[0002] At present, with the rise of outdoor activities, the demand for outdoor electronic equipment and emergency backup power supplies is increasing. Outdoor power supplies have also become an indispensable equipment for current outdoor activities. However, if the outdoor power supply exceeds the maximum power of the product during use, it will cause accidents and pose safety risks. Therefore, it is necessary to further control the charging and discharging of outdoor power supplies.

[0003] The existing charging and discharging overload protection of outdoor power supplies is usually achieved by installing a safety valve or an external dedicated charging circuit to provide the outdoor power supply with a greater degree of overcharge protection. When the outdoor power supply reaches the safety threshold of the safety valve, the charging circuit is promptly blocked by the safety valve, so that the charging and discharging process of the outdoor power supply can be stopped in time, reducing the risk of explosion caused by further heating or overcharging of the outdoor power supply. However, the "one-size-fits-all" blocking method can easily bring a bad user experience. Therefore, there is room for further optimization and improvement of the charging and discharging overload protection method of the outdoor power supply. Summary of the invention

[0051] The present application is further described in detail below in conjunction with the accompanying drawings.

[0052] In one embodiment, if Figure 1 As shown, the present application discloses a charging and discharging overload protection management method based on an outdoor power supply, which specifically includes the following steps:

[0053] S10: Obtain the battery heating rate and battery internal pressure change of the outdoor power supply at different ambient temperatures, and comprehensively analyze the chemical correlation between the battery chemical reaction of the outdoor power supply and the ambient temperature change.

[0054] Specifically, taking the ambient temperature of the outdoor power supply as a variable, the outdoor power supply is tested by setting multiple groups of ambient temperature control groups, the outdoor power supply is placed in multiple groups of ambient temperature control groups for operation, and the battery heating rate and battery internal pressure changes of each ambient temperature control group are collected, so as to construct a chemical correlation between the battery heating rate and battery internal pressure changes caused by the battery chemical reaction, and the ambient temperature changes of different control groups.

[0055] S20: Analyze the critical overload parameters of the battery of the outdoor power supply at different ambient temperatures based on the battery heating rate and the change in the internal pressure of the battery.

[0056] Specifically, the critical overload parameter of the battery of the outdoor power supply at different ambient temperatures is expressed by formula (1), and formula (1) is as follows:

[0057]

[0058] Among them, E 临 Indicates the critical discharge voltage of the battery of the outdoor power supply, P 输 represents the output power of the outdoor power supply, δ represents the power factor used to represent the power supply discharge efficiency, ε 耗 It represents the outdoor power supply discharge loss coefficient, which is related to the number of charge and discharge times of the outdoor power supply. C represents the ambient temperature. I 1 ,I 2 ,…,I n They respectively represent the charge and discharge current of the nth connected load of the outdoor power supply, and N represents the number of battery groups of the outdoor power supply.

[0059] S30: According to the chemical association relationship and the critical overload parameter, a power management model of the battery charging and discharging parameters of the outdoor power supply under different ambient temperature changes is constructed.

[0060] Specifically, the chemical correlation relationship and the corresponding critical overload parameters are used, and the chemical correlation relationship under different ambient temperatures is analyzed with the critical overload parameters as the threshold, so as to construct a power management model of the battery charging and discharging parameters of the outdoor power supply under different ambient temperature changes, which is used to control the outdoor power supply to operate within a safe range that does not exceed the critical overload parameters and to make timely adjustments when an abnormal situation occurs that causes the power supply to exceed the critical overload parameters.

[0061] S40: Obtain access load data of the outdoor power supply, input the access load data into the power management model, analyze the optimal charge and discharge parameters of each access load, and obtain the charge and discharge management data of the outdoor power supply.

[0062] Specifically, Figure 2 As shown, step S40 includes:

[0063] S401: Acquire the charge and discharge state of each connected load of the outdoor power supply, plan the charge and discharge frequency and single charge and discharge power of the connected loads under the same charge and discharge state, and obtain initial charge and discharge parameters of the connected loads.

[0064] Specifically, the charge and discharge status of each connected load of the outdoor power supply is obtained, including charging, discharging, saturated charge or saturated discharge, etc., and the charge and discharge frequency and single charge and discharge power are planned for the connected loads in the same charge and discharge status as in the charging status. For example, when the charge and discharge frequency exceeds the discharge frequency of the outdoor power supply energy storage battery, the charge and discharge frequency of the connected load currently in the charging status is adjusted to make the comprehensive charging frequency within the range of the normal discharge frequency of the energy storage battery, and the single charge and discharge power of some high-power connected loads is adjusted, and the high-power load is charged during the low-peak discharge period of the energy storage battery, so as to obtain the initial charge and discharge parameters of the connected loads.

[0065] S402: In the process of charging and discharging according to the initial charging and discharging parameters, the charging and discharging temperature rise rate of the outdoor power source and the battery energy storage loss rate are obtained.

