Row charging, to realize that charging pile charges to the personalization of battery.
That is, can utilize in range monitoring platform database with the associated historical data of target vehicle battery to target
Vehicular battery is analyzed, and is obtained for suggestions such as personalized charging, maintenance and the maintenances of target vehicle battery, to realize to mesh
The intelligent supervision for marking Vehicular battery to improve the charging experience of user, and avoids using generalization mode charging modes meeting
Cause that life time decay is very fast, overcharges, the poor equivalent damage of battery consistency to percentage of batteries.
In addition, the charging that can not only be improved battery to be charged using the charging authentication method in the embodiment of the present invention is pacified
Entirely, and the charge data of charging pile can be safely and accurately uploaded in remote monitoring platform database and is associated with battery
Data area, to be provided with the data supporting of effect for further battery charging analysis.
In an alternative embodiment, for convenience of the update and upgrading to charging pile, between trusted authentication chip and charging pile
It can make insertable connection type.That is, there are the openings being inserted into for trusted authentication chip in charging pile, filled when needing to increase
The function of electric stake or need to the application program in trusted authentication chip carry out upgrading optimization when, it is only necessary to the trusted authentication chip is taken
Go out, upgrading is updated using special equipment.It is of course also possible to the trusted authentication chip need not be taken out, but by pre-
If data-interface be updated upgrading.
In some optional embodiments, between trusted authentication chip and charging pile can also be wirelessly connected (for example, bluetooth,
Internet of things or 4G networks etc.) so that the installation site of trusted authentication chip has certain flexibility.Certainly, to reduce cost, recognize
It can also be wired connection to demonstrate,prove between chip and charging pile.
For ease of it will be appreciated by those skilled in the art that the decryption to the ciphering process of trusted authentication chip and remote monitoring platform below
Process illustrates.
By taking the authorization of digital authenticating as an example, remote monitoring platform can be that the charging pile authorized issues digital certificate,
Digital authenticating is stored in trusted authentication chip corresponding with charging pile.Trusted authentication chip can utilize the private key in digital certificate to important
Information is signed, and the corresponding public key of each private key, utilization and information sender can accordingly, in remote monitoring platform be remained with
Transmission information after (charging pile) corresponding public key signs to it is decrypted.
The ciphering process of trusted authentication chip can be understood as：Using the private key in digital certificate to including charging pile ID and vehicle
The message of relevant information is digitally signed, and digital signature and former message are sent to remote monitoring platform.In former message also
It is numbered including digital certificate.
The decrypting process of remote monitoring platform can be understood as：Judge digital certificate according to the digital certificate number received
Whether it is whether digital certificate that CATL is issued and the digital certificate are effective, if the digital certificate is the digital certificate that CATL is issued
And the digital certificate is effective, then the digital certificate for obtaining and receiving from stored data numbers consistent public key, then
Digital signature is decrypted using public key.
It should be noted that trusted authentication chip in the embodiment of the present invention can also using other types cipher mode, this
Place is without limiting.
