Description

Technical Field

[0001] The present application relates to the field of vehicle battery replacement technology, and more specifically, to a control method, a control device and a battery replacement station in the field of vehicle battery replacement technology. Background Art

[0002] In order to achieve the effect of energy conservation and emission reduction, new energy vehicles such as electric vehicles are gradually becoming popular. Due to the limited energy density of electric vehicle batteries, the range is limited, and the charging time is long; therefore, battery swap stations are set up to provide users with battery swap services; battery swap stations can quickly solve the problem of electric vehicle energy replenishment by directly replacing fully charged batteries, effectively alleviating users' range anxiety.

[0003] However, the battery swap service of the battery swap station relies on the continuous power supply of the power grid; when there is a power supply abnormality, the battery swap station will immediately cut off power and will be unable to continue to provide battery swap services, which will in turn affect the user's battery swap operation.

[0004] Therefore, when the power supply of the battery swap station is abnormal, how to maintain the battery swap service of the battery swap station is an urgent problem to be solved. Summary of the invention

[0005] The present application provides a control method, a control device and a battery swap station. The method can maintain the battery swap service of the battery swap station when the power supply of the battery swap station is abnormal.

[0006] In a first aspect, a control method for a battery swap station is provided, the method comprising:

[0007] When it is detected that the power supply of the battery swap station is abnormal, the relay of the backup battery compartment in the battery swap station is controlled to close; wherein the battery compartment of the battery swap station includes the target battery compartment and the backup battery compartment;

[0008] Based on the backup battery in the backup battery compartment, power is supplied to the target component in the battery swap station so that the battery swap station can provide battery swap services; wherein the target component is used to control the normal operation of the battery swap station;

[0009] In response to a battery replacement instruction of the vehicle, a battery replacement service is provided to the vehicle based on a target component and a target battery in a target battery compartment.

[0010] In the above technical solution, when abnormal power supply of the battery swap station is detected, the backup battery is used to supply power to the target component by closing the relay of the backup battery position, which can ensure that the key components responsible for controlling the normal operation of the battery swap station can continue to work, so that the battery swap station can provide normal battery swap services for the vehicle; when receiving the battery swap command of the vehicle, the battery swap command is responded to, and the battery swap service is provided to the vehicle through the target component and the target battery position; it can avoid the overall paralysis of the battery swap station due to the abnormal main power supply, and ensure that the basic functions of the battery swap station are maintained; ensure that normal battery swap services can still be provided in the case of abnormal power supply of the battery swap station, so that the vehicle undergoing battery swap will not be terminated due to sudden power outage of the battery swap station, and the vehicle that has not started battery swap will not be unable to perform battery swap due to abnormal power supply of the battery swap station. In addition, this solution does not need to be equipped with an additional backup power supply. The original battery in the battery swap station can realize normal power supply when the power supply of the battery swap station is abnormal, which can reduce the configuration cost of the battery swap station.

[0011] In combination with the first aspect, in some possible implementations, the method further includes:

[0012] Obtain the power of each candidate battery in the target battery slot;

[0013] Determine a first candidate battery whose power level among the candidate batteries is greater than or equal to a first power level threshold as a target battery in the target battery compartment;

[0014] Based on the second candidate battery among the candidate batteries, the third candidate battery is charged so that the power of the third candidate battery is greater than or equal to the first power threshold; wherein the power of the second candidate battery and the third candidate battery is less than the first power threshold, and the power of the second candidate battery is less than the power of the third candidate battery.

[0015] In the above technical solution, the power of each candidate battery in the target battery compartment is obtained, and the first candidate battery with a power greater than or equal to the first power threshold is determined as an available battery; for batteries with a power less than the first power threshold, the second candidate battery with a lower power is used to charge the third candidate battery with a higher power, so that the power of the third candidate battery reaches the first power threshold, and the third candidate battery can be used for vehicle battery replacement. Candidate batteries with sufficient power are selected for battery replacement in the vehicle to avoid the battery to be replaced being too low, affecting the normal driving of the vehicle; for batteries with low power, the remaining power can be concentrated in some candidate batteries to avoid the batteries being idle or wasted due to insufficient power, thereby achieving reasonable redistribution of power.

[0016] In combination with the first aspect and the above implementation, in some possible implementations, the battery compartment of the battery swap station further includes a battery mutual charging compartment, and charging the third candidate battery based on the second candidate battery among the candidate batteries includes:

[0017] Move the second candidate battery and the third candidate battery to the battery mutual charging position;

[0018] Based on the battery mutual charging position, the second candidate battery is boosted;

[0019] The third candidate battery is charged based on the voltage-boosted second candidate battery.

[0020] In the above technical solution, a battery mutual charging position is configured in the battery swap station, and the second candidate battery and the third candidate battery with a charge less than a first charge threshold are moved to the battery mutual charging position, so that the battery mutual charging position can boost the voltage of the second candidate battery with lower charge; thereby, the second candidate battery can be used to charge the third candidate battery; there is no need to additionally configure a backup power supply for power supply abnormalities, and centralized transfer of power can be achieved by simply transferring the candidate batteries to the battery mutual charging position, ensuring that there are candidate batteries with higher charge to provide battery swap services for vehicle users, thereby reducing the operating costs of the battery swap station, extending the normal operating time of the battery swap station under power supply abnormalities, and providing vehicle users with better battery swap services.

[0021] In combination with the first aspect and the above implementation manner, in some possible implementation manners, the method further includes:

[0022] When the power of each candidate battery is less than the second power threshold, determining whether the power of the backup battery in the backup battery compartment meets the power consumption of the target component within the first preset time period;

[0023] If the power of the backup battery meets the power consumption of the target component within the first preset time period, the backup battery in the backup battery compartment will be used to power the candidate battery in the battery swap station.

