Description

Technical Field

[0001] This application relates to the technical field of electric vehicles, and particularly to a method and device for vehicle battery swapping in a battery swapping station for electric vehicles. Background Art

[0002] Fuel vehicles need to use petroleum resources as power, consuming petroleum resources and generating a large amount of polluting gases. Electric vehicles, with in-vehicle power sources as the power supply, have relatively less impact on the environment compared to traditional fuel vehicles. Their prospects are widely favored and there is a trend to replace fuel vehicles.

[0003] A large number of electric vehicle operating vehicles have been put on the market and entered the usage stage. However, the following problems have emerged: The number of charging stations and charging piles is small and in short supply. If a large number of electric vehicles enter the charging station to wait for charging, it will cause congestion and waste of resources in the station, and at the same time affect the usage experience of electric vehicles.

[0004] Therefore, a method and related device are needed to store fully charged battery modules in the charging station. When a vehicle that needs to be charged enters the charging station, it can store and retrieve battery modules independently to achieve fast and controllable battery swapping. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a method and device for vehicle battery swapping in a battery swapping station for electric vehicles with high battery swapping efficiency and controllable management.

[0006] A method for vehicle battery swapping in a battery swapping station for electric vehicles provided by this application includes the following steps:

[0007] Step 1: An electric vehicle drives into the battery swapping station. The battery swapping controller in the electric vehicle communicates with the battery swapping server in the battery swapping station. The battery swapping controller sends a battery swapping request signal to the battery swapping server and waits for a response.

[0008] Step 2: The battery swapping server responds to the battery swapping request signal sent by the battery swapping controller and allows the electric vehicle that sent the battery swapping request signal to perform a battery swapping operation. If the battery swapping server does not respond to the battery swapping request signal sent by the battery swapping controller, or the response is not allowed, then: The battery swapping controller resends the battery swapping request signal and sends it multiple times within a certain period until the battery swapping server responds as allowed. If the battery swapping server fails to respond within the timeout period or still responds as not allowed, the staff in the battery swapping station will perform manual intervention. Among them, the battery swapping server records the communication connection data with the battery swapping controller and the relevant information of the battery swapping controller.

[0009] Step 3: Guide the electric vehicle allowed to respond to approach the battery storage cabinet in the swapping station, and bring the battery module removed from the electric vehicle close to the RFID reader in the swapping station, so that the RFID reader can identify and read / write the RFID tag on the battery module; wherein, the RFID reader records the interaction information with the battery module and the relevant information of the battery module, and uploads them to the swapping server;

[0010] Step 4: Unlock the battery storage cabinet in the swapping station, allow the identified battery module to be put in, and put in the identified battery module;

[0011] Step 5: Take out another fully charged battery module, and then lock the battery storage cabinet;

[0012] Step 6: Bring the taken-out battery module close to the RFID reader in the swapping station, so that the RFID reader can identify and read / write the RFID tag on the taken-out battery module, and install the identified battery module; wherein, the RFID reader records the interaction information with the battery module and the relevant information of the battery module, and uploads them to the swapping server;

[0013] Step 7: After the swapping operation is completed, the swapping controller on the electric vehicle sends a swapping completion signal to the swapping server and disconnects the connection, and the electric vehicle drives away from the swapping station; wherein, the swapping server records the communication connection data with the swapping controller and the relevant information of the swapping controller.

[0016] Preferably, an RFID tag is installed on the battery module; an RFID reader is installed near the battery storage cabinet in the swapping station for identifying and reading / writing the relevant information of the battery module.

[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] The method for realizing swapping in the swapping station for electric vehicles of the present invention can reliably handle complex situations when multiple vehicles drive into the swapping station simultaneously, without the need for on-site manual command intervention, and has good management controllability.

[0019] The electric vehicle of the present invention uses a battery swapping controller, and a battery swapping server is introduced into the battery swapping station. After the battery swapping controller, as a client, successfully connects to the battery swapping server at the battery swapping station end, it responds to the instructions issued by the battery swapping server and performs corresponding actions, so as to accurately cooperate with the battery compartment cabinet to achieve the action of replacing the battery module.
