Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
It should be noted that, the user information (including but not limited to user equipment information, user personal information, etc.) and the data (including but not limited to data for presentation, analyzed data, etc.) related in the present application are both information and data authorized by the user or sufficiently authorized by each party; correspondingly, the application also provides a corresponding user authorization entry for the user to select authorization or select rejection.
In the conventional method, the split charger has a topology structure of one power control module to a plurality of charging main control modules, as shown in fig. 1, and under this architecture, the number of charging main control modules and rectifying modules carried by the power control modules is limited. In order to realize power expansion, more rectification modules are required to be additionally added, and meanwhile, the CAN communication wires of the newly added rectification modules are combined into the original CAN bus, so that the utilization rate of the CAN bus is increased, and when the utilization rate exceeds 70%, bus blockage CAN be caused, and abnormal communication occurs.
For example, the split type charger in the charging station uses one power control module to complete the power distribution of all charging guns in the charger, and additional independent chargers need to be added for the situation that the charging station enlarges the total charging power, as shown in fig. 2, the charging modules in different independent systems cannot be mutually called (for example, the independent systems n of the independent systems 1 and … cannot be mutually called), and when the power control module in a certain system or a rectifying circuit corresponding to the power control module fails, all charging guns on the charger corresponding to the system cannot be used.
For example, when the architecture is adopted for setting, power expansion is required to be realized through an additional newly-added rectifying module, the CAN bus utilization rate is too high, communication between the power control module and the charging main control module is also affected identically, and when more charging interfaces are required to be additionally arranged, such as a newly-added charging gun, the CAN bus utilization rate is increased, and bus blockage is easily caused when the CAN bus utilization rate is too high, so that the quantity of the carried rectifying modules and the charging main control modules is affected.
In one embodiment, as shown in fig. 3, a method for allocating a charging power expansion capacity is provided, and this embodiment is exemplified by the method being applied to a power expansion capacity allocation system corresponding to a charging station, where the power expansion capacity allocation system may include a plurality of power control components, and a plurality of charging master components connected to the plurality of power control components, where each charging master component may be connected to the same number of charging guns, and different power control components are communicatively connected to different charging guns corresponding to each charging master component. In this embodiment, the method includes the steps of:
the charging request power may be a request power of a charging object connected to any charging gun; the charging output power may be the output power of a power control component communicatively coupled to any of the charging guns; the charge allocated power may be allocated based on a power control component other than the power control component communicatively coupled to any of the charging guns.
As an example, as shown in fig. 4, the architecture diagram of the power expansion allocation system may include m rectifying modules (i.e. rectifying components), n power control modules (i.e. power control components), and p charging main control modules (i.e. charging main control components), where n is greater than or equal to 2 p and greater than or equal to n, each power control module may be respectively and correspondingly connected with m rectifying modules, each charging main control module may be connected with n charging guns, and the 1 st, n+1th, … …, and (p-1) n+1st charging guns are in communication connection with the 1 st power control module (e.g. based on CAN1 network connection) through the respective corresponding charging main control modules, i.e. different power control components may be in communication connection with different charging guns corresponding to each charging main control component based on different CAN networks.
In practical application, based on the power expansion topological structure of the power expansion allocation system, a plurality of charging guns connected with the charging main control assembly are arranged, a plurality of charging guns connected with other charging main control assemblies are in one-to-one correspondence, and the charging guns in one-to-one correspondence are connected with the same power control assembly through the charging main control assemblies corresponding to the charging guns, so that when one of the power control assemblies cannot output power to cause that the corresponding charging gun cannot be used, other charging gun corresponding to the same charging main control assembly can normally send power requests to other power control assemblies through the corresponding communication buses, and normal use of the charging gun can be restored.
In an example, the number p of charging master components may be greater than the number n of power control components, or may be equal to n. When p=n, namely the number of the power control components and the number of the charging main control components, the number of the charging guns connected with each charging main control component is the same, and the corresponding framework diagram is shown in fig. 5; when p > n, the corresponding framework diagram is shown in fig. 6, so that the charging power of other charging modules CAN be regulated and the CAN bus utilization rate is reasonably arranged based on the power expansion topological structure of the power expansion regulating system, and the problems that the expansion is limited and all charging guns cannot be used when the charging modules of the charger fail are solved.
In a specific implementation, two adjacent charging guns in n charging guns connected with the charging main control assembly can be connected through the switch control assembly, when the voltage of the voltage input end of the allocated charging gun is detected to exceed a threshold value, the switch control assembly connected between any charging gun and the allocated charging gun is controlled to be switched into a communication state from a disconnection state, and then the output voltage of the rectifying assembly corresponding to the allocated charging gun can be output to any charging gun so as to charge a charging object.