[0024] In the above technical solution, when it is detected that the power of each candidate battery in the battery swap station is less than the second power threshold, it indicates that the overall power of the candidate batteries is low. At this time, it is determined whether the power of the spare battery in the spare battery compartment can meet the power consumption of the target component within the preset time. If it does, the spare battery can be used to power the target component and the candidate battery in the battery swap station at the same time. On the basis of ensuring that the spare battery can maintain the normal operation of the basic equipment in the battery swap station, the candidate battery with low power is charged, so that the battery swap station can better provide battery swap services for vehicle users and extend the service time of the battery swap station under abnormal power supply conditions.

[0025] In combination with the first aspect and the above implementation manner, in some possible implementation manners, the method further includes:

[0026] If the power of the backup battery does not meet the power consumption of the target component within the first preset time period, a target prompt message is output; wherein the target prompt message is used to indicate that the battery swap station cannot provide battery swap service.

[0027] In the above technical solution, when it is detected that the power of the backup battery cannot meet the power consumption of the target component within the first preset time period, a prompt message can be output to indicate that the current battery swap station cannot provide battery swap services, thereby preventing vehicle users from performing unnecessary battery swap operations due to ignorance of the power supply abnormality of the battery swap station, thereby improving the vehicle user experience; it also prevents the battery swap station from processing invalid service requests, thereby improving the operating efficiency of the battery swap station.

[0028] In combination with the first aspect and the above implementation manner, in some possible implementation manners, the method further includes:

[0029] When the power supply of the battery swap station is normal, obtaining the power consumption of the target component within a second preset time period;

[0030] Determining a third power threshold based on the power consumption of the target component within a second preset time period;

[0031] The backup battery in the backup battery compartment is charged so that the power level of the backup battery is greater than or equal to a third power threshold.

[0032] In the above technical scheme, when the power supply of the battery swap station is normal, the power consumption of the target component in the battery swap station within the second preset time period can be determined first; then the third power threshold can be determined according to the power consumption; and the backup battery in the backup battery compartment can be charged with the normal power supply, so that the power of the backup battery can reach the third power threshold for maintaining the operation of the target component; ensuring that when the power supply of the battery swap station is abnormal, the basic components of the battery swap station can be maintained to operate normally through the backup battery, avoiding the backup battery from being too low, resulting in service abnormalities when the power supply is abnormal (for example, the ongoing battery swap business cannot be terminated, etc.), or the battery swap service cannot be maintained for a certain period of time, which helps to improve user satisfaction with the battery swap station.

[0033] In combination with the first aspect and the above implementation manner, in some possible implementation manners, the method further includes:

[0034] Obtain target power supply parameters of the external power supply to the battery swap station;

[0035] When the target power supply parameter is less than the preset parameter threshold, it is determined that the power supply of the battery swap station is abnormal; or,

[0036] When the duration that the target power supply parameter is less than the preset parameter threshold reaches a third preset duration, it is determined that the battery swap station is in a power supply abnormality.

[0037] In the above technical scheme, by obtaining the target power supply parameters of the external power supply to the battery swap station and comparing them with the preset parameter threshold, the power supply status of the battery swap station can be judged quickly and accurately; when the target power supply parameter is less than the preset parameter threshold, or the duration of being less than the preset parameter threshold reaches a third preset time, it can be determined that the battery swap station is in an abnormal power supply state; so that the battery swap station can detect power supply problems in time, improve the accuracy of determining the working status of the battery swap station, and further improve the timeliness of emergency processing after detecting power supply abnormality of the battery swap station.

[0038] In combination with the first aspect and the above implementation manner, in some possible implementation manners, the method further includes:

[0039] When the battery swap station is in normal operation, the spare battery slot is the target battery slot.

[0040] In the above technical solution, when the battery swap station is operating normally, the spare battery slot is set as the target battery slot, that is, the spare battery in the spare battery slot can be directly called to provide battery swap services for vehicle users; and when the battery in the battery slot normally used for battery swap is used or is low on power, the battery can be obtained from the spare battery slot to ensure that the battery swap station always has enough available batteries to meet the battery swap needs of vehicle users, maintain the normal operation of the battery swap station, and avoid service interruptions due to insufficient battery supply. In addition, there is no need to set up a separate spare battery or backup power supply, which can reduce the operating cost of the battery swap station.

[0041] In a second aspect, a control device for a battery swap station is provided, the control device comprising:

[0042] A control module, used to control the relay of the spare battery position in the battery swap station to close when it is detected that the battery swap station is in a power supply abnormality; wherein the battery position of the battery swap station includes a target battery position and a spare battery position;

[0043] A power supply module, used to supply power to a target component in the battery swap station based on the backup battery in the backup battery compartment, so that the battery swap station can provide battery swap services; wherein the target component is used to control the normal operation of the battery swap station;

[0044] The battery replacement module is used to respond to the vehicle's battery replacement instruction and provide battery replacement services to the vehicle based on the target component and the target battery in the target battery compartment.

[0045] In conjunction with the second aspect, in some possible implementations, the control device is further used to obtain the power of each candidate battery in the target battery compartment;

[0046] Determine a first candidate battery whose power level among the candidate batteries is greater than or equal to a first power level threshold as a target battery in the target battery compartment;

[0047] Based on the second candidate battery among the candidate batteries, the third candidate battery is charged so that the power of the third candidate battery is greater than or equal to the first power threshold; wherein the power of the second candidate battery and the third candidate battery is less than the first power threshold, and the power of the second candidate battery is less than the power of the third candidate battery.

