Description

Technical Field

[0001] The present invention relates to the field of charging technology, and in particular to a configuration method, system, device and storage medium for power distribution. Background Art

[0002] With the advancement of charging technology, the current charging station construction plan includes a flexible charging technology that uses a power distribution module. In the basic charging equipment structure, each charging gun is fixedly connected to several power modules through a high-voltage wiring harness. Therefore, if it is a dual-gun 60kW charging pile, a 120kW power module is required. However, in the actual charging process, it is relatively rare for two guns to output 60kW at the same time. In most cases, at least one charging gun does not have the full power output requirement. Therefore, after the 120kW power module is actually equipped, in most cases, some power modules will be idle.

[0003] In charging equipment solutions using a Power Distribution Unit (PDU), the two charging guns have different charging parameters. Therefore, the controller that controls the power module output parameters (voltage / current) needs to independently adjust the voltage / current of each module. However, before controlling this, it must confirm which charging gun the current PDU is assigned to. During wiring installation, it is necessary to manually record or modify the power module number of the PDU input channel. This manual operation increases the operator's skill level and is inevitable for errors. Summary of the Invention

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] See Figure 1, which shows a flow chart of a configuration method for power distribution provided by an embodiment of the present invention. It should be noted that this specification provides method operation steps as described in the embodiment or flow chart, but may include more or fewer operation steps based on conventional or non-creative work. The order of steps listed in the embodiment is only one way of executing the steps among many, and does not represent the only execution order. When the actual system or server product is executed, it can be executed in sequence or in parallel according to the method shown in the embodiment or the accompanying drawings (for example, in a parallel processor or multi-threaded processing environment). Specifically, Figure 1 As shown, the method specifically includes the following steps:

[0045] S101: controlling the closing of a target relay in response to a power distribution request instruction; the closing of the target relay is used to connect a target input channel and a target output channel of the power distribution;

[0046] S102: Traverse the power modules, where there is at least one power module, until a power module corresponding to the target input channel is determined, and perform the following steps during the traversal:

[0047] S103: Control the current output voltage value of the power module;

[0048] S104: collecting the real-time voltage value on the target output channel;

[0049] S105: When the real-time voltage value matches the output voltage value, determining a corresponding relationship between the current power module and the target input channel.

[0050] Furthermore, the relays are distributed in a matrix form with N rows and M columns.

[0051] In the embodiment of the present invention, the relays are distributed in the form of N rows and M columns, in order to fully utilize the power module to provide voltage to the charging device, and also to facilitate monitoring the output voltage to confirm the input channel corresponding to the power module.

[0052] Furthermore, controlling the closing of the target relay in response to the power allocation request instruction further includes: closing a plurality of target relays distributed in the N-row and M-column matrix, wherein the target input channels of the plurality of target relays are all different.

[0053] In an embodiment of the present invention, when determining the correspondence between the power module and the target input channel by closing a relay, one relay may be closed or multiple relays may be closed simultaneously. When multiple relays are closed, it is necessary to ensure that the multiple relays cannot be in the same target input channel at the same time, so as to facilitate determining the correspondence between the power module and the input channel and the output channel, thereby improving work efficiency.

[0054] Furthermore, the relays are distributed in the form of a matrix of N rows and M columns, including: each column of the M columns of relays is located in the same input channel, and the relays located in the same input channel are respectively connected to N preset voltage monitoring devices, and the N preset voltage monitoring devices are used to monitor the real-time voltage value on the output channel.

[0055] In an embodiment of the present invention, a preset voltage monitoring device is installed on the output channel, and the voltage monitoring device is used to monitor the voltage value on the output channel and compare it with the voltage value output by the power module, thereby determining the correspondence between the power module and the input channel and the output channel.

[0056] Furthermore, when controlling the output voltage value of the current power module, the method further includes: controlling the output voltage value of a group of power modules connected in parallel to the power module.

[0057] In an embodiment of the present invention, a plurality of power modules are connected in parallel to achieve the voltage value required by the charging device and to avoid the problem of idle power, so as to provide multiple voltage values ​​for charging devices with different requirements.

