Description

Charging device, method of determining connection state of charging device, and computer-readable storage medium

Technical Field

The present disclosure generally relates to the field of charging. More particularly, the present disclosure relates to a charging device, a method of determining a wiring state of the charging device, and a computer-readable storage medium.

Background

In recent years, building safety accidents caused by charging of electric bicycles are attracting more and more attention. Therefore, many communities of residents prohibit bringing electric bicycles or their batteries back to residents' homes for charging, but rather must charge at a centralized charging cabinet. In order to meet the requirement of a user on quick charging, a plurality of charging cabinets develop a function of changing batteries, namely, the user directly puts the batteries to be charged into a bin for charging and takes out the fully charged new batteries, so that the new batteries can be used in time without waiting for the full charge of the old batteries. The traditional charging cabinet or the charging cabinet with the battery replacement function provides great convenience for users, but great potential safety hazards can be brought once the management is poor. How to reduce the operation cost of the charging cabinet to a greater extent while ensuring the safe operation thereof is a challenge for designers.

Disclosure of Invention

To improve computational performance in an integrated circuit, embodiments of the present disclosure provide a charging device, a method of determining a wiring state of a charging device, and a computer-readable storage medium.

In a first aspect of the present disclosure, a charging device is provided. The charging device is adapted to charge one or more batteries and comprises: an electrical bin comprising: 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 signals of the respective batteries; and a battery compartment coupled to the electrical compartment and including one or more compartments adapted to hold the battery, each compartment including: a first interface adapted to couple a respective battery to the power module via a first connection; and a second interface adapted to couple the respective battery to the control board via a second wire.

According to the implementation mode disclosed by the disclosure, the power module and the control board are integrated in the electric bin, so that the integrated control of the charging device can be realized, and meanwhile, the number of components in the charging device can be effectively reduced, so that the overall operation cost of the charging device is reduced.

In some implementations, the charging device further includes a wiring detection device configured to: obtaining a first power voltage of a corresponding battery via the first interface; acquiring a first signal voltage of a corresponding battery through the second interface; and determining a wiring state of the charging device based on the first power voltage and the first signal voltage. In this way, it is possible to easily determine whether or not the wiring of the charging device is erroneous by the power voltage and the signal voltage of the battery. This does not add any further cost to the charging device, since the power voltage and the signal voltage are readily available.

In some implementations, the wiring detection apparatus is further configured to: in response to a difference between the first power voltage and the first signal voltage being above a first threshold, ceasing use of the bin in which the battery is located. In this way, when wiring is faulty, such a faulty state can be accurately known, thereby effectively avoiding undercharging or overcharging of the battery.

In some implementations, the wiring detection apparatus is further configured to: responsive to a difference between the first power voltage and the first signal voltage not being above a first threshold, changing a voltage of the respective battery via the first interface; obtaining a second power voltage of the corresponding battery via the first interface; acquiring a second signal voltage of the corresponding battery through the second interface; and determining a wiring state of the charging device based on the second power voltage and the second signal voltage. Inaccurate determinations may result if the connections of one bin are swapped with the connections of another bin and the voltages of the two bins are the same. In this way, the occurrence of such a situation can be effectively avoided.

In some implementations, the wiring detection apparatus is further configured to: and stopping the use of the bin in which the battery is positioned in response to the difference value between the second power voltage and the second signal voltage being higher than a second threshold value. In this way, the wiring error of the bin can be found in time, and the reliability of the charging device in the charging process is improved.

In some implementations, the wiring detection apparatus is further configured to: responsive to a difference between the second power voltage and the second signal voltage not being above a second threshold, use of the bin in which the battery is located is maintained. In this way, the wiring state of the bin can be effectively judged.

In a second aspect of the present disclosure, a method of determining a wiring state of a charging device is provided. The charging device includes a bay adapted to receive one or more batteries. The method comprises the following steps: obtaining a first power voltage of the respective battery via a first interface of the bin, wherein the first interface couples the respective battery via a first connection to a power module configured to adapt a voltage from a power source; obtaining a first signal voltage of the respective battery via a second interface of the bin, wherein the second interface couples the respective battery to a control board via a second connection, the control board configured to detect a signal of the respective battery; and determining a wiring state of the charging device based on the first power voltage and the first signal voltage.

