Description
Technical Field
[0001] The present invention relates to the technical field of thermal management of vehicles, and in particular to a thermal-related control method, device, system and computer-readable storage medium for vehicles. Background Art
[0002] The thermal management system of new energy vehicles contains a variety of heat-related modules. For example, the battery pack, drive module, and smart cockpit all have their own corresponding heat-related modules to achieve heating or heat dissipation of the battery pack, drive module, and smart cockpit. The multiple heat-related modules in the existing thermal management system of new energy vehicles are usually heated / dissipated separately based on their respective heating / heat dissipation requirements, and the heat-related modules cannot accurately achieve comprehensive allocation and utilization of heat. For example, when the battery pack is charged at low temperature, the static heating efficiency is low; when the vehicle is driving at low temperature, the waste heat generated by the battery pack and the waste heat generated by the electric drive module are directly dispersed into the air and are not effectively utilized, which affects the energy efficiency ratio of the heat dissipation system and is not conducive to the insulation of the battery pack; in the main driving conditions of electric vehicles, the water temperature and the actual temperature of the motor are low, resulting in too low oil temperature, which in turn leads to low efficiency of the electric drive module; and each heat-related module corresponds to a different environment, which makes the difference between them large, making it difficult to optimize the energy consumption of the system.

[0040] In view of the vehicle energy consumption optimization scenario, in order to achieve scientific and reasonable allocation and utilization of heat between various heat-related modules of the vehicle, improve the control accuracy of the heat transfer process between multiple heat-related modules of the vehicle, achieve rational reuse of vehicle waste heat, and reduce energy consumption, the present application provides a vehicle heat-related control method, a vehicle heat-related control device and system corresponding to the method, and a computer-readable storage medium. The following provides embodiments to describe the above method, device, system, and computer-readable storage medium in detail.
[0041] An embodiment of the present application provides a thermal-related control method for a vehicle, and the method may be applied to a thermal-related control module for performing thermal management on thermal-related modules of the vehicle. Figure 1 This is a flow chart of the thermal control method for a vehicle provided in the first embodiment of the present application. Figure 1 The thermal control method for a vehicle provided by this embodiment is described in detail. The embodiments described below are used to explain the principle of the method and are not intended to be limiting in actual use.
[0042] like Figure 1 As shown, the thermal-related control method for a vehicle provided in this embodiment includes the following steps:
[0043] S101, obtaining thermal state information of a battery module corresponding to a current state of the vehicle, and obtaining thermal demand information corresponding to the current state of the vehicle.
[0044] This step is used to obtain the thermal status information of the battery module corresponding to the current state of the vehicle and the thermal demand information corresponding to the current state of the vehicle. The current state of the vehicle may be one of the vehicle startup state, charging state, static heating state, etc. The thermal status information of the battery module corresponding to the current state of the vehicle may be the temperature data of the battery module corresponding to the vehicle when the vehicle is in the startup state or charging state. The thermal demand information corresponding to the current state of the vehicle refers to the heating demand or heat dissipation demand that matches the temperature data of the battery module of the vehicle when the vehicle is in the startup state or charging state.
[0045] Due to the high sensitivity of the battery module to the heat dissipation demand or heating demand, for example, there is a great safety hazard when the battery overheats due to untimely heat dissipation of the battery module; when the temperature of the battery module is too low, it will affect the battery characteristics and cause rapid power loss. Therefore, in this embodiment, the battery module is used as the main heat-related module of the vehicle, and the thermal demand information corresponding to the current state of the vehicle is mainly determined based on the thermal status information of the battery module.
