Further, in the present embodiment, the charging equipment setting current start value and current upper limit value, it is described to fill The charging current of electric equipment can be regulated and controled between the current start value and the current upper limit value, that is, increased or downgraded. Specifically, in the present embodiment, the current start value is 6A, and the current upper limit value is 32A.It is appreciated that when described When the charging current of charging equipment is less than the current start value, the charging equipment cannot then start charge function.

Further, user, can be first by the quasi- charging equipment and the vehicle when needing to charge to vehicle Charging connection is carried out, then the quasi- charging equipment is opened by barcode scanning or the modes such as swipe the card.It is appreciated that described in being opened as user After quasi- charging equipment, charge requirement is sent to the charge requirement acquiring unit 310 by the quasi- charging equipment, and the charging needs Ask acquiring unit 310 that can get the charge requirement of the quasi- charging equipment.

Further, the charge requirement acquiring unit 310 sends out the charge requirement after receiving the charge requirement The analytical unit 330 is given, the analytical unit 330 obtains the quasi- charging equipment institute by the power acquisition unit 10 The charging current of other all charging equipments in phase line, and calculate the quasi- charging current.

Further, the number information of all charging equipments in the phase line is stored in the analytical unit 330, it is described The number information of charging equipment in the phase line is sent to the power acquisition unit 10 and passes through the electricity by analytical unit 330 Power acquiring unit 10 gets the charging current of the corresponding charging equipment.

Further, after the analytical unit 330 receives the charging current, by the charging current of the charging equipment Superposition calculates the current idle current of the phase line and/or can to obtain current the first real-time electric power load of the phase line Use electric current.

Further, in the present embodiment, the idle current be the phase line in the first electric current downgrade threshold value with The difference of the first real-time electric power load.If being appreciated that, first current threshold is 200A, first real-time electric power Load is 180A, then the idle current is 20A.

Further, in the present embodiment, the available current is the sum of the idle current and electric current adjusted value.Into One step, the electric current adjusted value is the sum of the adjustable electric flow valuve of all charging equipments in the phase line, described adjustable Current value is the charging current of the charging equipment and the difference of current start value.Further, it is needed when calculating the available current The adjustable electric flow valuve of each charging equipment in the phase line is first calculated, then is superimposed the adjustable electric flow valuve to obtain the electricity Adjusted value is flowed, then the available current is gone out by the electric current adjustment calculation.It is appreciated that if currently owning in the phase line The quantity of charging equipment is 3, respectively charging equipment A, charging equipment B and charging equipment C, the charging current of charging equipment A For 9A, the charging current of charging equipment B is 11A, and the charging current of charging equipment C is 12A, and current start value is 6A, idle electricity Stream is 20A, then the adjustable electric flow valuve of the charging equipment A is 9A-6A=3A, and the adjustable electric flow valuve of the charging equipment B is 11A- The adjustable electric flow valuve of 6A=5A, the charging equipment C are 12A-6A=6A, then the electric current adjusted value is 3A+5A+6A=14A, institute Stating available current is 20A+14A=34A.

Further, in the present embodiment, the analytical unit 330 is less than the current start in the available current When value, show that the quasi- charging current is zero.Specifically, such as the analytical unit 330 is when the available current is 4A, by The current start value described in present embodiment is 6A, then the available current is less than the current start value, illustrates institute at this time State the charge function that the available current in phase line is not enough to start the quasi- charging equipment.In other words, guaranteeing the phase at this time It is filled even if the first real-time electric power load of line is no more than in the case that first electric current downgrades threshold value by all in the phase line Available current of the charging current of electric equipment when adjusting to 6A in the phase line is only 4A, is set at this time to start the quasi- charging Standby charge function, it will so that the charging current electric current of the phase line inner part charging equipment downgrades value 6A hereinafter, leading in turn It causes the charging current of charging equipment in the phase line to be less than the current start value and then closes, influence described in the phase line fill Electric equipment charges normal.Therefore, the analytical unit 330 is not permitted when the available current is less than the current start value Perhaps start the charge function of the quasi- charging equipment, therefore show that the quasi- charging current is zero.

Further, described control unit 350 is when receiving the quasi- charging current is zero, will not start described quasi- fill The charge function of electric equipment.Further, reservation charging sequence is added in the quasi- charging equipment by described control unit 350, When the available current is not less than the current start value, restart the charge function of the quasi- charging equipment.

