Description

Technical Field

[0001] This invention relates to the field of battery technology, and more specifically to battery power control methods, devices, electronic devices, media, and program products. Background Technology

[0002] In the automotive industry, electric vehicles are gradually becoming mainstream, with the latest market sales data showing that they account for over 50% of total sales. The power source for most electric vehicles is lithium-ion batteries, which are a relatively new product (less than 40 years old), with automotive lithium-ion batteries being less than 30 years old. Therefore, the performance of lithium-ion batteries is still in a relatively early stage, as evidenced by changes in battery power.

[0003] Changes in battery power result in an inconsistent driving experience for the driver. For example, if the battery power was 80% at the previous traffic light, the driver would need to open the accelerator pedal significantly to start the vehicle at their usual speed. However, if the current traffic light has 100% power, the driver might accelerate too quickly or even cause a safety hazard if they follow the same method as at the previous traffic light. Conversely, when overtaking on a road without a center line, if the battery power was 100% in the previous overtaking maneuver, it would allow for easy acceleration and overtaking. However, if the current overtaking maneuver has only 80% power, the driver might not be able to accelerate quickly enough and complete the overtaking maneuver within the expected time, potentially leading to an accident with oncoming traffic.

[0004] Therefore, power consistency and linearity are particularly important. Consequently, controlling the battery's output power has become a pressing issue. Summary of the Invention

[0005] In view of this, the present invention provides a battery power control method, device, electronic device, medium, and program product to solve the problem of how to control the output power of a battery.

[0006] In a first aspect, the present invention provides a battery power control method, the method comprising:

[0007] Obtain the current vehicle status of the target vehicle;

[0008] Based on the current vehicle status of the target vehicle, determine the output power limit level corresponding to the target battery in the target vehicle;

[0009] The output power of the target battery is controlled according to the output power limit level corresponding to the target battery.

[0010] The battery power control method provided in this application obtains the current vehicle state of the target vehicle; based on the current vehicle state, it determines the output power limit level corresponding to the target battery in the target vehicle, ensuring the accuracy of the determined output power limit level. Then, based on the output power limit level corresponding to the target battery, it controls the output power of the target battery, thereby ensuring acceleration performance while maintaining normal vehicle operation, meeting the short-term high power output requirements of the target battery in emergencies, and ensuring consistent and smooth driver operation, further improving the comfort and safety of the target vehicle.

[0011] In one optional implementation, the current vehicle state includes the current vehicle speed. Based on the current vehicle state of the target vehicle, the output power limitation level corresponding to the target battery in the target vehicle is determined, including:

[0012] Compare the current vehicle speed with the first preset vehicle speed threshold;

[0013] If the current vehicle speed is less than the first preset vehicle speed threshold, the output power limit level corresponding to the target battery is determined to be the second level, and the second level information is output to the driver.

[0014] The battery power control method provided in this application compares the current vehicle speed with a first preset vehicle speed threshold. If the current vehicle speed is less than the first preset vehicle speed threshold, the output power limit level corresponding to the target battery is determined to be a second level, and the second level information is output to the driver. This ensures the accuracy of determining the output power limit level corresponding to the target battery as the second level, thereby satisfying the target vehicle's acceleration performance while maintaining normal driving, and ensuring the consistency and smoothness of the driver's operation, further improving the comfort and safety of the target vehicle. Furthermore, it allows the driver to obtain the current output power limit level corresponding to the target vehicle.

[0015] In one optional implementation, determining the output power limitation level corresponding to the target battery in the target vehicle based on the current vehicle status further includes:

[0016] If the current vehicle speed is greater than the first preset vehicle speed threshold, compare the current vehicle speed with the second preset vehicle speed threshold; the second preset vehicle speed threshold is greater than the first preset vehicle speed threshold.

[0017] If the current vehicle speed is less than the second preset vehicle speed threshold, then the output power limit level corresponding to the target battery is determined to be the second level.

[0018] The battery power control method provided in this application compares the current vehicle speed with a second preset vehicle speed threshold if the current vehicle speed is greater than a first preset vehicle speed threshold; if the current vehicle speed is less than the second preset vehicle speed threshold, the output power limit level corresponding to the target battery is determined to be the second level. This ensures the accuracy of determining the output power limit level corresponding to the target battery to be the second level, thereby satisfying the target vehicle's acceleration performance while driving normally, and ensuring the consistency and smoothness of the driver's operation, further improving the comfort and safety of the target vehicle. Furthermore, it allows the driver to obtain the current output power limit level corresponding to the target vehicle.

