Further, wherein, the step(6)In, the charging module quantity for calculating needs distribution is specially:Need The output current of charging module quantity=maximum charging current/single charging module of distribution.
Compared with existing charging method, the multiple gun charger charging method that power output of the invention is distributed automatically on demand And charger has following advantageous effects:It can be controlled in charging and rifle is carried out to which using which charging module Charging, therefore, it is possible to automatically adjust charging power output according to user's charging needs, and multiple charging guns can share charging Module resource, effectively prevent charging resources idle, and automobile can be made to be charged in most fast mode.
Brief description of the drawings
Fig. 1 is the composition schematic diagram of the charger of the present invention.
Fig. 2 is the flow chart for the multiple gun charger charging method that power output of the invention is distributed automatically on demand.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples, and the content of embodiment is not as the guarantor to the present invention Protect the limitation of scope.
Fig. 1 shows the composition schematic diagram of the charger of the present invention.As shown in figure 1, the charger of the present invention includes resource Dispensing controller.The resource allocation controller is used for the management for realizing charging resource.
Wherein, the resource allocation controller is connected by communication mode with multiple charging gun controllers, for example, in Fig. 1 1# rifles charge controller, 2# rifles charge controller, until M# rifle charge controllers.In the present invention, it is preferred to, the money Source dispensing controller is connected by RS485 buses with the multiple charging gun controller.So, the resource allocation controller with Information exchange can be carried out between the multiple charging gun controller.Wherein, interactive information includes charge requirement application, resource Obtain, the information such as resource release.
Each charging gun controller is connected by communication mode with multiple charging modules, such as the 1# in Fig. 1 fills Electric module, 2# charging modules, 3# charging modules, until N# charging modules, wherein M and N can be with identical, can also be different.At this In invention, it is preferable that each charging gun controller is connected by CAN with the multiple charging module.So, just In the charging gun controller control the charging module start whether, so as to control corresponding charging module to pass through the rifle Plug is charged.
Each charging module is connected with power supply grid, in order to provide charging power by power supply grid.And Each charging module passes through the output switching direct-current high-voltage relay in a direct-current high-voltage relay, that is, Fig. 1 Be connected with multiple rifle plugs, such as 1# rifles plug, 2# rifles plug in Fig. 1, until N# rifle plugs.So, the charging module It can be powered to rifle plug, and by robbing plug to charging electric vehicle.
Meanwhile, in the present invention, No. ID, position volume of all charging modules that are stored with the resource allocation manager Number.In addition, No. ID of the charging module that can be charged to each rifle plug that is also stored with the resource allocation manager, Form module information list.So, by the module information list, it has been able to know which charging module can be to which Rifle plug charges.
In addition, the present invention also provides the multiple gun charger charging method that a kind of power output is distributed automatically on demand.Such as Fig. 2 institutes Show, the multiple gun charger charging method that the power output is distributed automatically on demand comprises the following steps:
First, the resource allocation controller is by communication mode, for example, passing through RS485 buses and the multiple charging gun control Device connection processed, in order to information exchange between the two.
Secondly, No. ID of all charging modules, Position Number are entered into the resource allocation controller.So that The resource allocation controller can manage all charging modules.
Again, each rifle plug can be entered into the resource allocation for No. ID of the charging module charged to control In device.So so that the resource allocation controller has been able to know which charging module can give which rifle plug charging.
So, when such as with a certain, rifle plug, when M# rifles plug charges, user is according to vehicle battery charging parameter setting Maximum charging current.
After maximum charging current is set, the maximum that the charging gun controller of the rifle plug will be set according to user Charging current sends charging module demand application to the resource allocation controller.It is, maximum charging current amount is sent To the resource allocation controller, and ask the resource allocation controller distribution charging module.
The resource allocation controller, can be according to the maximum charging current after charging module demand application is received Calculate the charging module quantity for needing to distribute.Calculate need distribute charging module quantity be specially:Need filling for distribution The output current of electric module number=maximum charging current/single charging module.So, the resource allocation controller just can Knowing needs to distribute several charging modules.
After charging module quantity is calculated, the resource allocation controller sends No. ID of idle charging module To the charging gun controller for initiating application, and by these charging modules labeled as by charging gun controller occupancy. Certainly, in this step, the resource allocation controller must be by module information list can give the rifle plug, also It is that M# rifles plug charges and No. ID in idle charging module is sent to the charging gun controller for initiating application.
This transmission process can continue to carry out, until the charging module of charging module quantity >=needs distribution of actually distribution Quantity or remaining idle charging module quantity=0.
Afterwards, No. ID of the charging module that the charging gun controller is just distributed according to the resource allocation controller, control Make corresponding charging module start to be charged, until charging terminates.
In the present invention, making full use of for the ease of charging module resource, after charging terminates, the charging gun controller The resource allocation controller can will be sent back to for the charging module of charging No. ID.Then, the resource allocation control The status modifier of these charging modules is the free time by device.So, when have again it is other charging gun controllers send charging module demand During application, the resource allocation controller can continue to be allocated the charging module.
The multiple gun charger charging method and charger that the power output of the present invention is distributed automatically on demand can be in chargings Control and rifle is charged to which using which charging module, therefore, it is possible to automatically adjust charging according to user's charging needs Power output, and multiple charging guns can share charging module resource, effectively prevent charging resources idle, can make automobile Charged in most fast mode.
The above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not to the present invention Embodiment restriction.For those of ordinary skill in the field, it can also make on the basis of the above description Other various forms of changes or variation.Here all embodiments can not be exhaustive.Every skill for belonging to the present invention Row of the obvious changes or variations that art scheme is extended out still in protection scope of the present invention.
