Fig. 4 shows a charging system with two charging guns, and fig. 2 shows a schematic diagram of a power distribution controller. The charging power distributor comprises a normally open contact switch 1-1K1, a normally closed contact switch 1-1K1, a normally open contact switch 1-1K2 and a normally closed contact switch 1-1K2, wherein the normally open contact switch 1-1K2 and the normally closed contact switch 1-1K2 are auxiliary normally open contact switches and auxiliary normally closed contact switches of control switches 1K1 and 1K2 in the charging power distributor A, and control coils 1-K1M and 1-K2M are matched with the control switches 1K1 and 1K2 of the charging power distributor A; the normally open contact switch 2-1K1, the normally closed contact switch 2-1K1, the normally open contact switch 2-1K2 and the normally closed contact switch 2-1K2 are auxiliary normally open contact switches and auxiliary normally closed contact switches of control switches 1K1 and 1K2 in the B charging power distributor, and the control coils 2-K1M and 2-K2M are matched with the control switches 1K1 and 1K2 of the B charging power distributor.
Taking charging of an electric vehicle as an example, when a charging gun 1 has a charging demand, a charging pile controller issues a command, assuming that a charging module is needed at this time, a port 1 and a port 2 of a charging power distributor A respectively pass through a normally closed contact switch 2-1K1 and a normally closed contact switch 2-1K2 of a control switch 1K1 and a control switch 1K2 in a charging power distributor B, then control coils 1-K1M and 1-K2M matched with the control switches 1K1 and 1K2 of the charging power distributor A, and after the control coils 1-K1M and 1-K2M are powered on, the control switches 1K1 and 1K2 of the charging power distributor A are closed, the normally open contact switches 1-1K1 and 1-1K2 are also closed, the charging gun 1 charges the equipment to be charged, and meanwhile, the information that the control switches 1K1 and 1K2 of the charging power distributor A are closed is sent to the charging pile controller.
If when rifle 1 charges for electric motor car 1 at charging, rifle 2 also has the demand of charging, under the condition of the information that electric pile controller received A charging power distributor's control switch 1K1, 1K2 has been closed under normal conditions, no longer let B charging power distributor's control switch 1K1, 1K2 closed, can cause the group battery of two electric motor cars to connect in parallel like this, the group battery of high voltage takes place the heavy current with the group battery of low voltage in the twinkling of an eye and charges, cause the potential safety hazard. And the charging pile controller issues an error instruction to close control switches 1K1 and 1K2 of the charging power distributor B, and at the moment, because a port 1 and a port 2 of the charging power distributor B pass through normally closed contact switches 1-1K1 and 1-1K2 of control switches 1K1 and 1K2 in the charging power distributor A respectively, control coils 2-K1M and 2-K2M of 1K1 and 1K2 are controlled. The 1K1 and 1K2 coils 1-K1M and 1-K2M of the charging power divider A are already electrified and closed, and the normally closed contact switches 1-1K1 and 1-1K2 of the charging power divider A are opened, so that the control switches 1K1 and 1K2 coils 2-K1M and 2-K2M of the charging power divider B are not electrified and closed, and the problem of parallel connection of the battery packs of two electric vehicles is effectively solved.
When the charging gun 2 is charged firstly, the port 1 and the port 2 of the charging power distributor B pass through the normally closed contact switches 1-1K1 and 1-1K2 of the control switches 1K1 and 1K2 in the charging power distributor A respectively, then control coils 2-K1M and 2-K2M of the control switches 1K1 and 1K2 are controlled, after the coils are electrified, the control switches 1K1 and 1K2 are closed, the auxiliary normally open contact switches 1-1K1 and 1-1K2 are also closed, the charging gun 2 charges the electric vehicle, and information that the 1K1 and the 1K2 are closed is sent to the charging pile controller.
If charging gun 1 wants to charge when charging gun 2 charges, port 1 and port 2 of the charging power distributor a pass through normally closed contact switches 2-1K1 and 2-1K2 of control switches 1K1 and 1K2 in the charging power distributor B respectively, and then control coils 1-K1M and 1-K2M matched with control switches 1K1 and 1K2 of the charging power distributor a, control coils 2-K1M and 2-K2M matched with control switches 1K1 and 1K2 of the charging power distributor B are already powered on and closed, and normally closed contact switches 2-1K1 and 2-1K2 of the charging power distributor B are off, so that control coils 1-K1 58M 9 and 1-K2 of control switches 1K1 and 1K2 of the charging power distributor a cannot be powered on and cannot be powered on.
Similarly, when the loops of the control switches 1K1 and 1K2 in the charging power distributor A cannot be disconnected (i.e. adhesion occurs) due to fault closure, the normally closed auxiliary contact switches 1-1K1 and 1-1K2 of the charging power distributor A are normally open, and the control coils 2-K1M and 2-K2M of the charging power distributor B, which are matched with the control switches 1K1 and 1K2, cannot be electrically closed.
