Figure 1 As shown, the system includes a device housing, a data acquisition module, a data analysis module and a charge and discharge control module.

[0059] Further, according to another aspect of the present application, a battery charge and discharge control method is also disclosed. For ease of understanding, the specific process of the embodiment of the present invention is described below. Specifically, Figure 2 This is a flow chart of the battery charging and discharging control method of the present application, and the steps include:

[0060] S100: The data acquisition module acquires parameter data of the target battery in the current state.

[0061] Specifically, the data acquisition module can collect parameter data of the target battery in real time. Among them, the current state can be a charging state or a discharging state, and the target battery is the battery currently undergoing data acquisition. In some examples, the parameter data may include but is not limited to charging current, charging voltage, discharging current, discharging voltage, charging temperature, discharging temperature, etc. In general, these data will be collected at a certain frequency (for example, every second) to facilitate understanding of the performance changes of the target battery throughout the charging process or discharging process.

[0062] S102: The data acquisition module sends the parameter data to the data analysis module.

[0063] Specifically, the data acquisition module is electrically connected to the data analysis module, and the data acquisition module and the data analysis module can communicate, for example, wireless communication or wired communication, so that the data acquisition module can send the collected parameter data of the target battery to the data analysis module.

[0064] S104: After receiving the parameter data, the data analysis module performs data analysis on the parameter data to obtain performance indicators of the target battery.

[0065] Specifically, after receiving the parameter data sent by the data acquisition module, the data analysis module analyzes the parameter data, for example, it can determine the charging resistance based on the charging current and charging voltage, and further analyze whether the charging resistance is stable, thereby analyzing and obtaining the health status of the target battery as a performance indicator. For example, when the charging resistance is unstable, it means that the internal resistance of the target battery is too large or too small, and it is considered that the health status of the target battery is poor.

[0066] S106: The data analysis module sends the performance index to the charge and discharge control module.

[0067] Specifically, the data analysis module sends the performance indicators of the target battery obtained through analysis, such as good health status, poor health status, etc., to the charge and discharge control module.

[0068] S108. The charge and discharge control module receives the performance index, and determines a control strategy for the target battery according to the performance index and the current state.

[0069] Specifically, after receiving the performance indicators of the target battery sent by the data analysis module, the charge and discharge control module can first call up the control strategy table, wherein the control strategy table includes the correspondence between the performance indicators and the control strategies. After receiving the performance indicators, the charge and discharge control module can find out the control strategy corresponding to the received performance indicators from the control strategy table, and determine the control strategy of the target battery.

[0070] S110 , the charge and discharge control module controls the target battery according to the control strategy.

[0071] Specifically, the charge and discharge control module controls the target battery based on the determined control strategy, thereby achieving control of charging or discharging of the target battery.

[0072] Furthermore, Figure 3 Another flow chart of the battery charge and discharge control method of the present application is provided. The flow chart is an exemplary description when the current state is the charging state and the parameter data includes the charging current and the charging voltage. Figure 3 The steps include:

[0073] S200: The data acquisition module acquires parameter data of the target battery in the current state.

[0074] S202: The data acquisition module sends the parameter data to the data analysis module.

[0075] Specifically, the specific description of steps S200-S202 can refer to the description of the above steps S100-S102, which will not be repeated here.

[0076] S204, the data acquisition module collects the target battery at t 1 The first charging current and the first charging voltage at the moment.

[0077] S206: The data acquisition module collects the target battery at t 2 The second charging current and the second charging voltage at the moment.

[0078] S208. The data acquisition module sends the first charging current, the first charging voltage, the second charging current and the second charging voltage to the data analysis module.

[0079] Specifically, 2 The time can be the current time, t 1 The time may be a time before the current time. The interval between time t1 and time t2 may be 3s, 5s, 7s, etc., or other time intervals, which may be preset based on actual needs. After collecting the first charging current, the first charging voltage, the second charging current, and the second charging voltage, the data acquisition module sends them to the data analysis module.

[0080] S210. The data analysis module determines a current variation trend based on the first charging current and the second charging current.

[0081] Specifically, the data analysis module can analyze the change in value from the first charging current to the second charging current of the target battery. For example, assuming that the normal charging current of the target battery is between 1.0A and 1.5A, during normal charging, it is expected to see the current change smoothly within this range. If the first charging current is 1.2A, and it suddenly drops to 0.8A of the second charging current without obvious load changes, in this case, the analysis determines that the current change trend is too fast, which may indicate a problem with the battery. For example, the battery may be aged, or the internal resistance of the battery may increase.

[0082] S212: The data analysis module determines a voltage variation trend based on the first charging voltage and the second charging voltage.

