[0002] With the widespread popularity of new energy vehicles, new energy vehicles have an increasing demand for charging, and at the same time, the requirements for charging efficiency are also getting higher and higher. In order to improve the charging efficiency, the charging current must be increased, and the temperature rise rate of the charging process will also increase accordingly. In order to slow down the temperature rise during the charging process, the charging gun liquid cooling system came into being. The liquid cooling system can timely remove the temperature generated by the charging gun during charging by driving the coolant circulation therein, thereby increasing the charging current that the charging gun can carry. In the related art, the control method of the liquid cooler in the charging gun liquid cooling system is mainly based on the change of the liquid cooling temperature inside the liquid cooler to adjust the speed of the liquid cooler.

[0025] See also Figure 1 , Figure 1 is a schematic diagram of an application environment according to an exemplary embodiment. Figure 1 As shown, the application environment may include a server 01 and a terminal 02 .

[0026] In an optional embodiment, the server 01 can perform calculations on the charging device control method. Specifically, the server 01 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

Specifically, the terminal 02 may be a controller or control module configured in the charging and swapping station where the charging device is located.

[0028] For example, the temperature information corresponding to the charging gun head of the charging device is obtained through terminal 02 and transmitted to server 01. Server 01 receives the temperature information. When the temperature information is less than the first preset temperature threshold, based on the preset temperature-speed correspondence relationship, the liquid cooler speed information corresponding to the temperature information is determined and transmitted to terminal 02. Terminal 02 controls the operation of the liquid cooler of the charging device based on the liquid cooler speed information.

[0029] In addition, it should be noted that Figure 1 What is shown is only one application environment provided by the present disclosure. In actual application, other application environments may also be included.

[0030] In the embodiments of this specification, the server 01 and the terminal 02 may be directly or indirectly connected via wired or wireless communication, which is not limited in this disclosure.

[0031] Figure 2 is a flow chart of a charging device control method according to an exemplary embodiment. Figure 2 As shown, the charging device control method includes the following: Step S201: Obtain temperature information corresponding to the charging gun head of the charging device.

[0032] In the embodiments of the present disclosure, the charging device may be a device that supplies power to a vehicle powered by a battery, such as a charging gun, a charging pile, etc. The vehicle may be an electric car, an electric bicycle, etc.

[0033] Figure 3 FIG. 1 is a perspective view of a charging gun head according to an exemplary embodiment. Figure 3 As shown, the DC+ and DC- in the charging gun head are power lines, DC+ is the positive power line, and DC- is the negative power line. When the charging gun head supplies power to the vehicle to be charged, DC+ and DC- are connected to the positive and negative input terminals of the vehicle respectively. Therefore, the main temperature generated during the charging process is the temperature rise of the power line at the charging gun head. The temperature data collection of the charging gun head can be achieved by pre-buried in the charging gun through insulation treatment and close to DC+ and DC- respectively. Temperature probe 1 and temperature probe 2 can accurately feedback the temperature of DC+ and DC-. Temperature probe 1 and temperature probe 2 are respectively connected with lead wires to report the collected temperature data in real time.

[0034] In the embodiment of the present disclosure, the temperature information corresponding to the charging gun head of the charging device can be obtained by having the temperature probe 1 and the temperature probe 2 collect temperature data once at a certain interval, such as once every 3 seconds or 5 seconds, and report it to the processing terminal. The processing terminal uses the average value of the temperature data collected by the temperature probe 1 and the temperature probe 2 respectively received in real time as the temperature information corresponding to the charging gun head at that moment.

