Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery power preservation method, electronic equipment, storage medium, and program product. Background Art

[0002] The starting battery is a vital component in maintaining the normal operation of a vehicle. Its primary function is to provide a high instantaneous current to start the vehicle, driving the starter motor to initiate movement. It also powers low-voltage electrical equipment such as lights, horns, and instrument panels, meeting the vehicle's daily power needs. It also works in conjunction with the power battery to share power supply and, in emergencies, can serve as an emergency power source. However, when a vehicle is idle for an extended period, the starting battery's charge slowly depletes to meet the vehicle's static power consumption, and may even become depleted, preventing the vehicle from starting.

[0003] In order to solve the problem of low starting battery power, people often choose to unplug the negative pole of the starting battery to reduce power loss. However, due to the complex structure of the vehicle, manual operation is inconvenient and dangerous. Summary of the Invention

[0055] The above is only a specific implementation method of the present application, but the protection scope of the present application is not limited to this. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the protection scope of this application. Therefore, the protection scope of this application should be based on the protection scope of the claims. With the development of new energy vehicles, users have higher and higher requirements for the quality of the whole vehicle. Some users do not use the vehicle for a long time (such as long-term business trips). In order to ensure that the whole vehicle does not run out of power, the user needs to start the vehicle and charge it every once in a while, otherwise the whole vehicle cannot start; or the user needs to unplug the negative pole of the starting battery to reduce power loss, but the starting battery of some models is not easy to unplug the negative pole, which brings inconvenience to the user's operation, and not unplugging the negative pole may cause the whole vehicle to run out of power and cannot start normally.

[0056] To address the above technical issues, the present application proposes a battery power preservation method. The method comprises the following steps: receiving a power preservation instruction; executing a power preservation operation in response to the power preservation instruction; and maintaining the vehicle's starting battery at a high charge level. Upon receiving the power preservation instruction, the method executes the power preservation operation to maintain the starting battery at a high charge level, ensuring the vehicle can start normally. It is understood that the battery power preservation method provided in the embodiments of the present application can automatically execute the power preservation operation based on the power preservation instruction, eliminating the need for manual user operation and improving safety and convenience.

[0057] Figure 1 This is a schematic diagram of an application scenario of a battery power conservation method provided in an embodiment of the present application. Figure 1 As shown, the system includes a terminal device 100 and a vehicle 200. The terminal device 100 and the vehicle 200 are in communication connection.

[0058] The terminal device 100 is used to generate a power conservation instruction in response to a user operation and send the power conservation instruction to the vehicle 200.

[0059] For example, the terminal device 100 can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, etc. The embodiments of the present application do not limit the application scenarios. The terminal can sometimes also be referred to as a user, UE, access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent or UE device, etc., and the embodiments of the present application do not limit this.

[0060] For example, after the user sets the power preservation time in the mobile phone application, he clicks the "Send Power Preservation Instruction" button, and the application sends a data packet containing information such as the power preservation time to the vehicle's control module via the wireless network.

[0061] The vehicle 200 is configured to execute a power conservation operation in response to a power conservation instruction, wherein the power conservation instruction is configured to instruct the vehicle 200 to maintain the starting battery 202 at a high power state.

[0062] In some embodiments, as Figure 2 As shown, the vehicle 200 includes a battery management system 201, a starting battery 202 and a power battery 203. The battery management system 201 is connected to the starting battery 202 and the power battery 203 respectively, and the starting battery and the power battery 203 are connected.

[0063] It should be noted that in the entire vehicle system of an electric vehicle, the power battery is the vehicle's core energy storage system, which is used to store and release electrical energy to drive the electric motor, enabling the vehicle to start, accelerate and continue driving.

[0064] The power battery 203 involved in this application is mainly used to charge the starting battery 202 in response to the control instructions of the battery management system 201.

[0065] For example, common starting batteries and power batteries include lead-acid batteries, nickel-metal hydride batteries, lithium-ion batteries, lithium iron phosphate batteries, and the like.

[0066] In some embodiments, the battery management system (BMS) 201 is configured to receive a power conservation instruction and perform a power conservation operation based on the power conservation instruction.

[0067] In some embodiments, the battery management system 201 is configured to generate a control instruction in response to the power conservation instruction, wherein the control instruction is configured to control the starting battery 202 or the power battery 203 to perform a power conservation operation.

[0068] In some embodiments, the power conservation instruction includes a power conservation time, and the battery management system 201 performs a power conservation operation based on the power conservation time.

[0069] In some embodiments, the battery management system 201 is specifically configured to obtain the voltage of the starting battery 202 in response to the power conservation instruction and select different power conservation operations based on the relationship between the voltage and the target voltage. The target voltage represents the minimum voltage of the starting battery 202 required to support the starting of the vehicle 200.

