Key components of new energy vehicles, such as batteries, motors, and electronic control systems, generate a significant amount of heat during vehicle operation. The performance and lifespan of these components are closely related to temperature; excessively high or low temperatures can have adverse effects. For example, batteries age more rapidly at high temperatures, reducing driving range and lifespan; at low temperatures, the battery's internal resistance increases, reducing charging and discharging efficiency. Overheating can also lead to performance degradation, malfunctions, or even damage to the motor and electronic control system.

Attached Figure Description

[0019] The invention will now be further described with reference to the accompanying drawings.

[0020] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 , This embodiment provides: a thermal management system for new energy vehicles, including: The multi-state data acquisition module is used to capture in real time the specific temperature and thermal energy data generated by the battery, motor and key electronic control components when the vehicle is in various driving states such as starting, acceleration, high speed and climbing. The multi-state data acquisition module includes: A battery temperature sensor array is placed at different key locations on the battery to accurately collect battery temperature data under various driving conditions. The battery temperature sensor group adopts a distributed arrangement, with temperature sensors installed on the surface of each individual cell in the battery pack and at key connection points inside the battery pack. For example, sensors are installed on the four sides of the square battery and at the positive and negative terminals of the battery pack, which can comprehensively monitor the temperature distribution of the battery. When the vehicle is climbing a hill, the battery outputs high power, and these sensors can obtain the temperature changes at different locations of the battery in real time, accurately collect the temperature data of the battery under various driving conditions, and comprehensively monitor the temperature distribution of the battery. The motor temperature sensor group is set in the key heat-generating parts of the motor, including at least three sensors in different locations, respectively located in the stator, rotor and key heat dissipation areas of the motor housing. For example, sensors are set near the windings of the stator, on the surface of the iron core of the rotor and at the root of the heat dissipation fins of the motor housing. When the vehicle is traveling at high speed, the motor generates a lot of heat. These sensors can obtain the temperature information of the motor under different driving conditions and accurately reflect the heating status of the motor. The motor temperature sensor group includes at least three sensors located at different locations, namely the stator, rotor, and key heat dissipation areas of the motor housing. The electronic control temperature sensor group is installed on the core components of the electronic control system. Independent temperature sensors are set for the power module and the core components of the control chip in the electronic control system. For example, sensors are installed on the heat sink of the power module and the surface of the control chip to collect temperature data of the electronic control components in real time so as to detect potential overheating problems in the electronic control system in a timely manner. The electronically controlled temperature sensor group sets up independent temperature sensors for the power module and the core components of the control chip in the electronic control system.

[0023] The thermal energy acquisition unit works in conjunction with the aforementioned sensor groups to convert the acquired temperature data into corresponding thermal energy data. For example, based on the battery surface temperature acquired by the sensors, combined with parameters such as the battery's specific heat capacity and mass, the temperature data is converted into thermal energy data generated by the battery through a specific calculation formula, providing more comprehensive information for subsequent data analysis. The data analysis and anomaly identification module communicates with the multi-state data acquisition module to analyze and calculate the acquired temperature and thermal energy data, identify whether the thermal energy is within the normal operating range, and detect overheating and overcooling anomalies. The data analysis and anomaly detection module includes: The data preprocessing unit performs filtering and noise reduction preprocessing operations on the collected raw temperature and thermal energy data; The normal operating range storage unit stores data on the normal temperature and thermal energy operating ranges of the battery, motor, and electronic control components under different driving conditions. This data is acquired through the following methods: During the vehicle development phase, extensive laboratory testing and simulated driving trials are conducted to collect temperature and thermal energy data for the battery, motor, and electronic control components under different driving conditions, and statistical analysis is performed to determine the normal operating range; During actual vehicle use, operational data from each component is continuously collected, and machine learning algorithms are used to dynamically update and optimize the data in the normal operating range storage unit; for example, as the vehicle's mileage increases, battery performance gradually degrades, and its normal operating temperature range may change. Machine learning algorithms can adjust the stored normal operating range data in real time to better reflect actual conditions. The comparison and analysis unit compares and analyzes the preprocessed data with the data in the normal range storage unit to determine whether the current thermal energy is within the normal operating range. For example, after the collected motor temperature data is preprocessed, it is compared with the normal temperature range of the motor under the same driving conditions in the normal range storage unit. If it exceeds the range, the motor temperature is judged to be abnormal.

[0024] The abnormal alarm unit issues corresponding overheat or overcooling alarm signals when the comparison and analysis unit determines that an abnormal situation has occurred. For example, when the battery temperature is too high, the alarm information is displayed on the vehicle's instrument panel, and an audible alarm is triggered to remind the driver to take timely measures.

[0025] The road condition perception and parameter adjustment module is used to perceive different road conditions when the vehicle is driving on urban roads, highways, and mountain roads. Based on the temperature differences generated under different road conditions, it dynamically adjusts the heat exchange power and heat recovery intensity parameters to achieve precise matching between thermal management and driving scenarios.

