Example one
Fig. 1 is a flowchart of a charging station safety protection method according to an embodiment of the present invention, and as shown in fig. 1, the method specifically includes the following steps:
step S102, after the charging connection is established between the charging vehicle and the charging equipment in the target charging station, whether the charging vehicle is a high-risk vehicle is judged based on the interactive data between the charging vehicle and the charging equipment.
The charging station safety protection method provided by the embodiment of the invention is applied to a charging station safety protection system, and the charging station safety protection system comprises a plurality of subsystems: the system comprises a charging station barrier gate subsystem, a charging guide subsystem, a charging control subsystem, a charging early warning subsystem and a safety evaluation subsystem. And the plurality of subsystems can share and link information.
The embodiment of the invention firstly introduces how to perform safety protection on the target charging station from the perspective of the charging control subsystem. After the charging connection is established between the charging vehicle and the charging equipment in the target charging station, the operation of charging the charging vehicle is about to be executed, in order to ensure the charging safety of the charging vehicle in the charging process, firstly, whether the charging vehicle is a high-risk vehicle is judged by using interaction data between the charging vehicle and the charging equipment, wherein the charging control subsystem can determine the vehicle type and the vehicle health state of the charging vehicle according to the interaction data between the charging vehicle and the charging equipment, and if the current charging vehicle is connected to any one charging equipment in the overcharge station safety protection system for charging, the charging file of the charging vehicle is stored in the charging station safety protection system, and the charging control subsystem also acquires the charging file according to the interaction data and an information sharing linkage strategy in the system. The embodiment of the invention does not specifically limit the method for determining the vehicle health state according to the interactive data, and the user can set the vehicle health evaluation index in a user-defined manner according to the actual requirement so as to obtain the vehicle health state score.
In the embodiment of the invention, after the charging of the charging vehicle is finished each time, the charging control subsystem analyzes the data generated by the charging vehicle in the charging process, and further evaluates the safety coefficient of the charging vehicle to determine whether the charging vehicle belongs to a high-risk vehicle and counts the safety coefficient into the charging file of the charging vehicle, wherein the high-risk vehicle represents a vehicle with a preset potential safety hazard. According to the embodiment of the invention, the specific hidden danger types of the preset potential safety hazards are not specifically limited, and a user can set the hidden danger types according to actual requirements so as to judge whether the charging vehicle belongs to a high-risk vehicle. For example, the high-risk vehicle may be a vehicle with a state of health score below a preset threshold.
If the charging vehicle is a high-risk vehicle, executing the following step S104; if the charging vehicle is not a high-risk vehicle, the following step S106 is executed.
And step S104, determining the charging limiting strategy of the charging vehicle based on the vehicle type and the health state of the charging vehicle.
And step S106, determining a corresponding standard charging strategy for the charging vehicle based on the vehicle type of the charging vehicle.
And S108, analyzing the charging parameters of the charging vehicle based on a preset charging parameter sample library in the charging process of the charging vehicle to obtain an analysis result, and adjusting the charging strategy of the charging vehicle based on the analysis result.
Specifically, if the charging vehicle cannot be determined to be a high-risk vehicle according to the interactive data, the charging control subsystem determines a corresponding standard charging strategy for the charging vehicle according to the vehicle type of the charging vehicle, namely, performs charging processing according to a normal vehicle; on the contrary, if the charging control subsystem determines that the charging vehicle is a high-risk vehicle, the charging control subsystem determines a corresponding charging limiting strategy for the charging vehicle according to the vehicle type and the health state of the charging vehicle, and in the embodiment of the invention, the charging limiting strategy comprises the following steps: the charging is stopped, and the maximum value of the charging current and the maximum value of the State of charge (SOC) are limited.
It can be understood that if the vehicle belongs to a high-risk vehicle, but the state of health of the vehicle is relatively good, the charging safety of the charging vehicle can be guaranteed by limiting the maximum value of the charging SOC of the vehicle; if the vehicle belongs to a high-risk vehicle, but the health state of the vehicle is relatively poor, the charging safety of the charging vehicle can be guaranteed by limiting the maximum value of the charging current; if the vehicle belongs to a high-risk vehicle and the health state of the vehicle is extremely poor, the charging control subsystem determines that the safety of the charging process cannot be ensured through the two limiting measures, and then the charging limiting strategy is set to stop charging, namely, the charging equipment is controlled not to supply power for the charging vehicle. The above description is only an exemplary description of the selection manner of the charging-limitation policy, and the user may also set a corresponding trigger condition for each charging-limitation policy according to actual needs, and the embodiment of the present invention does not specifically set the trigger condition.
After configuring the corresponding charging strategy for the charging vehicle, the charging device can charge the charging vehicle based on the corresponding charging strategy under the control of the charging control subsystem, and in order to further guarantee the charging safety of the charging vehicle, in the charging process of the charging vehicle, the charging control subsystem analyzes the charging parameters of the charging vehicle based on a preset charging parameter sample library, and continuously adjusts the charging strategy of the charging vehicle according to the analysis result to prevent safety accidents. The preset charging parameter sample library is a database in which multiple charging parameters of various vehicle types are stored.