[0035] The temperature information corresponding to the charging gun head of the charging device can also be obtained by performing multiple samplings by the temperature probe 1 and the temperature probe 2 respectively within a sampling period, and reporting to the processing terminal. The processing terminal uses the average value of the temperature data collected by the temperature probe 1 and the temperature probe 2 received within the sampling period as the temperature information corresponding to the charging gun head within the sampling period. In order to prevent the influence of abnormal data (such as data jumps caused by sudden data analysis anomalies) on the temperature information, the highest temperature data and the lowest temperature data within a sampling period can be deleted, and then the remaining temperature data can be averaged to obtain the temperature information corresponding to the charging gun head within the sampling period to improve the accuracy of the temperature information. Exemplarily, a sampling period can be 10 seconds, 20 seconds, etc. In a sampling period, the temperature probe 1 and the temperature probe 2 can be sampled once every 1 second to achieve multiple sampling within a sampling period. Temperature sampling is performed by the temperature probe at the charging gun head, and there is no need to add an additional sampling path, which is more convenient for the implementation of the charging device control method in this embodiment.

[0036] Step S202: when the temperature information is less than a first preset temperature threshold, based on a preset temperature-speed correspondence relationship, determine the liquid cooling machine speed information corresponding to the temperature information.

[0037] In the disclosed embodiment, the value of the first preset temperature threshold can be set to the highest temperature value within the safe charging temperature range of the charging gun head. When the temperature information is less than the highest temperature value, the liquid cooler speed information corresponding to the temperature information is determined based on the preset temperature-speed correspondence. The preset temperature-speed correspondence reflects the correspondence between the temperature information corresponding to the charging gun head and the liquid cooler speed information. The liquid cooler speed information is used to indicate the liquid cooler speed required to reduce the charging gun head from the temperature information to the target temperature information. The liquid cooler is used to drive the coolant to circulate to take away the heat generated by the charging gun head. The higher the speed of the liquid cooler, the faster the coolant flow rate, and the more heat is taken away. The temperature corresponding to the target temperature information is lower than the temperature corresponding to the temperature information.

[0038] The preset temperature-speed correspondence relationship may be a curve reflecting the relationship between the temperature information corresponding to the charging gun head and the liquid cooler speed information. In this case, the liquid cooler speed information corresponding to different temperature information is respectively different liquid cooler speed values, and the higher the temperature information, the higher the corresponding liquid cooler speed information. The liquid cooler speed value corresponding to the temperature information obtained by the curve is determined as the liquid cooler speed information corresponding to the temperature information.

[0039] The preset temperature-speed correspondence relationship can also be an expression that reflects the conversion relationship between the temperature information corresponding to the charging gun head and the liquid cooler speed information. In this case, the liquid cooler speed information corresponding to different temperature information is different liquid cooler speed values. The higher the temperature information, the higher the corresponding liquid cooler speed information. Substitute the temperature information into the liquid cooler speed value calculated by the expression to determine the liquid cooler speed information corresponding to the temperature information.

[0040] The preset temperature-speed correspondence may also be a statistical table reflecting the relationship between the temperature information corresponding to the charging gun head and the liquid cooler speed information. In this case, the liquid cooler speed information corresponding to different temperature information may be different liquid cooler speed values, and the liquid cooler speed information corresponding to different temperature information may also be different liquid cooler speed ranges. The liquid cooler speed range corresponding to the temperature information is obtained by looking up the table, and the liquid cooler speed range is determined as the liquid cooler speed information corresponding to the temperature information.

[0041] In an optional embodiment, the preset temperature-speed correspondence may include a preset temperature-flow rate correspondence and a preset flow rate-speed correspondence, and based on the preset temperature-speed correspondence, determining the liquid cooler speed information corresponding to the temperature information further includes: Step S2021: Based on a preset temperature-flow rate correspondence, determine the coolant flow rate information corresponding to the temperature information.

[0042] In the disclosed embodiment, the preset temperature-flow rate correspondence reflects the correspondence between the temperature information corresponding to the charging gun head and the coolant flow rate information. The coolant flow rate information is used to indicate the coolant flow rate required to reduce the temperature information of the charging gun head to the target temperature information. The temperature corresponding to the target temperature information is lower than the temperature corresponding to the temperature information.

[0043] The preset temperature-flow rate correspondence relationship may be a curve reflecting the relationship between the temperature information corresponding to the charging gun head and the coolant flow rate information. In this case, the coolant flow rate information corresponding to different temperature information is respectively different coolant flow rate values, and the higher the temperature information, the higher the corresponding coolant flow rate information. The coolant flow rate value corresponding to the temperature information obtained by the curve is determined as the coolant flow rate information corresponding to the temperature information.

