[0002] With the development of electric vehicle technology, extended-range vehicles are gaining more and more attention as a solution that combines the advantages of electric drive and traditional internal combustion engines. This type of vehicle charges the battery through a built-in range extender (an auxiliary engine), which increases the vehicle's range. In order to adapt to various application scenarios of the vehicle, current extended-range vehicles usually have multiple types of modes, including vehicle mode, scenario mode, vehicle main mode, driving mode, etc. Users can switch between different modes according to different application scenarios.

[0037] In order to solve the technical problems that the thermal management control of the prior art has poor adaptability to scenarios and is prone to insufficient thermal management power, battery power loss and other technical problems, the present application provides a vehicle thermal management control method, which can combine the thermal management control strategy with the vehicle's operating mode to improve the scenario adaptability of thermal management control and avoid problems such as insufficient thermal management power and battery power loss.

[0038] Figure 1 A flow chart of a vehicle thermal management control method provided in an embodiment of the present application. The method can be applied to a vehicle and is usually executed by a controller on the vehicle, which can be connected to a thermal management controller on the vehicle and send a control signal to the thermal management controller. The method can also be executed by one or more electronic devices such as a server, a smart phone, and a laptop computer, which are connected to the vehicle in communication, and after executing the method, a control signal for controlling the thermal management system is sent to the vehicle.

[0039] In addition, the execution subject of the present method may be hardware or software. When the execution subject is hardware, the execution subject may be one or more of the electronic devices. For example, a single electronic device may execute the present method, or a plurality of electronic devices may cooperate with each other to execute the present method. When the execution subject is software, the present method may be implemented as a plurality of software or software modules, or as a single software or software module. No specific limitation is made herein.

[0040] like Figure 1 As shown, the method specifically includes:

[0041] Step 101, determining at least one current operating mode of the target vehicle.

[0042] In some embodiments, the target vehicle is the vehicle targeted by the method, and the vehicle may be various types of vehicles, for example, an extended-range vehicle. The working mode of the vehicle may be preset, and different working modes may correspond to different application scenarios.

[0043] The at least one working mode mentioned above may correspond to different working mode categories, for example, the working mode categories may include scenario mode categories, vehicle mode categories, energy mode categories, driving mode categories, etc. Among them, the scenario mode categories may include interior display vehicle mode, exterior display vehicle mode, camping mode, sleeping mode, etc.; the vehicle mode categories may include conventional control mode, remote interaction mode, DC charging mode, AC charging mode, etc.; the energy mode categories may include pure electric priority mode, fuel priority mode, automatic mode; the driving mode categories may include economic mode, comfort mode, sports mode, etc.

[0044] Step 102: Determine a target operating mode that meets a preset thermal management high-power operating start condition from at least one operating mode.

[0045] In some embodiments, the high-power operation start condition of thermal management is a prerequisite for the operation of the high-power drive device included in the thermal management system for driving the target vehicle. The above-mentioned thermal management system is a system for adjusting the temperature of various areas that need temperature control on the target vehicle. Generally, the thermal management system includes a motor electronic control system, a battery system, a passenger compartment air conditioning system, etc. The above-mentioned high-power drive device is a device in the thermal management system that needs to be driven by a higher power, that is, a device that exceeds a preset power threshold, such as an air conditioner, a fan, etc. The preset power threshold can be set in advance according to the power consumption of each device included in the thermal management system. For example, the power consumption of each device within a certain period of time can be counted, and the proportion of each device in the total power consumption of the thermal management system can be determined. According to the set lower limit of the proportion, the corresponding power is calculated as the preset power threshold. The device whose power exceeds the preset power threshold needs to obtain more electrical energy from the battery, and it is necessary to limit the power upper limit of the thermal management system when the device is running. The high-power operation start condition of thermal management is related to the current state of the vehicle in at least one of the above working modes. For different working modes, corresponding thermal management high-power working start conditions can be set. When the vehicle state in one or more working modes matches the vehicle state specified by the corresponding thermal management high-power working start conditions, the one or more working modes can be determined as the target working mode.

