[0015] Please also refer to Figure 1 and Figure 2 ,in Figure 1is a schematic block diagram of a charging pile charging safety detection system according to an embodiment of the present invention (it can also be regarded as a scenario schematic diagram of a charging pile charging safety detection method provided by an embodiment of the present invention), Figure 2 FIG. 1 is a flow chart of a charging pile charging safety detection method provided by an embodiment of the present invention. Figure 1 As shown, the charging pile charging safety detection method provided by the embodiment of the present invention is applied to the charging pile charging safety detection system, and the charging pile charging safety detection device includes a user terminal 10, a charging pile 20, a business server 30 and a safety detection server 40. The user terminal 10 is connected in communication with the business server 30 and the safety detection server 40, the charging pile 20 is connected in communication with the business server 30 and the safety detection server 40, the business server 30 is connected in communication with the safety detection server 40, and the user terminal 10 can be connected in communication with the charging pile 20. A device QR code is displayed on the outer wall or display screen of the charging pile 20. The driver of the car to be charged can use the user terminal 10 to scan the device QR code of the charging pile 20 when parking the car to be charged near the charging pile 20. After completing the above scanning operation, the communication connection between the user terminal 10 and the charging pile 20 can be established.

[0016] like Figure 2 As shown, the method includes the following steps S110-S160.

[0017] S110: If the user terminal detects that a communication connection is established with the charging pile, the user terminal obtains vehicle information of the vehicle to be charged corresponding to the vehicle to be charged, and sends the information to the charging pile.

[0018] In this embodiment, when the driver of the charging car parks the car to be charged near the charging pile, he can use the user terminal to scan the device QR code displayed on the charging pile after getting off the car. After the user terminal is authorized to log in to the charging management system provided by the business server and used for comprehensive remote management of multiple charging piles, the user terminal can first build a binding relationship between the user terminal and the charging pile. Because the vehicle information of the car to be charged (such as vehicle model, frame number, owner's name, etc.) is pre-set in the user terminal, when the user terminal detects that a communication connection is established with the charging pile, the user terminal can send the vehicle information of the car to be charged to the charging pile. In specific implementation, in addition to sending the vehicle information of the car to be charged to the charging pile, the user terminal can also send the selected scheduled charging time (such as 1h, 2h, 3h, 4h, etc.) and the charging gun number taken from the charging pile (such as charging gun No. 1, charging gun No. 2 on the charging pile, etc.) to the charging pile.

[0019] S120: When the charging pile detects that the charging gun has been plugged into the charging port of the vehicle to be charged, current charging information is obtained and sent to the service server.

[0020] The current charging information includes the charging gun ID number corresponding to the charging gun, the charging start time and the vehicle information of the vehicle to be charged.

[0021] In this embodiment, when the charging pile detects that at least one idle charging gun on it has been plugged into the charging port of the car to be charged (which can be achieved through interlock detection between the charging pile and the car to be charged), at least the charging gun ID number corresponding to the charging gun, the charging start time and the vehicle information of the car to be charged can be obtained to form the current charging information. Of course, the scheduled charging duration and other information can also be obtained and added to the current charging information. After the charging pile obtains the current charging information, it can send it to the business server to generate a charging order in the business server.

[0022] In one embodiment, before step S120, the method further includes: The charging pile establishes a TCP long connection with the business server and the safety detection server.

[0023] In this embodiment, the charging pile can establish a TCP long connection with the business server and the security detection server. For example, taking the establishment of a TCP long connection between the charging pile and the security detection server as an example, the charging pile needs to first send its device authentication information (the device authentication information is generally encrypted information) to the security detection server. After the security detection server decrypts and authenticates the device authentication information, it can establish a TCP long connection with the charging pile after determining that the charging pile is a whitelist device. Moreover, the effective duration of the TCP long connection between the charging pile and the business server and the security detection server can generally be pre-set to 30 minutes, 60 minutes, etc. When the above-mentioned charging pile and the business server or the security detection server maintain a TCP long connection state and there is no mutual data communication transmission within the time interval corresponding to the effective duration, the TCP long connection between the charging pile and the business server or the security detection server can be disconnected, and the TCP long connection can be established again when there is a data transmission demand next time.

[0024] S130: The business server generates current charging order information based on the current charging information and sends it to the safety detection server.

