Translated fromChinese技术领域technical field
本发明涉及电动车辆充电技术领域，具体涉及一种安全充电方法、存储介质及系统。The invention relates to the technical field of electric vehicle charging, in particular to a safe charging method, a storage medium and a system.
背景技术Background technique
电动车辆在充电过程中，充电桩会与电动车辆进行通信，判断电动车辆类型或者车辆电池类型，然后根据车辆电池的需求进行充电。在正常情况下，如用户没有主动停止充电或者电动车辆、充电桩未发生故障(例如温度过高、车桩通信故障)的情况下，充电桩会一直为电动车辆充电直至车辆电池充满。由于电动车辆的充电时间较长，一般情况下在车辆充电过程中车主会离开充电车辆，导致充电车辆处于无人监察的情况。但是，某些车辆发生自燃恰恰是发生在充电期间，这些自燃事件发生时均处于正常充电状态。在充电期间车辆自燃给充电站内及周围带来极大的安全隐患。因此，如何避免电动车辆在充电过程中发生自燃成为亟待解决的问题。During the charging process of the electric vehicle, the charging pile will communicate with the electric vehicle, determine the type of the electric vehicle or the battery type of the vehicle, and then charge according to the needs of the vehicle battery. Under normal circumstances, if the user does not actively stop charging or the electric vehicle and the charging pile are not faulty (for example, the temperature is too high, the vehicle pile communication failure), the charging pile will continue to charge the electric vehicle until the vehicle battery is fully charged. Due to the long charging time of an electric vehicle, in general, the vehicle owner will leave the charging vehicle during the charging process, resulting in the charging vehicle being left unsupervised. However, the spontaneous combustion of some vehicles occurs precisely during the charging period, and these spontaneous combustion events are all in a normal charging state. Vehicle spontaneous combustion during charging brings great safety hazards in and around the charging station. Therefore, how to avoid spontaneous combustion of electric vehicles during the charging process has become an urgent problem to be solved.

The various technical solutions in the following embodiments provided in this application, unless they contradict each other, the different technical solutions can be combined with each other, and the technical features therein can be replaced with each other.
实施例1Example 1
本实施例提供一种安全充电方法，可应用于充电站控制系统或充电桩控制模块中，如图1所示，其包括如下步骤：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：获取充电车辆的车型；充电车辆的车型可以包括如载重xx吨的物流车、出租车、XX品牌XX型号车等形式。本步骤可以接收工作人员输入的信息或者通过自动采集车辆的相关数据来识别得到。S101: Obtain the model of the charging vehicle; the model of the charging vehicle may include, for example, 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 identification can be obtained by automatically collecting relevant data of the vehicle.
S102：若所述车型与任一预设危险车型匹配，则获取与所述车型对应的停充参数阈值，以及为所述充电车辆充电的充电桩的设备属性；预设危险车型为预存储的信息，当接收到充电车辆的车型后，与预存储的信息进行比对即可判定充电车辆是否属于某一种危险车型。S102: If the vehicle type matches any of the preset dangerous vehicle types, obtain a charging stop parameter threshold corresponding to the vehicle type, and the device attributes of the charging pile charging the charging vehicle; the preset dangerous vehicle type is a pre-stored vehicle type. After receiving the vehicle type of the charging vehicle, it can be compared with the pre-stored information to determine whether the charging vehicle belongs to a certain dangerous vehicle type.
S103：若所述充电车辆的充电参数达到所述停充参数阈值，则发送与所述设备属性对应的停充信号；所述停充信号用于控制所述充电桩停止为所述充电车辆充电。S103: If the charging parameter of the charging vehicle reaches the charging stop parameter threshold, send a charging stop signal corresponding to the device attribute; the charging stop signal is used to control the charging pile to stop charging the charging vehicle .
