[0002] With the widespread use of unmanned vehicles, the requirements for their operating efficiency and carrying capacity are constantly increasing, which has led to an increase in the power and speed indicators of unmanned vehicles, and the heat dissipation problem has also become prominent. Most unmanned vehicles still use traditional cooling methods such as natural cooling or air cooling. However, when the unmanned vehicle is in a high-power operating state, the heat dissipation efficiency of the traditional cooling method is seriously insufficient and cannot achieve rapid cooling. In addition, traditional cooling technology cannot flexibly adjust the cooling strategy according to the actual operating conditions of the unmanned vehicle, resulting in an imbalance between heat dissipation energy consumption and heat dissipation effect, causing energy waste. Therefore, providing a cooling method that can achieve efficient and rapid cooling with low cooling energy consumption has become a key technical problem that urgently needs to be solved in the field of vehicle cooling technology.

[0027] Example 1

[0028] Figure 1A flowchart of a cooling control method is provided for the first embodiment of the present invention. The embodiment of the present invention is applicable to the scenario of performing cooling operations on the cooling components under different working modes of the charger. The method can be executed by a cooling control system, which can be implemented in the form of hardware and / or software. The cooling control system can be configured in an electronic device. Figure 1 As shown, the method includes:

[0029] S110: Determine that the working mode of the charger is the charging mode, and obtain real-time temperature data of the charger and a preset step temperature threshold range.

[0030] The term "operating mode" refers to the operating state of the charger during operation. The operating mode of the charger may include charging mode or standby mode. Charging mode refers to the state in which the charger is normally charging the battery, while standby mode refers to a state in which the charger is in a low-power, standby state ready to respond to charging commands. Furthermore, in embodiments of the present invention, the battery management system may directly collect the voltage or current value of the charger, and determine whether the charger is in charging mode based on the voltage or current value. When the voltage or current value exceeds a certain threshold, the charger's operating mode may be determined to be charging mode. Alternatively, a hardware sensor may be provided at the vehicle's charging port to provide feedback on the charger's voltage or current value.

[0031] Real-time temperature data refers to the temperature value of the charger collected during charging mode, which can reflect the temperature status of the charger at a specific time during charging mode. For example, when the real-time temperature data of the charger exceeds a preset temperature value, it indicates that the charger is in an abnormal temperature state and requires cooling. Furthermore, in embodiments of the present invention, the real-time temperature data of the charger can be obtained by installing a temperature sensor on the surface or inside the charger to collect the real-time temperature data of the charger, or by using a battery management system to monitor the charger in real time.

[0032] The preset step temperature threshold interval refers to a series of pre-set temperature range intervals used to classify the real-time temperature data of the charger. The preset step temperature threshold intervals are distributed in a step-by-step manner and may include a high-level temperature threshold interval, a mid-level temperature threshold interval, and a low-level temperature threshold interval. Each temperature threshold interval corresponds to a different temperature range, and different temperature ranges can trigger different cooling strategies. For example, the temperature range of the high-level temperature threshold interval is 70°C to 100°C, and the corresponding cooling strategy is to turn on the high-speed mode of the electronic fan. The temperature range of the mid-level temperature threshold interval is 40°C to 70°C, and the corresponding cooling strategy is to turn on the low-speed mode of the electronic fan. The temperature range of the low-level temperature threshold interval is 0°C to 40°C, and the corresponding cooling strategy is to turn on the electronic water pump. It is worth noting that the temperature range intervals and cooling strategies of the above-mentioned high-level temperature threshold interval, mid-level temperature threshold interval, and low-level temperature threshold interval are merely examples to facilitate understanding that each temperature threshold interval corresponds to a different temperature range, and different temperature ranges can trigger different cooling strategies. The charger's preset temperature threshold intervals can be determined by the temperature data corresponding to the slope mutation points of the charger's temperature-power function, or based on the charger's actual cooling requirements. The pre-configured temperature threshold intervals can be stored in local memory or on a remote server.

