For those of ordinary skill in the art, the specific meanings of the above-mentioned terms in the present invention can be understood in specific situations. The various technical solutions in the following embodiments provided in this application, unless they contradict each other, different technical solutions can be combined with each other, and the technical features therein can be replaced with each other.

Example 1

This embodiment provides a safe charging method, which can be applied to a charging station control system or a charging pile control module, as shown in FIG. 1, which includes the following steps:

S101: Obtain the model of the rechargeable vehicle; the model of the rechargeable vehicle may include such forms as a logistics vehicle with a load of xx tons, a taxi, and a vehicle of XX brand and XX model. In this step, the information input by the staff can be received or the relevant data of the vehicle can be automatically collected for identification.

S102: If the vehicle type matches any of the preset dangerous vehicle types, obtain the charging stop parameter threshold corresponding to the vehicle type and the equipment attributes of the charging piles that charge the charged vehicle; the preset dangerous vehicle types are pre-stored Information, when the vehicle type of the charged vehicle is received, it can be compared with the pre-stored information to determine whether the charged vehicle belongs to a certain dangerous vehicle type.

S103: If the charging parameter of the charged vehicle reaches the stop-charging parameter threshold, send a stop-charging signal corresponding to the device attribute; the stop-charging signal is used to control the charging pile to stop charging the charged vehicle .

Dangerous models are models that may undergo spontaneous combustion during the charging process, which are determined based on historical experience data or the actual production and operating conditions of the model itself. For example, a logistics vehicle with a large load capacity needs to have a very large battery capacity, and a long charging time is required during the charging process. If the battery temperature is too high during such a long time, it will increase the risk of spontaneous combustion. At this time, the possibility of spontaneous combustion can be reduced by limiting the charging time. As another achievable way, the following four methods can be used to determine the preset dangerous vehicle type in the above scheme:

(1) Method one for determining dangerous vehicle types:

Step A: According to historical data, obtain the collection of vehicle types of vehicles that have spontaneous combustion events.

Step B: Use a vehicle type whose proportion exceeds a set threshold in the vehicle type set as the preset dangerous vehicle type.

In a historical period of time (such as half a year, one year, etc.), all relevant data of vehicles that have spontaneous combustion can be determined based on historical data. For example, there are 40 spontaneous combustion incidents of electric vehicles within one year, of which four electric vehicles of a certain model have occurred. Therefore, the probability that this model occupies all spontaneous combustion models is 10%. Through this statistical method, it can be determined that the vehicle with a higher proportion of spontaneous combustion vehicles can be identified as a dangerous vehicle. If the currently charged vehicle is one of them, it needs to be adjusted to implement the stop charging strategy, that is, it is not. A full charge is used as the time to stop charging, and a preset charging parameter threshold that can ensure safety is used as the time to stop charging.

(2) Method two for determining dangerous vehicle types:

S1-1: Acquire a charging state image of a charged vehicle, the charging state image includes a charged vehicle image; the image or video of the charged vehicle can be collected by a monitoring device (such as a camera) set in the charging station, so as to obtain The image of the charging vehicle in the charging state. It is also possible to separately add a camera dedicated to image collection of the charging vehicle status in the charging station, so as to obtain images or videos of the charging vehicle in real time.

S1-2: Determine the model of the charged vehicle according to the charged vehicle image. Through the image processing method, the charged vehicle itself can be extracted from the image, and then the vehicle model can be judged according to the relevant information of the charged vehicle itself, which can specifically include:

Manner 1: Analyze the charged vehicle image to obtain the contour of the charged vehicle; determine the model of the charged vehicle according to the contour of the charged vehicle. According to the outline of the vehicle, it can be determined that the vehicle is an ordinary family car, taxi, logistics vehicle, etc., and at the same time, the volume of the charged vehicle can be estimated, and then it can be judged whether it is a logistics vehicle with an excessive load.

Manner 2: Analyze the charged vehicle image to obtain the license plate number of the charged vehicle; obtain the model of the charged vehicle according to the license plate number. That is, after the license plate number of the charging vehicle is determined, it can query databases such as the traffic control bureau system based on the license plate number to obtain the vehicle type of the charging vehicle, and then determine whether it is a dangerous vehicle type.