[0044] The preset temperature-flow rate correspondence relationship can also be an expression that reflects the conversion relationship between the temperature information corresponding to the charging gun head and the coolant flow rate information. In this case, the coolant flow rate information corresponding to different temperature information is different coolant flow rate values. The higher the temperature information, the higher the corresponding coolant flow rate information. Substitute the temperature information into the coolant flow rate value calculated by the expression to determine the coolant flow rate information corresponding to the temperature information.

[0045] The preset temperature-flow rate correspondence may also be a statistical table reflecting the relationship between the temperature information corresponding to the charging gun head and the coolant flow rate information. In this case, the coolant flow rate information corresponding to different temperature information may be different coolant flow rate values, and the coolant flow rate information corresponding to different temperature information may also be different coolant flow rate intervals. The coolant flow rate value or coolant flow rate interval corresponding to the temperature information is obtained by looking up the table, and the coolant flow rate value or coolant flow rate interval is determined as the coolant flow rate information corresponding to the temperature information.

[0046] Step S2022: Based on the preset flow rate and rotation speed correspondence relationship, determine the liquid cooling machine rotation speed information corresponding to the coolant flow rate information.

[0047] In the embodiment of the present disclosure, the preset flow rate and speed correspondence reflects the correspondence between the coolant flow rate information and the liquid cooler speed information, and the liquid cooler speed information is used to indicate the liquid cooler speed corresponding to the flow rate indicated by the coolant flow rate information when the liquid cooler drives the coolant to the flow rate indicated by the coolant flow rate information.

[0048] The preset flow rate and speed correspondence relationship may be a curve reflecting the relationship between the coolant flow rate information and the liquid cooler speed information. In this case, the liquid cooler speed information corresponding to different coolant flow rate information is respectively different liquid cooler speed values, and the higher the coolant flow rate information, the higher the corresponding liquid cooler speed information. The liquid cooler speed value corresponding to the coolant flow rate information obtained by the curve is determined as the liquid cooler speed information corresponding to the coolant flow rate information.

[0049] The preset flow rate and speed correspondence relationship may also be an expression reflecting the conversion relationship between the coolant flow rate information and the liquid cooler speed information. In this case, the liquid cooler speed information corresponding to different coolant flow rate information is respectively different liquid cooler speed values, and the higher the coolant flow rate information, the higher the corresponding liquid cooler speed information. The coolant flow rate information is substituted into the liquid cooler speed value calculated by the expression, and the liquid cooler speed information corresponding to the coolant flow rate information is determined.

[0050] The preset flow rate and speed correspondence relationship may also be a statistical table reflecting the relationship between the coolant flow rate information and the liquid cooler speed information. In this case, the liquid cooler speed information corresponding to different coolant flow rate information may be different liquid cooler speed values. The liquid cooler speed value corresponding to the coolant flow rate information is obtained by looking up the table, and the coolant flow rate value is determined as the liquid cooler speed information corresponding to the coolant flow rate information.

[0051] Based on the above, it can be known that the embodiment of the present disclosure can determine the coolant flow rate information that matches the current temperature information by the relationship between the gun tip temperature and the coolant flow rate reflected by the preset temperature-flow rate correspondence, so that the coolant can take away the heat that the current charging gun tip needs to dissipate at the coolant flow rate indicated by the coolant flow rate information; by the relationship between the coolant flow rate and the liquid cooler speed reflected by the preset flow rate-speed correspondence, it can determine the liquid cooler speed information that matches the current coolant flow rate information, so that the liquid cooler can drive the coolant to reach the flow rate indicated by the coolant flow rate information at the liquid cooler speed indicated by the liquid cooler speed information.

[0052] Step S203: Based on the liquid cooler speed information, control the operation of the liquid cooler of the charging device.

[0053] In the disclosed embodiment, under the above implementation, the liquid cooler speed information has at least two forms, namely, the liquid cooler speed value and the liquid cooler speed range.

