Description

Technical Field

[0001] The present application relates to the technical field of light trucks, and in particular to a method, device and medium for automatically replenishing battery power. Background Art

[0002] In today's rapidly developing logistics and transportation industry, light commercial vehicles are becoming increasingly important and diversified as a key link connecting all links in the supply chain. With the rapid advancement of technology and the booming e-commerce, people have placed higher demands on the functionality, efficiency and reliability of such vehicles. Not only are vehicles required to complete cargo transportation tasks efficiently and safely, but they are also expected to integrate more intelligent functions, such as real-time positioning tracking, remote monitoring, and stable power support for on-board refrigeration equipment and communication equipment. This trend has directly led to a significant increase in the load on the vehicle's electrical system, especially for refrigerated trucks that need to maintain a specific temperature environment, the power demand has increased significantly.

[0003] In this context, the power supply system of light commercial vehicles faces unprecedented challenges. Traditionally, such vehicles rely on the generator attached to the engine body to charge the vehicle's electrical system and battery to ensure that the vehicle can operate normally under various working conditions. However, with the expansion of vehicle functions and the surge in power demand, the original power generation system has gradually become incapable of meeting the needs. Especially under extreme power conditions, such as long-term driving on congested urban roads or performing long-distance refrigerated transportation tasks, if the output current of the generator attached to the engine body is small (for example, the output current of the refrigerated truck generator is less than 60A), it is difficult to meet the power demand of all electrical equipment in the vehicle, resulting in the battery being frequently in a state of power loss. In the long run, this will not only seriously damage the service life of the battery, shorten its replacement cycle, and increase operating costs, but may also cause the vehicle to be unable to start due to exhaustion at a critical moment, affecting the smooth completion of the transportation task, and causing economic losses and reputation damage to customers.

[0004] Furthermore, due to the compact layout of LCVs, designers often face strict physical space constraints when optimizing vehicle performance and cargo space, which means that it is not practical to simply replace the generator with a larger one without changing the overall layout of the vehicle and sacrificing cargo capacity.

[0046] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. 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 making creative work are within the scope of protection of the present application.

[0047] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0048] Figure 1 A flowchart of a method for automatically replenishing battery power provided in an embodiment of the present application.

[0049] The analysis method involved in the embodiments of the present application can be implemented by a terminal device or a server, and the present application does not impose any special restrictions on this. For the convenience of understanding and description, the following embodiments are described in detail by taking a server as an example.

[0050] It should be noted that the server may be a single device or a system consisting of multiple devices, that is, a distributed server, and this application does not make any specific limitation on this.

[0051] like Figure 1 As shown, a method for automatically replenishing battery power provided by an embodiment of the present application includes:

[0052] 101. Monitor the battery power to determine whether the battery power continues to drop to a power threshold.

[0053] Specifically, in one embodiment of the present application, the battery power is monitored to determine whether the battery power continues to drop to a power threshold, specifically including:

[0054] The battery voltage of the vehicle is monitored in real time through the detection device, and the real-time monitoring data is sent to the controller;

[0055] The controller determines whether the battery voltage continues to drop to the warning voltage based on the real-time monitoring data;

[0056] When it is determined based on the battery voltage that the battery power is not less than the power threshold, it is determined that the battery power is in a safe range, and the supplementary power generator is controlled not to start.

[0057] In one embodiment, in a specific vehicle power management system, a method for real-time monitoring of the battery voltage of the vehicle through a detection device is implemented. The system includes a high-precision voltage detection device, which is installed between the positive and negative poles of the vehicle battery to capture the voltage changes of the battery in real time. The detection device measures the battery voltage at regular time intervals (such as every second or every few minutes) through a built-in sensor, and sends these real-time monitoring data to the central controller of the vehicle through a data line or wireless transmission.

[0058] After receiving these voltage data, the central controller will immediately process and analyze them. There is a preset warning voltage value in the controller, which is set according to the specifications and performance of the battery and the use requirements of the vehicle. The controller will determine whether the real-time monitored battery voltage continues to drop to close to or below this warning voltage value. If the voltage remains stable or higher than the warning voltage, the controller will determine that the battery power is within the safe range and will not start the power generator at this time to avoid unnecessary energy consumption and engine burden.