Further, in the present embodiment, the analytical unit 330 is opened in the available current not less than the electric current Dynamic value, and when the idle current is less than the current start value, show that the quasi- charging current is that the first electric current downgrades threshold value With the ratio of charging equipment total quantity, the charging equipment total quantity is the quantity of the charging equipment in the phase line and described quasi- The sum of charging quantity of charging equipment.Specifically, for example, the analytical unit 330 the available current be 16A, the free time When electric current is 4A, the current start value as described in present embodiment is 6A, and the idle current is less than the electric current and opens It moves value and the available current is not less than the current start value, illustrate that idle current at this time is not enough to start the quasi- charging The charge function of equipment but can deploy the charging currents of other charging equipments phase line Nei to the quasi- charging equipment to Start the charge function of the quasi- charging equipment.In other words, do not surpass in the first real-time electric power load for guaranteeing the phase line at this time Crossing in the case that first electric current downgrades threshold value can reassign to all electric currents of the phase line in the phase line Charging equipment and the quasi- charging equipment are to guarantee the charging function of the charging equipment and the quasi- charging equipment in the phase line Can, therefore show that the quasi- charging current is the ratio that first electric current downgrades threshold value Yu the charging equipment total quantity.Tool Body, such as the quantity of the charging equipment in the phase line is 3, described first to downgrade threshold value be 80A, the quasi- charging equipment Quantity be 1, then the total quantity of the charging equipment be 3+1=4, the quasi- charging current be 80A/4=20A.Also that is, it is described Analytical unit 330 is not less than the current start value in the available current, and the idle current is less than the current start When value, first the quantity of all charging equipments in the phase line is added to obtain charging equipment with the quantity of the quasi- charging equipment Total quantity, and first electric current is downgraded into charging equipment in the current value mean allocation to the phase line of threshold value and described quasi- Charging equipment is so as to meeting the charge requirement of charging equipment and the quasi- charging equipment in the phase line.Further, Since first electric current to be downgraded to charging equipment and the quasi- charging in the current value mean allocation to the phase line of threshold value Equipment avoids triggering the electricity so that the first real-time electric power load of the phase line is no more than first electric current and downgrades threshold value The charging of power regulator control system 100 regulates and controls.

Further, described control unit 350 is that first electric current downgrades threshold value receiving the quasi- charging current When with the ratio of the charging equipment total quantity, the charge function for starting the quasi- charging equipment, which simultaneously controls in the phase line, to be owned Charging equipment and the quasi- charging equipment charge according to the quasi- charging current or the current upper limit value.Further Ground if the quasi- charging current is greater than 32A, that is, is greater than the current upper limit value, then institute since the current upper limit value is 32A The quasi- charging current cannot be exported by stating charging equipment, and described control unit 350 controls charging all in the phase line at this time Equipment and the quasi- charging equipment charge according to the current upper limit value；If the quasi- charging current is not more than 32A, i.e., not Greater than the current upper limit value, then the quasi- charging current is less than the current upper limit value, and the charging equipment can export The quasi- charging current, described control unit 350 controls charging equipment all in the phase line at this time and the quasi- charging is set It is standby to charge according to the quasi- charging current.

Further, in the present embodiment, the analytical unit 330 is opened in the idle current not less than the electric current When moving value and being less than current upper limit value, show that the quasi- charging current is the current start value.Specifically, such as the analysis For unit 330 when the idle current is 10A, the current start value as described in present embodiment is 6A, the upper current limit Value is 32A, therefore the idle current not less than the current start value and is less than the current upper limit value 32A, illustrates current Idle current be sufficiently great to initiate the charge function of the quasi- charging equipment but insufficient for the quasi- charging equipment with the electricity Stream upper limit value charges, therefore only needs to guarantee that the charging current can satisfy the charge requirement of the quasi- charging equipment i.e. Can, the analytical unit 330 show that the quasi- charging current is the current start value at this time.

Further, described control unit 350 starts described quasi- when the quasi- charging current is the current start value The charge function of charging equipment simultaneously controls the quasi- charging equipment and charges according to the current start value.It is appreciated that this In the case of kind, charging current of the described control unit 350 without regulating and controlling other charging equipments in the phase line, it is only necessary to described in starting The charge function of quasi- charging equipment is simultaneously charged according to the current start value control quasi- charging equipment.

Further, in the present embodiment, the analytical unit 330 is not less than the electric current in the idle current When upper limit value, show that the quasi- charging current is the current upper limit value.Specifically, the analytical unit 360 is in the free time When electric current is 33A, the current upper limit value as described in present embodiment is 32A, and the idle current is greater than the upper current limit Value, illustrates that current idle current is sufficiently great to initiate the charge function of the quasi- charging equipment, and can allow for the quasi- charging Equipment is charged with current upper limit value, and the analytical unit 330 show that the quasi- charging current is the upper current limit at this time Value.

Further, described control unit 350 starts described quasi- when the quasi- charging current is the current upper limit value The charge function of charging equipment simultaneously controls the quasi- charging equipment and charges according to the current upper limit value.It is appreciated that this In the case of kind, charging current of the described control unit 350 without regulating and controlling other charging equipments in the phase line, it is only necessary to described in starting The charge function of quasi- charging equipment is simultaneously charged according to the current upper limit value control charging equipment.