[0046] For example, if at least one of the above working modes includes a camping mode, that is, the user selects and starts the camping mode when using the target vehicle as a camper, if the remaining fuel level of the vehicle is greater than zero, it is determined that the thermal management high-power working start-up conditions are met, and the camping mode is determined as the target working mode. For another example, if at least one of the above working modes includes a remote interaction mode, that is, the user interacts with the vehicle remotely through a mobile phone or other device, if the remaining battery power is greater than 20%, it is determined that the thermal management high-power working start-up conditions are met, and the remote interaction mode is determined as the target working mode.

[0047] Step 103: determine a thermal management power limit corresponding to the target operating mode.

[0048] In some embodiments, the correspondence between the thermal management power limit and the target operating mode can be preset. For example, a fixed thermal management power limit corresponding to each operating mode can be set, or a thermal management power limit calculation formula corresponding to each operating mode can be set, and the vehicle state parameters under the target operating mode are calculated using the formula to obtain the thermal management power limit.

[0049] Step 104 : Generate a signal to allow the high-power driving device to operate, and limit the operating power of the thermal management system to not exceed the thermal management power limit.

[0050] In some embodiments, after determining the thermal management power limit, the electronic device executing the method may send the thermal management power limit to the thermal management controller on the target vehicle, and generate a signal allowing the high-power drive device to operate. If the current high-power drive device is not operating, the electronic device may send a thermal management high-power start signal to the thermal management system after detecting the signal, and the thermal management controller may control the high-power drive device included in the thermal management system to adjust the internal temperature of the vehicle. During the operation of the high-power drive device of the thermal management system, the thermal management controller may adjust the overall operating current, operating voltage and other parameters of the thermal management system so that the power of the thermal management system as a whole does not exceed the above-mentioned thermal management power limit, thereby ensuring the power supply stability and safety of the target vehicle. If the current high-power drive device is operating, the electronic device may keep the operating state of the high-power drive device unchanged after detecting the signal allowing the high-power drive device to operate.

[0051] The vehicle thermal management control method provided in the embodiment of the present application determines at least one current operating mode of the target vehicle, determines the target operating mode that meets the thermal management high-power operating start conditions from at least one operating mode, then determines the thermal management power limit corresponding to the target operating mode, and finally generates a signal allowing the high-power drive device to operate, and operates the thermal management system according to the thermal management power limit. The embodiment of the present application realizes the combination of the control strategy of the thermal management system with the operating mode of the vehicle, so that the thermal management system can perform adaptive control for different operating modes, thereby helping to avoid problems such as insufficient thermal management power and vehicle power loss, and improving the energy utilization efficiency and scene adaptability of thermal management operation.

[0052] In some optional implementations, such as Figure 2 As shown, step 102 includes:

[0053] Step 1021: Determine the working mode category to which each working mode in at least one working mode belongs.

[0054] Among them, at least one of the above-mentioned working modes can correspond to different working mode categories respectively. For example, the working mode category can include scenario mode category, vehicle mode category, energy mode category, driving mode category, etc.

[0055] Step 1022: Based on the order of thermal management priorities of each operating mode category, determine from at least one operating mode whether the operating mode with the highest thermal management priority meets the corresponding thermal management high-power operating start condition.

[0056] Usually, different working mode categories correspond to different thermal management priorities. For example, the working mode categories are arranged in descending order of thermal management priority as follows: scenario mode category, vehicle mode category, energy mode category & driving mode category. Among them, energy mode category & driving mode category means that the thermal management priority of these two mode categories is the same. According to the thermal management priority of the working mode category to which each working mode belongs, the working mode with the highest thermal management priority can be determined, and then the thermal management high-power working start condition corresponding to the working mode is obtained to determine whether the state of the target vehicle in the working mode meets the thermal management high-power working start condition.

