Description

Technical Field

[0001] This invention relates to the field of energy storage battery management technology, specifically to a method, device, electronic equipment, and storage medium for early warning of the depth of discharge of energy storage batteries. Background Technology

[0002] Most existing energy storage battery maintenance solutions are as follows:

[0003] 1. Temperature-based battery protection: This is a standard function of BMS (Battery Management System). When the battery temperature is below 0°C, the BMS will directly prohibit charging (because low-temperature charging will cause lithium plating, damaging the battery), but it usually will not prohibit discharging.

[0004] 2. Simple calendar-based reminders: Some systems may have fixed "winter mode" reminders, but these are usually static (e.g., a uniform reminder on November 1st every year), lacking dynamic judgment based on geographical location and latitude, resulting in poor accuracy for users in different climate zones.

[0005] 3. Manual User Setup: The most common solution currently relies on user manuals and user self-discipline. Manuals often recommend adjusting DOD (Depth of Discharge) before winter, but many users ignore or forget this, leading to problems.

[0006] In summary, the existing technology has the following main drawbacks: 1. Passive Protection Lag: Current mainstream battery management systems only passively disable charging when the battery temperature drops below 0°C to prevent lithium deposition and damage. However, this mechanism cannot prevent the battery from being in a dangerous state of high depth of discharge (DOD) before the low temperature arrives. Once the battery voltage becomes too low due to continuous discharge at low temperatures, even if the temperature rises, the BMS will lock up due to undervoltage and fail to start, causing the battery to "freeze." Manual external intervention is required to wake it up, leading to system failure.

[0007] 2. High user dependence: The solutions largely rely on prior notification in the user manual, requiring users to adjust settings voluntarily during winter. In actual use, users are very likely to forget or ignore this operation, rendering the preventative measures ineffective.

[0008] 3. Lack of accuracy in early warnings: Some systems send reminders on fixed dates (such as November 1st each year), which cannot adapt to the huge differences in latitudes and climate zones around the world. This can cause annoyance to users in low latitudes and may provide insufficient warnings to users in high latitudes. Summary of the Invention

[0009] This invention provides a method, device, electronic device, and storage medium for early warning of the depth of discharge of energy storage batteries, in order to solve the problems of over-discharge damage to energy storage batteries caused by the existing winter protection schemes for energy storage batteries, such as delayed early warning, poor regional adaptability, and low user compliance.

[0010] In a first aspect, the present invention provides a method for early warning of the discharge depth of an energy storage battery, the method comprising: Obtain the current date and the geographical location information of the energy storage power station; the geographical location information should include at least latitude information; Based on the comparison results between latitude information and preset latitude threshold, and the comparison results between the current date and preset season start time, it is determined whether the warning triggering conditions are met. If the warning triggering conditions are met, a warning about the depth of discharge of the energy storage battery in the energy storage power station will be triggered, and a graded warning message will be sent to the user.

[0011] This invention provides a method for early warning of battery discharge depth. By integrating real-time date and power station latitude information and intelligently comparing it with preset spatiotemporal thresholds, it achieves a shift from passive monitoring to proactive prediction. This method can automatically and accurately trigger warnings before the arrival of the cold season and guide users to adjust battery settings in advance through tiered information push notifications. This process effectively prevents performance degradation or permanent damage to batteries due to over-discharge at low temperatures, thus significantly improving the reliability of energy storage power stations in winter. Simultaneously, it reduces maintenance costs and user risks caused by battery failures, achieving a balance between safety and user experience. It solves the problems of delayed warnings, poor regional adaptability, and low user compliance rates leading to over-discharge damage in existing winter protection schemes for energy storage batteries.

[0012] In one optional implementation, based on a comparison between latitude information and a preset latitude threshold, and a comparison between the current date and a preset season start time, it is determined whether the warning triggering conditions are met, including: If the latitude information is greater than or equal to the preset latitude threshold, and the current date reaches or exceeds the preset season start time, then the warning trigger condition is determined to be met.