[0025] In this embodiment, when the business server receives the current charging information sent by the charging pile, it extracts the charging gun ID number, charging start time, vehicle information of the car to be charged, scheduled charging duration and other information, and then generates the current charging order information based on the preset order number generation strategy and sends it to the safety detection server. In this way, the current charging order information can be quickly generated in the business server based on the current charging information.

[0026] In one embodiment, if Figure 3 As shown, step S130 includes: S131, obtaining the charging gun ID number, charging start time, vehicle ID number of the car to be charged in the current charging information, and obtaining the service server device ID number; S132. Generate a current charging order number consisting of the charging gun ID number, charging start time, vehicle ID number of the car to be charged, and business server device ID number based on the order number generation strategy, and add the current charging order number to the current charging information to obtain the current charging order information.

[0027] In this embodiment, for example, the order number generation strategy is to generate the current charging order number based on the charging gun ID number + charging start time + vehicle ID number of the car to be charged in the current charging information (more specifically, it can be based on the charging gun ID number + charging start time + vehicle ID number of the car to be charged + service server device ID number), and add the current charging order number to the current charging information to obtain the current charging order information, and then send it to the security detection server. In this way, the current charging order information obtained has the uniqueness of charging order data and will not be repeated with other charging order data.

[0028] S140. The safety detection server generates current detection order information based on the current charging order information, establishes a binding relationship between the current detection order information and the current charging order information, and then sends the current detection order information to the charging pile.

[0029] In this embodiment, after the security detection server receives the current charging order information sent by the business server, it can extract the charging gun ID number, charging start time, vehicle information of the car to be charged, scheduled charging duration, charging order number, vehicle ID number of the car to be charged and business server device ID number and other information, and can also obtain the current charging order number, and then generate the current detection order information based on the preset detection order number generation strategy and send it to the charging pile. In the above manner, the current detection order information can be quickly generated based on the current charging order information in the security detection server.

[0030] In one embodiment, if Figure 4 As shown, step S140 includes: S141, obtaining the charging gun ID number, charging start time, vehicle ID number of the vehicle to be charged and the current charging order number in the current charging order information; S142. Generate a current charging inspection order number consisting of the charging gun ID number, charging start time, vehicle ID number of the car to be charged and the current charging order number based on the inspection order number generation strategy, and add the current charging inspection order number and the preset charging safety inspection strategy to the current charging order information to obtain the current inspection order information.

[0031] In this embodiment, for example, the detection order number generation strategy is to generate the current charging detection order number based on the charging gun ID number in the current charging information + charging start time + vehicle ID number of the car to be charged + current charging order number, and add the current charging detection order number and the preset charging safety detection strategy (such as the battery consistency evaluation result and battery capacity evaluation value used to detect the battery and other charging safety parameters) to the current charging order information to obtain the current detection order information, and then send it to the safety detection server. In the above manner, the current detection order information obtained has the uniqueness of the charging order data, and will not be repeated with other detection order information.

[0032] In one embodiment, before step S140, the method further includes: The safety detection server obtains charging process data corresponding to the charging pile based on the TCP long connection with the charging pile, and generates charging feature data corresponding to the vehicle to be charged based on the charging process data.

[0033] In this embodiment, in order to enable the safety detection server to more accurately determine the charging parameters of the car to be charged, a pre-charging period (such as 30 seconds) can be pre-started to enable the charging gun to charge the battery module of the car to be charged. At this time, the charging process data corresponding to the car to be charged can be obtained based on the charging gun, and then the charging pile sends the above charging process data to the safety detection server. After that, the safety detection server extracts multiple key parameters from the charging process data according to the preset charging feature data extraction strategy to form the charging feature data corresponding to the car to be charged. For example, parameters such as charging voltage, charging current, average charging power and battery capacity evaluation value (i.e., battery SOH, SOH full name is State of Health) are extracted from the charging process data for the car to be charged, and then the charging feature data corresponding to the car to be charged are formed. It can be seen that through the above method, the safety detection server can obtain several significant features corresponding to the car to be charged and form charging feature data.

[0034] S150, the charging pile receives the current detection order information, and obtains a charging parameter set of the charging gun during the charging process of the vehicle to be charged according to the charging safety detection strategy corresponding to the current detection order information, and sends the charging parameter set to the safety detection server.

