Embodiment
The present invention will be further explained below in conjunction with accompanying drawing.
The configuration of electric automobile charging station system:
As shown in Figure 1, the basic structure composition diagram that has the electric automobile charging station system of energy storage device for the present invention.The electric automobile charging station system that this has energy storage device comprises Alternating Current Power Supply electrical network 1, watch-dog 2, charging device 4 and energy storage device 3; Alternating Current Power Supply electrical network 1 inserts the electric automobile charging station system by high pressure relaying protection cabinet, three-phase transformer and low pressure relaying protection cabinet; Watch-dog 2 is finished the monitoring of electric automobile charging station system and control, instructs the operation of whole electric automobile charging station system; Energy storage device 3 contains some energy storage device groups, and each energy storage device group is made of some on-off controllers and energy storage device; Described charging device 4 contains some charging device groups, and each charging device group is made of some on-off controllers and charging pile.Wherein the selection of energy storage device is particularly important for this.The energy storage device of charging station can adopt super capacitor and lithium titanate battery combination or adopt the lithium titanate battery to constitute energy storage device separately, this mainly be since the lithium titanate cell charging times can reach 20000 times, operating temperature range is wide, charge rate is fast, energy density is higher, though and the super capacitor energy density is not very high, but has very high power density, can adopt high current charge-discharge, the speed that discharges and recharges is fast and pattern is simple, is quick charge truly, long service life.
Generally, the capacity of energy storage device will be much larger than the required energy of single electric automobile, for the better utilization energy, optimize charge efficiency, when configuration has the electric automobile charging station of energy storage device, can be one or a several energy storage device band number charging device, such as five charging electric vehicle equipment of an energy storage device control.
The control method of electric automobile charging station system:
Schematic diagram when as shown in Figure 2, having the normal accumulation of energy charging of the charging station work of energy storage device for employing.Charging station is energy storage device charging accumulation of energy in the low power consumption period generally.Low power consumption is much more general at night, and the quantity of the automobile that charges simultaneously is also less, at this moment between in the section charging station obtain the energy storage device charging accumulation of energy that electric power is given charging station to charge normal speed from electrical network, the energy storage time that generally charges is about 6-8 hour.Watch-dog is mainly monitored information such as electric network information and energy storage device stored energy state.
Belong to peak of power consumption daytime, this moment, charging station mainly was that the electric energy that will store charges for the electric automobile user to electric motor car, and it moves schematic diagram as shown in Figure 4 normally.At this moment, watch-dog is mainly monitored information such as electric network information, energy storage device stored energy residual state, charger operating state.
In addition if the energy storage of charging station has more surplus in certain period, peak of power consumption period by day, under the situation that guarantees the charging station operate as normal, charging station can be realized the energy feedback with by the electrical network demand electric energy of surplus being fed back to grid company.At this moment, energy Flow flows to AC network by energy storage device, and its operation schematic diagram as shown in Figure 3.Charging station still can obtain extra income from the price difference that energy storage device discharges and recharges.At this moment, watch-dog is mainly monitored information such as electric network information and energy storage device energy stored surplus.
When charging station work energy stored can not satisfy electric automobile electricity consumption demand, charging station can directly utilize AC network to give electric automobile with normal speed charging (non-immediate mode charging), to keep charging station normal operation to a certain extent.
The maintenance expansion of electric automobile charging station system:
If the electric automobile of this area increases, charging station just needs dilatation, sets up more energy storage device and charging device and get final product, invest lessly, extends simply.
If certain one or more energy storage device need safeguard or change the time, can be isolated this equipment by the switch that draws back these equipment input and output both sides, and can not have influence on the operate as normal of other equipment, very simple and convenient.