[0013] This invention provides a method for early warning of deep discharge in energy storage batteries. By combining a static geographical latitude threshold with a dynamic seasonal start time, it achieves spatiotemporal coupled intelligent decision-making. This surpasses simple temperature responses or fixed calendar reminders, predicting and triggering warnings based on geographical location characteristics before the low temperatures of winter actually affect battery performance. This mechanism ensures both the forward-looking and proactive nature of the warnings, while latitude filtering ensures the regional relevance and accuracy of the warnings, avoiding interference with users in areas that do not require special winter protection. Therefore, it improves battery protection reliability while also optimizing the user experience.

[0014] In one optional implementation, the geographic location information further includes altitude information; determining whether the warning triggering conditions are met also includes: If the latitude information is greater than or equal to the preset latitude threshold, and the current date reaches or exceeds the preset season start time, the preset season start time is corrected based on the preset correction rules and altitude information. If the current date reaches or exceeds the revised start time of the season, the warning trigger condition is determined to be met.

[0015] This invention provides a method for early warning of the discharge depth of energy storage batteries. By combining geographical latitude judgment with altitude to dynamically compensate for the start time of the season, it effectively overcomes the shortcomings of the simple latitude model in terms of insufficient early warning accuracy in regions with different altitudes at the same latitude (such as plateaus and plains). This makes the early warning trigger time more in line with the actual local climate conditions, significantly improving the timeliness and accuracy of early warning in high-altitude cold regions, and solving the problem of battery over-discharge damage in high-altitude cold regions.

[0016] In one optional implementation, the preset season start time is corrected based on preset correction rules and altitude information, including: The time advance is calculated based on the difference between the altitude information and the preset altitude threshold, as well as the preset altitude-time advance correspondence. The corrected warning trigger time is obtained by advancing the preset season start time by an additional amount of time.

[0017] This invention provides a method for early warning of the discharge depth of energy storage batteries. By establishing a quantitative correspondence between altitude difference and time advance, it achieves dynamic and refined adjustment of the warning trigger time. This allows the warning trigger time to be advanced proportionally with increasing altitude, thus more accurately matching the climatic characteristics of earlier winters in high-altitude areas, effectively improving the timeliness and regional adaptability of the warnings. This parameterized rule provides the system with a clear and adjustable compensation logic, enhancing the practicality and reliability of the solution.

[0018] In one optional implementation, the preset season start time is corrected based on preset correction rules and altitude information, and further includes: Based on latitude and altitude information, query the preset latitude-altitude-warning trigger time mapping table to directly obtain the corresponding corrected warning trigger time.

[0019] This invention provides a method for early warning of the discharge depth of energy storage batteries. By using a pre-generated "latitude-altitude-early warning trigger time" mapping relationship, the precise early warning trigger time can be directly obtained. This method is simple to implement, responds quickly, and the mapping table can be generated based on long-term historical climate data, ensuring that the early warning trigger time highly matches the actual local climate patterns. This avoids errors or system load that may be introduced by dynamic calculations, and improves the determinism and execution efficiency of the solution.

[0020] In one optional implementation, sending tiered warning information to the user includes: In response to the discharge depth warning of the energy storage battery, a first warning message is sent to the corresponding user through at least one preset communication channel. The first warning message includes suggestions and operation instructions for adjusting the battery discharge depth to a preset safety value. After sending the first warning message, status monitoring is initiated, and within the preset first monitoring duration, the user's current energy storage battery discharge depth setting value is periodically or event-triggered. If, at the end of the first monitoring period, it is detected that the user's current energy storage battery discharge depth setting value has not been adjusted to be less than or equal to the preset safety value, a second warning message will be sent to the corresponding user. The second warning message is stronger or more urgent than the first warning message. If, within the first monitoring period, it is detected that the user's current energy storage battery discharge depth setting has been adjusted to less than or equal to the preset safety value, a confirmation message will be sent to the corresponding user to inform them that the setting has been completed.