[0035] In this embodiment, after the charging pile receives the current detection order information, it can obtain the charging gun ID number, charging start time, vehicle ID number of the car to be charged, current charging order number and charging safety detection strategy in the current detection order information, and can also obtain the current remaining power information of the battery module in the car to be charged. Afterwards, when the charging pile specifically charges the battery of the car to be charged, data collection can be performed based on the charging parameters required by the charging safety detection strategy to obtain the charging parameter set of the charging gun during the charging process of the car to be charged. Finally, the charging pile sends the charging parameter set to the safety detection server so that the safety detection server can perform data analysis and charging safety detection on the charging parameter set.

[0036] In one embodiment, if Figure 5 As shown, step S150 includes: S151, obtaining the charging safety detection strategy in the current detection order information; S152. According to the charging safety detection strategy, corresponding core charging parameters are collected when the charging pile charges the battery of the vehicle to be charged, to obtain the charging parameter set.

[0037] In this embodiment, for example, the core charging parameters required by the charging safety detection strategy are set to the average battery charging voltage, the average battery charging current, the average battery charging temperature and the battery voltage sequence (including multiple battery voltage values ​​collected in sequence according to a preset collection period), and the core charging parameters are determined based on the charging safety detection strategy in the current detection order information. When the charging pile charges the battery of the vehicle to be charged, the core charging parameters are continuously collected to form the charging parameter set. Afterwards, after the charging pile sends the charging parameter set to the safety detection server, the safety detection server can perform data analysis and charging safety detection on the charging parameter set.

[0038] S160. The safety detection server determines a charging safety detection result corresponding to the charging parameter set based on a preset multi-dimensional charging safety detection strategy, and sends the charging safety detection result to the user terminal.

[0039] In this embodiment, after the safety detection server obtains the charging parameter set corresponding to the vehicle to be charged, the battery capacity evaluation value can be determined based on the battery charging average voltage, battery charging average current, battery charging average temperature and other parameters, and the battery consistency evaluation result can be determined based on the battery voltage sequence, and the battery capacity evaluation value and the battery consistency evaluation result form the charging safety detection result. After the safety detection server obtains the charging safety detection result, it can be filled into the preset safety detection report template to obtain the updated charging safety detection result. Afterwards, the safety detection server sends the charging safety detection result to the user terminal, which can be timely provided for the user of the vehicle to be charged to view intuitively.

[0040] In one embodiment, if Figure 6 As shown, step S160 includes: S161, obtaining a first-dimensional charging safety detection sub-strategy in the multi-dimensional charging safety detection strategy, and determining a battery capacity evaluation value corresponding to the vehicle to be charged based on the battery charging average voltage, battery charging average current, battery charging average temperature in the charging parameter set and the first-dimensional charging safety detection sub-strategy; S162, obtaining a second-dimensional charging safety detection sub-strategy in the multi-dimensional charging safety detection strategy, and determining a battery consistency evaluation result corresponding to the vehicle to be charged based on the battery voltage sequence in the charging parameter set and the second-dimensional charging safety detection sub-strategy; S163: The battery capacity evaluation value and the battery consistency evaluation result corresponding to the vehicle to be charged are used to form the charging safety detection result.

[0041] In this embodiment, the multi-dimensional charging safety detection strategy includes at least two sub-strategies, wherein the average battery charging voltage, average battery charging current, and average battery charging temperature in the charging parameter set are used as input data of the first-dimensional charging safety detection sub-strategy, and the battery capacity evaluation value corresponding to the vehicle to be charged can be calculated and obtained. Specifically, the battery internal resistance is obtained based on the average battery charging voltage, average battery charging current, and average battery charging temperature through Kalman filtering, and then the battery capacity evaluation value corresponding to the vehicle to be charged is estimated through the battery internal resistance.

[0042] The battery voltage sequence in the charging parameter set is used as the input data of the second dimension charging safety detection sub-strategy, and the battery consistency evaluation result corresponding to the vehicle to be charged can be calculated and obtained. Specifically, the voltage standard deviation in the battery voltage sequence is first calculated, and then compared with the preset voltage threshold. For example, the preset voltage threshold is set to a voltage value close to 0. When the voltage standard deviation is less than or equal to the preset voltage threshold, the battery consistency is good as the battery consistency evaluation result; when the voltage standard deviation is greater than the preset voltage threshold, the battery consistency is poor as the battery consistency evaluation result.

[0043] It can be seen that the implementation example of the method can timely generate current charging order information in the business server and current detection order information in the safety detection server when the car to be charged is charged by plugging the charging gun of the charging pile. After that, the safety detection server receives the charging parameter set obtained by the charging pile based on the charging safety detection strategy, performs multi-dimensional charging safety detection, and obtains the charging safety detection result that characterizes the battery charging safety of the car to be charged, thereby realizing the timely acquisition of charging safety indicators during the charging process, and sending them to the user terminal for indicator viewing in a timely manner.