[0057] Step 1023: If the operating mode with the highest thermal management priority meets the corresponding thermal management high-power operating start condition, determine the operating mode with the highest thermal management priority as the target operating mode.

[0058] As an example, if the working mode with the highest priority of thermal management is the camping mode under the scenario mode category, the corresponding thermal management high-power working start condition is: the remaining fuel is greater than zero. If the remaining fuel in the fuel tank of the current target vehicle is greater than zero, the camping mode is determined to be the target working mode. That is, in the camping mode, the range extender can be started to generate electricity, so that the vehicle has the ability to maintain power and prevent battery depletion, and the thermal management system can be started at this time.

[0059] It should be noted that if the operating mode with the highest thermal management priority does not meet the corresponding thermal management high-power operating start condition, it is determined that there is currently no target operating mode that meets the thermal management high-power operating start condition.

[0060] As an example, if the current working mode with the highest priority for thermal management is the camping mode mentioned above, but the current remaining fuel volume is zero, it is determined that the current high-power working start conditions for thermal management are not met, that is, there is no target working mode. For another example, if the current working mode with the highest priority for thermal management is the indoor exhibition vehicle mode under the scenario mode category (the vehicle is parked indoors), it is determined that the high-power working start conditions for thermal management are not met, that is, the indoor environment does not support turning on the range extender and cannot maintain the battery power, and there is no target working mode at this time.

[0061] This embodiment sets the thermal management priority of the working mode to prioritize the working modes with high thermal management priority to determine the thermal management high-power working start conditions, avoid conflicts in starting thermal management between different working modes, and improve the accuracy of the timing and scenarios for starting the thermal management system.

[0062] In some optional implementations, such as Figure 3 As shown, step 103 includes:

[0063] Step 1031 , determining the available base power of the battery of the target vehicle and the power generation power of the range extender of the target vehicle.

[0064] The available basic power is the maximum power that the battery can provide excluding the necessary power consumption. For example, the total power currently consumed by each electrical device can be collected, and then the available discharge power of the battery minus the total power consumed can be used to obtain the available basic power.

[0065] The power generation power of the range extender of the target vehicle can be obtained by collecting the range extender bus current I GCU , bus voltage U GCU Calculated, that is, the power generation power P GCU =I GCU *U GCU / 1000. Among them, I GCU The unit is A, U GCU The unit is V, then P GCU The unit is kW.

[0066] It should be noted that in some working modes, it is necessary to prohibit the range extender from starting (for example, in sleep mode, in order to ensure the safety of passengers, the range extender is prohibited from starting), so the power generation power at this time is 0.

[0067] Step 1032: Calculate the available basic power and the generated power according to the preset thermal management power control strategy corresponding to the target working mode to obtain the thermal management power limit.

[0068] Among them, the thermal management power control strategy can be preset, and the parameters of the control strategy are related to the state of the target vehicle in the target working mode.

[0069] For example, the state parameters such as the remaining power of the target vehicle and the temperature inside the target vehicle may have a corresponding relationship with the parameters of the thermal management power control strategy, and the corresponding relationship may be expressed in the form of a table, a calculation formula, etc. Through the corresponding relationship, the parameters of the thermal management power control strategy corresponding to the current state parameters of the target vehicle may be determined.

[0070] As an example, the thermal management power control strategy is shown in equation (1):

[0071] P h =Min[a*(P b +b*P GCU ), 15kW] (1)

[0072] Among them, p h Represents thermal management power, P b Indicates the available base power, P GCU Indicates the power generation, 15kW indicates the upper limit power setting, which can be set arbitrarily according to demand, Min[] indicates that the items in the brackets take the minimum value, and a and b are the parameters of the thermal management control strategy.

[0073] After obtaining the parameters a, b, available base power and power generation power, the thermal management power limit can be calculated using formula (1).

