[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0037] In a first aspect, an embodiment of the present application provides a method for controlling exhaust gas in a water channel of an electric vehicle battery.

[0038] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the method for controlling the exhaust of the water circuit of an electric vehicle battery in this application. Figure 1 As shown, the electric vehicle battery water channel exhaust control method includes:

[0039] S1: Determine the installation position of the exhaust valve body in the battery water path based on the vehicle operation history data to install the exhaust valve body and the sensor;

[0040] That is, after the installation position of the exhaust valve body is confirmed, the installation position of the sensor can be determined accordingly, so as to carry out the installation operation of the exhaust valve body and the sensor;

[0041] S2: The water channel information is acquired in real time through sensors, and combined with the battery working conditions, the exhaust control of the exhaust valve body is realized by using preset control logic.

[0042] Specifically, the water channel information is acquired through a sensor installed in the battery water channel, and then the exhaust valve body is controlled by a preset control logic in combination with the battery working condition, thereby achieving exhaust control of the battery water channel.

[0043] Further, in one embodiment, the installation position of the exhaust valve body in the battery water path is determined based on the vehicle operation history data, and the exhaust valve body and the sensor are installed, specifically including:

[0044] S101: Obtaining and analyzing historical operation data of each vehicle to obtain a location in the battery water channel where the probability of gas accumulation is greater than a preset value;

[0045] S102: Install the exhaust valve body at the determined position, and install a sensor between the battery and the exhaust valve body, and the sensor is close to the exhaust valve body; wherein the exhaust valve body and the sensor are both located on the water outlet pipe of the battery water circuit. The sensor includes a temperature sensor and an air pressure sensor, and the water circuit information includes the gas pressure and the temperature in the water circuit.

[0046] Specifically, the historical operation data of multiple vehicles can be obtained to determine the parts of the battery water circuit that are prone to gas accumulation, and the exhaust valve body can be installed. During the installation of the exhaust valve body, professional tools are used to ensure that the valve body and the water circuit are tightly connected and leak-free, and the sealing gasket at the connection is made of high-temperature resistant and corrosion-resistant materials. For the installation of the sensor, the sensor should be accurately installed close to the exhaust valve body and in a position where it can fully contact the water circuit to ensure the accuracy of the test data. At the same time, when installing the sensor, pay attention to the protection of the sensor to prevent it from external damage.

[0047] See also Figure 2 The figure shows the installation diagram of the exhaust-related device. The exhaust valve body specifically includes a control valve body and a vacuum pump. The exhaust valve body is located on the water outlet pipe of the battery water circuit. The temperature sensor and the air pressure sensor are installed close to the exhaust valve body and are located between the exhaust valve body and the battery. Furthermore, a control component is also provided at the temperature sensor and the air pressure sensor. The control component is used to realize the exhaust control of the exhaust valve body according to the water circuit information and the battery working condition using a preset control logic.

[0048] For the control component, during installation, the control component can be installed in the control unit of the electric vehicle, and a reliable connection with the exhaust valve body and the sensor can be achieved through a dedicated data line and control line, and the connection lines are reasonably laid out to avoid electromagnetic interference and mechanical damage.

[0049] The hardware involved in the electric vehicle battery water channel exhaust control method of the present application is specifically described as follows.

[0050] For the exhaust valve body, new materials and unique valve core design are used to ensure that the valve body can quickly and accurately control the gas discharge during long-term use, and has good sealing performance to prevent gas backflow.

[0051] For sensors, high-precision temperature sensors and air pressure sensors are used, which can monitor subtle changes in the battery water circuit in real time and accurately, with a detection frequency of up to times per second.

[0052] For the control components, microcontrollers with powerful computing capabilities can be used, which can quickly process massive data from sensors and make precise control decisions based on preset complex algorithms and models.

[0053] For the connecting pipes, corrosion-resistant and high-strength materials are used, and the inner wall is smooth to reduce the gas flow resistance. At the same time, the connection with the exhaust valve body and the battery water channel adopts a special sealing structure to ensure no leakage.

[0054] Furthermore, in one embodiment, the preset control logic includes normal exhaust control logic, emergency heat dissipation control logic, pre-control logic, and intelligent adjustment control logic.

[0055] The normal exhaust control logic is to monitor the gas pressure in the battery water circuit based on the sensor, and when the gas pressure exceeds the preset safety upper limit, open the exhaust valve body, and control the opening of the exhaust valve body based on a positive correlation method according to the extent to which the gas pressure exceeds the preset safety upper limit.

[0056] Specifically, when the sensor detects that the gas pressure in the battery water circuit exceeds the preset safety upper limit, the control component quickly opens (within milliseconds of reaction time) the exhaust valve body to discharge the gas. At the same time, it also dynamically adjusts the degree of opening of the exhaust valve body based on a positive correlation method according to the extent to which the gas pressure exceeds the preset safety upper limit, so as to achieve precise exhaust.

[0057] The emergency heat dissipation control logic is based on the sensor's monitoring of the gas temperature in the battery water path. When the gas temperature exceeds the set warning value, the emergency heat dissipation mode is entered and the exhaust valve body is controlled to be fully opened.