[0044] Figure 1 is a schematic block diagram of a charging pile charging safety detection system provided by an embodiment of the present invention. Figure 1 As shown, corresponding to the above charging pile charging safety detection method, the present invention also provides a charging pile charging safety detection system. Figure 1, the charging pile charging safety detection system includes: a user terminal 10, a charging pile 20, a business server 30 and a safety detection server 40. The user terminal 10 is connected to the business server 30 and the safety detection server 40, the charging pile 20 is connected to the business server 30 and the safety detection server 40, the business server 30 is connected to the safety detection server 40, and the user terminal 10 can be connected to the charging pile 20. A device QR code is displayed on the outer wall or display screen of the charging pile 20. The driver of the car to be charged can use the user terminal 10 to scan the device QR code of the charging pile 20 when parking the car to be charged near the charging pile 20. After completing the above scanning operation, the communication connection between the user terminal 10 and the charging pile 20 can be established.

[0045] The user terminal 10 is used to obtain vehicle information of the vehicle to be charged corresponding to the vehicle to be charged and send it to the charging pile if it detects that a communication connection is established with the charging pile.

[0046] In this embodiment, when the driver of the charging car parks the car to be charged near the charging pile, he can use the user terminal to scan the device QR code displayed on the charging pile after getting off the car. After the user terminal is authorized to log in to the charging management system provided by the business server and used for comprehensive remote management of multiple charging piles, the user terminal can first build a binding relationship between the user terminal and the charging pile. Because the vehicle information of the car to be charged (such as vehicle model, frame number, owner's name, etc.) is pre-set in the user terminal, when the user terminal detects that a communication connection is established with the charging pile, the user terminal can send the vehicle information of the car to be charged to the charging pile. In specific implementation, in addition to sending the vehicle information of the car to be charged to the charging pile, the user terminal can also send the selected scheduled charging time (such as 1h, 2h, 3h, 4h, etc.) and the charging gun number taken from the charging pile (such as charging gun No. 1, charging gun No. 2 on the charging pile, etc.) to the charging pile.

[0047] The charging pile 20 is used to detect that the charging gun has been plugged into the charging port of the car to be charged, and then obtain the current charging information and send it to the business server.

[0048] The current charging information includes the charging gun ID number corresponding to the charging gun, the charging start time and the vehicle information of the vehicle to be charged.

[0049] In this embodiment, when the charging pile detects that at least one idle charging gun on it has been plugged into the charging port of the car to be charged (which can be achieved through interlock detection between the charging pile and the car to be charged), at least the charging gun ID number corresponding to the charging gun, the charging start time and the vehicle information of the car to be charged can be obtained to form the current charging information. Of course, the scheduled charging duration and other information can also be obtained and added to the current charging information. After the charging pile obtains the current charging information, it can send it to the business server to generate a charging order in the business server.

[0050] In one embodiment, the charging pile 20 is also used for: A TCP long connection is established with both the business server and the security detection server.

[0051] In this embodiment, the charging pile can establish a TCP long connection with the business server and the security detection server. For example, taking the establishment of a TCP long connection between the charging pile and the security detection server as an example, the charging pile needs to first send its device authentication information (the device authentication information is generally encrypted information) to the security detection server. After the security detection server decrypts and authenticates the device authentication information, it can establish a TCP long connection with the charging pile after determining that the charging pile is a whitelist device. Moreover, the effective duration of the TCP long connection between the charging pile and the business server and the security detection server can generally be pre-set to 30 minutes, 60 minutes, etc. When the above-mentioned charging pile and the business server or the security detection server maintain a TCP long connection state and there is no mutual data communication transmission within the time interval corresponding to the effective duration, the TCP long connection between the charging pile and the business server or the security detection server can be disconnected, and the TCP long connection can be established again when there is a data transmission demand next time.

[0052] The business server 30 is used to generate current charging order information based on the current charging information and send it to the safety detection server.

[0053] In this embodiment, when the business server receives the current charging information sent by the charging pile, it extracts the charging gun ID number, charging start time, vehicle information of the car to be charged, scheduled charging duration and other information, and then generates the current charging order information based on the preset order number generation strategy and sends it to the safety detection server. In this way, the current charging order information can be quickly generated in the business server based on the current charging information.

