Description

Technical Field

[0001] This invention relates to the field of outdoor emergency power supplies, specifically to a charging and discharging control system and method adapted to portable outdoor emergency power supplies. Background Technology

[0002] Emergency power supplies are typically used in outdoor activities where it is far from mains power or inconvenient to run power lines, such as camping and outdoor adventure. Emergency power supplies also play an important role in power outages and disaster relief. Existing emergency power supplies generally contain rechargeable batteries. By storing a large amount of power in the batteries, the emergency power supply can output the stored power when it is carried to the place of use.

[0003] Currently, with the development of outdoor emergency power supply technology, the combination of intelligent control systems and outdoor emergency power supplies can provide more durable emergency power output and a longer lifespan with more charge and discharge cycles. However, existing outdoor emergency power supply charge and discharge control systems focus more on simple temperature control during charging and discharging, thus ignoring the correlation control between the battery's input and output parameters and battery capacity. They also cannot intervene in the charge and discharge control strategy based on the battery's charge level. As a result, the multi-parameter correlation of outdoor emergency power supplies is insufficient during use, making it impossible to provide more scientific control for outdoor emergency power supplies.

[0004] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention

[0005] This invention comprehensively collects data on the battery charge, operating temperature during charging and discharging, and input / output parameters of the outdoor emergency power supply. This enables control of the battery charging and discharging process, ensuring that the outdoor emergency power supply can automatically and adaptively adjust its input / output parameters under different charge levels and operating temperatures. This solves the problem that outdoor emergency power supplies cannot comprehensively intervene and control charging and discharging based on multiple aspects of the battery during use. Therefore, this invention proposes a charging and discharging control system and method adapted to portable outdoor emergency power supplies.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A charging and discharging control system adapted to portable outdoor emergency power supplies includes a parameter monitoring module, an operation monitoring module, and a charging and discharging control unit. The parameter monitoring module is used to acquire parameter information of the outdoor emergency power supply, obtain the capacity and temperature management status of the outdoor emergency power supply based on the acquired parameter information, and send the capacity and temperature management status to the charging and discharging control unit.

[0008] The operation monitoring module is used to collect operating parameters during the operation of the emergency power supply, and obtain input management status and output management status based on the collection results. The operation monitoring module then sends the input management status and output management status to the charging and discharging control unit.

[0009] After acquiring the output management status, input management status, capacity status, and temperature management status, the charge and discharge control unit performs comprehensive analysis of the acquired information to achieve charge and discharge control of the emergency power supply. The charge and discharge control methods include charge and discharge rate and charge and discharge saturation.

[0010] In a preferred embodiment of the present invention, the parameter monitoring module includes a capacity management unit and a temperature management unit, wherein the capacity management unit is used to monitor the battery capacity of the outdoor emergency power supply in real time, thereby obtaining the current power of the outdoor emergency battery and recording the current power as the capacity status.

[0011] The temperature management unit collects the current temperature of the outdoor emergency power supply and records the collected temperature as the current temperature. Each time the current temperature is acquired, the temperature management unit calculates the difference between the current temperature and the previous temperature to obtain the temperature change difference, and records the temperature change value and the current temperature as the temperature management status.

[0012] In a preferred embodiment of the present invention, the operation monitoring module includes an output monitoring unit and an input monitoring unit;

[0013] The output monitoring unit can collect the current output parameters of the outdoor emergency power supply during operation, obtain real-time output parameters, and record the real-time output parameters as output management status. The real-time output parameters include the output current and output voltage. The input monitoring unit collects the current input parameters during the charging process of the outdoor emergency power supply, obtains real-time input parameters, and records the real-time input parameters as input management status. The real-time input parameters include the input current value and voltage value.

[0014] In a preferred embodiment of the present invention, the charging and discharging control unit obtains real-time output parameters and real-time input parameters through the operation monitoring module, and obtains the current power and temperature management status through the parameter monitoring module;

[0015] The charging and discharging control unit acquires the current power level and compares it with a set low power threshold. Based on the comparison result, it generates a low power signal and an intermediate power signal.

[0016] The charging and discharging control unit compares the current power level with a set high power threshold, and generates a high power signal and an intermediate power signal based on the comparison result.

[0017] In a preferred embodiment of the present invention, the charge and discharge control unit determines the current charge and discharge state. If it is in the discharge state and a low power signal is generated, a charging reminder is generated, and the output parameters are compared with the set low output threshold. Based on the comparison result, an output too high signal or an output normal signal is generated, and the output parameters are reduced after the output too high signal is generated.