[0033] Specifically, the voltage or current value of the charger is directly collected through the battery management system, or a hardware sensor is set at the vehicle charging interface to feedback the voltage or current value of the charger through the hardware sensor. The voltage or current value is used to determine whether the charger has entered the charging mode. When the voltage or current value is greater than a certain threshold, the working mode of the charger can be determined to be the charging mode. After determining that the working mode of the charger is the charging mode, the real-time temperature data of the charger can be collected in real time by using a temperature sensor installed on the surface or inside the charger. The real-time temperature data of the charger can also be directly obtained by real-time monitoring using the battery management system. The preset step temperature threshold interval pre-configured in the local memory or remote server is obtained by scanning the local memory or establishing a connection with the remote server. The pre-configured preset step temperature threshold interval can be stored in the local memory or remote server in the form of a configuration file or underlying resources.

[0034] S120 , determining a target step temperature threshold interval corresponding to the real-time temperature data within a preset step temperature threshold interval according to the temperature value of the real-time temperature data.

[0035] Among them, the target step temperature threshold interval refers to a temperature range interval to which the temperature value of the real-time temperature data belongs within the preset step temperature threshold interval. The target step temperature threshold interval can accurately reflect the temperature range of the charger at a specific time and is used for the selection of subsequent cooling strategies.

[0036] Specifically, a temperature value of the charger's real-time temperature data is obtained and compared with the boundaries of each temperature range in a preset stepped temperature threshold interval until the temperature range to which the temperature value belongs is found within the preset stepped temperature threshold interval. This temperature range is then used as the target stepped temperature threshold interval for subsequent cooling strategy selection. Furthermore, in embodiments of the present invention, the target stepped temperature threshold interval to which the temperature value belongs can be determined using a binary search algorithm or a fuzzy logic algorithm. Alternatively, the target temperature threshold interval can be determined by subtracting the temperature value from the lower temperature boundary of the preset stepped temperature threshold interval to obtain a threshold difference. The preset cooling temperature threshold interval corresponding to the minimum non-negative threshold difference is then used as the target temperature threshold interval.

[0037] S130 , acquiring a target cooling strategy associated with the target step temperature threshold interval from a preset strategy library based on the target step temperature threshold interval; the target cooling strategy at least includes an electronic water pump control strategy and an electronic fan control strategy.

[0038] Among them, the preset strategy library is a pre-established database or strategy set for storing various cooling strategies. The cooling strategies can be stored in the preset strategy library in the form of data tables or data packets. Each cooling strategy in the preset strategy library corresponds to a specific target step temperature threshold interval, which can be used to guide the charger to adopt an applicable cooling strategy within different temperature ranges. The preset strategy library includes at least an electronic water pump control strategy and an electronic fan control strategy. Among them, the electronic water pump control strategy refers to controlling the operating state of the electronic water pump by adjusting the speed or start-stop time of the electronic water pump to achieve a cooling effect. The electronic fan control strategy refers to controlling the operating state of the electronic fan by adjusting the speed or start-stop time of the electronic fan to achieve a cooling effect.

[0039] Specifically, the target step temperature threshold interval to which the real-time temperature data of the charger belongs and a pre-configured preset strategy library are obtained. The preset strategy library includes at least an electronic water pump control strategy and an electronic fan control strategy. Based on the correspondence between the target step temperature threshold interval and each cooling strategy in the preset strategy library, the target step temperature threshold interval is used as an index to search the preset strategy library for the target cooling strategy associated with the target step temperature threshold interval through hash search or matching traversal. The target cooling strategy can be the electronic water pump control strategy in the preset strategy library or the electronic fan control strategy in the preset strategy library. It is worth noting that by executing the target cooling strategy, all components to be cooled in the cooling circuit can be cooled, wherein the components to be cooled include at least the charger, which can be connected in series with other components to be cooled. The cooling circuit can refer to a circuit consisting of the charger, other components to be cooled, an electronic water pump, an electronic fan, and a radiator.

[0040] In an embodiment of the present invention, the operating mode of the charger is determined to be in charging mode, and the real-time temperature data and preset step temperature threshold intervals of the charger are obtained. The target step temperature threshold interval corresponding to the real-time temperature data is determined within the preset step temperature threshold interval according to the temperature value of the obtained real-time temperature data. Based on the determined target step temperature threshold interval, the target cooling strategy associated with the target step temperature threshold interval is obtained from the preset strategy library. By identifying the charging state of the charger, the embodiment of the present invention can accurately deploy the target cooling strategy, solving the energy waste problem caused by excessive heat dissipation in traditional methods and effectively reducing cooling energy consumption. The stepped temperature threshold intervals enable rapid matching of cooling strategies, thereby improving cooling efficiency.