[0054] In one embodiment, the service server 30 is specifically used for: Obtain the charging gun ID number, charging start time, vehicle ID number of the car to be charged in the current charging information, and obtain the service server device ID number; Based on the order number generation strategy, a current charging order number consisting of the charging gun ID number, charging start time, vehicle ID number of the car to be charged, and business server device ID number is generated, and the current charging order number is added to the current charging information to obtain the current charging order information.

[0055] In this embodiment, for example, the order number generation strategy is to generate the current charging order number based on the charging gun ID number + charging start time + vehicle ID number of the car to be charged in the current charging information (more specifically, it can be based on the charging gun ID number + charging start time + vehicle ID number of the car to be charged + service server device ID number), and add the current charging order number to the current charging information to obtain the current charging order information, and then send it to the security detection server. In this way, the current charging order information obtained has the uniqueness of charging order data and will not be repeated with other charging order data.

[0056] The safety detection server 40 is used to generate current detection order information based on the current charging order information, establish a binding relationship between the current detection order information and the current charging order information, and then send the current detection order information to the charging pile.

[0057] In this embodiment, after the security detection server receives the current charging order information sent by the business server, it can extract the charging gun ID number, charging start time, vehicle information of the car to be charged, scheduled charging duration, charging order number, vehicle ID number of the car to be charged and business server device ID number and other information, and can also obtain the current charging order number, and then generate the current detection order information based on the preset detection order number generation strategy and send it to the charging pile. In the above manner, the current detection order information can be quickly generated based on the current charging order information in the security detection server.

[0058] In one embodiment, the security detection server 40 is specifically used for: Obtain the charging gun ID number, charging start time, vehicle ID number of the vehicle to be charged and the current charging order number in the current charging order information; Based on the inspection order number generation strategy, a current charging inspection order number consisting of the charging gun ID number, charging start time, vehicle ID number of the car to be charged and the current charging order number is generated, and the current charging inspection order number and the preset charging safety inspection strategy are added to the current charging order information to obtain the current inspection order information.

[0059] In this embodiment, for example, the detection order number generation strategy is to generate the current charging detection order number based on the charging gun ID number in the current charging information + charging start time + vehicle ID number of the car to be charged + current charging order number, and add the current charging detection order number and the preset charging safety detection strategy (such as the battery consistency evaluation result and battery capacity evaluation value used to detect the battery and other charging safety parameters) to the current charging order information to obtain the current detection order information, and then send it to the safety detection server. In the above manner, the current detection order information obtained has the uniqueness of the charging order data, and will not be repeated with other detection order information.

[0060] In one embodiment, the security detection server 40 is further used for: Based on the TCP long connection with the charging pile, the charging process data corresponding to the charging pile is acquired, and the charging characteristic data corresponding to the vehicle to be charged is generated based on the charging process data.

[0061] In this embodiment, in order to enable the safety detection server to more accurately determine the charging parameters of the car to be charged, a pre-charging period (such as 30 seconds) can be pre-started to enable the charging gun to charge the battery module of the car to be charged. At this time, the charging process data corresponding to the car to be charged can be obtained based on the charging gun, and then the charging pile sends the above charging process data to the safety detection server. After that, the safety detection server extracts multiple key parameters from the charging process data according to the preset charging feature data extraction strategy to form the charging feature data corresponding to the car to be charged. For example, parameters such as charging voltage, charging current, average charging power and battery capacity evaluation value (i.e., battery SOH, SOH full name is State of Health) are extracted from the charging process data for the car to be charged, and then the charging feature data corresponding to the car to be charged are formed. It can be seen that through the above method, the safety detection server can obtain several significant features corresponding to the car to be charged and form charging feature data.

[0062] The charging pile 20 is also used to receive the current detection order information, and obtain the charging parameter set of the charging gun during the charging process of the vehicle to be charged according to the charging safety detection strategy corresponding to the current detection order information, and send the charging parameter set to the safety detection server.

[0063] In this embodiment, after the charging pile receives the current detection order information, it can obtain the charging gun ID number, charging start time, vehicle ID number of the car to be charged, current charging order number and charging safety detection strategy in the current detection order information, and can also obtain the current remaining power information of the battery module in the car to be charged. Afterwards, when the charging pile specifically charges the battery of the car to be charged, data collection can be performed based on the charging parameters required by the charging safety detection strategy to obtain the charging parameter set of the charging gun during the charging process of the car to be charged. Finally, the charging pile sends the charging parameter set to the safety detection server so that the safety detection server can perform data analysis and charging safety detection on the charging parameter set.

