It connects, charhing unit 5 issues charge request and instructs to EMS Energy Management System 6, and forming charging with EMS Energy Management System 6 allows
Signal is to system control unit, to start generating-charging；If communication is shaken hands unsuccessful, manual operation is continued waiting for or turned.
Charhing unit 5 carries out communicating identification of shaking hands according to the solicited message that electric car BMS administrative unit is sent, and will be electric
The identification information of electrical automobile is transferred in EMS Energy Management System 6.6 pairs of the EMS Energy Management System electric cars connected are known
Other information carries out knowledge method for distinguishing: EMS Energy Management System 6 by the information identified with prestore the pre- of EMS Energy Management System 6
Determine information to be compared, if identification information matches with predetermined information, determines to identify successfully；If identification information and predetermined information
It mismatches, then determines recognition failures.
Step S2, starting power generation, charge condition confirmation, start to charge benefit electricity: system control unit receives EMS energy management
After the charge permission signal that system 6 issues, 42 are opened the safety-valve, provide generator enabling signal and start gas electricity generator 2, be
After system control unit checks that voltage, the frequency signal that gas electricity generator 2 exports reach setting value, inversion is issued to charhing unit 5
Output services requirement, 5 inversion of charhing unit simultaneously export electric energy to the batteries of electric automobile being electrically charged, start to charge benefit electricity；It is related
Charging status signal is fed back simultaneously arrives EMS Energy Management System 6, is shown and is monitored.
If the AC charging that EMS Energy Management System 6 receives communication unit inputs desired signal, pass through ac bus AC
Output interface charges and monitors in real time to electric car；If received EMS Energy Management System 6 is DC charging input demand letter
Number, then it charges and monitors in real time to electric car by DC bus DC output interface.
Step S3, generating-charging process, system capacity match timing monitoring: 2 normal power generation of gas electricity generator, the friendship of output
Galvanic electricity charges through exchange output bus, AC/DC converting unit, direct current output bus, charging gun 51 to electric car, EMS
Energy Management System 6 and electric car BMS administrative unit detects power generation, inversion, charge data respectively and is monitored, according to hair
Electricity, charge parameter simultaneously carry out timing monitoring and adjust, and the charging to electric car is completed by the charging curve of setting.
The working condition that EMS Energy Management System 6 is exported according to gas electricity generator 2 simultaneously, control carry out super capacitor
Electric discharge or charging provide big energy in short-term in the starting transient process stage of gas electricity generator 2 for the charging of electric car fast charge, are used for
It makes up and stablizes that 2 capacity of gas electricity generator is limited or the energy supply of the processes such as transition.Electric car electric energy demand reduce or
Into during equalizaing charge, charged in time to super capacitor using 2 power surplus of gas electricity generator, in case standby starting next time,
Make that the gas electricity generator 2 of movable integral natural gas charger is more steady, electric energy preferably optimizes use.
Step S31: more electric cars are simultaneously or the realization successively charged: in the process if any new electric car m
It needs to charge simultaneously, after the charging that insertion charging gun 51m completes above-mentioned steps S1 is shaken hands and is identified normally, EMS energy pipe
Reason system 6 and control generating and charging system are directly entered step S3, start to new electric car m while carrying out charging benefit electricity,
EMS Energy Management System 6 carries out energy point according to the charge requirement that the power generation capacity and Liang Tai of generator are electrically charged electric car
With with optimization and timing monitoring.It needs while charging if any new electric car n, in insertion charging gun 51n
Ground carries out control execution.
Step S4, charging complete stop charging, release charging communication and shake hands, release charging physical connection: being electrically charged electronic
Automobile charge volume is full or sending is forced to stop charging to mend electric instruction, and EMS Energy Management System 6 receives stopping charging benefit electric signal simultaneously
It is issued to system control unit and stops charging instruction, charhing unit 5 stops rechargeable electrical energy output, charhing unit 5 and electric car
BMS administrative unit releases communication and shakes hands, and EMS Energy Management System 6 records and stores related data, and charging gun 51 can pull away electronic
Automobile charging interface releases physical connection.
Step S41, EMS Energy Management System 6 detects whether that there are also 51 interfaces of charging gun to carry out charging benefit electricity work, such as
There is charging gun 51m, n continuing to charge, repeat step S4 and so on ground stop the charging of each charging interface, it is standby into charging
State.
Step S5, confirmation stop inversion and power generation, standby: EMS Energy Management System 6 confirms all fill without charge requirement
It after electrical interface mends the work and demand of electricity energy supply without charging, issues and instructs to system control unit, AC/DC converting unit stops work
To make, charhing unit 5 stops inversion, and gas electricity generator 2 is out of service, closed safe valve 42, a generating-charging job is completed, to
Machine enters step S0 waiting, and generating-charging instructs next time, or disconnection protective switch 8 is standby.