[0059] For example, during a long-distance trip, the vehicle's battery voltage remained above 12.5 V, while the preset warning voltage was 11.8 V. The central controller determined that the battery was fully charged based on real-time monitoring data, so the power generator remained off throughout the trip, ensuring efficient operation and fuel economy of the vehicle.

[0060] In one embodiment of the present application, the battery power is monitored to determine whether the battery power continues to drop to a power threshold, and further includes:

[0061] The supplementary power generator is arranged on the driving shaft at the rear end of the fan of the vehicle engine, and the vehicle engine and the supplementary power generator are connected through a line; the vehicle engine, the rotor and the supplementary power generator are coaxial.

[0062] 102. If so, monitor the operating status of the vehicle engine to determine whether the engine operating status affects the power of the entire vehicle.

[0063] Specifically, in one embodiment of the present application, if yes, the running state of the vehicle engine is monitored to determine whether the running state of the engine affects the power of the whole vehicle, specifically including:

[0064] When the battery power is lower than the power threshold, it is determined that the battery power is in a risk range and the operating state of the vehicle engine is monitored;

[0065] If the engine is in an idle, low-power or low-torque operating condition, it is determined that the engine operating state does not affect the power of the entire vehicle. If the engine is in a high-power or high-torque output condition, it is determined that the engine operating state affects the power of the entire vehicle.

[0066] In one embodiment, in a hybrid vehicle equipped with an advanced power management system, precise monitoring and control of battery power and engine operating status are achieved. The system integrates a power monitoring module, an engine status monitoring module, and a central control unit to implement an intelligent power replenishment strategy.

[0067] In a city driving scenario, the vehicle is driving in a congested traffic environment, starting and stopping frequently. The system's power monitoring module uses high-precision voltage and current sensors to monitor the battery power changes in real time and compares it with the preset power threshold. When the battery power is detected to be lower than the power threshold, the system immediately determines that the battery power is in the risk range and triggers the monitoring of the vehicle engine operating status.

[0068] At this time, the engine status monitoring module obtains the engine's operating parameters in real time, including speed, power output, and torque, through sensors connected to the engine. The system analyzes these parameters to determine the current working state of the engine. For example, in congested road conditions, the engine is often in an idle state, or only outputs low power or low torque to keep the vehicle moving slowly. In this case, the system determines that the engine's operating state will not significantly affect the vehicle's power output, because the vehicle itself has a low demand for power.

[0069] Based on this judgment, the central control unit decides to start the supplementary generator and choose to run it at the highest gear to quickly and efficiently replenish the battery power. The supplementary generator is connected to the battery through the power conversion device inside the vehicle, and the generated electricity is transmitted to the battery, thereby ensuring that the battery power can quickly return to a safe range.

[0070] On the contrary, if in another driving scenario, such as when the vehicle is accelerating to overtake on the highway, and the engine is in a high-power or high-torque output condition, the system will detect this situation and determine that the engine operating state has a significant impact on the power of the entire vehicle. At this time, the system will not immediately start the supplementary power generator at the highest gear, but will first issue a low-battery warning to remind the driver to pay attention to the battery status and may suggest reducing the vehicle's power demand. Subsequently, the system will control the supplementary power generator to start at a low gear and supplement power with a smaller power output to ensure that the battery power is gradually replenished without affecting the power of the entire vehicle.

[0071] 103. When the engine operation status does not affect the power of the whole vehicle, control the supplementary power generator to start at the highest gear for automatic supplementary power.

[0072] Specifically, in one embodiment of the present application, when the engine operation state does not affect the power of the entire vehicle, controlling the power supplement generator to start at the highest gear to automatically supplement power specifically includes:

[0073] When the engine running state does not affect the power of the whole vehicle, the controller controls the clutch to engage, so as to control the supplementary power generator to start at the highest gear;

[0074] The power generated by the power replenishment engine is replenished into the battery, and the battery power is monitored until the battery power reaches the safe power threshold;

[0075] The clutch is controlled to disengage to shut down the supplementary power engine and to supply power to the vehicle through the vehicle engine.

[0076] In one embodiment, when a vehicle is driving on a city road, the battery power gradually decreases due to frequent starting and stopping. The power monitoring module of the system continuously monitors the voltage and current of the battery. When it is found that the power is lower than the preset power threshold, it immediately sends a signal to the central controller to indicate that the battery power has entered the risk range.

