Description
Technical field
The present invention relates to charging electric vehicle field, more particularly to it is a kind of can smooth expansion direct-current charging post realization side
Method.
Background technology
Herein in recent years, because the energy is largely consumed, cause environmental pollution also increasingly serious.Now, in order to set up saving
Type society, use of the people to electric automobile is also more and more universal.Electric automobile replaces fuel oil with electric power, with environmental protection, energy-conservation,
Light, low noise advantages, therefore, it is possible to solve the problems, such as energy crisis and environmental pollution to a certain extent.Meanwhile, as
The demand of the charging pile of the hardware auxiliary facility of electric vehicle is also increasing, and the development of electric automobile be unable to do without conveniently
The construction and development of charging pile.But, with the increasingly popularization of electric automobile, the charging problems of electric automobile become increasingly conspicuous.
Charging pile is divided into two kinds, and one kind is alternating-current charging pile, and one kind is direct-current charging post.Alternating-current charging pile output 220V's
Alternating current charges a battery by Vehicular charger.Direct-current charging post can export high-voltage great-current and be filled directly to battery
Electricity.The direct-current charging post charging interval is than alternating-current charging pile charging interval much shorter.Therefore, direct-current charging post obtains many users
Welcome.
In current direct-current charging post technical scheme, at the initial stage that direct-current charging post is built, because the automobile amount applied is few,
The power of charging electric vehicle requirement is small, so the power of the direct-current charging post built is also smaller.But follow-up automobile has more rapidly
The demand of charging, such as require the high-power charging of 120KW, and the charging pile of the 60KW that early stage can only be now built is removed, weight
The new charging pile for building 120KW, this is not only greatly increased builds a workload, while also result in the wasting of resources.
The content of the invention
The present invention is carried out to solve problem present in above-mentioned background technology, it is therefore intended that providing one kind can put down
The implementation method of the direct-current charging post of sliding dilatation.

7. it is according to claim 1 it is a kind of can smooth expansion direct-current charging post implementation method, it is characterised in that：Direct current
Communication process between the control module of charging pile is as follows：
1) control module of direct-current charging post 1 detects the electric automobile connected on DC charging rifle 1 and needs more than Power1
Power P WA, the control module of direct-current charging post 1 is sent to the performance number PWA-Power1 control module of direct-current charging post 2；
2) whether other electric automobiles for needing to charge are connected with the control module detection direct-current charging post 2 of direct-current charging post 2,
And the information transmission for detecting to direct-current charging post 1 control module；If needing to charge without other electric automobiles, direct current
The control module of charging pile 1 is closed by controlling high-voltage relay AK and high-voltage relay to switch AK-1, the control of direct-current charging post 2
Molding block is disconnected by controlling the high-voltage relay AK of direct-current charging post 2, and the power of direct-current charging post 2 is superimposed to direct current on demand
Charging pile 1；If other electric automobiles need to charge, the control module of direct-current charging post 1 is by controlling high-voltage relay AK
Closure, high-voltage relay switch AK-1 disconnect, the control module of direct-current charging post 2 by control the high pressure of direct-current charging post 2 after
Electrical equipment AK is closed, and is only charged to the electric automobile being connected on direct-current charging post 2, is no longer superimposed other direct-current charging posts and is arrived
Direct-current charging post 1；
3) after the power of direct-current charging post 2 is superimposed to direct-current charging post 1, the control module of direct-current charging post 1 is detected, works as control
Even if the power P ower2 that molding block is detected plus direct-current charging post 2 still can not meet the power need of the electric automobile of connection
When asking, the control module of direct-current charging post 1 is sent to the performance number PWA-Power1-Power2 control of direct-current charging post 3
Module；
4) whether other electronic vapour for needing to charge are connected with the control module detection direct-current charging post 3 of direct-current charging post 3
Car, and the information transmission for detecting to direct-current charging post 2 control module；If needing to charge without other electric automobiles,
The control module of direct-current charging post 2 is closed by controlling high-voltage relay to switch AK-2, and the control module of direct-current charging post 3 passes through
Control the high-voltage relay AK of direct-current charging post 3 to disconnect, the power of direct-current charging post 3 is superimposed to direct-current charging post 2 on demand, enter
One step is added to direct-current charging post 1；If other electric automobiles need to charge, the control module of direct-current charging post 2 is by control
High-voltage relay processed switch AK-2 disconnects, and the control module of direct-current charging post 3 is by controlling the high-voltage relay of direct-current charging post 3
AK is closed, and is only charged to the electric automobile being connected on direct-current charging post 3, is no longer superimposed other direct-current charging posts to direct current
Charging pile 1；
5) the rest may be inferred, realize direct-current charging post 2, direct-current charging post 3 ..., the power of direct-current charging post N is sequentially overlaid on directly
Current charge stake 1；Conversely, can direct-current charging post 1, direct-current charging post 2 ..., direct-current charging post N-1 power is superimposed to straight on demand
Current charge stake N.
