Description

Technical Field

[0001] The present application relates to the technical field of power battery charging control, and in particular to a charging control method, system, equipment and medium for a battery swap station. Background Art

[0002] Typically, the charging equipment at a battery swap station uses multiple charging modules consisting of power modules and control circuits of the same specifications. The power modules are usually not shared between modules. When a module's battery is charging, as the state of charge increases, the charging demand power decreases and the power module enters a working range below half load, reducing the efficiency of the power module and increasing power loss. When a module has no charging demand, the power module will be idle and cannot be used by other charging modules, resulting in low utilization of the power module and cost waste.

[0003] Another type of charging equipment in a battery swap station adds a power distribution unit, so that the power modules configured in the system are shared with multiple batteries. When the charging power demand is reduced, some power modules can be cut out for use by other batteries. However, the newly added power distribution unit is expensive and has a high failure rate. If the number of batteries in the battery swap station is large, multiple power modules are required, which makes the power distribution unit have more input and output nodes, high hardware investment cost, and complex control logic. When a single node inside the power distribution unit fails, the entire power distribution unit cannot work normally, which in turn affects the operating efficiency of the entire battery swap station.

[0045] The following describes in detail the charging control method, system, device and medium of the battery swap station according to the embodiments of the present application in conjunction with the accompanying drawings.

[0046] In the implementation environment of the application embodiment, a personal computing device, such as a computer, can control the high-power module to charge the power battery; based on the charging state of the power battery, determine whether the charging demand of the power battery has dropped to a predetermined index; when the charging demand of the power battery has dropped to the predetermined index, switch to the low-power module to charge the power battery until the charging exit condition is met.

[0047] Alternatively, it can also be implemented by a server, for example: the personal computing device sends a request to the server, and the server controls the high-power module to charge the power battery; according to the charging state of the power battery, it is determined whether the charging demand of the power battery has dropped to a predetermined index; when the charging demand of the power battery has dropped to the predetermined index, it switches to the low-power module to charge the power battery until the charging exit condition is met, and finally, the result is returned to the personal computing device.

[0048] Among them, the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), as well as big data and artificial intelligence platforms.

[0049] Before describing the charging control method of a battery swap station according to an embodiment of the present application, the battery swap station is first described. Figure 1 As shown, the battery swap station includes a charging device 110, a battery rack 120, a battery swap device 130, and a station control host 140, etc., wherein the charging device 110 includes at least a high-power module 111 and a low-power module 112. Of course, the charging device 110 may also include a control unit 113, and the battery rack 120 may be provided with a high-power compartment 121, a low-power compartment 122, and a battery-to-be-swapped compartment 123, etc. Figure 2 As shown, combined with Figure 1 , showing that the battery 120 includes multiple compartments, such as: a battery replacement compartment 123, a low power compartment 122, and a high power compartment 111. Among them, when the power battery is in the low power compartment and the high power compartment, it can be charged by the high power module and the low power module. The method implemented in this application can be implemented by the station control host for related control.

[0050] Combination Figure 1As shown, reference numeral 1 indicates the information interaction between the power module and the control unit. The control unit can realize functions such as controlling the startup and shutdown of the power module and controlling the output size of the power module according to battery requirements or strategies; reference numeral 2 indicates the communication between the control unit and the battery pack BMS (i.e., the battery management system of the power battery, Battery Monitoring and Management System), which can adopt the CAN (Controller Area Network) communication protocol for communication, which is used for status monitoring and charging interaction after the power battery is connected; reference numeral 3 indicates the communication between the charging equipment and the station control host of the battery swap station, which can realize the uploading of data such as the charging equipment status, battery pack (power battery) charging status, charging / standby, and the execution of control instructions of the station control host; reference numeral 4 indicates the communication between the station control host and the battery swapping equipment, which realizes the commands for controlling mechanical battery swapping and battery movement, and monitors the status of the battery swapping equipment; reference numeral 5 indicates that the battery swapping equipment controls the movement of the power battery and the plugging and unplugging of the power battery connector.

[0051] It should be noted that Figure 2 The low-power warehouse, high-power warehouse and warehouse to be replaced are only distinguished according to the function of the warehouse. In other examples, there may also be multiple warehouses with the same function.

[0052] Figure 3 FIG. 1 is a flow chart of a charging control method of a battery swap station according to an embodiment of the present application. Figure 3 As shown, according to an embodiment of the present application, a charging control method of a battery swap station includes the following steps:

[0053] S101: Control the high power module to charge the power battery.

[0054] like Figure 2 As shown, the station control host controls the battery exchange equipment to put the power battery that needs to be charged in the vehicle into the high-power compartment, and then waits for charging to be ready. The station control host controls the high-power module of the charging equipment to charge the power battery in the high-power compartment.

[0055] S102: judging, according to the charging state of the power battery, whether the charging demand of the power battery has dropped to a predetermined index.

[0056] In one embodiment of the present application, judging whether the charging demand of the power battery has dropped to a predetermined index according to the charging state of the power battery includes: obtaining the charge state of the power battery according to the charging state of the power battery; judging whether the charge state has reached a predetermined threshold; if the charge state has reached the predetermined threshold, judging that the charging demand of the power battery has dropped to the predetermined index.

[0057] For example, if the predetermined threshold is 0.8, when the power battery is charged through the high power module, when the power battery's state of charge (SOC), that is, the ratio of the remaining power of the power battery to the fully charged power, reaches 80%, it is determined that the charging demand of the power battery has dropped to the predetermined index.

[0058] S103: When the charging demand of the power battery drops to the predetermined index, switching to the low-power module to charge the power battery until a charging exit condition is met.