[0018] If it is determined that the outdoor emergency power supply is currently in a discharging state and generates a high power signal, the temperature change difference is compared with the set difference threshold to obtain the heating rate ratio.

[0019] The current temperature of the outdoor emergency power supply is compared with the set temperature threshold to obtain the high temperature ratio. The charging and discharging control unit performs formula analysis based on the high temperature ratio and the heating rate ratio to obtain the temperature over-limit value. The maximum value of the output parameter is controlled by the reciprocal of the temperature over-limit value.

[0020] In a preferred embodiment of the present invention, after determining that the outdoor emergency power supply is currently in a charging state, the charging and discharging control unit, if a low power signal is generated at the same time, compares the current temperature of the outdoor emergency power supply with a set high temperature threshold. If the current temperature is not greater than the high temperature threshold, a fast charging signal is generated; if the current temperature is greater than the high temperature threshold, a normal charging signal is generated.

[0021] If a high power signal is generated at the same time, the current temperature of the outdoor emergency power supply is compared with the set low temperature threshold, and a fast charging signal and a normal charging signal are generated based on the comparison result.

[0022] The high temperature threshold is greater than the low temperature threshold.

[0023] In a preferred embodiment of the present invention, the charging and discharging control unit calculates the capacity change of the outdoor emergency power supply during each charging and discharging process, and records the ratio of the average value of the capacity change during the discharge of the outdoor emergency power supply to the maximum capacity as the discharge saturation, and records the ratio of the average value of the capacity change during the charging of the outdoor emergency power supply to the maximum capacity as the charging saturation.

[0024] The charge / discharge control unit sends the discharge saturation and charge saturation to the cloud, and records the discharge saturation and charge saturation through the cloud.

[0025] A charging and discharging control method adapted for portable outdoor emergency power supplies includes the following steps:

[0026] Step 1: Acquire input and output parameters;

[0027] Step 2: Collect runtime parameters;

[0028] Step 3: Determine the charging / discharging state;

[0029] Step 4: Charge / discharge rate control;

[0030] Step 5: Statistical analysis of charge and discharge saturation.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. This invention comprehensively collects data on the battery charge, operating temperature during charging and discharging, and input / output parameters of the outdoor emergency power supply to control the battery charging and discharging process. This ensures that the outdoor emergency power supply can automatically and adaptively adjust its input / output parameters under different charge levels and operating temperatures, thus guaranteeing the longest possible power supply time. This prioritizes providing necessary power for essential operations and allows for the fastest possible partial charging during charging. This ensures that the outdoor emergency power supply maintains a high charge level and extends its service life.

[0033] 2. In this invention, during the charging and discharging control of the outdoor emergency power supply, the charging and discharging status of the outdoor emergency power supply is statistically analyzed, and the charging and discharging saturation of the outdoor emergency power supply is analyzed based on the statistical results, thereby providing a data-driven quantitative expression of the service life and usage of the outdoor emergency power supply. Attached Figure Description

[0034] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0035] Figure 1 This is a system block diagram of the present invention;

[0036] Figure 2 This is a system flowchart of the present invention. Detailed Implementation

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Please see Figure 1 - Figure 2As shown, the charging and discharging control system adapted to portable outdoor emergency power supplies includes a parameter monitoring module, an operation monitoring module, and a charging and discharging control unit. The parameter monitoring module includes a capacity management unit and a temperature management unit. The parameter monitoring module is used to acquire parameter information of the outdoor emergency power supply and obtain the capacity and temperature management status of the outdoor emergency power supply based on the acquired parameter information. The capacity management unit is used to monitor the battery capacity of the outdoor emergency power supply in real time and record the current power level as the capacity status.

[0040] The temperature management unit collects the current temperature of the outdoor emergency power supply and records the collected temperature as the current temperature. Each time the current temperature is acquired, the temperature management unit calculates the difference between the current temperature and the previous temperature to obtain the temperature change difference, and records the temperature change value and the current temperature as the temperature management status.

[0041] The parameter monitoring module sends capacity and temperature management information to the charge / discharge control unit.

[0042] The operation monitoring module includes an output monitoring unit and an input monitoring unit. The output monitoring unit can collect the current output parameters of the outdoor emergency power supply during operation, obtain real-time output parameters, and record the real-time output parameters as output management status. The real-time output parameters include the output current and output voltage. The input monitoring unit collects the current input parameters during the charging process of the outdoor emergency power supply, obtains real-time input parameters, and records the real-time input parameters as input management status. The real-time input parameters include the input current value and voltage value.

[0043] The operation monitoring module sends the input and output management information to the charge and discharge control unit.