In some implementations, determining the wiring state of the charging device includes: in response to a difference between the first power voltage and the first signal voltage being above a first threshold, ceasing use of the bin in which the battery is located.

In some implementations, determining the wiring status of the charging device includes: responsive to a difference between the first power voltage and the first signal voltage not being above a first threshold, changing a voltage of the respective battery via the first interface; obtaining a second power voltage of the corresponding battery via the first interface; acquiring a second signal voltage of the corresponding battery through the second interface; and determining a wiring state of the charging device based on the second power voltage and the second signal voltage.

In some implementations, determining the wiring status of the charging device includes: and stopping the use of the bin in which the battery is located in response to the difference between the second power voltage and the second signal voltage being higher than a second threshold.

In some implementations, determining the wiring status of the charging device includes: responsive to a difference between the second power voltage and the second signal voltage not being above a second threshold, use of the bin in which the battery is located is maintained.

In a third aspect of the disclosure, a computer-readable storage medium is provided, on which a computer program is stored which, when executed by a processor, implements the method of the second aspect of the disclosure.

These and other aspects of the disclosure will be apparent from and elucidated with reference to the embodiment(s) described hereinafter.

Detailed Description

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more complete and thorough understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.

In describing embodiments of the present disclosure, the terms "include" and its derivatives should be interpreted as being inclusive, i.e., "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," and the like may refer to different or the same object. Other explicit and implicit definitions are also possible below.

As described above, a charging device is proposed in the related art. A charging device 1' in the related art is described below with reference to fig. 1. As shown, such a charging device 1 ' generally comprises an electrical compartment 10 ' and a battery compartment 20 ', wherein the battery compartment 20 ' comprises a plurality of compartments 22 ' for accommodating batteries to be charged. As shown, in the existing charging device 1 ', the electrical bay 10 ' includes a power distribution unit 12 ' for providing an external power source 2 ' to the corresponding bay 22 '. Each bay 22 ' is equipped with a respective power module 14 ' and control board 16 ', where the power module 14 ' is coupled to the power distribution unit 12 ' and adapts the voltage of the power source 2 ' to the appropriate voltage to provide a voltage output for the batteries in the bay 22 '. Control board 16 ' is used to couple power distribution unit 12 ' with the batteries within bin 22 ' and may detect signals of the respective batteries. In existing such schemes, each bin 22 ' may be referred to as a distributed architecture, since it corresponds to a respective power module 14 ' and control board 16 '.

By adopting the distributed architecture, the number of the power modules 14 'and the control boards 16' needs to be consistent with the number of the bins 22 'in the charging device 1', each bin 22 'needs to be controlled by the corresponding control board 16' to control the corresponding bin 22 ', centralized management cannot be achieved, the number of hardware circuits of the control boards 16' needed by the charging device 1 'is large, the integration degree is low, and the cost of the whole charging device 1' is increased. In addition, the charging device 1' adopting the distributed architecture has relatively scattered wiring, a scattered overall maintenance interface and poor manufacturability. In the conventional solution, the number of power modules 14 ' and control boards 16 ' increases with the increase of the bin 22 ', which not only results in increased cost, but also causes the space occupied by the charging device to become large, which actually hinders the popularization of the charging device 1 ', because the size of the charging device 1 ' is not allowed to be too large in many situations.

At least to solve the above problems, embodiments of the present disclosure provide a charging device 1 employing a centralized architecture. Some illustrative embodiments of the present disclosure are described below with reference to fig. 2.

As shown in fig. 2, the charging device 1 generally includes an electric compartment 10 and a battery compartment 20. The electrical compartment 10 includes electrical components therein for providing electrical support to the battery compartment 20. Battery compartment 20 is coupled to electrical compartment 10 and includes a plurality of bays 22, which bays 22 may be used to house batteries to be charged. The user can put the battery to be charged into the corresponding battery compartment 20 for charging.

Specifically, the electrical cabinet 10 includes a power distribution unit 12, a power module 14, and a control board 16. The power distribution unit 12 is coupled to the 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 compartment 10 to prevent the electrical compartment 10 from being overpowered. In addition, one or more user interfaces may be provided on the power distribution unit 12, so that the user can operate the charging device 1 through the interfaces conveniently to charge the battery to be charged. The power supply 2 may be mains power of various standards, for example, alternating current of 220V and 50 Hz. It is to be understood that the numerical values set forth herein are exemplary only and are not limiting. The type of power source 2 may be determined according to the actual environment of use, for example, in other embodiments, the power source 2 may also be direct current.

