Description

Technical Field

[0001] The present application relates to the field of charging technologies, and in particular, to a control method for a charging and battery swapping station, a charging and battery swapping station, a control device, and a control apparatus. Background Art

[0002] To solve the problem of the endurance of new energy vehicles and meet the vehicle energy replenishment requirements, a new energy replenishment method, i.e., battery swapping service, is provided while being compatible with off-station charging piles. Specifically, when the number of available battery packs in the charging and battery swapping station is large, the corresponding charging modules are in an idle state. To improve resource utilization, the charging modules in the station are connected to off-station charging piles to provide energy replenishment services for more vehicle models that cannot swap batteries.

[0003] How to make greater use of the charging resources in the station and improve the energy replenishment capacity of the charging and battery swapping station is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] In view of this, the present application provides a control method for a charging and battery swapping station, a charging and battery swapping station, a control device, and a control apparatus to improve the energy replenishment capacity of the charging and battery swapping station.

[0005] To solve the above problems, the technical solutions provided by the present application are as follows:

[0006] In the first aspect of the present application, a control method for a charging and battery swapping station is provided. The charging and battery swapping station includes a charging module, an off-station charging pile, and an in-station battery storage. The charging module is configured to output electric energy to the off-station charging pile and / or the in-station battery storage. The method includes:

[0007] Obtaining the in-station charging demand of the in-station battery storage and the off-station charging demand of the off-station charging pile;

[0008] Determining a control strategy according to the in-station charging demand and the off-station charging demand, and allocating the charging module by using the control strategy. The control strategy is used to allocate the maximum number of idle charging modules to the off-station charging pile while satisfying the in-station charging demand.

[0009] In a possible implementation manner, the determining a control strategy according to the in-station charging demand and the off-station charging demand includes:

The control strategy is used to ensure that at least one charging module is allocated to the off-station charging pile with the off-station charging demand while satisfying the in-station charging demand.

[0011] If there is the in-station charging demand and the in-station charging demand includes a high-power charging demand and a low-power charging demand, a control strategy is determined according to the principle that the priority of the high-power charging demand is higher than that of the low-power charging demand. The control strategy is used to allocate a first number of the charging modules to the in-station battery compartments with the high-power charging demand, and the first number of the charging modules can meet the high-power charging demand of the in-station battery compartments;

[0012] If the in-station battery compartments include a first battery compartment and a second battery compartment and both the first battery compartment and the second battery compartment have high-power charging demands, a control strategy is determined according to the SOC of the batteries in the first battery compartment and the SOC of the batteries in the second battery compartment. The control strategy is used to allocate a second number of the charging modules to the batteries with high SOC, and the second number of the charging modules can meet the high-power charging demand of the batteries with high SOC.

[0013] In a possible implementation manner, if there are both the out-station charging demand and the in-station charging demand at the same time, the control strategy is used to allocate the charging modules, including:

[0014] If the occurrence time of the out-station charging demand is earlier than that of the in-station charging demand and the remaining charging modules cannot meet the in-station charging demand, control the out-station charging pile to release the charging modules, and use the released charging modules for in-station charging;

[0015] If the occurrence time of the in-station charging demand is earlier than that of the out-station charging demand and there are no remaining charging modules for out-station charging, control the first target battery compartment to release one charging module, and use the released charging module for out-station charging. The first target battery compartment is a battery compartment with a low-power charging demand or a battery compartment that occupies multiple charging modules.

[0016] In a possible implementation manner, the method further includes:

[0018] If there is still the in-station charging demand when the out-station charging is completed, control the charging modules released after the out-station charging is completed to be used for in-station charging.

[0019] In a possible implementation manner, the method further includes:

[0020] If the second target battery compartment is converted from a high-power charging demand to a low-power charging demand and there is still the out-station charging demand, control the second target battery compartment to release some charging modules, and use the some charging modules for out-station charging.

[0021] In a possible implementation, the method further includes:

[0022] Obtaining the number of available batteries in the charging and swapping station;

[0023] If the number of available batteries is greater than or equal to a preset quantity threshold and there is no charging demand for the off-station charging piles, obtaining charging parameters;

[0024] If the charging parameters meet the preset conditions, controlling the charging module to perform slow charging on the unavailable batteries in the charging and swapping station.

