In other embodiments, custom and/or dedicated data communication techniques may also be used in place of, or in addition to, the data communication techniques described above.
Fig. 2 is a flowchart illustrating a method of charging pile status detection according to an example embodiment. The method is performed by a cloud server, which may be the server 110 in the charging pile status detection system as shown in fig. 1. As shown in fig. 2, the charging pile state detection method may include the following steps:
step 201, receiving a first charging record and a second charging record uploaded by a target vehicle.
The first charging record is used for indicating the charging condition of the target vehicle in the first charging pile; the second charging record is used for indicating the charging condition of the target vehicle in the second charging pile.
When a target vehicle is charged in the first charging pile, a BMS system in the target vehicle detects the state of the target vehicle and generates a first charging record; and similarly, when the target vehicle is charged in the second charging pile, the BMS system in the target vehicle detects the state of the target vehicle and generates a second charging record.
Optionally, the first charging record includes an insulation resistance value obtained by insulation detection of the target vehicle by the BMS system in the charging process of the first charging pile. The second charging record contains the insulation resistance value obtained by insulation detection of the target vehicle in the charging process of the second charging pile by the BMS system.
Step 202, determining a first insulation state of the target vehicle when the first charging pile is charged according to the first charging record.
After the server acquires the first charging record, the first insulation state of the target vehicle in the charging process of the first charging pile can be determined according to the insulation resistance value of the target vehicle in the charging process of the first charging pile, which is indicated by the first charging record.
When the first insulation state is the abnormal state, the insulation resistance value of the target vehicle in the charging process of the first charging pile can be considered to be in an unsafe state; and when this first insulation state is normal state, then can think this target vehicle in the charging process of first electric pile, the insulating resistance is in safe state, and the probability that takes place the electric leakage accident is very little.
In one possible implementation manner, when the lowest value of the insulation resistance value of the target vehicle during charging of the first charging pile in the first charging record is smaller than the safety threshold, the first insulation state is determined to be abnormal.
When the lowest value of the insulation resistance value of the target vehicle during charging of the first charging pile is smaller than the safety threshold value in the first charging record, the target vehicle represents that the current flowing through the vehicle body can damage the human body at a certain moment during charging, and the first insulation state of the target vehicle during charging of the first charging pile is determined to be an abnormal state.
Alternatively, in another possible implementation manner, when in the first charging record, the time that the insulation resistance value of the target vehicle is smaller than the safety threshold value when the first charging pile is charged is greater than the time threshold value, the first insulation state is determined as the abnormal state.
When the insulation resistance value of the target vehicle in the first charging record is smaller than the safety threshold value and the time shorter than the safety threshold value is longer than the time threshold value, the insulation resistance value of the target vehicle is not in accordance with the safety regulation in a long time, and the current which can cause damage to a human body may be provided on the vehicle body, so that the first insulation state of the target vehicle in the first charging pile is determined to be an abnormal state.
Step 203, when the first insulation state is abnormal, determining a second insulation state of the target vehicle in the second charging pile according to the second charging record.
Optionally, when the first insulation state is normal, the target vehicle does not have the condition that the insulation resistance is too low in the charging process of the first charging pile, and at this moment, the first charging pile can be considered to be in a normal state.
And when the first insulation state is abnormal, the target vehicle is indicated to have potential safety hazard caused by too low insulation resistance value in the charging process of the first charging pile. In order to eliminate the possibility that the abnormality of the first insulation state is caused by the target vehicle, it is necessary to acquire a second insulation state of the target vehicle when the second charging pile is charged.
And 204, judging the position relationship between the first charging pile and the second charging pile, and determining the state of the first charging pile according to the judgment result and the second insulation state so as to inform each vehicle in the area where the first charging pile is located of the state of the first charging pile.
After the first insulation state of the target vehicle in the first charging pile and the second insulation state of the target vehicle in the second charging pile are obtained, whether the target vehicle is charged in the same charging pile or the same batch of charging piles can be judged according to the position relation between the first charging pile and the second charging pile, and whether the first charging pile is abnormal or not is determined according to the judgment result.
For example, when the positional relationship between the first charging pile and the second charging pile is the same position, it indicates that the first charging pile and the second charging pile are the same charging pile or the same batch of charging piles, and at this time, when both the first insulation state of the target vehicle during charging in the first charging pile and the second insulation state of the target vehicle during charging in the second charging pile are abnormal states, it indicates that both the first charging pile and the second charging pile may have problems.
For another example, when the position relationship between the first charging pile and the second charging pile is different, it indicates that the first charging pile and the second charging pile are not the same charging pile or the same batch of charging piles, and at this time, when the first insulation state of the target vehicle when the first charging pile is charging is abnormal, and the second insulation state of the target vehicle when the second charging pile is charging is normal, it is obvious that the first charging pile is abnormal.