With continued reference to fig. 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 with a suitable value for charging the battery in the battery compartment 20, and such an arrangement can provide a stable and reliable voltage for the battery to be charged. As shown in fig. 2, a control board 16 is also arranged in the electrical compartment 10, the control board 16 being coupled on the one hand to the power distribution unit 12 and on the other hand to the individual batteries in the battery compartment 20, and functioning to detect the signals of the respective batteries.

With continued reference to fig. 2, a battery compartment 20 according to an embodiment of the present disclosure is described. In fig. 2, power transmission lines in the charging device 1 are indicated by solid lines, and signal transmission lines in the charging device 1 are indicated by broken lines. As shown, a plurality of bins 22 are provided within the battery compartment 20, and although four bins are shown in fig. 2, it should be understood that this is illustrative only and not limiting. More or fewer bays 22 may be provided in the battery compartment 20 of the charging device 1 to provide charging services for an appropriate number of batteries, depending on the actual usage requirements. In further embodiments, the number of bins 22 is also variable, which can be flexibly adjusted to different needs.

As shown in fig. 2, each bin 22 includes a first interface 221 and a second interface 222. In a particular embodiment, the first interface 221 may be an interface for transmitting power for coupling the batteries contained in the respective bins 22 to the power module 14 via the first wiring 23. In some embodiments, the first connection 23 may be a power line that provides charging power to the bin 22. Second interface 222 may be an interface for transmitting signals for coupling the batteries contained in the respective bins 22 to control board 16 via second wiring 24. In some embodiments, the second connection 24 may be an R485 signal line as known in the art.

According to an embodiment of the present disclosure, a power module 14 and a control board 16 are collectively disposed within the electrical compartment 10 to provide power and signal transmission to the compartment 22 within the battery compartment 20. As the demand for charging increases, more and more bays 22 in the charging device 1 are required to meet these demands. In this case, compared with the existing scheme, the number of the power modules and the number of the control boards in the embodiment of the present disclosure are not increased accordingly, the number of the hardware of the charging device is avoided being too large, not only the cost can be effectively controlled, but also the size of the charging device 1 can be avoided being too large, so that the charging device is more suitable for more use scenarios, and the development trend of the charging device 1 is satisfied.

In the embodiment of the present disclosure that employs a centralized architecture, since each bay 22 is not equipped with a corresponding power module and control board as in the distributed architecture shown in fig. 1, but all bays 22 are connected to the unified power module 14 and control board 16 through corresponding power lines and signal lines, respectively, there is a risk that the wiring may be misconnected during the setup and maintenance of the charging device 1. Thus, for a particular bay 22, the battery voltage detected by the signal line may be different from the battery voltage detected by the power line when the battery to be charged is accessed into that bay 22. For example, the actual voltage is 30V, and the voltage detected by the signal line is only 20V, which may cause overcharging if the battery is charged at 20V. Similarly, undercharging may also result. Therefore, for the centralized architecture, the wiring state in the charging device 1 needs to be monitored in real time to avoid insufficient or excessive charging caused by a wiring error, thereby avoiding a greater potential safety hazard.

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

A method 300 of determining the wiring state of the charging device 1 according to an embodiment of the present disclosure is described below with reference to fig. 3. The method 300 may be used to determine whether each bay 22 in the charging device 1 is wired correctly. The method 300 may be performed by the wiring detection device 18 within the charging device 1.

For a bin 22, at block 302, a first power voltage U of the corresponding battery is obtained via the first interface 221 of the bin 22 _P1 . In addition, at block 304, a first signal voltage U of the corresponding battery is obtained via the second interface 222 of the bin 22 _S1 . Then, at block 305, a first power voltage U is based _P1 And a first signal voltage U _S1 The wiring state of the charging device 1 is determined. Following the determination step shown in block 305, it may be decided whether to maintain the use of the bin 22 (block 316) or to stop the use of the bin 22 (block 318) according to the determined wiring state of the charging device 1. In this regard, block 302 is illustratedRepresentative acquisition of the first power voltage U _P1 And the step of obtaining the first signal voltage U as represented by block 304 _S1 The steps of (1) have no difference of sequence, and can be flexibly adjusted according to actual conditions.