[0048] In combination with the second aspect and the above implementation, in some possible implementations, the battery storage space of the battery swap station further includes a battery mutual charging storage space, and the control device is further used to move the second candidate battery and the third candidate battery to the battery mutual charging storage space;

[0049] Based on the battery mutual charging position, the second candidate battery is boosted;

[0050] The third candidate battery is charged based on the voltage-boosted second candidate battery.

[0051] In combination with the second aspect and the above implementation, in some possible implementations, the control device is further used to determine whether the power of the backup battery in the backup battery bin meets the power consumption of the target component within the first preset time period when the power of each candidate battery is less than the second power threshold;

[0052] If the power of the backup battery meets the power consumption of the target component within the first preset time period, the backup battery in the backup battery compartment will be used to power the candidate battery in the battery swap station.

[0053] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the control device is also used to output target prompt information if the power of the backup battery does not meet the power consumption of the target component within a first preset time period; wherein the target prompt information is used to indicate that the battery swap station cannot provide battery swap service.

[0054] In combination with the second aspect and the above implementation, in some possible implementations, the control device is further used to obtain the power consumption of the target component within a second preset time period when the power supply of the battery swap station is normal;

[0055] Determining a third power threshold based on the power consumption of the target component within a second preset time period;

[0056] The backup battery in the backup battery compartment is charged so that the power level of the backup battery is greater than or equal to a third power threshold.

[0057] In combination with the second aspect and the above implementation, in some possible implementations, the control device is further used to obtain a target power supply parameter of the external power supply to the battery swap station;

[0058] When the target power supply parameter is less than the preset parameter threshold, it is determined that the power supply of the battery swap station is abnormal; or,

[0059] When the duration that the target power supply parameter is less than the preset parameter threshold reaches a third preset duration, it is determined that the battery swap station is in a power supply abnormality.

[0060] In combination with the second aspect and the above-mentioned implementations, in some possible implementations, the control device is also used to set the spare battery slot as the target battery slot when the battery swap station is in normal operation.

[0061] In a third aspect, a battery swap station is provided, the battery swap station comprising: a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, so that the vehicle executes the method in the first aspect or any possible implementation of the first aspect.

[0069] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0070] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0071] A battery swap station is a facility that provides power battery replacement services for electric vehicles. Its main functions include centralized storage, charging and rapid replacement of batteries. A battery swap station is usually equipped with multiple battery compartments for power batteries and has equipment and operating space for battery replacement. At the battery swap station, the power battery of an electric vehicle can be removed from the vehicle and replaced to meet the vehicle's driving needs.

[0072] The overall power supply source of the battery swap station is an external power source, such as the municipal power grid; when the external power source is cut off, the batteries in the battery swap station cannot be charged, the station control system cannot work, and the transfer mechanism cannot operate, which means that the battery swap station cannot provide normal battery swap services.

[0073] In view of the problems existing in the above prior art, the embodiments of the present application provide a control method, a control device and a battery swap station; when the control method of the battery swap station detects that the battery swap station is in an abnormal power supply state, the relay of the spare battery compartment in the battery swap station is controlled to close, so that the spare battery in the spare battery compartment can be used to power the target component in the battery swap station used to control the normal operation of the battery swap station, so as to maintain the basic work of the battery swap station; after receiving the battery swap command of the vehicle, in response to the battery swap command, the battery swap service can be provided to the vehicle through the target component and the battery in the target battery compartment. This method can maintain the battery swap service of the battery swap station for a certain period of time when the power supply of the battery swap station is abnormal, until the power supply is restored or the battery is exhausted.

[0074] Combine the following Figures 1 to 3 The control method of the battery swap station provided in the embodiment of the present application is described in detail.

[0075] Figure 1 Schematic diagram of a configuration of a battery swap station provided in an embodiment of the present application. Figure 1As shown, the battery swap station 100 is equipped with components such as a target component 101, a spare battery compartment 102, a target battery compartment 103 and a battery charging compartment 104.

[0076] The target component 101 is used to control the normal operation of the battery swap station, which may include the battery swap station controller (or station control system), camera, programmable logic controller (PLC), transfer mechanism, communication equipment and lighting equipment in the battery swap station. Among them, the battery swap station controller (or station control system) undertakes the important task of monitoring, managing and coordinating various equipment and business processes in the battery swap station to ensure the efficient, stable and safe operation of the battery swap station; its functions may include equipment monitoring, such as real-time collection and analysis of equipment data; battery swap process control, such as battery swap task scheduling, optimization process and management; battery management, such as battery status assessment and battery balancing and maintenance; energy management, such as power monitoring and optimization and energy access management. The camera can be used to detect the real-time situation in the battery swap station, such as personnel activities and the operation of the equipment in the station. The functions of the PLC include battery management, such as battery charging and discharging control, battery status detection, etc.; battery swap equipment control, such as controlling the mechanical arm and battery compartment door, etc.; safety protection, such as overcurrent protection, overheating protection and leakage protection. The transfer mechanism may include a robotic arm, a lifting motor, and a moving motor, etc., which are used to control the movement of batteries in various battery compartments, as well as control the removal of batteries from the vehicle and the loading of new batteries into the vehicle.

[0077] The backup battery compartment 102 can be used to place a backup battery. When the power supply of the battery swap station 100 is abnormal, the backup battery can be used to power the battery swap station 100.

[0078] The target battery compartment 103 can be used to place target batteries and candidate batteries, wherein the target battery is used to indicate a candidate battery whose battery power is greater than or equal to a preset threshold. When the vehicle user has a battery replacement demand, the target battery can be used to replace the battery for the vehicle.

[0079] The battery mutual charging position 104 may be a double position for placing at least two candidate batteries to be mutually charged, and the electricity in one candidate battery may be charged into another candidate battery.