[0054] When the liquid cooler speed information is the liquid cooler speed value, based on the liquid cooler speed information, the method of controlling the operation of the liquid cooler of the charging equipment can be that when the current liquid cooler speed is lower than the liquid cooler speed value, the speed of the liquid cooler is controlled to gradually increase to the liquid cooler speed value; when the current liquid cooler speed is equal to the liquid cooler speed value, the liquid cooler is controlled to maintain the current speed; when the current liquid cooler speed is higher than the liquid cooler speed value, the speed of the liquid cooler is controlled to gradually decrease to the liquid cooler speed value.

[0055] When the liquid cooler speed information is a liquid cooler speed range, based on the liquid cooler speed information, the method for controlling the operation of the liquid cooler of the charging device may be to select any liquid cooler speed value within the liquid cooler speed range as the control target, and gradually change the speed of the liquid cooler until the control target is maintained; when the liquid cooler speed information is a liquid cooler speed range, based on the liquid cooler speed information, the method for controlling the operation of the liquid cooler of the charging device may also refer to the current charging gun head temperature. When the current charging gun head temperature is high, a higher speed within the liquid cooler speed range may be selected as the control target, and the speed of the liquid cooler may be gradually changed until the control target is maintained. When the current charging gun head temperature is low, a lower speed within the liquid cooler speed range may be selected as the control target, and the speed of the liquid cooler may be gradually changed until the control target is maintained.

[0056] The present disclosure obtains temperature information corresponding to the charging gun head of the charging device and uses the temperature information as a parameter for controlling the operation of the liquid cooler, thereby using the temperature at a position where the risk of abnormal conditions occurring in the charging device is higher as an indicator for controlling the liquid cooler; by determining the liquid cooler speed information corresponding to the temperature information based on a preset temperature-speed correspondence, and controlling the operation of the liquid cooler of the charging device based on the liquid cooler speed information, the liquid cooling system of the charging device can be operated based on the temperature state of the charging gun head, thereby reducing the risk of abnormal conditions occurring in the charging gun head and improving the safety of power supply to the charging device.

[0057] Figure 4 FIG. 1 is a flow chart showing a matching relationship between a preset temperature and a flow rate according to an exemplary embodiment. In an optional embodiment, Figure 4 As shown, the method also includes: Step S401: obtaining a plurality of sample temperatures and target coolant flow rate information corresponding to each of the plurality of sample temperatures, wherein the target coolant flow rate information represents the coolant flow rate required for reducing the temperature of the charging gun head from the corresponding sample temperature to the target temperature.

[0058] In the disclosed embodiment, the multiple sample temperatures may be adjacent temperature values ​​spaced at certain intervals, such as 50 degrees, 52 degrees, 54 degrees, 56 degrees, 58 degrees, or 50 degrees, 55 degrees, 60 degrees. The target coolant flow rate information corresponding to each of the multiple sample temperatures can be obtained through a large number of tests. For example, when the temperature of the charging gun head reaches a certain sample temperature, the coolant flow rate is changed to obtain the coolant flow rate required to reduce the temperature of the charging gun head from the sample temperature to the target temperature. The above tests are performed on the above multiple sample temperatures to obtain the target coolant flow rate information corresponding to each of the multiple sample temperatures.

[0059] Step S402: performing data fitting processing on the sample temperature and the target coolant flow rate information to obtain a preset temperature-flow rate correspondence relationship.

[0060] In the disclosed embodiment, data fitting of the sample temperature and target coolant flow rate information can be performed by curve fitting based on the above-mentioned multiple sample temperatures and the target coolant flow rate information corresponding to each of the multiple sample temperatures, to obtain a curve that characterizes the coolant flow rate relationship required for the temperature of the charging gun head to be reduced from the corresponding sample temperature to the target temperature, and the curve is used as the preset temperature-flow rate correspondence. Furthermore, the expression corresponding to the curve can also be used as the preset temperature-flow rate correspondence. Furthermore, the coolant flow rate values ​​corresponding to different temperature values ​​determined by the expression can also be appropriately expanded to obtain the corresponding coolant flow rate intervals, and tabulated to obtain a statistical table of the coolant flow rate intervals corresponding to different temperature values, and the statistical table is used as the preset temperature-flow rate correspondence.

