Description

Technical Field

[0001] This application relates to the field of electric vehicle battery swapping technology, and in particular to a method, control device, battery swapping cabinet, battery swapping system, and computer-readable storage medium for swapping batteries for light electric vehicles based on a two-wheeled vehicle battery swapping cabinet. Background Technology

[0002] To meet the demands of energy conservation and environmental protection, and with the development of electric vehicle technology, more and more light electric vehicles are being integrated into people's daily lives, such as unmanned logistics vehicles and AGV (Automated Guided Vehicle) cars.

[0003] Compared to electric vehicles (two-wheeled vehicles) that can be driven by a single battery, these light electric vehicles often require more power, which means they need to be equipped with larger capacity batteries. However, this means that large capacity batteries are not only more prone to fire and pose greater safety hazards, but also make it inconvenient for light electric vehicles to recharge, because large-capacity batteries are not easy to replace at any time. They can generally only be charged by direct plugging in a charging cable. However, this means that light electric vehicles cannot be used while charging, which affects their efficiency.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] The main purpose of this application is to provide a battery swapping method, control equipment, battery swapping cabinet, battery swapping system, and computer-readable storage medium for light electric vehicles based on a two-wheeled vehicle battery swapping cabinet. The aim is to facilitate the replenishment of power for light electric vehicles, avoid affecting the usage efficiency of light electric vehicles due to replenishment of power, and reduce the potential electrical hazards of light electric vehicles.

[0006] To achieve the above objectives, this application provides a battery swapping method for light electric vehicles based on a two-wheeled vehicle battery swapping cabinet, comprising the following steps:

[0007] When the battery swapping cabinet receives a battery swapping instruction from the cloud service platform for a light electric vehicle, it opens the doors of the two empty battery compartments. The light electric vehicle is powered by at least two batteries, and the battery swapping cabinet is a two-wheeled vehicle battery swapping cabinet.

[0008] After detecting that batteries have been inserted into the two empty battery compartments, the doors of the two battery compartments whose battery charge meets the preset conditions are opened;

[0009] The system checks whether the batteries in the two battery compartments are reinserted after they are removed and before the compartment doors are closed.

[0010] If so, return to the step of opening the doors of the two battery compartments whose battery charge levels meet the preset conditions;

[0011] If not, the battery swapping of the light electric vehicle is deemed complete.

[0012] To achieve the above objectives, this application also provides a control device, the control device comprising: a memory, a processor, and a battery swapping program for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet, stored in the memory and executable on the processor, wherein when the battery swapping program for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet is executed by the processor, the steps of the battery swapping method for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet described above are implemented.

[0013] To achieve the above objectives, this application also provides a battery swapping cabinet, which includes the control device described above.

[0014] To achieve the above objectives, this application also provides a battery swapping system, which includes a light electric vehicle and a battery swapping cabinet as described above.

[0015] Optionally, the light electric vehicle is provided with 6 storage compartments for placing batteries. Every two storage compartments are connected in series to form a group, and the storage compartments in each group are connected in parallel and supply power to the light electric vehicle in turn on a group basis.

[0016] To achieve the above objectives, this application also provides a computer-readable storage medium storing a battery swapping program for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet. When the battery swapping program for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet is executed by a processor, it implements the steps of the battery swapping method for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet as described above.

[0017] This application provides a method, control device, battery swapping cabinet, battery swapping system, and computer-readable storage medium for swapping batteries in light electric vehicles based on a two-wheeled vehicle battery swapping cabinet. By designing a system that allows light electric vehicles to be powered by at least two conventional batteries connected in series, it eliminates the need for a single large-capacity battery to power the vehicle. This not only avoids the risk of fire or other safety hazards caused by excessively large batteries, but also allows the use of a battery swapping cabinet designed for conventional electric vehicles. This facilitates convenient recharging of the light electric vehicle and increases swapping efficiency, reducing the impact of recharging on its operational efficiency. Furthermore, by adopting a system where two battery compartments are opened at a time and batteries are stored first and then retrieved, even if more than two batteries need to be replaced, the cabinet only needs to maintain two empty battery compartments. Compared to a system where only the number of battery compartments opened depends on the number of batteries to be replaced, this approach effectively prevents battery theft and improves the utilization rate of the battery compartments.

