Description

Technical Field

[0001] This application relates to the field of lithium battery technology, and in particular to a lithium battery discharge control method, system, terminal and storage medium. Background Technology

[0002] A lithium battery is a battery that contains lithium (including metallic lithium, lithium alloys, lithium ions, and lithium polymers) in its electrochemical system. It is widely used in various fields due to its advantages such as high specific energy, long cycle life, low self-discharge rate, and no pollution.

[0003] However, due to improper use of lithium batteries, such as over-discharging, the capacity of lithium batteries will decrease or other malfunctions will occur over time, thus affecting the lifespan of lithium batteries and even threatening people's lives and property. Summary of the Invention

[0004] To help improve the discharge control of lithium batteries and reduce the occurrence of over-discharge, this application provides a lithium battery discharge control method, system, terminal, and storage medium.

[0005] Firstly, this application provides a lithium battery discharge control method, which adopts the following technical solution: A lithium battery discharge control method, comprising: Obtain the current charge level of the target lithium battery; Determine whether the current battery level is less than or equal to a preset battery threshold; If the current battery level is less than or equal to the preset battery level threshold, then the current state of the target lithium battery is obtained; Determine whether the current state is a discharge state; If the target lithium battery is in the discharged state, then obtain the power supply plan related to the target lithium battery; Determine whether the power supply plan meets the preset power supply requirements; If the power supply plan does not meet the preset power supply requirements, the discharge state of the target lithium battery will be interrupted.

[0006] By adopting the above technical solution, it is first determined whether the current power level is less than or equal to the preset power level threshold. If it is less than or equal to the threshold, it indicates that the current power level of the target lithium battery is already low. If it continues to discharge, there is a possibility of over-discharge. Therefore, it is necessary to further obtain the current state of the target lithium battery and determine whether the current state is a discharge state. If it is a discharge state, it indicates that the target lithium battery is still discharging. In order to reduce the occurrence of over-discharge, it is necessary to obtain the power supply plan related to the target lithium battery and determine whether the power supply plan meets the preset power supply requirements. If it does not meet the requirements, it indicates that the importance of the power supply plan is low. Under the condition that the current power level is low, it is not necessary to continue discharging. Therefore, the discharge state of the target lithium battery is interrupted. Through multiple assessments, it was ultimately determined that the target lithium battery did not need to continue discharging given its low current charge and low importance to the power supply plan. Strengthening the discharge control of the lithium battery helps reduce the occurrence of over-discharge.

[0007] Optionally, the specific steps for determining whether the power supply plan meets the preset power supply requirements include: Based on the power supply plan, obtain the target power supply terminal for the target lithium battery; Obtain the power supply level of the target power supply terminal; Determine whether the power supply level exceeds a preset first-level threshold; If the power supply level does not exceed the preset first level threshold, then the power supply plan is determined to not meet the preset power supply requirements.

[0008] By adopting the above technical solution, the power supply level of the target power supply terminal is obtained, and it is determined whether the power supply level exceeds the preset first level threshold. If it does not exceed the threshold, it indicates that the power supply level of the target terminal is low. When the target lithium battery is currently low in power, there is no need to continue to supply power. Therefore, it is determined that the power supply plan does not meet the preset power supply requirements. By judging whether the power supply plan meets the preset power supply requirements through the power supply level of the target terminal, it is helpful to determine whether the target lithium battery needs to continue to discharge based on the judgment result, thereby reducing unnecessary discharge and thus helping to reduce the occurrence of over-discharge.

[0009] Optionally, after determining whether the power supply level exceeds a preset first level threshold, the method further includes: If the power supply level exceeds the preset first level threshold, then obtain the current execution task of the target power supply terminal; Obtain the task level of the currently executing task; Determine whether the task level exceeds a preset second-level threshold; If the task level does not exceed the preset second level threshold, then the power supply plan is determined to not meet the preset power supply requirements; If the task level exceeds the preset second level threshold, then the power supply plan is determined to meet the preset power supply requirements.

[0010] By adopting the above technical solution, if the power supply level exceeds the preset first level threshold, it indicates that the power supply level is high. In order to further determine whether the power supply plan meets the preset power supply requirements, it is necessary to obtain the task level of the currently executing task and determine whether the task level exceeds the preset second level threshold. If it does not exceed the threshold, it indicates that even if the power supply level of the target power supply terminal is high, the task level of the currently executing task is low. When the target lithium battery is currently low in power, it is still not necessary to continue to supply power. Therefore, it is determined that the power supply plan does not meet the preset power supply requirements. If the power supply level exceeds the first level threshold, it continues to determine whether the task level exceeds the preset second level threshold. Only when both the power supply level and the task level exceed the preset second level threshold is the power supply plan deemed to meet the preset power supply requirements. By strengthening the discharge control of the lithium battery, it helps to reduce the situation where the target lithium battery still needs to be discharged when its current charge is low, thus preventing over-discharge.