Optionally, when the system includes three charging guns, the working principle is the same as that described above (as shown in fig. 3), in practical application, a plurality of charging guns can be set by the method described above, so as to avoid the problem of parallel connection of battery packs in the morning due to control error or control switch adhesion in a multi-charging gun mode, and solve the potential safety hazard caused by parallel connection of battery packs.
The charging unit at least comprises two charging units, and optionally, the connection mode of the two charging units can be as follows: one output interface in two adjacent charging units is connected with the input interface electric connection of another charging unit, and the output interface of another charging unit is connected with the rifle that charges, fills electric pile controller and each charging unit's the module electric connection that charges, fills electric pile controller and each charging unit's communication mouth electric connection and communicate.
As shown in fig. 7, the number of the charging units is two, and the charging units include two parts, I and II, I's output interface and II's input interface electric connection, II's output interface and charging gun 1 are connected, charging pile controller and I and II's charging module electric connection, charging pile controller and a charging power distributor and B charging power distributor's communication port electric connection, charging gun 1 is connected with the electric vehicle. Specifically, the components of section I are shown in fig. 8, and the components of section II are shown in fig. 9. This arrangement may increase the power of the charging system to accommodate greater charging power requirements.
Taking the charging system comprising the two charging units as an example, the electric vehicle 1 communicates with the charging pile controller to inform the electric vehicle 1 of the required voltage and current, the charging pile controller receives the information, the information is processed and communicated with the charging module to control the output voltage and the output current of the charging module to be the required voltage and current, the communication ports of the charging power distributor A and the charging power distributor B are communicated with the charging power distributor A and the charging power distributor B, and the control switch corresponding to the required charging module is controlled to be closed to finish the charging of the electric vehicle.
In practical application, the number of the charging units can be reasonably set and connected according to the power required by the equipment to be charged.
Optionally, when the charging system includes at least two charging units, the connection manner between the two charging units may also be the method shown in fig. 4: the charging unit A comprises two charging units A and B, a communication port of a charging module in the charging unit A is connected with a charging pile controller, a communication port of a charging power distributor A is connected with a communication port of a charging power distributor B and then is connected with the charging pile controller, a 1M1-5M1 interface of the charging unit A is respectively connected with an output of the charging module 1-5M 3538, and a 1M2-5M2 interface of the charging unit A is respectively connected with a 1M2-5M2 of the charging unit B. The output interface of the charging unit A is connected with the charging gun 1 and then connected with the equipment to be charged 1, and the output interface of the charging unit B is connected with the charging gun 2 and then connected with the equipment to be charged 2. The setting can realize the dilatation to the rifle that charges like this for when treating the battery charging outfit increase, charging system can charge for treating the battery charging outfit simultaneously, avoids the condition that the rifle number of charging is not enough.
Specifically, the charging system adopting the above connection mode can be used for charging two electric vehicles:
when only the electric vehicle 1 is charged, the electric vehicle 1 communicates with a charging pile controller to inform the electric vehicle of the voltage and the current required by the electric vehicle 1, the charging pile controller receives information, the charging pile controller communicates with a charging module through information processing to control the output voltage and the output current of the charging module to be the required voltage and current, the charging pile controller communicates with a power distribution controller through a communication port of an A charging power distributor, and a control switch corresponding to the charging module for controlling the required power is closed to finish charging of the electric vehicle 1.
When only the electric vehicle 2 is charged, the electric vehicle 2 communicates with the charging pile controller to inform the electric vehicle of the voltage and the current required by the electric vehicle 2, the charging pile controller receives information, the information processing and the charging module communication control device controls the output voltage and the output current of the charging module to be required voltage and current, the communication port of the charging power distributor B is communicated with the power distribution controller, and the control switch corresponding to the charging module controlling the required power is closed to complete the charging of the electric vehicle 2.
When the electric vehicle 1 and the electric vehicle 2 need to be charged simultaneously, the electric vehicle 1 and the electric vehicle 2 communicate with the charging pile controller to inform the electric vehicle 1 and the electric vehicle 2 of the required voltage and current, the charging pile controller receives information, for example, the electric vehicle needs the power of 2 charging modules, the electric vehicle 2 needs the power of 3 charging modules, after information processing, the charging pile controller communicates with the charging modules to control the output voltage and the output current of the charging modules, the charging pile controller communicates with the power distribution controller of the charging power distributor A through the communication port of the charging power distributor A, the control switches 1K1, 1K2, 2K1 and 2K2 corresponding to the charging modules controlling the required power are closed to complete the charging of the electric vehicle 1, and meanwhile, the charging pile controller communicates with the power distribution controller of the charging power distributor B through the communication port of the charging power distributor B, and the control switches 3K1, 3K2, 4K1, 4K2, 5K1 and 5K2 corresponding to the charging module for controlling the required power are closed, so that the electric vehicle 2 is charged.