[0033] A control unit, configured to allocate the charging module by using the control strategy.

[0034] In a possible implementation, the determining unit is specifically configured to, if both the off-station charging demand and the on-station charging demand exist, determine a control strategy according to the principle that the priority of the on-station charging demand is higher than that of the off-station charging demand. The control strategy is used to ensure that at least one charging module is allocated to the off-station charging pile with the off-station charging demand when the on-station charging demand is satisfied; if the on-station charging demand exists and the on-station charging demand includes a high-power charging demand and a low-power charging demand, determine a control strategy according to the principle that the priority of the high-power charging demand is higher than that of the low-power charging demand. The control strategy is used to allocate a first number of charging modules to the on-station battery bin with the high-power charging demand, and the first number of charging modules can meet the high-power charging demand of the on-station battery bin; if the on-station battery bin includes a first battery bin and a second battery bin and both the first battery bin and the second battery bin have a high-power charging demand, determine a control strategy according to the SOC of the batteries in the first battery bin and the SOC of the batteries in the second battery bin.

The first target battery bin is a battery bin with a low-power charging demand or a battery bin that occupies multiple charging modules.

[0036] In a possible implementation, the control unit is further configured to, if the off-station charging demand still exists when the on-station charging is completed, control the charging modules released after the on-station charging is completed to be used for off-station charging; if the on-station charging demand still exists when the off-station charging is completed, control the charging modules released after the off-station charging is completed to be used for on-station charging.

[0037] In a possible implementation, the control unit is further configured to, if the second target battery bin is converted from a high-power charging demand to a low-power charging demand and the off-station charging demand still exists, control the second target battery bin to release some charging modules and use the some charging modules for off-station charging.

[0051] To make the above objects, features, and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0052] To achieve greater utilization of the idle charging resources within the station and improve the energy replenishment capacity of the charging and swapping station, for the charging module that integrates off-station charging piles and in-station battery compartments, the present application will determine the control strategy matching the current charging environment according to the charging requirements of the off-station charging piles and the charging requirements of the in-station battery compartments, so as to allocate the charging modules using this control strategy, so that under the condition of meeting the in-station charging requirements, the maximum number of idle charging modules can be allocated to the off-station charging piles.

[0053] Among them, the composition structure of the charging and swapping station adapted to the solution of the present application is as Figure 1 shown. The charging and swapping station may include multiple battery compartments A1 - An, multiple off-station charging piles P1 - Pm, and multiple charging modules C1 - Cn + m. Among them, the charging modules can be flexibly allocated to the battery compartments or off-station charging piles, without forming a one-to-one binding relationship with the battery compartments. It should be noted that the number of charging modules can be deployed according to the actual application situation, Figure 1 only for illustration as an example.

[0054] The most basic service of the charging and swapping station is to provide battery swapping service. Therefore, it is the most basic prerequisite for the entire charging and swapping station to hold available batteries. When there is a high-power charging demand within the station, it indicates that the in-station service capacity is insufficient or about to be insufficient. Therefore, the priority of the high-power charging demand within the station is higher than that of the low-power charging demand within the station. That is, more charging modules are allocated to the battery compartments with high-power charging demands within the station to charge the battery packs. In addition, the main purpose of the off-station charging piles connected to the charging and swapping station is to maximize the utilization of the idle resources within the station. Therefore, regardless of whether there is a high-power charging demand or a low-power charging demand within the station, its priority is always higher than the charging demand of the off-station charging piles. At the same time, when there is a charging demand (high-power or low-power) for the off-station charging piles, at least one charging module is allocated to the off-station charging piles with charging demands to ensure that the off-station charging piles can work, thereby ensuring the experience of users using the off-station charging piles. That is, a basic condition that the control strategy in the present application needs to meet is that when there is a charging demand for the off-station charging piles, at least one charging module is allocated to the off-station charging piles with charging demands.

[0055] Based on the above principle, the present application provides a control method for a charging and swapping station. For easy understanding, it will be described below in conjunction with the accompanying drawings.

