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, device and medium for a battery swap station. BACKGROUND

[0002] Generally, the charging equipment of a battery swap station adopts multiple charging modules composed of power modules and control circuits of the same specification. The power modules between the modules are usually not shared. When a module battery is charging and the state of charge increases, the charging demand power decreases, and the power module enters the working interval below half load, which reduces the efficiency of the power module and increases the power loss. When a module has no charging demand, the power module is idle and cannot be used by other charging modules, resulting in low utilization rate of the power module and cost waste.

[0003] Another charging equipment of a battery swap station increases a power distribution unit, so that the power modules configured by the system are shared by multiple batteries. When the charging demand power decreases, part of the power modules can be cut out for use by other batteries. However, the newly added power distribution unit has high cost and high failure rate. If the number of batteries in the battery swap station is configured to be relatively large, multiple power modules need to be matched, so that the input and output nodes of the power distribution unit are relatively large, the hardware investment cost is high, and the control logic is complex. When a single node inside the power distribution unit fails, the entire power distribution unit cannot work normally, thereby affecting the operation efficiency of the entire battery swap station.

[0049] Before describing the charging control method of the battery swap station according to an embodiment of the present application, the battery swap station is first described, as shown in Figure 1 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 one high-power module 111 and one low-power module 112, of course, the charging device 110 can also include a control unit 113, and the battery rack 120 can be provided with a high-power bin 121, a low-power bin 122, and a battery replacement bin 123, etc. As shown in Figure 2 As shown in Figure 1 , it shows that the battery 120 includes multiple bins, such as the battery replacement bin 123, the low-power bin 122, and the high-power bin 111. Among them, when the power battery is in the low-power bin and the high-power bin, it can be charged by the high-power module and the low-power module. The method implemented by the present application can be controlled and implemented by the station control host.

[0050] In combination with Figure 1As shown, the number 1 is the information interaction between the power module and the control unit, the control unit can realize the functions of controlling the start and shutdown of the power module, controlling the output size of the power module according to the battery demand or strategy, etc.; the number 2 is 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 use the CAN (Controller Area Network) communication protocol for communication, for state monitoring and charging interaction after the power battery is connected; the number 3 is the communication between the charging device and the station control host of the battery swap station, which can realize the functions of uploading the data of the charging device state, the battery pack (power battery) charging state, charging / standby, executing the control instructions of the station control host, etc.; the number 4 is the communication between the station control host and the battery swap device, which realizes the command of controlling the mechanical battery swap and the movement of the battery, and monitors the state of the battery swap device; the number 5 is the control of the movement of the power battery and the plugging of the power battery connector by the battery swap device.

[0051] It should be noted that, Figure 2 The low-power bin, the high-power bin and the battery replacement bin described in the above are only distinguished according to the functions of the bins, and in other examples, a plurality of bins with the same function can also be provided.

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

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

[0054] As Figure 2 shown, the station control host controls the battery swap device to put the power battery that needs to be charged and is replaced from the vehicle into the high-power bin, and then waits until the charging is ready, after which the station control host controls the high-power module of the charging device to charge the power battery in the high-power bin.

[0055] S102: Determine whether the charging demand of the power battery decreases to a predetermined index according to the charging state of the power battery.

[0056] In an embodiment of the present application, determining whether the charging demand of the power battery decreases to a predetermined index according to the charging state of the power battery includes: obtaining the state of charge of the power battery according to the charging state of the power battery; determining whether the state of charge reaches a predetermined threshold; and if the state of charge reaches the predetermined threshold, determining that the charging demand of the power battery decreases to the predetermined index.

[0057] For example, when the predetermined threshold is 0.8, if the state of charge (SOC) of the power battery, i.e., the ratio of the remaining capacity of the power battery to the full capacity, reaches 80% during the charging process of the power battery by the high-power module, it is determined that the charging demand of the power battery decreases to the predetermined index

[0058] S103: When the charging demand of the power battery decreases to the predetermined index, switch to the low-power module to charge the power battery until the charging exit condition is reached.

