Description

Technical Field

[0001] The present invention relates to the technical application field of battery swapping, and particularly to a convenient battery swapping method and system for shared electric vehicles. Background Art

[0002] Currently, the energy replenishment methods for two-wheeled electric bicycles, electric motorcycles, three-wheeled electric vehicles, etc. on the market are mainly divided into two categories: charging and battery swapping. Among them, most of these vehicles in the commercial field choose the battery swapping method due to high usage frequency and tight time tasks, such as food delivery workers, couriers, etc.

[0003] Although battery swapping saves users' time compared to charging, during the battery swapping process, the complex and cumbersome operation process often causes some troubles to users and hinders the smooth use of users. For example, there is no signal communication between the battery and the battery swapping cabinet before the battery is put into the battery swapping cabinet. Only after the battery is put into the battery swapping cabinet and the cable is connected, can the battery swapping cabinet perform a safety verification on the state of the battery, and the next operation can be carried out after passing the safety verification; and to put the battery into the battery swapping cabinet, the user must scan the code to let the battery swapping cabinet receive the user's request instruction and verify and judge the user's identity. This series of operations requires the user to actively execute and patiently wait for the result feedback from the system.

[0004] In practical applications, users are often anxious about the above operations due to being in a hurry, increasing the risk of damage to the equipment during the operation process. Therefore, this technology provides a new and more convenient battery swapping operation method for users, thus greatly improving the user experience. Summary of the Invention

[0005] The present invention provides a convenient battery swapping method and system for shared electric vehicles to simplify the battery swapping process and speed up the battery swapping speed, thereby solving the technical problems mentioned in the background art.

[0006] One technical solution of the present invention is as follows: A convenient battery swapping method for shared electric vehicles includes: S10: When the discharge interface of the shared battery is disconnected from the electric vehicle, the shared battery management device determines whether to search for a battery swapping cabinet within a preset distance according to the current battery level of the shared battery; S20: When the current battery level of the shared battery is lower than a preset value, the shared battery management device establishes wireless communication with the control system of the nearest battery swapping cabinet within the preset distance and sends a battery swapping request; S30: According to the battery swapping request, the control system of the battery swapping cabinet verifies the real-time state of the shared battery and the user account. After passing the verification, it opens an empty battery compartment in the battery swapping cabinet; S40: After the control system of the battery swapping cabinet detects that the shared battery is placed in the empty battery compartment and the compartment door is closed, it opens another battery compartment in the battery swapping cabinet that contains a replacement shared battery.

[0007] Further, the battery swapping cabinets that can be searched in the step S10 need to meet the following conditions: there is at least one empty battery compartment and at least one battery compartment equipped with fully charged shared batteries in the battery swapping cabinet.

[0008] Further, the step S30 includes: The control system of the battery swapping cabinet determines the number and real-time status of the shared battery to be replaced according to the battery swapping request sent by the management device of the shared battery; According to the number of the shared battery, determine the user account number and basic battery parameters corresponding to the number of the shared battery; Perform a safety verification on the shared battery according to the basic battery parameters and real-time status of the shared battery; After the battery safety verification is completed, perform an identity verification and balance verification on the user account. After the verification is passed, open the empty battery compartment in the battery swapping cabinet.

[0009] Further, after the control system of the battery swapping cabinet detects that the replaced shared battery is taken out of the battery compartment, it corresponds the number of the replaced shared battery with the user account number, and cancels the corresponding relationship between the number of the replaced shared battery and the user account number.

[0010] Further, the performing a safety verification on the shared battery according to the basic battery parameters and real-time status of the shared battery includes: The basic battery parameters include: the model, production date, and available days of the shared battery; The real-time status of the shared battery includes: the current battery level, real-time battery voltage, and real-time battery temperature; Verify the available days, real-time battery voltage, and real-time battery temperature of the shared battery; When the available days are equal to 0, or the real-time battery voltage or real-time battery temperature is not within the safe range, the safety verification fails; The control system of the battery swapping cabinet stops charging the shared battery that fails the safety verification and notifies the management staff to replace the shared battery.