[0080] Figure 2 This is a schematic flow chart of a control method for a battery swap station provided in an embodiment of the present application. It should be understood that the method can be applied to a battery swap station; or, to a station control system of a battery swap station; or, to a battery swap station controller of a battery swap station; or, to a chip configured in a battery swap station controller of a battery swap station.

[0081] For example, Figure 2As shown, the method 200 includes:

[0082] S201, when it is detected that the battery swap station is in a power supply abnormality, control the relay of the spare battery slot in the battery swap station to close; wherein the battery slot of the battery swap station includes a target battery slot and a spare battery slot.

[0083] Among them, the battery placed in the target battery compartment can be used as the battery to be replaced during the vehicle battery replacement process.

[0084] The battery swap station is equipped with multiple battery slots, which may include target battery slots and spare battery slots. The batteries in the target battery slots are used to provide battery swap services for vehicles. When a vehicle needs to swap batteries, the batteries in the target battery slots can be used to replace the batteries in the vehicle to achieve battery swap. The batteries in the spare battery slots can be used to power the swap station when the power supply of the swap station is abnormal. Each battery slot can be equipped with a relay, and when there is a need to use the battery in the current battery slot, it can be controlled by closing the relay.

[0085] For example, when it is detected that the battery swap station is in a power supply abnormality, the relay of the spare battery compartment can be controlled to close so that the battery in the spare battery compartment can be used as a power source to power the external circuit.

[0086] For example, under normal circumstances, the battery swap station is powered by an external power source such as the municipal grid to maintain the normal operation of the battery swap station; when the external municipal grid is powered off or there is a fault in the line connecting the battery swap station to the external municipal grid, the battery swap station cannot receive normal power supply, and it can be determined that the battery swap station is in a power supply abnormality.

[0087] It should be understood that when a vehicle goes to a battery swap station for battery swap, the old battery in the vehicle needs to be removed and the new battery in the battery swap station needs to be loaded into the battery compartment of the vehicle to achieve battery swap; therefore, under normal circumstances, there are batteries placed in the battery compartments of the battery swap station.

[0088] It should be noted that the battery involved in the embodiments of the present application may be a single battery or a battery pack, etc. The specific type can be determined according to the actual battery configuration in the battery swap station, and the embodiments of the present application do not limit this.

[0089] In one implementation, when the power supply of the battery swap station is normal, the power consumption of the target component within a second preset time period is obtained;

[0090] Determining a third power threshold based on the power consumption of the target component within a second preset time period;

[0091] The backup battery in the backup battery compartment is charged so that the power level of the backup battery is greater than or equal to a third power threshold.

[0092] Exemplarily, when the battery swap station is in normal working state, that is, the external power supply is normal, each battery in the battery swap station can be charged by the external power supply; at this time, the power consumption of the target component can be counted, for example, the power consumption of the target component within 3 days can be determined; after determining the power consumption, the corresponding third power threshold can be determined according to the power consumption; and then the spare battery in the spare battery compartment can be charged according to the third power threshold, so that the power of the spare battery can reach the third power threshold.

[0093] Optionally, since different types of batteries have different capacities, in order to ensure that the backup battery can provide energy supply to the battery swap station for a longer period of time, the backup battery can be charged to a full charge when the power supply is normal.

[0094] It should be understood that, since the battery capacity is limited to a certain extent, when the third power threshold determined according to the power consumption is greater than the capacity of the backup battery, the backup battery can be charged to a fully charged state.

[0095] In one implementation, a plurality of backup battery compartments may be configured, including a plurality of backup batteries. When the power of one of the backup batteries is exhausted, the power supply may be switched to another backup battery.

[0096] Optionally, a corresponding relationship can be pre-set between the power consumption and the third power threshold; in one implementation, the power consumption can be directly used as the third power threshold to charge the backup battery; in another implementation, the third power threshold can be determined as a power value greater than the power consumption to achieve redundant charging.

[0097] Optionally, in an embodiment of the present application, the description method of the battery power may include: battery state of charge (SOC) or battery state of energy (SOE). SOC, also known as the remaining power, is used to reflect the ratio of the current remaining power of the battery under certain conditions to the full power of the battery, usually expressed as a percentage. For example, an SOC of 50% means that the remaining power of the battery is half of the total capacity of the battery. SOE is used to indicate the ratio of the energy currently stored in the battery to the maximum energy that can be stored in the battery, and is also usually presented as a percentage.

[0098] In an embodiment of the present application, when the power supply of the battery swap station is normal, the power consumption of the target component in the battery swap station within the second preset time period can be first determined; then the third power threshold can be determined based on the power consumption; and the backup battery in the backup battery compartment can be charged using the normal power supply, so that the power of the backup battery can reach the third power threshold for maintaining the operation of the target component; ensuring that when the power supply of the battery swap station is abnormal, the basic components of the battery swap station can be maintained to operate normally through the backup battery, avoiding the backup battery being too low, resulting in service abnormalities when the power supply is abnormal (for example, the ongoing battery swap business cannot be terminated, etc.), or the battery swap service cannot be maintained for a certain period of time, which helps to improve user satisfaction with the battery swap station.

[0099] In one implementation, a target power supply parameter of an external power source to a battery swap station is obtained;

[0100] When the target power supply parameter is less than the preset parameter threshold, it is determined that the power supply of the battery swap station is abnormal; or,

[0101] When the duration that the target power supply parameter is less than the preset parameter threshold reaches a third preset duration, it is determined that the battery swap station is in a power supply abnormality.

[0102] Among them, the external power supply is used to indicate the power supply that supplies power to the battery swap station under normal circumstances; the target power supply parameters may include current parameters, voltage parameters, power parameters, etc.