In an example, aiming at the situation that any power control component cannot output power and a corresponding charging gun cannot be used, by requesting power allocation and setting a switch control component between charging guns connected with the same charging main control component, a communication control relation exists among all charging guns corresponding to the same charging main control component, so that idle charging power of any power control component can be allocated, and free allocation of power expansion and power of a rectifying component aiming at the currently used charging gun can be effectively realized.
Compared with the traditional method, in the technical scheme of the embodiment, when the charging request power required by the charging vehicle end is larger than the charging output power corresponding to the charging gun for starting charging, the address of other charging guns with a conduction control relationship is allocated through the corresponding charging main control component, the power allocation request is sent to the power control component corresponding to the allocated charging gun to acquire the output voltage, and the voltage input ends between the other charging guns and the charging gun for starting charging are controlled to be conducted through the corresponding switch control component, so that the charging power allocated from the other rectifying components is provided to the charging gun for starting charging, the free allocation of the power capacity of the charger and the charging total power of the charging station is realized, and the utilization rate of the charging module is effectively improved.
In the charging power expansion allocation method, a power expansion allocation system corresponding to a charging station is built based on at least two split chargers, then under the condition that charging request power corresponding to any charging gun in the charging station is detected to be larger than charging output power, power allocation is requested through a charging main control component corresponding to any charging gun, charging allocation power is obtained, allocation voltage corresponding to the charging allocation power is further output to any charging gun, charging operation is carried out on a charging object through any charging gun, the charging main control component can allocate idle charging power of any power control component through the requested allocation power, power expansion and free power allocation can be effectively achieved, and the utilization rate of a charging module is improved.
In an embodiment, when it is detected that the charging request power corresponding to any charging gun in the charging station is greater than the charging output power, the charging main control component corresponding to any charging gun requests power allocation, so as to obtain the charging allocation power, which may include the following steps:
when any charging gun in the charging station is started to charge, acquiring the charging request power according to a charging object connected with any charging gun, and acquiring the charging output power according to the power control component in communication connection with any charging gun; and if the charging request power is larger than the charging output power, requesting power allocation through a charging main control component corresponding to any charging gun to obtain the charging allocation power.
In practical application, taking electric automobile charging as an example, for a certain charging main control component, when a charging gun (i.e. any charging gun) connected with the charging main control component starts charging, and the charging power (i.e. charging request power) of a vehicle to be charged (i.e. a charging object) is larger than the current available power (i.e. charging output power) of a power control component corresponding to the charging gun, the charging main control component corresponding to the charging gun can be selected as a charging gun for allocation, and the address of the charging gun for allocation is obtained to send a power allocation request to a power control component corresponding to the charging gun for allocation, so as to request power allocation, and obtain charging allocation power.
In an alternative embodiment, the current available power of the power control component may be the outputtable power of all of the rectifying components to which the power control component is connected, except for the rectifying components currently occupied by other charging guns, and the rectifying components that are inoperable due to their own faults.
In this embodiment, when any charging gun in the charging station starts charging, charging request power is obtained according to a charging object connected with any charging gun, and charging output power is obtained according to a power control component in communication connection with any charging gun, if the charging request power is greater than the charging output power, power allocation is requested through a charging main control component corresponding to any charging gun, so as to obtain charging allocation power, and free allocation of power expansion and charging total power of the charging station can be realized.
In an embodiment, the step of requesting power allocation by the charging master control component corresponding to the any charging gun to obtain the charging allocation power may include the following steps:
determining to allocate the charging gun from the charging guns except any charging gun connected with the charging main control assembly corresponding to any charging gun; the charging main control assembly is connected with at least two charging guns; and requesting power allocation to the power control component in communication connection with the allocation charging gun through the charging main control component corresponding to any charging gun to obtain the charging allocation power.
In an example, as shown in fig. 5, the corresponding address identifiers may be sequentially arranged and set according to the connection sequence of the charging gun and the corresponding charging master control assembly, when power is allocated to any charging gun (such as charging gun 1 in fig. 5), the state of the charging gun (such as charging gun 2 in fig. 5) corresponding to the next address identifier connected to the corresponding charging master control assembly (such as charging master control assembly 1 in fig. 5) may be determined, and if the charging gun is in an idle state, the charging gun may be selected as the allocated charging gun.
For example, by acquiring the address identifier (i.e., address information, for example addr=0 in fig. 5) of the charging gun 1 in fig. 5, the sequential determination may be performed based on the arrangement order of the address identifiers, if the charging gun of the next address identifier is currently charging, the determination may be skipped, and the determination of the state of the charging gun of the next address identifier may be continued until the charging gun in the idle state is found as the deployment charging gun.