[0011] Further, the performing an identity verification and balance verification on the user account. After the verification is passed, opening the empty battery compartment in the battery swapping cabinet includes: Verify whether the user account is in a normal state and whether the monthly battery swapping function is enabled. When the user account is in a normal state and the monthly battery swapping function is enabled, open the empty battery compartment in the battery swapping cabinet; When the user account does not have the monthly battery replacement function enabled, verify whether the user account has the quick battery replacement function enabled. When the user account does not have the quick battery replacement function enabled, a battery replacement confirmation button is popped up on the screen of the battery replacement cabinet. After the user clicks the confirmation button, the account balance is verified. When the user account has the quick battery replacement function enabled, the account balance is verified. When the balance of the user account is greater than or equal to the cost required for this battery replacement, the empty battery compartment in the battery replacement cabinet is opened. When the balance of the user account is less than the cost required for this battery replacement, a balance insufficient prompt is popped up on the screen of the battery replacement cabinet.

[0012] Further, after the shared battery is placed in the empty battery compartment, the control system of the battery replacement cabinet performs a secondary verification on the number of the shared battery placed in the empty battery compartment. After the verification passes, the shared battery is charged.

[0013] Further, the secondary verification of the number of the shared battery placed in the empty battery compartment includes: Performing a consistency verification on the number of the shared battery placed in the empty battery compartment and the number of the shared battery connected to the control system of the battery replacement cabinet; If they are consistent, charging starts normally; If they are inconsistent, a battery error prompt is popped up on the screen of the battery replacement cabinet, and the door of the battery compartment is reopened.

[0014] Further, it also includes: After the control system of the battery replacement cabinet opens the empty battery compartment in the battery replacement cabinet, if no shared battery is detected in the empty battery compartment within a preset time or the management device of the shared battery waiting for the empty battery compartment is disconnected from the control system of the battery replacement cabinet, the current battery replacement process is exited; When the user replaces the battery next time, the opened empty battery compartment is preferentially specified.

[0015] Another technical solution of the present invention is as follows: A convenient battery replacement system for shared electric vehicles, which is used to execute any one of the above-mentioned convenient battery replacement methods for shared electric vehicle batteries, includes: a shared battery and a battery replacement cabinet. The shared battery is equipped with a management device, and the battery replacement cabinet is equipped with a control system. The management device can communicate with the control system.

[0016] Advantages of the present invention: When the shared battery meets the battery replacement conditions, the management device of the shared battery and the control system of the battery replacement cabinet perform wireless communication in advance and perform corresponding verification work, which greatly improves the use efficiency. It eliminates the process of the user taking out the mobile phone to scan the code and the operations and waiting processes after scanning the code, greatly saving the user's battery replacement time, and shortening the traditional battery replacement time from 60 - 120s to about 30s. Description of the Drawings

[0017] Figure 1 It is a flowchart of a convenient battery replacement method for shared batteries of electric vehicles in the present invention. Specific implementation manners

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0019] In the technical solution of the present invention, Figure 1 It is a flowchart provided according to a convenient battery replacement method for shared batteries of electric vehicles. As Figure 1 shown, it includes: S10: When the discharge interface of the shared battery is disconnected from the electric vehicle, the shared battery management device determines whether to search for a battery replacement cabinet within a preset distance according to the current power of the shared battery.

[0020] Among them, the management device of the shared battery can be a BMS device or a processor connected to the BMS device, and has a wireless communication function, which can be Bluetooth communication, WIFI communication, etc., and can communicate with the control system of the battery replacement cabinet. The preset range can be the set communication connection range, such as 1 meter / 3 meters / 5 meters / 10 meters, etc.

[0021] The management device of the shared battery installed in the electric vehicle detects the real-time power of the shared battery. When the discharge interface of the shared battery is disconnected from the electric vehicle, the management device of the shared battery searches for a battery replacement cabinet within the preset range.

[0022] Therefore, the shared battery management device can detect the connection state between the discharge interface of the shared battery and the electric vehicle. At the same time, the shared battery management device can set data such as the default battery replacement power value and the search distance range of the battery.

[0023] When there is at least one empty battery compartment and at least one battery compartment equipped with a fully charged shared battery in the battery replacement cabinet, the control system of the battery replacement cabinet can be searched by the management device of the shared battery for subsequent communication and rapid battery replacement.

[0024] The above-mentioned management device of the shared battery, the control system of the battery replacement cabinet, and the management platform are all conventional technical means in the art, so they will not be elaborated here.