[0019] In one optional implementation, determining the output power limitation level corresponding to the target battery in the target vehicle based on the current vehicle status further includes:

[0020] Record the duration during which the current vehicle speed is greater than the first preset vehicle speed threshold and less than the second preset vehicle speed threshold;

[0021] If the duration exceeds the preset duration, the output power limit level corresponding to the target battery in the target vehicle is switched from the second level to the third level, and the third level information is output to the driver; wherein, the third maximum limit power corresponding to the third level is less than the second maximum limit power corresponding to the second level;

[0022] When preset conditions are met, the output power limit level corresponding to the target battery is switched from level three to level two.

[0023] The battery power control method provided in this application records the duration for which the current vehicle speed is greater than a first preset vehicle speed threshold and less than a second preset vehicle speed threshold, thereby accurately obtaining the duration for which the target vehicle operates at a higher current speed. If the duration exceeds the preset duration, the output power limit level corresponding to the target battery in the target vehicle is switched from the second level to the third level, and the third level information is output to the driver. This allows for the satisfaction of the target vehicle's acceleration performance while ensuring the driving safety of the target vehicle and the safety of the target battery. When preset conditions are met, the output power limit level corresponding to the target battery is switched from the third level to the second level, thereby satisfying normal acceleration requirements.

[0024] In one optional implementation, the current vehicle status includes an emergency state. Obtaining the current vehicle status of the target vehicle includes:

[0025] Obtain the accelerator pedal opening and / or steering wheel angle corresponding to the target vehicle;

[0026] If the accelerator pedal opening is greater than the preset accelerator pedal opening and / or the steering wheel angle is greater than the preset steering wheel angle, then the driver's driving action will be identified.

[0027] If the driver's driving actions meet the preset requirements, the current vehicle status of the target vehicle is determined to be an emergency state.

[0028] Correspondingly, based on the current vehicle status of the target vehicle, the output power limitation level corresponding to the target battery in the target vehicle is determined, including:

[0029] Based on the fact that the target vehicle is currently in an emergency state, the output power limitation level corresponding to the target battery is determined to be Level 1.

[0030] The battery power control method provided in this application obtains the accelerator pedal opening and / or steering wheel angle corresponding to the target vehicle. If the accelerator pedal opening is greater than a preset accelerator pedal opening and / or the steering wheel angle is greater than a preset steering wheel angle, the driver's driving action is identified. If the driver's driving action meets preset requirements, the current vehicle state of the target vehicle is determined to be an emergency state, ensuring the accuracy of determining the current vehicle state as an emergency state and avoiding false triggering by a single condition. Based on the current vehicle state of the target vehicle being an emergency state, the output power limit level corresponding to the target battery is determined to be the first level, thereby meeting the short-term high power output of the target battery in an emergency, thus ensuring the safe driving of the target vehicle, while also ensuring the consistency and smoothness of the driver's operation, further improving the comfort and safety of the target vehicle.

[0031] In one optional implementation, the output power of the target battery is controlled according to the output power limitation level corresponding to the target battery, including:

[0032] Detect whether the target battery meets the switching conditions for switching to the first level, and output the detection result;

[0033] If the target battery meets the switching conditions for switching to the first level, then obtain the first maximum power limit corresponding to the first level;

[0034] Based on the first maximum power limit, the output power of the target battery is controlled, and the first level information is output to the driver;

[0035] After a preset duration, the output power limit level corresponding to the target battery is switched from the first level to the second level; wherein, the second maximum limit power corresponding to the second level is less than the first maximum limit power.

[0036] The battery power control method provided in this application detects whether the target battery meets the switching conditions for switching to the first level and outputs the detection result. This ensures the accuracy of the detection result and allows the driver to understand whether the target battery currently meets the switching conditions for switching to the first level. If the target battery meets the switching conditions for switching to the first level, the electronic device determines that the output power limit level corresponding to the target battery can be switched to the first level. Then, the first maximum limit power corresponding to the first level is obtained, and the output power of the target battery is controlled according to the first maximum limit power. The first level information is then output to the driver, ensuring the accuracy of the determined first maximum limit power and allowing the driver to obtain the current output power limit level corresponding to the target battery. After a preset time, the output power limit level corresponding to the target battery is controlled to switch from the first level to the second level, which can reduce the power consumption of the target battery and ensure the normal operation of the target battery. If the target battery does not meet the switching conditions for switching to the first level, the waiting time for the target battery to meet the switching conditions for switching to the first level is calculated and output, so that the driver can understand the waiting time for the target battery to meet the switching conditions for switching to the first level.