[0074] By setting the thermal management power control strategy, this embodiment can achieve accurate calculation of the thermal management power limit for the target operating mode, so that the operation of the thermal management system can be accurately matched with the target operating mode, thereby improving the scenario adaptability of the thermal management system operation.

[0075] In some optional implementations, such as Figure 4 As shown, step 1031 includes:

[0076] Step 10311, determine the available discharge power of the battery and the voltage conversion power of the target vehicle.

[0077] The available discharge power of the battery can be calculated by collecting the voltage and current at the output end of the battery. The voltage conversion power can be calculated by collecting the output voltage and current of the voltage conversion device (DC-DC device) on the vehicle. The above-mentioned voltage conversion device is used to convert the DC voltage output by the battery to obtain the voltage required by each electrical device on the vehicle.

[0078] Step 10312, subtract the voltage conversion power from the available discharge power to obtain the available basic power.

[0079] Specifically, the formula for calculating the available basic power is shown in the following formula (2):

[0080] P b =P BMSMAX -P DCDC (2)

[0081] Among them, P BMSMAX is the available discharge power, P DCDC Converts voltage to power.

[0082] This embodiment calculates the available discharge power and voltage conversion power of the battery to obtain the available basic power, which can accurately determine the power currently available for the target vehicle to support the operation of the thermal management system, and thus provide electrical energy to the thermal management system based on actual scenarios.

[0083] In some optional implementations, such as Figure 5 As shown, step 1032 includes:

[0084] Step 10321, determine the remaining battery power.

[0085] Usually, the remaining power can be represented by the acquired SOC (State of Charge) value, that is, the percentage of the remaining power to the total power.

[0086] Step 10322, obtaining the target temperature set for the thermal management system and the actual temperature at a preset position on the target vehicle, and calculating the temperature difference between the target temperature and the actual temperature.

[0087] The target temperature is the desired temperature in the car set by the user, and the preset position can be set arbitrarily, usually, it can be the position of the seat near the head of the passenger in the car. For example, the temperature T1 near the head of the front seat and the temperature T2 near the head of the rear seat can be obtained, and then the average of T1 and T2 is calculated as the actual temperature.

[0088] Since the thermal management system can operate in a cooling mode or a heating mode, the temperature difference may be the absolute value of the difference between the target temperature and the actual temperature.

[0089] Step 10323, determining a first parameter corresponding to the remaining power from a preset first parameter corresponding table, and determining a second parameter corresponding to the temperature difference from a preset second parameter corresponding table.

[0090] The first parameter correspondence table is a pre-calibrated table representing the correspondence between the remaining power and the first parameter, and the second parameter correspondence table is a pre-calibrated table representing the correspondence between the temperature difference and the second parameter.

[0091] When calibrating the first parameter correspondence table, calibration can be performed on an actual vehicle. Under the premise of ensuring the normal operation of the thermal management system, the first parameter can be adjusted so that the power provided by the battery can meet the operation of the thermal management system and maintain a certain remaining power as much as possible, thereby obtaining the first parameter corresponding to different remaining powers.

[0092] When calibrating the second parameter correspondence table, calibration can be performed on an actual vehicle. Under conditions of different temperature differences between the actual temperature and the target temperature, the second parameter is adjusted to reduce the temperature difference to less than a certain temperature as quickly as possible, thereby obtaining the second parameter under different temperature difference conditions.

[0093] Step 10324: Based on the first parameter and the second parameter, the available base power and the generated power are calculated to obtain a thermal management power limit.

[0094] The above-mentioned first parameter corresponds to the remaining power, therefore, the first parameter can be used to limit the output power of the battery to ensure the basic performance of the vehicle. For example, as shown in the above formula (1), a is the first parameter. The second parameter corresponds to the temperature difference, therefore, the second parameter can be used to meet the power requirements of the thermal management system. For example, as shown in the above formula (1), b is the second parameter, which, when multiplied by the power generation, can reflect the degree of influence of the power generation on the temperature difference. According to the first parameter and the second parameter, the formula shown in formula (1) can be used to calculate the thermal management power limit. It should be noted that the formula shown in formula (1) is only one implementation method of the thermal management power control strategy. Any method that uses the first parameter to limit the output power of the battery and uses the second parameter to reflect the degree of influence of the power generation on the temperature difference to calculate the thermal management power is within the scope of this implementation.