It is appreciated that the analytical unit 330 is required to according in the phase line when one quasi- charging equipment of every access First real-time electric power load and first available power calculate the quasi- charging current, thus guarantee do not trigger it is described Meet the charge requirement of the quasi- charging equipment in the case where the charging regulation of power regulation system 100.

Charge control system of the invention can obtain the charge requirement of user, and according to the available power of current phase line and Can free power analyze the charge requirement that meet the quasi- charging equipment, and calculates the quasi- charging current, thus described Phase line electric power starts the charge function of the quasi- charging equipment in the range of allowing, ensure that flexibility and the Charge Management of charging Intelligence.

Referring to FIG. 5, four embodiment of the invention provides a kind of charging method, the charging method is applied to aforementioned fill Arrangement, the combination of any embodiment or embodiment of electric control system, comprising the following steps:

Step S410: the charge requirement of the quasi- charging equipment accessed in phase line is obtained.

Further, in the present embodiment, due to being provided with for the phase line in the power regulation system 100 One electric current downgrades threshold value, thus when the quasi- charging equipment newly accessed in the phase line need from the phase line middle acquisition electric current into Row charging, therefore will lead to the load of the first real-time electric power in the phase line and increase, in the first real-time electric power load continuous Increase phase line, circuit or the transformation that 100 pairs of power regulation system generation current overloads will be triggered when there is current overload The charging of charging equipment in device regulates and controls, to downgrade the charging current of other charging equipments, influences other chargings The charge efficiency of equipment, therefore when newly accessing the quasi- charging equipment in the phase line, need first according to the phase line Electric current downgrades threshold value and carries out charge control to the quasi- charging equipment in the electric power for not triggering the power regulation system 100 Guarantee that the charging equipment of the new access can charge normal in the case where regulation as far as possible.

Further, user, can be first by the quasi- charging equipment and the vehicle when needing to charge to vehicle Charging connection is carried out, then the quasi- charging equipment is opened by barcode scanning or the modes such as swipe the card.It is appreciated that described in being opened as user After quasi- charging equipment, the charge requirement of the quasi- charging equipment can be got.

Step S420: computation-free electric current and/or available current, and according to the idle current and/or it is described can electricity consumption Stream obtains quasi- charging current.

Further, it after the charge requirement for getting the quasi- charging equipment, needs further to obtain the quasi- charging and sets The charging current of other all charging equipments in standby place phase line, and calculate the quasi- charging current.

Further, when obtaining the charging current of other all charging equipments, first by charging equipment in the phase line The power acquisition unit 10 that is sent in the power regulation system 100 of number information to get the corresponding charging The charging current of equipment.

Further, after the charging current for receiving the charging equipment, the charging current of the charging equipment is superimposed To obtain current the first real-time electric power load of the phase line, and calculate the current idle current of the phase line and/or can electricity consumption Stream.

Further, in the present embodiment, it when the available current is less than the current start value, obtains described quasi- Charging current is zero.Specifically, when the available current is 4A, the current start value as described in present embodiment is 6A, Then the available current is less than the current start value, and it is described quasi- to illustrate that the available current in the phase line at this time is not enough to start The charge function of charging equipment.In other words, it is no more than described first in the first real-time electric power load for guaranteeing the phase line at this time Even if electric current downgrades phase line when adjusting the charging current of all charging equipments in the phase line to 6A in the case where threshold value Interior available current is only 4A, at this time to the charge function of the starting quasi- charging equipment, it will so that inside the phase line The charging current electric current of charging equipment is divided to downgrade value 6A hereinafter, the charging current of charging equipment in the phase line is caused to be less than in turn It the current start value and then closes, influences charging normal for the charging equipment in the phase line.Therefore, it is described can electricity consumption When stream is less than the current start value, do not allow to start the charge function of the quasi- charging equipment, therefore obtain the quasi- charging Electric current is zero.

When the available current is less than the current start value, illustrate even if by the electric current of the charging equipment of all chargings When downgrading the current start value, the available current in the phase line cannot still reach the current start of the charging equipment Value, thus to starting initiate charge requirement charging equipment charge function, it will cause in the phase line first in real time Electrical load is more than that first electric current downgrades threshold value, and then triggers the charging regulation of the power regulation system 100, to adjust The charging current for dropping all charging equipments in the phase line causes the charging current of part charging equipment lower than the current start Value influences the charging of other users to close.