[0041] Furthermore, a cooling control method provided by an embodiment of the present invention also includes: determining that the working mode of the charger is a non-charging mode, obtaining the first real-time temperature data of the charger and the second real-time temperature data of the all-in-one controller; obtaining the first preset step temperature threshold interval of the charger and the second preset step temperature threshold interval of the all-in-one controller; determining the first target step temperature threshold interval corresponding to the first real-time temperature data within the first preset step temperature threshold interval according to the temperature value of the first real-time temperature data; determining the second target step temperature threshold interval corresponding to the second real-time temperature data within the second preset step temperature threshold interval according to the temperature value of the second real-time temperature data; comparing the orders of the first target step temperature threshold interval and the second target step temperature threshold interval, and using the first target step temperature threshold interval or the second target step temperature threshold interval with the higher order as the target step temperature threshold interval of the charger in the non-charging mode, and the orders include at least high order, medium order and low order.

[0042] The first real-time temperature data refers to the temperature value of the charger collected at a specific time in non-charging mode, reflecting the temperature status of the charger at that specific time. The second real-time temperature data refers to the temperature value of the all-in-one controller collected at a specific time in non-charging mode, reflecting the temperature status of the all-in-one controller at that specific time. The first real-time temperature data and the second real-time temperature data have the same time stamp.

[0043] The first preset step temperature threshold interval refers to a temperature range interval used to classify the first real-time temperature data of the charger, and the second preset step temperature threshold interval refers to a temperature range interval used to classify the second real-time temperature data of the charger. Similar to the preset step temperature threshold intervals, the first and second preset step temperature threshold intervals may also include a high-level temperature threshold interval, a mid-level temperature threshold interval, and a low-level temperature threshold interval. Each temperature threshold interval also corresponds to a different temperature range, and different temperature ranges may trigger different cooling strategies.

[0044] The order can be understood as a quantitative indicator for dividing the temperature threshold interval levels. The order may include high order, medium order and low order, which is used to measure the high and low temperature values ​​within the temperature threshold interval. The temperature values ​​in temperature threshold intervals of different orders are different. For example, the temperature value in the high-order temperature threshold interval is higher than the temperature value in the low-order temperature threshold interval.

[0045] Specifically, the voltage or current value of the charger is directly collected through the battery management system, or a hardware sensor is set at the vehicle charging interface to feed back the voltage or current value of the charger through the hardware sensor. Whether the charger enters the charging mode is determined by the size of the voltage or current value. When the voltage or current value is less than a certain threshold, it can be determined that the working mode of the charger is the non-charging mode. After determining that the charging state of the charger is the non-charging mode, the real-time temperature data of the charger at a non-specific time and the real-time temperature data of the multi-in-one controller at the same specific time are obtained. The real-time temperature data of the charger at a specific time in the non-charging mode is used as the first real-time temperature data, and the real-time temperature data of the multi-in-one controller at the same specific time is used as the first real-time temperature data; the pre-configured temperature data for the charger in the local memory or remote server is obtained by scanning the local memory or establishing a connection with the remote server. The configured first preset step temperature threshold interval and the pre-configured second preset step temperature threshold interval for the all-in-one controller, the pre-configured first preset step temperature threshold interval and the second preset step temperature threshold interval can be stored in the local memory or remote server in the form of a configuration file or underlying resources, obtain the order of the first preset step temperature threshold interval and the second preset step temperature threshold interval, use the order of the first preset step temperature threshold interval as the first order, and use the order of the second preset step temperature threshold interval as the second order, compare the first order with the second order, if the first order is higher than the second order, then use the first preset step temperature threshold interval corresponding to the first order as the target step temperature threshold interval of the charger in non-charging mode, if the second order is higher than the first order, then use the second preset step temperature threshold interval corresponding to the second order as the target step temperature threshold interval of the charger in non-charging mode.

[0046] By selecting a higher-order temperature threshold interval as the target temperature threshold interval, it is ensured that the target cooling operation can still be accurately matched in the scenario of multi-component collaborative work, thereby enhancing the reliability of the cooling control method.

[0047] Furthermore, a cooling control method provided by an embodiment of the present invention also includes: obtaining a preset temperature jump threshold, determining that the temperature drop amplitude of the temperature value of the real-time temperature data is greater than the preset temperature jump threshold, and then calling back the target cooling strategy of the charger.