[0011] Optionally, after determining whether the power supply plan meets the preset power supply requirements, the following steps are included: If the power supply plan meets the preset power supply requirements, then the planned power supply duration and the current power supply duration are obtained based on the power supply plan. Based on the planned power supply duration and the current power supply duration, the remaining power supply duration is obtained; Determine whether the remaining power supply duration exceeds a preset duration threshold; If the remaining power supply duration does not exceed the preset duration threshold, the discharge state is maintained based on the remaining power supply duration.

[0012] By adopting the above technical solution, if the power supply plan meets the preset power supply requirements, it indicates that the power supply plan is of high importance. Even when the current power is low, there is still a need to continue discharging. In order to further determine whether to continue discharging and reduce the occurrence of over-discharging of the target lithium battery due to continued discharging, the planned power supply duration and the current power supply duration are obtained according to the power supply plan. Then, the remaining power supply duration is obtained according to the planned power supply duration and the current power supply duration. It is determined whether the remaining power supply duration exceeds the preset duration threshold. If it does not exceed the threshold, it indicates that the remaining power supply duration is short. Even if the power supply is supplied according to the planned power supply duration, it will not cause the target lithium battery to over-discharge. Therefore, the discharge state is maintained. Implementing power supply according to the power supply plan while ensuring that the target lithium battery is not over-discharged helps to reduce the occurrence of lithium battery over-discharge and also helps to reduce the impact on users' production and life due to the interruption of discharge.

[0013] Optionally, the specific steps for determining whether the remaining power supply duration exceeds a preset duration threshold include: The initial charge level of the target lithium battery is obtained when the power supply plan begins. Based on the initial battery level and the current battery level, obtain the battery level difference; Based on the power difference and the current power supply duration, a first power consumption rate is obtained; Based on the first power consumption rate and the remaining power supply duration, the first estimated power consumption value is obtained; Determine whether the first estimated power consumption value exceeds the preset first power consumption threshold; If the first estimated power consumption value does not exceed the preset first power consumption threshold, then it is determined that the remaining power supply duration does not exceed the budget duration threshold. If the first estimated power consumption value exceeds the preset first power consumption threshold, then it is determined that the remaining power supply duration exceeds the budget duration threshold.

[0014] By adopting the above technical solution, the initial power level is first obtained, the power difference between the initial power level and the current power level is obtained, the first power consumption rate is obtained based on the power difference and the current power supply duration, and the first power consumption value is obtained based on the first power consumption rate and the remaining power supply duration. It is then determined whether the first power consumption value exceeds the preset first power consumption threshold. If it does not exceed the threshold, it indicates that the first power consumption value corresponding to the remaining power supply duration is low. Even if the discharge continues according to the remaining power supply duration, it will not cause the target lithium battery to over-discharge. Therefore, it is determined that the remaining power supply duration does not exceed the budget duration threshold. If it exceeds the limit, it indicates that the expected first power consumption value corresponding to the remaining power supply time is high. If the discharge continues according to the remaining power supply time, it will cause the target lithium battery to be over-discharged. Therefore, it is determined that the remaining power supply time exceeds the budgeted time threshold. The first power consumption rate is used to calculate the first power consumption value. Finally, the remaining power supply time is determined based on whether the first power consumption value exceeds the preset first power consumption threshold. The determination result determines whether the target lithium battery should continue to discharge. This helps to reduce the occurrence of over-discharge of lithium batteries due to continuous discharge, or helps to reduce the impact on users' production and life due to direct interruption of discharge.

[0015] Optionally, after determining whether the remaining power supply duration exceeds a preset duration threshold, the method further includes: If the remaining power supply duration exceeds the preset duration threshold, then obtain the completion rate of the currently executed task and the task power supply duration; Based on the completion rate and the task power supply duration, a second power consumption rate is obtained; Based on the completion rate, the remaining completion rate is obtained; Based on the second power consumption rate and the degree of completion, obtain the second estimated power consumption value; Determine whether the estimated power consumption value exceeds the preset second power consumption threshold; If the second estimated power consumption value does not exceed the preset second power consumption threshold, then the discharge state is maintained based on the degree of completion. If the second estimated power consumption value exceeds the preset second power consumption threshold, the discharge state of the target lithium battery will be interrupted.

