Description

Technical Field

[0001] The present disclosure generally relates to the field of charging, and more particularly to a charging device, a method for determining a connection status of a charging device, and a computer-readable storage medium. Background Art

[0002] In recent years, building safety accidents caused by charging electric bicycles have attracted increasing attention. Consequently, many residential communities prohibit residents from bringing electric bicycles or their batteries home for charging, requiring them to be charged at centralized charging cabinets. To meet user demand for faster charging, many charging cabinets have developed battery swapping capabilities. This allows users to simply place a battery to be charged in a compartment and simultaneously remove a fully charged new battery, allowing them to be used immediately without waiting for the old one to fully charge. Both traditional charging cabinets and those with battery swapping capabilities offer significant convenience to users, but poor management can pose significant safety risks. Minimizing operating costs while ensuring safe operation of charging cabinets presents a challenge for designers. Summary of the Invention

[0003] To improve computing performance in an integrated circuit, embodiments of the present disclosure provide a charging device, a method for determining a connection status of the charging device, and a computer-readable storage medium.

[0004] In a first aspect of the present disclosure, a charging device is provided. The charging device is suitable for charging one or more batteries and includes: an electrical compartment, including: a power distribution unit coupled to a power source; a power module coupled to the power distribution unit and configured to adapt a voltage from the power source; and a control board coupled to the power distribution unit and configured to detect a signal from a corresponding battery; and a battery compartment, coupled to the electrical compartment and including one or more slots suitable for accommodating the battery, each slot including: a first interface, the first interface suitable for coupling the corresponding battery to the power module via a first connection; and a second interface, the second interface suitable for coupling the corresponding battery to the control board via a second connection.

[0005] According to the implementation method of the present disclosure, by concentrating the power module and the control board in the electrical compartment, centralized control of the charging device can be achieved, and at the same time, the number of components in the charging device can be effectively reduced to reduce the overall operating cost of the charging device.

[0006] In some implementations, the charging device further includes a wiring detection device configured to: obtain a first power voltage of the corresponding battery via the first interface; obtain a first signal voltage of the corresponding battery via the second interface; and determine the wiring status of the charging device based on the first power voltage and the first signal voltage. In this manner, the power voltage and signal voltage of the battery can be used to conveniently determine whether the charging device is incorrectly wired. Since the power voltage and signal voltage are readily available, this approach does not add additional cost to the charging device.

[0007] In some implementations, the wiring detection device is further configured to, in response to a difference between the first power voltage and the first signal voltage being greater than a first threshold, disable use of the battery compartment. In this way, when a wiring error occurs, this error can be accurately detected, thereby effectively preventing undercharging or overcharging of the battery.

[0008] In some implementations, the connection detection device is further configured to: in response to the difference between the first power voltage and the first signal voltage being no greater than a first threshold, change the voltage of the corresponding battery via the first interface; obtain a second power voltage of the corresponding battery via the first interface; obtain a second signal voltage of the corresponding battery via the second interface; and determine the connection status of the charging device based on the second power voltage and the second signal voltage. If the connection of one battery compartment is swapped with another compartment and the voltages of the two compartments are the same, an inaccurate judgment may result. In this way, this situation can be effectively avoided.

[0009] In some implementations, the wiring detection device is further configured to, in response to a difference between the second power voltage and the second signal voltage being greater than a second threshold, disable use of the battery compartment. In this manner, wiring errors in the compartment can be promptly detected, improving the reliability of the charging device during the charging process.

[0010] In some implementations, the connection detection device is further configured to: in response to the difference between the second power voltage and the second signal voltage being no greater than a second threshold, maintain use of the battery compartment. In this manner, the connection status of the compartment can be effectively determined.

[0011] In a second aspect of the present disclosure, a method for determining a wiring status of a charging device is provided. The charging device includes a compartment suitable for accommodating one or more batteries. The method includes: obtaining a first power voltage of a corresponding battery via a first interface of the compartment, wherein the first interface couples the corresponding battery to a power module via a first connection, and the power module is configured to adapt to a voltage from a power supply; obtaining a first signal voltage of the corresponding battery via a second interface of the compartment, wherein the second interface couples the corresponding battery to a control board via a second connection, and the control board is configured to detect a signal of the corresponding battery; and determining the wiring status of the charging device based on the first power voltage and the first signal voltage.

[0012] In some implementations, determining the connection status of the charging device includes: in response to a difference between the first power voltage and the first signal voltage being higher than a first threshold, stopping use of the compartment where the battery is located.