For another example, when the position relationship between the first charging pile and the second charging pile is different, when the first insulation state of the target vehicle during charging of the first charging pile is abnormal and the second insulation state of the target vehicle during charging of the second charging pile is also abnormal, it may be that the target vehicle is connected to the charging pile, the insulation resistance value is decreased due to other reasons, that is, the target vehicle itself has a problem, the probability that both the first charging pile and the second charging pile are abnormal is small, and the first charging pile and the second charging pile are not determined to be abnormal temporarily.
In summary, when the target vehicle is charged in the first charging pile and the second charging pile, the first charging record and the second charging record may be generated and uploaded to the cloud server, and the cloud server may analyze the first charging record and the second charging record, thereby obtaining whether the first insulation state of the target vehicle in the charging process of the first charging pile is abnormal or not, when the first insulation state is abnormal, whether the insulation state of the target vehicle is abnormal in the charging process of the second charging pile is judged, thereby accurately judging whether the charging state is the state of the first charging pile or not through two different charging records, informing each vehicle in the area where the first charging pile is positioned, therefore, each vehicle can know the safety state of each charging pile more conveniently and quickly, and potential safety hazards of the electric vehicle when charging caused by abnormal insulation state of the charging pile are reduced as much as possible.
Fig. 3 is a flowchart illustrating a method of charging pile status detection, according to an example embodiment. The method is performed by a cloud server, which may be the server 110 in the charging pile status detection system as shown in fig. 1. As shown in fig. 3, the charging pile status detection method may include the following steps:
step 301, receiving a first charging record and a second charging record uploaded by a target vehicle.
Alternatively, the first charging record and the second charging record uploaded by the target vehicle may be two charging records of the target vehicle within a specified time, such as any two charging records within a week.
When the time difference between the first charging record and the second charging record is large, the timeliness of at least one of the first charging record and the second charging record is poor, for example, the first charging record is generated by the target vehicle during charging of the first charging pile one week ago, and at this time, the first charging record obviously cannot indicate the charging condition of the current first charging pile.
Optionally, the timestamp of the first charging record precedes the second charging record. The first charging record comprises the charging time of the target vehicle in the first charging pile; the second charging record also includes the charging time of the target vehicle in the second charging pile.
Optionally, the first charge record and the second charge record are two consecutive charge records of the target vehicle.
When the first charging record and the second charging record are two continuous charging records of the target vehicle, the first charging record and the second charging record can represent two charging processes of the target vehicle which are separated from each other most recently, so that the charging state of the first charging pile can be compared with the charging state of the second charging pile under the condition that the state of the target vehicle is guaranteed to be unchanged as far as possible.
Step 302, determining a first insulation state of the target vehicle when the first charging pile is charged according to the first charging record.
In a possible implementation manner, the first charging record includes the insulation resistance value change condition of the target vehicle when the first charging pile is charged; dividing the first charging record into charging intervals with target quantity, and calculating a first average insulation resistance value of each charging interval; performing linear fitting on the first average insulation resistance value of each charging interval to obtain a first fitting curve; and when the slope of the first fitted curve is smaller than 0 and the ratio of the minimum value to the maximum value in the first average insulation resistance value is smaller than a proportional threshold, determining that the first insulation state of the target vehicle during charging of the first charging pile is an abnormal state.
When the target vehicle is charged by the first charging pile, the BMS system in the target vehicle may detect the insulation resistance of the target vehicle at regular intervals (e.g., once every ten seconds), so that the first charging record includes the change of the insulation resistance of the target vehicle when the first charging pile is charged.
The first charging record may be divided into a target number of charging intervals by charging time at this time, and for example, when the first charging record indicates data generated by the target vehicle during a charging process within two hours, the server may divide the charging process within two hours into 12 ten-minute charging intervals. And for each charging interval, the server carries out average processing on the insulation resistance values detected in the charging interval to obtain a first average insulation resistance value corresponding to each charging interval. At this time, the first average insulation resistance value represents the overall condition of the insulation resistance value in the charging interval.
After the first average insulation resistance values corresponding to the charging intervals are obtained, linear fitting can be performed on the first average insulation resistance values of the charging intervals according to a time sequence to obtain a first fitting curve, and the first fitting curve can represent the change situation of the insulation resistance values of the target vehicle in the charging process indicated by the first charging record.
When the slope of the first fitting curve is smaller than 0, it is indicated that the insulation resistance value of the target vehicle is in a descending state in the whole charging process, the insulation resistance value of the target vehicle is obviously affected by the first charging pile, and the insulation resistance value gradually descends, so that the risk of electric leakage is caused.