[0023] Reference Figure 1 In one embodiment, the battery swapping method for light electric vehicles based on a two-wheeled vehicle battery swapping cabinet includes:

[0024] Step S10: When the battery swapping cabinet receives the battery swapping instruction for the light electric vehicle sent by the cloud service platform, it opens the doors of the two empty battery compartments, wherein the light electric vehicle is powered by at least two batteries.

[0025] Step S20: After detecting that batteries have been inserted into the two empty battery compartments, open the compartment doors of the two battery compartments whose battery charge meets the preset conditions.

[0026] Step S30: Detect whether the batteries in the two battery compartments have been reinserted after being removed and before the compartment doors are closed;

[0027] Step S40: If yes, return to the step of opening the doors of the two battery compartments whose battery charge meets the preset conditions;

[0028] Step S50: If not, determine that the battery swapping of the light electric vehicle is complete.

[0029] In this embodiment, the execution terminal can be a battery swapping cabinet (such as a control device installed inside the battery swapping cabinet) or a control device that controls the battery swapping cabinet (such as a cloud server). The following description uses the example of an execution terminal installed in a battery swapping cabinet.

[0030] Optionally, a light electric vehicle can be pre-designed to be powered by multiple batteries. Preferably, the light electric vehicle can accommodate up to six batteries, and at least two of these batteries can be used simultaneously to power the light electric vehicle. Taking a light electric vehicle with six batteries as an example, the six batteries are paired up in twos. At any given time, two battery groups connected in series can be used to power the light electric vehicle. When the power of one battery group is depleted, another fully charged battery group is used to continue powering the light electric vehicle, and so on.

[0031] It should be noted that the batteries used in light electric vehicles can be of the same specifications as those used in conventional electric vehicles (such as 48V 25Ah or 60V 20Ah batteries). Simply connect these batteries in series to simultaneously power and drive the light electric vehicle.

[0032] Optionally, the battery swapping cabinet provided in this embodiment can be a battery swapping cabinet suitable for conventional two-wheeled electric vehicles (hereinafter referred to as two-wheeled vehicle battery swapping cabinet). This type of battery swapping cabinet is equipped with multiple battery compartments, which can hold batteries. Unlike existing battery swapping cabinets, the battery swapping cabinet provided in this embodiment retains at least two unused battery compartments.

[0033] Meanwhile, this embodiment also provides a cloud service platform for users of light electric vehicles (such as vehicle owners or managers). Users can access the cloud service platform using mobile terminals and issue battery swapping instructions for light electric vehicles. They can also use the cloud service platform to settle related fees, check orders, and make battery swapping appointments.

[0034] Users can access the cloud service platform by scanning the QR code displayed on the battery swapping station; or by using the corresponding application to access the cloud service platform.

[0035] Optionally, when a user of a light electric vehicle (such as a vehicle owner or manager) needs to replace the battery in the light electric vehicle, they can issue a battery swap instruction on the cloud service platform. When editing the battery swap instruction, they can select the number of batteries that need to be replaced in their light electric vehicle (at least two batteries each time).

[0036] Optionally, when the battery swapping station receives a battery swapping instruction from the cloud service platform for a light electric vehicle, it first opens the doors of the two available battery compartments. At this point, the user can remove two batteries (e.g., batteries with insufficient or low charge) from the light electric vehicle and insert them into the two opened battery compartments respectively. Generally, the battery swapping station will automatically close the compartment doors after a certain period of time after opening; alternatively, the doors can be manually closed by the user.

[0037] Optionally, if the battery swapping cabinet detects through its battery presence detection circuit that batteries are inserted into both closed battery compartments (i.e., the two previously open empty battery compartments), it determines the battery charge level in each compartment (i.e., the charge level of the batteries inserted in the compartments), selects two battery compartments whose battery charge levels meet preset conditions, and opens the doors of the selected two battery compartments. At this point, the user can remove two batteries from the two opened battery compartments and insert them into the light electric vehicle.

[0038] Optionally, the preset conditions include at least one of the following:

[0039] The battery inside the compartment is fully charged;

[0040] The battery charge levels in the two battery compartments that are opened simultaneously are both greater than or equal to the battery charge levels of the other batteries in the battery swapping cabinet.

[0041] The difference in battery charge between the batteries in the two battery compartments that are opened simultaneously is less than a preset difference.