[0064] In one embodiment, the charging pile 20 is specifically used for: Obtain the charging safety detection strategy in the current detection order information; According to the charging safety detection strategy, corresponding core charging parameters are collected when the charging pile charges the battery of the vehicle to be charged, so as to obtain the charging parameter set.

[0065] In this embodiment, for example, the core charging parameters required by the charging safety detection strategy are set to the average battery charging voltage, the average battery charging current, the average battery charging temperature and the battery voltage sequence (including multiple battery voltage values ​​collected in sequence according to a preset collection period), and the core charging parameters are determined based on the charging safety detection strategy in the current detection order information. When the charging pile charges the battery of the vehicle to be charged, the core charging parameters are continuously collected to form the charging parameter set. Afterwards, after the charging pile sends the charging parameter set to the safety detection server, the safety detection server can perform data analysis and charging safety detection on the charging parameter set.

[0066] The safety detection server 40 is used to determine the charging safety detection result corresponding to the charging parameter set based on a preset multi-dimensional charging safety detection strategy, and send the charging safety detection result to the user terminal.

[0067] In this embodiment, after the safety detection server obtains the charging parameter set corresponding to the vehicle to be charged, the battery capacity evaluation value can be determined based on the battery charging average voltage, battery charging average current, battery charging average temperature and other parameters, and the battery consistency evaluation result can be determined based on the battery voltage sequence, and the battery capacity evaluation value and the battery consistency evaluation result form the charging safety detection result. After the safety detection server obtains the charging safety detection result, it can be filled into the preset safety detection report template to obtain the updated charging safety detection result. Afterwards, the safety detection server sends the charging safety detection result to the user terminal, which can be timely provided for the user of the vehicle to be charged to view intuitively.

[0068] In one embodiment, the security detection server 40 is specifically used for: Obtaining a first-dimensional charging safety detection sub-strategy in the multi-dimensional charging safety detection strategy, and determining a battery capacity evaluation value corresponding to the vehicle to be charged based on an average battery charging voltage, an average battery charging current, an average battery charging temperature in the charging parameter set and the first-dimensional charging safety detection sub-strategy; Obtaining a second-dimensional charging safety detection sub-strategy in the multi-dimensional charging safety detection strategy, and determining a battery consistency evaluation result corresponding to the vehicle to be charged based on the battery voltage sequence in the charging parameter set and the second-dimensional charging safety detection sub-strategy; The charging safety detection result is composed of the battery capacity evaluation value and the battery consistency evaluation result corresponding to the vehicle to be charged.

[0069] In this embodiment, the multi-dimensional charging safety detection strategy includes at least two sub-strategies, wherein the average battery charging voltage, average battery charging current, and average battery charging temperature in the charging parameter set are used as input data of the first-dimensional charging safety detection sub-strategy, and the battery capacity evaluation value corresponding to the vehicle to be charged can be calculated and obtained. Specifically, the battery internal resistance is obtained based on the average battery charging voltage, average battery charging current, and average battery charging temperature through Kalman filtering, and then the battery capacity evaluation value corresponding to the vehicle to be charged is estimated through the battery internal resistance.

[0070] The battery voltage sequence in the charging parameter set is used as the input data of the second dimension charging safety detection sub-strategy, and the battery consistency evaluation result corresponding to the vehicle to be charged can be calculated and obtained. Specifically, the voltage standard deviation in the battery voltage sequence is first calculated, and then compared with the preset voltage threshold. For example, the preset voltage threshold is set to a voltage value close to 0. When the voltage standard deviation is less than or equal to the preset voltage threshold, the battery consistency is good as the battery consistency evaluation result; when the voltage standard deviation is greater than the preset voltage threshold, the battery consistency is poor as the battery consistency evaluation result.

[0071] It can be seen that the implementation example of the device can timely generate current charging order information in the business server and current detection order information in the safety detection server when the car to be charged is charged by plugging the charging gun of the charging pile. After that, the safety detection server receives the charging parameter set obtained by the charging pile based on the charging safety detection strategy, performs multi-dimensional charging safety detection, and obtains the charging safety detection result that characterizes the battery charging safety of the car to be charged, thereby realizing timely acquisition of charging safety indicators during the charging process, and timely sending them to the user terminal for indicator viewing.