[0048] The preset temperature jump threshold can be understood as a critical value used to measure the magnitude of temperature changes. The preset temperature jump thresholds for different system components vary. For example, due to the small thermal hysteresis of the all-in-one controller, the jump threshold temperature of the all-in-one controller can be set to 3°C. Due to the large thermal hysteresis of the charger, the jump threshold temperature of the charger can be set to Tc = 5°C. It is worth noting that the above jump threshold temperature values ​​are only for example purposes. In actual operation, the jump threshold temperature values ​​can be dynamically adjusted.

[0049] Specifically, a preset temperature jump threshold and a target cooling strategy for measuring the temperature change amplitude are obtained, and the charger is cooled according to the target cooling strategy. Within a specified time interval, the temperature value of the latest real-time temperature data of the charger and the initial real-time temperature data are obtained, and the temperature value of the latest real-time temperature data is subtracted from the temperature value of the initial real-time temperature data to obtain a cooling amplitude, and the cooling amplitude is compared with the preset temperature jump threshold. If the cooling amplitude is greater than the preset temperature jump threshold, it indicates that the temperature of the component to be cooled has dropped, and the target cooling strategy can be adjusted to a target cooling strategy corresponding to a lower-order temperature threshold interval.

[0050] In an embodiment of the present invention, a preset temperature jump threshold corresponding to each component to be cooled can be set according to the characteristics of the component to be cooled. When the cooling amplitude is greater than the preset temperature jump threshold, the target cooling strategy is adjusted, which can avoid frequent switching of the target cooling strategy and thus reduce cooling energy consumption.

[0051] Example 2

[0052] Figure 2 A flowchart of another cooling control method is provided for the second embodiment of the present invention. The embodiment of the present invention refines the above embodiment, specifically, refines the specific steps of how to determine the charging mode and how to determine the target cooling temperature threshold range.

[0053] like Figure 2 As shown, another cooling control method may include the following specific steps:

[0054] S210: Acquire power data of the charger and a preset charging power threshold, determine that a power value of the power data is greater than the preset charging power threshold, and determine the working mode of the charger as the charging mode.

[0055] The preset charging power threshold refers to a pre-set power critical value used to determine whether the charger is in a charging mode. When the power data of the charger exceeds the preset charging power threshold, it can be considered that the charger is performing a charging operation.

[0056] Specifically, power data of the charger is obtained, and a specific power value represented by the power data is compared with a preset charging power threshold. If the power value is greater than the preset charging power threshold, it is considered that the working mode of the charger is the charging mode.

[0057] Furthermore, in an embodiment of the present invention, it is also possible to determine whether the charger is in the charging mode by obtaining current data or voltage data of the charger. For example, in the charging mode, the charging current or charging voltage exceeds a preset threshold.

[0058] S220 , obtaining the temperature value of the real-time temperature data and all temperature lower limit thresholds of the preset step temperature threshold range corresponding to the real-time temperature data.

[0059] Among them, the temperature lower limit threshold refers to the minimum temperature value of each temperature range interval within the preset step temperature threshold interval, which is used to define the starting boundary of the temperature range interval. The temperature lower limit threshold may include a high temperature lower limit threshold and a low temperature lower limit threshold. The high temperature lower limit threshold refers to the minimum temperature value within the high-order temperature range interval, and the low temperature lower limit threshold refers to the minimum temperature value within the middle-order temperature range interval. The preset step temperature threshold interval can be divided into three step temperature threshold intervals by the high temperature lower limit threshold and the low temperature lower limit threshold. For example, the temperature interval greater than or equal to the high temperature lower limit threshold is used as the first temperature threshold interval, the temperature interval less than the high temperature lower limit threshold and greater than the low temperature lower limit threshold is used as the second temperature threshold interval; and the temperature interval less than or equal to the low temperature lower limit threshold is used as the third temperature threshold interval. It can be understood that the number of step temperature threshold intervals can be equal to the number of temperature lower limit thresholds + 1.

[0060] Specifically, the real-time temperature data of the charger and the preset step temperature threshold interval corresponding to the real-time temperature data are obtained, the temperature value of the real-time temperature data is determined, and the minimum temperature value of each temperature range interval within the preset step temperature threshold interval is extracted, and the minimum temperature value is used as the lower temperature threshold.

[0061] S230 , subtracting the temperature value from all the lower temperature thresholds respectively to obtain the threshold difference corresponding to each lower temperature threshold.

