Background

Conventional fuel vehicles are increasingly replaced by electric vehicles for environmental reasons. The electric vehicle needs a charging pile to be charged. There are currently many charging stake enterprises that own their respective charging stake. But this is often inconvenient for the user, because the user can typically only see the charging piles of one charging pile enterprise through the application of that charging pile enterprise, but the number of charging piles of one charging pile enterprise is limited and the nearest charging piles may be far from the current location of the user.

In this regard, the charging pile aggregation platform gradually becomes a development trend. Fill electric pile polymerization platform and get up the electric pile that fills of different electric pile enterprises to the user can select to use the electric pile that fills with its current position distance nearest from different electric pile enterprises through a platform.

In order to monitor the charging post, the charging post company communicates with its charging post under its flag via a network, in particular a wireless network. The charging pile aggregation platform is generally only in communication with a charging pile enterprise, and obtains charging pile information from the charging pile enterprise. The communication protocols and software designs of different charging pile enterprises are generally different from each other, so that the charging pile aggregation platform generally does not directly manage charging piles, but rather generally manages respective charging piles by the charging pile enterprises themselves. But this is obviously inconvenient for charging pile aggregation platforms.

The principles, features and advantages of the present application may be better understood by describing the present application in more detail with reference to the drawings. The drawings include:

fig. 1 shows an example of a charging pile system of the present application.

Fig. 2 schematically shows an example of the method for troubleshooting an abnormal charging pile of the present application in a flow chart.

Detailed Description

In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the application.

Fig. 1 shows an example of a charging pile system of the present application. The charging pile system comprises a charging pile management system and a plurality of charging piles 3 managed by the charging pile management system. The charging stake 3 is used to charge the vehicle 4.

In fig. 1, the charging pile management system is exemplarily a charging pile aggregation platform 1. The charging piles 3 managed by the charging pile aggregation platform 1 may be charging piles 3 from different charging pile enterprises 2. Three different charging piles 3 (i.e., a first charging pile 31, a second charging pile 32, and a third charging pile 33) from three charging pile enterprises 2 (i.e., a first charging pile enterprise 21, a second charging pile enterprise 22, and a third charging pile enterprise 23) are exemplarily shown in fig. 1. The enterprise system of the charging pile enterprise 2 communicates with its charging piles 3 under its flag via a network, in particular a wireless network, to monitor the charging piles 3. The charging pile aggregation platform 1 then typically communicates only with the enterprise system of the charging pile enterprise 2, and only obtains the information of the charging piles 3 from the enterprise system of the charging pile enterprise 2. The communication protocols and software designs of the different charging pile enterprises 2 are generally different from each other, so that the charging pile aggregation platform 1 generally does not directly manage the charging piles 2, but generally manages the respective charging piles 2 by the charging pile enterprises 2 themselves. But this is obviously inconvenient for the charging pile aggregation platform 1.

In this regard, the present application proposes a method for troubleshooting an abnormal charging pile. It can help the charging pile aggregation platform 1 to monitor the charging piles 3 from the platform level based on the charging pile information obtained from the charging pile enterprise 2 without additional modification, in particular, to find abnormal charging piles.

As shown in fig. 2, the method includes an inspection process 6, where the inspection process 6 includes the following steps:

an acquisition step 60 of acquiring information of a charging interface state of the charging pile 3 during at least one charging task of the charging pile 3 in the acquisition step 60;

and a checking step 61, in the checking step 61, checking whether the jump sequence of the charging interface state of the charging pile 3 accords with the specific jump sequence or not according to the at least one charging task, if so, determining that the charging pile 3 is normal, and if not, determining that the charging pile 3 is an abnormal charging pile.

Based on the above method, the abnormal charging pile can be inspected in a very simple manner.

A charging task is in particular to withdraw the charging gun from the charging post 3 at least until the charging gun is inserted back into the charging post 3 after the charging is completed. A charging task is also understood to mean, in particular, a charging order, i.e. at least from the time a charging request is issued until the charging is completed and the electric vehicle is disconnected from the charging post 3.