[0095] This embodiment sets a first parameter correspondence table and a second parameter correspondence table to determine the first parameter and second parameter of the thermal management power control strategy. According to the actual remaining power and temperature difference of the target vehicle, the corresponding thermal management power limit can be calculated in a targeted manner. The calculated thermal management power limit has higher accuracy and compatibility with the actual scenario.

[0096] In some optional implementations, the first parameter correspondence table includes a first power correspondence table and a first temperature correspondence table, and the second parameter correspondence table includes a second power correspondence table and a second temperature correspondence table.

[0097] Step 10323 can be performed according to the following two situations:

[0098] Case 1: If the target working mode is a mode indicating that the target vehicle is parked outdoors, the parameter corresponding to the remaining power is determined as the first parameter from the preset first power correspondence table, and the parameter corresponding to the temperature difference is determined as the second parameter from the first temperature correspondence table.

[0099] The outdoor parking mode refers to various modes when the vehicle is parked outdoors for a long time. For example, the outdoor parking mode may include a camping mode, an outdoor vehicle mode, etc. The first power correspondence table and the first temperature correspondence table may be pre-calibrated in the outdoor parking mode.

[0100] As an example, a in the above formula (1) is the first parameter, and the first power correspondence table is shown in Table 1 below:

[0101] Table 1

[0102] SOC a 10％ 0 20％ 0.8 30％ 0.9 40％ 1

[0103] In Table 1, as the remaining power increases, the value of a gradually increases, that is, the more remaining power the battery has, the higher the power that the thermal management system can provide, so that the thermal management system can adjust the temperature more efficiently; the less remaining power the battery has, the less power the battery can provide to the thermal management system, reducing the risk of battery power failure.

[0104] Optionally, in Table 1, when the SOC is greater than 40%, a is 1.

[0105] In the above formula (1), b is the second parameter. Let T be the actual temperature, T m is the target temperature, |TT m | is the temperature difference, and the first temperature corresponding relationship table is shown in Table 2 below:

[0106] Table 2

[0107] <![CDATA[|T-T m |]]> b <![CDATA[|T-T m |≤5℃]]> 0.7 <![CDATA[5℃<|T-T m |≤10℃]]> 0.8 <![CDATA[10℃<|T-T m |]]> 0.9

[0108] In Table 2, the greater the temperature difference, the greater the value of the second parameter, which means that higher power can be obtained from the power generation power of the range extender to provide to the thermal management system, thereby improving the temperature control efficiency of the thermal management system.

[0109] Case 2: If the target working mode is not a mode indicating that the target vehicle is parked outdoors, first, determine the first target field corresponding to the current driving mode of the target vehicle from at least two driving modes included in the preset second power correspondence table.

[0110] The working mode is not a mode indicating that the target vehicle is parked outdoors, that is, the target vehicle may be in a driving state, and the first parameter can be determined according to the driving mode. The second power correspondence table can be pre-calibrated in different driving modes. Different driving modes occupy different fields in the second power correspondence table.

[0111] As an example, a in the above formula (1) is the first parameter, and the second power correspondence table is shown in Table 3 below:

[0112] Table 3

[0113] SOC a(Economic Mode) a(Comfort mode) a(Sports Mode) 5％ 0 0 0 10％ 0.5 0.6 0.7 20％ 0.8 0.8 0.9 40％ 1 1 1

[0114] In Table 3, each column corresponds to a driving mode, that is, each column is a field. In the same driving mode, as the remaining power increases, the value of a gradually increases, that is, the more remaining power, the higher the power that the battery can provide to the thermal management system, so that the thermal management system can adjust the temperature more efficiently; the less remaining power, the less power the battery can provide to the thermal management system, reducing the risk of battery power failure. For the same remaining power, the more the driving mode is sporty, the higher the power required by the thermal management system, and the larger the corresponding first parameter value.