[0056] See Figure 2 , this figure is a flowchart of a control method for a charging and swapping station provided by an embodiment of the present application, as Figure 2As shown, the method includes:

[0057] S201: Obtain the in-station charging demand of the in-station battery compartment and the out-station charging demand of the out-station charging pile.

[0058] In this embodiment, to achieve the maximum utilization of the charging module, when allocating the charging module, obtain the charging demands of each in-station battery compartment and each out-station charging pile in the charging and swapping station. That is, determine whether the in-station battery compartment and the out-station charging pile have charging demands.

[0059] Among them, when the in-station battery compartment or the out-station charging pile has a charging demand, the charging demand can be divided into two types: high-power charging demand and low-power charging demand. Specifically, it can be divided into in-station battery compartment high-power charging demand, in-station battery compartment low-power charging demand, out-station charging pile high-power charging demand, and out-station charging pile low-power charging demand. Among them, the battery management system of the in-station battery or the battery management system on the out-station vehicle can determine high-power charging or low-power charging according to the current state of the battery.

[0060] S202: Determine a control strategy according to the in-station charging demand and the out-station charging demand, and use the control strategy to allocate the charging module.

[0061] In this embodiment, when obtaining the in-station charging demand of the in-station battery compartment and the out-station charging demand of the out-station charging pile, a control strategy for the charging module can be determined according to the types of the in-station charging demand and the out-station charging demand. Among them, the control strategy is used to allocate the maximum number of idle charging modules to the out-station charging pile under the condition of meeting the in-station charging demand, so as to achieve the maximum utilization of the idle charging resources.

[0062] Among them, determining the control strategy according to the in-station charging demand and the out-station charging demand can be divided into the following situations:

[0063] (1) If there are both out-station charging demands and in-station charging demands at the same time, determine the control strategy according to the principle that the priority of the in-station charging demand is higher than that of the out-station charging demand. This control strategy is used to ensure that at least one charging module is allocated to the out-station charging pile with an out-station charging demand under the condition of meeting the in-station charging demand.

[0064] In this embodiment, for the in-station batteries and off-station charging piles of the charging and swapping station, they are essentially service units capable of generating energy replenishment. In the actual application scenario, from the perspective of users, a group of in-station batteries or a single charging pile is considered as a single service unit with the ability to replenish energy. Therefore, a single service unit should be kept in a service-capable state as much as possible. Based on this, when the off-station charging pile has a charging demand, at least one charging module is allocated to the off-station charging pile to enable it to have service capabilities. It should be noted that when the in-station charging demand is a high-power charging demand, the control strategy is used to meet the in-station high-power charging demand; when the in-station charging demand is a low-power charging demand, the control strategy is used to meet the in-station low-power charging demand.

[0065] In actual applications, the time when the in-station battery storage generates a charging demand and the time when the off-station charging pile generates a charging demand may have a sequence. Based on the different occurrence time points, there may be a situation where the occupied charging modules need to be released and used for other charging scenarios. Among them, the release of the charging module includes active release and passive release. Active release means that after the in-station battery storage or the off-station charging pile completes charging or the charging demand decreases (the charging demand decrease means changing from high-power charging to low-power charging), the charging module is actively released; passive release means that the charging and swapping station controls the in-station battery storage or the off-station charging pile that is occupying the charging module to release the charging module to meet the high-priority charging demand.

[0066] Specifically, it may include the following application scenarios:

[0067] 1. If the off-station charging demand occurs earlier than the in-station charging demand and the remaining charging modules cannot meet the in-station charging demand, then control the off-station charging pile to release the charging module and use the released charging module for in-station charging.

[0068] In this embodiment, when the in-station charging demand occurs later than the off-station charging demand and the number of charging modules required for the in-station charging demand is greater than the current remaining charging modules, based on the in-station charging priority being higher than the off-station charging priority, control the off-station charging pile to release some charging modules so that the released charging modules can be used for in-station charging. It should be noted that when controlling the off-station charging pile to release the charging module, at least ensure that there is one charging module occupied by the off-station charging pile with a charging demand, so as to ensure the service capabilities of the off-station charging pile and the experience of users using the off-station charging pile. Among them, the in-station charging demand can be a high-power charging demand or a low-power charging demand. No matter which type of charging demand it is, as long as the current remaining charging modules cannot meet the in-station charging, control the off-station charging pile to release the charging module.