危险车型是根据历史经验数据或者根据车型本身的实际生产情况及运行情况确定的在充电过程中可能会发生自燃现象的车型。例如，载重量较大的物流车辆，其本身的电池容量需要非常大，在充电过程中需要很长的充电时长，在如此长的时间内电池的温度如果过高则会增加自燃的风险。此时，可以通过限定其充电时长的方式来降低其发生自燃的可能性。作为另一种可实现的方式，以上方案中可以通过如下四种方法确定预设危险车型：Dangerous vehicles are vehicles that may spontaneously ignite during the charging process, as determined based on historical experience data or the actual production and operating conditions of the vehicle itself. For example, for a logistics vehicle with a large load, its own battery capacity needs to be very large, and it requires a long charging time during the charging process. If the temperature of the battery is too high during such a long period of 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, in the above solution, the following four methods can be used to determine the preset dangerous vehicle type:
(1)用于确定危险车型的方法一：(1) Method 1 for determining dangerous vehicles:
步骤A：根据历史数据得到发生自燃事件车辆的车型集合。Step A: According to the historical data, the model set of the vehicle with the spontaneous combustion event is obtained.
步骤B：以所述车型集合中占比超过设定阈值的车型作为所述预设危险车型。Step B: Taking the vehicle type whose proportion exceeds the set threshold in the vehicle type set as the preset dangerous vehicle type.
在一段历史时间内(如半年、一年等)根据历史数据能够确定发生自燃的车辆的所有相关数据，例如一年以内共发生40次电动汽车自燃事件，其中某车型电动汽车发生了4次，则该车型占所有发生自燃车型中的概率为10％。通过这种统计方式，能够确定出自燃车辆中占比重较高的车型，其可以被认定为危险车型，如果当前充电车辆为其中一种，则需要对其进行执行停充策略的调整，即不以充满电为停充时机，而以预先设定的能确保安全的充电参数阈值为停充时机。During a period of history (such as half a year, one year, etc.), all relevant data of vehicles that have spontaneous combustion can be determined according to historical data. For example, a total of 40 spontaneous combustion events of electric vehicles have occurred within one year, of which 4 times have occurred in an electric vehicle of a certain model. Then the probability of this model accounting for all spontaneous combustion models is 10%. Through this statistical method, it is possible to determine the models with a high proportion of spontaneous combustion vehicles, which can be identified as dangerous models. If the current charging vehicle is one of them, it needs to be adjusted to implement the charging stop strategy, that is, no The full charge is the time to stop charging, and the pre-set charging parameter threshold that can ensure safety is the time to stop charging.
(2)用于确定危险车型的方法二：(2) Method 2 for determining dangerous vehicle types:
S1-1：获取充电车辆的充电状态图像，所述充电状态图像中包括充电车辆图像；可以通过设置在充电站内的监控装置(如摄像头)来对充电车辆的图像或视频进行采集，从而能够得到充电车辆在充电状态时的图像。也可以单独在充电站内增设专用于充电车辆状态图像采集的摄像头，从而实时获取充电车辆的图像或视频。S1-1: Obtain an image of the charging state of the charging vehicle, and the charging state image includes the image of the charging vehicle; the image or video of the charging vehicle can be collected by a monitoring device (such as a camera) set in the charging station, so as to obtain Image of a charging vehicle while it is charging. It is also possible to add a camera dedicated to the image collection of the charging vehicle status in the charging station alone, so as to obtain the image or video of the charging vehicle in real time.
S1-2：根据所述充电车辆图像确定所述充电车辆的车型。通过图像处理方法，能够将充电车辆本身从图像中提取出来，进而根据充电车辆自身的相关信息来判断其车型，具体可以包括：S1-2: Determine the model of the charging vehicle according to the charging vehicle image. Through the image processing method, the charging vehicle itself can be extracted from the image, and then the vehicle type can be judged according to the relevant information of the charging vehicle itself, which may specifically include:
方式一：解析所述充电车辆图像得到所述充电车辆的轮廓；根据所述充电车辆的轮廓确定所述充电车辆的车型。根据车辆的轮廓能够确定出车辆是普通家用轿车、出租车、物流车等，同时能够估计出充电车辆的体积，进而能够判断其是否属于载重过高的物流车辆。Manner 1: analyze the image of the charging vehicle to obtain the outline of the charging vehicle; determine the type of the charging vehicle according to the outline of the charging vehicle. According to the outline of the vehicle, it can be determined whether 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 excessive load.
方式二：解析所述充电车辆图像得到所述充电车辆的车牌号码；根据所述车牌号码得到所述充电车辆的车型。也即，当确定了充电车辆的车牌号码后，能够根据车牌号码查询如交管局系统等数据库，获取充电车辆的车型，进而判断是否为危险车型。Manner 2: Obtain the license plate number of the charging vehicle by analyzing the image of the charging vehicle; and obtain the model of the charging vehicle according to the license plate number. That is, after the license plate number of the charging vehicle is determined, a database such as the traffic management bureau system can be queried according to the license plate number to obtain the type of the charging vehicle, and then determine whether it is a dangerous vehicle type.