[0021] This invention provides a method for early warning of the discharge depth of energy storage batteries. Through a series of automated steps, including initial warning, status monitoring, secondary reminder, and completion confirmation, a mandatory closed loop of user operation guidance is formed. This not only significantly improves the user reach rate of protection suggestions and the clarity of operation guidance, but also realizes the tracking and supervision of user execution through a status feedback mechanism. It effectively solves the pain point that traditional single reminders are easily ignored, thereby significantly improving the actual execution rate of preventive measures and fundamentally reducing the risk of battery failure in winter due to improper settings from the user's perspective.

[0022] In one alternative implementation, the method further includes: When the current date is determined to be the end of the preset season, a recovery prompt message is generated and sent to the user to remind the user to restore the energy storage battery discharge depth to the normal operating value.

[0023] The present invention provides a method for early warning of the discharge depth of an energy storage battery. By actively notifying users to restore the normal discharge depth setting of the battery after the winter, the protection strategy is dynamically closed-loop managed, so that users do not have to sacrifice the available battery capacity for a long time and ensure the economical operating efficiency of the system during non-winter periods.

[0024] In a second aspect, the present invention provides a device for early warning of the discharge depth of an energy storage battery, the device comprising: The data acquisition module is used to acquire the current date and the geographical location information of the energy storage power station; the geographical location information includes at least latitude information; The early warning judgment module is used to determine whether the early warning triggering conditions are met based on the comparison results between latitude information and preset latitude threshold, as well as the comparison results between the current date and preset season start time. The early warning generation and communication module is used to trigger an early warning of the discharge depth of the energy storage battery in the energy storage power station if the early warning triggering conditions are met, and to send graded early warning information to the user.

[0025] 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 energy storage battery discharge depth warning method of the first aspect or any corresponding embodiment described above.

[0026] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions for causing a computer to execute the energy storage battery discharge depth warning method of the first aspect or any corresponding embodiment described above.

[0027] Fifthly, the present invention provides a computer program product, including computer instructions, which are used to cause a computer to execute the energy storage battery discharge depth early warning method of the first aspect or any corresponding embodiment described above.

Detailed Implementation

[0030] 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.

[0031] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] As an optional application scenario of this invention, such as Figure 1 As shown, this is an embodiment of the Energy Storage Management System (SEMS platform) of the present invention. The system includes a cloud platform 101, a terminal device 102, and a user APP / display screen 103; wherein: The cloud platform integrates modules such as historical meteorological database, 6G / 8B IoT synchronous data interface, early warning planning engine and frequency meter, and is responsible for core data processing and early warning decision-making.

[0034] Terminal equipment forms the sensing and execution layer of the energy storage management system, including: GPS module / barometer, used to automatically measure and record the latitude, longitude and altitude of the energy storage power station; A real-time clock used to provide the current date; The BMS master controller is the direct execution unit for battery management and the execution end of the SEMS platform. It is used to receive warning instructions from the cloud platform, including altitude, current date, and other information.

[0035] Ultimately, warning instructions and interactive information are presented to users through the user's APP / display screen, guiding or directly adjusting the battery discharge depth by executing the DOD setting channel, thus forming a complete closed-loop system from cloud-based intelligent decision-making to terminal device execution and user interaction feedback.

[0036] Lithium-ion batteries, especially lithium iron phosphate batteries, experience a significant performance degradation at low temperatures (typically below 5°C), with a decrease in the rate of internal chemical reactions and an increase in internal resistance.

[0037] Existing battery winter protection solutions have significant drawbacks: 1. Single-latitude model: This model divides climate zones solely based on latitude (e.g., issuing warnings in September for all areas above 30°N). However, the arrival time of winter varies greatly across different altitudes at the same latitude (e.g., the Tibetan Plateau vs. the East China Plain), leading to: (1) The warning for high-altitude users came too late (the battery was already frozen); (2) Frequent false alarms for low-altitude users (interfering with user experience).