[0103] Exemplarily, the station control system can monitor various data of the battery swap station, which may include the target power supply parameters of the external power supply to the battery swap station; pre-set parameter thresholds, such as current thresholds, voltage thresholds, and power thresholds, etc. When it is detected that the target power supply parameter is less than the preset parameter threshold, it indicates that there is an abnormality in the power supply process of the external power supply to the battery swap station, and it can be determined that the battery swap station is in a power supply abnormality.

[0104] Furthermore, in order to avoid a short-term decrease in power supply parameters, which may lead to an incorrect judgment of the power supply status of the battery swap station, a third preset time duration (for example, 10s) may be set; when it is detected that the target power supply parameter is less than the preset parameter threshold and the duration reaches the third preset time duration, it is determined that the battery swap station is in a power supply abnormality.

[0105] In an embodiment of the present application, by obtaining the target power supply parameters of the external power supply to the battery swap station and comparing them with the preset parameter threshold, the power supply status of the battery swap station can be quickly and accurately determined; when the target power supply parameter is less than the preset parameter threshold, or the duration of being less than the preset parameter threshold reaches a third preset duration, it can be determined that the battery swap station is in an abnormal power supply state; this enables the battery swap station to promptly detect power supply problems, improves the accuracy of determining the working status of the battery swap station, and further improves the timeliness of emergency processing after detecting power supply abnormality at the battery swap station.

[0106] In one implementation, when the battery swap station is in normal operation, the spare battery slot is the target battery slot.

[0107] For example, during the configuration of the battery swap station slots, there is no need to separately configure a backup power supply or backup battery, etc., to power the battery swap station in the event of abnormal power supply. When the battery swap station is in normal operation, the backup battery slot can also be used as a target battery slot for normal use, that is, the backup battery in the backup battery slot can also be used as a battery for replacing a low-power battery in the vehicle during the vehicle battery swap process. When the power supply of the battery swap station is abnormal, the backup battery in the backup battery slot can be controlled by controlling the relay of the backup battery slot to determine that the backup battery in the backup battery slot is used to power the target component.

[0108] Optionally, in one implementation, when the battery swap station is in normal operation, the battery charging position may also be the target battery position.

[0109] For example, when the power supply of the battery swap station is normal, batteries for vehicle battery swapping may also be placed in the battery inter-charging slots. At this time, the batteries in the battery inter-charging slots will not be charged inter-ally. When the power supply of the battery swap station is abnormal, the relay of the battery inter-charging slot is closed to control the batteries placed in the current slot to perform inter-charging operations.

[0110] In the embodiment of the present application, when the battery swap station is operating normally, the spare battery slot is set as the target battery slot, that is, the spare battery in the spare battery slot can be directly called to provide battery swap services for vehicle users; and when the battery in the battery slot normally used for battery swap is used or is low on power, etc., the battery can be obtained from the spare battery slot to ensure that the battery swap station always has enough available batteries to meet the battery swap needs of vehicle users, maintain the normal operation of the battery swap station, and avoid service interruptions due to insufficient battery supply. In addition, there is no need to set up a separate spare battery or backup power supply, which can reduce the operating cost of the battery swap station.

[0111] S202, based on the backup battery in the backup battery compartment, supply power to the target component in the battery swap station so that the battery swap station can provide battery swap services; wherein the target component is used to control the normal operation of the battery swap station.

[0112] Exemplarily, after the relay of the spare battery compartment is closed, the spare battery in the spare battery compartment can be used to power the station control system, camera, transfer mechanism and other target components in the battery swap station to ensure that the battery swap service currently being carried out in the battery swap station can operate normally; and the battery swap station can also maintain the battery swap service for a certain period of time in the event of power supply abnormality.

[0113] For example, when the power supply of the battery swap station is abnormal, the target components in the battery swap station cannot receive normal current, resulting in the target components being unable to work normally and providing battery swap services. After the target components are powered by backup batteries, each target component can receive normal current, so that the station control system can regulate the batteries and other components in the battery swap station, the camera can monitor the station environment, and the transfer mechanism can normally complete the battery swap operation for the vehicle.

[0114] S203, in response to the battery replacement instruction of the vehicle, providing battery replacement service to the vehicle based on the target component and the target battery in the target battery compartment.

[0115] For example, the battery swap station can provide battery swap services when the target component is powered by a backup battery. When the vehicle user has a battery swap demand, the battery swap service can be triggered; the station control system responds to the vehicle's battery swap instruction and can provide the vehicle with a battery swap service using the target component and the target battery in the target battery compartment.

[0116] Specifically, after the vehicle enters the battery swap station, the exhausted battery on the vehicle can be removed through the transfer mechanism and placed in a preset position; then the target battery with sufficient power is grabbed from the target battery compartment and loaded into the vehicle so that the vehicle can drive normally. During this process, the connectivity and safety of the vehicle and battery can also be checked to ensure that the battery is installed correctly.

[0117] In one implementation, the power of each candidate battery in the target battery compartment is obtained;

[0118] Determine a first candidate battery whose power level among the candidate batteries is greater than or equal to a first power level threshold as a target battery in the target battery compartment;

[0119] Based on the second candidate battery among the candidate batteries, the third candidate battery is charged so that the power of the third candidate battery is greater than or equal to the first power threshold; wherein the power of the second candidate battery and the third candidate battery is less than the first power threshold, and the power of the second candidate battery is less than the power of the third candidate battery.

[0120] Exemplarily, the power level of each candidate battery in the target battery compartment is monitored; a first power level threshold is set, such as 90%; if the power level of the first candidate battery is greater than or equal to the first power level threshold, the first candidate battery can be determined as the target battery for the battery swap station to swap the battery for the vehicle. For candidate batteries with a power level less than the first power level threshold, a second candidate battery with a lower power level and a third candidate battery with a higher power level can be determined; the second candidate battery is used to charge the third candidate battery, so that the power level of the third candidate battery is greater than or equal to the first power level threshold, and the third candidate battery can be used as the target battery to provide battery swap services for the vehicle.