[0042] If at least two battery compartments in the battery swapping cabinet have fully charged batteries, then the doors of those two battery compartments can be opened directly.

[0043] If there are fewer than two battery compartments with fully charged batteries, then the battery compartments with the highest and lowest battery levels (the higher the ranking, the higher the battery level) can be selected, and the doors of these two battery compartments can be opened.

[0044] Alternatively, if there are fewer than two battery compartments with fully charged batteries, the two compartments with a difference in battery charge between them that is less than a preset difference can be selected, and their doors opened. It should be noted that the preset difference is used to measure the stability when two batteries are supplying power simultaneously (the smaller the difference, the more stable). The specific value can be set according to actual needs, as long as it is a safe value suitable for battery use. This way, a stable pair of batteries can be provided to light electric vehicles simultaneously, ensuring the safety of battery-powered light electric vehicles. If there are multiple pairs of battery compartments with a difference in battery charge between them that is less than the preset difference, the pair with the largest total battery charge should be selected, and their doors opened.

[0045] Of course, in some cases, the battery swapping cabinet can make a comprehensive judgment based on factors such as the battery charge, battery health status (SOH), and battery voltage difference (which can be measured by the difference in charge between the batteries in the compartment), and pair the battery compartments in pairs to ensure the consistency of the swapped batteries.

[0046] Optionally, after the user removes two batteries and inserts them into the light electric vehicle, if there are no more batteries that need to be replaced, the user can directly close the doors of the two battery compartments where the batteries were just removed; if there are still batteries that need to be replaced, the user can continue to remove two batteries that need to be replaced from the light electric vehicle and insert them into the two battery compartments where the batteries were just removed, and then close the doors of the two battery compartments (or the battery swapping cabinet can open the doors of the two battery compartments and then automatically close the doors after a certain period of time).

[0047] Optionally, after the battery swapping cabinet completes step S20, from the time the batteries are removed from the two opened battery compartments until the compartment doors are closed again, it is checked whether batteries have been reinserted into the two battery compartments. It should be noted that each battery compartment can be equipped with a corresponding battery presence detection circuit, which allows the battery swapping cabinet to detect whether a battery is inserted into the corresponding battery compartment.

[0048] Optionally, if it is detected that batteries have been reinserted into either of the two battery compartments, indicating that the user still needs to swap batteries, the battery swapping cabinet can return to the step of opening the doors of the two battery compartments whose battery levels meet the preset conditions. This allows the cabinet to select two more battery compartments whose battery levels meet the preset conditions and open their doors, enabling the user to continue swapping batteries (i.e., removing batteries from the two newly opened battery compartments and inserting them into the light electric vehicle). In this way, the user can swap two batteries each time, continuing this process until all the batteries required by the user have been swapped.

[0049] Optionally, if it is detected that the batteries in the two open battery compartments have been removed and have not been reinserted before the compartment doors are closed, it indicates that the user no longer needs to swap batteries (i.e., the batteries have been swapped). In this case, the battery swapping cabinet can determine that the current light electric vehicle has been swapped, and there is no need to perform the step of opening the doors of the two battery compartments where the battery charge meets the preset conditions.

[0050] In one embodiment, a light electric vehicle is designed to be powered by at least two conventional batteries connected in series, eliminating the need for a single large-capacity battery to power the vehicle. This not only avoids the risk of fire or other safety hazards caused by excessively large batteries, but also allows the use of battery swapping cabinets designed for conventional electric vehicles. This not only facilitates recharging the light electric vehicle but also increases swapping efficiency, reducing the impact of recharging on its overall performance. Furthermore, by opening two battery compartments at a time and using a "store first, retrieve later" approach, even if more than two batteries need to be replaced, the swapping cabinet only needs two empty compartments. Compared to opening as many compartments as needed, this design effectively prevents battery theft and improves the utilization rate of the battery compartments.