[0058] Specifically, when the sensor detects that the gas temperature in the battery water circuit exceeds the set warning value, the control component immediately activates the emergency heat dissipation mode and fully opens the exhaust valve body to enhance the heat dissipation effect.

[0059] The pre-control logic is that when the battery is in a charging condition, if the charging current rising rate is greater than the set rising rate or the charging time is greater than the set time, the switching frequency and opening time of the exhaust valve body are increased in advance.

[0060] Specifically, during the battery charging process, if it is detected that the charging current is rising too fast or the charging time is too long, the control component will predict that more gas may be generated in the battery water path and increase the switching frequency and opening time of the exhaust valve body in advance.

[0061] The intelligent adjustment control logic is that when the battery is in a discharge condition, if the battery discharge power exceeds a preset percentage of the rated power and lasts longer than a preset time, the exhaust rate of the exhaust valve body is increased.

[0062] Specifically, during the battery discharge process, the control component intelligently adjusts the working mode of the exhaust valve body according to the discharge power and duration. For example, when the discharge power exceeds a preset percentage of the rated power and the duration is greater than a preset time, the control component automatically increases the exhaust force.

[0063] For the electric vehicle battery water circuit exhaust control method of the present application, in the actual application process, when the electric vehicle is started, a comprehensive self-check is automatically performed, including the working status of the sensor, control component and exhaust valve body. After the self-check is correct, the sensor, control component and exhaust valve body automatically start working to monitor the gas situation in the water circuit in real time, so as to perform exhaust control. During the battery charging and discharging process, the control component will automatically and seamlessly control the opening and closing of the exhaust valve body according to the preset control logic and the real-time collected data. The whole process does not require driver intervention, but the relevant data will be displayed in real time on the vehicle's information display screen for the driver to understand.

[0064] Furthermore, if the driver needs to manually control the exhaust under special circumstances, the driver can operate it through a specially set button or touch screen on the control panel of the electric vehicle. In the manual control mode, the driver can select different exhaust intensities and working modes.

[0065] It should be noted that the working status of sensors, control components and exhaust valve bodies should be checked regularly, and a comprehensive inspection should be carried out on the sensors, control components and exhaust valve bodies at set intervals or mileage, including the sealing performance of the exhaust valve body, the accuracy of the sensors, the operating status of the control components, etc. The inspection should be carried out by professional technicians using special testing equipment. At the same time, impurities in the water channel should be avoided. In daily use, attention should be paid to keeping the battery water channel clean, regularly changing the coolant, and using a filter to prevent impurities from entering the water channel. For protection during maintenance and battery replacement, when performing battery maintenance or replacement operations, the operator needs to understand the location and structure of the sensors, control components, and exhaust valve bodies in advance, and take necessary protective measures to avoid accidental damage to the sensors, control components, and exhaust valve bodies.

[0066] This application adopts a special exhaust valve body structure. The valve core adopts a unique shape and material, and cooperates with a precision-machined valve seat to achieve rapid and leak-free discharge of gas. The flow channel design inside the valve body has been optimized to minimize the resistance to gas flow. Using intelligent control logic, based on advanced sensor data fusion technology and complex fuzzy logic algorithms, the control component can accurately judge the gas condition in the waterway in real time and quickly make the optimal exhaust decision. The control logic also has self-learning and adaptive capabilities, and can continuously optimize the exhaust strategy as the battery life increases and environmental conditions change. At the same time, the sensors, control components, and exhaust valve bodies are reasonably laid out, and the connections between the various components are tight and stable. The length, diameter, and bending angle of the connecting pipes are carefully designed to ensure smooth gas flow while reducing the space occupied by the vehicle.

[0067] The structural design of the exhaust device in this application includes the specific structure, size, and material of the exhaust valve body, the type, installation location, and accuracy of the sensor, the model and internal algorithm of the controller, and the material, shape, and connection method of the connecting pipe, etc. The specific algorithms and procedures of the control logic cover the processing method of sensor data, the threshold setting for judging gas pressure and temperature anomalies, the decision algorithm for exhaust valve body switch control, and the program code for adaptive learning and optimization, etc. The connection method between the exhaust device and the water circuit of the electric vehicle battery involves the structure of the connection part, the sealing method, the fixing method, and the integration and collaborative working mode with the battery water circuit system, etc.

[0068] The electric vehicle battery water channel exhaust control method of the embodiment of the present application has efficient exhaust and heat dissipation optimization, can quickly and thoroughly remove the gas in the water channel, and significantly improve the heat dissipation effect of the battery, thereby effectively maintaining the battery within the ideal operating temperature range, ensuring its stable performance, not only extending the cruising range after a single charge, but also reducing the battery performance degradation caused by high temperature; the structure is simple and maintenance is convenient, the exhaust-related device has a simple and compact structure, and the design of each component has fully considered the convenience of installation and maintenance, which can not only reduce the initial installation cost, but also greatly shorten the time and labor costs required for subsequent maintenance, and improve the vehicle's utilization efficiency; intelligent control and safety and reliability, with the corresponding control logic, can adapt to various working conditions of the battery and complex conditions in the water channel in real time, automatically adjust the exhaust strategy, effectively improve the reliability and safety of the exhaust-related devices, reduce the risk of failure due to poor exhaust, and provide strong guarantee for the stable operation of electric vehicles.