[0046] Specifically, when the vehicle is in the vehicle starting state and the temperature of the battery module is lower than the first temperature, for example, when the vehicle is initially started, the temperature of the heat transfer medium of the battery module detected can be used as the temperature of the battery module (after the vehicle is started for a period of time, the temperature of the heat transfer medium lags behind the temperature of the battery module, and at this time the temperature of the battery module is the temperature of the battery module itself). The first temperature is a temperature threshold for measuring whether the battery module is in an overcooled environment, for example, 25°C. When the battery module temperature is lower than the first temperature, it indicates that the priority of quickly heating the battery module is higher. The thermal demand information corresponding to the current state of the vehicle may refer to: using the excess heat of the vehicle's drive module and / or the heat generated by the drive module to quickly heat the battery module, so that the battery module reaches the first temperature within a predetermined time;
[0047] When the vehicle is in the vehicle startup state, the temperature of the battery module is higher than the first temperature and lower than the second temperature, the second temperature is a temperature threshold for measuring whether the battery module is in an overheated environment. For example, the first temperature is 25°C and the second temperature is 45°C. The temperature of the battery module is higher than the first temperature and lower than the second temperature, indicating that the current temperature of the battery module is within the normal temperature range, and the battery module only needs to be cooled at a low load to offset the heat generated during the battery operation process. Therefore, the heat demand information corresponding to the current state of the vehicle may refer to: using the coldness of the smart cockpit to slowly cool the battery module, and using the waste heat of the battery module to optimize the driving efficiency of the driving module;
[0048] When the vehicle is in the vehicle startup state and the temperature of the battery module is higher than the second temperature, it indicates that the battery is in an overheated environment. The thermal demand information corresponding to the current state of the vehicle may refer to: using a cooling module corresponding to the battery module to quickly dissipate heat from the battery module, for example, by starting a dedicated cooling device for the battery module to independently dissipate heat from the battery module, so that the temperature of the battery module is restored to a preset temperature range within a predetermined time, and at the same time, using the cooling capacity of the smart cockpit to dissipate heat from the electric drive module;
[0049] When the vehicle is currently in a charging state and the temperature of the battery module is lower than the third temperature, it indicates that the battery module currently has a heating demand. The thermal demand information corresponding to the current state of the vehicle may refer to: heating the battery module by using excess heat of the drive module and / or heat generated by heating the drive module, so that the battery module reaches a third temperature within a predetermined time, and the third temperature may be equal to the first temperature or higher than the first temperature, for example, 35°C;
[0050] When the vehicle is currently in a charging state, the temperature of the battery module is higher than the fourth temperature, and the thermal demand information corresponding to the vehicle's current state may refer to: using the coldness of the smart cockpit to slowly dissipate the heat from the battery module, and using the waste heat from the battery module to optimize the driving efficiency of the driving module.
[0051] S102 , determining a heat transfer path between a plurality of heat-related modules of the vehicle based on the thermal state information and the thermal demand information.
[0052] After obtaining the thermal state information of the battery module and the thermal demand information corresponding to the current state of the vehicle in the above step, this step is used to determine the heat transfer path between multiple thermally related modules of the vehicle according to the above thermal state information and thermal demand information. The multiple thermally related modules are the above battery module, smart cockpit and drive module. In this embodiment, heat is transferred or exchanged between multiple thermally related modules through a heat transfer medium. Each thermally related module is provided with a transmission pipeline of a heat transfer medium. By connecting the transmission management between different thermally related modules, heat exchange between different thermally related modules can be achieved. The heat transfer medium can be water or other heat-conductive gases or fluids.
[0053] Corresponding to the above step S101, in this step, based on the thermal state information and the thermal demand information, the heat transfer path between the multiple thermally related modules of the vehicle is determined, which may specifically refer to:
[0054] When the vehicle is in the vehicle startup state and the temperature of the battery module is lower than the first temperature, the thermal demand information corresponding to the current state of the vehicle is: the battery module is heated by utilizing the excess heat of the drive module and / or the heat generated by the drive module, so that the battery module reaches the first temperature within a predetermined time; correspondingly, the heat transfer path between the multiple heat-related modules determined based on the thermal state information and the thermal demand information may refer to: a heat transfer path formed by the heat transfer medium after the outlet end of the heat transfer medium of the electric drive module is connected to the inlet end of the heat transfer medium of the battery module, and the outlet end of the heat transfer medium of the battery module is connected to the inlet end of the heat transfer medium of the electric drive module;
[0055] When the vehicle is in the whole vehicle starting state and the temperature of the battery module is higher than the first temperature and lower than the second temperature, the thermal demand information corresponding to the current state of the vehicle is: use the coldness of the smart cockpit to slowly dissipate the heat of the battery module, and use the waste heat of the battery module to optimize the driving efficiency of the drive module; correspondingly, the heat transfer path between multiple heat-related modules determined based on the thermal state information and the thermal demand information may refer to: after connecting the outlet end of the heat conduction medium of the smart cockpit with the inlet end of the heat conduction medium of the battery module, connecting the outlet end of the heat conduction medium of the battery module with the inlet end of the heat conduction medium of the electric drive system, and connecting the outlet end of the heat conduction medium of the electric drive system with the inlet end of the heat conduction medium of the smart cockpit, a heat transfer path formed by the heat conduction medium.