And when the ratio of the minimum value to the maximum value in the first average insulation resistance value is smaller than the proportional threshold, the insulation resistance value of the target vehicle is shown, the reduction condition in the whole charging process exceeds an acceptable range, the insulation resistance value of the target vehicle is excessively reduced, obviously, the state of the target vehicle in the first charging pile during charging is abnormal, the electric leakage risk is large, and therefore the first insulation state of the target vehicle in the first charging pile during charging is an abnormal state.
In another possible implementation manner, when the slope of the first fitted curve is smaller than 0, and the difference between the minimum value and the maximum value in the first average insulation resistance value is larger than a drop threshold, it is determined that the first insulation state of the target vehicle when the first charging pile is charged is an abnormal state.
When the difference value between the minimum value and the maximum value in the first average insulation resistance value is larger than the drop threshold value, the insulation resistance value of the target vehicle is also shown, the drop condition in the whole charging process exceeds an acceptable range, the insulation resistance value of the target vehicle drops excessively, obviously, the state of the target vehicle during charging of the first charging pile is abnormal, the electric leakage risk is large, and therefore the first insulation state of the target vehicle during charging of the first charging pile is an abnormal state.
Step 303, when the first insulation state is abnormal, determining a second insulation state of the target vehicle in the second charging pile according to the second charging record.
In a possible implementation manner, the second charging record includes the insulation resistance value change condition of the target vehicle when the second charging pile is charged; dividing the second charging record into charging intervals with target quantity, and calculating a second average insulation resistance value of each charging interval; and performing linear fitting on the second average insulation resistance value of each charging interval to obtain a second fitting curve.
And when the slope of the second fitted curve is smaller than 0 and the ratio of the minimum value to the maximum value in the second average insulation resistance values is smaller than a proportional threshold, determining that the second insulation state of the target vehicle is an abnormal state when the second charging pile is charged.
And when the slope of the second fitted curve is greater than 0, determining that the second insulation state of the target vehicle in the second charging pile is a normal state.
And when the slope of the second fitted curve is smaller than 0 and the ratio of the minimum value to the maximum value in the second average insulation resistance values is larger than a proportional threshold, determining that the second insulation state of the target vehicle is a normal state when the second charging pile is charged.
Similarly, the second charging record may be divided into a target number of charging intervals according to the charging time, for example, when the second charging record indicates data generated by the target vehicle during the charging process within two hours, the server may divide the charging process within two hours into 12 ten-minute charging intervals. And for each charging interval, the server carries out average processing on the insulation resistance values detected in the charging interval to obtain second average insulation resistance values corresponding to the charging intervals. At this time, the second average insulation resistance value represents the overall condition of the insulation resistance value in the charging interval.
After the second average insulation resistance values corresponding to the charging intervals are obtained, linear fitting can be performed on the second average insulation resistance values of the charging intervals according to a time sequence to obtain a second fitting curve, and the second fitting curve can represent the change situation of the insulation resistance values of the target vehicle in the charging process indicated by the second charging record.
When the slope of the second fitting curve is smaller than 0, it is indicated that the insulation resistance value of the target vehicle is in a descending state in the whole charging process, the insulation resistance value of the target vehicle is obviously affected by the second charging pile, the insulation resistance value is gradually reduced, and the electric leakage risk is caused.
And when the ratio of the minimum value to the maximum value in the second average insulation resistance value is smaller than the proportional threshold, the insulation resistance value of the target vehicle is shown, the reduction condition in the whole charging process exceeds an acceptable range, the insulation resistance value of the target vehicle is excessively reduced, obviously, the state of the target vehicle in the second charging pile is abnormal, the electric leakage risk is large, and therefore the second insulation state of the target vehicle in the second charging pile is in an abnormal state.
When the slope of the second fitted curve is greater than or equal to 0, it is indicated that the insulation resistance value of the target vehicle is in a rising state in the whole charging process, and the insulation resistance value of the target vehicle does not have a decreasing trend in the charging process, so that the target vehicle does not have a leakage risk temporarily in the second charging process.
When the slope of the second fitted curve is smaller than 0 and the ratio of the minimum value to the maximum value in the second average insulation resistance values is larger than the proportional threshold, it is indicated that although the resistance value of the target vehicle decreases in the charging process, the decrease trend can be within an acceptable range, and there is no leakage risk temporarily, so that the server can determine the second insulation state of the target vehicle in the charging process of the second charging pile as a normal state.
Optionally, the criterion for determining that the first insulation state is in the normal state is similar to the criterion for determining that the second insulation state is in the normal state, and details are not repeated here. And when the server judges that the first insulation state corresponding to the first charging record is the normal state through the first charging record, the first charging pile can be directly determined to be the normal state or the safe state, and the second charging record is not needed to be used for judging again.
Step 304, when the insulation resistance of the target vehicle after the first charging pile is charged is larger than the safety threshold, judging the position relationship between the first charging pile and the second charging pile according to the position information recorded in the first charging record and the position information recorded in the second charging record.