In an alternative embodiment, the current available power of the power control component corresponding to the charging gun can be obtained, the sum of the current available power and the current available power of the power control component corresponding to any charging gun is used as new available power, then when the charging power of the vehicle to be charged is smaller than or equal to the new available power, power allocation of the rectifying component corresponding to the charging gun can be executed, if the charging power is larger than the new available power, other charging guns which are connected with the charging main control component corresponding to any charging gun and are in an idle state can be selected continuously to be complementary charging guns based on the address sequence, and further different complementary charging guns can be selected circularly until the charging power of the vehicle to be charged is smaller than or equal to the sum of the current available power corresponding to any charging gun and the current available power corresponding to all the charging guns.
In this embodiment, the charging gun is determined to be allocated by the charging gun except any charging gun connected to the charging main control component corresponding to any charging gun, and then the power allocation is requested to the power control component in communication connection with the allocated charging gun by the charging main control component corresponding to any charging gun, so as to obtain the charging allocation power, and the problem that all charging guns cannot be used when the charging module of the charger fails can be solved.
In one embodiment, the step of requesting power allocation from the power control component in communication connection with the allocating charging gun by the charging master control component corresponding to any charging gun to obtain the charging allocation power may include the following steps:
generating a power request message through a charging main control component corresponding to any charging gun according to the address information corresponding to the allocation charging gun; and sending the power request message to the power control component in communication connection with the dispatching charging gun to obtain the charging dispatching power aiming at the power request message.
In practical application, each power control component may be provided with a unique address identifier, for example, the address ranges from 0 to n-1, each power control component may manage m rectifying components, each rectifying component may also have a unique address identifier, and the charging main control component may be configured with multiple guns, that is, the number of charging terminals may be two or more. Each charging main control assembly can be provided with n charging guns, each charging gun can be provided with a unique address identifier, namely, the number of charging guns configured by each charging main control assembly is consistent with the number of used power control assemblies, and the address identifier starts from 0.
In the communication mode, the address identifier of any power control component is set as X, the address identifier of any charging gun is set as Y, and the communication between the charging gun and the power control component meets the following corresponding relation:
X=Y mod n
wherein X is the remainder of Y divided by n.
Specifically, under the condition of the power expansion topological structure shown in fig. 4, the newly-added power control component CAN be used for communicating with the newly-added rectifying component, and the communication line of the newly-added rectifying component does not need to be connected to the original CAN bus, so that the power expansion CAN be realized under the condition that the communication of the original rectifying component is not affected; similarly, the addition of the charging gun and the communication mode between the charging gun and the power control component can be realized based on the topological structure of fig. 4, and the address identifier of the charging gun meets the above conditions. The different power control components have corresponding relations with the corresponding different charging guns through the charging main control component, and based on the connection mode, messages of all the charging guns CAN be prevented from being concentrated on the same CAN bus.
In an example, as shown in fig. 6, the communication between the charging gun 1 and the power control component 1 satisfies the condition of x=y mod N, so that when the charging demand power of the vehicle end is greater than the output capability of the power control component corresponding to the charging gun connected to the vehicle end, the charging master control component 1 corresponding to the charging gun 1 CAN send a camouflage message (i.e. a power request message) to the charging gun corresponding to the charging gun 2 through the CAN bus, so that the power of the power control component 2 is distributed, and the corresponding relay K1 CAN be closed, thereby achieving the effect of allocating the power as required.
In this embodiment, according to the address information corresponding to the charging gun, the charging master control component corresponding to any charging gun generates the power request message, and then sends the power request message to the power control component in communication connection with the charging gun, so as to obtain the charging allocation power for the power request message, thereby effectively realizing power expansion and free power allocation and improving the utilization rate of the charging module.
In one embodiment, each charging master control assembly is connected with a plurality of rectifying assemblies, the voltage for outputting the charging power to any charging gun, and the charging operation is performed on the charging object by any charging gun, which may include the following steps:
determining a rectifying component in an idle state corresponding to the power control component in communication connection with the deployment charging gun; and outputting the allocated voltage corresponding to the charging allocation power to any charging gun based on the voltage output to the allocated charging gun by the rectifier assembly in the idle state, and carrying out charging operation on the charging object by any charging gun.
In one embodiment, each charging gun corresponding to each charging master control component is connected through a switch control component, and the method for outputting the blended voltage corresponding to the charging blended power to any charging gun based on the voltage output to the blended charging gun by the rectifying component in the idle state may include the following steps:
When the voltage of the input end corresponding to the allocation charging gun exceeds a preset threshold, controlling the switch control assembly between the allocation charging gun and any charging gun to be communicated, and outputting the allocation voltage corresponding to the charging allocation power to any charging gun.
In practical application, the switch control component can be a relay, and in the aspect of power distribution, adjacent charging guns corresponding to the same charging main control component can be connected through the relay, so that any charging gun can use rectifying components managed by different power control components.