[0115] Then, a parameter corresponding to the remaining power is determined from the first target field as the first parameter.

[0116] For example, if the current driving mode is the economic mode, the column corresponding to the economic mode in the above Table 3 is the first target field, and if the current remaining power is 20%, the first parameter is 0.8.

[0117] Then, a second target field corresponding to the current energy mode of the target vehicle is determined from the at least two energy modes included in the second temperature correspondence table.

[0118] Among them, the working mode is not a mode indicating that the target vehicle is parked outdoors, that is, it indicates that the target vehicle may be in a driving state, and at this time, the second parameter can be determined according to the energy mode. The second temperature correspondence table can be calibrated in advance under different energy modes. Different energy modes occupy different fields in the second temperature correspondence table.

[0119] As an example, b in the above formula (1) is the second parameter, and the second temperature correspondence table is shown in Table 4 below:

[0120] Table 4

[0121] <![CDATA[|T-T m |]]> b(Pure electric priority) b(Automatic) b(Fuel advance) <![CDATA[|T-T m |≤5℃]]> 0.5 0.7 0.7 <![CDATA[5℃<|T-T m |≤10℃]]> 0.6 0.8 0.8 <![CDATA[10℃<|T-T m |]]> 0.7 0.8 0.9

[0122] In Table 4, each column corresponds to an energy mode. The pure electric priority mode means that the vehicle will give priority to using battery power to meet driving needs and minimize the use of fuel. When the battery power drops to a certain level (for example, 15%), the range extender will start to supply power. The fuel priority mode means that in order to maintain driving performance, when the battery power is lower than a certain level (for example, 70%), the range extender will start to supply power. The automatic mode means that the vehicle will automatically switch to pure electric or fuel drive according to the current driving conditions, battery power and other factors. Each column in Table 4 is a field. In the same energy mode, as the temperature difference increases, the value of the second parameter gradually increases, indicating that higher power can be obtained from the power generation power of the range extender to provide to the thermal management system, thereby improving the temperature control efficiency of the thermal management system. For the same temperature difference, the more the energy mode is biased towards fuel, the higher power can be obtained from the range extender, and the corresponding second parameter value is larger. For the same row in Table 4, in the pure electric priority mode, the start-up frequency of the range extender is low, so the parameter b value is small, and the thermal management system obtains lower power from the range extender; in the automatic mode and the fuel priority mode, the parameter b value is large, and the thermal management system obtains higher power from the range extender.

[0123] Finally, from the second target field, a parameter corresponding to the temperature difference is determined as the second parameter.

[0124] For example, if the current energy mode is pure electric priority, the column corresponding to pure electric priority in the above Table 4 is the second target field, and if the current temperature difference is 6° C., the first parameter is 0.6.

[0125] This embodiment determines whether the vehicle is in an outdoor parking scenario or a non-outdoor parking scenario, and obtains a corresponding power correspondence table and a temperature correspondence table, so that the obtained parameters can better match the actual scenario of the vehicle, and the calculated thermal management power limit has higher scenario adaptability.

[0126] In some optional implementations, step 1022 may be performed as follows:

[0127] If the working mode with the highest thermal management priority is a mode under the scenario mode category indicating that the target vehicle is parked outdoors, when the remaining fuel amount of the target vehicle is greater than the preset fuel amount, the mode of parking outdoors is determined as the target working mode.

[0128] As an example, the scenario mode may include an indoor exhibition vehicle mode, an outdoor exhibition vehicle mode, a camping mode, a sleeping mode, etc. The above-mentioned camping mode and outdoor exhibition vehicle mode belong to the outdoor parking mode. When the target vehicle is parked outdoors, since the range extender can be started to generate electricity, when it is determined that a certain amount of fuel is remaining, the thermal management system can be started, and the range extender can continue to charge the battery to avoid battery depletion.