During the APP registration process, these users need to fill in the registration information, which can include vehicle-to-model. For these users, they can directly obtain the charging process. to the user's registration information, and then extract the model reserved in the registration information as the model of the charging vehicle.
(4)用于确定危险车型的方法四(4) Method Four for Determining Dangerous Vehicles
以载重量超过载重阈值的运输车辆的车型作为所述预设危险车型。The vehicle type of the transport vehicle whose load capacity exceeds the load threshold value is used as the preset dangerous vehicle type.
以上方案中，在充电站中每一充电桩都有其特定的设备属性，在充电过程中只要充电桩正在执行充电操作其可以获得充电车辆的一些数据，例如充电时间、充电量等进而将充电数据上传至充电站的运营商平台中。因此，充电车辆在充电时是与唯一的充电桩的设备属性相关联的。当充电车辆在充电过程中，能够通过对充电数据的解析或者监控图像的解析等方式确定与充电车辆连接的充电桩是那一台，能够获得充电桩的设备属性。当确定了充电桩的设备属性之后，就能够对该充电桩进行停充策略的控制。本实施例提供一种方式：In the above scheme, each charging pile in the charging station has its specific equipment attributes. During the charging process, as long as the charging pile is performing the charging operation, it can obtain some data of the charging vehicle, such as charging time, charging amount, etc. The data is uploaded to the operator platform of the charging station. Therefore, the charging vehicle is associated with the equipment properties of the unique charging pile when charging. 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 the analysis of the monitoring image, and the equipment attributes of the charging pile can be obtained. After the equipment attributes of the charging pile are determined, the charging pile can be controlled to stop the charging strategy. This embodiment provides a way:
获取充电车辆的充电状态图像的步骤中，所述充电状态图像还包括充电桩图像；所述方法还包括如下步骤：根据所述充电桩图像确定为所述充电车辆充电的充电桩的设备属性。也即，直接根据采集到的充电车辆的充电状态图像中所记录的充电桩图像得到充电桩的设备属性。例如，根据充电桩图像得到充电桩在充电站中的具体位置，根据充电桩位置能够确定充电桩编号；或者充电桩图像中直接能够拍摄到充电桩的桩号等数据，进而得到充电桩的设备属性。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 following step: determining the device attribute of the charging pile charging the charging vehicle according to the charging pile image. That is, the device attributes of the charging pile are obtained directly according to the image of the charging pile recorded in the collected image of the charging state of the charging vehicle. For example, the specific position of the charging pile in the charging station can be obtained according to the image of the charging pile, and the number of the charging pile can be determined according to the position of the charging pile; Attributes.
以上方案中，停充参数阈值可以根据充电位温度、充电环境的湿度和车辆的电池容量来确定。基于此，本实施例还提供如图2所示的安全充电方法：In the above scheme, the threshold value of the stop-charging parameter 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：为每一预设危险车型设置对应的停充参数阈值，所述停充参数阈值是根据预设危险车型所在充电位的温度和/或充电位湿度和预设危险车型的电池容量得到的充电时长阈值或充电量阈值，所述充电量阈值小于所述电池容量。对于充电车辆来说，影响其充电安全性的主要原因是电池的温度。本步骤中，根据充电位温度和/或湿度和电池容量，设置充电时长阈值和充电量阈值能够有效地控制充电车辆的电池温度。具体设置方式，可以依据历史数据中充电时发生自燃车辆的数据分析得出合理的阈值，不同的车型、不用的电池容量可能有所不同。本实施例所述充电时长阈值tth和所述充电量阈值Qth通过如下方式得到：若T≥TG，和/或H≤HL则tth＝0，Qth＝0；若T1＜T＜TG，和/或HL＜H＜H1则tth＝t1，Qth＝Q1；若T≤T1，和/或H≥H1则tth＝t2，Qth＝Q2，且t2＞t1，Q2＞Q1；以上，T为预设危险车型所在充电位的温度，TG为充电位温度上限阈值，T1为充电位温度标准范围中的最大值，H为充电位湿度，HL为充电位湿度下限值，H1为湿度标准范围中的最小值；t1和t2分别为对应条件下的充电时长阈值，均小于所述预设危险车型电量充满所需的时间；Q1和Q2分别为对应条件下的充电量阈值，均小于所述预设危险车型电池充满时所需的电量。以上，充电位标准范围即电动车辆在充电过程中，能够确保电动车辆安全的温度范围，例如根据经验值可选择为15℃-40℃，充电位温度上限阈值为车辆可能存在很大自燃风险的温度值，可选择充电位温度标准范围中的最大值的1.5倍左右，例如充电位温度标准范围中的最大值为40℃，则充电位温度上限阈值选择为60℃左右。充电位的湿度标准范围为正常情况下湿度范围，而湿度下限值可选择为湿度标准范围中最小值的1/2左右，例如湿度标准范围为15％-60％，则湿度下限值可选择为7.5％。以上仅为举例说明，具体实现时可根据充电站的地理位置等进行适当选择。