For example, if the initial charging-limiting strategy configured by the charging control subsystem for the charging vehicle is the maximum charging-limiting current value, or the charging strategy configured by the charging control subsystem for the charging vehicle is the standard charging strategy, but in the actual charging process, the analysis result shows that serious abnormal conditions continuously occur in the charging parameters of the charging vehicle, the charging control subsystem immediately issues a charging-terminating instruction to the charging device connected to the charging vehicle, that is, the charging-limiting strategy of the charging device is adjusted from the maximum charging-limiting current value to charging-terminating, or from the standard charging strategy to charging-terminating, so as to avoid charging safety accidents.
The invention provides a safety protection method for a charging station, which comprises the following steps: after the charging connection is established between the charging vehicle and charging equipment in the target charging station, judging whether the charging vehicle is a high-risk vehicle or not based on the interactive data between the charging vehicle and the charging equipment; the high-risk vehicle represents a vehicle with a preset potential safety hazard; if the charging vehicle is a high-risk vehicle, determining a charging limiting strategy of the charging vehicle based on the vehicle type and the health state of the charging vehicle; in the charging process of the charging vehicle, the charging parameters of the charging vehicle are analyzed based on a preset charging parameter sample library to obtain an analysis result, and the charging strategy of the charging vehicle is adjusted based on the analysis result.
According to the charging station safety protection method provided by the invention, after the charging connection is established between the charging vehicle and the charging equipment in the target charging station, whether the charging vehicle is a high-risk vehicle is determined according to the interactive data between the charging vehicle and the charging equipment, under the condition that the charging vehicle is determined to be the high-risk vehicle, the charging-limited strategy of the charging vehicle is determined according to the vehicle type and the health state of the charging vehicle, in addition, in the charging process, the charging parameters of the charging vehicle are analyzed by utilizing a preset charging parameter sample library, and the charging strategy of the charging vehicle is adjusted based on the analysis result. By utilizing the safety protection method for the charging station, provided by the invention, the abnormal condition of the charging vehicle can be found early, and early prevention and early treatment can be realized, so that the occurrence probability of safety accidents of the charging station is effectively reduced.
In an optional embodiment, as shown in fig. 2, in the step S106, analyzing the charging parameter of the charging vehicle based on a preset charging parameter sample library to obtain an analysis result, and adjusting the charging strategy of the charging vehicle based on the analysis result, specifically includes the following steps:
step S1061, judging whether the maximum deviation between the charging parameter of the charging vehicle and the average charging parameter of the vehicles of the same model in the preset charging parameter sample library is greater than a preset threshold value.
If yes, executing the following steps S1062 to S1063; if not, the following step S1064 is performed.
Step S1062, obtaining a variation of the charging parameter in a preset monitoring period.
In step S1063, the charging policy of the charging vehicle is adjusted based on the variation and the preset limit charging policy table.
Step S1064, maintaining the original charging policy of the charging vehicle.
Specifically, after charging is started, the real-time computing platform of the charging control subsystem performs comparative analysis on the charging parameters of the charging vehicle and a preset charging parameter sample library to judge whether the maximum deviation between the charging parameters of the charging vehicle and the average charging parameters of vehicles of the same type is greater than a preset threshold value, wherein the charging parameters comprise: the maximum temperature of the cells and/or the temperature difference between the cells. If the charging strategy is not larger than the preset charging strategy, the charging safety of the charging vehicle can be ensured under the current charging strategy, and therefore, the charging control subsystem maintains the original charging strategy of the charging vehicle.
If the maximum deviation is greater than the preset threshold, it is indicated that potential safety hazards exist in the charging safety of the charging vehicle, and at this time, a corresponding control instruction needs to be further issued to the charging equipment according to the severity of the potential safety hazards to adjust the charging strategy of the charging vehicle. The user can set a plurality of value intervals of the charging parameter variation according to actual requirements, and set a corresponding charging limiting strategy for each value interval.
For example, if the variation of the charging parameter in the preset monitoring period exceeds the preset maximum value, the charging control subsystem immediately issues a charging termination instruction; if the variation of the charging parameter in a preset monitoring period is smaller than a preset maximum limit value but larger than a preset middle limit value (wherein the preset maximum limit value is larger than the preset middle limit value), further reducing the maximum charging current of the charging vehicle on the basis of a current limiting strategy, and if the abnormal phenomenon is found to be controlled through monitoring, maintaining the charging by using the reduced charging current; however, if the abnormal phenomenon is found through monitoring and is not controlled by reducing the charging current, that is, the variation of the charging parameter in the preset monitoring period is continuously abnormal, the charging control subsystem will immediately issue a command for stopping charging.
The embodiment of the invention does not specifically limit the duration of the preset monitoring period and the preset threshold, and a user can set the duration according to actual requirements. In order to ensure the charging safety of the charging vehicle, the above steps can be selected to be periodically executed during the charging process of the vehicle.