[0037] In one optional implementation, detecting whether the target battery meets the switching conditions for switching to the first level includes:

[0038] Detect whether the remaining power of the target battery is greater than a preset remaining power threshold;

[0039] and / or

[0040] Detect whether the target battery is malfunctioning;

[0041] and / or

[0042] Obtain the historical time when the target battery last switched to the first level;

[0043] Calculate the time interval between historical time and the current time;

[0044] Check if the time interval is greater than the preset time interval duration.

[0045] The battery power control method provided in this application embodiment detects whether the remaining power of the target battery is greater than a preset remaining power threshold, ensuring the accuracy of the detection results. Based on the detection results, it can then determine whether the remaining power of the target battery supports switching to the first level. And / or, it detects whether the target battery has malfunctioned, thereby determining whether the target battery's state meets the requirements for switching to the first level based on the detection results. And / or, it obtains the historical time of the target battery's last switch to the first level; calculates the time interval between the historical time and the current time, ensuring the accuracy of the calculated time interval. It also detects whether the time interval is greater than a preset time interval duration, ensuring the accuracy of the detection results.

[0046] In a second aspect, the present invention provides a battery power control device, the device comprising:

[0047] The acquisition module is used to acquire the current vehicle status of the target vehicle;

[0048] The determination module is used to determine the output power limit level corresponding to the target battery in the target vehicle based on the current vehicle status.

[0049] The control module is used to control the output power of the target battery according to the output power limit level corresponding to the target battery.

[0050] The battery power control device provided in this application embodiment acquires the current vehicle state of the target vehicle; based on the current vehicle state, it determines the output power limit level corresponding to the target battery in the target vehicle, ensuring the accuracy of the determined output power limit level. Then, based on the output power limit level corresponding to the target battery, it controls the output power of the target battery, thereby satisfying the target vehicle's acceleration performance during normal driving, while also meeting the short-term high power output requirements of the target battery in emergencies. Simultaneously, it ensures the consistency and smoothness of the driver's operation, further improving the comfort and safety of the target vehicle.

[0051] Thirdly, the present invention provides an electronic device, comprising: a memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the computer instructions to perform the battery power control method of the first aspect or any corresponding embodiment described above.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0061] In the automotive industry, electric vehicles are gradually becoming mainstream, and the latest market sales data shows that electric vehicle sales account for more than 50%. The power source of electric vehicles is mostly lithium-ion batteries, which are a product that has been around for less than 40 years, and automotive lithium-ion batteries are even less than 30 years old. The performance of lithium-ion batteries is still in a relatively early stage, requiring suitable operating temperature, good depth of charge and discharge, and limited charge and discharge power.

[0062] The first point can be controlled through thermal management, the second through BMS management, and the third, until significant breakthroughs are made in battery technology, BMS strategies generally involve setting different power levels for different durations to meet the vehicle's power demands. This is known in the industry as SOP (Start of Production) scheduling.

[0063] However, the timing-switching strategy has a significant problem: the power output changes, resulting in an inconsistent driving experience for the driver. For example, if the previous traffic light had a power output of 80%, the driver would need to open the accelerator pedal quite far to get the vehicle moving at the usual speed. But if the current traffic light has a power output of 100%, and the driver operates the accelerator pedal as they did at the previous traffic light, it could lead to excessive acceleration or even safety issues.

[0064] Conversely, if you are overtaking on a road without a center line, and your power was 100% last time you overtook, you could easily accelerate and overtake. However, if your power is only 80% this time, you may not be able to accelerate quickly enough and may not be able to complete the overtaking within the expected time, potentially leading to an accident with oncoming vehicles.

[0065] Therefore, power consistency and linearity are particularly important. Additionally, in emergency situations, such as avoiding accidents or obstacles, rapid acceleration in a short time is required, necessitating corresponding capabilities from both the vehicle and the battery.

[0066] Therefore, how to control the output power of the battery has become an urgent problem to be solved.

[0067] To address the aforementioned issues, this application provides a battery power control method that acquires the current vehicle state of a target vehicle; based on the current vehicle state, it determines the output power limit level corresponding to the target battery in the target vehicle, ensuring the accuracy of the determined output power limit level. Then, based on the output power limit level corresponding to the target battery, it controls the output power of the target battery, thereby ensuring acceleration performance during normal driving, meeting the short-term high-power output requirements of the target battery in emergencies, and guaranteeing consistent and smooth driver operation, further improving the comfort and safety of the target vehicle.

[0068] It should be noted that the battery power control method provided in this application can be executed by a battery power control device. This device can be implemented as part or all of an electronic device through software, hardware, or a combination of both. The electronic device can be a control device in the target vehicle. In the following method embodiments, the execution subject is always described using an electronic device as an example.