Further, in the present embodiment, the analytical unit 330 is opened in the available current not less than the electric current When dynamic value, and when the idle current is less than the current start value, show that the quasi- charging current is that the first electric current downgrades threshold The ratio of value and charging equipment total quantity, quantity and institute of the charging equipment total quantity for all charging equipments in the phase line State the sum of the quantity of quasi- charging equipment.Specifically, such as when the available current is 16A, and the idle current is 4A, due to Current start value described in present embodiment be 6A, therefore the idle current be less than the current start value and it is described can electricity consumption Stream is not less than the current start value, the idle current for illustrating at this time be not enough to start the charge function of the quasi- charging equipment but The charging current that other charging equipments phase line Nei can be deployed is set to the quasi- charging equipment to start the quasi- charging Standby charge function.In other words, it is no more than the first electric current tune in the first real-time electric power load for guaranteeing the phase line at this time All electric currents of the phase line can be reassigned to charging equipment in the phase line and described quasi- in the case where drop threshold value Charging equipment obtains described quasi- to guarantee the charge function of charging equipment and the quasi- charging equipment in the phase line Charging current is the ratio that the first electric current downgrades threshold value Yu charging equipment total quantity.Specifically, such as at this time in the phase line The quantity of charging equipment is 3, and described first downgrades threshold value as 80A, and the quantity of the quasi- charging equipment is 1, then described to fill The sum of electric equipment is 3+1=4, and the quasi- charging current is 80A/4=20A.Also that is, being not less than the electricity in the available current Flow initiation value, and the idle current be less than the current start value when, first by the quantity of all charging equipments in the phase line It is added to obtain the total quantity of charging equipment with the quantity of the quasi- charging equipment, and first electric current is downgraded to the electric current of threshold value Charging equipment and the quasi- charging equipment in value mean allocation to the phase line are so as to meeting the charging in the phase line The charge requirement of equipment and the quasi- charging equipment.Further, since the current value that first electric current is downgraded threshold value is put down The charging equipment and the quasi- charging equipment being respectively assigned in the phase line, so that the first real-time electric power load of the phase line is not Threshold value is downgraded more than first electric current, avoids the charging regulation for triggering the power regulation system 100.Further, at this In embodiment, when the idle current is not less than the current start value and is less than current upper limit value, described quasi- fill is obtained Electric current is the current start value.Specifically, when the idle current is 10A, the electric current as described in present embodiment Initiation value is 6A, and the current upper limit value is 32A, therefore the idle current not less than the current start value and is less than described Current upper limit value 32A, illustrate current idle current be sufficiently great to initiate the charge function of the quasi- charging equipment but insufficient for The quasi- charging equipment is charged with the current upper limit value, therefore only needs to guarantee that the charging current can satisfy described intend The charge requirement of charging equipment show that the quasi- charging current is the current start value at this time.

Further, in the present embodiment, when the idle current is not less than the current upper limit value, illustrate current Idle current be sufficiently great to initiate the charge function of the quasi- charging equipment, and can allow for the quasi- charging equipment on electric current Limit value charges, and show that the quasi- charging current is the current upper limit value at this time.Specifically, it is in the idle current When 33A, the current upper limit value as described in present embodiment is 32A, and the idle current is greater than the current upper limit value, explanation Current idle current is sufficiently great to initiate the charge function of the quasi- charging equipment, and can allow for the quasi- charging equipment with institute It states current upper limit value to charge, show that the quasi- charging current is the current upper limit value at this time.

Step S430: start or close the charge function of the quasi- charging equipment according to the quasi- charging current.

Further, after receiving the quasi- charging current, the quasi- charging can be controlled according to the quasi- charging current Whether equipment starts charging.

Further, in the present embodiment, when the quasi- charging current is zero, the quasi- charging current is being received When being zero, the charge function of the quasi- charging equipment will not started.Further, reservation charging is added in the quasi- charging equipment Sequence restarts the charge function of the quasi- charging equipment when the available current is not less than the current start value.

It further, in the present embodiment, is that first electric current downgrades threshold value receiving the quasi- charging current When with the ratio of the charging equipment total quantity, the charge function for starting the quasi- charging equipment, which simultaneously controls in the phase line, to be owned Charging equipment and the quasi- charging equipment charge according to the quasi- charging current or the current upper limit value.Further Ground if the quasi- charging current is greater than 32A, that is, is greater than the current upper limit value, then institute since the current upper limit value is 32A The quasi- charging current cannot be exported by stating charging equipment, control charging equipment all in the phase line and the quasi- charging at this time Equipment charges according to the current upper limit value；If the quasi- charging current is not more than 32A, that is, it is not more than the upper current limit Value, then the quasi- charging current is less than the current upper limit value, and the charging equipment can export the quasi- charging current, this When described control unit 350 control charging equipment all in the phase line and the quasi- charging equipment according to the quasi- charging electricity Stream charges.
