Abstract

This application is applicable to the field of battery technology, and provides a battery authentication method, device, terminal equipment and medium. The method includes: when a super battery is detected, sending a first authentication request to the super battery; When the super battery responds to the first authentication data returned by the first authentication request, generate first authentication information according to the first authentication data, and send the first authentication information to the super battery; when receiving the first authentication information When the second authentication request returned by the super battery, send the second authentication data to the super battery; receive the second authentication information returned by the super battery for the second authentication data, and according to the second authentication information, Authenticate the super battery; if the super battery is successfully authenticated, perform a charge or discharge operation on the super battery. Through the above method, the security of authentication between the battery and the charging and discharging device can be improved.

Description

technical field [0001] The present application belongs to the field of battery technology, and in particular relates to a battery authentication method, device, terminal equipment and medium. Background technique [0002] The battery exchange cabinet can provide charged batteries for electric vehicles. At present, when changing the battery, the identity between the power changing cabinet and the battery only needs to be confirmed through data communication, and then charging can be carried out. After the battery is installed on the electric vehicle, it can be discharged only after data communication. [0003] However, there is only data transmission between the charging and discharging device and the battery, which makes the battery easy to be cloned. In the existing communication, when the communication data between the charging and discharging equipment and the battery is monitored, after a long period of analysis, the communication rules can be deciphered, and the batte...