[0129] If the operating mode with the highest thermal management priority is the sleep mode under the scenario mode category, when the remaining power of the battery of the target vehicle is greater than or equal to a first preset power (eg, 20%), the sleep mode is determined as the target operating mode.

[0130] Among them, the sleep mode is the working mode selected by the user in the sleeping scene in the car. In the sleep mode, each device on the target vehicle operates according to the preset state corresponding to the sleep mode. For example, in the sleep mode, the drive motor, range extender, etc. on the target vehicle are set to be prohibited from starting, and the external unlocking of the door is prohibited, and only the seats, lights, audio and video entertainment and other functions are retained. When the target vehicle is in sleep mode, the passengers in the car may sleep in the car. At this time, for the safety of the passengers in the car, it is usually prohibited to start the range extender. Therefore, it is necessary to determine that the remaining power is greater than or equal to the first preset power before the thermal management mode is allowed to start. The first preset power can be a preset fixed value or can be set by the user. Optionally, an adjustable range of the remaining power can be pre-set, and the user can adjust the first preset power within this range.

[0131] If the operating mode with the highest thermal management priority is the normal control mode under the vehicle mode category, when the range extender of the target vehicle is in a startable state, or the remaining power is greater than or equal to the second preset power, the normal control mode is determined as the target operating mode.

[0132] The vehicle mode categories may include conventional control mode, remote interaction mode, DC charging mode, AC charging mode, etc. Conventional control mode is the mode selected by the target vehicle in a normal driving scenario. For example, in a non-charging state, if it is detected that the user is sitting in the driver's seat and the vehicle is powered on, it can automatically switch to conventional control mode. In conventional control mode, the user needs to enter the car to turn on the range extender and other devices in the car. At this time, if the range extender is in a startable state (the user enters the car, powers on the vehicle, and sets the range extender to a startable state), the range extender can generate electricity to charge the battery to avoid battery depletion. Alternatively, if the remaining power is greater than or equal to the second preset power, it is determined that the battery power is sufficient to supply the thermal management system at this time.

[0133] The second preset power level may be the same as or different from the first preset power level. For example, the second preset power level is 20%. The second preset power level may be a preset fixed value or may be set by the user. Optionally, an adjustable range of remaining power may be preset, and the user may adjust the second preset power level within the range.

[0134] If the working mode with the highest priority of thermal management is the charging mode under the vehicle mode category, the charging mode is determined as the target working mode.

[0135] The charging mode is the mode automatically selected by the target vehicle when charging. The charging mode may include a DC charging mode and an AC charging mode. In any charging mode, the thermal management system will not consume all the battery power, and the thermal management system may be activated at this time.

[0136] If the operating mode with the highest thermal management priority is the remote interaction mode under the vehicle mode category, when the remaining power is greater than or equal to the third preset power, the conventional control mode is determined as the target operating mode.

[0137] The remote interaction mode is a mode in which the user interacts with the target vehicle through a mobile phone or other device. At this time, the range extender is usually not allowed to start. Therefore, it is necessary to determine when the remaining power reaches a certain value before the thermal management mode is allowed to start. The third preset power may be the same as the first preset power and the second preset power, or different. For example, the third preset power is 20%. The third preset power can be a preset fixed value or can be set by the user. Optionally, an adjustable range of the remaining power can be pre-set, and the user can adjust the third preset power within the range.

[0138] It should be understood that since the working modes under the general energy mode category and driving mode category need to be started under the normal control mode under the vehicle mode category, any working mode under the energy mode category and driving mode category has the same thermal management high-power working start-up conditions as the above-mentioned normal control mode.

[0139] This embodiment makes the applicable scenarios for starting the thermal management system more specific by judging whether the thermal management high-power working start conditions are met according to the vehicle status in various working modes, which helps to improve the scenario adaptability of the thermal management system control.