The above description of the embodiments of the present invention describes how to safeguard a target charging station from the perspective of the charging control subsystem, and the following description describes how to safeguard a target charging station from the perspective of the charging station barrier subsystem and the charging guidance subsystem.
In an alternative embodiment, before the charging vehicle establishes the charging connection with the charging device in the target charging station, the method further includes the following steps:
step S201, after the charging vehicle enters an entrance barrier identification area of a target charging station, judging whether the charging vehicle is a high-risk vehicle according to the license plate number of the charging vehicle.
If yes, executing the following step S202; if not, the following step S203 is executed.
And step S202, judging whether the charging vehicle is allowed to enter the target charging station according to the safety level label of the target charging station.
In step S203, the charging vehicle is allowed to enter the target charging station.
In the case where the charging vehicle is allowed to enter the target charging station, the following step S204 is executed.
And step S204, distributing corresponding charging equipment to the charging vehicle based on the vehicle type of the charging vehicle and the charging required power.
In the above description, if a charging vehicle is once connected to any one charging device in the overcharge station safety protection system for charging, the charging station safety protection system stores the charging file of the charging vehicle, and according to the information sharing linkage strategy, all subsystems included in the protection system can acquire the charging file information of all charging vehicles, where the charging file information includes: the license plate number of the charging vehicle, whether the charging vehicle is a high-risk vehicle and the like.
Therefore, after the charging vehicle enters the entrance barrier identification area of the target charging station, the charging station barrier subsystem can preliminarily judge whether the charging vehicle is a high-risk vehicle according to the license plate number of the charging vehicle, if the charging vehicle cannot be determined to be the high-risk vehicle, the charging station barrier subsystem will permit the charging vehicle to enter the target charging station, and the charging guidance subsystem will allocate corresponding charging equipment to the charging vehicle according to the vehicle type and the charging demand power of the charging vehicle.
If the charging station barrier gate subsystem determines that the charging vehicle is a high-risk vehicle, whether the charging vehicle is allowed to enter the target charging station needs to be further judged according to the safety class label of the target charging station. In the embodiment of the present invention, the charging station safety protection system configures corresponding safety class tags for all charging stations in the jurisdiction range thereof, and specifically includes: the charging station with the high safety level does not allow the high-risk vehicles to enter, and the charging station with the low safety level allows the high-risk vehicles to enter. Charging stations with high safety levels such as those in special areas of gas stations, airports and the like.
If the safety level label of the target charging station is a high safety level label, the charging station barrier gate subsystem refuses the high-risk vehicle to enter the target charging station; if the security level tag of the target charging station is a low security level tag, the charging station barrier subsystem allows the high-risk vehicle to enter the target charging station. And the charging guidance subsystem can distribute corresponding charging equipment to the charging vehicle according to the vehicle type and the charging demand power of the charging vehicle.
In an optional embodiment, in step S204, allocating a corresponding charging device to the charging vehicle based on the vehicle type of the charging vehicle and the charging demand power specifically includes the following steps:

If the charging vehicle is not a high-risk vehicle, distributing second charging equipment for the charging vehicle based on the vehicle type and the charging required power of the charging vehicle; and the charging power of the second charging equipment is equal to the charging demand power.
As can be seen from the above description, when the charging vehicle is not a high-risk vehicle, the charging guidance subsystem allocates a matching second charging device to the charging vehicle according to the vehicle type of the charging vehicle and the charging demand power thereof, and the charging power of the second charging device is equal to the charging demand power, that is, the system can meet the actual charging demand of the charging vehicle. In the embodiment of the present invention, the second charging device may be a device that satisfies the above conditions, or may be a charging device specified by the charging guidance subsystem. When the charging vehicle drives into a charging parking space of the second charging equipment meeting the conditions, the charging guidance subsystem controls the ground lock on the parking space to automatically descend; otherwise, the ground lock on the parking space cannot automatically fall.
When the charging vehicle is a high-risk vehicle, the charging guidance subsystem allocates a first charging device matched with the charging vehicle according to the vehicle type of the charging vehicle and the charging demand power of the charging vehicle, and the charging power of the first charging device is smaller than the charging demand power, that is, the system allocates a charging device (slow charging parking space) with low-power charging to the charging vehicle. When the charging vehicle drives into a charging parking space of the first charging equipment meeting the conditions, the charging guidance subsystem controls the ground lock on the parking space to automatically descend; otherwise, the ground lock on the parking space cannot automatically fall.
For example, if the charging demand power of the non-high-risk vehicle of the same vehicle type is a, but since the charging vehicle is a high-risk vehicle, the charging guidance subsystem may allocate a charging device with a charging power less than a to the charging guidance subsystem from a safety point of view. And after the charging vehicle reaches the appointed charging parking space, the charging guide subsystem automatically descends the control ground lock, so that the charging vehicle can enter the parking space, and then the charging connection is established with the charging equipment to start charging.
In the above, the embodiments of the present invention describe how to perform safety protection on the target charging station from the perspective of the charging station barrier subsystem and the charging guidance subsystem, and in the following, describe how to perform safety protection on the target charging station from the perspective of the charging station early warning subsystem.