[0061] Based on the above, it can be known that the embodiment of the present disclosure obtains multiple sample temperatures and the target coolant flow rate information corresponding to each of the multiple sample temperatures, and performs data fitting processing on the sample temperatures and the target coolant flow rate information to obtain a preset temperature-flow rate correspondence. It is able to associate different temperature values ​​with the coolant flow rate required to reduce the temperature of the charging gun head from the temperature value to the target temperature, so as to quickly match the gun tip temperature and the coolant flow rate.

[0062] Figure 5 FIG. 1 is a flow chart showing a matching relationship between a preset flow rate and a rotation speed according to an exemplary embodiment. Figure 5 As shown, the method also includes: Step S501: obtaining a plurality of sample coolant flow rates and target liquid cooler speed information corresponding to each of the plurality of sample coolant flow rates, wherein the target liquid cooler speed information represents the liquid cooler speed corresponding to when the coolant in the liquid cooling system driven by the liquid cooler reaches the sample coolant flow rate.

[0063] In the embodiment of the present disclosure, the plurality of sample coolant flow rates may be a plurality of adjacent flow rate values ​​spaced at certain intervals, such as 0.1 m / s, 0.12 m / s, 0.14 m / s, 0.16 m / s, 0.18 m / s, etc., or 0.1 m / s, 0.2 m / s, 0.3 m / s, 0.4 m / s, etc. The target liquid cooler speed information corresponding to each of the plurality of sample coolant flow rates may be obtained through a large number of tests. For example, when the coolant flow rate in the liquid cooling system reaches a certain sample coolant flow rate, the liquid cooler speed at that moment is recorded to obtain the liquid cooler speed corresponding to the coolant in the liquid cooling system when the liquid cooler drives the coolant in the liquid cooling system to reach the sample coolant flow rate. The above tests are performed on the plurality of sample coolant flow rates to obtain the target liquid cooler speed information corresponding to each of the plurality of sample coolant flow rates.

[0064] Step S502: performing data fitting processing on the sample coolant flow rate and the target liquid cooler speed information to obtain a preset flow rate and speed correspondence relationship.

[0065] In the disclosed embodiment, data fitting of the sample coolant flow rate and the target liquid cooler speed information can be performed by curve fitting based on the above-mentioned multiple sample coolant flow rates and the target liquid cooler speed information corresponding to each of the multiple sample coolant flow rates, to obtain a curve representing the liquid cooler speed corresponding to the coolant in the liquid cooling system driven by the liquid cooler when the sample coolant flow rate is reached, and the curve is used as the preset flow rate and speed correspondence. Further, the expression corresponding to the curve can also be used as the preset flow rate and speed correspondence. Further, the liquid cooler speed corresponding to representative different flow rate values ​​can also be calculated by the expression, and tabulated to obtain a statistical table of the liquid cooler speed corresponding to different flow rate values, and the statistical table is used as the preset flow rate and speed correspondence.

[0066] Based on the above, the embodiment of the present disclosure obtains multiple sample coolant flow rates and the target liquid cooler speed information corresponding to each of the multiple sample coolant flow rates, and performs data fitting processing on the sample coolant flow rates and the target liquid cooler speed information to obtain a preset flow rate and speed correspondence relationship. It is able to associate different coolant flow rate values ​​with the liquid cooler speed corresponding to the coolant in the liquid cooler driven liquid cooling system when the coolant reaches the coolant flow rate value, so as to quickly match the coolant flow rate with the liquid cooler speed.

[0067] Figure 6 FIG. 1 is a flow chart showing a method of controlling a charging device to perform a power output operation according to an exemplary embodiment. In an optional embodiment, Figure 6 As shown, the method also includes: Step S601: When the temperature information is greater than or equal to the first preset temperature threshold and less than the second preset temperature threshold, determine the charging power adjustment information corresponding to the temperature information, the charging power adjustment information represents the output power value that the current charging device should reduce, and the second preset temperature threshold is greater than the first preset temperature threshold.

