In an embodiment of the present invention, described user VIP preference strategy is: system control unit judges whether system has dump power to distribute to vehicle to be filled, if system does not have dump power to distribute, then the charge power of current charging vehicle is dropped to 50% of system power by system control unit, and adjustment phase inductive charging module is to Vehicular charging to be filled; If there is dump power to distribute, then judge whether single charging module meets Vehicular charging power demand to be filled by system control unit, if meet charge requirement, then system control unit starts phase inductive charging module to Vehicular charging to be filled, if do not meet charge requirement, then system control unit adjusts one group or the two groups modules that charge to Vehicular charging to be filled according to dump power situation.User VIP preference strategy particular flow sheet is see Fig. 6.
In a specific embodiment of the present invention,
1) when only having a car to charge, charge power demand as current charging vehicle is less than or equal to the power output of single charging module, then system only gives current charging vehicle the charging module power division corresponding with this charging inlet, such as current charging vehicle uses charging inlet 1 to charge, then the power of charging module 1 outputs to charging inlet 1 by switch element 1, another group charging module power does not then export, simultaneously cut-off switch unit 2 and auxiliary switching element, the system charge power that namely system only distributes 50% just can meet the charge requirement of current charging vehicle;
2) if when the charge power demand of current charging vehicle is greater than the power of single group charging module, then the dynamic two groups of charging module power of system assignment give current charging vehicle, such as by Closing Switch unit 1 and switch element 2, the power of charging module 1 and charging module 2 is all outputted to charging inlet 1, and namely the system charge power of system assignment 100% gives current charging vehicle.
3) if now vehicle to be filled needs charging, as current charging vehicle only uses the system charge power of 50%, then the charge power of remaining 50% is distributed to vehicle to be filled by system, Systematical control charging module 2 starts, Closing Switch unit 2, by the power stage of charging module 2 to charging inlet 2, namely system assignment is also 50% of system charge power to the power of vehicle to be filled.
4) as system can distribute to Vehicular charging to be filled without dump power, the then user gradation of the more current charging vehicle of system control unit and vehicle to be filled, if current charging vehicle is identical with vehicle user grade to be filled, namely domestic consumer or VIP user is all, then after filling vehicle and need waiting for that the charge power of current charging vehicle charging charging complete or current charging vehicle drops to the system charge power being less than or equal to 50%, vehicle to be filled could obtain charge power:
After the charging of a, current charging vehicle is full, system cut-off switch unit 1, auxiliary switching element, if Vehicular charging power demand to be filled is for being less than or equal to system charge power 50%, then system Closing Switch unit 2, starts charging module 2 to Vehicular charging to be filled; If Vehicular charging power demand to be filled is greater than 50%, then Closing Switch unit 2, auxiliary switching element, switch element 1 disconnects, and starts charging module 1 with charging module 2 to Vehicular charging to be filled.
B, the slump in demand of current charging vehicle charge power to be less than or equal to system charge power 50% time, vehicle to be filled also can be assigned to charge power, now Systematical control auxiliary switching element disconnects, Closing Switch unit 2, maintained switch unit 1 closes, and the charge power namely distributing to current charging vehicle and vehicle to be filled is 50% of system charge power.
5) current charging vehicle is not identical with the user gradation of vehicle to be filled, if current charging vehicle is VIP user, vehicle to be filled is domestic consumer, and system can for when distributing without dump power, wait fill vehicle need wait for current charging vehicle charging terminate or wait for current charging vehicle charge power be reduced to be less than or equal to system charge power 50% after, system has dump power can supply to distribute, and vehicle to be filled could start charging.
6) current charging vehicle is not identical with the user gradation of vehicle to be filled, current charging vehicle is domestic consumer, vehicle to be filled is VIP user, and now system can be distributed without dump power, because vehicle rank to be filled is higher than current charging vehicle rank, vehicle to be filled has authority of preferentially charging, therefore Systematical control auxiliary switching element disconnection, Closing Switch unit 2, start charging module 2 to Vehicular charging to be filled, and maintained switch unit 1 closes, namely system assignment is 50% of system charge power to the charge power of current charging vehicle and vehicle to be filled.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