[0026] The road condition perception and parameter adjustment module includes: The road condition recognition unit acquires road condition information of the vehicle's current driving through the vehicle's navigation system, wheel speed sensors, and acceleration sensors, including road type, slope, and curve radius. For example, the navigation system can provide information such as whether the vehicle is currently driving on a city road, highway, or mountain road; the wheel speed sensors can measure the rotational speed of the wheels and, combined with information such as the vehicle's transmission ratio, calculate the vehicle's speed; the acceleration sensors can detect changes in the vehicle's acceleration to determine whether the vehicle is going uphill, downhill, or turning. The parameter adjustment strategy storage unit stores pre-set adjustment strategies for heat exchange power and heat recovery intensity parameters for different road conditions. These adjustment strategies are based on the following factors: the differences in the heating characteristics of the battery, motor, and electronic control components under different road conditions; for example, when driving on urban roads, the vehicle frequently starts and stops, and the heating of the battery and motor is different from that when driving at high speeds; the impact of the vehicle's driving speed and load on the thermal management system under different road conditions, such as when climbing a hill fully loaded, the vehicle's power demand is high, and the components heat up severely, requiring a greater heat exchange power; and the effect of external environmental meteorological conditions such as temperature and humidity on the thermal management effect, such as the thermal management system's heat dissipation efficiency decreasing in high-temperature and high-humidity environments, requiring parameter adjustments to improve heat dissipation. The parameter adjustment execution unit, based on the road condition information identified by the road condition recognition unit, calls the corresponding adjustment strategy from the parameter adjustment strategy storage unit and dynamically adjusts the relevant parameters of the thermal management system. For example, when a vehicle travels from an urban road to a highway, the road condition recognition unit detects a change in road type, and the parameter adjustment execution unit calls the parameter adjustment strategy for highway driving from the parameter adjustment strategy storage unit to increase heat exchange power to meet the higher heat demand of various components during high-speed driving.

[0027] Data in a normal interval storage unit is obtained in the following ways: During the vehicle development phase, extensive laboratory tests and simulated driving trials are conducted to collect temperature and thermal energy data of various components such as batteries, motors, and electronic controls under different driving conditions. Statistical analysis is then performed to determine the normal operating range. During actual vehicle use, operational data from various components are continuously collected, and machine learning algorithms are used to dynamically update and optimize the data in the normal range storage unit.

[0028] The thermal management execution module communicates with the road condition perception and parameter adjustment module, and performs corresponding thermal management operations based on dynamically adjusted parameters, including: The heat exchanger control unit, based on adjusted heat exchange power parameters, controls the heat exchanger's operating state and regulates the flow and temperature of coolant or air to effectively cool or heat the battery, motor, and electronic control components. Employing an intelligent control algorithm, it precisely controls the heat exchanger's valve opening and fan speed based on real-time temperature data and adjusted heat exchange power parameters. For example, when the battery temperature is too high, the heat exchanger control unit increases the coolant flow and fan speed to accelerate battery heat dissipation, based on real-time temperature data and adjusted high heat exchange power parameters. The heat exchanger control unit uses an intelligent control algorithm to precisely control the valve opening and fan speed of the heat exchanger based on real-time collected temperature data and adjusted heat exchange power parameters. The heat recovery unit, based on adjusted heat recovery intensity parameters, recovers waste heat generated during vehicle operation and converts it into usable thermal energy for use in other vehicle systems or to provide heating for the vehicle interior. The heat recovery unit includes a heat exchanger and a heat storage device. The heat exchanger recovers waste heat, for example, by exchanging heat with the high-temperature gas discharged from the motor. The heat storage device stores the recovered thermal energy and releases it as needed by the vehicle, such as using the stored thermal energy to preheat the battery when the vehicle starts, thereby improving battery performance.

[0029] The heat recovery unit includes a heat exchanger and a heat storage device. The heat exchanger is used to recover waste heat, and the heat storage device stores the recovered heat energy and releases it as needed by the vehicle.

[0030] The remote monitoring and diagnostic module connects to the vehicle's thermal management system via a wireless communication network and supports the following functions: Real-time remote monitoring of the vehicle's thermal management system's operating status, including temperature data of each component, thermal management parameters, and abnormal alarm information; for example, maintenance personnel can use the remote monitoring platform to view the temperature of the vehicle's battery, motor, and electronic control system in real time, as well as parameters such as the heat exchange power and heat recovery intensity of the thermal management system, and understand the vehicle's thermal management status in a timely manner. The system analyzes and diagnoses the collected remote data to identify potential thermal management issues in advance and provides corresponding maintenance recommendations. For example, by analyzing a large amount of remote data, it was found that the motors of a certain batch of vehicles are prone to overheating under specific road conditions. The system promptly notifies the vehicle owners to carry out maintenance and provides recommendations such as replacing the motor cooling fan.

[0031] Remote software upgrades of the thermal management system can be implemented to continuously optimize the system's performance and functionality. For example, as technology advances, more efficient thermal management algorithms can be developed, and these new algorithms can be updated into the vehicle's thermal management system via remote software upgrades to improve the system's thermal management efficiency.

[0032] It should be noted that the system's workflow is as follows: After the vehicle starts, the multi-state data acquisition module begins to collect the temperature and thermal energy data of the battery, motor, and electronic control in real time, and transmits them to the thermal energy acquisition unit for data conversion. The converted data enters the data analysis and anomaly identification module. After data preprocessing, comparison and analysis with normal range data, etc., it is determined whether there is an abnormality. If there is an abnormality, the anomaly alarm unit issues an alarm signal. Meanwhile, the road condition perception and parameter adjustment module obtains the current road condition information of the vehicle through the road condition recognition unit, calls the corresponding adjustment strategy from the parameter adjustment strategy storage unit, and the parameter adjustment execution unit dynamically adjusts the relevant parameters of the thermal management system. Based on the adjusted parameters, the thermal management execution module executes corresponding thermal management operations through the heat exchanger control unit and the heat recovery unit to achieve effective thermal management of the battery, motor, and electronic control system. In addition, the remote monitoring and diagnostic module monitors the vehicle's thermal management system in real time, analyzes and diagnoses the collected remote data, and provides functions such as remote software upgrades to ensure that the thermal management system is always in optimal working condition.