[0013] In some implementations, determining the connection status of the charging device includes: in response to the difference between the first power voltage and the first signal voltage being no higher than a first threshold, changing the voltage of the corresponding battery via the first interface; obtaining a second power voltage of the corresponding battery via the first interface; obtaining a second signal voltage of the corresponding battery via the second interface; and determining the connection status of the charging device based on the second power voltage and the second signal voltage.

[0014] In some implementations, determining the connection status of the charging device includes: in response to a difference between the second power voltage and the second signal voltage being higher than a second threshold, stopping use of the compartment where the battery is located.

[0015] In some implementations, determining the connection status of the charging device includes: in response to a difference between the second power voltage and the second signal voltage being no greater than a second threshold, maintaining use of the compartment where the battery is located.

[0016] In a third aspect of the present disclosure, a computer-readable storage medium is provided, on which a computer program is stored. When the program is executed by a processor, the method of the second aspect of the present disclosure is implemented.

[0017] These and other aspects of the present disclosure will become apparent from the following description of the embodiment(s). BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The above and other features, advantages and aspects of the embodiments of the present disclosure will become more apparent with reference to the following detailed description in conjunction with the accompanying drawings. In the accompanying drawings, the same or similar reference numerals represent the same or similar elements. The accompanying drawings are not necessarily drawn to scale, wherein:

[0023] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0024] In the description of the embodiments of the present disclosure, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to." The term "based on" should be understood as "based at least in part on." The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment." The terms "first," "second," etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0025] As mentioned above, a charging device is proposed in the prior art. Figure 1 To describe the charging device 1' in the prior art. As shown in the figure, this charging device 1' generally includes an electrical compartment 10' and a battery compartment 20', wherein the battery compartment 20' includes a plurality of compartments 22' for accommodating batteries to be charged. As shown, in the existing charging device 1', the electrical compartment 10' includes a power distribution unit 12' for providing an external power source 2' to the corresponding compartment 22'. Each compartment 22' is equipped with a corresponding power module 14' and a control board 16', wherein the power module 14' is coupled to the power distribution unit 12' and adapts the voltage of the power source 2' to a suitable voltage, thereby providing a voltage output for the battery in the compartment 22'. The control board 16' is used to couple the power distribution unit 12' with the battery in the compartment 22' and can detect the signal of the corresponding battery. In this existing solution, since each compartment 22' corresponds to a corresponding power module 14' and a control board 16', it can be called a distributed architecture.

[0026] With this distributed architecture, the number of power modules 14' and control boards 16' must be consistent with the number of slots 22' in the charging device 1'. Each slot 22' requires a corresponding control board 16' to manage and control the corresponding slot 22'. Centralized management is impossible, and the charging device 1' requires a large number of hardware circuits of the control board 16', resulting in a low degree of integration, which increases the cost of the entire charging device 1'. In addition, the wiring of the charging device 1' using a distributed architecture is relatively messy, the overall maintenance interface is messy, and the manufacturability is poor. In traditional solutions, the number of power modules 14' and control boards 16' will increase with the increase in slots 22', which not only leads to increased costs, but also increases the space required for the charging device. This actually hinders the promotion of the charging device 1', because many scenarios do not allow the charging device 1' to be too large.

[0027] At least in order to solve the above problems, the embodiment of the present disclosure provides a charging device 1 using a centralized architecture. Figure 2 to describe some exemplary embodiments of the present disclosure.

[0028] like Figure 2 As shown, the charging device 1 generally comprises an electrical compartment 10 and a battery compartment 20. The electrical compartment 10 contains electrical components that provide electrical support for the battery compartment 20. The battery compartment 20 is coupled to the electrical compartment 10 and includes multiple slots 22 for accommodating batteries to be charged. Users can place batteries to be charged into corresponding battery compartments 20 for charging.

[0029] Specifically, the electrical warehouse 10 includes a power distribution unit 12, a power module 14 and a control board 16. The power distribution unit 12 is coupled to an external power source 2, and can supply power from the power source 2 to other components. The power distribution unit 12 can provide power protection for the electrical warehouse 10 to prevent the power of the electrical warehouse 10 from being too large. In addition, one or more user interfaces can be provided on the power distribution unit 12 to facilitate the user to operate the charging device 1 through these interfaces to achieve the purpose of charging the battery to be charged. The power source 2 can be a commercial power source of various standards, such as alternating current with a voltage of 220V and a frequency of 50Hz. It should be understood that the values ​​listed here are merely indicative and not restrictive. The type of power source 2 can be determined according to the actual use environment. For example, in other embodiments, the power source 2 can also be direct current.