[0062] Among them, the threshold difference refers to the difference between the temperature value and different temperature lower limit thresholds, which is used to measure the relative size of the current temperature value and each temperature lower limit threshold. The threshold difference may include a negative threshold difference and a non-negative threshold difference.

[0063] Specifically, the temperature value of the real-time temperature data and all temperature lower limit thresholds of the preset step temperature threshold interval are obtained, and the temperature value is subtracted from each temperature lower limit threshold to obtain all threshold differences corresponding to all temperature lower limit thresholds.

[0064] S240 . Among the threshold differences, use the lower temperature threshold corresponding to the minimum non-negative threshold difference as the target lower temperature threshold of the target cooling temperature threshold interval.

[0065] The minimum non-negative threshold difference refers to the threshold difference with the smallest value and not less than zero among the threshold differences. The minimum non-negative threshold difference can indicate that the temperature value of the real-time temperature data is closest to the corresponding lower temperature threshold.

[0066] Specifically, the threshold difference corresponding to each temperature lower limit threshold includes a negative threshold difference and a non-negative threshold difference. The non-negative threshold difference is searched among all threshold differences. The smallest non-negative threshold difference among all threshold differences is used as the target threshold difference. The temperature lower limit threshold corresponding to the target threshold difference is used as the target temperature lower limit threshold. The preset step temperature threshold interval to which the target temperature lower limit threshold belongs is used as the target temperature lower limit threshold.

[0067] S250 : Acquire a target cooling strategy associated with the target step temperature threshold interval in a preset strategy library based on the target step temperature threshold interval.

[0068] In an embodiment of the present invention, power data and a preset charging power threshold are obtained from a charger. A determination is made that the power value of the power data is greater than the preset charging power threshold, and the charger's operating mode is determined to be charging mode. In charging mode, the temperature value of real-time temperature data and all lower temperature thresholds of preset step temperature threshold intervals corresponding to the real-time temperature data are obtained. The temperature value is subtracted from all lower temperature thresholds to obtain threshold differences corresponding to each lower temperature threshold. Among the threshold differences, the lower temperature threshold corresponding to the minimum non-negative threshold difference is used as the target lower temperature threshold of the target cooling temperature threshold interval. Based on the target step temperature threshold interval, a target cooling strategy associated with the target step temperature threshold interval is obtained from a preset strategy library. By comparing the real-time temperature data with the preset lower temperature threshold, the embodiment of the present invention accurately determines the target step temperature threshold interval to which the current real-time temperature data belongs, thereby improving the accuracy of target step temperature threshold interval temperature identification. The preset step temperature threshold interval closest to the real-time temperature is selected as the target cooling temperature interval, ensuring accurate implementation of the cooling strategy, highly adapting the cooling operation to the current temperature conditions, and enhancing the reliability of the cooling control method.

[0069] Furthermore, in an embodiment of the present invention, the following steps may be included before executing step S210: obtaining historical temperature data of the charger and historical power data corresponding to the historical temperature data; using a preset mathematical fitting tool to fit the historical temperature data and historical power data to obtain a temperature-power mapping function of the charger; determining a slope mutation point where the function slope of the temperature-power mapping function changes, and using the temperature value of the historical temperature data corresponding to the slope mutation point as the lower temperature threshold of the preset step temperature threshold interval, and the lower temperature threshold includes at least a high temperature lower limit threshold and a low temperature lower limit threshold; using a temperature interval greater than or equal to the high temperature lower limit threshold as a high-order temperature threshold interval of the preset step temperature threshold interval; using a temperature interval less than the high temperature lower limit threshold and greater than the low temperature lower limit threshold as a mid-order temperature threshold interval of the preset step temperature threshold interval; and using a temperature interval less than or equal to the low temperature lower limit threshold as a low-order temperature threshold interval of the preset step temperature threshold interval.

[0070] The preset mathematical fitting tool may be understood as a software tool or algorithm for establishing a mathematical relationship between historical temperature data and historical power data. For example, the preset mathematical fitting tool may include Matlab or a linear regression algorithm.

[0071] The temperature-power mapping function is a mathematical function derived by fitting the charger's historical temperature and power data. This function represents the relationship between charger temperature and power. This function provides an intuitive understanding of the charger's temperature trends at different power levels.