(3) Method three for determining dangerous vehicle types:

For some users, it uses the APP installed in the mobile terminal to start the charging operation. This part of the user needs to fill in the registration information during the APP registration process, which can include the vehicle to the model. For this part of the user, the charging process can be directly obtained To the user's registration information, and then extract the car model reserved in the registration information as the car model of the charging vehicle.

(4) Method 4 for determining dangerous vehicle types

In the above scheme, each charging pile in the charging station has its specific device attributes. During the charging process, as long as the charging pile is performing a charging operation, it can obtain some data of the charging vehicle, such as charging time, charging amount, etc., and then charging The data is uploaded to the operator platform of the charging station. Therefore, the charging vehicle is associated with the device attributes of the only charging pile when it is being charged. When the charging vehicle is in the charging process, the charging pile connected to the charging vehicle can be determined by analyzing the charging data or monitoring images, and the device attributes of the charging pile can be obtained. After the device attributes of the charging pile are determined, the charging stop strategy can be controlled for the charging pile. This embodiment provides a way:

In the step of acquiring the charging state image of the charging vehicle, the charging state image further includes a charging pile image; the method further includes the step of: determining the device attribute of the charging pile charged for the charging vehicle according to the charging pile image. That is, the device attributes of the charging pile are obtained directly according to the charging pile image recorded in the collected charging state image of the charging vehicle. For example, the specific position of the charging pile in the charging station can be obtained according to the charging pile image, and the charging pile number can be determined according to the position of the charging pile; or the charging pile number and other data can be directly captured in the charging pile image to obtain the charging pile equipment Attributes.

In the above solution, the charging stop parameter threshold can be determined according to the temperature of the charging position, the humidity of the charging environment, and the battery capacity of the vehicle. Based on this, this embodiment also provides a safe charging method as shown in Fig. 2:

S201: Set a corresponding stop-charging parameter threshold value for each preset dangerous vehicle type, the stop-charging parameter threshold value is obtained based on the temperature and/or the humidity of the charging position where the dangerous vehicle type is preset and the battery capacity of the preset dangerous vehicle type A charging duration threshold or a charging amount threshold, where the charging amount threshold is less than the battery capacity. For a charged vehicle, the main reason that affects its charging safety is the temperature of the battery. In this step, according to the charging position temperature and/or humidity and battery capacity, setting the charging duration threshold and the charging amount threshold can effectively control the battery temperature of the charged vehicle. The specific setting method can be based on the data analysis of the vehicle that spontaneously ignites during charging in the historical data to obtain a reasonable threshold. Different vehicle models and unused battery capacities may be different. The charging duration threshold t _th and the charging amount threshold Q _{th in} this embodiment are obtained in the following manner: if T ≥ _{T G} , and/or H ≤ H _L, then t _th =0 and Q _th =0; if T ₁ ＜T＜T _G , and/or H _L ＜H＜H ₁ then t _th ＝t ₁ , Q _th ＝Q ₁ ; if T≤T ₁ , and/or H≥H ₁ then t _th ＝t ₂ , Q _th = Q ₂ , and t ₂ ＞t ₁ , Q ₂ ＞Q ₁ ; above, T is the temperature of the charging position where the dangerous vehicle is preset, T _G is the upper limit of the temperature of the charging position, and T ₁ is the standard temperature range of the charging position H is the humidity of the charging position, H _L is the lower limit of the humidity of the charging position, H ₁ is the minimum value of the humidity standard range; t ₁ and t ₂ are the charging duration thresholds under the corresponding conditions, and both are less than the stated The preset time required for the dangerous vehicle to be fully charged; Q ₁ and Q ₂ are respectively the charge threshold values under corresponding conditions, and both are less than the power required when the preset dangerous vehicle battery is fully charged. Above, the standard range of charging position is the temperature range that can ensure the safety of electric vehicles during the charging process. For example, it can be selected as 15°C-40°C according to the experience value. The upper threshold of the charging position temperature is the risk of spontaneous combustion. The temperature value can be selected to be about 1.5 times the maximum value in the standard temperature range of the charging position. For example, if the maximum value in the standard temperature range of the charging position is 40°C, the upper limit threshold of the charging position temperature is selected to be about 60°C. The humidity standard range of the charging position is the humidity range under normal conditions, and the lower humidity limit can be selected to be about 1/2 of the minimum value in the humidity standard range. For example, if the humidity standard range is 15%-60%, the lower humidity limit can be Choose 7.5%. The above is only an example, and the specific implementation can be appropriately selected according to the geographic location of the charging station.

