The utility model can be arranged as required to law of electric charges, can be existing law of electric charges.The present embodiment opens public affairs
A kind of law of electric charges is opened：Customer selecting urgency mold filling formula and intelligent mold filling formula, the charging electricity price for setting anxious mold filling formula is allowed to be higher than
The charging electricity price of intelligent mold filling formula, taiwan area central control unit distribute electric power resource in the electric automobile to the anxious mold filling formula of request
Afterwards, just by dump power resource allocation to the electric automobile for asking intelligent mold filling formula；If customer selecting is anxious mold filling formula,
On the premise of taiwan area transformer capacity surplus, it is allowed to which sufficient amount of charging pile suddenly fills the sequencing of order by receiving
To ask the electric automobile of anxious mold filling formula to be charged, until the electric quantity of batteries of electric vehicle for asking anxious mold filling formula is full of or visitor
Householder is dynamic to stop charging；If customer selecting is intelligent mold filling formula, on the premise of without departing from taiwan area transformer capacity surplus, permit
Perhaps sufficient amount of charging pile presses the order of automobile battery power from low to high to ask the electric automobile of intelligent mold filling formula to enter
Row charging, until electric quantity of batteries of electric vehicle be full of or client actively stop charging.Anxious mold filling formula is used to meet to be badly in need of as electricity
The client of electrical automobile charging.
Taiwan area central control unit is from the battery level information of the electric automobile of the intelligent mold filling formula of request of acquisition, by electricity
The order of pond electricity from low to high, selection ask the electric automobile of intelligent mold filling formula to be charged, when encountering a certain battery electric quantity
Some electric automobiles of position correspondence, if current residual allows to carry out the slow electric automobile quantity filled and is more than or equal to the battery electric quantity
The quantity of the electric automobile of position correspondence, the then whole electric automobiles for choosing the battery electric quantity position correspondence are charged, if working as
Preceding residue allows the quantity for carrying out the electric automobile that the slow electric automobile quantity filled is less than the battery electric quantity position correspondence, then from this
The electric automobile that requirement is randomly selected in the electric automobile of battery electric quantity position correspondence is charged.
Such as：Allow 12 charging piles to be charged assuming that working as foreground partition transformer capacity surplus, there are 17 electric automobiles
Need to charge.Wherein there are 2 electric automobiles for being badly in need of charging to select anxious mold filling formula.So remaining 15 electric automobiles can only have
Ten can carry out slow fill.In this 15 electric automobiles, the electric automobile of remaining 15%, 20%, 25% electricity has 5 respectively.According to
Intelligence fills pattern rules, the electric automobile 5 of remaining 15% electricity, and quantity, which is less than, to be allowed to carry out the slow alternating-current charging pile quantity filled
10,5 can all charge.The electric automobile 5 of remaining 20% electricity, quantity are equal to residue and allow to carry out the slow exchange filled
Charging pile quantity 5, this 5 electric automobiles can all charge.5 electric automobiles of remaining 25% electricity etc..Assuming that charging one
After the section time, this 10 electric automobiles have all filled 5% electricity.Now, the electric automobile of remaining 20% electricity has 5, residue 25%
The electric automobile of electricity has 10.Pattern rules are filled according to intelligence, the electric automobile 5 of remaining 20% electricity, quantity, which is less than, to be allowed
The slow alternating-current charging pile quantity filled is carried out, 5 can all charge.The electric automobile of dump energy 25% has 10, and quantity is more than
Residue allows to carry out the slow alternating-current charging pile quantity 5 filled, and is charged so randomly choosing 5 from 10 electric automobiles.
So move in circles, until electric automobile electricity be full of or client actively stop charging.
If wherein there are 12 electric automobiles for being badly in need of charging to select anxious mold filling formula.Then it is badly in need of the electric automobiles to charge all for 12
Charged.If wherein there is 17 electric automobiles for being badly in need of charging to select anxious mold filling formulas, according to receiving the anxious priority for filling order
The electric automobiles that sequential selection 12 is badly in need of charging are charged, until electric automobile electricity is full of or client actively stops filling
Electricity.
Charging pile charging price uses floating price, designs two grades of charging prices, respectively anxious mold filling again on this basis
Formula charging price and intelligent mold filling formula charging price, anxious mold filling formula charging price is higher than intelligent mold filling formula charging price.
1）Floating price
There is spike Pinggu phase in supply network, it is low that the electricity rates of different periods also have height to have.So filled in design communication
During electric stake charging price, also referring to being designed based on the electricity price of power supply network spike Pinggu phase, alternating-current charging pile urgency mold filling formula
Charging price with intelligent mold filling formula is also not stop change.Its object is to utilize price factor peak load shifting, electricity is reduced
Net burden, keep power supply steady.
2）Anxious mold filling formula charging price
Anxious mold filling formula charging price increases on the basis of floating price, and corresponding intelligent mold filling formula charging price will height.
This is to meet customer demand that especially needs are charged to electric automobile, but simultaneously as is preferentially occupied
Charging power resource, so price can have been lifted.This is also to meet outside client's urgent need demand, encourages people to use intelligent mold filling
Formula, as far as possible mean allocation charging power resource.
3）Intelligent mold filling formula charging price
Intelligent mold filling formula charging price increases on the basis of floating price, low to emergent mold filling formula charging price.
Intelligent mold filling formula can be more average distribution charging power resource, also because do not possess in charging power resource
Priority, the reason for charging electric vehicle time relatively anxious mold filling formula is long, so charging price is lower than anxious mold filling formula charging price.
Simultaneously and pass through price factor, encourage the not anxious client for filling demand to be charged as far as possible using intelligent mold filling formula.
