This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Example 1
The intelligent thermal management architecture in the first embodiment of the present application includes a heat collecting module, a thermal management executing module, and a control module connecting the heat collecting module and the thermal management executing module, wherein:
and the heat collection module is used for connecting the control module with each component and collecting the working information of each component so as to upload the collected working information to the control module. As one specific example, the operational information includes temperature, power, and status, further including on, off, standby, and malfunction.
As a specific example, a state refers to an operation mode or an operation condition of each component, such as on, off, standby, malfunction, or the like. These conditions can affect the heat generation and consumption of the components and therefore need to be collected and uploaded to the control module for thermal management. For example, the battery may be in a state of charge, discharge, overcharge, overdischarge, etc., which may cause the temperature and power of the battery to vary, thereby affecting the performance and life of the battery. Therefore, the heat collection module needs to monitor the state of the battery in real time and upload the state of the battery to the control module, so that the control module outputs a corresponding heat control signal according to the state of the battery to heat or cool the battery.
The control module comprises a VCU, and is connected with the heat collection module and the thermal management execution module and is used for calculating the heat demand and the distribution demand of each component according to the working information of each component received by the heat collection module and combining with a preset thermal management strategy and a target so as to output corresponding heat control signals to the thermal management execution module according to the heat demand and the distribution demand of each component.
As a specific example, a "preset thermal management strategy and objective" refers to a set series of thermal management rules and metrics, such as maximizing energy utilization efficiency, ensuring component temperatures within safe ranges, improving occupant comfort, etc., according to different operating conditions and requirements of a new energy vehicle. These strategies and targets are formulated according to analysis and research of the new energy automobile thermal management system, and aim to realize intelligent thermal management of the new energy automobile. For example, in low temperature environments, preset thermal management strategies and targets are to preferentially heat the battery to improve its performance and life; in a high temperature environment, a preset thermal management strategy and a target are to cool the electric control preferentially so as to prevent overheat damage and the like.
According to parameters such as temperature, power and state of each component, and preset thermal management strategies and targets, the control module adopts a mathematical model or algorithm to calculate heat input or output required by each component, priority and mode of heat exchange and the like. Specifically, the control module firstly judges whether each component needs to be heated or cooled according to the temperature parameters of each component and a preset temperature range; then judging whether each component needs to increase or decrease power according to the power parameters of each component and a preset power range; then judging whether each component needs to adjust a working mode or working conditions according to the state parameters of each component and a preset state range; and finally, calculating the optimal heat demand and distribution demand among all the components according to the judging result and a preset optimization target (such as energy utilization efficiency, safety, comfort and the like), and outputting corresponding heat control signals to the thermal management execution module according to the demands. See in particular fig. 1.
And the thermal management execution module is connected with each component and is used for receiving the heat control signal output by the control module so as to carry out intelligent thermal management on the components.
As a specific example, a "thermal management execution module" refers to a series of devices or units for effecting heat exchange, such as heat exchangers, fans, water pumps, compressors, expansion valves, heating units, microwave generators, and the like. The devices or units adjust the heat exchange mode and intensity among the components according to the heat control signals output by the control module, so as to realize heating or cooling of the components such as the motor, the electric control, the battery, the passenger cabin and the like. Specifically, the thermal management execution module activates or deactivates the corresponding device or unit or adjusts its operating parameters based on the content and instructions of the control signal to achieve the desired thermal management effect. For example, according to the content and instructions of the control signal, the rotating speed of the fan or the water pump is adjusted to change the flow rate and speed of the air or the water flowing through the heat exchanger; adjusting a compressor or an expansion valve to change the temperature and pressure of a working medium (e.g., refrigerant) according to the content and instructions of the control signal; the heating unit or the microwave generator is started or shut down to heat the battery and the like according to the content and the instruction of the control signal. See in particular fig. 2.
In the embodiment, the cloud computing platform is used for carrying out real-time monitoring and intelligent optimization on the working information of each component of the new energy automobile by utilizing methods such as big data analysis, deep learning and the like, so that the intelligent level and adaptability of the new energy automobile thermal management system are improved, and different working conditions and demands are met. Specifically, the following functions may be implemented by the cloud computing platform:
according to the actual running condition of the new energy automobile and external environment factors, a preset thermal management strategy and a target are dynamically adjusted to adapt to the changes of different temperatures, humidity, road conditions, driving habits and the like. For example, in a high altitude area, because air is thin, the power output of the new energy automobile is reduced, so that the cloud machine learning and artificial intelligence technology can automatically adjust a preset power range according to parameters such as altitude and the like, and send corresponding instructions to the control module so as to improve the power performance of the new energy automobile.
According to historical data and forecast data of each component of the new energy automobile, possible faults or anomalies are found and prevented in advance, so that the safety and reliability of the new energy automobile are improved. For example, through cloud machine learning and artificial intelligence technology, the remaining service life and performance decay of the battery can be predicted according to parameters such as charge and discharge times, temperature change and internal resistance change of the battery, and corresponding warnings or suggestions can be sent to the control module so as to replace or maintain the battery in time.
And providing customized thermal management service according to the personalized requirements and preferences of the users of the new energy automobile so as to improve the comfort level and user satisfaction of the new energy automobile. For example, through cloud machine learning and artificial intelligence technology, the temperature, humidity, air quality and the like of the passenger cabin can be automatically adjusted according to the driving habit, travel time, destination and other parameters of the user, and corresponding instructions are sent to the control module so as to meet the personalized requirements of the user.