[0025] It should be noted that when the shared battery management device detects that the connection between the shared battery and the electric vehicle is disconnected, that is, when the shared battery management device detects that the discharge port of the shared battery is disconnected, it is determined that the user needs to perform a battery replacement operation. At the same time, it can also be that the user makes a reservation on the mobile phone software or applet. During the reserved time period, the user drives the electric vehicle to the vicinity of any battery replacement cabinet that can meet the battery replacement conditions. At this time, it can also be determined that the user needs to perform a battery replacement operation.

[0026] S20: When the current power of the shared battery is lower than a preset value, the shared battery management device establishes wireless communication with the control system of the nearest battery replacement cabinet within a preset distance and sends a battery replacement request.

[0027] When the management device of the shared battery detects that the current battery power is lower than the preset value, it is considered that the battery has reached the situation where the user needs to replace the battery. Immediately, the shared battery management device communicates with the control system of the nearest battery replacement cabinet within the preset range and sends a battery replacement request.

[0028] It should be noted that the nearest battery replacement cabinet within the preset distance means that if there is more than one battery replacement cabinet of the same type within the preset distance, the shared battery management device only establishes wireless communication with the control system of the nearest battery replacement cabinet and sends a battery replacement request. If there is no replaceable battery in the nearest battery replacement cabinet, after disconnecting the connection, it will establish a connection with the second nearest battery replacement cabinet and send a battery replacement request.

[0029] Among them, the control system of the battery replacement cabinet can be the controller inside the battery replacement cabinet. At the same time, to avoid the situation where the battery replacement cabinet is full and the user cannot replace the battery when the user arrives at the battery replacement cabinet, the battery replacement cabinets that can perform battery replacement can be viewed in the form of a mobile software or applet. For this reason, the control systems of all battery replacement cabinets need to be connected to a unified management platform. The management platform can view and manage the real-time status of each battery replacement cabinet and uniformly manage the user accounts. The above-mentioned shared battery management device, the control system of the battery replacement cabinet, and the management platform are all conventional technical means in this field, so they will not be elaborated here.

[0030] S30: According to the battery replacement request, the control system of the battery replacement cabinet verifies the real-time status of the shared battery and the user account. After the verification is passed, an empty battery compartment in the battery replacement cabinet is opened.

[0031] The control system of the battery replacement cabinet determines the number of the shared battery to be replaced according to the battery replacement request sent by the management device of the shared battery. Specifically, the battery replacement request needs to include the number and real-time status information of the shared battery to be replaced. The control system of the battery replacement cabinet analyzes the battery replacement request to obtain the corresponding number and the real-time status of the shared battery.

[0032] Determine the user account and battery basic parameters corresponding to the shared battery number. All user account data and battery basic parameters are stored in the management platform. The control system of the battery swapping cabinet searches for the user account and battery basic parameters corresponding to the shared battery number in the management platform according to the shared battery number. It should be noted that each shared battery number corresponds to at most one user account, and the same user account can correspond to multiple shared battery numbers.

[0033] That is to say, the same user can rent multiple shared batteries as needed. When the shared battery is in the battery swapping cabinet, there is no corresponding user account for this shared battery. When each user account rents a shared battery, the shared battery number will be associated with its own account.

[0034] Perform safety verification on the shared battery according to the battery basic parameters and real-time status of the shared battery.

[0035] Among them, the battery basic parameters include: the model, production date, and available days of the shared battery; The real-time status of the shared battery includes: the current battery level, real-time battery voltage, and real-time battery temperature; Verify the available days, real-time battery voltage, and real-time battery temperature of the shared battery; When the available days are equal to 0, or the real-time battery voltage or real-time battery temperature is not within the safe range, the safety verification fails; The control system of the battery swapping cabinet stops charging the shared battery that fails the safety verification and notifies the management staff to replace the shared battery. The notification can be carried out through the management platform, and the abnormal information is displayed in the management platform.

[0036] It should be noted that even if the verification fails, it does not prevent the control system of the battery swapping cabinet from performing identity verification and balance verification on the user account.

[0037] After the battery safety verification is completed, perform identity verification and balance verification on the user account. After the verification passes, open the empty battery compartment in the battery swapping cabinet.