[0069] According to an embodiment of the present invention, a battery power control method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0070] This embodiment provides a battery power control method, which can be used in the aforementioned electronic device. Figure 1 This is a flowchart of a battery power control method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0071] Step S101: Obtain the current vehicle status of the target vehicle.

[0072] The current vehicle status includes: first stable operating status, second stable operating status, and emergency status.

[0073] The first stable operating state refers to the state where the target vehicle's current speed is less than the first preset speed threshold; the second stable operating state refers to the state where the target vehicle's current speed is greater than the first preset speed threshold but less than the second preset speed threshold. The second preset speed threshold is greater than the first preset speed threshold; the emergency state refers to the state where the target vehicle encounters an emergency situation and needs to accelerate or brake suddenly, and / or turn the steering wheel sharply.

[0074] Optionally, the electronic device can monitor the current speed of the target vehicle using a vehicle speed sensor. Then, based on the target vehicle's current speed, the electronic device determines the current vehicle state of the target vehicle.

[0075] Optionally, the electronic device can also acquire the accelerator pedal opening of the target vehicle, and then determine the current vehicle state of the target vehicle based on the accelerator pedal opening of the target vehicle.

[0076] Optionally, the electronic device can also acquire the brake opening of the target vehicle and then determine the current vehicle status of the target vehicle based on the brake opening of the target vehicle.

[0077] Optionally, the electronic device can also acquire the steering wheel angle corresponding to the target vehicle, and then determine the current vehicle state of the target vehicle based on the steering wheel angle.

[0078] This application does not specifically limit the method by which the electronic device obtains the current vehicle status of the target vehicle.

[0079] Step S102: Determine the output power limitation level corresponding to the target battery in the target vehicle based on the current vehicle status.

[0080] Specifically, electronic devices can determine the output power limit level of the target battery in the target vehicle based on the correspondence between the current vehicle status and the output power limit level of the target vehicle.

[0081] For example, when the target vehicle is in a stable operating state, it operates at low speed and does not need to control the target battery power to 100%. Controlling the target battery power to 80% may suffice to meet the vehicle's overtaking and acceleration needs. However, when the target vehicle is in an emergency operating state, the target battery power must be controlled to 100% to prevent dangerous situations. Therefore, the electronic device determines the output power limit level for the target battery based on the correspondence between the target vehicle's current operating state and the output power limit level. This helps prevent dangerous situations from occurring.

[0082] This step will be explained in detail below.

[0083] Step S103: Control the output power of the target battery according to the output power limit level corresponding to the target battery.

[0084] Specifically, the electronic device can determine the maximum power limit corresponding to the output power limit level of the target battery based on the output power limit level of the target battery. Then, it controls the output power of the target battery according to the maximum power limit corresponding to the target battery.

[0085] The battery power control method provided in this application obtains the current vehicle state of the target vehicle; based on the current vehicle state, it determines the output power limit level corresponding to the target battery in the target vehicle, ensuring the accuracy of the determined output power limit level. Then, based on the output power limit level corresponding to the target battery, it controls the output power of the target battery. When the target vehicle is running smoothly, the output power of the target vehicle can be controlled to be lower, only needing to meet the acceleration performance of the target vehicle. This not only ensures acceleration performance while driving normally, but also reduces the power consumption of the target battery. When the target vehicle is in an emergency, the output power of the target vehicle can be controlled to be higher. This allows the target battery to output high power for a short time in an emergency, while ensuring the consistency and smoothness of the driver's operation. It avoids situations where the target vehicle is in an emergency but the maximum power limit of the target battery is too low, thus failing to support the target vehicle in handling the emergency and leading to danger. Therefore, the above method further improves the comfort and safety of the target vehicle.

[0086] This embodiment provides a battery power control method, which can be used in the aforementioned electronic device. Figure 2 This is a flowchart of a battery power control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0087] Step S201: Obtain the current vehicle status of the target vehicle.

[0088] Please refer to the above description of step S101 for details on this step, which will not be repeated here.

[0089] Step S202: Determine the output power limitation level corresponding to the target battery in the target vehicle based on the current vehicle status of the target vehicle.

[0090] In one optional embodiment of this application, the current vehicle state includes the current vehicle speed, and step S202 above may include the following steps:

[0091] Step S2021: Compare the current vehicle speed with the first preset vehicle speed threshold.

[0092] Specifically, the electronic device can receive a first preset vehicle speed threshold input by the user, or it can receive a first preset vehicle speed threshold sent by other devices. The electronic device can also determine the first preset vehicle speed threshold based on the attribute information corresponding to the target vehicle. For example, the electronic device can set the first preset vehicle speed threshold corresponding to the target vehicle based on attribute information such as the target vehicle's model, weight, and tire condition.