[0016] By adopting the above technical solution, if the remaining power supply time exceeds the preset time threshold, it indicates that the remaining power supply time is relatively long. If the target lithium battery continues to discharge according to the remaining power supply time, it may lead to over-discharge of the target lithium battery. In order to reduce the occurrence of over-discharge of the target lithium battery, it is necessary to obtain the completion rate of the current task and the task power supply time. Based on the completion rate and the task power supply time, the second power consumption rate and the unfinished status are obtained. Based on the second power consumption rate and the unfinished status, the second power consumption value is obtained, and it is determined whether the second power consumption value exceeds the preset second power consumption threshold. If it does not exceed the threshold, it indicates that the power consumption required for the unfinished status of the current task is low. The target lithium battery will not over-discharge even if it continues to discharge until the current task is completed. Therefore, it can maintain the discharge state until the current task is completed. If the power consumption exceeds the limit, it indicates that the power consumption required for the completion of the current task is high. If the target lithium battery continues to discharge until the current task is completed, it will cause the target lithium battery to be over-discharged. Therefore, it cannot maintain the discharge state until the current task is completed and the discharge state of the target lithium battery needs to be interrupted. Based on the estimated power consumption of the current task, determine whether to maintain the target lithium battery's discharge state. If the power allows, execute the appropriate steps according to the actual situation. This not only helps reduce the occurrence of excessive discharge of the lithium battery due to continuous discharge, but also helps reduce the occurrence of the need to re-execute the user's current task after the discharge state is interrupted due to direct interruption of the discharge state.

[0017] Optionally, the specific steps for interrupting the discharge state of the target lithium battery if the power supply plan does not meet the preset power supply requirements include: If the power supply plan does not meet the preset power supply requirements, then determine whether the power supply plan is a preset special power supply plan; If the power supply plan is not the preset special power supply plan, then the discharge state of the target lithium battery will be directly interrupted; If the power supply plan is the preset special power supply plan, then the discharge state of the target lithium battery is interrupted based on the preset parameter threshold.

[0018] By adopting the above technical solution, it is determined whether the power supply plan is a preset special power supply plan. If not, it indicates that the power supply plan related to the target lithium battery is a normal plan. Therefore, when the power supply plan does not meet the preset power supply requirements, the discharge state of the target lithium battery can be directly interrupted. If yes, it indicates that the power supply plan related to the target lithium battery is a preset special power supply plan. Therefore, when the power supply plan does not meet the preset power supply requirements, it is necessary to interrupt the discharge state of the target lithium battery according to the preset parameter threshold. Adopting different solutions according to different situations helps to reduce the occurrence of failure of the target power supply terminal connected to the target lithium battery due to direct interruption of the discharge state.

[0019] Secondly, this application also discloses a lithium battery discharge control system, which adopts the following technical solution: A lithium battery discharge control system, comprising: The first acquisition module is used to acquire the current power level of the target lithium battery; The first judgment module is used to determine whether the current battery level is less than or equal to a preset battery threshold. If the current power level is less than or equal to the preset power level threshold, the second acquisition module is used to acquire the current state of the target lithium battery. The second judgment module is used to determine whether the current state is a discharge state; The third acquisition module, if the target lithium battery is in the discharge state, is used to acquire the power supply plan for the target lithium battery; The third judgment module is used to determine whether the power supply plan meets the preset power supply requirements; If the power supply plan does not meet the preset power supply requirements, the first execution module is used to interrupt the discharge state of the target lithium battery.

[0020] By adopting the above technical solution, it is first determined whether the current power level is less than or equal to the preset power level threshold. If it is less than or equal to the threshold, it indicates that the current power level of the target lithium battery is already low. If it continues to discharge, there is a possibility of over-discharge. Therefore, it is necessary to further obtain the current state of the target lithium battery and determine whether the current state is a discharge state. If it is a discharge state, it indicates that the target lithium battery is still discharging. In order to reduce the occurrence of over-discharge, it is necessary to obtain the power supply plan related to the target lithium battery and determine whether the power supply plan meets the preset power supply requirements. If it does not meet the requirements, it indicates that the importance of the power supply plan is low. Under the condition that the current power level is low, it is not necessary to continue discharging. Therefore, the discharge state of the target lithium battery is interrupted. Through multiple assessments, it was ultimately determined that the target lithium battery did not need to continue discharging given its low current charge and low importance to the power supply plan. Strengthening the discharge control of the lithium battery helps reduce the occurrence of over-discharge.