[0070] In some embodiments, when the voltage value of the starting battery 202 is less than or equal to the target voltage value, the power conservation operation includes: the battery management system 201 controls the power battery 203 to charge the starting battery 202 .

[0071] In some embodiments, the battery management system 201 is specifically configured to determine a charging duration of the starting battery 202 based at least on the power preservation duration, and charge the starting battery 202 based on the charging duration of the starting battery 202 .

[0072] In some embodiments, the battery management system 201 is specifically configured to obtain the ambient temperature of the starting battery 202 , and determine the charging time of the starting battery 202 by the power battery 203 based on the power retention time and the ambient temperature of the starting battery 202 .

[0073] In some embodiments, the battery management system 201 is specifically configured to control the power battery 203 to charge the starting battery 202 based on the charging duration of the starting battery 202 .

[0074] In some embodiments, when the voltage value of the starting battery 202 is less than or equal to the target voltage value, or the power battery 203 completes charging the starting battery 202 , the battery management system 201 is specifically configured to control the starting battery 202 to be powered off.

[0075] It should be noted that Figure 1 and Figure 2 This is just an illustrative framework diagram. Figure 1 and Figure 2 The number of devices included in the Figure 2 In addition to the devices shown, other devices may also be included, which is not limited in the embodiments of the present application.

[0076] It should be noted that the application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0077] The following is a detailed introduction to the battery power preservation method provided in the embodiment of the present application.

[0078] Figure 3 A flow chart of a battery power conservation method provided in an embodiment of the present application is applied to Figure 2 The battery management system 201 shown. Figure 3 As shown, the method includes:

[0079] S100: Receive a power conservation instruction.

[0080] Among them, the power preservation instruction is used to instruct the vehicle to perform a power preservation operation to maintain the vehicle's starting battery in a high power state.

[0081] In some embodiments, the power preservation instruction includes a power preservation time period, which is used to maintain the starting battery in a high power state during the power preservation time period.

[0082] In some embodiments, the receiving of the power conservation instruction may be implemented as: receiving the power conservation instruction sent by a user terminal.

[0083] Exemplarily, the user terminal may be an electronic device with wireless transceiver capabilities, such as a computer, a mobile phone, etc.

[0084] Exemplarily, the power preservation duration may be in the form of a preset time range (with a clear start time and end time), and the power preservation instruction is used to maintain the vehicle starting battery in a high power state within the preset time range.

[0085] Exemplarily, the power conservation time may be in the form of a preset time length. After receiving the power conservation instruction, the battery management system executes an operation corresponding to the power conservation instruction and starts a countdown based on the preset time length.

[0086] S200 , in response to the power conservation instruction, executing a power conservation operation.

[0087] Among them, the power preservation operation is used to maintain the vehicle's starting battery in a high power state.

[0088] In some embodiments, the starting battery being in a high power state may mean that the state of charge (SOC) of the starting battery is greater than or equal to a preset SOC threshold; or, the starting battery being in a high power state may mean that the voltage of the starting battery is greater than or equal to a preset voltage threshold.

[0089] In some embodiments, the starting battery being in a high power state indicates that after the power preservation period ends, the power of the starting battery is able to support the starting of the vehicle.

[0090] It is understood that the battery power preservation method provided in this application can, upon receiving a power preservation instruction, perform a power preservation operation to maintain the starting battery at a high charge state, ensuring that the vehicle can start normally. It is understood that the battery power preservation method provided in the embodiments of this application can automatically perform the power preservation operation based on the power preservation instruction, eliminating the need for manual user operation, thereby improving safety and convenience.

[0091] In some embodiments, the above step S200 can be specifically implemented as: in response to the power preservation instruction, when it is detected that the vehicle is in a preset state, performing a power preservation operation.

[0092] The preset state includes at least one of the following: the vehicle is in a non-working state, the vehicle is in an anti-theft locked state, and there are no passengers in the vehicle.

[0093] For example, it can be determined whether the vehicle is in a non-operating state by detecting whether the engine is turned off, whether the headlights are turned off, etc.

[0094] For example, whether the vehicle is in the anti-theft lock state can be determined based on the electronic signal of the vehicle door lock.

[0095] For example, the absence of passengers in the vehicle may be detected through data from a seat pressure sensor and an infrared human body sensing sensor.

[0096] It is understood that the battery power preservation method provided in this application can, upon receiving a power preservation instruction, perform a power preservation operation to maintain the starting battery at a high charge state, ensuring that the vehicle can start normally. It is understood that the battery power preservation method provided in the embodiments of this application can automatically perform the power preservation operation based on the power preservation instruction, eliminating the need for manual user operation, thereby improving safety and convenience.