[0068] In the disclosed embodiment, the value of the second preset temperature threshold can be set to the upper limit alarm temperature of the liquid cooling gun, and the upper limit alarm temperature of the liquid cooling gun is higher than the temperature within the safe charging temperature range of the charging gun head. When the temperature information is greater than or equal to the first preset temperature threshold, and less than the second preset temperature threshold, it means that the liquid cooling system can no longer meet the cooling requirements of the current charging device, which means that the output power of the charging device is too large and generates too much heat. Therefore, the output power of the charging device needs to be adjusted to reduce the heat generated by the charging device as much as possible.

[0069] Determine that the charging power adjustment information corresponding to the temperature information can be adjusted according to the first preset adjustment condition, specifically including: first determine the target temperature difference, the target temperature difference refers to the temperature value when the temperature information exceeds the first preset temperature threshold, determine the ratio of the target temperature difference to the target threshold difference, the target threshold difference refers to the difference between the second preset temperature threshold and the first preset temperature threshold, multiply the output power of the charging gun head of the current charging device by the ratio to obtain the charging power adjustment information.

[0070] Determine that the charging power adjustment information corresponding to the temperature information can be adjusted according to the second preset adjustment condition, specifically including: dividing the temperature value between the first preset temperature threshold and the second preset temperature threshold into multiple preset temperature intervals according to the numerical value from small to large, each preset interval is set with a corresponding power adjustment amount, and the power adjustment amount corresponding to each preset interval is different. The power adjustment amount corresponding to different preset intervals increases with the increase of the temperature data in the interval, determine the preset temperature interval in which the temperature information is located, and determine the power adjustment amount corresponding to the preset temperature interval as the charging power adjustment information.

[0071] Step S602: Based on the charging power adjustment information, control the charging device to perform power output operation.

[0072] In the embodiment of the present disclosure, based on the charging power adjustment information, controlling the charging device to perform a power output operation can be performed by subtracting the output power of the current charging gun head from the charging power adjustment information to obtain the target output power, dividing the target output power by the output voltage of the current charging gun head to obtain the target output current, and controlling the charging gun head to maintain output at the target output current.

[0073] Based on the above, it can be known that the embodiment of the present disclosure determines the charging power adjustment information corresponding to the temperature information when the temperature information is greater than or equal to the first preset temperature threshold and less than the second preset temperature threshold, and controls the charging device to perform power output operation based on the charging power adjustment information. It can timely reduce the output power when the temperature information of the gun tip of the charging device is high, thereby preventing danger caused by continuous excessive temperature rise when the temperature is high.

In an optional embodiment, Figure 7 As shown, the method also includes: Step S701: Obtain temperature rise information corresponding to the charging gun head.

[0075] In the disclosed embodiment, the temperature rise information corresponding to the charging gun head can be obtained by subtracting two adjacent temperature sampling values ​​with a preset time interval to obtain the temperature rise information; the temperature rise information corresponding to the charging gun head can also be obtained by subtracting the previous temperature sampling value from the latter of the two adjacent temperature sampling values ​​and dividing the difference obtained by dividing the previous temperature sampling value by the previous temperature sampling value to obtain the temperature rise information.

[0076] Step S702: When the temperature rise information meets the preset alarm condition, the charging device is controlled to interrupt the charging operation.

[0077] In the embodiment of the present disclosure, the preset alarm condition may be that the value corresponding to the temperature rise information exceeds the preset value. When the value corresponding to the temperature rise information exceeds the preset value, it means that the current temperature rise is too fast, the charging circuit may fail, and the charging state can no longer be maintained. Therefore, the charging device is controlled to interrupt the charging operation to avoid greater danger. Based on the above, it can be known that the embodiment of the present disclosure controls the charging device to interrupt the charging operation when the temperature rise information corresponding to the charging gun head meets the preset alarm conditions. It can timely interrupt the power output of the charging device when the temperature rise of the gun head is too high, prevent the occurrence of danger in the charging process, and improve the safety of charging.