[0038] 2. Static time threshold: Fixed date triggering cannot adapt to climate change and extreme weather; 3. Lack of quantitative correction: There is no altitude compensation mechanism, and users in high-altitude areas still need to make manual adjustments.

[0039] How to identify the risk of batteries entering a deep discharge state before the actual arrival of cold weather? How to implement differentiated and precise early warnings based on the actual climate characteristics of different regions (especially the timing and intensity of winter arrival) to improve user experience? How to proactively and effectively guide users to complete the correct protective settings and improve the execution rate of preventive measures? How to significantly reduce equipment failures and after-sales support pressure caused by battery depletion in winter, thereby improving the reliability of the system throughout its entire life cycle, are urgent problems that need to be solved.

[0040] To address the aforementioned issues, this invention provides a method for early warning of battery discharge depth, which deeply integrates three factors: geographical location latitude, altitude, and seasonal judgment. Its core lies in the intelligent triggering mechanism of latitude + calendar and the closed-loop management process of reminder + verification, which transforms the battery protection strategy from "passive response to faults" to "active risk prevention," thereby fundamentally avoiding battery freezing accidents and extending battery life.

[0041] According to an embodiment of the present invention, an embodiment of a method for early warning of the discharge depth of an energy storage battery 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.

[0042] This embodiment provides a method for early warning of the discharge depth of an energy storage battery, which can be used in the aforementioned electronic devices or terminal devices, wherein an energy storage management system (SEMS platform) is installed on the electronic devices or terminal devices. Figure 2 This is a flowchart of a method for early warning of the depth of discharge of an energy storage battery according to an embodiment of the present invention, as shown below. Figure 2 As shown, the process includes the following steps: Step S201: Obtain the current date and the geographical location information of the energy storage power station; the geographical location information includes at least latitude information.

[0043] The SEMS platform acquires and stores the precise geographical location of the energy storage power station (such as the latitude and longitude information of the power station used to characterize the climate zone) filled in by the user when creating the profile, and also acquires the current real-time date information.

[0044] Step S202: Based on the comparison results of latitude information and preset latitude threshold, and the comparison results of current date and preset season start time, determine whether the warning triggering conditions are met.

[0045] Specifically, the SEMS platform has a built-in logic judgment module that continuously runs the following comparison operations: The acquired latitude information is compared with a preset latitude threshold, and the current date is compared with a preset season start time. Based on the results of the two comparisons, a comprehensive judgment is made as to whether the warning triggering conditions are met.

[0046] In step S203, if the warning triggering conditions are met, a warning of the discharge depth of the energy storage battery in the energy storage power station is triggered, and a graded warning message is sent to the user.

[0047] Specifically, the depth of discharge (DOD) warning for energy storage batteries is a proactive and preventative intelligent notification mechanism. It refers to an early risk warning signal issued by the system when the battery is about to face damage risk but has not yet experienced an actual failure. The direct goal of this warning is to guide users to adjust the battery's DOD setting. Its fundamental purpose is to prevent energy storage batteries from suffering irreversible damage (such as "freezing to death") due to over-discharge in upcoming harsh environments (such as low winter temperatures).

[0048] After triggering the alert, a primary alert message containing specific operation instructions is first sent to the user through a preset channel; then, the system automatically starts monitoring the user's settings status and checks them within a preset monitoring period; if the user still has not adjusted the settings as required by the end of the period, a secondary alert message with stronger warning is automatically sent; otherwise, if the system detects that the user has completed the correct settings, a confirmation message is sent to form an operation loop.

[0049] The energy storage battery discharge depth early warning method provided in this embodiment realizes the transformation from passive monitoring to active prediction by integrating real-time date and power station latitude information and intelligently comparing it with preset spatiotemporal thresholds.

[0050] This embodiment provides a method for early warning of the discharge depth of an energy storage battery, which can be used in the aforementioned electronic devices or terminal devices, wherein an energy storage management system (SEMS platform) is installed on the electronic devices or terminal devices. Figure 3 This is a flowchart of a method for early warning of the depth of discharge of an energy storage battery according to an embodiment of the present invention, as shown below. Figure 3 As shown, the process includes the following steps: Step S301: Obtain the current date and the geographical location information of the energy storage power station; the geographical location information includes at least latitude. For details, please refer to [link to relevant documentation]. Figure 2 Step S201 of the illustrated embodiment will not be described again here.

[0051] Step S302: Based on the comparison results of latitude information and preset latitude threshold, and the comparison results of current date and preset season start time, determine whether the warning triggering conditions are met.

[0052] Specifically, such as Figure 5 As shown, the geographic location information also includes altitude information (i.e., altitude); step S302 above includes: Step S3021: If the latitude information is greater than or equal to the preset latitude threshold, and the current date reaches or exceeds the preset season start time, then the warning triggering condition is determined to be met.

[0053] For example: Latitude determination: Determine whether the absolute value of the latitude of the energy storage power station is greater than or equal to 30°. This 30° latitude threshold covers most regions where winter temperatures remain below 5°C.

[0054] Time determination: Based on hemispheres_mapping (hemisphere mapping relationship or hemisphere determination rule): If the energy storage power station is in the Northern Hemisphere and the current month is September (or September 1); if the energy storage power station is in the Southern Hemisphere and the current month is March (or March 1).

[0055] Logical intersection: When both the latitude and time judgments are satisfied, the warning triggering conditions are met, and the warning process is then triggered.

[0056] Step S3022: If the latitude information is greater than or equal to the preset latitude threshold, and the current date reaches or exceeds the preset season start time, the preset season start time is corrected based on the preset correction rules and altitude information; if the current date reaches or exceeds the corrected season start time, it is determined that the warning triggering condition is met.

[0057] To address the shortcomings of related technologies that ignore the impact of altitude on the timing of winter arrival, this embodiment introduces altitude as a key parameter based on latitude determination, establishing a two-dimensional "latitude-altitude" early warning model to achieve more scientific and accurate early warning.

[0058] The core of this embodiment lies in: constructing a latitude-altitude-climate zone mapping relationship, using altitude as a correction factor, dynamically adjusting the early warning trigger time, realizing three-dimensional climate perception, and making the early warning signal more consistent with the actual geographical environment of the energy storage power station.

[0059] like Figure 6 As shown, the specific process of this step includes: While obtaining the latitude and longitude information of the energy storage power station, the altitude of the energy storage power station should also be obtained. The altitude can be obtained through any of the following methods: Users can manually input or obtain the data from the map API when building an energy storage power station; SEMS integrates a GPS module / barometer to automatically measure and record the altitude of the energy storage power station.

[0060] First, the basic triggering conditions remain unchanged: if the latitude information is greater than or equal to the preset latitude threshold, and the current date reaches or exceeds the preset season start time, then the warning triggering conditions are determined to be met. Next, determine whether the altitude is higher than the preset altitude threshold (e.g., 500 meters). If the altitude is higher than the preset altitude threshold, it is determined to be a high-altitude area, and the final warning trigger time is determined according to step a1 or step a2 below.

[0061] In some optional implementations, step S3022 above includes: Step a1: Calculate the time advance based on the difference between the altitude information and the preset altitude threshold, and the preset altitude-time advance correspondence; advance the preset season start time by the time advance to obtain the corrected warning trigger time.

[0062] Specifically, firstly, the difference between the actual altitude of the energy storage power station and the preset altitude threshold is calculated. Then, based on the preset "altitude-time advance" correspondence table, the difference is mapped to a specific time advance. Finally, the original seasonal start time is subtracted from this time advance, thereby generating an advanced and corrected warning trigger time that is tailored to the climate characteristics of high-altitude areas.

[0063] The established altitude-time lead correspondence table is shown in Table 1 below: Table 1. Correspondence between Altitude and Time Lead Amount

[0064] The revised formula for calculating the warning trigger time is as follows: (1); or: (2); in: The final warning trigger time, The altitude correction factor is the time lead time related to the altitude difference, a parameter or calculated value used to quantify the impact of altitude on the advance time of warning triggering.

[0065] For example, for every 1,000 meters increase in altitude, the warning trigger time is brought forward by half a month.

[0066] Step a2: Based on the latitude and altitude information, query the preset latitude-altitude-warning trigger time mapping table to directly obtain the corresponding corrected warning trigger time.

[0067] Example content is shown in Table 2 below: Table 2 Latitude-Altitude-Warning Trigger Time Mapping Table

[0068] Final trigger determination: Taking into account the current month, latitude zone, and altitude, the final warning trigger time is determined by looking up a table or by calculation.

[0069] Step S303: If the warning triggering conditions are met, a depth of discharge warning for the energy storage battery in the energy storage power station is triggered, and tiered warning information is sent to the user. For details, please refer to [link to relevant documentation]. Figure 2Step S203 of the illustrated embodiment will not be described again here.

[0070] The energy storage battery discharge depth early warning method provided in this embodiment integrates geographical location (latitude and altitude) and calendar time. The system can intelligently predict the arrival of the winter low-temperature period and proactively issue early warnings before potential battery damage, upgrading battery protection from "passive response" to "proactive prevention," greatly improving battery reliability and lifespan. The latitude-based judgment logic makes the alert service more accurate, avoiding indiscriminate alarms for global users, reducing interference with users in low-latitude or warm-winter regions, and enhancing the practicality of the function.

[0071] This embodiment provides a method for early warning of the discharge depth of an energy storage battery, which can be used in the aforementioned electronic devices or terminal devices, wherein an energy storage management system (SEMS platform) is installed on the electronic devices or terminal devices. Figure 4 This is a flowchart of a method for early warning of the depth of discharge of an energy storage battery according to an embodiment of the present invention, as shown below. Figure 4 As shown, the process includes the following steps: Step S401: Obtain the current date and the geographical location information of the energy storage power station; the geographical location information includes at least latitude. For details, please refer to [link to relevant documentation]. Figure 3 Step S301 of the illustrated embodiment will not be described again here.

[0072] Step S402: Based on the comparison between latitude information and a preset latitude threshold, and the comparison between the current date and a preset season start time, determine whether the warning triggering conditions are met. For details, please refer to [link to relevant documentation]. Figure 3 Step S302 of the illustrated embodiment will not be described again here.

[0073] In step S403, if the warning triggering conditions are met, a warning of the discharge depth of the energy storage battery in the energy storage power station is triggered, and a graded warning message is sent to the user.

[0074] Specifically, such as Figure 5 and Figure 6 As shown, step S403 above includes: In step S4031, in response to the discharge depth warning of the energy storage battery, a first warning message is sent to the corresponding user through at least one preset communication channel. The first warning message includes suggestions and operation instructions for adjusting the battery discharge depth to a preset safety value.

[0075] For example, after an alert is triggered, the SEMS platform sends a friendly notification to the user via mobile application (APP) push notification and email, with the following content template: [Winter Battery Maintenance Reminder] Dear customer, based on the climate characteristics of your energy storage station's location, winter is approaching. To ensure stable operation of your energy storage batteries at low temperatures, we recommend setting the maximum depth of discharge (DOD) of your energy storage batteries to the preset safe value of 90% or lower. This will reserve the necessary charge for the batteries and effectively prevent the risk of low-temperature power depletion.

[0076] Step S4032: After sending the first warning information, start status monitoring, and periodically or event-triggeredly obtain the user's current energy storage battery discharge depth setting value within a preset first monitoring period.

[0077] Specifically, if the SEMS platform has the ability to remotely read the user's current DOD settings, the monitoring program will be started, and within a preset first monitoring period (e.g., 72 hours), the user's current energy storage battery discharge depth setting value will be obtained periodically or by event triggering.

[0078] Step S4033: If, at the end of the first monitoring period, it is detected that the user's current energy storage battery discharge depth setting value has not been adjusted to less than or equal to the preset safety value, then a second warning message is sent to the corresponding user. The second warning message is stronger or more urgent than the first warning message.

[0079] Specifically, if the system detects that a user has not set the DOD to ≤90% within a certain period of time (such as 72 hours) after receiving the reminder, the system will automatically send a second reminder, which may be more urgent and emphasize the potential risks.

[0080] Step S4034: If, within the first monitoring period, it is detected that the user's current energy storage battery discharge depth setting value has been adjusted to less than or equal to the preset safety value, a confirmation message is sent to the corresponding user to inform the user that the setting has been completed.

[0081] Specifically, if the system detects that the user has completed the setup, it can send a confirmation message to provide positive feedback to the user.

[0082] Step S404: When it is determined that the current date has reached the preset end time of the season, a recovery prompt message is generated and sent to the user to prompt the user to restore the discharge depth of the energy storage battery to the normal operating value.

[0083] When the SEMS platform determines that winter has ended (e.g., when the Northern Hemisphere enters April of the following year), it can remind the user again that it is safe to restore the DOD setting to a deeper range (e.g., 100%) to maximize daily electricity economy.

[0084] The energy storage battery discharge depth early warning method provided in this embodiment transforms the battery protection strategy from "passive fault response" to "proactive risk prevention," fundamentally avoiding battery freezing accidents, extending battery life, and preventing problems before they occur. It significantly reduces the need for on-site technical support, equipment repair, and replacements due to battery issues in winter, directly improving product profit margins and drastically reducing after-sales costs. The proactive, considerate, and precise reminder service enhances user stickiness, demonstrating the product's intelligence level and the brand's depth of care for users, improving user experience and the brand's intelligent image. The latitudinal logic has good global adaptability, the algorithm is simple and reliable, has low computational load, and is easy to deploy on various SEMS platforms, possessing global adaptability. Through a closed-loop design of "monitoring-reminder-verification," it ensures the effective implementation of protective measures, rather than merely a formality, forming a management closed loop.

[0085] As one or more specific application embodiments of the present invention, combined with Figure 6 The method for early warning of the depth of discharge of energy storage batteries provided by the present invention will be further described in detail, such as... Figure 6 As shown, the specific process is as follows: Step 1: Data Acquisition and Condition Judgment 1. Data Input: The SEMS platform acquires and stores the precise geographical location (latitude and longitude) of the power station filled in by the user when creating the file.

[0086] 2. Triggering logic: SEMS has a built-in logic judgment module that continuously runs the following judgments: Latitude determination: Determine if the absolute value of the power station's latitude is greater than or equal to 30°. This threshold covers most areas where winter temperatures remain below 5°C.

[0087] Time determination: Based on hemispheres_mapping: If the power station is in the Northern Hemisphere, and the current month is September (or September 1st). If the power plant is in the Southern Hemisphere, and the current month is March (or March 1st).

[0088] 3. Logical intersection: When both latitude and time conditions are met, the early warning process is triggered.

[0089] To address the shortcomings of related technologies that ignore the impact of altitude on the timing of winter arrival, this embodiment introduces altitude as a key parameter based on latitude determination, establishing a two-dimensional "latitude-altitude" early warning model to achieve more scientific and accurate early warning.

[0090] The core of this embodiment lies in: constructing a latitude-altitude-climate zone mapping relationship, using altitude as a correction factor, dynamically adjusting the early warning trigger time, realizing three-dimensional climate perception, and making the early warning signal more consistent with the actual geographical environment of the energy storage power station.

[0091] like Figure 6 As shown, the specific process of this step includes: While obtaining the latitude and longitude information of the energy storage power station, the altitude of the energy storage power station should also be obtained. The altitude can be obtained through any of the following methods: Users can manually input or obtain the data from the map API when building an energy storage power station; SEMS integrates a GPS module / barometer to automatically measure and record the altitude of the energy storage power station.

[0092] 4. Trigger logic optimization: First, the basic triggering conditions remain unchanged: if the latitude information is greater than or equal to the preset latitude threshold, and the current date reaches or exceeds the preset season start time, then the warning triggering conditions are determined to be met. Next, it is determined whether the altitude is higher than a preset altitude threshold (e.g., 500 meters). If the altitude is higher than the preset altitude threshold, it is determined to be a high-altitude area.

[0093] Early warning triggering mechanism, for example: (1) For every 1,000 meters increase in altitude, the warning trigger time is brought forward by half a month.

[0094] (2) Establish a latitude-altitude-early warning trigger time mapping table, for example: Table 2 Latitude-Altitude-Warning Trigger Time Mapping Table

[0095] Final trigger determination: Taking into account the current month, latitude zone, and altitude, the final warning trigger time is determined by looking up a table or by calculation.

[0096] Step Two: Tiered Early Warning and User Guidance Initial alert: Upon triggering, SEMS sends a friendly notification to the user via mobile application (APP) push notification and email, with the following template: [Winter Battery Maintenance Reminder] Dear customer, based on the climate characteristics of your energy storage station's location, winter is approaching. To ensure stable operation of the energy storage battery at low temperatures, we recommend setting the maximum depth of discharge (DOD) of the energy storage battery to 90% or lower. This will reserve the necessary charge for the energy storage battery and effectively prevent the risk of low-temperature power depletion.

[0097] Step 3 (Optional Enhancement): Status Verification and Secondary Reminder 1. Status monitoring: If the SEMS platform has the ability to remotely read the user's current DOD settings, then start the monitoring program.

[0098] 2. Closed-loop feedback: If the system detects that the user has not set DOD to ≤90% within a certain period of time (e.g., 72 hours) after receiving the reminder, it will automatically send a second reminder, which may be more urgent and emphasize the potential risks.

[0099] If the system detects that the user has completed the setup, a confirmation message can be sent to provide positive feedback.

[0100] Step 4: Seasonal End and Recovery Tips: When the system determines that winter has ended (e.g., when the Northern Hemisphere enters April of the following year), it can remind the user again that it is safe to restore the DOD setting to a deeper range (e.g., 100%) to maximize daily electricity economy.

[0101] The energy storage battery discharge depth early warning method provided in this embodiment has the following beneficial effects: 1. Proactive Intelligent Protection: By integrating geographical location (latitude) and calendar time, the system can intelligently predict the arrival of the winter low temperature period and proactively issue a warning before the battery may be damaged, upgrading battery protection from "passive response" to "proactive prevention", which greatly improves the reliability and life of the battery.

[0102] 2. Reduce after-sales costs and customer complaints: It fundamentally reduces the number of failures caused by deep battery discharge in winter, shortens the after-sales service cycle, reduces on-site maintenance costs, and significantly improves customer satisfaction and brand reputation.

[0103] 3. Intelligent and humanized guidance: By providing clear operation suggestions to users at appropriate times through direct channels such as APP pop-ups and emails, the implementation rate of preventive measures is greatly improved, reflecting the product's humanistic care and intelligent level.

[0104] 4. Adaptability and Precision: Latitude-based judgment logic makes the alert service more accurate, avoids indiscriminate alarms for global users, reduces interference for users in low-latitude or warm winter regions, and improves the usability of the function.

[0105] 5. Enhanced system robustness: The solution considers whether to automatically detect logical branches of user DOD settings, and supports automated secondary reminders and scenarios that rely on manual user operation, thus enhancing the adaptability and robustness of the method in practical applications.