[0072] The slope mutation point refers to the point where the function slope of the temperature power mapping function changes significantly. It can be used as a key node for dividing the preset step temperature threshold interval and used to determine the boundaries of different temperature ranges within the preset step temperature threshold interval.

[0073] Specifically, historical temperature data of the charger between specific time periods and historical power data corresponding to the historical temperature data are obtained, the historical temperature data and the historical power data having the same time stamp, a preset mathematical fitting tool such as Matlab or a linear regression algorithm is called, the historical temperature data and the historical power data are input into the preset mathematical fitting tool, the preset mathematical fitting tool fits the historical temperature data and the historical power data, outputs a temperature-power mapping function of the charger and a slope mutation point where the function slope of the temperature-power mapping function changes, the lower temperature value of the historical temperature data corresponding to the slope mutation point is taken as the low temperature lower limit threshold value of the preset step temperature threshold interval, the higher temperature value of the historical temperature data corresponding to the slope mutation point is taken as the high temperature lower limit threshold value of the preset step temperature threshold interval, the temperature interval greater than or equal to the high temperature lower limit threshold is taken as the high-order temperature threshold interval of the preset step temperature threshold interval, the temperature interval less than the high temperature lower limit threshold and greater than the low temperature lower limit threshold is taken as the middle-order temperature threshold interval of the preset step temperature threshold interval, and the temperature interval less than or equal to the low temperature lower limit threshold is taken as the low-order temperature threshold interval of the preset step temperature threshold interval.

[0074] By determining the slope mutation point through the temperature-power mapping function and determining the preset step temperature threshold range based on the slope mutation point, the target cooling strategy setting can be more closely aligned with the actual working state of the equipment, thereby achieving accurate and rapid cooling effects.

[0075] Furthermore, in an embodiment of the present invention, the steps of how to obtain a target cooling strategy associated with a target step temperature threshold interval in a preset strategy library based on the target step temperature threshold interval are refined. Specifically, the steps may include: when the target cooling temperature threshold interval is a high-order temperature threshold interval within the preset step temperature threshold interval, searching the electronic fan high-speed mode strategy in the electronic fan control strategy as the target cooling strategy; when the target cooling temperature threshold interval is a mid-order temperature threshold interval within the preset step temperature threshold interval, searching the electronic fan low-speed mode strategy in the electronic fan control strategy as the target cooling strategy; when the target cooling temperature threshold interval is a low-order temperature threshold interval within the preset step temperature threshold interval, searching the electronic water pump start-up strategy in the electronic water pump control strategy as the target cooling strategy.

[0076] Specifically, a target cooling temperature threshold interval is obtained for the real-time temperature data of the charger within a preset cooling temperature threshold interval. The target cooling temperature threshold interval can be a high-order temperature threshold interval, a mid-order temperature threshold interval, or a low-order temperature threshold interval. When the target cooling temperature threshold interval is a high-order temperature threshold interval, the electronic fan high-speed mode strategy is searched within the electronic fan control strategy as the target cooling strategy; when the target cooling temperature threshold interval is a mid-order temperature threshold interval, the electronic fan low-speed mode strategy is searched within the electronic fan control strategy as the target cooling strategy; and when the target cooling temperature threshold interval is a low-order temperature threshold interval, the electronic water pump start strategy is searched within the electronic water pump control strategy as the target cooling strategy. Furthermore, in an embodiment of the present invention, a strategy for extending the operating time of the electronic fan or electronic water pump can also be used as the target cooling strategy.

[0077] By setting the corresponding target cooling strategy according to the order of the target cooling temperature threshold interval, it is possible to ensure that the most suitable cooling strategy is quickly activated in different temperature ranges, thereby achieving the cooling efficiency of the cooling control method.