[0121] It should be understood that the second candidate battery and the third candidate battery can be used to indicate two types of candidate batteries. During the process of mutual charging of the candidate batteries, the power of multiple low-power batteries can be concentrated in one candidate battery to obtain more target batteries that can provide sufficient power for vehicle users.

[0122] Exemplarily, the candidate batteries in the target battery compartment include candidate battery 1, whose charge is 100%; candidate battery 2, whose charge is 80%; candidate battery 3, whose charge is 10%; and candidate battery 4, whose charge is 5%. Taking the first charge threshold of 90% as an example, candidate battery 1 can be directly determined as the target battery, and in response to the vehicle battery replacement instruction, candidate battery 1 can be directly used for battery replacement operation; for the three candidate batteries whose charge is less than the first charge threshold, the charge of candidate battery 3 can be charged into candidate battery 2, so that the charge of candidate battery 2 reaches 90%, which is equal to the first charge threshold; or, the charge of candidate battery 3 and candidate battery 4 can be charged into candidate battery 2, so that the charge of candidate battery 2 reaches 95%, which is greater than the first charge threshold.

[0123] In the embodiment of the present application, the power of each candidate battery in the target battery compartment is obtained, and the first candidate battery with a power greater than or equal to the first power threshold is determined as an available battery; for the battery with a power less than the first power threshold, the second candidate battery with a lower power is used to charge the third candidate battery with a higher power, so that the power of the third candidate battery reaches the first power threshold, and the third candidate battery can be used for vehicle battery replacement. Candidate batteries with sufficient power are selected for battery replacement by the vehicle to avoid the battery to be replaced being too low, affecting the normal driving of the vehicle; for batteries with low power, the remaining power can be concentrated in some candidate batteries to avoid the battery being idle or wasted due to insufficient power, thereby achieving reasonable redistribution of power.

[0124] In one implementation, the battery compartment of the battery swap station further includes a battery mutual charging compartment, and based on the second candidate battery among the candidate batteries, the process of charging the third candidate battery may specifically include:

[0125] Move the second candidate battery and the third candidate battery to the battery mutual charging position;

[0126] Based on the battery mutual charging position, the second candidate battery is boosted;

[0127] The third candidate battery is charged based on the voltage-boosted second candidate battery.

[0128] Exemplarily, a battery mutual charging position may also be configured in the battery exchange position of the battery exchange station; when there is a need for mutual charging of batteries, a transfer mechanism may be used to move the second candidate battery and the third candidate battery from the target battery position to the battery mutual charging position, and the battery mutual charging position may include at least two positions, one of which may be used for battery discharging and the other for battery charging; thereafter, in order to form current between the batteries and complete the mutual charging operation, the discharge position in the battery mutual charging position may be used to boost the second candidate battery with lower power; and the boosted second candidate battery may be used to charge the third candidate battery.

[0129] In one implementation, when the power levels of candidate batteries in the battery swap station are all less than a first power threshold and are substantially consistent, any two or more candidate batteries may be charged mutually so that the battery power can be concentrated in some of the candidate batteries.

[0130] In an embodiment of the present application, a battery mutual charging position is configured in the battery swap station, and the second candidate battery and the third candidate battery with a charge less than a first charge threshold are moved to the battery mutual charging position, so that the battery mutual charging position can boost the voltage of the second candidate battery with lower charge; thereby, the second candidate battery can be used to charge the third candidate battery; there is no need to additionally configure a backup power supply for power supply abnormalities, and centralized transfer of power can be achieved only by transferring the candidate batteries to the battery mutual charging position, thereby ensuring that there are candidate batteries with higher charge to provide battery swap services for vehicle users, thereby reducing the operating costs of the battery swap station, extending the normal operating time of the battery swap station under power supply abnormalities, and providing vehicle users with better battery swap services.

[0131] In one implementation, when the power of each candidate battery is less than the second power threshold, it is determined whether the power of the backup battery in the backup battery compartment meets the power consumption of the target component within the first preset time period;

[0132] If the power of the backup battery meets the power consumption of the target component within the first preset time period, the backup battery in the backup battery compartment will be used to power the candidate battery in the battery swap station.

[0133] Exemplarily, a second power threshold (for example, 10%) is set that is less than the first power threshold; when it is detected that the power levels of the candidate batteries in the battery swap station are all less than the second power threshold, all the remaining power is concentrated in one candidate battery, and it may not be possible to make the power level of the candidate battery reach the first power threshold; at this time, it can be determined whether the current power level of the spare battery in the spare battery compartment can meet the power consumption of the target component within a first preset time period (for example, 1 day) so that the target component can operate normally in a short time; if it is determined that the power level of the spare battery can meet the power consumption of the target component within the first preset time period, the spare battery can be used to charge the candidate batteries in the battery swap station, so that after the power levels of the candidate batteries are concentrated, the power level of at least one candidate battery can reach the first power threshold (for example, 90%) through the charging operation of the spare battery.

[0134] Optionally, the first preset duration may be determined based on a predicted power outage duration of the external power source or a usage period of the battery swap station, which is not limited in this embodiment of the present application.

[0135] In the embodiment of the present application, when it is detected that the power of each candidate battery in the battery swap station is less than the second power threshold, it indicates that the overall power of the candidate batteries is low. At this time, it is determined whether the power of the backup battery in the backup battery compartment can meet the power consumption of the target component within the preset time; if it does, the backup battery can be used to power the target component and the candidate battery in the battery swap station at the same time. On the basis of ensuring that the backup battery can maintain the normal operation of the basic equipment in the battery swap station, the candidate battery with low power is charged, so that the battery swap station can better provide battery swap services for vehicle users and extend the service time of the battery swap station under abnormal power supply conditions.

