the battery management system BMS is used for packaging the charging pile ID and the related information of the battery to be charged into a first message and respectively sending the first message to the charging pile and the remote monitoring platform; the charging pile forwards the first message to an authentication chip;
the authentication chip is used for encrypting the first message to form a second message, and the second message is forwarded to the remote monitoring platform through the charging pile;
and the remote monitoring platform is used for decrypting the second message, and if the decrypted charging pile ID and the battery related information are consistent with the charging pile ID and the battery related information sent by the battery management system BMS, the charging certification of the charging pile for the battery to be charged is determined to be successful.
7. The charging authentication system of claim 6, wherein the charging post is connected to the authentication chip in a pluggable manner.
8. The charging authentication system of claim 6, wherein the charging post is wirelessly connected to the authentication chip.
9. An authentication chip comprising a memory and a processor;
the memory is used for storing executable program codes;
the processor is used for reading the executable program code stored in the memory to encrypt a first message to form a second message, and the second message is forwarded to the remote monitoring platform through the charging pile, wherein the first message is formed by packaging the ID of the charging pile and the related information of the battery to be charged by the battery management system BMS.
10. A computer-readable storage medium, comprising instructions that, when executed on a computer, cause the computer to perform encrypting a first message into a second message, and forwarding the second message to a remote monitoring platform via a charging pile, wherein the first message is a message formed by packaging an ID of the charging pile and information related to a battery to be charged by a battery management system BMS.