[0021] Thirdly, the computer device provided in this application adopts the following technical solution: A smart terminal includes a memory and a processor, wherein the memory stores a computer program that can run on the processor, and when the processor loads the computer program, it executes the method of the first aspect.

[0022] Fourthly, the computer-readable storage medium provided in this application adopts the following technical solution: A computer-readable storage medium storing a computer program that, when loaded by a processor, executes the method of the first aspect.

[0023] In summary, this application includes the following beneficial technical effects: Through multiple assessments, it was ultimately determined that the target lithium battery did not need to continue discharging given its low current charge and low importance to the power supply plan. Strengthening the discharge control of the lithium battery helps reduce the occurrence of over-discharge. Attached Figure Description

[0026] In the first aspect, this application discloses a lithium battery discharge control method.

[0027] Reference Figure 1 A lithium battery discharge control method includes steps S101 to S107: Step S101: Obtain the current charge level of the target lithium battery.

[0028] Specifically, in this embodiment, the target lithium battery is a lithium battery that requires discharge control, and the current charge is the current remaining charge of the target lithium battery; in this embodiment, the current charge of the target lithium battery can be measured and monitored using a coulomb counter.

[0029] Step S102: Determine whether the current battery level is less than or equal to the preset battery level threshold.

[0030] Specifically, in this embodiment, the preset power threshold is a pre-set criterion for determining whether the current power of the target lithium battery is within a safe range. In this embodiment, the power of the target lithium battery can be divided into a safe range, a risk range, and a dangerous range. For example, the safe range corresponds to the power range of the target lithium battery as (30%, 100%), the risk range corresponds to the power range of the target lithium battery as (20%, 30%), and the dangerous range corresponds to the power range of the target lithium battery as [0%, 20%). In this embodiment, the preset power threshold is 30% of the rated power of the target lithium battery, and the rated power is pre-stored in the lithium battery discharge control system.

[0031] Step S103: If the current power level is less than or equal to the preset power level threshold, then obtain the current state of the target lithium battery.

[0032] Specifically, in this embodiment, the current state includes a discharging state, a charging state, and a stationary state. The discharging state indicates that the target lithium battery is discharging, the charging state indicates that the target lithium battery is charging, and the stationary state indicates that the target lithium battery is neither discharging nor charging.

[0033] If the current battery level is greater than the preset battery level threshold, the current operation can be terminated.

[0034] Step S104: Determine whether the current state is a discharge state.

[0035] Specifically, in this embodiment, it can be determined whether the target lithium battery is in a discharged state by checking whether it has electrical energy output.

[0036] Step S105: If the target lithium battery is in a discharged state, obtain the power supply plan related to the target lithium battery.

[0037] Specifically, in this embodiment, the power supply plan is a plan to supply power to the load through the target lithium battery. In this embodiment, the power supply plan includes the power supply duration, the start and end times of the power supply, and information about the load supplied by the target lithium battery.

[0038] If the target lithium battery is charging, the current operation can be terminated; if the target lithium battery is stationary, a low battery reminder can be generated to remind the user to charge the target lithium battery in time.

[0039] Step S106: Determine whether the power supply plan meets the preset power supply requirements.

[0040] Specifically, in this embodiment, there are preset power supply requirements and pre-set criteria for determining whether the target lithium battery still needs to continue discharging when its current charge level is not within a safe range.

[0041] Step S107: If the power supply plan does not meet the preset power supply requirements, the discharge state of the target lithium battery is interrupted.

[0042] Specifically, in this embodiment, if the power supply plan does not meet the preset power supply requirements, the discharge state will be directly interrupted when the current power level of the target lithium battery is not within the safe range; in this embodiment, a low power reminder can also be generated to remind the user to charge the target lithium battery in time.

[0043] The lithium battery discharge control method provided in this embodiment first determines whether the current charge level is less than or equal to a preset charge threshold. If it is less than or equal to the current charge level, it indicates that the current charge level of the target lithium battery is already low. If the discharge continues, there is a possibility of over-discharge. Therefore, it is necessary to further obtain the current state of the target lithium battery and determine whether the current state is a discharge state. If it is a discharge state, it indicates that the target lithium battery is still discharging. In order to reduce the occurrence of over-discharge, it is necessary to obtain the power supply plan related to the target lithium battery and determine whether the power supply plan meets the preset power supply requirements. If it does not meet the requirements, it indicates that the importance of the power supply plan is low. Under the condition that the current charge level is low, it is not necessary to continue discharging. Therefore, the discharge state of the target lithium battery is interrupted.