In the charging device 1, if the wiring in the bin 22 within the battery compartment 20 is correct, the first power voltage U of the corresponding battery is acquired via the first interface 221 _P1 The second interface 222 obtains the first signal voltage U of the corresponding battery _S1 Should be substantially equal. This is because both of these ways are ways of reflecting the supply voltage in that bin 22. Therefore, for a bin 22, as shown in block 306, a first power voltage U is required _P1 And a first signal voltage U _S1 Difference value Δ of ₁ And judging whether the size is too large. If the first power voltage U _P1 And a first signal voltage U _S1 Difference value Δ of ₁ Above a certain first threshold, it indicates that the difference between the two is too large, which indicates that the wiring of the bin 22 is wrong, and as shown in fig. 3, the use of the bin 22 needs to be stopped, so as to avoid charging abnormality caused by wiring error. Such a wiring error may be due to the power line of the bin 22 being inverted with respect to the power line of another bin 22, or due to the signal line of the bin 22 being inverted with respect to the signal line of another bin 22. In either case, it is necessary to stop the charging process of the corresponding bay 22 immediately in order to ensure the safety of the charging device 1. In a further embodiment, such an error condition may also be fed back to the maintainer of the charging device 1 to inform him to perform maintenance on the charging device 1 immediately.

If it is determined at block 306 that the first power voltage U is obtained via the first interface 221 _P1 And a first signal voltage U acquired via the second interface 222 _S1 Difference value Δ of ₁ Not above the first threshold, this essentially indicates that the wiring of the bin 22 is correct. However, there is a possibility that if the connection of one bin 22 is reversed with the connection of another bin 22 and the voltages of the two bins at the time of the decision step shown in block 306 are exactly substantially the same, the wiring error cannot be simply passed throughStep (c) to discover. In order to detect such a wiring error, the method shown in fig. 3 may be used to further determine the wiring state of the charging device 1.

Referring to fig. 3, if the first power voltage U is determined at block 306 _P1 And a first signal voltage U _S1 Difference value Δ of ₁ Not higher than the first threshold, further judgment is needed to ensure the accuracy of the detection step. At this point, method 300 proceeds to block 308, requiring the voltage of the corresponding cell in bin 22 to be changed via first interface 221 so that the voltage of that bin 22 is no longer the same as another bin 22 having the same voltage. In some embodiments, the battery in the bin 22 may be boosted. In other embodiments, the cells in the bin 22 may also be depressurized.

Subsequently, in block 310, a second power voltage U of the respective battery is obtained via the first interface 221 _P2 . Further, at block 312, a second signal voltage U of the corresponding battery is obtained via the second interface 222 _S2 . It is noted that obtaining the second power voltage U is represented by block 310 _P2 And the step of obtaining the second signal voltage U as represented by block 312 _S2 The steps of (1) have no difference of sequence, and can be flexibly adjusted according to actual conditions. Thereafter, at block 314, the second power voltage U is applied _P2 And a second signal voltage U _S2 Difference value Δ of ₂ Judging the difference value delta ₂ Above some second threshold.

Similar to block 306 above, if the difference Δ is determined at block 314 to be the same as the difference Δ ₂ Not higher than the second threshold, indicating that: even if the voltage of the bin 22 is changed, the second power voltage U is obtained after the change _P2 And a second signal voltage U _S2 Which may still be considered equal, it can be determined that the wiring of the bin 22 is error free. At this point, the use of that bin 22 may be maintained, as indicated at block 316. On the other hand, if it is determined at block 314 that the difference Δ is ₂ Above the second threshold, it can be determined that the wiring of bin 22 is problematic, i.e., the above-mentioned wiring reversal of the two bins has occurred and the two bins are connectedThe voltage of the bit is exactly the same again. At this point, as shown in block 318, the use of the bin 22 should also be stopped immediately to avoid charging anomalies due to wiring errors. In a further embodiment, such an error condition may also be fed back to the maintainer of the charging device 1 to inform him of the maintenance of the charging device 1.

According to the embodiment of the disclosure, various possible situations are considered in the judgment, so that the determination of the wiring state in a centralized architecture is ensured to be accurate, and the safety of the charging device is guaranteed.

In some embodiments, the first threshold value on which the determination in block 306 depends and the second threshold value on which the determination in block 314 depends may be the same. In other embodiments, the first threshold and the second threshold may not be the same.