[0051] Moreover, the implementation of this embodiment only requires the use of a battery swapping cabinet (i.e., a two-wheeled vehicle battery swapping cabinet) for swapping batteries for conventional two-wheeled vehicles (i.e., two-wheeled electric vehicles). In other words, the battery swapping cabinet used in this embodiment can provide battery swapping services for two-wheeled vehicles simultaneously. (It should be understood that the battery swapping cabinet can provide different battery swapping strategies for light electric vehicles and two-wheeled vehicles. For example, for light electric vehicles, the battery swapping scheme of steps S10-S50 is provided, while for two-wheeled vehicles, the scheme of swapping batteries for two-wheeled vehicles using a conventional battery swapping cabinet can be adopted.) Therefore, the implementation cost of this embodiment is low (only the corresponding control program of the existing two-wheeled vehicle battery swapping cabinet needs to be changed), and it can be compatible with battery swapping for both light electric vehicles and two-wheeled vehicles, resulting in great economic benefits.

[0052] In one embodiment, based on the above embodiment, after the step of detecting that two empty battery compartments have batteries inserted and opening the doors of the two battery compartments whose battery charge meets a preset condition, the method further includes:

[0053] When there are no batteries in the battery swapping cabinet that meet the preset conditions, if a battery is detected inserted in the battery compartment with the current door open, then closing the battery compartment door is prohibited.

[0054] In this embodiment, as long as the battery charge in at least two battery compartments in the battery swapping cabinet meets the preset conditions, the battery can be swapped for the light electric vehicle; otherwise, the battery swapping for the light electric vehicle must be refused.

[0055] Optionally, after the battery swapping cabinet completes step S20, if there are no batteries in the cabinet that meet the preset conditions (i.e., the number of battery compartments with batteries that meet the preset conditions is less than two), and if it is detected that batteries have been removed from the two opened battery compartments and then reinserted (for example, after a user removes a battery provided by the battery swapping cabinet and inserts it into a light electric vehicle, and then removes two batteries with insufficient charge from the light electric vehicle and inserts them into the two battery compartments respectively), then the battery swapping cabinet can prevent the battery compartments with reinserted batteries from closing their doors (at this time, the battery swapping cabinet will neither automatically close the doors nor allow the user to manually close them). In this way, the user can only take the batteries with insufficient charge back to the light electric vehicle first, and then come to the battery swapping cabinet to swap batteries when there are batteries that meet the preset conditions (when the battery swapping cabinet has batteries that meet the preset conditions, it can send a notification message to the user's associated mobile terminal through the cloud service platform to notify the user to drive the light electric vehicle to swap batteries).

[0056] In one embodiment, based on the above embodiment, after the step of opening the doors of the two battery compartments whose battery charge meets a preset condition after detecting that two empty battery compartments have been inserted with batteries, the method further includes:

[0057] If the number of batteries currently provided does not meet the required number corresponding to the battery swapping instruction, then when it is detected that a battery has been inserted into the battery compartment with the currently open door, the door of the battery compartment must not be closed.

[0058] In this embodiment, when a user of a light electric vehicle edits a battery swapping instruction on the cloud service platform, they can select the number of batteries that need to be replaced (i.e., the required number). The cloud service platform can display the number of batteries available at the battery swapping station (i.e., the number of batteries that meet preset conditions) for the user's reference. Furthermore, the number of batteries the user can select on the cloud service platform must not exceed the maximum number of batteries that the battery swapping station can provide.

[0059] Optionally, before the battery compartment door of the battery swapping cabinet is allowed to close, it will be checked in advance each time whether the number of batteries currently provided to the user has met the required number corresponding to the battery swapping instruction.

[0060] If it is detected that the number of batteries currently provided to the user does not meet the required number corresponding to the battery swapping instruction, then when it is detected that there are batteries inserted in the two battery compartments with the current door open, the door of the battery compartment is allowed to be closed, and the process returns to the step of opening the doors of the two battery compartments whose battery charge meets the preset conditions.

[0061] If it is detected that the number of batteries currently provided to the user has met the required number corresponding to the battery swapping instruction, and it is detected that after the batteries in the two opened battery compartments have been removed and then reinserted, the battery swapping cabinet will close the compartment door to prevent the reinserted batteries from being inserted.

[0062] In one embodiment, based on the above embodiments, the battery swapping method for light electric vehicles based on two-wheeled vehicle battery swapping cabinets further includes:

[0063] The cloud service platform calculates the billing based on the number of batteries swapped for the light electric vehicle and sends the billing results to the associated account of the light electric vehicle on the cloud service platform.

[0064] In this embodiment, after determining that the battery swapping of the light electric vehicle is completed, the battery swapping cabinet can feed back the number of batteries swapped by the light electric vehicle (i.e., the number of batteries swapped) to the cloud service platform.