[0044] Through multiple assessments, it was ultimately determined that the target lithium battery did not need to continue discharging given its low current charge and low importance to the power supply plan. Strengthening the discharge control of the lithium battery helps reduce the occurrence of over-discharge.

[0045] Reference Figure 2 In one embodiment of this example, the specific steps of step S106, which determines whether the power supply plan meets the preset power supply requirements, further include steps S201 to S204: Step S201: Based on the power supply plan, obtain the target power supply terminal for the target lithium battery.

[0046] Specifically, in this embodiment, the target power supply terminal, i.e. the terminal load of the target lithium battery, such as a computer, television, and light, can be obtained from the power supply plan.

[0047] Step S202: Obtain the power supply level of the target power supply terminal.

[0048] Specifically, in this embodiment, the power supply level refers to the importance level of the target power supply terminal. The power supply level of each target power supply terminal is pre-stored in the lithium battery discharge control system. The power supply level can be set according to the importance of the target power supply terminal or according to the user's usage habits. In this embodiment, the power supply level can be level one, level two, and level three, with the importance order being level three > level two > level one.

[0049] Step S203: Determine whether the power supply level exceeds the preset first level threshold.

[0050] Specifically, in this embodiment, the preset first-level threshold is the judgment standard for determining whether the power supply plan meets the preset power supply requirements based on the power supply level. In this embodiment, the preset first-level threshold can be level one.

[0051] Step S204: If the power supply level does not exceed the preset first level threshold, it is determined that the power supply plan does not meet the preset power supply requirements.

[0052] Specifically, in this embodiment, if the power supply level does not exceed the preset first level threshold, the power supply level of the power supply plan is level one, which is of low importance and therefore does not meet the preset power supply requirements.

[0053] The lithium battery discharge control method provided in this embodiment obtains the power supply level of the target power supply terminal and determines whether the power supply level exceeds a preset first level threshold. If it does not exceed the threshold, it indicates that the power supply level of the target terminal is low. Since the target lithium battery is currently low in power, there is no need to continue supplying power. Therefore, it is determined that the power supply plan does not meet the preset power supply requirements. By determining whether the power supply plan meets the preset power supply requirements through the power supply level of the target terminal, it is helpful to determine whether the target lithium battery needs to continue discharging based on the judgment result, thereby reducing unnecessary discharge and helping to reduce the occurrence of over-discharge.

[0054] Reference Figure 3 In one embodiment of this example, after determining whether the power supply level exceeds a preset first level threshold in step S203, steps S301 to S305 are further included: Step S301: If the power supply level exceeds the preset first level threshold, obtain the current execution task of the target power supply terminal.

[0055] Specifically, in this embodiment, the currently executing task is the task that the target power supply terminal is currently executing. For example, if the target power supply terminal is a computer and the computer is downloading a file, then the currently executing task is downloading a file. If the target power supply terminal is a light and the light is illuminating, then the currently executing task is illuminating.

[0056] Step S302: Obtain the task level of the currently executing task.

[0057] Specifically, in this embodiment, the task level refers to the importance level of the currently executed task. In the lithium battery discharge control system, different types of currently executed tasks are preset and stored. The task level can be set according to the importance of the currently executed task or according to the user's wishes. In this embodiment, the task level can be level A, level B, and level C, with the importance order being level C > level B > level A.

[0058] Step S303: Determine whether the task level exceeds the preset second-level threshold.

[0059] Specifically, in this embodiment, the preset second-level threshold is the second judgment criterion for determining whether the power supply plan meets the preset power supply requirements based on the task level. In this embodiment, the preset second-level threshold can be level A.

[0060] Step S304: If the task level does not exceed the preset second level threshold, it is determined that the power supply plan does not meet the preset power supply requirements.

[0061] Specifically, in this embodiment, if the task level does not exceed the preset second level threshold, the task level of the currently executing task is level A, which is of low importance and therefore does not meet the preset power supply requirements.

[0062] Step S305: If the task level exceeds the preset second level threshold, the power supply plan is determined to meet the preset power supply requirements.

[0063] Specifically, in this embodiment, if the task level exceeds the preset second level threshold, the task level of the currently executing task is level B or level C, which is of high importance and therefore meets the preset power supply requirements.

