< method example >
Fig. 2 is a flowchart of a method for determining a failure of an electric vehicle according to an embodiment of the present invention.
The method may be implemented by a server, which may be in various physical forms. For example, the server may be a cloud server, or may also be a server 1000 as shown in fig. 1.
As shown in fig. 2, the method of the present embodiment may include the steps of:
step 4100, calculating a time difference between a current time point and a time point when the electric vehicle changes the battery when the state report information from the electric vehicle is not received at a preset time interval.
The state report information is used for informing a server of the current use state of the electric vehicle. For example, the status report information may include at least: the identification information of the electric vehicle, GPS position information, battery power and firmware version information.
The identification information of the electric vehicle is used for uniquely identifying the electric vehicle, and for example, the identification information can be the number of the electric vehicle. And the GPS position information of the electric vehicle is used for identifying the current geographic position of the electric vehicle. The battery power is used for indicating the current power of the battery of the electric vehicle so that an operator can judge whether the battery needs to be replaced or not. The firmware version information of the electric vehicle may be, for example, information such as a bluetooth version used by the electric vehicle.
The preset time interval is preset. For example, if the preset time interval is half an hour, the electric vehicle sends the current status report information to the server every half an hour. If the preset time interval is 1 hour, the electric vehicle sends current state report information to the server once every 1 hour.
Specifically, a server receives the status report information from the electric vehicle; and recording the time point when the status report information is received. After receiving the status report information from the electric vehicle, the server starts a timer corresponding to the electric vehicle, and judges whether new status report information from the electric vehicle is received or not when the timer finishes counting.
And the timing duration of the timer is equal to the preset time interval. For example, if the preset time interval is 1 hour, the timing duration of the timer is 1 hour correspondingly.
When the timer is finished, the server receives new state report information from the electric vehicle under the condition that the electric vehicle has no fault, records the time point of receiving the state report information, and starts a new timer.
When the battery level in the status report information is full, the time point when the status report information is received is recorded as the time point when the battery of the electric vehicle is replaced.
When the timer is finished and the electric vehicle fails, the server does not receive the state report information from the electric vehicle. That is, if status report information of the electric vehicle is not received at a preset time interval, it is indicated that the electric vehicle currently has a fault. At this time, the server needs to calculate a time difference between the current time point and the time point of battery replacement of the electric vehicle, so as to determine a specific fault type of the electric vehicle according to the time difference.
After the time difference is calculated, step 4200 is performed to determine whether the time difference is greater than a preset battery power usage time threshold of the electric vehicle.
The battery power use time threshold is set according to the longest battery power use time. And the longest service time of the battery, after a great amount of test is carried out on the service time length of the battery of the electric vehicle, the obtained battery can normally support the duration of the electric vehicle for sending the state report information.
Specifically, the battery power usage time threshold may be set to be 70% or 80% or 90% of the maximum battery power usage time. The present embodiment is not particularly limited thereto.
For example, if the test shows that the maximum service life of the battery is 100 hours, the set battery power service life threshold is 80% of the maximum service life of the battery. Correspondingly, the preset battery power use time threshold in the step is 80 hours. If the set battery power usage time threshold is 90% of the longest battery power usage time, the battery power usage time threshold preset in the step is 90 hours.
Step 4300, marking the fault type of the electric vehicle according to the judgment result.
Wherein, the judging result comprises: the time difference is greater than the battery power usage time threshold, or the time difference is less than or equal to the battery power usage time threshold.
In the step, if the time difference is greater than the battery power use time threshold, marking the fault type of the electric vehicle as a low power fault; and if the time difference value is smaller than or equal to the battery electric quantity using time threshold value, marking the fault type of the electric vehicle as the fault of the GPS module of the electric vehicle.
For example, if the battery power usage time threshold is 80 hours, the calculated time difference between the current time point and the time point of battery replacement of the electric vehicle is 90 hours, and if the calculated time difference is greater than the battery power usage time threshold for 80 hours, it indicates that the battery power consumption of the electric vehicle is relatively high, and the electric vehicle is not supported to send status report information to the server at preset time intervals. Therefore, the server marks the fault type of the electric vehicle as a low battery fault.
If the use time threshold of the battery power is 80 hours, the calculated time difference between the current time point and the time point of battery replacement of the electric vehicle is 60 hours, and is smaller than the use time threshold of the battery power for 80 hours, the fault of the GPS module of the electric vehicle is indicated, and the state report information cannot be sent to the server at preset time intervals. Accordingly, the server marks the fault type of the electric vehicle as a GPS module fault.
After the fault classification of the electric vehicle is marked in the server, operators can conduct targeted fault intervention according to different fault types. For example, for a low battery fault, an operator may concentrate on replacing a battery or charging a battery of an electric vehicle marked as a low battery fault within a certain zone. For a GPS module failure, operators can repair the electric vehicles in their jurisdictions marked as a GPS module failure.
The determination method of the electric vehicle failure provided in the present embodiment has been described above with reference to the accompanying drawings. According to the method for determining the faults of the electric vehicle, when the state report information from the electric vehicle is not received at the preset time interval, the time difference value between the current time point and the time point of battery replacement of the electric vehicle is calculated; judging whether the time difference value is larger than a preset battery electric quantity service time threshold value of the electric vehicle; and marking the fault type of the electric vehicle according to the judging result. Through the fault classification mark to the electric motor car for the operator can provide the operation and maintenance service of pertinence according to different fault types, thereby can save operation human cost, improve operation and maintenance service's quality and efficiency.