[0044] Example 2:

[0045] Please see Figure 1 - Figure 2 As shown, the charging and discharging control unit obtains real-time output and input parameters through the operation monitoring module, and obtains the current power and temperature management status through the parameter monitoring module;

[0046] The charging and discharging control unit obtains the current power level and compares it with the set low power threshold. If the current power level is lower than the set low power threshold, a low power signal is generated. If the current power level is greater than or equal to the set low power threshold, an intermediate power signal is generated.

[0047] The charging and discharging control unit compares the current battery level with the set high battery level threshold. If the current battery level is greater than the set high battery level threshold, a high battery level signal is generated. If the current battery level is less than or equal to the set high battery level threshold, an intermediate battery level signal is generated.

[0048] The charge / discharge control unit determines the current charge / discharge state:

[0049] If the device is in a discharging state and a low battery signal is generated, a charging reminder is generated, and the output parameters are compared with the set low output threshold. If the output parameters are greater than the set low output threshold, an output overload signal is generated. If the output parameters are less than or equal to the set low output threshold, a normal output signal is generated. After the output overload signal is generated, the output parameters are reduced until a normal output signal is generated.

[0050] If it is determined that the outdoor emergency power supply is currently in a discharging state and generates a high power signal, the temperature change difference is compared with the set difference threshold to obtain the heating rate ratio.

[0051] The current temperature of the outdoor emergency power supply is compared with the set temperature threshold to obtain the high temperature ratio. The charging and discharging control unit then performs a formula analysis based on the high temperature ratio and the heating rate ratio to obtain the temperature exceedance value TC. Where TQ is the high temperature ratio, TS is the heating rate ratio, θ is the set weighting coefficient, and the maximum value of the output parameter is controlled by the reciprocal of the temperature over-limit value, thus obtaining the maximum value Pmax of the output parameter. P0 is the preset initial maximum value of the output parameters, and q is the set weight coefficient;

[0052] After determining that the outdoor emergency power supply is currently charging, if a low power signal is generated at the same time, the charging and discharging control unit will compare the current temperature of the outdoor emergency power supply with the set high temperature threshold. If the current temperature is not greater than the high temperature threshold, a fast charging signal will be generated; if the current temperature is greater than the high temperature threshold, a normal charging signal will be generated.

[0053] If a high-power signal is generated simultaneously, the current temperature of the outdoor emergency power supply is compared with the set low-temperature threshold. If the current temperature is greater than the set low-temperature threshold, a normal charging signal is generated. If the current temperature is less than or equal to the set low-temperature threshold, a fast charging signal is generated. The high-temperature threshold is greater than the low-temperature threshold. This increases the charging speed when the outdoor emergency power supply has a low power level and decreases the charging speed when the outdoor emergency power supply has a high power level, thereby extending the charging and discharging lifespan of the outdoor emergency power supply.

[0054] Example 3:

[0055] Please see Figure 1 - Figure 2 As shown, the charging and discharging control unit calculates the capacity change of the outdoor emergency power supply during each charging and discharging process. The ratio of the average capacity change during the discharge of the outdoor emergency power supply to the maximum capacity is recorded as the discharge saturation. The ratio of the average capacity change during the charging of the outdoor emergency power supply to the maximum capacity is recorded as the charging saturation.

[0056] The charge and discharge control unit sends the discharge saturation and charge saturation to the cloud, and records the discharge saturation and charge saturation through the cloud. This provides managers with information on the completeness of charge and discharge of the outdoor emergency power supply during each operation. Based on the completeness of charge and discharge of the outdoor emergency power supply, the lifespan of the outdoor emergency power supply can be more accurately estimated, thereby reasonably scheduling maintenance, repair, and replacement / disposal times.

[0057] Example 4:

[0058] Please see Figure 1 - Figure 2 As shown, the charging and discharging control method adapted to portable outdoor emergency power supplies includes the following steps:

[0059] Step 1: Collect input and output parameters through the parameter monitoring module and send the collected parameters to the charge and discharge control unit;

[0060] Step 2: The operating monitoring module collects operating parameters and sends the collected capacity and temperature management information to the charge / discharge control unit;

[0061] Step 3: The charging and discharging control unit judges the current status of the outdoor emergency power supply and confirms its charging and discharging status.

[0062] Step 4: Control the charging and discharging rate based on input and output parameters, capacity, and temperature management to improve the usage time and charging speed of the outdoor emergency power supply;

[0063] Step 5: Calculate the charge and discharge saturation levels to estimate the maintenance interval and service life of the outdoor emergency power supply.