S202: Acquire a charging state image of a charging vehicle, where the charging state image includes a charging vehicle image; and determining a model of the charging vehicle according to the charging vehicle image.

S203: The charging state image further includes a charging pile image; the device attribute of the charging pile charged for the charging vehicle is determined according to the charging pile image.

S204: If the vehicle type matches any of the preset dangerous vehicle types, obtain a charging stop parameter threshold value corresponding to the vehicle type.

S205: Determine the charging duration threshold or the charging amount threshold corresponding to the charging vehicle according to the charging position temperature of the charging vehicle and/or the humidity of the charging position where the charging vehicle is located and the battery capacity of the charging vehicle; When the charging duration of the charged vehicle reaches the charging duration threshold or the charging amount of the charged vehicle reaches the charging amount threshold, the charging stop signal is sent. That is, according to the interval division of the charging position temperature and the charging position humidity in step S201, the relevant value collected during the actual charging of the charged vehicle falls into which interval, which kind of threshold value is used as the criterion for judging the stop of charging. For example, if the charging point temperature is 35°C and the humidity is 20%, the corresponding charging time threshold is 4 hours, and the charging amount threshold is 95% of the battery capacity. The charging capacity of the vehicle is limited to 95% of the total capacity. Carrying out the stop charging strategy, or controlling the charging vehicle to stop charging when the charging vehicle has been charged for 4 hours, will not affect the normal operation of the vehicle, and at the same time can further ensure the charging safety of the vehicle. For another example, if the temperature of the charging position has reached 60°C, it may be that the charging vehicle itself has a very high temperature. It can be inferred that the battery temperature is already high. At this time, there is a higher risk of charging. The charging duration threshold is set to 0 and the charging amount threshold is set to 0, that is, the charging operation is not provided for the charging vehicle to ensure the safety of the vehicle.

As another achievable way, some electric vehicles are equipped with a module for measuring battery temperature. When such electric vehicles are being charged, the system can directly request the establishment of a communication connection with the charging vehicle. After the communication connection is successfully established, the system can directly request the establishment of a communication connection with the charging vehicle. The real-time battery temperature data of the charged vehicle can be directly obtained through the vehicle terminal of the charged vehicle. At this time, it can be directly judged according to the real-time battery temperature of the charging vehicle whether it is necessary to stop charging for it. The battery temperature threshold can be selected about 1.2 times the highest value in the battery's normal charging temperature range. For example, the battery's normal temperature range during charging is 20°C-45°C, and the battery temperature threshold can be selected as 54°C. During the charging process of a charged vehicle, the real-time battery temperature can be sent to the operator platform, and the operator platform can control to stop charging the charged vehicle after monitoring the real-time battery temperature value reaches 54°C.

In the above scheme, as shown in Figure 2, the following steps may also be included:

S206: Acquire terminal information associated with the charged vehicle. The terminal information is preferably the phone number or WeChat ID of the passenger or the App account information installed on the mobile phone.

S207: Send a prompt message for limiting the charging time or limiting the charging amount to the terminal device according to the terminal information. That is, if the charging vehicle is a dangerous vehicle type, the passengers will be notified in advance to make them aware that their vehicle will be restricted from charging, so that they have an understanding of the charging time.

Further, the above solution also includes when sending a charge stop signal:

S208: Send a prompt message to stop charging to the terminal device. This solution can inform the charging user in time when the charging of the charging vehicle is stopped in advance, and it is convenient for the user to remove the vehicle in time so that other vehicles can be charged as soon as possible.