[0093] This application does not specifically limit the method by which the electronic device obtains the first preset vehicle speed threshold.

[0094] After obtaining the first preset vehicle speed threshold, the electronic device can compare the current vehicle speed with the first preset vehicle speed threshold.

[0095] In step S2022, if the current vehicle speed is less than the first preset vehicle speed threshold, the output power limit level corresponding to the target battery is determined to be the second level, and the second level information is output to the driver.

[0096] Specifically, if the current vehicle speed is less than a first preset speed threshold, the electronic device can determine that the output power limitation level corresponding to the target battery is Level 2. Then, the electronic device can display the Level 2 information to the driver through the instrument panel or display screen.

[0097] It should be noted that the target vehicle is currently in its first stable operating state, with a low speed and the potential for emergency situations. Therefore, to ensure the vehicle can accelerate and overtake at any time, and to handle emergency acceleration or braking, the output power limit level for the target battery is set to Level 2. This satisfies the vehicle's acceleration performance requirements, and allows for a quick switch from Level 2 to Level 1 in case of an emergency, enabling the vehicle to respond appropriately.

[0098] In one optional embodiment of this application, step S202 may further include the following steps:

[0099] Step S2023: If the current vehicle speed is greater than the first preset vehicle speed threshold, compare the current vehicle speed with the second preset vehicle speed threshold.

[0100] The second preset vehicle speed threshold is greater than the first preset vehicle speed threshold.

[0101] Specifically, the electronic device can receive a second preset vehicle speed threshold input by the user, or it can receive a second preset vehicle speed threshold sent by other devices. The electronic device can also determine the second preset vehicle speed threshold based on the attribute information corresponding to the target vehicle. For example, the electronic device can set the second preset vehicle speed threshold corresponding to the target vehicle based on attribute information such as the target vehicle's model, weight, and tire condition. This application embodiment does not specifically limit the method by which the electronic device obtains the second preset vehicle speed threshold.

[0102] Specifically, if the current vehicle speed is greater than the first preset vehicle speed threshold, the electronic device can compare the current vehicle speed with the acquired second preset vehicle speed threshold.

[0103] Step S2024: If the current vehicle speed is less than the second preset vehicle speed threshold, then the output power limit level corresponding to the target battery is determined to be the second level.

[0104] Specifically, if the current vehicle speed is less than the second preset vehicle speed threshold, the electronic device can determine that the output power limit level corresponding to the target battery is the second level.

[0105] It should be noted that the target vehicle is currently in the second stable operating state, with a relatively high speed and the potential for emergency situations. Therefore, the primary requirement is to meet the target vehicle's driving needs for stable operation at high speeds. Furthermore, it is necessary to ensure the target vehicle can handle emergency situations such as sudden acceleration or braking. Therefore, the output power limit level corresponding to the target battery is controlled at level two. This satisfies the target vehicle's high-speed stable operating state, and facilitates switching the output power limit level of the target battery from level two to level one when the target vehicle encounters an emergency, enabling the target vehicle to cope with the emergency.

[0106] In one optional embodiment of this application, step S202 may further include the following steps:

[0107] Step S2025: Record the duration during which the current vehicle speed is greater than the first preset vehicle speed threshold and less than the second preset vehicle speed threshold.

[0108] Specifically, when it is determined that the current vehicle speed is greater than the first preset vehicle speed threshold and less than the second preset vehicle speed threshold, the electronic device can record the duration for which the current vehicle speed is greater than the first preset vehicle speed threshold and less than the second preset vehicle speed threshold.

[0109] In step S2026, if the duration exceeds the preset duration, the output power limit level corresponding to the target battery in the target vehicle is switched from the second level to the third level, and the third level information is output to the driver.

[0110] Among them, the third maximum power limit corresponding to the third level is less than the second maximum power limit corresponding to the second level.

[0111] Specifically, the electronic device can receive a preset duration input by the user or a preset duration sent by other devices. It can also set a preset duration corresponding to the target vehicle's minimum acceleration requirement time. For example, the preset duration corresponding to the target vehicle can be more than twice the minimum acceleration requirement time, such as 30 seconds, to meet most operating conditions.

[0112] This application does not specifically limit the method by which the electronic device obtains the preset duration.

[0113] The electronic device then compares the duration with a preset duration. If the duration is longer than the preset duration, the electronic device can switch the output power limit level corresponding to the target battery in the target vehicle from level two to level three. The electronic device can then display the level three information to the driver via the instrument panel or display screen.

[0114] Step S2027: When the preset conditions are met, control the output power limit level corresponding to the target battery to switch from the third level to the second level.