[0065] Alternatively, when a user of a light electric vehicle edits a battery swap instruction on the cloud service platform, if they select the required number of batteries to be swapped, the cloud service platform will directly use the required number as the number of batteries to be swapped for the light electric vehicle.

[0066] Optionally, after obtaining the number of batteries to be swapped for the light electric vehicle, the cloud service platform can calculate the billing based on the number of batteries swapped and the corresponding swapping unit price, and send the billing result (including the specific battery swapping fee) to the associated account of the light electric vehicle on the cloud service platform. If the associated account has pre-deposited funds, the corresponding battery swapping fee will be deducted directly from the associated account, or the user can pay the battery swapping fee generated by the associated account online.

[0067] This makes it convenient for users to pay for battery swapping in light electric vehicles.

[0068] This application embodiment also provides a control device, the internal structure of which can be as follows: Figure 2 As shown, the control device includes a processor, memory, communication interface, and database connected via a system bus. The processor provides computing and control capabilities. The memory of the control device includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores the operating system, computer programs, and database. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The database of the control device stores the battery swapping program for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet. The communication interface of the control device is used for data communication with external terminals. The input device of the control device is used to receive signals input from external devices. When the computer program is executed by the processor, it implements a battery swapping method for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet as described in the above embodiment.

[0069] Those skilled in the art will understand that Figure 2 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the control device to which the present application is applied.

[0070] Furthermore, this application also proposes a battery swapping cabinet, which is equipped with the control device described in the above embodiments. Since this battery swapping cabinet adopts all the technical solutions of all the above embodiments, it possesses at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be elaborated upon here.

[0071] Furthermore, this application also proposes a battery swapping system, including a light electric vehicle and a battery swapping cabinet as described in the above embodiments. Since this battery swapping system adopts all the technical solutions of all the above embodiments, it possesses at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be elaborated upon here.

[0072] Optionally, the light electric vehicle has six battery compartments, with each pair of compartments connected in series as a group. These groups are connected in parallel and supply power to the light electric vehicle in turn, group by group. That is, when a pair of batteries in one group is depleted, another group with sufficiently charged batteries continues to power the light electric vehicle, thus ensuring the vehicle's range when powered by batteries. Furthermore, when swapping batteries using the battery swapping cabinet, the two batteries swapped each time are preferably from the same group of compartments.

[0073] For example, when the driving voltage of a light electric vehicle is 96V, a single battery can be a 48V 25Ah specification. In this way, the output voltage of the two batteries connected in series in a set of compartments in a light electric vehicle can reach 96V, which is sufficient to drive the light electric vehicle.

[0074] Furthermore, this application also proposes a computer-readable storage medium comprising a battery swapping program for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet. When executed by a processor, the battery swapping program for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet implements the steps of the battery swapping method for a light electric vehicle based on a two-wheeled vehicle battery swapping cabinet as described in the above embodiments. It is understood that the computer-readable storage medium in this embodiment can be a volatile readable storage medium or a non-volatile readable storage medium.

[0075] In summary, the battery swapping method, control device, battery swapping cabinet, battery swapping system, and computer-readable storage medium for light electric vehicles based on two-wheeled vehicle battery swapping cabinets provided in this application embodiment are designed to power light electric vehicles using at least two conventional batteries connected in series. This eliminates the need for a single large-capacity battery to power the light electric vehicle. This not only avoids the risk of fire or other safety hazards caused by excessively large batteries in light electric vehicles, but also allows the use of battery swapping cabinets designed for conventional electric vehicles, making it convenient to recharge light electric vehicles. Yes, and this method is highly efficient, reducing the impact of recharging light electric vehicles on their usage efficiency. Furthermore, when using the battery swapping cabinet to swap batteries for light electric vehicles, the cabinet only needs to maintain two empty battery compartments even if the number of batteries to be replaced exceeds two. Compared to the method of opening as many battery compartments as the number of batteries to be replaced, this method effectively prevents battery theft and improves the utilization rate of the battery swapping cabinet's battery compartments.

[0076] Those skilled in the art will understand that all or part of the processes in the methods of the above embodiments can be implemented by a computer program instructing related hardware. The computer program can be stored in a non-volatile computer-readable storage medium. When executed, the computer program can include the processes of the embodiments of the above methods.