[0136] In one implementation, if the power of the backup battery does not meet the power consumption of the target component within the first preset time period, a target prompt message is output; wherein the target prompt message is used to indicate that the battery swap station cannot provide battery swap service.

[0137] Exemplarily, when the current power of the backup battery cannot meet the power consumption of the target component within the first preset time period, the backup battery will not be used to charge the candidate battery, that is, the backup battery is only used to power the target component; then the target prompt information can be output to prompt the vehicle user or the staff of the battery swap station that the battery swap station is currently unable to provide battery swap services.

[0138] In an embodiment of the present application, when it is detected that the power of the backup battery cannot meet the power consumption of the target component within the first preset time period, a prompt message can be output to indicate that the current battery swap station cannot provide battery swap services, thereby preventing vehicle users from performing unnecessary battery swap operations due to ignorance of the power supply abnormality of the battery swap station, thereby improving the user experience of vehicle users; it also prevents the battery swap station from processing invalid service requests, thereby improving the operating efficiency of the battery swap station.

[0139] In summary, in the embodiments of the present application, when an abnormal power supply at the battery swap station is detected, the backup battery is used to supply power to the target component by closing the relay of the backup battery compartment, thereby ensuring that the key components in the battery swap station responsible for controlling its normal operation can continue to work, so that the battery swap station can provide normal battery swap services for the vehicle; when receiving the battery swap command of the vehicle, the battery swap service is provided to the vehicle through the target component and the target battery compartment in response to the battery swap command; the overall paralysis of the battery swap station due to the abnormal main power supply can be avoided, and the basic functions of the battery swap station can be maintained; it is ensured that normal battery swap services can still be provided in the case of abnormal power supply at the battery swap station, so that the vehicle undergoing battery swap will not be terminated due to a sudden power outage at the battery swap station, and the vehicle that has not started battery swap will not be unable to perform battery swap due to abnormal power supply at the battery swap station. In addition, this solution does not require the provision of an additional backup power supply, and the original batteries in the battery swap station can be used to achieve normal power supply when the power supply at the battery swap station is abnormal, which can reduce the configuration cost of the battery swap station.

[0140] Figure 3 This is a schematic flow chart of another control method for a battery swap station provided in an embodiment of the present application. It should be understood that the method can be applied to a battery swap station; or, to a station control system of a battery swap station; or, to a battery swap station controller of a battery swap station; or, to a chip configured in a battery swap station controller of a battery swap station.

[0141] For example, Figure 3 As shown, the method 300 includes:

[0142] S301, when abnormal power supply of the battery swap station is detected, output an alarm message.

[0143] In the embodiment of the present application, the battery slots in the battery swap station may include a spare battery slot, a battery mutual charging slot, and a target battery slot. When the battery swap station is operating normally, the spare battery slot and the battery mutual charging slot are the same as the target battery slot, but they also have the spare power supply function and the battery mutual charging function, which can be preset in the circuit and controlled by the relay.

[0144] Exemplarily, the station control system monitors the power supply parameters (such as voltage, current, power and other parameters) input by the external power supply to the battery swap station, and when it detects that the power supply parameters are less than the preset parameter threshold, it determines that the power supply of the battery swap station is abnormal; at this time, an alarm message is output to indicate that the power supply of the battery swap station is abnormal.

[0145] S302: When the duration of outputting the alarm information reaches a first preset duration, the battery swap station is controlled to be in an emergency mode.

[0146] Exemplarily, when it is detected that the duration of outputting the alarm information reaches a first preset duration (eg, 10s), the working mode of the battery swap station is switched to the emergency mode.

[0147] Optionally, the alarm information can be sent to the manager of the battery swap station; the manager can remotely view the abnormal status of the battery swap station, and then manually choose to switch the battery swap station to emergency mode; or, after the power supply of the battery swap station is abnormal, maintenance personnel can go to the battery swap station to switch the working mode of the battery swap station to emergency mode.

[0148] Optionally, when the battery swap station is in emergency mode, the current status of the battery swap station can be sent to the battery swap station backend and the battery swap station application to indicate that the battery swap station is currently in emergency mode and the battery swap service function may be limited.

[0149] S303, in the emergency mode, controlling the relay of the backup battery compartment to close so that the backup battery in the backup battery compartment can supply power to the target component.

[0150] Among them, the target components include station control system, battery swap station controller, camera, PLC and transfer mechanism.

[0151] Exemplarily, when the battery swap station is in emergency mode, it indicates that the external power supply cannot normally supply power to the battery swap station; at this time, the relay of the spare battery compartment can be controlled to close, so that the spare battery in the spare battery compartment can supply power to the target component in the battery swap station, so that the target component can maintain the normal battery swap service of the battery swap station.

[0152] Optionally, a battery swap station may be configured with multiple backup battery slots and backup batteries. When the backup battery in one backup battery slot runs out of power, it can automatically switch to another backup battery slot for power supply; and replace the exhausted backup battery to prepare for the next power switch.

[0153] Optionally, the backup battery compartment may also be called a backup power supply compartment, etc.; the embodiments of the present application do not specifically limit the naming of the battery compartment.

[0154] Optionally, in emergency situations such as power maintenance or natural disasters, when the battery swap station is switched to emergency mode, the battery power in the station can also be used as a public emergency backup energy source to provide charging and lighting services to nearby groups through the 220V interface that powers the station.

[0155] Optionally, the implementation of S303 can refer to Figure 2 The relevant description of S202 in the present application embodiment will not be repeated here.

[0156] S304, boosting the low-power battery according to the power of the candidate batteries, and charging the high-power battery so that the power of the high-power battery is greater than or equal to a first power threshold.