[0056] When the vehicle is in the vehicle startup state and the temperature of the battery module is higher than the second temperature, the thermal demand information corresponding to the current state of the vehicle is: using the cooling module corresponding to the battery module to quickly dissipate the heat of the battery module, so that the temperature of the battery module is restored to a preset temperature range within a predetermined time, and using the coldness of the smart cockpit to dissipate the heat of the electric drive module; correspondingly, the heat transfer path between multiple heat-related modules determined based on the thermal state information and the thermal demand information includes: turning on the cooling module corresponding to the battery module, connecting the outlet end of the heat conduction medium of the battery module to the inlet end of the heat conduction medium of the battery module, connecting the outlet end of the heat conduction medium of the smart cockpit to the inlet end of the heat conduction medium of the electric drive module, and connecting the outlet end of the heat conduction medium of the electric drive module to the inlet end of the heat conduction medium of the smart cockpit, and then forming a heat transfer path formed by the heat conduction medium.
[0057] The vehicle is currently in a charging state and the temperature of the battery module is lower than the third temperature. The thermal demand information corresponding to the current state of the vehicle is: the battery module is heated by utilizing excess heat of the drive module and / or heat generated by heating the drive module, so that the battery module reaches the third temperature within a predetermined time; correspondingly, the heat transfer path between multiple heat-related modules determined based on the thermal state information and the thermal demand information may refer to: after connecting the outlet end of the heat conduction medium of the electric drive module to the inlet end of the heat conduction medium of the battery module, and connecting the outlet end of the heat conduction medium of the battery module to the inlet end of the heat conduction medium of the electric drive module, a heat transfer path formed by the heat conduction medium.
[0058] The current state of the vehicle is a charging state, and the temperature of the battery module is higher than the fourth temperature. The thermal demand information corresponding to the current state of the vehicle is: use the coldness of the smart cockpit to slowly dissipate the heat of the battery module, and use the waste heat of the battery module to optimize the driving efficiency of the driving module. Correspondingly, the heat transfer path between multiple heat-related modules determined based on the thermal state information and the thermal demand information may refer to: after connecting the outlet end of the heat conduction medium of the smart cockpit to the inlet end of the heat conduction medium of the battery module, connecting the outlet end of the heat conduction medium of the battery module to the inlet end of the heat conduction medium of the electric drive system, and connecting the outlet end of the heat conduction medium of the electric drive system to the inlet end of the heat conduction medium of the smart cockpit, a heat transfer path formed by the heat conduction medium.
[0059] It should be noted that the various battery module temperatures corresponding to the vehicle when the vehicle is in the startup state or charging state, the thermal demand information set accordingly, and the heat transfer path determined based on the thermal state information and the thermal demand information are only exemplary illustrations and are not limitations for actual use. For example, the thermal demand information and the heat transfer path can be set corresponding to the different battery module temperatures corresponding to the vehicle in other states (for example, static heating or static cooling mode of the vehicle when it is stationary), which will not be repeated here.
[0060] S103, based on the heat transfer path, controlling the heat transfer status between the plurality of heat-related modules, so that the heat of the plurality of heat-related modules is transferred according to the heat transfer path.
[0061] After the above step determines the heat transfer path between the multiple heat-related modules of the vehicle, this step is used to control the heat transfer status between the multiple heat-related modules according to the above heat transfer path, so that the heat of the multiple heat-related modules is transferred according to the above determined heat transfer path.