[0115] Optionally, after the electronic device switches the output power limit level corresponding to the target battery in the target vehicle from level two to level three, if the current vehicle speed of the target vehicle is less than a first preset vehicle speed threshold, the electronic device determines that the current vehicle speed is low. The electronic device determines that the current vehicle state of the target vehicle is in a first stable operating state. In order to meet the driving needs of the target vehicle such as overtaking and acceleration, it is necessary to switch the output power limit level corresponding to the target battery from level three to level two.

[0116] Optionally, after the electronic device switches the output power limit level corresponding to the target battery in the target vehicle from the second level to the third level, after a preset time, in order to meet the driving needs of the target vehicle such as overtaking and acceleration, it is necessary to switch the output power limit level corresponding to the target battery from the third level back to the second level.

[0117] Step S203: Control the output power of the target battery according to the output power limit level corresponding to the target battery.

[0118] Please refer to the above description of step S103 for details on this step, which will not be repeated here.

[0119] The battery power control method provided in this application compares the current vehicle speed with a first preset vehicle speed threshold. If the current vehicle speed is less than the first preset vehicle speed threshold, the output power limit level corresponding to the target battery is determined to be a second level, and the second level information is output to the driver. This allows the target vehicle to maintain acceleration performance while driving at low speeds, while also ensuring the consistency and smoothness of the driver's operation, further improving the comfort and safety of the target vehicle. Furthermore, it allows the driver to obtain the current output power limit level corresponding to the target vehicle.

[0120] If the current vehicle speed exceeds a first preset speed threshold, it is compared with a second preset speed threshold. If the current speed is less than the second preset speed threshold, the output power limit level corresponding to the target battery is determined to be Level 2. This ensures that the target vehicle maintains acceleration performance during normal driving, while also guaranteeing consistent and smooth driver operation, further enhancing the comfort and safety of the target vehicle. Furthermore, it allows the driver to obtain the current output power limit level corresponding to the target vehicle.

[0121] Furthermore, the electronic device records the duration for which the current vehicle speed is greater than a first preset speed threshold but less than a second preset speed threshold, thus accurately determining the duration for which the target vehicle operates at a relatively high current speed. If the duration exceeds the preset duration, indicating that the vehicle is in a stable high-speed driving state, the output power limit level corresponding to the target battery in the target vehicle is switched from level two to level three, and level three information is output to the driver. This ensures the driving safety of the target vehicle and the safety of the target battery. When preset conditions are met, the output power limit level corresponding to the target battery is switched from level three to level two, thereby meeting acceleration requirements and the needs for handling emergency situations in the future.

[0122] This embodiment provides a battery power control method, which can be used in the aforementioned electronic device. Figure 3 This is a flowchart of a battery power control method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:

[0123] Step S301: Obtain the current vehicle status of the target vehicle.

[0124] In one optional embodiment of this application, the current vehicle state includes an emergency state. The emergency state may include an emergency acceleration state, an emergency deceleration state, and an emergency turning state. Step S301 above may include the following steps:

[0125] Step S3011: Obtain the accelerator pedal opening and / or steering wheel angle corresponding to the target vehicle.

[0126] Specifically, the electronic equipment can monitor the accelerator pedal of the target vehicle to determine its opening. It can also monitor the steering wheel of the target vehicle to determine its steering angle.

[0127] In step S3012, if the accelerator pedal opening is greater than the preset accelerator pedal opening and / or the steering wheel angle is greater than the preset steering wheel angle, then the driver's driving action is identified.

[0128] Specifically, the electronic device can receive preset accelerator pedal opening and preset steering wheel angle input by the user, or it can receive preset accelerator pedal opening and preset steering wheel angle sent by other devices. This application embodiment does not specifically limit the method by which the electronic device obtains the preset accelerator pedal opening and preset steering wheel angle.

[0129] The electronic device can then compare the accelerator pedal opening with a preset accelerator pedal opening, and / or compare the steering wheel angle with a preset steering wheel angle.

[0130] If the accelerator pedal opening is greater than the preset accelerator pedal opening and / or the steering wheel angle is greater than the preset steering wheel angle, the electronic device can capture the driver's driving actions based on the camera device. Then, the electronic device can identify the corresponding driving action image of the driver to determine the corresponding driving action of the driver.

[0131] Step S3013: If the driver's driving actions meet the preset requirements, then the current vehicle status of the target vehicle is determined to be an emergency state.

[0132] Specifically, electronic devices can detect whether the driver's driving actions meet preset requirements. These preset requirements could include, for example, the driver gripping the steering wheel firmly.

[0133] If the driver's driving actions meet the preset requirements, the electronic equipment can determine that the target vehicle's current vehicle status is an emergency.