[0157] Exemplarily, a battery swap station may be configured with multiple target battery slots, which can be used to store candidate batteries for vehicle battery swapping; the station control system monitors parameters such as the charge and position of each candidate battery. The charge of each candidate battery may be different, among which there are target batteries with a charge greater than or equal to a first charge threshold, and candidate batteries with a charge less than the first charge threshold. For candidate batteries with a charge less than the first charge threshold, high-charge batteries and low-charge batteries can be determined, and according to the principle of transferring the charge of low-charge batteries to high-charge batteries, the candidate batteries to be processed are moved to the battery mutual charging slot, and the low-charge batteries are boosted by using the battery mutual charging slot, so that the charge in the low-charge battery can be transferred to the high-charge battery, and the high-charge battery is charged until the charge of the high-charge battery is greater than or equal to the first charge threshold.

[0158] Optionally, the implementation of S304 can refer to Figure 2 The relevant description of S203 in the present application embodiment will not be repeated here.

[0159] S305, in response to the battery replacement instruction of the vehicle, using the target battery to provide a battery replacement service for the vehicle, wherein the target battery is used to indicate a battery with a power level greater than or equal to a first power threshold.

[0160] Exemplarily, when a vehicle user has a demand for battery replacement, a battery replacement instruction can be generated; after receiving the vehicle's battery replacement instruction, a target battery with a power level greater than or equal to a first power threshold can be used to provide the vehicle with a battery replacement service.

[0161] Optionally, the implementation of S305 can refer to Figure 2 The relevant description of S203 in the present application embodiment will not be repeated here.

[0162] S306: When the power levels of the candidate batteries are all less than the second power threshold, a target prompt message is output to indicate that the current battery replacement service is unavailable.

[0163] The second power threshold is smaller than the first power threshold.

[0164] Exemplarily, during the operation of the battery swap station, the power level of each candidate battery is detected in real time; when the power level of all candidate batteries is less than a second power threshold, it indicates that the total power that the battery swap station can provide may not be able to replace the battery of the vehicle, or cannot provide the vehicle with a battery with sufficient power, then a target prompt message can be output to indicate that the current battery swap service is unavailable.

[0165] S307, when it is detected that the time after the power supply of the battery swap station is restored to normal reaches a second preset time, control the battery swap station to switch to a normal working mode.

[0166] Exemplarily, after detecting that the power supply of the battery swap station has returned to normal, if the duration of normal power supply reaches a second preset duration (for example, 5s), the battery swap station is switched from the emergency mode to the normal working mode.

[0167] Optionally, when it is detected that the power supply of the battery swap station has returned to normal, the manager of the battery swap station can send a normal mode request to the battery swap station. Upon receiving the normal mode request, the battery swap station can be switched to the normal working mode; or when it is detected that the time for which the normal mode request has not been received reaches a preset threshold, the battery swap station will be automatically switched to the normal working mode.

[0168] In summary, in the embodiment of the present application, when an abnormal power supply of the battery swap station is detected and an alarm message is output, it switches to the emergency mode after reaching a first preset time, and by closing the backup battery position relay, the backup battery is used to power the target components, thereby ensuring that when the external power supply such as the mains power is abnormal, the basic components of the battery swap station can still operate normally and maintain the basic operation order within the station; according to the power level of the candidate batteries, the low-power battery is boosted and then charged to the high-power battery, so that the power level of the high-power battery reaches or exceeds the first power threshold, and the power is concentrated in some batteries, making full use of the battery resources in the station, thereby increasing the available capacity of the overall battery, reducing the idle waste of batteries that may be caused by power supply abnormalities, and also reserving batteries with sufficient power for subsequent vehicle battery swaps to ensure battery swap services. Continuity; when responding to a vehicle battery swap command, the target battery with a power level greater than or equal to the first power threshold is used to provide the vehicle with a battery swap service to ensure that the vehicle can obtain a battery with sufficient power; when the power levels of the candidate batteries are all less than the second power threshold, the target prompt information is output to inform users and managers that the current battery swap service is unavailable, which can avoid users' ineffective waiting. Managers can also take corresponding measures based on the prompt information to improve users' satisfaction and trust in the battery swap service; after detecting that the power supply of the battery swap station has returned to normal, the battery swap station is controlled to switch to normal working mode only after the second preset time has expired, ensuring that after the city power supply is stable, the battery swap station can safely and smoothly switch from emergency mode back to normal working mode, avoiding equipment failure or service interruption that may be caused by premature switching.

[0182] If the power of the backup battery meets the power consumption of the target component within the first preset time period, the backup battery in the backup battery compartment will be used to power the candidate battery in the battery swap station.

[0183] In one possible implementation, the control device 400 is also used to output a target prompt message if the power level of the backup battery does not meet the power consumption of the target component within a first preset time period; wherein the target prompt message is used to indicate that the battery swap station cannot provide battery swap service.

[0184] In a possible implementation, the control device 400 is further used to obtain the power consumption of the target component within a second preset time period when the power supply of the battery swap station is normal;

[0185] Determining a third power threshold based on the power consumption of the target component within a second preset time period;

[0186] The backup battery in the backup battery compartment is charged so that the power level of the backup battery is greater than or equal to a third power threshold.

[0187] In a possible implementation, the control device 400 is further used to obtain target power supply parameters of the external power supply to the battery swap station;

[0188] When the target power supply parameter is less than the preset parameter threshold, it is determined that the power supply of the battery swap station is abnormal; or,

[0189] When the duration that the target power supply parameter is less than the preset parameter threshold reaches a third preset duration, it is determined that the battery swap station is in a power supply abnormality.

[0190] In a possible implementation, the control device 400 is also used to set the spare battery slot as the target battery slot when the battery swap station is in normal operation.