[0097] As a possible implementation, performing the power conservation operation includes: charging the starting battery when the total voltage of the starting battery is less than the target voltage value. The process of charging the starting battery is described in steps S210-S220 and is not repeated here.

[0098] In some embodiments, the target voltage value represents the minimum voltage value required for the starting battery to drive the starter motor to successfully start the vehicle engine. For example, the target voltage value range for a lead-acid battery is typically 11.8V-12.8V. For some large vehicles, the target voltage value range for the starting battery is typically 22V-26V. The target voltage value can be set based on actual conditions and is not limited in this application.

[0099] In some embodiments, charging the starting battery includes controlling a power battery of the vehicle to charge the starting battery. Exemplarily, a battery management system generates a control instruction and sends the control instruction to the power battery, so that the power battery charges the starting battery according to the control instruction.

[0100] As another possible implementation, executing the power conservation operation includes: controlling the starting battery to cut off power when the total voltage of the starting battery is greater than a target voltage value.

[0101] In some embodiments, controlling the power off of the starting battery includes disconnecting a relay and / or a power switch of the starting battery. Exemplarily, the power switch may be a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), also known as a MOS transistor.

[0102] In some embodiments, as Figure 4 As shown, when the power conservation instruction includes the power conservation duration, the above-mentioned charging of the startup battery can be implemented as the following steps S210-S220:

[0103] S210: Determine a charging time of the starting battery based at least on the power conservation time.

[0104] It should be noted that after the starting battery is powered off, it has a small discharge current because it has its own controller, that is, the power of the starting battery will slowly decrease over time. Therefore, when determining the charging time of the starting battery, it is necessary to consider the impact of the power preservation time on the charging time.

[0105] In some embodiments, the charging time of the startup battery is positively correlated with the power preservation time.

[0106] It should be noted that since there is a chemical reaction inside the battery and the ambient temperature is an important factor affecting the chemical reaction, it is believed that when the power retention time is long, the influence of the ambient temperature needs to be considered when determining the charging time of the starting battery.

[0107] Based on this, Figure 5 As shown, the above S210 can also be implemented as follows:

[0108] S211 : Determine a charging time of the starting battery based on the power conservation time and the ambient temperature.

[0109] In some embodiments, as Figure 6 As shown, the above determination of the charging time of the starting battery based on the power preservation time and the ambient temperature can be specifically implemented as follows:

[0110] S310: When the power conservation time is longer than the preset time, determine whether the ambient temperature is lower than a first preset ambient temperature.

[0111] S320: When the ambient temperature is lower than a first preset ambient temperature, determine the charging duration to be a first charging duration.

[0112] S330: If the ambient temperature is greater than or equal to the first preset ambient temperature, determine whether the ambient temperature is less than a second preset ambient temperature. S340: If the ambient temperature is greater than or equal to the first preset ambient temperature and less than the second preset ambient temperature, determine the charging duration to be a second charging duration.

[0113] S350: When the ambient temperature is greater than or equal to the second preset ambient temperature, determine the charging time to be a third charging time.

[0114] Exemplarily, for a starting iron battery, the third charging time is greater than the second charging time, and the second charging time is greater than the first charging time.

[0115] It should be noted that for different types of starting batteries, the relationship between charging time, power retention time and ambient temperature is different. This application does not make any specific limitation on the charging time.

[0116] For example, through a large number of experiments, the charging time data of the battery under different power-saving times and ambient temperatures are collected. For example, at different ambient temperatures, charging experiments are carried out on the battery after different power-saving times, the charging time is recorded, and the compensation coefficients for different ambient temperatures are determined. Then, based on the experimental data, a formula is established to describe the relationship between the power-saving time, ambient temperature and charging time. For example, the charging time T = a × (power-saving time / preset time) ^ b × (ambient temperature compensation coefficient), where a and b are constants obtained by fitting the experimental data. For example, at different ambient temperatures such as -20°C, 0°C, 20°C, and 40°C, charging experiments are carried out on the battery after different power-saving times such as 1 hour, 5 hours, and 10 hours, and the charging time of each experiment is recorded. Then, a and b are determined by fitting methods such as the least squares method.

[0117] It can be understood that determining the charging time based on the power preservation time and the ambient temperature can eliminate the impact of power loss caused by self-discharge of the starting battery during the power preservation time. At the same time, considering the impact of the ambient temperature on the starting battery charging process and the discharge process during the power preservation period, the charging measurement can be further optimized and the charging time can be accurately grasped.

[0118] In some embodiments, you can also choose to obtain information such as the current battery level and health status of the battery, perform a comprehensive analysis based on various information, and determine a more accurate charging time.