[0077] After receiving the signal, the central controller immediately starts monitoring the engine's operating status. Through the engine status sensor, the controller obtains that the engine is currently in an idle state, with low power output and torque, which does not affect the power of the vehicle. Based on this judgment, the controller decides to start the charging process.

[0078] First, the controller sends a command to the clutch control system to engage the clutch and connect the power generator to the vehicle's transmission system. Then, the controller controls the power generator to start at the highest gear, which means that the generator will generate electricity at the maximum efficiency and quickly replenish the battery.

[0079] After the power-supply generator is started, the generated electricity is transmitted to the battery through the power conversion device. At the same time, the power monitoring module of the system continues to monitor the battery in real time to ensure the safety and effectiveness of the power-supply process. When it is detected that the battery power reaches or exceeds the preset safety power threshold, the controller immediately sends a command to the clutch control system to disengage the clutch and disconnect the power-supply generator from the vehicle transmission system.

[0080] After the clutch is disengaged, the power generator stops working and the vehicle resumes the mode of being directly powered by the engine. At this time, the engine not only provides power for the vehicle, but also provides charging current to the battery through the vehicle's power conversion device to maintain the battery charge, ensuring that the battery charge remains within a safe range.

[0081] In one embodiment of the present application, it also includes:

[0082] During the operation of the power supply generator, the working state parameters of the power supply generator are monitored in real time by sensors, and the working state parameters are compared with preset parameter thresholds; the working state parameters include speed, temperature, current and voltage;

[0083] If the working state parameters exceed the normal working parameter range, it is determined that the supplementary power generator is faulty and a fault warning signal is issued;

[0084] According to the severity of the fault, the operating status of the supplementary power generator is adjusted and switched to the backup power supply.

[0085] In one embodiment, the vehicle is driving steadily on the highway, and the battery power is low. The system determines that the supplementary generator can be started to supplement the power according to the engine operation status. After the supplementary generator is started, its working state parameters (including speed, temperature, current and voltage) are monitored in real time by sensors in the system, and these data are transmitted to the central controller in real time.

[0086] After receiving these data, the central controller immediately compares them with the preset working parameter thresholds. These preset parameter thresholds are set based on the specifications, performance and long-term operating experience of the supplementary power generator, and are used to define the parameter range for the normal operation of the supplementary power generator.

[0087] After the power generator has been running for a period of time, the system detects that the temperature of the power generator has suddenly increased abnormally, exceeding the preset temperature threshold. This abnormal change is immediately recognized by the central controller, and it is determined that the power generator may be faulty. In order to ensure the safe operation of the vehicle, the system immediately issues a fault warning signal and alerts the driver through the indicator light and buzzer on the vehicle dashboard.

[0088] At the same time, the central controller quickly adjusts the operating status of the power generator according to the severity of the fault. In the case of abnormal temperature, the system first tries to reduce the load of the power generator to reduce its heat generation. However, if the temperature continues to rise, the system will decisively switch to the backup power supply to ensure the stable operation of the vehicle's power system.

[0089] The backup power source may be another set of batteries built into the vehicle, or other available power sources connected to the vehicle's electrical system. After switching to the backup power source, the system will continue to provide power support to the vehicle, and the central controller will record the fault information of the power generator for subsequent troubleshooting and repair.

[0090] 104. When the engine operating status affects the power of the entire vehicle, a low battery warning is issued, and the power replenishment generator is controlled to start at a low gear to achieve automatic power replenishment for the vehicle.

[0091] Specifically, in one embodiment of the present application, when the engine operation state affects the power of the whole vehicle, a low battery warning is performed, and the power supplement generator is controlled to start at a low gear to realize automatic power supplement for the vehicle, specifically including:

[0092] Generate vehicle warning information based on the engine operating status, and issue low battery warnings in a preset manner to prompt users to reduce power loss;

[0093] When the engine is in a high-power or high-torque output condition, determine that the supplementary power generator is running at a high gear and affects the power of the entire vehicle, and adjust the supplementary power generator to a low gear to power the vehicle through the engine and the supplementary power generator;

[0094] The electricity generated by the charging engine is replenished into the battery, realizing automatic replenishment of the vehicle battery power.

[0095] In one embodiment, the vehicle is traveling on a mountain road. Due to the complex road conditions, the engine needs to frequently operate at high power or high torque to provide sufficient power. At the same time, the power monitoring module of the system continuously monitors the power state of the battery and finds that the power has gradually dropped below a preset power threshold.