S201: Set a corresponding charge stop parameter threshold for each preset dangerous vehicle model, where the charge stop parameter threshold is obtained according to the temperature and/or the humidity of the charging location where the preset dangerous vehicle type is located and the battery capacity of the preset dangerous vehicle model A charging duration threshold or a charging amount threshold, where the charging amount threshold is smaller than the battery capacity. For a charging vehicle, the main factor affecting 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 charging vehicle. For the specific setting method, a reasonable threshold can be obtained based on the data analysis of vehicles that spontaneously combust during charging in the historical data. Different models and unused battery capacities may vary. The charging duration threshold tth and the charging amount threshold Qth in this embodiment are obtained in the following manner: if T ≥T G , and/orH ≤ HL, then tth =0, Qth =0; if T1 <T<TG , and/or HL <H <H1 , then tth =t1 , Qth =Q1 ; if T ≤ T1 , and/or H ≥ H1 , then tth =t2 , Qth =Q2 , and t2 >t1 , Q2 >Q1 ; above,T is the temperature of the charging position where the dangerous vehicle is preset, TG is the upper threshold of the temperature of the charging position, and T1 is the temperature of the charging position in the standard range The maximum value of , H is the humidity of the charging position, HL is the lower limit of the humidity of the charging position, H1 is the minimum value in the humidity standard range; t1 and t2 are the charging duration thresholds under the corresponding conditions, both less than the stated The preset time required for the battery of the dangerous vehicle to be fully charged; Q1 and Q2 are respectively the charging thresholds under corresponding conditions, which are both less than the preset amount of electricity required for the battery of the dangerous vehicle to be fully charged. The above, the standard range of the charging position is the temperature range that can ensure the safety of the electric vehicle during the charging process. For example, it can be selected as 15℃-40℃ according to the empirical value. The temperature value can be selected to be about 1.5 times the maximum value in the standard temperature range of the charging bit. For example, the maximum value in the standard temperature range of the charging bit is 40°C, and the upper limit threshold of the charging bit temperature is about 60°C. The humidity standard range of the charging position is the normal humidity range, and the humidity lower limit value can be selected to be about 1/2 of the minimum value in the humidity standard range. For example, the humidity standard range is 15%-60%, the humidity lower limit value can be The choice is 7.5%. The above is only an example, and the specific implementation can be appropriately selected according to the geographical location of the charging station.
S202：获取充电车辆的充电状态图像，所述充电状态图像中包括充电车辆图像；根据所述充电车辆图像确定所述充电车辆的车型。S202: Acquire a charging status image of a charging vehicle, where the charging status image includes a charging vehicle image; and determine a model of the charging vehicle according to the charging vehicle image.
S203：所述充电状态图像还包括充电桩图像；根据所述充电桩图像确定为所述充电车辆充电的充电桩的设备属性。S203: The charging state image further includes a charging pile image; and the device attribute of the charging pile charging the charging vehicle is determined according to the charging pile image.
S204：若所述车型与任一预设危险车型匹配，则获取与所述车型对应的停充参数阈值。S204: If the vehicle type matches any preset dangerous vehicle type, obtain a charging stop parameter threshold corresponding to the vehicle type.
