[0031] In order to make the above and other features and advantages of the present application more clear, the present application is further described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explaining to those skilled in the art and are only exemplary and not restrictive.

[0032] In the following description, many specific details are set forth to provide a thorough understanding of the present application. However, it is apparent to those skilled in the art that specific details need not be adopted to practice the present application. In other cases, well-known steps or operations are not described in detail to avoid blurring the present application.

[0033] The method for determining the available power for thermal management of a vehicle provided in an embodiment of the present application may be executed by the device for determining the available power for thermal management of a vehicle provided in an embodiment of the present application, and the device may be configured in an electronic device.

[0034] refer to Figure 1 The present application provides a method for determining available power for thermal management of a vehicle, the method comprising step S11, step S13 and step S15.

[0035] Step S11, obtaining the current parameters of the vehicle.

[0036] Step S13, determining the current operating condition of the vehicle according to the current parameters of the vehicle, the current operating condition of the vehicle being a driving condition or a charging condition.

[0037] Specifically, in the present application, the vehicle control unit (VCU) can be used as the execution subject of the present application, wherein the vehicle control unit can obtain the current parameters of the vehicle. It should be noted that the current parameters can be used to determine the current working condition of the vehicle. It should be noted that the current working condition of the vehicle may include a driving condition or a charging condition. The current parameters can be obtained by other controllers of the vehicle and sent to the vehicle control unit. For example: the accelerator pedal controller of the vehicle obtains the accelerator pedal parameters of the vehicle, the brake pedal controller of the vehicle obtains the brake pedal parameters of the vehicle, or the battery management system (BATTERY MANAGEMENT SYSTEM, BMS) of the vehicle obtains the parameters of the vehicle battery pack. Among them, if the current parameters of the vehicle are the pedal parameters of the vehicle, the vehicle control unit can establish a communication relationship with the pedal controller of the vehicle, wherein the pedal controller of the vehicle can obtain the current pedal parameters of the vehicle and send the pedal parameters to the vehicle control unit. After the vehicle control unit obtains the pedal parameters, it determines whether the pedal parameters meet the preset parameters. When the pedal parameters meet the preset parameters, the working condition of the vehicle is characterized as a driving condition. This embodiment can accurately determine the current operating condition of the vehicle by determining the current parameters of the vehicle, thereby accurately determining the available power for thermal management of the vehicle.

[0038] In an optional embodiment, the driving condition may include: any one of a creeping condition, an acceleration condition, a gliding condition and a braking condition; the charging condition may include: any one of a DC charging condition, an AC charging condition, a DC charging preheating condition and an AC charging preheating condition.

[0039] Step S15, determining the available power for vehicle thermal management based on the current operating condition of the vehicle.

[0040] In this embodiment, after the vehicle controller determines the current working condition of the vehicle, the available power for vehicle thermal management can be determined according to the current working condition of the vehicle. The method for determining the available power for vehicle thermal management under different working conditions is described in detail below.

[0041] This application can make the thermal management system of the vehicle work normally when the vehicle is in the charging and driving state, thereby improving the safety of the vehicle. It solves the technical problem in the prior art that the vehicle thermal management method is only calculated under the driving condition, and the safety of the vehicle in other working conditions cannot be guaranteed.

[0042] like Figure 2 As shown, in an optional embodiment, the current operating condition of the vehicle is a driving condition, wherein in step S15, based on the current operating condition of the vehicle, the available power for vehicle thermal management is determined, which may include step S151 and step S152.

[0043] Step S151, obtaining the available discharge power of the battery pack and the actual power of the DC converter.

[0044] Step S152: Determine the available power for vehicle thermal management based on the available discharge power of the battery pack and the actual power of the DC converter.

[0045] In this embodiment, the vehicle controller can establish a communication relationship with the battery management system and the DC converter, wherein the battery management system can obtain the available discharge power of the battery pack and send the available discharge power of the battery pack to the vehicle controller, and the DC converter can send its actual power to the vehicle controller. The vehicle controller can determine the available power for vehicle thermal management based on the obtained available discharge power of the battery pack and the actual power of the DC converter.

[0046] It should be noted that the available power of the battery pack is used to represent the maximum current that the battery pack can output multiplied by the battery output voltage at that time, and the actual power of the DC converter is used to represent the energy consumed by the DC converter per unit time during actual power consumption.

[0047] In an optional embodiment, after determining the vehicle thermal management available power based on the available discharge power of the battery pack and the actual power of the DC converter in step S152, the method further includes: determining the vehicle driving available power based on the vehicle thermal management available power, the available power of the battery pack and the actual power of the DC converter.

[0048] In this embodiment, when the vehicle is in a driving condition and the vehicle thermal management available power is determined, the vehicle controller can determine the vehicle driving available power through the vehicle thermal management available power, the available power of the battery pack, and the actual power of the DC converter. This embodiment preferentially calculates the vehicle thermal management available power to ensure that when the vehicle is in a driving condition, the vehicle can be fully cooled through the preferentially calculated vehicle thermal management available power, thereby avoiding the situation where the vehicle parts are overheated under high pressure.

