The quantity of charging module needed for charging gun successively distributes its required amount of charging module to each charging gun；Alternatively,
At least one charging module first is distributed to each charging gun, if still available free charging module, according still further to described excellent
Sequence in first grade buffer area, and the quantity of the charging module according to needed for each charging gun, successively to each charging gun
Distribute the charging module needed for it；Alternatively,
To each charging gun mean allocation charging module.
Wherein, the quantity of charging module needed for group fills controller and determines each charging gun according to intelligent charge mode.
Mainly include the following types:
(1) it arrives first and first fills, arrives the small charging modes filled afterwards.Confiscating vehicle launch charging instruction, i.e., before start command,
All charging modules are defaulted as idle module in system, and after the starting power-on command of any vehicle, System Priority is provided at least
One 15KW module assignment corresponds to charging gun to it and carries out charging response, preferential full if also available free module in system at this time
Foot first starts the charge requirement of charging vehicle, in the case where meeting first starting charging vehicle demand, if system is also available free
Module then distributes to the vehicle of sub-priority starting charging.During the charging process, preferentially meet vehicle in fast be full of, if BMS
Demand current slowly reduces, then charging module automatically fills extra idle in the case where meeting the charging current of this vehicle
Electric module is given to the use of demand vehicle.
(2) charging modes first filled are arrived first: confiscating vehicle launch charging instruction, i.e., before start command, institute in system
There is charging module to be defaulted as idle module, after receiving vehicle launch order, system does intelligent top grade to vehicle launch instruction and sorts,
It is preferential to meet the charge requirement for first starting charging vehicle, in the case where meeting first starting charging vehicle demand, if system is also
Available free charging module then distributes to the vehicle of sub-priority starting charging, if at this point, system does not have idle module, right
The local monitor display screen display reminding " charging limitation, system are not assigned to idle module " answered, while on the backstage of client
Pass charging limitation or wait state.Preferentially meet vehicle in fast be full of, if charging demand current slowly reduces, charge mould
The charging module of extra free time is given to demand vehicle automatically and used by block in the case where meeting the charging current of this vehicle.
(3) uniform charging mode: confiscating vehicle launch charging instruction, i.e., before start command, all chargings in system
Module is defaulted as idle module, and the quantity N of vehicle launch instruction is received according to system, system power is divided into N equal part, but system
Power should meet be 15KW multiple requirement, if not being able to satisfy power 15KW multiple, by automatic power distribution to preferential starting
Vehicle.By taking 4 rifle of a machine (A, B, C, D) group fills model machine as an example, the distribution condition of each charging gun is as shown in table 1.
| Charging gun rifle number | Start command priority number | Distribution power/KW |
| A | It is inactive | 0 |
| B | 1 | 45 |
| C | 3 | 30 |
| D | 2 | 45 |
Table 1
Further, the group fills after controller is also used to the quantity of the charging module needed for determining a charging gun,
The required amount of charging module being in idle condition is distributed to the charging gun by the state for detecting each charging module, and
The idle group number of the charging module of distribution is changed to the address of charge controller corresponding to the charging gun.
It should be noted that charging module is divided to two kinds of structures by group number and address, wherein group number supports 0-15, address branch
The idle group number held 1-15, and define charging module is 0, and the address of charge controller is 1-12.After distributing charging module,
The group number of the charging module should the address of charge controller corresponding with assigned charging gun it is consistent.
Further, the group fills controller and is also used to the charging module being in idle condition distributing to charging gun
When, first the corresponding group's mold filling block of the charging gun is connected to, then the idle group number of the charging module is changed to described
The address of charge controller corresponding to charging gun；
When the charging module that will distribute to charging gun releases, the charging module is first set to shut down, then control the charging
The connection of the corresponding group's mold filling block of rifle disconnects, and then the group number of the charging module is changed to idle group number.
Wherein, when charging module is from idle state to when needing to be assigned occupancy, it is necessary to which first control group fills module hardware and cuts
Corresponding charging gun channel is changed to, then corresponding charge controller address is changed to charging module group number.When charging module is from being divided
When with occupied state to idle state, it is necessary to first shut down to the charging module, then control group and fill module hardware disconnection and filled with corresponding
Electric rifle channel connection, could be changed to idle group number for the group number of charging module.Charging module cannot be occupied from current charging gun
It is assigned directly to other charging gun channels, it is necessary to first switch to idle state, be redistributed to next charging gun for needing to occupy.
Charging system for electric automobile provided in an embodiment of the present invention can connect by the way that group's mold filling block is corresponding with charging gun
It connects, the charging current of N number of charging module is made arbitrarily to be output to any charging gun, and by software algorithm, intelligence is electric car
