the vehicle to be charged 2 can be charged with the charging rack 1, specifically, the pantograph 401 and the substrate 402 are located at the same position), the charging rack Identification between 1 and the vehicle 2 to be charged;
[0030] S02. After the identity recognition between the charging stand 1 and the vehicle to be ...

The invention discloses a new energy vehicle charging method. The method comprises the following steps that: S01, when a to-be-charged new energy vehicle is located in a charging area of a charging rack, identity recognition is carried out between the charging rack and the to-be-charged vehicle; S02, after the identity recognition between the charging rack and the to-be-charged vehicle succeeds, one-to-one communication connection is established between the charging rack and the to-be-charged vehicle; and S03, the charging rack charges the to-be-charged vehicle in one-to-one communication connection with the charging rack. The invention further discloses a new energy vehicle charging system. The system comprises charging racks; each charging rack is correspondingly provided with a wirelesswifi network; a recognition unit is arranged between each charging rack and each to-be-charged vehicle and is used for identity recognition between the charging rack and the to-be-charged vehicle ina corresponding charging area, so that the charging rack and the to-be-charged vehicle in the corresponding charging area are in one-to-one communication connection through the wireless wifi network.The new energy vehicle charging method and system have the advantages of high safety, high reliability and the like.
Description
technical field [0001] The invention mainly relates to the technical field of new energy vehicles, in particular to a charging method and system for new energy vehicles. Background technique [0002] With the development of new energy vehicles, the charging method is becoming more and more intelligent, efficient and safe. Therefore, a platform fast charging system based on pantograph charging has been developed. The platform charging system and the vehicle BMS rely on wireless wifi. Network communication. There are two schemes for domestic pantograph charging, one is that the pantograph is installed on the vehicle, and the receiving substrate is installed on the platform charging rack; the other is that the pantograph is integrated on the platform charging rack , is charged by the bow bow installed on the roof of the electric substrate. The common feature of these two solutions is that the charging stand and the vehicle-mounted BMS need wireless wifi communication. In the ...