[0069] Among them, to maximize the utilization of charging resources, when there is still an off-station charging demand after charging is completed within the station, the charging modules released after charging is completed within the station are controlled for off-station charging; or, when there is still an on-station charging demand after off-station charging is completed, the charging modules released after off-station charging is completed are controlled for on-station charging; or, if the second target battery compartment with a charging demand changes from a high-power charging demand to a low-power charging demand and there is still an off-station charging demand, the second target battery compartment is controlled to release some charging modules, and some charging modules are used for off-station charging.

[0070] Among them, the number of charging modules released by the second target battery compartment can be determined by the Battery Management System (BMS) of the batteries loaded in the second target battery compartment. For example, when the batteries in the second target battery compartment are charged at high power, the BMS determines that 3 charging modules are required to meet the high-power charging; when it changes to low-power charging, the BMS determines that 1 charging module is required to meet the charging demand, and then 2 charging modules can be released.

[0071] For ease of understanding, the following will be combined with Figure 3 for illustration. As Figure 3 shown, the charging and swapping station includes 3 battery compartments A1 - A3, one charging pile P1, and 4 charging modules C1 - C4.

[0072] Scenario Embodiment One : When the off-station charging pile is in use and there is a high-power charging demand within the station (at least ensuring that a single charging module provides power output to the off-station charging pile)

[0073] 1) P1 has a charging demand, requiring 4 charging modules, and C4, C3, C2, and C1 have been enabled to charge P1;

[0074] 2) When there is a high-power charging demand in A1 within the station (for example, in a scenario where the current remaining available battery quantity cannot ensure the ability to provide battery swapping service), requiring 4 charging modules, while ensuring that P1 can be served, any 3 charging modules are controlled to be released passively and charge A1 (for example, releasing C1, C2, and C3);

[0075] 3) If the charging of P1 ends, C4 is actively released; if A1 is still in a high-power charging demand, C4 is used to charge A1;

[0076] 4) If the charging of A1 ends, C1, C2, and C3 are actively released; if P1 has a high-power charging demand, C1 - C3 can be used to charge P1;

[0077] 5) If the charging demand of A1 decreases (from high-power charging to low-power charging), then actively release one or two of the charging modules C1, C2, and C3; if P1 has a high-power charging demand, the released charging module(s) can be used to charge P1.

[0078] Scenario Embodiment Two : During the use of off-station charging piles, there is a low-power charging demand in the station (the in-station charging demand has a higher priority than the off-station charging demand)

[0079] 1) P1 has a high-power charging demand, requiring 4 charging modules, and C4, C3, C2, and C1 are enabled and charging P1;

[0080] 2) A1 has a low-power charging demand, requiring 1 module, and there are no remaining charging modules at present, so control any one charging module (such as C1) to passively release and charge A1;

[0081] 3) If the charging of A1 ends, then actively release C1; if P1 is still in a high-power charging demand, then control C1 to charge P1.

[0082] 2. If the in-station charging demand occurs earlier than the off-station charging demand and there are no remaining charging modules for off-station charging, control the first target battery compartment to release one charging module and use the released charging module for off-station charging. Among them, the first target battery compartment is the battery compartment with a low-power charging demand or the battery compartment that occupies multiple charging modules.

[0083] In this embodiment, when the time when the off-station charging pile generates a charging demand is later than the time when the in-station battery compartment generates a charging demand and there are no remaining charging modules for the off-station charging pile, control the first target battery compartment to release one charging module and use this charging module for off-station charging. Since the in-station high-power charging has a higher priority than the in-station low-power charging, when there is both high-power charging and low-power charging in the station, the battery compartment with low-power charging is preferentially controlled to release the charging module. Or, when there is only high-power charging or low-power charging in the station, control the battery compartment that occupies more charging modules to release the charging module.

[0084] It should be noted that if the in-station charging demand occurs earlier than the off-station charging demand and there are remaining charging modules, directly use the remaining charging modules for off-station charging.