[0096] When the battery level drops below the preset threshold, the system immediately generates a warning message for the vehicle and issues a low-battery warning to the user through the display screen on the vehicle dashboard and the voice prompt system. The warning message includes the current battery level, the estimated remaining mileage, and recommended measures to reduce power loss, such as reducing the use of air conditioning and shutting down non-essential electrical equipment, to extend the battery life.

[0097] At the same time, the system conducts real-time analysis of the engine's operating status. When it detects that the engine is in a high-power or high-torque output condition, the system determines that if the supplementary power generator is running at a high gear, it may further increase the burden on the engine and affect the vehicle's power performance. Therefore, the system intelligently adjusts the supplementary power generator to a low gear to ensure that the battery is provided with an appropriate amount of charging current without affecting the vehicle's power output.

[0098] In the low-gear operation mode, the supplementary generator operates at a lower power output, and the electricity it generates is transmitted to the battery through the power conversion device, realizing automatic replenishment of the vehicle battery. At the same time, the engine continues to serve as the main power source to provide the vehicle with the power required for driving.

[0099] Through this intelligent power and power system management solution, the vehicle can maintain stable power output in low-power conditions while effectively replenishing the battery. This not only improves the vehicle's fuel economy and overall performance, but also enhances the user's perception and control of the vehicle's status, improving driving convenience and safety.

[0100] In one embodiment of the present application, it also includes:

[0101] Obtaining the road condition information and weather forecast of the vehicle, so as to establish a power replenishment demand prediction model based on the vehicle's historical driving data, historical driving habits, road condition information and weather forecast;

[0102] The power consumption and power demand of the battery in the future are predicted through the power replenishment demand prediction model;

[0103] According to the power consumption and power demand, the starting time, operating gear and charging time of the charging generator are dynamically adjusted to achieve battery power management.

[0104] In one embodiment, the vehicle is equipped with a comprehensive information collection system that can obtain real-time information about the road conditions of the vehicle, including road congestion, slope, curves, etc. At the same time, through connection with the Internet, it can obtain real-time weather forecast information, including temperature, humidity, precipitation probability, etc. This information is recorded by the system and used as the basic data for establishing a power replenishment demand prediction model together with the vehicle's historical driving data and historical driving habits.

[0105] The system uses machine learning algorithms to conduct in-depth analysis and mining of these data, identify key factors that affect battery power consumption, and establish a replenishment demand prediction model. This model can predict the battery power consumption and power demand in the future (such as the next few hours or days), providing a scientific basis for battery power management.

[0106] Before a long trip, the driver inputs the destination and estimated departure time through the vehicle's smart terminal. Based on this information, combined with the current road conditions and weather forecast, the system predicts the battery power consumption during the future driving process through the power replenishment demand prediction model. The prediction results show that since the vehicle will pass through multiple mountainous areas in the next few days and the weather forecast shows that there will be rainfall, the battery power consumption will be accelerated.

[0107] Based on this prediction result, the system dynamically adjusts the start-up time, operating gear and charging duration of the power supply generator. Before driving to the mountainous area, the system starts the power supply generator in advance and runs it at a higher gear to quickly replenish the battery power. At the same time, the system also adjusts the operating status of the power supply generator in real time according to changes in road conditions and weather forecasts to ensure that the battery power is always kept within a safe range.

[0108] During the driving process, the system also continuously provides feedback and optimizes the power replenishment demand prediction model based on actual power consumption and road conditions to improve the accuracy and reliability of the prediction. Through this intelligent battery power management strategy, the vehicle successfully completed the long-distance trip, the battery power was always sufficient, and there was no situation where the vehicle could not drive due to power exhaustion.

[0109] The above is an embodiment of the method proposed in this application. Based on the same inventive concept, the embodiment of this application also provides a device for automatically replenishing the battery power, and its structure is as follows: Figure 2 shown.

[0115] If so, the running state of the vehicle engine is monitored to determine whether the running state of the engine affects the power of the whole vehicle;

[0116] When the engine running state does not affect the power of the whole vehicle, the power supplement generator is controlled to start at the highest gear to automatically supplement power;

[0117] When the engine operating status affects the power of the entire vehicle, a low battery warning is issued, and the power replenishment generator is controlled to start at a low gear to achieve automatic power replenishment for the vehicle.