[0038] The specific verification process is as follows: Verify whether the user account is in a normal state and whether the battery swapping monthly subscription function is enabled. When the user account is in a normal state and the battery swapping monthly subscription function is enabled, open the empty battery compartment in the battery swapping cabinet.

[0039] When the user account does not have the battery swapping monthly subscription function enabled, verify whether the user account has the quick battery swapping function enabled. When the user account does not have the quick battery swapping function enabled, a battery swapping confirmation button will pop up on the screen of the battery swapping cabinet. When the user clicks the confirmation button, perform account balance verification.

[0040] When the quick battery replacement function is activated for the user account, the account balance is verified.

[0041] When the balance of the user account is greater than or equal to the cost of this battery replacement, the empty battery compartment in the battery replacement cabinet is opened; when the balance of the user account is less than the cost of this battery replacement, an insufficient balance prompt will pop up on the screen of the battery replacement cabinet.

[0042] During the user account verification process, the user account corresponding to the shared battery will first be verified to see whether the monthly subscription function has been activated. The monthly subscription user will pass the verification immediately and open the empty battery compartment.

[0043] Non-monthly users will then verify whether the quick battery swap function is enabled in their user account. If so, the verification will be passed if the account balance in the user account is sufficient for the battery swap amount. If so, the user will pass the verification. If the quick battery swap function is not enabled, a dialog box will pop up on the screen of the battery swap cabinet, welcoming the user and asking whether the user wants to swap the battery. The user will manually confirm the battery swap, and then the account balance will be verified and the fee will be automatically deducted.

[0044] If the account balance is insufficient, a reminder of insufficient balance will pop up on the screen of the battery swap cabinet, prompting the user to recharge. Click the screen again to pop up the recharge QR code. Users can also recharge by themselves on mobile software or mini programs. If the user clicks "Cancel" to cancel the battery swap, or does not operate within the specified time (such as 3 minutes), the control system of the battery swap cabinet will be reset.

[0045] After the user replaces the battery, the control system of the battery exchange cabinet detects that the replacement shared battery is taken out of the battery compartment, matches the number of the replacement shared battery with the account information, and cancels the correspondence between the number of the previous shared battery and the account information.

[0046] S40: After the control system of the battery swap cabinet detects that the shared battery is placed in an empty battery compartment and the compartment door is closed, it opens another battery compartment in the battery swap cabinet that contains a replacement shared battery.

[0047] The control system of the battery exchange cabinet performs a secondary verification on the serial number of the shared battery placed in the empty battery compartment. After the verification is passed, the shared battery is charged.

[0048] Verify the consistency between the serial number of the shared battery placed in the empty battery compartment and the serial number of the shared battery connected to the control system of the battery swap cabinet; If they are consistent, charging starts normally; If there is any inconsistency, a battery error prompt will pop up on the screen of the battery swap cabinet and the battery compartment door will be reopened.

[0049] Meanwhile, to avoid misidentification by the control system of the electrical cabinet or the user temporarily canceling the battery replacement plan, when the control system of the battery replacement cabinet opens the empty battery compartment in the battery replacement cabinet and no shared battery is detected in the empty battery compartment within a preset time (such as 3 minutes) or the management device of the shared battery waiting for the empty battery compartment is disconnected from the control system of the battery replacement cabinet, the current battery replacement process is exited, that is, at this time, the corresponding relationship between the user account and the shared battery is not changed, and the balance of the user account is not deducted. At the same time, the opened empty battery compartment is preferentially designated when the user replaces the battery next time to ensure that only the door of one empty battery compartment is opened each time the user replaces the battery.

[0050] After the user takes out the available shared battery and closes the compartment door, the entire battery replacement process is completed.

[0051] In another technical solution of the present invention, a convenient battery replacement system for electric vehicle shared batteries is provided. This system is used to execute any one of the above-mentioned convenient battery replacement methods for electric vehicle shared batteries, and includes: shared batteries and a battery replacement cabinet. The shared battery is equipped with a management device, and the battery replacement cabinet is equipped with a control system. The management device can communicate with the control system.

[0052] The specific implementation process and effective effects of this technical solution are the same as those of the convenient battery replacement method for electric vehicle shared batteries, so they will not be elaborated here.

[0053] Finally, it should be noted that the above specific implementation manners are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