[0064] The lithium battery discharge control method provided in this embodiment indicates that the power supply level is high if the power supply level exceeds the preset first level threshold. In order to further determine whether the power supply plan meets the preset power supply requirements, it is necessary to obtain the task level of the currently executed task and determine whether the task level exceeds the preset second level threshold. If it does not exceed the threshold, it indicates that even if the power supply level of the target power supply terminal is high, the task level of the currently executed task is low. When the current power of the target lithium battery is low, it is still not necessary to continue to supply power. Therefore, it is determined that the power supply plan does not meet the preset power supply requirements.

[0065] If the power supply level exceeds the first level threshold, it continues to determine whether the task level exceeds the preset second level threshold. Only when both the power supply level and the task level exceed the preset second level threshold is the power supply plan deemed to meet the preset power supply requirements. By strengthening the discharge control of the lithium battery, it helps to reduce the situation where the target lithium battery still needs to be discharged when its current charge is low, thus preventing over-discharge.

[0066] Reference Figure 4 In one embodiment of this example, after determining whether the power supply plan meets the preset power supply requirements in step S106, steps S401 to S404 are further included: Step S401: If the power supply plan meets the preset power supply requirements, then obtain the planned power supply duration and the current power supply duration based on the power supply plan.

[0067] Specifically, in this embodiment, the planned power supply duration is the power supply duration set in the power supply plan, which can be directly obtained from the power supply plan; the current power supply duration is the duration from the time node corresponding to the start of power supply to the current time node. The current power supply duration can be obtained by subtracting the time node corresponding to the start of power supply from the current time node. When the target lithium battery starts to supply power, the lithium battery discharge control system will record the power supply information, including the time node, voltage and current magnitude, etc.

[0068] Step S402: Based on the planned power supply duration and the current power supply duration, obtain the remaining power supply duration.

[0069] Specifically, in this embodiment, the remaining power supply duration is the difference between the planned power supply duration and the current power supply duration. For example, if the planned power supply duration is 60 minutes and the current power supply duration is 50 minutes, then the remaining power supply duration is 60-50=10 minutes.

[0070] Step S403: Determine whether the remaining power supply duration exceeds the preset duration threshold.

[0071] Specifically, in this embodiment, the preset duration threshold is a pre-set criterion used to determine whether there is over-discharge after the target lithium battery continues to discharge for the remaining power supply time when the current voltage is not within the safe range. In this embodiment, the preset duration threshold can be set to 10 minutes, or it can be set according to the time required to consume 5% of the power.

[0072] Step S404: If the remaining power supply duration does not exceed the preset duration threshold, then maintain the discharge state based on the remaining power supply duration.

[0073] The lithium battery discharge control method provided in this embodiment indicates that the power supply plan is of high importance if it meets the preset power supply requirements. Even if the current power is low, there is still a need to continue discharging. In order to further determine whether to continue discharging and reduce the occurrence of over-discharging of the target lithium battery due to continued discharging, the planned power supply duration and the current power supply duration are obtained according to the power supply plan. Then, the remaining power supply duration is obtained according to the planned power supply duration and the current power supply duration. It is determined whether the remaining power supply duration exceeds the preset duration threshold. If it does not exceed the threshold, it indicates that the remaining power supply duration is short. Even if the power supply is supplied according to the planned power supply duration, it will not cause the target lithium battery to over-discharge. Therefore, the discharge state is maintained.

[0074] Implementing power supply according to the power supply plan while ensuring that the target lithium battery is not over-discharged helps to reduce the occurrence of lithium battery over-discharge and also helps to reduce the impact on users' production and life due to the interruption of discharge.

[0075] Reference Figure 5In one embodiment of this example, the specific steps of step S403, which determines whether the remaining power supply duration exceeds a preset duration threshold, include steps S501 to S507: Step S501: Obtain the target lithium battery's charge level at the start of the power supply plan as the initial charge level.

[0076] Specifically, in this embodiment, the initial charge is the charge level of the target lithium battery when it begins to supply power to the target power supply terminal according to the power supply plan. The initial charge level can be obtained from the power supply information recorded by the lithium battery discharge control system.

[0077] Step S502: Obtain the power difference based on the initial power level and the current power level.

[0078] Specifically, in this embodiment, the power difference is the difference between the initial power and the current power. For example, if the initial power is 80% and the current power is 30%, then the power difference is 50%.

[0079] Step S503: Based on the power difference and the current power supply duration, obtain the first power consumption rate.

