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, 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, 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.
