CAN bus, electric car has passed through CAN bus and has connect with charging pile at this time), electric vehicle and charging pile, which have been provided with, at this time fills
The precondition of electricity；
Whether the accumulative charging degree of BMS judgement inside step 4, electric vehicle reaches set meal total value, and such as accumulative charging degree is
Reached set meal total value, jumps directly to step 10；Such as accumulative charging degree is still not up to set meal total value, go to step 5 after
It is continuous to execute；
BMS starting authentication true form generator in step 5, electric vehicle generates a new authentication true form；
Step 6, authentication true form are sent to charging pile by CAN bus by BMS later by obtaining authentication code after 1 operation of algorithm,
If it is the charging pile of specified services quotient, then the authentication code received can be returned code at authentication according to 2 operation of built-in algorithm by charging pile
After be passed back to BMS；
Step 7, BMS carry out verification judgement according to checking algorithm if receiving authentication and returning code；If do not had within the designated time
It receives authentication and returns code, then show that the charging pile does not meet this agreement or communication failure, jump to step 11；
If step 8, BMS have received response, the authentication received is returned into code and authentication true form, operation is carried out by checking algorithm
Obtain a result；
Step 9, if the result of step 8 operation is some expected definite value, judge that the charging pile meets specified charging service
Quotient's algorithmic rule；10 are thened follow the steps, if do not met, jumps to step 11；
Step 10, electric vehicle execute charging action according to 27930 standard of GB/T；
Step 11, charge condition are not met, and terminate this charging flow.
The invention has the advantages that based on authentication code authentication techniques knee authentication charging system will powerful support fill
Electric service provider carries out marketing activity.Since this charging method has the ability of identification knee mutual authentication and can effectively prevent imitating
It emits, the electric vehicle user for the service that can be enjoyed privileges with operative constraint charges privately except contract range, avoids charging service
While quotient's income is damaged, the threshold that electric vehicle popularizes is greatly reduced by way of preferential service, is facilitated
The development in an all-round way of electric vehicle industrial chain.