[0066] Specifically, when the outdoor power supply charges and discharges all connected loads according to the initial charge and discharge parameters, the real-time charge and discharge temperature and power loss data of the outdoor power supply per unit time are collected, so as to calculate the charge and discharge temperature rise rate of the outdoor battery and the battery energy storage loss rate.

[0067] S403: Coordinated parameter adjustment is performed on the initial charge and discharge parameters of all connected loads, and when the charge and discharge temperature rise rate and the battery energy storage loss rate reach a balanced state, the optimal charge and discharge parameters of all connected loads are obtained.

[0068] Specifically, the initial charging and discharging parameters of all connected loads are coordinated and adjusted. High-power connected loads are operated during the peak charging and discharging period of the outdoor power supply, and low-power connected loads are operated during the low-peak charging and discharging period of the outdoor power supply, until the charging and discharging heating rate of the outdoor power supply and the battery energy storage loss rate reach a balanced state, that is, a uniformly changing state. The charging and discharging parameters of the connected loads that reach the balanced state are taken as the optimal charging and discharging parameters.

[0069] In this embodiment, Figure 3 As shown, step S403 also includes:

[0070] S4031: When the load connected to the outdoor power source exceeds the battery rated critical value, charge and discharge priority planning is performed on all connected loads according to the connected load type to obtain the charge and discharge priority related to the connected load type.

[0071] Specifically, when the connected load of the outdoor power supply exceeds the rated critical value of the battery, the power management model is used to adjust and control in a timely manner, and combined with the load types of all currently connected loads, the charging and discharging priority of all connected loads is planned. For example, charging the power supply takes precedence over discharging the power supply, and loads inserted with two-hole or three-hole plugs take precedence over those connected through the USB interface. It can be set according to actual needs to obtain the charging and discharging priority related to the connected load type.

[0072] S4032: According to the charging and discharging priority, polling charging and discharging processing is performed on all connected loads, and the battery of the outdoor power supply is controlled to perform segmented charging and discharging of each connected load, so as to obtain segmented charging and discharging parameters of the outdoor power supply.

[0073] Specifically, according to the charging and discharging priority, all connected loads are polled for charging and discharging, thereby reducing the charging and discharging demand of the outdoor power supply, and the battery of the outdoor power supply is controlled to perform segmented charging and discharging processing on each connected load, and loads with high priority are charged first. When the connected load with high priority is in a charging saturation or charging dormant state, the connected load with the second priority is charged, and so on, thereby obtaining the segmented charging and discharging parameters of the outdoor power supply.

[0074] S404: Acquire the power usage status of each connected load, associate the optimal charging and discharging parameters with the power usage status of the corresponding connected load, and obtain the charging and discharging management data of the outdoor power supply.

[0075] Specifically, in each round of charging and discharging of the outdoor power supply, the power usage status of each connected load is obtained, including whether it is in use, power saturated, or load dormant. Taking the connected load as the association point, the optimal charging and discharging parameters are data-associated with the power usage status of the corresponding connected load to obtain the charging and discharging management data of the outdoor power supply.

[0076] In this embodiment, Figure 4 As shown, step S40 also includes:

[0077] S405: When the load connected to the outdoor power source changes, the load mutation data of the outdoor power source is obtained, and the instantaneous change of the battery when the load mutation occurs is analyzed to obtain the battery transient change data.

[0078] Specifically, when the connected load of the outdoor power supply changes, such as abnormal charging and discharging current or voltage caused by a connected load failure, the load mutation data is obtained based on the charging and discharging feedback of the outdoor power supply to the abnormal connected load, and the instantaneous changes of the battery when the load mutation occurs are analyzed according to the protective gear on the edge of the load diagram, including battery temperature changes, battery internal pressure changes, and battery energy storage changes, thereby obtaining the battery transient change data.

[0079] S406: According to the battery transient change data, the charge and discharge power and charge and discharge frequency of all connected loads that are performing charge and discharge operations are coordinated to obtain adjusted dynamic charge and discharge parameters.

[0080] Specifically, according to the battery transient change data, the charging and discharging power and charging and discharging frequency of all connected loads that are performing charging and discharging operations are coordinated and adjusted. For example, after eliminating abnormal connected loads, the charging and discharging power of all running connected loads is recalculated, and the charging and discharging frequency of each connected load is replanned to obtain adjusted dynamic charging and discharging parameters.

[0081] S407: According to the dynamic charge and discharge parameters, the changing connected load is subjected to electric energy redistribution processing to obtain charge and discharge mutation control data when a sudden load change occurs in the outdoor power supply.

[0082] Specifically, according to the dynamic charging and discharging parameters, the electric energy is redistributed for the connected loads with changes, that is, after eliminating the abnormal connected loads, the battery electric energy is distributed to other circuits with the same load interface, so as to obtain the charging and discharging mutation control data when the outdoor power supply has a sudden load change.

[0083] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