[0083] Specifically, the data analysis module can analyze the change in value from the first charging voltage to the second charging voltage of the target battery, for example, assuming that the normal charging voltage of the target battery is between 4.2V and 4.5V. During normal charging, it is expected to see the voltage change smoothly within this range. If the first charging voltage is 4.2V and suddenly rises to 4.8V during charging, in this case, the analysis determines that the voltage change trend is rising too fast and the charging voltage is too high. Excessive voltage may cause the battery to overheat and may even cause safety problems.

[0084] It is understandable that the above-mentioned change in charging current or charging voltage is only an exemplary description. In other feasible schemes, the charging current may suddenly rise, and the charging voltage may suddenly drop. The specific change trend is based on the analysis of specific circumstances and is not exhaustively listed here.

[0085] S214: When the current variation trend does not satisfy the preset current variation trend and / or the voltage variation trend does not satisfy the preset voltage variation trend, the data analysis module determines that the health status of the target battery is abnormal.

[0086] Specifically, the preset current change trend can be a smooth change within the normal charging current range as in the above example, and the voltage change trend can be a smooth change within the normal charging voltage range as in the above example. Based on the above example, it can be seen that the current change trend does not satisfy the preset current change trend, and the voltage change trend does not satisfy the preset voltage change trend. At this time, the data analysis module analyzes and determines that the health status of the target battery is abnormal.

[0087] It can be understood that in step S214, when any one of the current change trend and the voltage change trend does not meet the preset change trend, it is analyzed and determined that the health status of the target battery is abnormal.

[0088] S216. The data analysis module sends the performance index to the charge and discharge control module.

[0089] Specifically, in this application embodiment, the data analysis module sends the performance indicator of abnormal health status to the charge and discharge control module.

[0090] S218. The charge and discharge control module receives the performance index, and determines a control strategy for the target battery according to the performance index and the current state.

[0091] Specifically, in this application embodiment, when the performance indicator is in an abnormal health state, the control strategy may be to stop charging.

[0092] S220. The charge and discharge control module controls the target battery according to the control strategy.

[0093] Specifically, in the embodiment of the application, the charge and discharge control module controls the target battery to stop charging.

[0094] Specifically, the present invention of the application embodiment can timely detect abnormal conditions of the battery by analyzing the battery parameter data, and then immediately adjust the charge and discharge strategy through the control module, thereby protecting the safety of the battery and extending the battery life. Furthermore, the embodiment of the present invention can analyze the charging or discharging trend of the battery in real time, and analyze the performance indicators of the battery in real time, thereby monitoring the health status of the battery, being able to timely detect and deal with battery problems, improve the safety of battery use, and extend the battery life; further, users can learn the real-time health status of the battery through this system, thereby better managing their equipment and improving user experience.

[0095] Furthermore, Figure 4 Another flowchart of the battery charge and discharge control method of the present application is another exemplary description when the current state is the charging state and the parameter data includes the charging current and the charging voltage. Figure 4 , the steps include:

[0096] S300. The data analysis module obtains an average charging current and an average charging voltage of a target battery in a target charging time period.

[0097] Specifically, before obtaining the average charging current, multiple charging currents can be collected at intervals within the target charging time period, and then the average value of the multiple charging currents can be obtained. Similarly, before obtaining the average charging voltage, multiple charging voltages can be collected at intervals within the target charging time period, and then the average value of the multiple charging voltages can be obtained. It can be understood that the target charging time period can be 1min, 2min, 4min, etc. or other time periods, and the interval time can be 2s, 4s, 5s, 7s, etc. or other time intervals, which can be preset. This is not exhaustive.

[0098] S302: The data analysis module analyzes the effective charging efficiency of the target battery based on the average charging current and the average charging voltage.

[0099] In one example, the effective charging efficiency can be determined based on the following formula:

[0100] P 1 =I 1 V 1 ,

[0101] Among them, P 1 is the effective charging efficiency, I 1 is the average charging current, V 1 is the average charging voltage.

[0102] S304. The charge and discharge control module receives the effective charging efficiency.

[0103] S306. The charge and discharge control module obtains a target charging efficiency.

[0104] Specifically, after analyzing the effective charging efficiency of the target battery, the data analysis module will send the effective charging efficiency to the charge and discharge control module. After receiving the effective charging efficiency, the charge and discharge control module will retrieve the target charging efficiency, wherein the target charging efficiency is used to characterize the required charging efficiency of the target battery, and the target charging efficiency is pre-set.

[0105] S308. When the effective charging efficiency meets the target charging efficiency, it is determined that the performance indicator of the effective charging efficiency of the target battery is normal, and the charge and discharge control module determines a control strategy to control the target battery to continue charging with the current charging current.

[0106] S310: When the effective charging efficiency does not meet the target charging efficiency, it is determined that the performance indicator of the effective charging efficiency of the target battery is abnormal, and the charge and discharge control module determines the control strategy to increase the charging current of the target battery.

[0107] Furthermore, Figure 5Another flow chart of the battery charge and discharge control method of the present application, when the current state is the discharge state, the parameter data includes an exemplary description of the discharge current and the discharge voltage, see Figure 5 , the steps include:

[0108] S400: The data analysis module obtains an average discharge current and an average discharge voltage of a target battery within a target discharge time period.

[0109] Specifically, before obtaining the average discharge current, multiple discharge currents can be collected at intervals within the target discharge time period, and then the average value of the multiple discharge currents can be obtained. Similarly, before obtaining the average discharge voltage, multiple discharge voltages can be collected at intervals within the target discharge time period, and then the average value of the multiple discharge voltages can be obtained. It can be understood that the target discharge time period can be 1min, 2min, 4min, etc. or other time periods, and the interval time can be 2s, 4s, 5s, 7s, etc. or other time intervals, which can be preset. This is not exhaustive.

[0110] S402: The data analysis module determines the effective discharge efficiency of the target battery based on the average discharge current and the average discharge voltage.

[0111] In one example, the effective discharge efficiency is determined based on the following formula:

[0112] P 2 =I 2 V 2 ,

[0113] Among them, P 2 is the effective discharge efficiency, I 2 is the average discharge current, V 2 is the average discharge voltage.

[0114] S404: The charge and discharge control module receives the effective discharge efficiency.

[0115] S406: The charge and discharge control module obtains a target discharge efficiency.

[0116] Specifically, after analyzing the effective discharge efficiency of the target battery, the data analysis module sends the effective discharge efficiency to the charge and discharge control module. After receiving the effective discharge efficiency, the charge and discharge control module retrieves the target discharge efficiency, wherein the target discharge efficiency is used to characterize the required discharge efficiency of the target battery, and the target discharge efficiency is pre-set.

[0117] S408. When the effective discharge efficiency meets the target discharge efficiency, it is determined that the performance indicator of the effective discharge efficiency of the target battery is normal, and the charge and discharge control module determines a control strategy to control the target battery to continue to discharge at the current discharge current.

[0118] S410: When the effective discharge efficiency does not meet the target discharge efficiency, it is determined that the performance indicator of the effective discharge efficiency of the target battery is abnormal, and the charge and discharge control module determines a control strategy of reducing the discharge current of the target battery or stopping discharge.

[0119] Furthermore, Figure 6 Another flow chart of the battery charge and discharge control method of the present application, when the current state is the discharge state, the parameter data includes another exemplary description of the discharge current and the discharge voltage, see Figure 6 , the steps include:

[0120] S500, the data acquisition module collects the target battery at t 1 The first discharge current and the first discharge voltage at the moment.

[0121] S502: The data acquisition module collects data of the target battery at t 2 The second discharge current and the second discharge voltage at the moment.

[0122] S504: The data acquisition module sends the first discharge current, the first discharge voltage, the second discharge current and the second discharge voltage to the data analysis module.

[0123] Specifically, 2 The time can be the current time, t 1 The time may be a time before the current time. The interval between time t1 and time t2 may be 3s, 5s, 7s, etc., or other time intervals, which may be preset based on actual needs. After collecting the first discharge current, the first discharge voltage, the second discharge current, and the second discharge voltage, the data acquisition module sends them to the data analysis module.

[0124] S506: The data analysis module determines the target battery at t based on the first discharge current and the first discharge voltage. 1 The first discharge resistor at the moment.

[0125] S508: The data analysis module determines the target battery at t based on the second discharge current and the second discharge voltage. 2 The second discharge resistor at this moment.

[0126] Specifically, the discharge resistance is determined by the following formula:

[0127] R=VI,

[0128] Where R is a discharge resistor (a first discharge resistor or a second discharge resistor), V is a discharge voltage (determining a first discharge voltage of the first discharge resistor or determining a second discharge voltage of the second discharge resistor), and I is a discharge current (determining a first discharge current of the first discharge resistor or determining a second discharge current of the second discharge resistor);

[0129] S510: The data analysis module determines a resistance variation trend of the target battery based on the first discharge resistor and the second discharge resistor.

[0130] S512: When the resistance change trend does not meet the target resistance change trend, the data analysis module determines that the health state of the target battery is abnormal.

[0131] In one example, if the internal resistance of the target battery needs to be controlled between 0.2 and 0.5 ohms. As the battery is used and aged, the internal resistance will gradually increase. If the measured internal resistance value is much larger than this range, for example, from 0.5 ohms of the first discharge resistor to 4 ohms of the second discharge resistor, it may indicate that the performance of the target battery has declined, and the health status of the target battery is analyzed to be abnormal.