[0059] In one embodiment, when the charging demand of the power battery drops to the predetermined index, switching to the low-power module to charge the power battery until the charging exit condition is reached, including: when the charging demand of the power battery drops to the predetermined index, controlling the battery exchange equipment to move the power battery from the high-power compartment to the low-power compartment, wherein the high-power compartment corresponds to the high-power module, and the low-power compartment corresponds to the low-power module; controlling the low-power module to charge the power battery until the charging exit condition is reached, thereby completing the charging process of the power battery.

[0060] In the above example, after completing the charging process of the power battery, it also includes: controlling the battery replacement equipment to move the power battery from the low-power compartment to the compartment to be replaced.

[0061] like Figure 4A and Figure 4B As shown, combined with Figure 2When the vehicle replaces the power battery that needs to be charged at the battery swap station, the station control host controls the battery swap device to move the replaced power battery, and the battery swap device puts the power battery into the high-power compartment. After the electrical connector is physically connected successfully, the charging device reads the battery information of the power battery and uploads the battery information and the charging device information to the station control host. The station control host determines whether the charging start conditions are met. If the charging start conditions are met, a charging instruction is sent to the charging device, and the charging device starts charging and charges the power battery through the high-power module. During this process, the charging device and the power battery interact with each other, that is, the power battery and the charger (charging device) interact with charging data. The charging device uploads the charging data during the charging process to the station control host, and the station control host monitors the status of the charger and the battery during charging. When it is determined that the charging demand of the power battery has dropped to the predetermined index, that is, the battery demand has dropped to the set threshold, a stop charging instruction is sent to the charging device, and the charging device controls the high-power module to stop charging the power battery. Next, the station control host controls the battery swapping device to move the power battery, and the battery swapping device places the power battery into the low-power compartment. After the connection is ready and charging is ready, the station control host determines whether the conditions for starting charging are met. If the conditions for starting charging are met, a charging instruction is sent to the charging device. The charging device controls the low-power module to continue charging the power battery until the shutdown conditions are met, that is: after the charging exit conditions are met, the low-power module is controlled to stop charging the power battery.

[0062] When the power battery is fully charged, the station control host controls the battery swapping device to move the power battery to the battery swapping compartment, and waits for the vehicle to arrive before swapping the battery for the vehicle. For example, if a new vehicle arrives and needs to use a battery, the station control host controls the battery swapping device to move the battery, and then the vehicle uses the charged power battery.

[0063] In this example, combined Figure 2 As shown, the charging device is connected to the battery rack and establishes a physical connection with the battery through the battery connector of each layer of the battery compartment of the battery rack. The battery compartment is divided into a high-power compartment and a low-power compartment according to the power size configured by the corresponding charging device. An additional battery compartment without a charging function is used as a battery replacement compartment, which only communicates with the charging device for data uploading and battery storage. The number of high-power compartments, low-power compartments, and battery replacement compartments can be configured through the charging equipment according to the application scenarios and operating capabilities of the actual battery replacement station. The rated output power of the high-power compartment and the low-power compartment is reasonably selected according to the battery charging characteristics. In other words, the rated output power of the high-power module and the rated output power of the low-power module are pre-set according to the charging characteristics of the power battery.

[0064] Since each charging module in the charging device is independent, when a single component fails, the charging function of the corresponding battery compartment fails, and it has no effect on the charging functions of other battery compartments. The battery can be moved to other valid compartments. Compared with the charging device using a power distribution unit in the related technology, since there are more control nodes and multiple battery compartments are connected, the failure of a single component often affects the charging functions of multiple battery compartments. Therefore, the embodiments of the present application can reduce the charging impact range when the charging device fails, and effectively improve the reliability of charging.

[0065] In another embodiment, when the charging demand of the power battery drops to the predetermined index, the low-power module is switched to charge the power battery until the charging exit condition is reached, including: fixing the charging position of the power battery unchanged, disconnecting the connection between the high-power module and the power battery; switching to the low-power module to connect with the power battery; controlling the low-power module to charge the power battery until the charging exit condition is reached, and completing the charging process of the power battery. For example: the conversion between the high-power module and the low-power module is achieved by fixing the position of the power battery and connecting the mobile charging device to the power battery.

[0066] In one or more of the above-mentioned embodiments, the charging exit condition includes: the power battery is fully charged; or, a charging exit instruction is received.

[0067] According to the charging control method of the battery swap station in the embodiment of the present application, the high-power module is first controlled to charge the replaced power battery, and then, according to the real-time charging status of the power battery, after judging that the charging demand of the power battery has dropped to a predetermined index, the low-power module is switched to charge the power battery. As a result, the power battery can be connected and charged with different power modules without the need to develop an additional power distribution unit, thereby effectively reducing the power loss of the power module and having the advantage of low cost compared to the prior art.

[0068] Figure 5 1 is a structural block diagram of a charging control system of a battery swap station according to an embodiment of the present application. Figure 5 As shown, according to an embodiment of the present application, a charging control system of a battery swap station includes: a high-power module control unit 510, a judgment module 520 and a low-power module control unit 530, wherein:

[0069] A high power module control unit 510, used to control the high power module to charge the power battery;

[0070] A judgment module 520 is used to judge whether the charging demand of the power battery is reduced to a predetermined index according to the charging state of the power battery;

[0071] The low power module control unit 530 is used to switch to the low power module to charge the power battery when the charging demand of the power battery drops to the predetermined index, until the charging exit condition is reached.

[0072] According to the charging control method of the battery swap station in the embodiment of the present application, the high-power module is first controlled to charge the replaced power battery, and then, according to the real-time charging status of the power battery, after judging that the charging demand of the power battery has dropped to a predetermined index, the low-power module is switched to charge the power battery. As a result, the power battery can be connected and charged with different power modules without the need to develop an additional power distribution unit, thereby effectively reducing the power loss of the power module and having the advantage of low cost compared to the prior art.