According to an exemplary embodiment, the charging interface states include at least A, B, C states, a representing that the charging interface of the charging post 3 is idle, B representing that the charging interface of the charging post 3 is occupied but not charging, C representing that the charging interface of the charging post 3 is occupied and charging. It is also contemplated that the charging interface states include only two states, a and C, or more.

According to an exemplary embodiment, the specific hopping sequence includes four of:

A-B-C-B-A；

A-B-C-A；

A-C-B-A; and

A-C-A。

in the checking step 61, if the hopping sequence of the charging interface states of the charging piles 3 does not conform to any of these four specific hopping sequences, the charging piles 3 are regarded as abnormal charging piles.

The following is additionally considered here: after the charging gun is inserted into the vehicle, the user may not directly start charging due to the desire to smoke or call, but start charging after doing the miscellaneous matters, wherein the jump sequence of the charging interface state is A-B-C-A or A-B-C-B-A; or, similarly, after the charging is completed, the user may not end the charging directly, but rather end the charging with ase:Sub>A slight delay, where the jump sequence of the charging interface states is ase:Sub>A-C-B-ase:Sub>A or ase:Sub>A-B-C-B-ase:Sub>A.

According to an exemplary embodiment, referring to fig. 1 and 2, in an acquiring step 60, the charging pile aggregation platform 1 acquires information of the charging piles 3 via an enterprise system of the charging pile enterprise 2 responsible for the charging piles 3; in the checking step 61, the charging pile aggregation platform 1 checks the hopping sequence of the charging interface states of the charging piles 3. Through the mode, the charging pile aggregation platform 1 can uniformly and reliably check the abnormal charging piles on the platform level simply and reliably based on the information obtained from the charging pile enterprises 2.

According to an exemplary embodiment, in an investigation step 61, it is investigated whether the duration of the charging interface state C exceeds a charging duration threshold and/or whether the duration of time taken for completing each charging task exceeds a task duration threshold. The charge duration threshold or task duration threshold may be set to 12 hours, for example. If the charge duration threshold and/or the task duration threshold is exceeded in one charge task, the charge stake 3 may be identified as an abnormal charge stake. It is also contemplated that if more than three times a week exceed the charge duration threshold and/or the task duration threshold, an abnormal charge stake is deemed to be abnormal.

According to an exemplary embodiment, as shown in fig. 2, the investigation flow 6 includes an abnormal number monitoring step 62, in which if the charge pile 3 is recognized as an abnormal charge pile twice in succession in two investigation flow 6 performed for the current charge task and the previous charge task and/or if the number of times the charge pile 3 is recognized as an abnormal charge pile exceeds a predetermined number in a plurality of investigation flow 6 performed for a plurality of charge tasks up to the current charge task, the charge pile 3 is recognized as abnormal. By performing the deep investigation with at least two charging tasks, maintenance costs can be appropriately reduced while ensuring the investigation accuracy. For the case of a plurality of charging tasks, it is exemplarily conceivable that, in the case of five charging tasks in succession, if the charging pile 3 is identified as an abnormal charging pile by the checking flow 6 in the first, third and fifth charging tasks, it can also be identified accordingly that the charging pile 3 is abnormal. Obviously, other suitable settings for monitoring the number of anomalies are also conceivable.

According to one exemplary embodiment, as shown in fig. 2, the method includes a process flow 7, the process flow 7 being performed for an abnormal charging pile.

According to an exemplary embodiment, as shown in fig. 2, the process flow 7 includes a restarting step 71, in which the charging pile 3 is restarted. The presence of an abnormality in a charging pile 3 in a charging task does not absolutely mean that the charging pile 3 is indeed abnormal. An exception, for example due to software reasons, may be recovered by restarting the exception charging stake. It is further conceivable that, as shown in fig. 2, the restarting step 71 is performed for the charging pile 3 which is not determined to be abnormal in the abnormal number monitoring step 62.

