The beneficial effects of the utility model：
1）A kind of machine rush-harvesting and rush-planting power distribution direct-current charging post system provided by the utility model can give two electricity simultaneously
Dynamic Vehicular charging, power-sharing；On the other hand, when only having charge requirement there are one terminal, if corresponding AC/DC modules group is not
Its demand can be met, another AC/DC module can be switched in, two AC/DC modules are powered simultaneously to a terminal, from
And shorten the charging time.
2）The utility model makes improvement to the power distributing unit of typical machine rush-harvesting and rush-planting power distribution direct-current charging post,
Two contactors have been only used, has reduced cabling, saves space, so as to reduce cost.
Description of the drawings
Fig. 1 is the systematic schematic diagram of the utility model；
Fig. 2 is the systematic schematic diagram of normal power allocation unit in the prior art.
Specific embodiment
As shown in Figure 1, the utility model includes control unit 10, power distributing unit 6, the breaker 1 being sequentially connected in series, defeated
Enter contactor 2, the output terminal of input contactor 2 is serially connected with AC/DC modules group 3, the output terminal difference of AC/DC modules group 3 respectively
Output contactor 4 is serially connected with, the output terminal of output contactor 4 is connected separately with terminal charge interface, input contactor 1, output
The control terminal of contactor 4 is connect respectively with control unit 10.
Power distributing unit 6 includes controller 61 and anode power distribution contactor 62, cathode power distribution contactor 63,
Electronic switch commonly used in the prior art may be used in controller 61, and anode power distribution contactor 62 is connected to two outputs and connects
Between the anode of the input terminal of tentaculum 4, cathode power distribution contactor 63 is connected to the negative of the input terminal of two output contactors
Between pole, anode power distribution contactor 62, cathode power distribution contactor 63 control terminal connect respectively with controller 61, control
Device 61 processed is connect with control unit 10.
The utility model power dividing function control strategy is as follows：
1）If only one terminal charge interface has charge requirement and its corresponding AC/DC modules group power meets BMS（Battery
Management system）Demand, then control unit corresponding output contactor 4 is controlled to be closed, give corresponding terminal electric vehicle power supply.
2）If only one terminal charge interface has charge requirement but its corresponding AC/DC modules group power cannot meet BMS
Demand, then control unit corresponding output contactor is controlled to be closed, another output contactor is controlled to disconnect, while under issue a command to work(
The controller 61 of rate allocation unit 6, control anode power distribution contactor 62, cathode power distribution contactor 63 are closed, two
AC/DC modules group 3 is simultaneously to corresponding terminal electric vehicle power supply.
3）If two terminal charges connect while have charge requirement, control unit controls two output contactors 4 to be closed, together
At present the controller of power distributing unit is issued a command to, allows it that anode power distribution contactor 62, cathode power distribution is controlled to connect
Tentaculum 63 disconnects, and two AC/DC modules groups 3 give corresponding terminal electric vehicle power supply respectively.