[0080] Specifically, in this embodiment, the first power consumption rate is the value obtained by dividing the power difference by the current power supply duration. For example, if the rated power of the target lithium battery is 'a', the power difference is 50%, and the current power supply duration is 60 minutes, then the first power consumption rate = 50% / 60 = 0.3%, which means that 0.3% of the power is consumed per minute.

[0081] Step S504: Based on the first power consumption rate and the remaining power supply duration, obtain the first estimated power consumption value.

[0082] Specifically, in this embodiment, the first power consumption value is the power required for the remaining power supply time calculated based on the first power consumption rate. For example, if the remaining power supply time is 10 minutes and the first power consumption rate is 0.3%, then the first power consumption value is 10 * 0.3% = 3%.

[0083] Step S505: Determine whether the first estimated power consumption value exceeds the preset first power consumption threshold.

[0084] Specifically, in this embodiment, the preset first power consumption threshold is the maximum discharge amount allowed for the remaining power supply time of the target lithium battery when the current power level is not within a safe range.

[0085] Step S506: If the first estimated power consumption value does not exceed the preset first power consumption threshold, then it is determined that the remaining power supply duration does not exceed the budget duration threshold.

[0086] Step S507: If the first power consumption value exceeds the preset first power consumption threshold, then it is determined that the remaining power supply time exceeds the budgeted time threshold.

[0087] The lithium battery discharge control method provided in this embodiment first obtains the initial power level, then obtains the power difference between the initial power level and the current power level, then obtains the first power consumption rate based on the power difference and the current power supply duration, and obtains the first power consumption value based on the first power consumption rate and the remaining power supply duration. It then determines whether the first power consumption value exceeds a preset first power consumption threshold. If it does not exceed the threshold, it indicates that the first power consumption value corresponding to the remaining power supply duration is low, and even if the discharge continues according to the remaining power supply duration, it will not cause the target lithium battery to over-discharge. Therefore, it is determined that the remaining power supply duration does not exceed the budget duration threshold.

[0088] If it exceeds the limit, it indicates that the expected first power consumption value corresponding to the remaining power supply time is high. If the discharge continues according to the remaining power supply time, it will cause the target lithium battery to be over-discharged. Therefore, it is determined that the remaining power supply time exceeds the budgeted time threshold.

[0089] The first power consumption rate is used to calculate the first power consumption value. Finally, the remaining power supply time is determined based on whether the first power consumption value exceeds the preset first power consumption threshold. The determination result determines whether the target lithium battery should continue to discharge. This helps to reduce the occurrence of over-discharge of lithium batteries due to continuous discharge, or helps to reduce the impact on users' production and life due to direct interruption of discharge.

[0090] Reference Figure 6 In one embodiment of this example, after determining whether the remaining power supply duration exceeds a preset duration threshold in step S403, steps S601 to S607 are further included: Step S601: If the remaining power supply duration exceeds the preset duration threshold, obtain the completion rate of the currently executed task and the task power supply duration.

[0091] Specifically, in this embodiment, the completion rate refers to the degree of completion of the currently executed task; the task power supply duration refers to the duration from the time node corresponding to the start of the currently executed task to the current time node.

[0092] Step S602: Based on the completion rate and the task power supply duration, obtain the second power consumption rate.

[0093] Specifically, in this embodiment, the second power consumption rate is the value of the completion rate divided by the task power supply duration. For example, if the completion rate is 90% and the task power supply duration is 60 minutes, then the second power consumption rate is 90% / 60=1.5%, meaning that 1.5% of the power needs to be consumed for every 1% completion rate.

[0094] Step S603: Based on the completion rate, obtain the remaining completion rate.

[0095] Specifically, in this embodiment, the degree of completion to be completed is the value obtained by subtracting the degree of completion from 1. For example, if the degree of completion is 90%, then the degree of completion to be completed = 1 - 90% = 10%.

[0096] Step S604: Based on the second power consumption rate and the degree of completion, obtain the second estimated power consumption value.

[0097] Specifically, in this embodiment, the second power consumption value is the power required to complete the current task under the previous power supply state, calculated based on the second power consumption rate. For example, if the completion rate is 10% and the second power consumption rate is 1.5%, then the second power consumption value is 10 * 1.5% = 15%.

[0098] Step S605: Determine whether the estimated second power consumption value exceeds the preset second power consumption threshold.

[0099] Specifically, in this embodiment, the preset second power consumption threshold is a pre-set maximum discharge amount allowed for the current task to be completed by the target lithium battery when the current power is not within a safe range.

