The invention discloses a system and a method for battery swapping between a battery swapping station and a vehicle terminal through Bluetooth communication. The system comprises a barrier gate system used for acquiring vehicle identity information; a background server which is used for authenticating the identity of the vehicle; a vehicle communication end, which is used for communication between a vehicle and a battery swap station or a barrier gate; a battery swap station communication end which is used for communication between the battery swap station and a vehicle or a barrier gate; a Bluetooth communication module which is used for establishing Bluetooth communication; and a protocol analysis module which is used for analyzing various messages defined by the protocol and assembling the messages. By means of the system and the method, the feed condition of the storage battery of the whole vehicle in practical application can be effectively avoided; besides, secondary identity authentication is carried out on the vehicle information to ensure reliability; thirdly, the power conversion process can be timely followed up by periodically interacting the state information of the power conversion process; and moreover, the vehicle is allowed to drive away after the multi-dimensional comprehensive judgment of the vehicle state before the battery replacement is started and the normal connection state of the new battery system is judged after the battery replacement action is completed, so that the battery replacement process is safe and reliable.
Description
technical field [0001] The invention belongs to the field of automobile communication, and in particular relates to a system and method for exchanging electric power between a power exchange station and a car end through Bluetooth communication. Background technique [0002] At present, the charging time of electric vehicles is too long compared with the refueling time of traditional fuel vehicles. The industry is vigorously developing the rapid replacement technology of power battery packs, especially for operating vehicle users, which can greatly shorten the charging time. At present, only the automation of the battery replacement process has been realized in the industry, and the degree of automation of the preparatory work before the battery replacement is not high, such as confirming whether the vehicle meets the battery replacement status, starting the battery replacement, etc. [0003] CN111885135A discloses a system and method for automatically replacing batteries, i...
