Problems solved by technology

[0002] At present, in order to realize the rapid energy replenishment of the vehicle, the charging current value also increases accordingly, but according to the national standard GBT27930-2015 for DC charging, the maximum current is 400A, which cannot meet the current fast-growing charging demand. Therefore, based on GBT27930-2015 Partially modify the DC charging process to meet the higher charging current, but the revised standard does not support the charging of vehicles that only meet the national standard, which also brings corresponding troubles to users and needs to be resolved urgently

Embodiment Construction

[0046] It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict.

[0047] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0048] figure 1 It is a flowchart of a vehicle charging method according to an embodiment of the present invention.

[0049] like figure 1 As shown, the vehicle charging method according to the embodiment of the present invention includes the following steps:

[0050] In step S101, it is detected whether a charging connection is established between the vehicle and the charging device.

[0051] It should be understood that in order to achieve high-power charging compatible with the DC charging solution specified in the national standard GBT27930-2015, a version negotiation process needs to be added before the charging process is started. After the agre...

Abstract

The invention relates to the technical field of vehicles, in particular to a vehicle charging method and device and a vehicle. The method comprises the steps that whether charging connection is established between the vehicle and charging equipment or not is detected; after it is detected that the charging connection is established, version negotiation information sent by the charging equipment is received; and according to the version negotiation information, negotiating an optimal version allowed to be charged of the vehicle, and controlling the charging equipment to charge the vehicle according to the optimal version allowed to be charged. According to the vehicle charging method provided by the embodiment of the invention, high-power charging of the vehicle can be realized, the charging efficiency of the vehicle is improved, the charging time is shortened, and conditions are provided for efficient energy supplementation.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a vehicle charging method, device and vehicle. Background technique [0002] At present, in order to realize the rapid energy replenishment of the vehicle, the charging current value also increases, but according to the national standard GBT27930-2015, DC charging is carried out, and the maximum current is 400A, which cannot meet the current rapid development of charging needs. Therefore, based on GBT27930-2015 The DC charging process is partially modified to meet the larger charging current, but the revised standard does not support charging vehicles that only meet the national standard, which also brings corresponding problems to users, which needs to be solved urgently. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to provide a vehicle charging method, which can realize high-power charging of the vehicle, improve the charging eff...