[0030] Continue to refer Figure 2 The power module 14 is coupled to the power distribution unit 12 and adapts the voltage from the power source 2. The voltage adapted by the power module 14 is a voltage of suitable value for charging the batteries in the battery compartment 20. Such a setting can provide a stable and reliable voltage for the batteries to be charged. Figure 2As shown, the electrical compartment 10 is also provided with a control board 16, which is coupled to the power distribution unit 12 on one hand, and coupled to each battery in the battery compartment 20 on the other hand, and functions to detect the signals of the corresponding batteries.

[0031] The battery compartment 20 according to embodiments of the present disclosure will be introduced below with continued reference to Figure 2 Figure 2 In the figures, the power transmission lines in the charging device 1 are represented by solid lines, and the signal transmission lines in the charging device 1 are represented by dashed lines. As shown, the battery compartment 20 is provided with a plurality of bays 22, although Figure 2 Four bays are shown in the figures, but it should be understood that this is merely illustrative and not limiting. Depending on the actual usage requirements, more or fewer bays 22 can be provided in the battery compartment 20 of the charging device 1 to provide charging services for an appropriate number of batteries. In more embodiments, the number of bays 22 is also variable, which can be flexibly adjusted according to different requirements.

[0032] As Figure 2 shown, each bay 22 includes a first interface 221 and a second interface 222. In specific embodiments, the first interface 221 can be an interface for transmitting power, for coupling the battery contained in the corresponding bay 22 to the power module 14 via a first wiring 23. In some embodiments, the first wiring 23 can be a power line that provides charging power for this bay 22. The second interface 222 can be an interface for transmitting signals, for coupling the battery contained in the corresponding bay 22 to the control board 16 via a second wiring 24. In some embodiments, the second wiring 24 can be an R485 signal line known in the art.

[0033] According to embodiments of the present disclosure, the power module 14 and the control board 16 are uniformly provided in the electrical compartment 10 to provide power and signal transmission for the bays 22 in the battery compartment 20. As the charging demand is growing, more and more bays 22 need to be provided in the charging device 1 to meet these demands. In this case, compared to existing solutions, the number of power modules and control boards in embodiments of the present disclosure does not increase accordingly, avoiding excessive number of hardware of the charging device, not only effectively controlling the cost, but also avoiding excessive size of the charging device 1, thus being more applicable to more use scenarios, meeting the development trend of the charging device 1.

[0034] In embodiments of the present disclosure that adopt a centralized architecture, since each bay 22 does not need to be provided with a power module and a control board as in Figure 1 ​The distributed architecture shown in the figure is not equipped with corresponding power modules and control boards. Instead, all the positions 22 are connected to a unified power module 14 and control board 16 through corresponding power lines and signal lines. Therefore, during the construction and maintenance of the charging device 1, there is a risk of incorrect wiring. In this way, for a specific position 22, when the battery to be charged is connected to the position 22, the battery voltage detected by its signal line may be different from the battery voltage detected by the power line. For example, the actual voltage is 30V, but the voltage detected by the signal line is only 20V. If the battery is charged at 20V, it may cause overcharging. Similarly, it may also cause undercharging. Therefore, for a centralized architecture, it is necessary to monitor the wiring status in the charging device 1 in real time to avoid undercharging or overcharging caused by wiring errors, thereby avoiding greater safety hazards.

[0035] In some embodiments, the charging device 1 may further include a wiring detection device 18. The wiring detection device 18 may be used to determine the status of wiring within the charging device 1.

[0036] Reference below Figure 3 1. The method 300 for determining the connection status of a charging device 1 according to an embodiment of the present disclosure is described below. The method 300 can be used to determine whether the connection of each compartment 22 in the charging device 1 is correct. The method 300 can be performed by the connection detection device 18 in the charging device 1.

[0037] For a certain position 22, in block 302, the first power voltage U of the corresponding battery is obtained via the first interface 221 of the position 22. P1 In addition, in block 304, the first signal voltage U of the corresponding battery is obtained via the second interface 222 of the bin 22. S1 Then, in block 305, based on the first power voltage U P1 and the first signal voltage U S1 To determine the connection status of the charging device 1. After the determination step shown in box 305, it can be decided whether to keep the use of the storage space 22 (box 316) or stop the use of the storage space 22 (box 318) according to the determined connection status of the charging device 1. It should be noted that the acquisition of the first power voltage U represented by box 302 P1 The step and block 304 represent obtaining the first signal voltage U S1 There is no difference in the order of the steps, and they can be flexibly adjusted according to actual conditions.