In one embodiment, the method may further comprise the steps of:
when the allocation charging gun is detected to be in a starting charging state, the switch control assembly between the allocation charging gun and any charging gun is controlled to be switched from a communicating state to a disconnecting state, so that the allocation charging gun executes the current charging operation.
In an example, when the charging gun is detected to start charging, the switch control component connected between any charging gun and the charging gun is controlled to switch from the on state to the off state, so that the rectifying component corresponding to the charging gun can normally output voltage to the charging gun, and the corresponding charging process is performed. Therefore, the split charger is modularized, a plurality of traditional independent systems CAN be combined into a whole system, the utilization rate of a CAN bus CAN be reasonably arranged, the total charging power CAN be increased, the power of the rectifier assemblies in the idle state corresponding to other charging guns CAN be allocated as required in the charging process, the utilization rate of the rectifier assemblies is improved, and the power of the whole system after capacity expansion CAN be switched along with the change of the demand through coupling power distribution aiming at the whole system after capacity expansion, so that the free power distribution of the whole system is realized.
In order to enable those skilled in the art to better understand the above steps, the embodiments of the present application will be exemplarily described below by way of example with reference to fig. 5 and 6, but it should be understood that the embodiments of the present application are not limited thereto.
As shown in fig. 5, a p=n architecture diagram is provided with 3 power control components and 3 charging main control components, each charging main control component is equipped with 3 charging guns, and 9 charging guns are provided, wherein the addresses of the power control components are identified as 0 to 2, the addresses of the charging main control components are identified as 0 to 2, the addresses of the charging guns are identified as 0 to 8, and the corresponding connection relationship between the charging guns and the charging main control components is shown in fig. 5. The power control component with address identification 0 can communicate with the charging guns with address identification 0, 3 and 6, the power control component with address identification 1 can communicate with the charging guns with address identification 1, 4 and 7, and the power control component with address identification 2 can communicate with the charging guns with address identification 2, 5 and 8. The charging gun 1 and the charging gun 2 are provided with a relay K1, the charging gun 2 and the charging gun 3 are provided with a relay K2, the charging gun 4 and the charging gun 5 are provided with a relay K3, the charging gun 5 and the charging gun 6 are provided with a relay K4, the charging gun 7 and the charging gun 8 are provided with a relay K5, and the charging gun 8 and the charging gun 9 are provided with a relay K6.
When the charging requirement of the charging gun 1 with the address mark of 0 is greater than the available output power of the power control component with the address mark of 0, the charging main control component 1 can send a disguised message to the power control component with the address mark of 1 so as to request power allocation. It should be noted that, the precondition for sending the masquerade message to request power allocation is that the charging gun 2 with address identifier 1 is in an idle state, i.e. not in a charging start state.
Fig. 6 shows an architecture diagram of p > n, which is provided with 2 power control components and 4 charging master components, each charging master component is equipped with 2 charging guns, and total 8 charging guns. Wherein, the PCM address of the power control component is 0 and 1 respectively; the CCM addresses of the charging main control component are respectively 0, 1, 2 and 3; the addresses of the charging guns are 0, 1 to 7. The charging guns 1, 3, 5, 7 CAN communicate with the PCM1 (i.e., the power control assembly 1) through CCM-CAN1, and the charging guns 2, 4, 6, 8 CAN communicate with the PCM2 (i.e., the power control assembly 2) through CCM-CAN 2. The rectifying module 1 … n corresponding to the power control module 1 CAN be communicated with the power control module 1 through the PCM-CAN1, and the rectifying module 1 … n corresponding to the power control module 2 CAN be communicated with the power control module 2 through the PCM-CAN 2.
If the charging gun 1 starts charging, the charging gun 1 may send a power request instruction to the power control component 1, and when the charging gun 1 starts charging and the power control component 1 receives that the power requirement of the vehicle end is greater than the current available power, the power control component 1 may send a requirement message through the CCM-CAN2 bus by using the frame ID (e.g. address identifier) of the charging gun 2, so as to request the power distribution of the power control component 2, so that the rectifying component controlled by the power control component 2 outputs power to the charging gun 2; the relay K1 may be controlled to be closed after detecting that the input terminal voltage of the charging gun 2 is up, so that the voltage to be input to the charging gun 2 is output to the charging gun 1. If the charging gun 2 starts charging at this time, the relay K1 may be turned off.
When the charging gun 1 starts charging, the current available power of the power control component 1 may be the total power subtracted from the charging power occupied by the charging gun being charged in the charging guns 3, 5, 7, and if the charging gun 3, 5, 7 is not started charging at this time, the current available power of the power control component 1 is the total power.
