Abstract

The utility model relates to a charging station that timesharing power matches, including the power and fill electric pile, the power links to each other with charging station distribution device's generating line, and its characterized in that fills electric pile's input and passes through the charging circuit switch and link to each other with the generating line, and the output that fills electric pile links to each other with electric automobile, and the controller that has timesharing power matching function links to each other with the charging circuit switch simultaneously and fills electric pile. The beneficial effects are that: the demand of charging station construction to power capacity is reduced, and the design selection technical requirement of charging pile equipment is reduced. Through timesharing power matching, in certain time quantum, increased the electric automobile quantity of carrying out charging service simultaneously, help alleviating the traffic flow phenomenon of lining up of charging business peak hour, promote the car owner and experience.

Description

Charging station with time-sharing power matching function

Technical Field

The utility model relates to a charging station that time sharing power matches belongs to electric automobile charging control technical field.

Background

With the economic development and the improvement of living standard, the requirement of environmental protection is increasingly highlighted. The electric automobile conforms to the requirement of environmental protection, takes electric energy as power, does not generate waste gas such as carbon dioxide and the like, and is accelerated and popularized in recent years under the encouragement of governments.

Similar to the traditional fuel automobile which refuels to a gas station, the electric automobile needs to be supplemented with electric quantity to a charging station. At present, existing enterprises aim at the prospect of future charging business and build charging stations with a certain scale. When a charging station is built, the problem of large power capacity requirement of the whole charging station is inevitably met. The larger the power supply capacity, the larger the investment in power supply lines, and the power companies in some places also charge capacity fees by capacity. In particular, even if it is desired to increase the line investment, the capacity of peripheral substations or switchgears is insufficient. And power capacity has been little, then when electric automobile peak of charging, can not satisfy all and fill electric pile simultaneous working, has reduced the availability factor of equipment, has influenced car owner's the experience of charging simultaneously.

There is two electric pile that fill on the existing market, can charge for a car or two cars simultaneously. When only one vehicle is charged, the charging power is the rated power of the charging pile; when two vehicles are charged at the same time, the charging power of each charging port is half of the rated power of the charging pile.

In this way, the number of simultaneous charging can be increased at the peak of charging, but there are the following problems:

1. the power supply capacity still needs to be matched according to the power requirement of the whole charging station;

2. the general power of two electric pile of filling is great, and charging station equipment lectotype is limited.

Disclosure of Invention

The utility model aims at providing a charging station that time sharing power matches aims at reducing the investment cost of charging station, optimizes the operation service of charging station.

In order to realize the above purpose, the technical scheme of the utility model a charging station of timesharing power matching is provided, including the power and fill electric pile, the power links to each other with charging station distribution device's generating line, its characterized in that, and the input that fills electric pile passes through the charging circuit switch and links to each other with the generating line, and the output that fills electric pile links to each other with electric automobile, and the controller that has timesharing power matching function simultaneously with the charging circuit switch and fill electric pile and be connected.

The utility model has the advantages that: adopt this controlling means, will reduce the demand of charging station construction to power capacity, reduce the design lectotype technical requirement of filling electric pile equipment. Through timesharing power matching, in certain time quantum, increased the electric automobile quantity of carrying out charging service, help alleviating the traffic flow phenomenon of lining up of charging business peak hour, promote the owner's experience.

1. The demand of charging station construction on power capacity is reduced, and investment construction cost is reduced.

2. The operation of the charging station is optimized, and the service level is improved.

3. Promotes the popularization of electric automobiles and reduces the carbon emission.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model relates to a charging station that time sharing power matches, as shown in figure 1, the power 1 of charging station links to each other with charging station distribution device's generating line 2, and the input that fills electric pile 4 passes through charging circuit switch 3 and links to each other with generating line 2, and the output that fills electric pile 4 links to each other with electric automobile 5, and controller 6 links to each other with charging circuit switch 3 and fill electric pile 4 simultaneously. When the electric automobile 5 joins or exits the use queue of the charging pile 4, the data of the controller 6 is updated correspondingly, and the on-off of the charging loop switch 3 is controlled according to a certain logic program, so that the total charging power at any moment is not more than the capacity provided by the power supply 1.

As shown in fig. 2, p1, p2, … … pn represent the rated power of each charging pile 4 in the current charging sequence, t1, t2, … … tn represent a certain charging time period, a value "1" represents that the corresponding charging pile 4 operates at the rated power in the corresponding time period, and a value "0" represents that the corresponding charging pile 4 stops operating in the corresponding time period. By controlling, at any time,

meanwhile, each charging pile 4 can charge the electric automobile 5 which needs to be charged in the time t 1-tn. If the power supply capacity allows only m electric vehicles 5 to be charged at the same time, a maximum of m charging circuit switches 3 are turned on at the same time. When the number of the electric vehicles needing to be charged is larger than the power supply capacity, all the electric vehicles 5 needing to be charged are charged in turn.

The working flow of the charging control device is shown in fig. 3.