[0134] Step S302: Determine the output power limitation level corresponding to the target battery in the target vehicle based on the current vehicle status of the target vehicle.

[0135] Correspondingly, step S302 above may include the following steps:

[0136] Step S3021: Based on the current vehicle status of the target vehicle being an emergency state, determine the output power limitation level corresponding to the target battery as Level 1.

[0137] Specifically, when the current vehicle status of the target vehicle is an emergency state, the electronic equipment determines the output power limit level of the target battery as Level 1 based on the correspondence between the emergency state and the output power limit level of the target battery.

[0138] Step S303: Control the output power of the target battery according to the output power limit level corresponding to the target battery.

[0139] Specifically, the electronic device can determine the first maximum power limit corresponding to the first level of the target battery, and then control the output power of the target battery according to the first maximum power limit.

[0140] Specifically, step S303 above may include the following steps:

[0141] Step S3031: Detect whether the target battery meets the switching conditions for switching to the first level, and output the detection result.

[0142] Specifically, the step S3031 above, "detecting whether the target battery meets the switching conditions for switching to the first level," may include the following steps:

[0143] Step a1: Detect whether the remaining power of the target battery is greater than the preset remaining power threshold.

[0144] Specifically, the electronic device can monitor the target battery's power level to determine its remaining power. Then, it compares this remaining power level with a preset remaining power threshold. If the remaining power level is greater than or equal to the preset threshold, the target battery meets the switching conditions for the first level. If the remaining power level is less than the preset threshold, the target battery does not meet the switching conditions for the first level.

[0145] and / or

[0146] Step a2: Detect whether the target battery is faulty.

[0147] Optionally, the electronic devices can detect whether the target battery has malfunctioned based on the battery management system (BMS) in the target vehicle. The BMS is an electronic system specifically designed to monitor and manage battery status. It can measure parameters such as voltage, current, and temperature of the target battery in real time and determine whether the target battery is functioning normally based on these parameters. If the BMS detects abnormal voltage, excessive current, or excessive temperature in the target battery, it will issue an alarm or take appropriate measures, such as limiting charging or discharging.

[0148] Optionally, electronic devices can also assess the health status of the target battery by analyzing parameters such as its charge-discharge characteristics and internal resistance.

[0149] Optionally, the electronic device can directly measure the voltage of the target battery. If the target battery voltage is below the normal range, it may indicate that the battery is low on power or is faulty.

[0150] Optionally, the electronic device can directly measure the charging and discharging current of the target battery to determine whether the target battery is working properly. Abnormal current fluctuations or excessively high discharging currents may be signs of target battery malfunction.

[0151] Optionally, the electronic device can monitor the temperature of the target battery; if the temperature is too high or too low, it may indicate a problem with the target battery.

[0152] This application does not specifically limit the method by which electronic devices detect whether a target battery has malfunctioned.

[0153] Specifically, if the target battery does not malfunction, it is determined that the target battery meets the switching conditions for switching to the first level. If the target battery malfunctions, it is determined that the target battery does not meet the switching conditions for switching to the first level.

[0154] and / or

[0155] Step a3: Obtain the historical time when the target battery last switched to the first level.

[0156] Specifically, the electronic device can retrieve the record of the target battery switching to the first level from the storage space, and then query the historical time when the target battery last switched to the first level from the record of the target battery switching to the first level.

[0157] Step a4: Calculate the time interval between the historical time and the current time.

[0158] Specifically, electronic devices can calculate the time interval between the historical time and the current time by subtracting the historical time from the current time.

[0159] Step a5: Check if the time interval is greater than the preset time interval duration.

[0160] Specifically, the electronic device can receive a preset time interval duration input by the user, or it can receive a preset time interval duration sent by other devices. This application embodiment does not specifically limit the method by which the electronic device obtains the preset time interval duration.

[0161] Then, the electronic device can compare the time interval with the preset time interval duration to detect whether the time interval is longer than the preset time interval duration.

[0162] If the time interval is greater than or equal to the preset time interval, the target battery is determined to meet the switching conditions for the first level. If the time interval is less than the preset time interval, the target battery is determined not to meet the switching conditions for the first level.

[0163] Step S3032: If the target battery meets the switching conditions for switching to the first level, then obtain the first maximum power limit corresponding to the first level.

[0164] Specifically, if the target battery meets the switching conditions for switching to the first level, the electronic device determines the first maximum power limit corresponding to the first level based on the correspondence between the output power limit level and the maximum power limit.

[0165] Step S3033: Control the output power of the target battery according to the first maximum power limit, and output the first level information to the driver.

