[0002] Emergency power supplies are usually used in outdoor activities far away from the mains or where it is inconvenient to connect to power lines, such as camping in the wild, outdoor adventures, etc. At the same time, emergency power supplies can also play an important role in power outage emergencies and disaster relief. Emergency power supplies in the prior art are generally provided with rechargeable batteries. By storing a large amount of power in the battery in the emergency power supply, when the emergency power supply is carried to the place of use, the emergency power supply will output the electric energy stored in the battery for use;

[0003] At present, with the development of outdoor emergency power supply technology, the combination of intelligent control system and outdoor emergency power supply can provide outdoor emergency power supply with more durable emergency power output and longer service life of charging and discharging times. However, the existing outdoor emergency power supply charging and discharging control system focuses more on simple temperature control during charging and discharging, thus ignoring the correlation control between the input and output parameters of the battery and the battery capacity, and cannot intervene in the charging and discharging control strategy according to the battery power, so that the outdoor emergency power supply has insufficient correlation between multiple parameters during use, and cannot provide more scientific control for the outdoor emergency power supply;

[0004] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0037] The technical scheme of the present invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] See also Figure 1 - Figure 2As shown, a charging and discharging control system adapted for a portable outdoor emergency power supply includes a parameter supervision module, an operation supervision module and a charging and discharging control unit. The parameter supervision module includes a capacity management unit and a temperature management unit. The parameter supervision module is used to obtain parameter information of the outdoor emergency power supply, and obtain the capacity and temperature management of the outdoor emergency power supply according to the obtained 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 as the capacity condition;

[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 temperature is obtained, the temperature management unit calculates the difference between the current temperature and the temperature obtained last time to obtain the temperature change difference, and records the temperature change value and the current temperature as the temperature management situation;

[0041] The parameter monitoring module sends the capacity and temperature management status to the charging and discharging control unit.

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

[0043] The operation supervision module sends the input management status and output management status to the charging and discharging control unit.

[0044] Embodiment 2:

[0045] See also Figure 1 - Figure 2 As shown, the charge and discharge control unit obtains real-time output parameters and real-time input parameters by running the supervision module, and obtains the current power and temperature management status through the parameter supervision module;

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

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

[0048] The charge and discharge control unit determines the current charge and discharge status:

[0049] If it is in the discharging state and a low power signal is generated, a charging reminder is generated, and the output parameter is compared with the set low output threshold. If the output parameter is greater than the set low output threshold, an output over-high signal is generated. If the output parameter is less than or equal to the set low output threshold, an output normal signal is generated, and after the output over-high signal is generated, the output parameter is reduced until the output normal signal is generated;

[0050] If it is determined that the outdoor emergency power supply is currently in a discharging state and a high power signal is generated, the temperature change difference is compared with the set difference threshold to obtain the temperature rise 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 charge and discharge control unit performs formula analysis based on the high temperature ratio and the heating rate ratio to obtain the temperature over-limit value TC. , where TQ is the high temperature ratio, TS is the heating rate ratio, θ is the set weight coefficient, and the maximum value of the output parameter is controlled by the inverse of the temperature limit value to obtain the maximum value of the output parameter Pmax, , P0 is the preset initial maximum value of the output parameter, and q is the set weight coefficient;

[0052] After the charging and discharging control unit determines that the outdoor emergency power supply is currently in a charging state, if a low power signal is generated at the same time, the current temperature of the outdoor emergency power supply is compared with the 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;

[0053] 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. 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, wherein the high temperature threshold is greater than the low temperature threshold. This increases the charging speed when the outdoor emergency power supply is low in power, and reduces the charging speed when the outdoor emergency power supply is high in power, so as to extend the charging and discharging service life of the outdoor emergency power supply.

[0054] Embodiment three:

[0055] See also Figure 1 - Figure 2 As shown, the charge-discharge control unit calculates the capacity change amplitude of the outdoor emergency power supply during each charge-discharge process, and records the ratio of the average value of the capacity change amplitude when the outdoor emergency power supply is discharged to the maximum capacity as the discharge saturation, and records the ratio of the average value of the capacity change amplitude when the outdoor emergency power supply is charged to the maximum capacity 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, thereby providing managers with the thoroughness of charge and discharge of the outdoor emergency power supply each time it works. The service life of the outdoor emergency power supply can be more accurately estimated based on the thoroughness of charge and discharge of the outdoor emergency power supply, thereby reasonably arranging the time points for maintenance, inspection, replacement and scrapping.

[0057] Embodiment 4:

[0058] See also Figure 1 - Figure 2 As shown, a charging and discharging control method adapted for a portable outdoor emergency power supply comprises the following steps:

[0061] Step 3: The charging and discharging control unit determines the current state of the outdoor emergency power supply and confirms the charging and discharging state of the outdoor emergency power supply;

[0062] Step 4: Control the charge and discharge rate according to input and output parameters, capacity and temperature management to improve the use time and charging speed of the outdoor emergency power supply;