[0085] To maximize the utilization of charging resources, if there is still an off-site charging demand when charging in the station is completed, control the charging modules released after charging in the station to be used for off-site charging; or, if there is still an on-site charging demand when off-site charging is completed, control the charging modules released after off-site charging to be used for on-site charging; or, if the second target battery compartment switches from a high-power charging demand to a low-power charging demand and there is still an off-site charging demand, then control the second target battery compartment to release some charging modules and use some of the charging modules for off-site charging.

[0086] For ease of understanding, take Figure 3 as an example for illustration:

[0087] Scenario Embodiment Three : High-power charging is in progress in the station, and there is a charging demand at the off-site charging pile (at least ensure that a single charging module provides power output to the off-site charging pile)

[0088] 1) A1 has a high-power charging demand, requiring 4 charging modules. C1, C2, C3, and C4 have been enabled and are charging A1;

[0089] 2) P1 has a charging demand, requiring 4 charging modules. Any one charging module (such as C4) is released passively and charges P1;

[0090] 3) If the charging of A1 ends, then C1, C2, and C3 are released actively; if P1 still has a high-power charging demand, then C1, C2, and C3 can be used to charge P1;

[0091] 4) If the charging demand of A1 decreases (changes from high-power charging to low-power charging), then 1 or 2 charging modules among C1, C2, and C3 are released actively; if P1 has a high-power charging demand, then the released charging modules can be used to charge P1;

[0092] 5) If the charging of P1 ends, then C4 is released actively; if A1 is still in high-power charging, then C4 is used to charge A1.

[0093] Scenario Embodiment Four : Low-power charging is in progress in the station, and there is a charging demand at the off-site charging pile (the on-site charging demand has a higher priority than the off-site high-power switching charging demand)

[0094] 1) A1, A2, and A3 have low-power charging demands, each requiring 1 charging module. C1, C2, and C3 have been enabled respectively and are charging A1, A2, and A3;

[0095] 2) P1 has a charging demand, requiring 4 charging modules. C4 is enabled and charges P1; C1, C2, and C3 are not released;

[0096] 3) After A1, A2, and A3 finish charging, they actively release C1, C2, and C3 and charge P1.

[0097] (2) If there is an in-station charging demand and the in-station charging demand includes a high-power charging demand and a low-power charging demand, then according to the principle that the priority of the high-power charging demand is higher than that of the low-power charging demand, a control strategy is determined. This control strategy is used to allocate a first number of charging modules to the in-station battery compartments with high-power charging demands, and the first number of charging modules can meet the high-power charging demands of the in-station battery compartments.

[0098] In this embodiment, when there is both high-power charging and low-power charging in the in-station battery compartments, then according to the principle that the priority of the in-station high-power charging demand is higher than that of the in-station low-power charging demand, a control strategy is determined. This control strategy is used to allocate a first number of charging modules to the in-station battery compartments with high-power charging demands, and the first number of charging modules can meet the high-power charging demands of the in-station battery compartments. In this application scenario, the sequence of events is not distinguished. If the high-power charging demand occurs later than the low-power charging demand and the currently remaining charging modules cannot meet the high-power charging demand, then the battery compartments in low-power charging are controlled to passively release the charging modules, and these charging modules are used for the off-station charging piles with high-power charging demands. Among them, the first number can be determined by the BMS of the battery.

[0099] It should be noted that in this application scenario, if there is also an off-station charging demand, then one charging module is allocated to the off-station charging pile to ensure the service capacity of the off-station charging pile.

[0100] For easy understanding, in combination with Figure 3 it is described as follows:

[0101] Scenario Embodiment Five : There is a battery compartment in the station that is already charging at low power, and then there is a high-power charging demand for another battery compartment (the priority of the in-station high-power charging demand is higher than that of the in-station low-power charging demand)

[0102] 1) A1 has a low-power charging demand, and the demand is for 1 module. C1 has been enabled and is charging A1.

[0103] 2) A2 has a high-power charging demand, and the demand is for 4 modules; C2, C3, and C4 are preferentially enabled and charge A2; the charging demand of A2 is not met, and C1 is passively released and charges A2.

[0104] 3) If the charging demand of A2 decreases, then C1 is actively released and A1 is charged.