[0166] Specifically, the electronic device can control the output power of the target battery based on the first maximum power limit and output first-level information to the driver.

[0167] Step S3034: After a preset duration, control the output power limit level corresponding to the target battery to switch from the first level to the second level.

[0168] Among them, the second maximum limiting power corresponding to the second level is less than the first maximum limiting power.

[0169] Specifically, after a preset duration, the electronic device can control the output power limit level corresponding to the target battery to switch from the first level to the second level.

[0170] The preset duration can be set according to the time required to handle an emergency. For example, the time required to handle an emergency evacuation can be 5 seconds, so the preset duration can be 5 seconds.

[0171] Step S3035: If the target battery does not meet the switching conditions for switching to the first level, calculate the waiting time for the target battery to meet the switching conditions for switching to the first level and output the waiting time.

[0172] Specifically, if the target battery does not meet the switching conditions for switching to the first level, the electronic device calculates the waiting time for the target battery to meet the switching conditions for switching to the first level and outputs the waiting time.

[0173] Optionally, if the target battery does not meet the switching condition for switching to the first level (i.e., the remaining charge of the target battery is less than a preset remaining charge threshold), the electronic device can estimate the future charging time based on the historical charging time of the target battery. Then, based on the future charging time, it determines the first waiting time for the target battery to meet the switching requirement for the first level.

[0174] Optionally, if the target battery fails to meet the switching conditions for switching to the first level, the electronic device estimates the target battery fault clearance time and determines the second waiting time for the target battery to meet the switching conditions for switching to the first level based on the target battery fault clearance time.

[0175] Optionally, if the target battery does not meet the switching condition for switching to the first level because the time interval is less than the preset time interval, the electronic device calculates the third waiting time for the target battery to meet the switching condition for switching to the first level by subtracting the time interval from the preset time interval.

[0176] The waiting time can be the maximum value among the first waiting time, the second waiting time, and the third waiting time.

[0177] The battery power control method provided in this application obtains the accelerator pedal opening and / or steering wheel angle corresponding to the target vehicle. If the accelerator pedal opening is greater than a preset accelerator pedal opening and / or the steering wheel angle is greater than a preset steering wheel angle, the driver's driving action is identified. If the driver's driving action meets preset requirements, the current vehicle state of the target vehicle is determined to be an emergency state, ensuring the accuracy of determining the current vehicle state as an emergency state and avoiding false triggering by a single condition. Based on the current vehicle state of the target vehicle being an emergency state, the output power limit level corresponding to the target battery is determined to be the first level, thereby meeting the short-term high power output of the target battery in an emergency, thus ensuring the safe driving of the target vehicle, while also ensuring the consistency and smoothness of the driver's operation, further improving the comfort and safety of the target vehicle.

[0178] Then, it checks whether the remaining charge of the target battery is greater than a preset remaining charge threshold. Based on the detection result, it determines whether the remaining charge of the target battery supports switching to the first level. Alternatively, it checks whether the target battery is faulty, and based on the detection result, it determines whether the state of the target battery meets the requirements for switching to the first level. It obtains the historical time when the target battery last switched to the first level; calculates the time interval between the historical time and the current time, and checks whether the time interval is greater than a preset time interval. This avoids the driver frequently controlling the accelerator pedal opening and / or steering wheel angle, thus triggering the switch of the target battery's output power limit level from the second level to the first level. This reduces the target battery's power consumption, ensures the target battery's lifespan, and guarantees driving safety. If the target battery meets the switching conditions for switching to the first level, the electronic device determines that the output power limit level corresponding to the target battery can be switched to the first level. Then, it obtains the first maximum power limit corresponding to the first level, controls the output power of the target battery based on the first maximum power limit, and outputs the first level information to the driver, ensuring the accuracy of the determined first maximum power limit and allowing the driver to obtain the current output power limit level corresponding to the target battery. After a preset duration, the output power limit level corresponding to the target battery is switched from level one to level two, which can reduce the power consumption of the target battery and ensure its normal operation. If the target battery does not meet the switching conditions to level one, the waiting time for the target battery to meet the switching conditions to level one is calculated and output, so that the driver can know the waiting time for the target battery to meet the switching conditions to level one.

If the driver's driving action meets the preset requirements, the current vehicle state of the target vehicle is determined to be an emergency state.

[0189] In some optional implementations, the control module 403 is specifically used to detect whether the remaining power of the target battery is greater than a preset remaining power threshold; and / or detect whether the target battery has malfunctioned; and / or obtain the historical time when the target battery last switched to the first level; calculate the time interval between the historical time and the current time; and detect whether the time interval is greater than a preset time interval duration.