According to an exemplary embodiment, as shown in fig. 2, process flow 7 includes a process step 72, where a signal of an abnormality of charging stake 3 is output and/or charging stake 3 is turned off and/or charging stake 3 is made user-selectable on the application program in process step 72.

Outputting a signal that the charging stake 3 is abnormal may include outputting to a user through the charging stake 3, outputting to a platform manager at the charging stake management system, and outputting to a user through an associated mobile device, such as a cell phone. Obviously, the output is mainly a visual output, but alternatively or additionally an audible output and/or a tactile output may be envisaged.

Charging is currently being requested and paid more and more through apps on mobile phones, and abnormal charging piles can be conveniently avoided from being used by users by making the abnormal charging piles non-selectable for users on application programs.

It is conceivable that the processing step 72 is performed directly for the charging pile 3 identified as the abnormal charging pile, or, as shown in fig. 2, the processing step 72 is performed on the charging pile 3 after it is identified that it is abnormal. It is exemplarily conceivable to classify and handle abnormal charging piles according to the frequency of use of the charging piles 3. For example, for a charging pile 3 used at a high frequency, the charging pile 3 identified as an abnormal charging pile may be directly shut down so as to prevent a plurality of subsequent users from using the charging pile 3 and to inform the charging pile management system to perform maintenance as soon as possible, while for a charging pile 3 used at a low frequency, the charging pile 3 may be shut down after the identification of the abnormal charging pile is confirmed.

According to an exemplary embodiment, as shown in fig. 2, the method comprises a self-test monitoring procedure 5, in which self-test monitoring procedure 5 the self-test condition of the charging pile 3 is monitored at least prior to the charging task. Thereby, charging piles which cannot even enter a charging task are eliminated in advance.

According to an exemplary embodiment, as shown in fig. 2, the self-test monitoring process 5 includes a self-test monitoring step 50, in which whether the charging pile 3 is self-tested for a fault state and/or an off-grid state is monitored, and if so, the charging pile 3 is identified as an abnormal charging pile. A restart step 71 or a process step 72 may be performed for the abnormal charge pile. It is also conceivable that in the self-test monitoring step 50, the duration of the fault state and/or off-grid state is additionally taken into account when identifying an abnormal charging pile. If the charging pile 3 is restored after a short self-test to a faulty state or an off-grid state, the charging pile 3 will still be considered normal.

According to an exemplary embodiment, as shown in fig. 2, the self-checking monitoring process 5 includes a restart number monitoring step 51, and if the self-checking monitoring step 50 results in yes, the restart number monitoring step 51 is performed, and in the restart number monitoring step 51, if it is monitored that the restart number of the charging pile 3 exceeds the preset number, it is determined that the charging pile 3 is abnormal. It is conceivable that, as shown in fig. 2, the processing step 72 is performed for the charging pile 3 determined to be abnormal by the restart number monitoring step 51, and the restarting step 71 is performed for the charging pile 3 not determined to be abnormal in the restart number monitoring step 51.

In the above description, the method of the present application is described primarily with respect to a charging pile aggregation platform. But alternatively also conceivable: the method of the application is implemented directly by the charging pile or by the charging pile management system of the charging pile enterprise itself. For example, during each charging task, the acquiring step and the checking step are performed on the charging pile, the charging pile feeds back the checking result to the charging pile management system of the charging pile enterprise after the checking is completed, or the charging pile transmits the charging interface state to the charging pile management system of the charging pile enterprise through the network, and the charging pile management system of the charging pile enterprise performs the checking step after acquiring the information of the charging interface state of the charging pile.

Some of the benefits are described in the specification. It is noted that these benefits should not be construed as mandatory, but may only be achieved in certain application scenarios.

Although specific embodiments of the application have been described in detail herein, they are presented for purposes of illustration only and are not to be construed as limiting the scope of the application. Various substitutions, alterations, and modifications can be made without departing from the spirit and scope of the application.