When the insulation resistance value of the target vehicle after the first charging pile is charged is larger than the safety threshold value, it is indicated that the insulation resistance value of the target vehicle is abnormal in the charging process of the first charging pile, and after the charging of the first charging pile is completed, the insulation resistance value of the target vehicle is not abnormal, so that the condition that the insulation resistance value is too low due to the self problem of the target vehicle is eliminated.
And the server can further confirm whether the insulation resistance of the target vehicle is too low due to the first charging pile according to a second charging record of the target vehicle in the second charging pile. Before judging the state of the first charging pile according to the second insulation state in the second charging pile, the server also needs to judge the position relationship between the first charging pile and the second charging pile. Optionally, the location information may be location information acquired by the target vehicle through a navigation system (such as a GPS) during the charging process of the first charging pile and the charging process of the second charging pile, respectively.
When the geographic positions of the first charging pile and the second charging pile are the same, the fact that the first charging pile and the second charging pile belong to the same batch of charging piles is indicated, and the positions of the first charging pile and the second charging pile can be considered to be the same. And when the address positions of the first charging pile and the second charging pile are different, the positions of the first charging pile and the second charging pile are different.
And 305, determining the state of the first charging pile according to the judgment result and the second insulation state so as to inform each vehicle in the area where the first charging pile is located of the state of the first charging pile.
In a possible implementation manner, when the position information of the first charging pile is the same as that of the second charging pile and the second insulation state is an abnormal state, the first charging pile and the second charging pile are determined to be in the abnormal state.
When the position information of the first charging pile is the same as that of the second charging pile, the second insulation state is also an abnormal state, the first insulation state and the second insulation state are both abnormal states at the moment, namely, the charging piles of the target vehicle at the same position have the two-time insulation abnormality, and the server directly determines the first charging pile and the second charging pile to be the abnormal states at the moment.
Optionally, because the position information of the first charging pile is the same as that of the second charging pile, the server may obtain target position information where the first charging pile and the second charging pile are located, and determine the charging pile on the target position information as an abnormal state, thereby determining the first charging pile and the second charging pile as the abnormal state.
In an actual application environment, charging piles in the same geographic position are usually installed and deployed in the same batch, specifications of the charging piles are greatly identical, when more than two insulation abnormal events occur in the charging pile in a certain geographic position, the server can directly determine the charging pile in the geographic position as an abnormal charging pile and send a notification to each vehicle in the area where the first charging pile is located, and therefore safety accidents are avoided as far as possible.
In another possible implementation manner, when the position information of the first charging pile is different from that of the second charging pile, and the second insulation state is a normal state, the first charging pile is determined to be in an abnormal state.
When the position information of the first charging pile is different from that of the second charging pile, and the second insulation state is a normal state, the insulation state of the target vehicle is an abnormal state when the first charging pile is charged, and the insulation state of the target vehicle when the second charging pile is charged is a normal state, which indicates that the insulation state of the target vehicle when the first charging pile is charged is not caused by the target vehicle, and more probably caused by the first charging pile, so that the server determines the first charging pile to be an abnormal state.
In one possible implementation manner, when the first charging pile is determined to be in an abnormal state, an abnormal prompt is sent to each vehicle in the area where the first charging pile is located; the abnormity prompt is used for indicating that the area where the first charging pile is located has charging abnormity.
In summary, when the target vehicle is charged in the first charging pile and the second charging pile, the first charging record and the second charging record may be generated and uploaded to the cloud server, and the cloud server may analyze the first charging record and the second charging record, thereby obtaining whether the first insulation state of the target vehicle in the charging process of the first charging pile is abnormal or not, when the first insulation state is abnormal, whether the insulation state of the target vehicle is abnormal in the charging process of the second charging pile is judged, thereby accurately judging whether the charging state is the state of the first charging pile or not through two different charging records, informing each vehicle in the area where the first charging pile is positioned, therefore, each vehicle can know the safety state of each charging pile more conveniently and quickly, and potential safety hazards of the electric vehicle when charging caused by abnormal insulation state of the charging pile are reduced as much as possible.

2) the cloud background reads the insulation resistance value of the whole vehicle running data after the vehicle is charged at this time, and if the insulation resistance value is larger than the whole vehicle insulation resistance value low threshold value in the whole vehicle running process, the next step is carried out;
3) the cloud background reads the insulation resistance value data of the vehicle during next gun insertion charging, and if the following conditions are met, it is judged that the charging pile is abnormal:
a) the insulation resistance value is abnormal again during the gun insertion charging period of the vehicle, and the geographic position is the same as the previous time;
b) the insulation resistance value is normal during the charging period of the vehicle gun insertion and the geographic position is different from the previous time;
4) and when the charging pile is judged to be abnormal, early warning is carried out on users in the area, the charging pile is informed of the abnormality, and the abnormality mark is cancelled after the charging pile is repaired.