S205：根据所述充电车辆的充电位温度和/或所述充电车辆所在的充电位湿度和所述充电车辆的电池容量确定与所述充电车辆对应的充电时长阈值或充电量阈值；若所述充电车辆的充电时长达到所述充电时长阈值或所述充电车辆的充电量达到所述充电量阈值则发送所述停充信号。也即，根据步骤S201中对于充电位温度、充电位湿度的区间划分，充电车辆实际充电过程中采集到的相关数值落入到哪一个区间，就以哪一类阈值作为判断停充的基准。例如，充电位温度在35℃，湿度在20％，此时对应的充电时间阈值为4小时，充电量阈值为电池容量的95％，则限定充电车辆的充电量在总容量的95％后就执行停充策略，或者当充电车辆已经充电到4小时后就控制其停止充电，并不会影响到车辆的正常运行，同时也能够进一步保证车辆的充电安全。又比如，如果充电位的温度已经达到60℃，则可能是充电车辆本身具有了很高的温度，可以推理其电池温度已经较高，此时在充电存在较高风险，这种情况下直接将充电时长阈值设置为0和充电量阈值设置为0，也就是不为充电车辆提供充电操作，以确保车辆安全。S205: Determine a charging duration threshold or a charging amount threshold corresponding to the charging vehicle according to the charging position temperature of the charging vehicle and/or the charging position humidity where the charging vehicle is located and the battery capacity of the charging vehicle; The charging stop signal is sent when the charging duration of the charging vehicle reaches the charging duration threshold or the charging volume of the charging vehicle reaches the charging volume threshold. 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 process of the charging vehicle falls into which interval, and which type of threshold is used as the criterion for judging charging stoppage. For example, if the temperature of the charging position is 35°C and the humidity is 20%, the corresponding charging time threshold is 4 hours and the charging capacity threshold is 95% of the battery capacity, then the charging capacity of the charging vehicle is limited to 95% of the total capacity. Implementing the charging stop strategy, or controlling the charging vehicle to stop charging after it has been charged for 4 hours, will not affect the normal operation of the vehicle, and 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, and it can be inferred that the battery temperature is already high. At this time, there is a high risk in charging. In this case, directly 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.
作为另一种可实现的方式，对于部分电动车辆其本身设置有测量电池温度的模块，这类电动车辆进行充电时，系统可以直接请求与充电车辆建立通信连接，当成功建立通信连接后，能够通过充电车辆的车机端直接获取到充电车辆的实时电池温度数据。此时，可以直接根据充电车辆的实时电池温度来判断是否需要停止为其充电。电池温度阈值可以选择电池正常充电时温度范围中最高值的1.2倍左右，例如电池在充电时其正常温度范围为：20℃-45℃，则电池温度阈值可以选择为54℃。充电车辆在充电过程中，可以将实时电池温度发送运营商平台，运营商平台监控电池实时温度值达到54℃后可控制停止为充电车辆充电。As another achievable way, some electric vehicles are provided with a module for measuring the battery temperature. When such electric vehicles are being charged, the system can directly request to establish a communication connection with the charging vehicle. The real-time battery temperature data of the charging vehicle is directly obtained through the on-board terminal of the charging vehicle. At this time, it can be determined whether it is necessary to stop charging the charging vehicle directly according to the real-time battery temperature of the charging vehicle. The battery temperature threshold can be selected to be about 1.2 times the highest value in the temperature range of the battery during normal charging. For example, the normal temperature range of the battery during charging is: 20°C-45°C, then the battery temperature threshold can be selected as 54°C. During the charging process of the charging vehicle, the real-time battery temperature can be sent to the operator platform, and the operator platform can control to stop charging the charging vehicle after monitoring the real-time battery temperature value reaching 54°C.
以上方案中，如图2所示，还可以包括如下步骤：In the above scheme, as shown in Figure 2, the following steps may also be included:
S206：获取与所述充电车辆关联的终端信息。本终端信息优选为乘车人员的电话号码或微信号或者安装在移动电话上的App账号信息。S206: Acquire terminal information associated with the charging vehicle. The terminal information is preferably the phone number or micro-signal of the passenger or the account information of the App installed on the mobile phone.

That is, if the charging vehicle is a dangerous vehicle, the passengers will be informed in advance, so that they can know in time that their vehicle will be restricted from charging, so that they can understand the charging time.
进一步地，上述方案在发送停充信号时还包括：Further, when sending the charging stop signal, the above solution also includes:
