Technical Field
[0001] This application relates to the field of battery charging control technology, and in particular to battery charging control methods, charging piles, charging cabinets and charging platforms. Background Technology
[0002] With the widespread adoption of electric vehicles such as electric cars and electric bicycles, battery charging technology has become a research hotspot. Currently, the determination of a fully charged battery is inaccurate for different types of batteries. Therefore, there is an urgent need for a charging control method that can accurately determine the battery's full charge status, improve charging efficiency, and adapt to different battery types. Summary of the Invention
[0003] The main purpose of this application is to provide a battery charging control method, a charging pile, a charging cabinet, and a charging platform, which aim to improve charging efficiency.
[0004] To achieve the above objectives, this application proposes a battery charging control method, which includes the following steps: When the battery enters the float charging stage, obtain the real-time charging power of the battery; The real-time charging power is matched with multiple full-charge stop parameters to obtain the matched full-charge stop parameters, which include the full-charge stop power range and the remaining float charging time. If the real-time charging power is not greater than the maximum value of the matched full charge stop power range, and the float charging time is greater than the remaining float charging time, then the battery is determined to be fully charged, and charging of the battery is stopped. If the real-time charging power is greater than the maximum value of the matched full charge stop power range, or if the float charging time is not greater than the remaining float charging time, then it is determined that the battery is not fully charged, and the battery continues to be charged.
[0005] In one embodiment, the step of obtaining the real-time charging power of the battery includes: The real-time charging voltage and real-time charging current of the battery are obtained; the real-time charging power is calculated using the power register of the power metering chip based on the real-time charging voltage and the real-time charging current.
[0006] In one embodiment, the plurality of fill-to-stop parameters include a first fill-to-stop parameter and a second fill-to-stop parameter; The first full charge stop parameters include the first full charge stop power range and the first remaining float charge time; The second full charge stop parameter includes a second full charge stop power range and a second remaining float charge time; the maximum value of the second full charge stop power range is less than the minimum value of the first full charge stop power range. In one embodiment, the matching of real-time charging power with multiple full-charge stop parameters to obtain the matched full-charge stop parameters includes: If the real-time charging power is within the range of the corresponding full charge stop parameter, the matching is confirmed to be successful.
[0007] In one embodiment, before performing the step of obtaining the real-time charging power of the battery when the battery enters the float charging stage, the battery charging control method further includes: Obtain charging curves for different types of batteries, derive multiple full-charge stop parameters based on the charging curves, and store them.
[0008] In one embodiment, the battery charging control method further includes the following steps: The real-time charging power is matched with multiple disconnection and stop parameters to obtain the matched disconnection and stop parameters, which include a disconnection and stop power range and a preset detection time. If the real-time charging power is not greater than the maximum value of the matched disconnection stop power range, and the detection time is greater than the preset detection time, then it is determined that the charging interface is disconnected or the charging power is abnormal. If the real-time charging power is greater than the maximum value of the matched disconnection stop power range, or if the detection time is not greater than the preset detection time, then it is determined that the charging interface is not disconnected and the charging power is not abnormal.
[0009] In one embodiment, the plurality of disconnection stop parameters include a first disconnection stop parameter and a second disconnection stop parameter; The first disconnection stop parameters include a first disconnection stop power range and a first preset detection time; The second disconnection stop parameter includes a second disconnection stop power range and a second preset detection time; the maximum value of the second disconnection stop power range is less than the minimum value of the first disconnection stop power range.
[0010] In one embodiment, this application also provides a charging pile, which is equipped with an energy metering chip. The charging pile implements the battery charging control method described above through the energy metering chip and the control program.
[0011] In one embodiment, this application also provides a charging cabinet, the charging cabinet having the power metering chip inside, the charging cabinet implementing the battery charging control method described above through the power metering chip and control program.
[0012] In one embodiment, this application also provides a charging platform, the charging platform including: a memory, a processor, and a battery charging control program stored in the memory and executable on the processor, the battery charging control program being configured to implement the steps of the battery charging control method as described above.
[0013] This invention pre-sets multiple sets of charging stop parameters, each set including a charging stop power range and a corresponding remaining float charging time. The charging stop power range defines the power range, and the remaining float charging time specifies the time required to continue float charging within that power range. Different charging stop power ranges correspond to different remaining float charging times, thus achieving dynamic adjustment and avoiding judgment errors caused by fixed parameters.
[0014] After the battery enters the float charging stage, the charging power is acquired in real time and matched with various sets of parameters to determine the applicable power range for stopping full charge and the remaining float charging time. Simultaneously, the float charging time is continuously recorded from the start of the float charging stage. The float charging time can be the length of time counted from the start of the float charging stage. By monitoring the charging power in real time and matching the corresponding full charge stopping parameters, the battery can be determined to be fully charged when any stage's criteria are met. This caters to the full charge determination needs of different battery types, significantly improving the accuracy of full charge determination.
[0015] Based on this, the remaining float charging time is dynamically adjusted according to the real-time charging power: when the charging power is high, a longer float charging time is set to ensure the battery is fully charged; when the charging power is low, a shorter float charging time is set to speed up the charging process, thereby effectively shortening the overall charging time while ensuring a full charge. Furthermore, this method can pre-store matching full-charge stop parameters based on the charging curves of different battery types, flexibly adapting to various battery specifications and avoiding problems such as misjudgment, overcharging, or undercharging caused by fixed parameters.
[0016] In practice, if the real-time charging power exceeds the maximum value of the matched full-charge stop power range, or the float charging time is not greater than the remaining float charging time, the battery is determined not to be fully charged, and charging continues. This step ensures continuous charging of batteries that have not yet met the full-charge criteria, guaranteeing sufficient charge. Furthermore, the dynamic determination of real-time power and float charging time ensures that charging control aligns with the power variation patterns during the battery's float charging phase, preventing insufficient charging due to indiscriminate charging stoppages.

[0020] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0021] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.
[0022] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.
[0023] Traditional battery charging control methods typically employ staged charging strategies such as constant current charging, constant voltage charging, and float charging. In the final stage of charging, float charging is usually used to supplement the battery and ensure it is fully charged. However, this method has the following three shortcomings in practical applications: First, the determination of full charge is inaccurate. Traditional methods usually use a fixed charging time or a fixed voltage threshold to determine whether the battery is fully charged. However, different types, capacities, and aging levels of batteries have significant differences in charging characteristics during the float charging stage. Fixed parameters are difficult to adapt to all situations, which can easily lead to stopping charging before the battery is fully charged or overcharging, affecting battery life.
[0024] Secondly, charging efficiency is low. To ensure the battery is fully charged, traditional methods typically set a long float charging time, resulting in excessively long charging times, which affects user experience and the efficiency of charging equipment.
[0025] Third, it lacks adaptability to different types of batteries. Different types of batteries (such as lithium batteries and lead-acid batteries) have different charging characteristics, and traditional methods are difficult to dynamically adjust charging parameters according to battery type.
[0026] In one feasible implementation, refer to Figure 1 This application provides a battery charging control method, including the following steps: S10: When the battery enters the float charging stage, it obtains the real-time charging power of the battery. S20, Based on the real-time charging power, match with multiple full charge stop parameters to obtain the matched full charge stop parameters, wherein the full charge stop parameters include the full charge stop power range and the remaining float charging time; S30, when the real-time charging power is not greater than the maximum value of the matched full charge stop power range, and the float charging time is greater than the remaining float charging time, the battery is determined to be fully charged, and charging of the battery is stopped. If the real-time charging power is greater than the maximum value of the matched full charge stop power range, or if the float charging time is not greater than the remaining float charging time, then it is determined that the battery is not fully charged, and the battery continues to be charged.
[0027] This invention pre-sets multiple sets of charging stop parameters, each set including a charging stop power range and a corresponding remaining float charging time. The charging stop power range defines the power range, and the remaining float charging time specifies the time required to continue float charging within that power range. Different charging stop power ranges correspond to different remaining float charging times, thus achieving dynamic adjustment and avoiding judgment errors caused by fixed parameters.
[0028] After the battery enters the float charging stage, the charging power is acquired in real time and matched with various sets of parameters to determine the applicable power range for stopping full charge and the remaining float charging time. Simultaneously, the float charging time is continuously recorded from the start of the float charging stage. The float charging time can be the length of time counted from the start of the float charging stage. By monitoring the charging power in real time and matching the corresponding full charge stopping parameters, the battery can be determined to be fully charged when any stage's criteria are met. This caters to the full charge determination needs of different battery types, significantly improving the accuracy of full charge determination.
[0029] Based on this, the remaining float charging time is dynamically adjusted according to the real-time charging power: when the charging power is high, a longer float charging time is set to ensure the battery is fully charged; when the charging power is low, a shorter float charging time is set to speed up the charging process, thereby effectively shortening the overall charging time while ensuring a full charge. Furthermore, this method can pre-store matching full-charge stop parameters based on the charging curves of different battery types, flexibly adapting to various battery specifications and avoiding problems such as misjudgment, overcharging, or undercharging caused by fixed parameters.
[0030] In practice, if the real-time charging power exceeds the maximum value of the matched full-charge stop power range, or the float charging time is not greater than the remaining float charging time, the battery is determined not to be fully charged, and charging continues. This step ensures continuous charging of batteries that have not yet met the full-charge criteria, guaranteeing sufficient charge. Furthermore, the dynamic determination of real-time power and float charging time ensures that charging control aligns with the power variation patterns during the battery's float charging phase, preventing insufficient charging due to indiscriminate charging stoppages.
[0031] In one feasible implementation, the step of obtaining the real-time charging power of the battery includes: The system acquires the battery's real-time charging voltage and current; and calculates the real-time charging power using the power register of the energy metering chip based on these values. The energy metering chip includes a voltage register, a current register, a power register, and an energy register. The real-time charging power is obtained from the power register of the energy metering chip.
[0032] The formula for calculating real-time charging power is: P=U×I×cosφ, where P is the real-time charging power, U is the real-time charging voltage, I is the real-time charging current, and cosφ is the power factor. This formula is used for calculating real-time power when powered by mains electricity.
[0033] In one feasible implementation, the plurality of fill stop parameters include a first fill stop parameter and a second fill stop parameter; The first full charge stop parameters include the first full charge stop power range and the first remaining float charge time; The second full charge stop parameter includes a second full charge stop power range and a second remaining float charge time; the maximum value of the second full charge stop power range is less than the minimum value of the first full charge stop power range.
[0034] This invention achieves full coverage of batteries with different float charging power levels by setting a multi-level gradient structure with progressively decreasing power range, and can adapt to the float charging characteristics of different battery types such as lead-acid batteries and lithium batteries.
[0035] In addition, each parameter has an independent correspondence between the "power range for stopping full charge" and the "remaining float charging time", which enables matching for different float charging powers. This allows batteries with different float charging power levels to obtain a judgment standard that is compatible with them, improving the accuracy of battery full charge determination and avoiding overcharging or undercharging.
[0036] Multiple fill-to-stop parameters can be added or removed as needed. For example, there can be 3, 4, or 5 fill-to-stop parameters, or even more than 5.
[0037] In one feasible implementation, there are four full-fill stop parameters, including a first full-fill stop parameter, a second full-fill stop parameter, a third full-fill stop parameter, and a fourth full-fill stop parameter. The first full charge stop parameters include the first full charge stop power range and the first remaining float charge time; The second full charge stop parameter includes a second full charge stop power range and a second remaining float charge time; the maximum value of the second full charge stop power range is less than the minimum value of the first full charge stop power range. The third full charge stop parameter includes the third full charge stop power range and the third remaining float charge time; the maximum value of the third full charge stop power range is less than the minimum value of the second full charge stop power range; The fourth full charge stop parameter includes the fourth full charge stop power range and the fourth remaining float charge time; the maximum value of the fourth full charge stop power range is less than the minimum value of the third full charge stop power range.
[0038] In one feasible implementation, the first full charge stop power range is 35W to 60W, and the first remaining float charge time is 60 minutes. The second full charge stop power range is 25W to 35W, and the second remaining float charging time is 40 minutes; The third fully charged power range is 10W to 25W, and the third remaining float charging time is 20 minutes. The fourth full charge stop power range is 0 to 10W, and the fourth remaining float charge time is 10 minutes.
[0039] In specific judgments, corresponding parameters are matched based on the real-time charging power. For example, if the real-time charging power is 42W, the first parameter for stopping charging when full is reached is matched; if it is 30W, the second parameter for stopping charging when full is reached is matched, and so on. After matching, the power condition and the time condition are compared simultaneously. If the real-time charging power is 42W and the float charging time reaches 65 minutes, since 42W does not exceed 60W and 65 minutes is greater than 60 minutes, both conditions are met, the battery is determined to be fully charged, and charging is stopped. If the real-time charging power is also 42W, but the float charging time is only 50 minutes, then although the power condition is met, the float charging time is no more than 60 minutes, so the battery is determined to be not fully charged and charging continues. If the real-time charging power is 65W and the float charging time is 65 minutes, the power condition is not met (65W>60W). Even if the float charging time meets the requirements, it is still determined that it is not fully charged and charging continues.
[0040] The above judgment logic is based on the fact that charging power reflects the degree to which the battery is close to being fully charged; the lower the power, the closer it is to being fully charged. However, judging solely by power may be affected by short-term fluctuations and produce errors. Therefore, a dual judgment is made by combining float charging time to ensure the accuracy of the judgment. At the same time, different float charging times are configured for different power ranges. The higher the power, the longer the float charging time required, and the lower the power, the shorter the float charging time required, thus achieving dynamic optimization.
[0041] In one embodiment, reference is made to Figure 3 According to the charging curve of lead-acid batteries, the float charging stage begins when the charging power reaches 75W. If the detected real-time charging power is 70W, the detection continues until the real-time charging power falls within the first full-charge stop power range of the corresponding first full-charge stop parameter (e.g., 35W to 60W), at which point the matching is confirmed to be successful.
[0042] Taking a charging process as an example: At the start of the float charging phase, the real-time charging power is 48W, matching the first power range (35W–60W) before full charge is stopped, and the first remaining float charging time is set to 60 minutes. As charging progresses, the battery gradually fills up, and the power gradually decreases. After 10 minutes, the power drops to 45W, still within the first full charge power range. The cumulative float charging time is 10 minutes, not exceeding 60 minutes, and charging continues. After 30 minutes, the power drops to 32W, entering the second full charge stop power range (25W–35W). The second remaining float charging time is 40 minutes. The cumulative float charging time is 30 minutes, not exceeding 40 minutes, and charging continues. After 50 minutes, the power drops to 18W, entering the third full charge stop power range (10W–25W). The remaining float charging time is 20 minutes, and the cumulative float charging time is 50 minutes. Since the total float charging time is greater than 20 minutes and 18W does not exceed 25W, both conditions are met, the battery is determined to be fully charged, and charging stops.
[0043] The entire float charging phase lasts 50 minutes, saving 10 minutes compared to the fixed 60-minute float charging time, effectively improving charging efficiency.
[0044] In one feasible implementation, the matching of real-time charging power with multiple full-charge stop parameters to obtain the matched full-charge stop parameters includes: If the real-time charging power is within the range of the corresponding full charge stop parameter, the matching is confirmed to be successful.
[0045] The real-time data acquisition and matching operation mode can track the power decay process of different battery float charging stages, so that the parameter matching is consistent with the actual float charging characteristics of the battery. It effectively adapts to the float charging power changes of different battery types such as lead-acid and lithium batteries, and improves the adaptability of the charging control method to multiple battery types.
[0046] In one feasible implementation, refer to Figure 2 Before performing the step of obtaining the real-time charging power of the battery when the battery enters the float charging stage, the battery charging control method further includes: S01, obtain the charging curves of different types of batteries, obtain multiple full-charge stop parameters based on the charging curves, and store them.
[0047] Because of the diverse types of batteries, including lead-acid and lithium batteries, there are significant differences in charging power characteristics between different types and capacities. For example, lead-acid batteries may require a higher power range for stopping charging (35W to 60W) and a longer float charging time (e.g., 60 minutes), while lithium batteries may require a lower power range for stopping charging (0 to 10W) and a shorter float charging time (e.g., 10 minutes). Therefore, it is necessary to obtain the power change curves of various types of batteries during the float charging stage through experimental testing or theoretical analysis, in order to determine the optimal power-stopping parameters for each type of battery.
[0048] Specifically, refer to Figures 3 to 5 First, we obtain the charging curves of different types of batteries. These curves cover the power change characteristics of the entire process of constant current, constant voltage, and float charging. They can comprehensively reflect the complete power change law of various types of batteries from the start of charging to the end of float charging, providing raw data that fits the actual charging characteristics of the battery for setting the charging stop parameters.
[0049] Reference Figure 3 and Figure 4 Lead-acid battery charging includes three stages: constant current charging (CC), constant voltage charging (CV), and float charging. In the constant current stage, the current remains constant, the voltage rises slowly, and the charging power gradually increases. In the constant voltage stage, the voltage remains constant, the current drops rapidly, and the charging power decreases sharply. In the float charging stage, the voltage remains constant, the current is stable and low, and the charging power decreases slowly, remaining at a very small value.
[0050] Reference Figure 5 Lithium-ion battery charging includes three stages: constant current charging (CC), constant voltage charging (CV), and float charging. In the constant current charging stage, the current remains constant, the voltage rises steadily, and the power increases slowly. In the constant voltage charging stage, the battery gradually fills up, and the charging current decreases rapidly. In the float charging stage, the power remains at a very low and stable level.
[0051] Based on the obtained charging curves, the power range and required float charging time characteristics of different types of batteries during the float charging stage are extracted, and multiple full-charge stop parameters are obtained based on these characteristics. Each full-charge stop parameter corresponds to a type or variety of battery with specific float charging power characteristics, and each parameter includes the full-charge stop power range and the remaining float charging time.
[0052] Multiple fully charged stop parameters are pre-stored in the control module of the charging pile, charging cabinet, or charging platform to form a fully charged stop parameter library. The control module may include an energy metering chip. This allows for real-time retrieval and matching of the corresponding parameters during charging, enabling centralized management and rapid recall of fully charged stop parameters, thereby improving parameter matching efficiency and charging control response speed.
[0053] In one feasible implementation, the battery charging control method further includes the following steps: The real-time charging power is matched with multiple disconnection and stop parameters to obtain the matched disconnection and stop parameters, which include a disconnection and stop power range and a preset detection time. If the real-time charging power is not greater than the maximum value of the matched disconnection stop power range, and the detection time is greater than the preset detection time, then it is determined that the charging interface is disconnected or the charging power is abnormal. If the real-time charging power is greater than the maximum value of the matched disconnection stop power range, or if the detection time is not greater than the preset detection time, then it is determined that the charging interface is not disconnected and the charging power is not abnormal.
[0054] By setting disconnection stop parameters, the system can effectively identify situations such as a disconnected charging interface or abnormal charging power, promptly triggering alarms or stopping charging, thereby improving the safety of the charging process. For example, if a loose interface causes increased contact resistance and abnormally low charging power during charging, and this low power state persists for more than a preset detection time, the system will determine that the interface is disconnected or the power is abnormal, and will implement corresponding protection measures.
[0055] In one feasible implementation, the plurality of disconnection stop parameters include a first disconnection stop parameter and a second disconnection stop parameter; The first disconnection stop parameters include a first disconnection stop power range and a first preset detection time; The second disconnection stop parameter includes a second disconnection stop power range and a second preset detection time; the maximum value of the second disconnection stop power range is less than the minimum value of the first disconnection stop power range.
[0056] Multiple disconnect stop parameters can be added or removed as needed. For example, there can be 3, 4, or 5 full stop parameters, or even more than 5.
[0057] There are three disconnection and stop parameters, including a first disconnection and stop parameter, a second disconnection and stop parameter, and a third disconnection and stop parameter. The first disconnection stop parameters include a first disconnection stop power range and a first preset detection time. For example, the first disconnection stop power range is 5W to 9W, and the first preset detection time is 3 minutes.
[0058] The second disconnection stop parameter includes a second disconnection stop power range and a second preset detection time; the maximum value of the second disconnection stop power range is less than the minimum value of the first disconnection stop power range. For example, the second disconnection stop power range is 3W to 5W, and the second preset detection time is 2 minutes. The third disconnection stop parameter includes a third disconnection stop power range and a third preset detection time; the maximum value of the third disconnection stop power range is less than the minimum value of the second disconnection stop power range; for example, the third disconnection stop power range is 0 to 3W, and the third preset detection time is 30 seconds.
[0059] For example, in a specific scenario: after 20 minutes of charging, the charging port becomes loose, causing the power to drop sharply to 3W. At this point, the matching disconnection stop parameters are the third disconnection stop power range (0W to 3W) and the third preset detection time of 30 seconds. If the power drops below 3W for more than 30 seconds, the system will determine the abnormality, issue an alarm, and stop charging, thereby avoiding potential safety hazards.
[0060] In one feasible implementation, this application provides a charging pile, which is equipped with the energy metering chip inside. The charging pile implements the battery charging control method described above through the energy metering chip and the control program.
[0061] Charging stations are devices used to charge electric vehicles, electric bicycles, and other electric equipment. They typically include a charging interface, a power module, a control module, a metering module, and a display module. The power metering chip measures charging parameters such as voltage and current in real time, while the control module runs a control program to implement the charging control logic.
[0062] In one feasible implementation, this application provides a charging cabinet, which is equipped with the power metering chip inside. The charging cabinet implements the battery charging control method described above through the power metering chip and the control program.
[0063] A charging cabinet is a centralized charging device that typically contains multiple charging compartments, allowing multiple batteries to be charged simultaneously. Charging cabinets are widely used in electric bicycle battery swapping stations, battery rental stations, and other similar applications.
[0064] Each charging compartment in the charging cabinet is equipped with an independent charging circuit and energy metering chip, allowing for independent control of the charging process for each battery. The control module of the charging cabinet can centrally manage all charging compartments, enabling batch charging control.
[0065] In one feasible implementation, this application provides a charging platform, the charging platform including: a memory, a processor, and a battery charging control program stored in the memory and executable on the processor, the battery charging control program being configured to implement the steps of the battery charging control method as described above.
[0066] The charging platform can take the form of a standalone controller, an embedded system, or an industrial control computer. It can also include a communication interface for data interaction with host computers, cloud platforms, and mobile terminals, enabling functions such as remote monitoring, data statistics, and fault diagnosis.
[0067] For example, when parameter adjustments are required, the charging platform sends multiple full-charge stop parameters and multiple disconnect stop parameters to the charging pile for adjustment.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
