Compared with existing charging method, multiple gun charger charging method that output power of the invention distributes 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 Therefore charging can charge according to user and need to automatically adjust charging output power, and multiple charging guns can share charging Module resource is effectively prevented charging resources idle, automobile can be made to be charged in most fast mode.
Detailed description of the invention
Fig. 1 is the composition schematic diagram of charger of the invention.
Fig. 2 is the flow chart for the multiple gun charger charging method that output power of the invention distributes automatically on demand.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, and the content of embodiment is not as to guarantor of the invention Protect the limitation of range.
Fig. 1 shows the composition schematic diagram of charger of the invention.As shown in Figure 1, charger of the invention includes resource Dispensing controller.The resource allocation controller for realizing charging resource management.
Wherein, the resource allocation controller is connected by communication mode with multiple charging gun controllers, for example, in Fig. 1 1# rifle charge controller, 2# rifle charge controller, until M# rifle charge controller.In the present invention, it is preferred to the money Source dispensing controller is connect by RS485 bus with the multiple charging gun controller.In this way, 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 It obtains, the information such as resource release.
Each charging gun controller passes through communication mode and is connected with multiple charging modules, and the 1# of example as shown in figure 1 fills Electric module, 2# charging module, 3# charging module, until N# charging module, wherein M and N may be the same or different.At this In invention, it is preferable that each charging gun controller passes through CAN bus and is connected with the multiple charging module.In this way, just Whether the charging gun controller controls the booting of the charging module, so that controlling corresponding charging module passes through the rifle Plug charges.
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 switching direct-current high-voltage relay of the output in a direct-current high-voltage relay, that is, Fig. 1 It is connected with multiple rifle plugs, example 1# rifle plug as shown in figure 1,2# rifle plug, until N# rifle plug.In this way, the charging module It can power to rifle plug, and be charged by robbing plug to electric car.
Meanwhile in the present invention, the ID number of all charging modules is stored in the resource allocation manager, position is compiled Number.In addition, the ID number for the charging module that can be charged to each rifle plug is also stored in the resource allocation manager, Form module information list.In this way, being able to know which charging module can be to which by the module information list The charging of rifle plug.
In addition, the present invention also provides a kind of multiple gun charger charging methods that output power distributes automatically on demand.Such as Fig. 2 institute Show, the multiple gun charger charging method that the output power distributes automatically on demand the following steps are included:
First, the resource allocation controller is by communication mode, for example, passing through RS485 bus and the multiple charging Gun controller connection, in order to information exchange between the two.
Secondly, the ID number 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, the ID number for the charging module that each rifle plug can be used to charge the resource allocation is entered into control In device.In this way, the resource allocation controller is enabled to be able to know which charging module gives which rifle plug charging.
In this way, working as with a certain rifle plug, such as when the charging of M# rifle plug, user is according to vehicle battery charging parameter setting Maximum charging current.
After setting maximum charging current, the charging gun controller of the rifle plug will be according to maximum set by user Charging current sends the application of charging module demand to the resource allocation controller.It is, maximum charging current amount is sent To the resource allocation controller, and request the resource allocation controller distribution charging module.
The resource allocation controller, can be according to the maximum charging current after receiving charging module demand application Calculate the charging module quantity for needing to distribute.Calculate the charging module quantity for needing to distribute specifically: need to distribute fills Electric module number=maximum charging current/single charging module output electric current.In this way, the resource allocation controller can Know and needs to distribute several charging modules.
After calculating charging module quantity, the resource allocation controller sends the ID number 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 be to the rifle plug, also It is that M# rifle plug charges and the ID number 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 quantity >=needs distribution charging module actually distributed Quantity or remaining idle charging module quantity=0.
Later, the charging gun controller is just according to the ID number of the charging module of resource allocation controller distribution, control It makes corresponding charging module booting to charge, until charging terminates.
In the present invention, making full use of for the ease of charging module resource, after charging, the charging gun controller The ID number for the charging module for being used to charge can be sent back to the resource allocation controller.Then, the resource allocation control The status modifier of these charging modules is the free time by device.In this way, ought there are other charging gun controllers to issue charging module demand again When application, the resource allocation controller can continue to be allocated the charging module.
The multiple gun charger charging method and charger that output power of the invention distributes automatically on demand can be in chargings It controls and rifle is charged to which using which charging module, therefore, can be charged according to user and need to automatically adjust charging Output power, and multiple charging guns can share charging module resource, effectively prevent charging resources idle, can make automobile It is charged in most fast mode.
The above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be to the present invention Embodiment restriction.For those of ordinary skill in the art, it can also make on the basis of the above description Other various forms of variations or variation.Here all embodiments can not be exhaustive.It is all to belong to skill of the invention The obvious changes or variations that art scheme is extended out are still in the scope of protection of the present invention.