[0058] Furthermore, after traversing the power modules, the number of which is at least one, until a power module corresponding to the target input channel is determined, the method further includes:

[0059] Determine whether all power modules are configured with the input channel;

[0060] If so, the configuration process for power allocation ends;

[0061] If not, the next target relay is controlled to close again, and the step of traversing at least one power module is continued until the power module corresponding to the target input channel is determined, until all power modules are configured with the input channel.

[0062] In the embodiment of the present invention, this step is to determine whether all power modules and input channels have been configured.

[0063] Furthermore, if the real-time voltage value does not match the output voltage value, the method further includes:

[0064] Control the output voltage value of the next power module;

[0065] Collecting the real-time voltage value on the target output channel;

[0066] Determining whether the real-time voltage value is equal to the output voltage value of the next power module;

[0067] If yes, determining the correspondence between the next power module and the target input channel;

[0068] If not, continue to control the output voltage value of the power module and collect the real-time voltage value on the target output channel until the real-time voltage value is equal to the output voltage value of the power module.

[0069] In the embodiment of the present invention, when the voltage value monitored by the voltage monitoring device is inconsistent with the voltage value output by the power module, it is necessary to re-control the output voltage value of the next power module, and then collect the voltage value on the output channel until the real-time voltage value is equal to the output voltage value of the power module. This process is a cyclic process. Only when the conditions are met can the correspondence between the power module and the input channel and output channel be completed.

[0070] Here, the power configuration method and the hardware devices used for the configuration are further explained, such as Figure 2 As shown in FIG, a configuration hardware control diagram for power distribution provided by an embodiment of the present invention is provided. The controller (PMU) performs independent voltage / current control and adjustment on each power module according to the power distribution request instruction. Module 1 to x are power modules for outputting parameter voltage / current values; Wire is a connecting line; In i is i input channels; S ij is i*j relays, where the relays are arranged in a matrix to control the connected power distribution channels; Tj is j preset voltage acquisition devices; and Out j is j output channels.

[0071] Specifically, a power distribution unit (PDU) has multiple input channels and output channels, and can map different input channels to different output channels. The working quality of each power module in the input channel is controlled by the controller (PMU). During wiring assembly, different modules can be connected to different input modules of the PDU. The PDU realizes the mapping of the input and output channel relationship, and the PMU needs to control the power modules connected to the input channel according to the output requirements.

[0072] The configuration method corresponding to the hardware control diagram for power distribution is as follows Figure 3 As shown, it is an execution flow chart of a configuration method for power distribution provided by an embodiment of the present invention, the purpose of which is to automatically identify and configure input channels and power modules. Specifically, for example, when all relays in the PDU are in the open state, one of the relays is closed, such as Figure 2In S1-A, the controller (PMU) sequentially controls Modules 1 through Modulex to output a specific voltage value, such as 300V, and performs real-time voltage sampling at outputs TA / TB / … / Tj. If TA samples 300V when Module1 is controlled to output 300V, it can be concluded that the power module corresponding to S1-A is Module1, meaning that the power module configured for PDU input channel In1 is Module1. S1-A is then disconnected, S2-A is closed, and the previously described method is repeated to sequentially control the modules and perform real-time sampling at Tj to determine the power module configured for PDU input channel In 2, Module x. Finally, by sequentially actuating all relays, the power module configured for each PDU input channel can be determined.

[0073] Similarly, by sampling the voltage at sampling point Tj, the charging gun corresponding to each output channel of the PDU can be confirmed.

[0074] It can be seen from the above technical solutions of the embodiment of the present invention that in the embodiment of the present invention, through the power distribution instruction, the controller controls the output voltage value of the power module and the closing of the relay after obtaining the instruction, and uses the preset voltage acquisition device to collect the output voltage value to determine the input channel where the closed relay is located, and then determine the power module configured by the input channel. The above technical solution realizes the automatic identification of the configuration relationship between the input channel and the power module during the charging process of the charging device, so as to reduce the difficulty of on-site wiring installation and prevent hazards caused by human operating errors.

[0087] Power module connection module: used to control the output voltage value of a group of power modules connected in parallel.

[0088] Accordingly, after the traversal module 20, the following steps are included:

[0090] If so, the configuration process for power allocation ends;

[0091] If not, the next target relay is controlled to close again, and the step of traversing at least one power module is continued until the power module corresponding to the target input channel is determined, until all power modules are configured with the input channel.