[0119] In some embodiments, the charging stage includes a constant current charging stage and a trickle charging stage. According to the charging characteristics and current working conditions of the battery, charging models for different stages are established to calculate the charging time of each stage.

[0120] It is understandable that by comprehensively considering multiple factors (such as the battery life and ambient temperature) to determine the charging time of the starting battery, the accuracy of calculating the charging time can be improved, so that the starting battery is in a high power state after charging is completed.

[0121] S220: Charge the starting battery based on the charging time of the starting battery.

[0122] In some embodiments, during the battery charging process, if a large fluctuation in the ambient temperature is detected (ie, the ambient temperature fluctuation exceeds a threshold), the charging time is recalculated and the battery charging state is dynamically adjusted.

[0123] In some embodiments, the vehicle charges the starting battery based on the charging time of the starting battery. When the starting battery charging reaches the charging time, the charging is stopped and the starting battery is controlled to be powered off.

[0124] In some embodiments, based on the embodiment of step S100 above, the battery preservation duration can be in the form of a preset time range or a preset time length. When the preset time range ends or the total actual power-off duration of the starting battery reaches the preset time length, the battery preservation operation further includes: controlling the starting battery to be powered on. At this point, the battery preservation method provided by this application ends.

[0125] For example, five minutes before the end of the battery life, the startup battery's voltage, internal resistance, temperature, and other parameters are tested. If the battery voltage falls below a set safety threshold, or if the internal resistance is too high or the temperature is abnormal, an alarm is triggered, powering on is delayed, and a warning message is sent to the user terminal, reminding the user to check the battery status.

[0126] It is understood that the battery preservation method provided in the embodiments of the present application, by receiving an instruction including a preservation duration and automatically executing the preservation operation, eliminates the need for manual user intervention, significantly improving convenience and safety. Furthermore, when executing the preservation operation, the charging duration is determined by comprehensively considering multiple factors, including the starting battery voltage, the vehicle's preset state, the preservation duration, and the ambient temperature. Based on this duration, the starting battery is charged or powered off. This method accurately maintains the starting battery's charge, ensuring that the starting battery is at a high charge after the preservation duration expires, ensuring smooth vehicle startup, and avoiding problems such as startup failures due to insufficient battery charge.

[0127] The following is an introduction to the battery power preservation method provided by this application through a complete embodiment. Figure 7 As shown, the following steps are included:

[0128] S1. Receive power-saving instructions.

[0129] Among them, the power supply instructions include the power supply duration.

[0130] In some embodiments, receiving the power preservation instruction includes receiving the power preservation instruction sent by a user terminal.

[0131] S2. Obtain the voltage of the starting battery and determine the relationship between the voltage of the starting battery and the target voltage value.

[0132] Assume that the starting battery voltage is V1 and the target voltage is V0;

[0133] If V1≤V0, execute S3;

[0134] If V1>V0, execute S6.

[0135] The target voltage value is determined according to actual conditions and is not limited here.

[0136] S3. Determine whether the power conservation time is greater than a preset time.

[0137] Assume that the power conservation time is t0 and the preset time is t;

[0138] If t0≤t, execute step S4;

[0139] If t0>t, execute step S5.

[0140] S4. Determine charging time t1 of the starting battery based on the power conservation time.

[0141] S5. Determine a charging time for the starting battery based on a relationship between the ambient temperature of the starting battery and the first preset ambient temperature and the second preset ambient temperature, the power preservation time, and the ambient temperature of the starting battery.

[0142] The second preset ambient temperature is greater than the first preset ambient temperature.

[0143] For example, assuming that the ambient temperature is T, the first preset ambient temperature is T1, and the second preset ambient temperature is T2, the above step S5 can be implemented as follows:

[0144] If T<T1, the charging time t2 of the starting battery is determined based on the power preservation time and the ambient temperature;

[0145] If T1≤T<T2, the charging time t3 of the starting battery is determined based on the power preservation time and the ambient temperature;

[0146] If T≥T2, the charging time t4 of the starting battery is determined based on the power preservation time and the ambient temperature.

[0147] In some embodiments, t2 < t3 < t4.

[0148] S6. Charging the starting battery based on the charging time of the starting battery.

[0149] In some embodiments, the vehicle power battery is controlled to charge the starting battery.

[0150] After the battery charging is started and the charging time reaches the charging time, step S7 is executed.

[0151] S7. Control the starting battery to cut off power.

[0152] In some embodiments, controlling the power off of the starting battery includes disconnecting a relay and / or a power switch of the starting battery.

[0153] S8. Countdown is performed based on the power conservation time. After the countdown ends, the starting battery is powered on.