[0059] In one embodiment, when the charging demand of the power battery decreases to the predetermined index, switching to the low-power module to charge the power battery until the charging exit condition is reached includes: when the charging demand of the power battery decreases to the predetermined index, controlling the battery swap device to move the power battery from the high-power bin to the low-power bin, wherein the high-power bin corresponds to the high-power module, and the low-power bin corresponds to the low-power module; and 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 the charging process of the power battery is completed, the method further includes: controlling the battery swap device to move the power battery from the low-power bin to the standby battery swap bin.

[0061] As shown in Figure 4A and Figure 4B shown, and in combination with Figure 2When the vehicle replaces the power battery that needs to be charged at the battery swap station, the replaced power battery is moved by the station control host controlled battery swap equipment, and the battery swap equipment puts the power battery into the high-power bin. After the physical connection of the electric connector is successful, 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 judges whether the charging start condition is reached, and if the charging start condition is reached, the charging instruction is issued to the charging device, the charging device starts charging, and the high-power module charges the power battery. During this process, the charging device and the power battery perform a charging interaction process, that is, the power battery and the charger (charging device) charge data interaction. The charging device uploads the charging data in the charging process to the station control host, and the station control host monitors the state of the charger and the battery charging. When it is judged that the charging demand of the power battery decreases to the predetermined index, that is, the battery needs to decrease to the set threshold, the stop charging instruction is sent to the charging device, and the charging device controls the high-power module to stop charging the power battery. Then, the station control host controls the battery swap equipment to move the power battery, and the battery swap equipment puts the power battery into the low-power bin. After the connection is ready and the charging is ready, the station control host judges whether the charging start condition is reached, and if the charging start condition is reached, the charging instruction is sent to the charging device, and the charging device controls the low-power module to continue charging the power battery until the stop condition is reached, that is, the charging exit condition is reached, and the low-power module is controlled to stop charging the power battery.

[0062] When the power battery charging is completed, the station control host controls the battery swap equipment to move the power battery to the battery replacement waiting bin, and waits for the vehicle to arrive to replace the battery. For example, a new vehicle arrives to take the battery, and the station control host controls the battery swap equipment to move the battery, and then the vehicle takes the fully charged power battery.

[0063] In this example, in combination with Figure 2 As shown in the figure, the charging device is connected with the battery rack, and a physical connection is established with the battery through the battery connector of each layer of the battery bin of the battery rack. The battery bin is divided into a high-power bin and a low-power bin according to the power size configured by the corresponding charging device, and a battery bin without charging function is additionally provided as a battery replacement waiting bin, which only communicates with the charging device for data uploading and battery storage. The number of high-power bins, low-power bins and battery replacement waiting bins can be configured by the charging device according to the application scene and operation capacity of the actual battery swap station. The rated output power of the high-power bin and the low-power bin is reasonably selected according to the battery charging characteristics, that is, 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 power battery charging characteristics.

[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 the charging function of other battery compartments is not affected. The battery can be moved to other effective compartments. Compared with the charging device using a power distribution unit in the related art, since there are more control nodes and multiple battery compartments are connected, when a single component fails, the charging function of multiple battery compartments is often affected. Therefore, the embodiments of the present application can reduce the charging influence 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 decreases 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; switch to connect the low-power module and the power battery; control the low-power module to charge the power battery until the charging exit condition is reached, complete the charging process of the power battery. For example: by fixing the position of the power battery, the connection mode of the charging device and the power battery is changed to realize the conversion of the high-power module and the low-power module.

[0066] In one or more of the above 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, the high-power module is first controlled to charge the replaced power battery, and then the low-power module is switched to charge the power battery according to the real-time charging state of the power battery after the charging demand of the power battery decreases to the predetermined index. Therefore, the power battery can be connected and charged with different power modules without developing a power distribution unit, thereby effectively reducing the power loss of the power module and having the advantage of low cost compared with the prior art.

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

[0069] The high-power module control unit 510 is configured to control the high-power module to charge the power battery.

[0070] The judgment module 520 is configured to judge whether the charging demand of the power battery decreases to a predetermined index according to the charging state of the power battery.

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

[0072] According to the charging control method of the battery swap station, the high-power module is first controlled to charge the power battery, and then the low-power module is switched to charge the power battery according to the real-time charging state of the power battery. Therefore, the power battery can be connected and charged with different power modules without developing an additional power distribution unit, thereby effectively reducing the power loss of the power module and having the advantage of low cost compared with the prior art.