[0049] It should be noted that the vehicle driving available power is used to represent the maximum driving power that the vehicle can output.

[0050] In an optional embodiment, when the vehicle is in a charging state, it is also necessary to prioritize the calculation of the available power for vehicle thermal management.

[0051] In an optional embodiment, the vehicle is currently in a charging condition, and the charging condition is a DC charging preheating state or an AC charging preheating state. In step S15, based on the vehicle's current operating condition, the available power of the vehicle thermal management is determined, which may include: step S153 and step S154.

[0052] Step S153, obtaining the actual charging power of the battery pack and the actual power of the DC converter.

[0053] Step S154, determining the available power for vehicle thermal management based on the actual charging power of the battery pack and the actual power of the DC converter.

[0054] In this embodiment, the vehicle controller can establish a communication relationship with the vehicle's preheating controller, and the vehicle controller can determine which preheating state the vehicle is in through the vehicle's preheating controller, such as a DC charging preheating state or an AC charging preheating state. When the vehicle is in a DC charging preheating state or an AC charging preheating state, the vehicle controller can obtain the actual charging power of the battery pack and the actual power of the DC converter, and determine the vehicle's thermal management available power through the actual charging power of the battery pack and the actual power of the DC converter. In this embodiment, when the battery pack temperature is too low to discharge, the actual charging power is used as the available power limit of the thermal management system during the vehicle's charging preheating process to avoid the situation where the battery available power is 0 and cannot be preheated.

[0055] It should be noted that the actual charging power of the battery pack is used to characterize the power of the battery pack during the actual charging process.

[0056] In an optional embodiment, the current operating condition of the vehicle is a charging condition, and the charging condition is an AC charging state. In step S15, based on the current operating condition of the vehicle, determining the available power for vehicle thermal management may include: step S155 and step S156.

[0057] Step S155, obtaining the actual charging power fed back by the charging device.

[0058] Step S156: Determine the available power for vehicle thermal management based on the actual charging power fed back by the charging device.

[0059] In this embodiment, the vehicle controller can establish a communication relationship with the charging device, wherein the charging device can obtain the actual charging power when charging the battery pack and send the actual charging power to the vehicle controller. The vehicle controller determines the available power for vehicle thermal management according to the actual charging power.

[0060] In an optional embodiment, when the vehicle is in an AC charging state, the actual charging power of the charging device is the available power for vehicle thermal management.

[0061] Optionally, the charging device may be a charger.

[0062] In an optional embodiment, the current operating condition of the vehicle is a charging condition, and the charging condition is a DC charging state. In step S15, based on the current state of the vehicle, determining the available power for vehicle thermal management may include the following steps.

[0063] Get the available discharge power of the battery pack and the actual power of the DC converter.

[0064] Determine whether the available discharge power of the battery pack is higher than the preset available power.

[0065] Determine whether the actual charging power of the DC converter is higher than the rated power of the thermal management system.

[0066] When the available power of the battery pack is higher than the preset available power and the actual charging power of the DC converter is higher than the rated power of the thermal management system, the vehicle thermal management available power is determined based on the available discharge power of the battery pack and the actual charging power of the DC converter.

[0067] In this embodiment, when the vehicle is in a DC charging state, the vehicle controller obtains the available discharge power of the battery pack and the actual power of the DC converter. The vehicle controller needs to determine whether the available discharge power of the battery pack is higher than the preset available power and whether the actual charging power of the DC converter is higher than the rated power of the thermal management system. If both are higher, the vehicle thermal management available power is determined based on the available discharge power of the battery pack and the actual charging power of the DC converter.

[0068] In an optional embodiment, the difference between the available discharge power of the battery pack and the actual power of the DC converter is determined as the available power for vehicle thermal management.

[0069] In an optional embodiment, judging whether the available discharge power of the battery pack is higher than the preset available power can be used as the first condition, and judging whether the actual power of the DC converter is higher than the rated power of the thermal management system can be used as the second condition. When the first condition is met, that is, the available discharge power of the battery pack is higher than the preset available power, it is judged whether the second condition is met. When both conditions are met, the available power for thermal management of the vehicle is determined based on the available discharge power of the battery pack and the actual power of the DC converter. On the contrary, when the first condition is not met, there is no need to judge the second condition. This embodiment can determine the available power for thermal management of the vehicle more quickly.

[0070] In an optional embodiment, in step S15 , based on the current state of the vehicle, the available power for vehicle thermal management is determined, and the following steps may also be included.

[0071] When the available power of the battery pack is less than or equal to the preset available power or the actual charging power of the DC converter is less than or equal to the rated power of the thermal management system, the vehicle thermal management available power is determined based on the actual charging power of the DC converter.

[0072] In this embodiment, when the first condition is not met, or the first condition is met and the second condition is not met, the available power for vehicle thermal management is determined based on the actual power of the DC converter.

[0073] In an optional embodiment, when the communication between the vehicle controller and the battery management system is lost, or when the communication between the vehicle controller and the charger is lost during AC charging, the available power of the thermal management system is 0 kW.
