Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0020] Figure 1 is a flow chart of a battery charging and discharging management method provided in an embodiment of the present application; Figure 2 It is a functional module diagram of a battery charge and discharge management device provided in an embodiment of the present application; Figure 3 It is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application. DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] like Figure 1 FIG. 1 is a flow chart of a battery charge and discharge management method provided in an embodiment of the present application. The battery charge and discharge management method provided in an embodiment of the present application includes the following steps.

[0023] Step S11 , monitoring whether the target power source has power input and / or output.

[0024] A sensor is provided in the target interface of the target power source. When current transmission is detected at the target interface, the sensor generates a preset electrical signal and transmits it to the battery management system (BMS) circuit board, thereby causing a signal change in the BMS circuit board. The BMS circuit board determines whether there is power input and / or output of the target power source by detecting the signal change.

[0025] Step S12: when the target power source has power input and / or output, obtain the working status information and current power of the target power source in real time.

[0026] The working state information includes but is not limited to the battery temperature (hereinafter referred to as the working state information by the battery temperature). The BMS circuit board obtains the battery temperature of the target power source in real time through the integrated temperature sensor and the power source detection sensor.

[0027] When it is determined that the target power supply has power input and / or output, the target interface is used to implement a wired communication link with the target external device. This process involves identifying and parsing the charge and discharge protocol followed by the external device to determine the charging or discharging mode that the target power supply should adopt. Subsequently, based on the identified charge and discharge protocol, a protocol handshake process is executed between the target power supply and the external device, which is intended to establish a series of key parameters required during the charging or discharging process. These key parameters include, but are not limited to: the acceptable range of voltage and current, the basic power level, and the protection mechanism implemented to ensure the safety of the transmission process, such as safety measures to prevent excessive current (overcurrent protection) and excessive temperature (overtemperature protection).

[0028] Step S13: determining adjustment parameters according to the working status information.

[0029] It should be understood that the battery will generate heat during operation, which will be transferred to the surface of the battery and captured by the temperature sensor. The temperature state inside the battery directly reflects its workload, charging and discharging efficiency, and possible safety hazards. The performance of the battery (such as capacity, internal resistance, charging and discharging efficiency, etc.) is significantly affected by temperature. Too high or too low temperature may cause the battery performance to deteriorate and even cause safety problems. Therefore, by monitoring the battery temperature, the working state of the battery can be indirectly evaluated.

[0030] After the battery temperature is acquired, the adjustment parameters for adjusting the influence of different factors on power regulation are determined according to a preset mapping table between the battery temperature and the adjustment parameters.

[0031] Step S14: Calculate a power adjustment parameter value according to the adjustment parameter, the current electric power and a preset adjustment formula.

[0032] After obtaining the adjustment parameter and the current electric power, the BMS circuit board calculates the power adjustment parameter value by the following formula: ΔP=Kg(T).h(P) Wherein, ΔP is the power adjustment parameter value, K is the adjustment sensitivity, g(T) is the temperature adjustment parameter, and h(P) is the power adjustment parameter. The value of K is related to the battery temperature of the current target power source.

[0033] At the same time, the temperature adjustment parameter is calculated by the following formula: Wherein, T is the battery temperature of the target power source acquired in real time, T opt is the optimal operating temperature of the target power supply, T range is the operating temperature range of the target power supply.

[0034] And the power adjustment parameter is calculated by the following formula: Wherein, P is the current electric power of the target power source acquired in real time, P opt is the target power of the target power source, P range is the input and / or output range of the target power supply.

[0035] Step S15: adjusting the input and / or output of the target power source according to the power adjustment parameter value and the current electric power.

[0036] After obtaining the power regulation parameter value and the current electric power, the BMS circuit board calculates the regulated power using the following formula: P1 = P + ΔP; Wherein, P is the current electric power of the target power source acquired in real time, P1 is the adjusted power, and ΔP is the power adjustment parameter value. When ΔP is positive, it means that the power needs to be increased; when ΔP is negative, it means that the power needs to be reduced. If the target power source is charging and ΔP is positive, the charging power is increased; if ΔP is negative, the charging power is reduced or charging is stopped. If the target power source is discharging and ΔP is positive, the discharging power is increased (within the safe range allowed by the battery); if ΔP is negative, the discharging power is reduced or the discharging is limited.

[0037] In an optional embodiment, to prevent potential damage or failure caused by regulating power beyond the physical limitations or safety thresholds of the power supply, the method further includes: Determining whether the regulated power is within the input and / or output range of the target power supply; When the regulated power is not within the input and / or output range of the target power supply, an alarm is issued according to a preset alarm mode.

[0038] After obtaining the regulated power through P1=P+ΔP, it is necessary to determine whether the calculated regulated power P1 is within the input and / or output range allowed by the target power supply. This range is usually determined by the physical characteristics of the power supply, safety standards, and user needs. For example, for a lithium-ion battery, its charging power and discharging power have clear upper and lower limits.

[0039] When the adjusted power P1 is not within the allowed range, the system needs to alarm according to the preset alarm method. The alarm method may include but is not limited to: sound alarm, visual alarm (such as LED flashing), software interface prompt, sending alarm information to the remote monitoring system, etc. The purpose of the alarm is to notify the operator or system administrator in time so that they can take appropriate measures to solve the problem.

[0040] For example, a lithium-ion battery pack has a maximum charging power of 100W and a maximum discharging power of 200W. Currently, the battery pack is discharging at a power of 50W. According to the adjustment formula, ΔP=20W is obtained. Then the adjustment power obtained according to P1=P+ΔP is 70W. Since 70W is within the maximum discharge power of 200W allowed by the battery pack, the adjustment power P1 is within the allowable range and no alarm processing is required.

[0041] When the adjustment formula obtains ΔP=160W, the adjustment power obtained according to P1=P+ΔP is 210W. Since 210W exceeds the maximum discharge power allowed by the battery pack, an alarm process is required.

[0042] The present application is applied to the field of battery management technology. The present application uses a sensor to monitor in real time whether the target power supply has an electric energy input and / or output state. When the target power supply is monitored to have an electric energy input and / or output, data collection is started to obtain the working state information and current electric power value of the target power supply in real time. Based on the collected working state information, the adjustment parameters are determined, and the power adjustment parameter value is calculated using a preset adjustment formula to automatically adjust the input and / or output of the target power supply according to the power adjustment parameter value. The present application can ensure that the power supply operates in the optimal working range, reduce unnecessary energy consumption, and improve the adjustment efficiency of the target power supply through real-time monitoring and dynamic adjustment of the working state of the power supply.