[0105] (3) If the on-site battery compartment includes a first battery compartment and a second battery compartment, and both the first battery compartment and the second battery compartment have high-power charging requirements, a control strategy is determined based on the SOC of the batteries in the first battery compartment and the SOC of the batteries in the second battery compartment. This control strategy is used to allocate a second number of the charging modules to the battery compartment where the battery with a high SOC is located, and the second number of charging modules can meet the high-power charging requirements of the battery with a high SOC.

[0106] In this embodiment, the on-site battery pack is used as a service unit, and the overall service capacity is given priority over the service capacity of a single battery. When multiple batteries simultaneously generate high-power charging requirements, it indicates that the on-site battery swapping service capacity is insufficient or about to be insufficient. To ensure the battery swapping service of the charging and swapping station, the control strategy will give priority to meeting the charging requirements of a single battery. To enable the battery to have service capacity as soon as possible, charging will be prioritized for the battery with a high SOC. Specifically, the control strategy is used to allocate a second number of charging modules to the battery with a high SOC, and the second number of charging modules can meet the charging requirements of the battery with a high SOC. Among them, the second number can be determined by the BMS of the battery with a high SOC.

[0107] For ease of understanding, combined with Figure 3 it is described as follows:

[0108] Scenario Example 6: There is a battery compartment in the station that is already charging at high power, and another battery compartment in the station has a high-power charging requirement (when high-power requirements in the station occur simultaneously, the battery with a higher SOC is given priority to be satisfied).

[0109] 1) A1 has a high-power charging requirement, and the requirement is 4 modules; C1, C2, C3, and C4 have been enabled and are charging A1;

[0110] 2) If A2 has a high-power charging requirement, and the requirement is 4 modules; the real-time SOC of A2 is higher than that of A1; C1, C2, C3, and C4 are released passively and charge A2;

[0111] 3) If A2 has a high-power charging requirement, and the requirement is 2 modules; the real-time SOC of A2 is higher than that of A1; any two modules (such as C1 and C4) are released passively and charge A2;

[0112] 4) If the charging requirement of A2 decreases or the charging ends, the occupied modules are released actively and charge A1.

[0113] In a specific implementation, in order to protect the batteries in the station and extend the service life of the batteries in the station, when the available batteries in the station are in excess of demand and there is no demand for charging at the charging piles outside the station, the unavailable batteries are flexibly slow-charged. Specifically, the number of available batteries in the charging and swapping station is obtained; if the number of available batteries is greater than or equal to a preset number threshold and there is no demand for charging at the charging piles outside the station, the charging parameters are obtained; if the charging parameters meet the preset conditions, the charging module is controlled to perform slow charging on the unavailable batteries in the charging and swapping station. Among them, the number of available batteries is greater than or equal to the preset number threshold, indicating that the current available batteries in the charging and swapping station are in excess of demand. The charging parameters may include electricity prices, the time required for charging, etc. When the charging parameters meet the preset conditions, indicating that the current charging environment is suitable for flexible full charging of the batteries, the charging module is controlled to fully charge the unavailable batteries. Among them, the preset conditions can be set according to actual conditions. For example, due to different electricity charges in different time periods, the preset condition is that the electricity price is the lowest price, and the preset number threshold can be determined based on the actual needs of the user for the charging and swapping station.

[0114] From the foregoing, it can be seen that the control method provided in the embodiment of the present application can achieve the following effects:

[0115] 1) When there is a demand for off-station charging, the low-power charging demand of the off-station charging pile is always met to ensure the service capacity of the off-station service unit;

[0116] 2) When the available batteries in the station are in short supply, high-power switching and charging of batteries with relatively higher power should be performed as much as possible to make them available as soon as possible to ensure the service capacity of the service units in the station;

[0117] 3) When the available batteries in the station are in a situation where the supply is greater than or equal to the demand, the idle charging modules should be applied to the charging piles outside the station as much as possible to ensure the service capacity of the service unit outside the station;

[0118] 4) When the available battery supply in the station is greater than or equal to the demand and there is no demand for charging at the charging pile outside the station, the unavailable battery can be flexibly slow-charged to protect assets and extend the service unit life cycle.

[0119] Based on the above method embodiment, the present application embodiment also provides a data transmission device, which will be described below in conjunction with the accompanying drawings.