[0100] Step S606: If the estimated second power consumption value does not exceed the preset second power consumption threshold, then maintain the discharge state based on the degree of completion.

[0101] Step S607: If the estimated second power consumption value exceeds the preset second power consumption threshold, the discharge state of the target lithium battery is interrupted.

[0102] The lithium battery discharge control method provided in this embodiment indicates that if the remaining power supply time exceeds a preset time threshold, it means that the remaining power supply time is relatively long. If the target lithium battery continues to discharge according to the remaining power supply time, it may lead to over-discharge of the target lithium battery. In order to reduce the occurrence of over-discharge of the target lithium battery, it is necessary to obtain the completion rate of the currently executed task and the task power supply time. Based on the completion rate and the task power supply time, a second power consumption rate and a pending completion rate are obtained. Then, based on the second power consumption rate and the pending completion rate, a second power consumption value is obtained, and it is determined whether the second power consumption value exceeds the preset second power consumption threshold. If it does not exceed the threshold, it means that the power consumption required for the pending completion rate of the currently executed task is low. The target lithium battery will not over-discharge even if it continues to discharge until the currently executed task is completed. Therefore, it can maintain the discharge state until the currently executed task is completed.

[0103] If the power consumption exceeds the limit, it indicates that the power consumption required for the completion of the current task is high. If the target lithium battery continues to discharge until the current task is completed, it will lead to over-discharge of the target lithium battery. Therefore, it cannot maintain the discharge state until the current task is completed and the discharge state of the target lithium battery needs to be interrupted.

[0104] Based on the estimated power consumption of the current task, determine whether to maintain the target lithium battery's discharge state. If the power allows, execute the appropriate steps according to the actual situation. This not only helps reduce the occurrence of excessive discharge of the lithium battery due to continuous discharge, but also helps reduce the occurrence of the need to re-execute the user's current task after the discharge state is interrupted due to direct interruption of the discharge state.

[0105] Reference Figure 7 In one embodiment of this example, if the power supply plan does not meet the preset power supply requirements, the specific steps for interrupting the discharge state of the target lithium battery in step S107 include steps S701 to S703: Step S701: If the power supply plan does not meet the preset power supply requirements, determine whether the power supply plan is a preset special power supply plan.

[0106] Specifically, in this embodiment, the preset special power supply plan is a pre-set special power supply plan, such as a power supply plan to supply power to a designated target power supply terminal.

[0107] Step S702: If the power supply plan is not a preset special power supply plan, the discharge state of the target lithium battery is directly interrupted.

[0108] Step S703: If the power supply plan is a preset special power supply plan, then the discharge state of the target lithium battery is interrupted based on the preset parameter threshold.

[0109] Specifically, in this embodiment, the preset parameter threshold includes a preset time threshold and a preset power threshold. If the preset parameter threshold is a preset time threshold, it can be set to 1 minute. That is, when the power supply plan does not meet the preset power supply requirements, once the current power of the target lithium battery is less than or equal to the preset power threshold, the discharge state of the target lithium battery will be interrupted after 1 minute.

[0110] If the preset parameter threshold is the preset power threshold, it can be set to 5%. That is, when the power supply plan does not meet the preset power supply requirements, once the current power of the target lithium battery is less than or equal to the preset power threshold, the discharge state of the target lithium battery will be interrupted after continuing to discharge 5%.

[0111] It is worth noting that in this embodiment, in any case where the discharge state of the target lithium battery is interrupted, it can be determined whether the power supply plan is a preset special power supply plan, and then step S702 or step S703 is executed according to the determination result.

[0112] The lithium battery discharge control method provided in this embodiment determines whether the power supply plan is a preset special power supply plan. If not, it indicates that the power supply plan related to the target lithium battery is a normal plan. Therefore, when the power supply plan does not meet the preset power supply requirements, the discharge state of the target lithium battery can be directly interrupted. If yes, it indicates that the power supply plan related to the target lithium battery is a preset special power supply plan. Therefore, when the power supply plan does not meet the preset power supply requirements, it is necessary to interrupt the discharge state of the target lithium battery according to the preset parameter threshold. By adopting different schemes according to different situations, it helps to reduce the occurrence of failure of the target power supply terminal connected to the target lithium battery due to direct interruption of the discharge state.

The third judgment module 6 is used to determine whether the power supply plan meets the preset power supply requirements; If the power supply plan does not meet the preset power supply requirements, the first execution module 7 is used to interrupt the discharge state of the target lithium battery.