[0062] In this embodiment, the control of the heat transfer status between the plurality of heat-related modules may specifically refer to: controlling the conduction or closing of the heat transfer medium corresponding to each heat-related module by a heat flow valve disposed between the plurality of heat-related modules, that is, the heat transfer medium corresponding to each heat-related module may converge at the heat flow valve, and the heat transfer path may be formed by controlling the opening and closing of the heat flow valve, thereby realizing heat exchange between the heat-related modules. In this embodiment, the heat flow valve may be a six-way valve.
[0063] In this embodiment, after controlling the conduction or shutdown between the heat transfer media corresponding to each heat-related module, it is also necessary to adjust the operating parameters of the heat-related equipment in the heat transfer path based on the temperature data of the above-mentioned heat transfer medium, so that the above-mentioned thermal demand information is met when the heat transfer between the multiple heat-related modules is performed according to the above-mentioned heat transfer path. The heat-related equipment can be a first electronic water pump provided on the circulation pipeline of the heat transfer medium of the drive module, a second electronic water pump provided on the circulation pipeline of the heat transfer medium of the battery module, a compressor provided for the smart cockpit, an electronic oil pump of the drive module, a heat exchanger provided for the battery module (the heat exchanger can share the above-mentioned compressor with the smart cockpit), etc. The operating parameters of the heat-related equipment can be the flow rate of the first electronic water pump, the flow rate of the second electronic water pump, the flow rate of the electronic oil pump, whether the heat exchanger is activated, whether the compressor is turned on, the compressor operation mode, the compressor speed, etc.
[0064] For example, in the above step S102, when the vehicle is in the whole vehicle starting state, the temperature of the battery module is lower than the first temperature, and the heat transfer path is to connect the outlet end of the heat transfer medium of the electric drive module with the inlet end of the heat transfer medium of the battery module, and connect the outlet end of the heat transfer medium of the battery module with the inlet end of the heat transfer medium of the electric drive module, since there may be a difference between the temperature of the battery module and the temperature of its heat transfer medium (for example, the temperature of the heat transfer medium lags behind the temperature of the battery module), therefore, when the above conduction or closing is achieved by the six-way valve, the temperature of the heat transfer medium (for example, water coolant) of the battery module can be further detected, and the flow rate of the first electronic water pump, the flow rate of the second electronic water pump, the flow rate of the electronic oil pump, whether the heat exchanger is activated, whether the compressor is turned on, the compressor operation mode, the compressor speed and other operating parameters of heat-related equipment can be specifically set according to the temperature of the heat transfer medium, so as to perform segmented control on the heating or cooling efficiency according to different heat transfer medium temperatures under the same heat transfer path, and then perform fine control on the heat transfer effect of the heat transfer path of the above vehicle, and optimize the overall energy consumption management of the vehicle.
[0065] The thermal-related control method of the vehicle provided in this embodiment obtains the thermal state information of the battery module corresponding to the current state of the vehicle, and obtains the thermal demand information corresponding to the current state of the vehicle; based on the thermal state information and the thermal demand information, determines the heat transfer path between multiple thermal-related modules of the vehicle, and the multiple thermal-related modules include a battery module, an intelligent cockpit, and a drive module; based on the thermal transfer path, controls the heat transfer status between the multiple thermal-related modules so that the heat of the multiple thermal-related modules is transferred according to the thermal transfer path. After obtaining the thermal state information and the thermal demand information of the battery module corresponding to the current state of the vehicle, the present invention determines the heat transfer path between the multiple thermal-related modules of the vehicle according to the thermal state information and the thermal demand information, and controls the heat transfer status between the multiple thermal-related modules based on the thermal transfer path, can respond to different thermal-related control strategies under different thermal state information and thermal demand information, can realize the reasonable allocation and utilization of heat between the thermal-related modules based on the thermal demand information of the current state of the vehicle in real time, improve the control accuracy of the heat transfer process between the thermal-related modules, realize the rational reuse of vehicle waste heat, and optimize the energy consumption of the whole vehicle.