[0038] In the charging device 1, if the connections in the compartment 22 in the battery compartment 20 are correct, the first power voltage U of the corresponding battery is obtained via the first interface 221. P1The first signal voltage U of the corresponding battery is obtained from the second interface 222 S1 This is because both methods reflect the power supply voltage in the bin 22. Therefore, for a certain bin 22, as shown in block 306, the first power voltage U P1 and the first signal voltage U S1 If the first power voltage U P1 and the first signal voltage U S1 If the difference Δ1 between the two is higher than a first threshold, it means that the difference between the two is too large, which indicates that the wiring of the bin 22 is wrong. Figure 3 As shown, it is necessary to stop using the corresponding position 22 to avoid charging anomalies caused by wiring errors. This wiring error may be caused by the power line of the corresponding position 22 being connected to the power line of another position 22, or it may be caused by the signal line of the corresponding position 22 being connected to the signal line of another position 22. In either case, the charging process of the corresponding position 22 must be stopped immediately to ensure the safety of the charging device 1. In a further embodiment, such error conditions can also be fed back to the maintainer of the charging device 1 to notify them to perform maintenance on the charging device 1 immediately.

[0039] If the first power voltage U obtained via the first interface 221 is determined at block 306 P1 and the first signal voltage U obtained via the second interface 222 S1 If the difference Δ1 is not higher than the first threshold, it basically indicates that the wiring of the bin 22 is correct. However, there is a possibility that if the wiring of a bin 22 is swapped with the wiring of another bin 22, and the voltages of the two bins happen to be basically the same at the time of the judgment step shown in block 306, then this wiring error cannot be simply discovered by the above steps. In order to detect this wiring error, you can also use Figure 3 The method shown in further determines the connection status of the charging device 1 .

[0040] refer to Figure 3 If the first power voltage U is determined in block 306 P1 and the first signal voltage U S1 If the difference Δ1 is not greater than the first threshold, further determination is required to ensure the accuracy of the detection step. At this point, method 300 proceeds to block 308 , where the voltage of the corresponding battery in bin 22 needs to be changed via first interface 221 , so that the voltage of that bin 22 is no longer the same as that of another bin 22 with the same voltage. In some embodiments, the voltage of the battery in bin 22 can be increased. In other embodiments, the voltage of the battery in bin 22 can also be decreased.

[0041] Then, in block 310 , the second power voltage U of the corresponding battery is obtained via the first interface 221 . P2 In addition, in block 312 , the second signal voltage U of the corresponding battery is obtained via the second interface 222 . S2 It should be noted that the block 310 represents the acquisition of the second power voltage U P2 The step and block 312 represent obtaining the second signal voltage U S2 There is no difference in the order of the steps, and they can be flexibly adjusted according to the actual situation. P2 and the second signal voltage U S2 The difference Δ2 is judged to determine whether the difference Δ2 is higher than a second threshold.

[0042] Similar to the above block 306, if it is determined in block 314 that the difference Δ2 is not higher than the second threshold value, this indicates that even if the voltage of the bin 22 is changed, the second power voltage U is obtained after the change. P2 With the second signal voltage U S2 It can still be considered equal, which can determine that the wiring of the bin 22 is correct. At this time, the use of the bin 22 can be maintained as shown in box 316. On the other hand, if it is determined in box 314 that the difference Δ2 is higher than the second threshold, it can be determined that there is a problem with the wiring of the bin 22, that is, the wiring of the two bins mentioned above is swapped and the voltages of the two bins are exactly the same. At this time, as shown in box 318, the use of the bin 22 should also be stopped immediately to avoid charging abnormalities due to wiring errors. In a further embodiment, such an error situation can also be fed back to the maintainer of the charging device 1 to notify him to maintain the charging device 1.

[0043] According to the embodiments of the present disclosure, various possible situations are taken into consideration during judgment, thereby ensuring that the determination of the connection status in the centralized architecture is accurate, thereby guaranteeing the safety of the charging device.

[0044] In some embodiments, the first threshold value relied upon for determination in block 306 may be the same as the second threshold value relied upon for determination in block 314. In other embodiments, the first threshold value and the second threshold value may be different.