[0090] Example 4

[0091] Figure 4 This is a schematic diagram of another cooling control system provided by the fourth embodiment of the present invention. This embodiment is applicable to the case where a vehicle cools down components to be cooled in different driving states. The system can be implemented in software and / or hardware and can be integrated into any device that provides cooling control functions, such as Figure 4As shown, another cooling control system specifically includes: a battery management system, a vehicle controller and a cooling circuit, wherein the cooling circuit includes a radiator, an electronic fan, an electronic water pump, an electric drive, an all-in-one controller and an expansion tank; the battery management system and the vehicle controller are both communicatively connected to the cooling circuit, and the radiator is connected to the electronic fan; the radiator, the electronic water pump and the components to be cooled are connected in a circular manner via water pipes; the expansion tank is connected to the radiator water inlet pipe and the radiator water outlet pipe of the radiator via a breathable pipe and a tee, respectively. A cooling control system provided by an embodiment of the present invention can cool the components to be cooled in an unmanned vehicle, such as the electric drive and the all-in-one controller, and specifically includes the following process: after the high-voltage system of the vehicle is successfully powered on, the electronic water pump is started, and the first-level cooling mode is started, that is, the coolant in the radiator is sucked into the water pump, and after being pressurized, it flows into the components that need to dissipate heat (for example, the electric drive and the all-in-one controller). After the coolant absorbs heat, the temperature rises and then flows to the radiator. The function of the expansion kettle is to: as the coolant temperature rises, its volume expands, causing some coolant to flow from the main circulation piping into the expansion kettle, preventing excessive pressure within the system from causing pipe ruptures. After shutdown, the coolant temperature drops and its volume contracts, causing the coolant in the expansion kettle to flow back into the main circulation via a siphon effect, preventing a vacuum in the piping. The expansion kettle also removes air that has entered the coolant circulation through the exhaust port, preventing air from obstructing the coolant flow.

[0092] The electric drive and the all-in-one controller can feed back their own temperatures to the vehicle controller. After receiving the temperature data fed back by the electric drive and the all-in-one controller, the vehicle controller makes a judgment on it. The battery management system can be used to identify the operating mode of the charger. It is worth noting that when the charger is in non-charging mode, it can indicate that the vehicle where the charger is located is in the driving process. The operating mode is sent to the vehicle controller. After receiving the non-charging operating mode, the vehicle controller will obtain the temperature of the multi-in-one controller and the electric drive temperature. If the temperature of the three-in-one controller is ≥45°C or the temperature of the electric drive is ≥60°C, the second-level cooling mode is activated, that is, a pulse signal is sent to the electronic fan to turn on the low-speed mode. If the temperature of the three-in-one controller is ≥60°C or the temperature of the electric drive is ≥90°C, the third-level cooling mode is activated, that is, a pulse signal is sent to the electronic fan again to turn on the high-speed mode. Among them, the multi-in-one controller may include an on-board charger, a DC converter and / or a distribution box, and the electric drive may include an electronic control and / or a motor. The temperature of the three-in-one controller ≥45°C means that the temperature of any component of the on-board charger, DC converter or distribution box is ≥45°C, and the temperature of the electric drive ≥60°C means that the temperature of any component of the electronic control or motor is ≥60°C.

[0093] If the charger is in charging mode (which indicates the vehicle is not in motion), the following cooling strategy will be implemented: If the charger temperature is ≥45°C, the electronic fan will be activated in low speed mode; if the charger temperature is ≥55°C, the electronic fan will be activated in high speed mode. This cooling strategy in charging mode ensures that the charger's charging power is no less than 6.6 kW. This strategy allows the charger to operate at full power, balancing charging speed and heat dissipation.

[0094] Furthermore, in an embodiment of the present invention, the cooling mode can be dynamically adjusted as the temperature rises and falls. That is, if the cooling effect temperature is lower than the jump threshold temperature, the system will revert to the previous mode. Furthermore, due to the different operating characteristics and thermal characteristics of the on-board charger, DC converter, distribution box, electronic control, and motor, the jump threshold temperatures also differ. For example, due to the large motor hysteresis, the motor jump threshold temperature can be set to 8°C; the DC converter has a small thermal hysteresis, so the DC converter jump threshold temperature can be set to 3°C; the charger has a general thermal hysteresis and is only activated in charging mode, so the charger jump threshold temperature can be set to Tc = 5°C. By differentiating the jump threshold temperatures for different components, frequent switching of cooling modes can be avoided, reducing cooling energy consumption.

[0095] Furthermore, in an embodiment of the present invention, when the temperature of the component to be cooled reaches a certain threshold value while the unmanned vehicle is driving, the electronic water pump and the electronic fan are turned on at the same time to quickly cool the component to be cooled in the unmanned vehicle. At this time, if the unmanned vehicle immediately enters the charging mode when it stops driving, the electronic fan can be turned off first. When the temperature of the charger reaches a certain threshold value, the electronic fan is turned on for cooling to achieve the purpose of reducing cooling energy consumption.
