Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery SOC full charge correction method and related devices. Background Art

[0002] In the battery management system, full charge correction is an important correction algorithm for estimating the SOC (State Of Charge) during the battery charging process. When the voltage reaches the full charge voltage, the battery is considered to be fully charged and the SOC can be set to 100.

[0003] However, when the battery is fully charged and a small amount of power is used, it enters a static state. The battery voltage will decrease as the static time increases. At this time, if the battery is charged again, it will be in a high SOC. According to the battery cell map, the charging current will be smaller, and the battery voltage will not reach the charging cut-off voltage for a long time due to the large drop. If it is charged with a small current for a long time, the battery cell life will be shortened due to overcharging. Summary of the invention

[0041] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0042] In order to make the purpose, technical solutions and advantages of the present application clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0043] See also Figure 1 , which shows a flow chart of the implementation of the battery SOC full correction method provided by the embodiment of the present application, which is described in detail as follows:

[0044] S101: Monitor the actual SOC value of the battery.

[0045] The execution subject (electronic device) of this embodiment may be a battery management system.

[0046] Specifically, during the battery charging and discharging process, the battery management system can monitor the actual SOC value of the battery in real time. The actual SOC value can be calculated based on conventional SOC estimation methods such as ampere-hour integration algorithm, Kalman filtering method or neural network method.

[0047] S102: If the actual SOC value of the battery is greater than a first preset threshold, when either the voltage value or the actual SOC value of the battery satisfies a corresponding battery full condition, the displayed SOC value of the battery is set to a full-scale value.

[0048] Specifically, the first preset threshold value can be a value close to the full scale, such as 99%. If the actual SOC value of the battery at the current moment is greater than the first preset threshold value, it means that the battery is currently in a state of high power, and the battery will be charged with a smaller current, then the change rate of the SOC value (current integral value) will be greater than the change rate of the charging voltage. If the battery is charged with a small current for a long time, it will cause overcharging problems, and if the battery displays a SOC value that remains at 99% for a long time without changing, it will cause users to doubt the reliability of the battery.

[0049] In order to avoid the above problems, this embodiment determines whether the battery is fully charged from two perspectives, namely, the battery voltage value and the actual SOC value, when it is monitored that the actual SOC value of the battery is greater than the first preset threshold value. That is, when the battery is in a high power state, two battery full charge judgment conditions are selected. As long as any one of the battery full charge judgment conditions is met, the battery is considered to be fully charged. The battery management system controls the battery to stop charging and corrects the displayed SOC value of the battery to 100%. This not only avoids the problem of battery overcharging, but also accurately determines whether the battery is fully charged, thereby avoiding the problem of undercharging and improving the accuracy of full charge correction of the battery SOC.

[0050] Specifically, the above steps S101 - S102 may be performed at various times during the battery charging process.

[0051] It can be seen from the above embodiments that the embodiments of the present application first monitor the actual SOC value of the battery; if the actual SOC value of the battery is greater than the first preset threshold value, then when either the voltage value or the actual SOC value of the battery meets the corresponding battery full condition, the displayed SOC value of the battery is set to the full-scale value. Through the above scheme, the present application can avoid the battery overcharging problem caused by the battery voltage failing to reach the cut-off voltage when the battery SOC is high.

[0052] In a possible implementation, the battery full condition corresponding to the voltage value is that the battery voltage value reaches the charge cut-off voltage, and the battery full condition corresponding to the actual SOC value is that the actual SOC value of the battery is equal to the full-scale value.

[0053] In this embodiment, the full scale value may be 100%.

[0054] In a possible implementation, the method provided in this embodiment further includes:

[0055] If the actual SOC value of the battery is less than the first preset threshold, whether the battery is fully charged is determined based on the voltage value of the battery.

[0056] In this embodiment, if the actual SOC value of the battery at the initial moment of operation is not greater than the first preset threshold, it can be determined whether the battery is fully charged based on conventional full charge determination conditions (eg, voltage determination conditions).

[0057] In a possible implementation, the specific implementation process of the above method includes:

[0058] If the monitored battery voltage reaches the charge cut-off voltage, it is determined that the battery is fully charged.

[0059] In a possible implementation manner, the specific implementation process of S101 includes:

[0060] Get the current value of the battery;

[0061] The actual SOC value of the battery is calculated based on the ampere-hour integration method and the current value of the battery.

[0062] In this embodiment, the calculation formula of the actual SOC value of the battery can be:

[0063] Among them, SOC t Indicates the actual SOC value of the battery at time t, SOC t-1 It represents the actual SOC value of the battery at time t-1, i represents the current value of the battery at time t, and when i is positive, it represents the charging current value, and when i is negative, it represents the discharging current value; C can select the rated capacity of the battery, or the maximum available capacity of the battery; the rated capacity of the battery refers to all the capacity values ​​that can be discharged by a new fully charged battery pack at a preset discharge rate at normal temperature; the maximum available capacity of the battery refers to all the capacity values ​​that can be discharged by the battery from a fully charged state at a preset discharge rate at the current of the battery's current temperature.

[0064] Preferably, the above C value can be taken as the maximum available capacity of the battery at the current temperature.

[0065] Specifically, the battery management system first obtains the temperature value of the battery at the current moment. In order to ensure the safe operation of the battery, the minimum value of the temperature values ​​corresponding to each battery in the battery pack at the current moment can be selected as the temperature value of the entire battery at the current moment. Then, according to the temperature value of the battery at the current moment, the preset temperature-capacity table is queried to obtain the available capacity corresponding to the battery at the current temperature value; finally, the available capacity obtained from the table is multiplied by the health of the battery at the current moment to obtain the maximum available capacity corresponding to the battery at the current moment.

[0066] In one embodiment, the specific implementation process of S102 further includes:

[0067] If the actual SOC value of the battery at the initial moment of operation is greater than the first preset threshold, the displayed SOC value of the battery is set to the full-scale value when either the voltage value or the actual SOC value of the battery meets the corresponding battery full condition.

[0068] In this embodiment, the situation that the actual SOC value of the battery reaches 100% but the charging voltage does not reach the charging cut-off voltage usually occurs when the battery is charged again after being left for a period of time but the power is still high. Therefore, this embodiment can directly monitor whether the actual SOC value of the battery at the initial moment of operation is greater than the first preset threshold value. If it is greater, then in each cycle of the subsequent charging process of the battery, either the battery voltage or the actual SOC value is used to determine whether the battery is fully charged; if the actual SOC value of the battery at the initial moment of operation is not greater than the first preset threshold value, the above situation usually does not occur, so it can be directly determined based on the size of the battery voltage whether the battery is fully charged, thereby reducing the calculation amount of this solution.

[0069] It can be seen from the above embodiments that the present application distinguishes the actual power state of the battery by considering the size of the battery SOC, and selects different battery full charge correction methods according to the actual power state of the battery, which can effectively avoid not considering the state of SOC at this time when making the battery full charge correction, and simply using the voltage reaching the charging cut-off voltage as the basis for judgment, causing the battery to be overcharged and resulting in a shortened battery life, and insufficient undercharging causing customer complaints, and other problems, thereby providing customers with more power while ensuring the safety of the battery.

[0070] 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.

[0076] In a possible implementation, the battery full condition corresponding to the voltage value is that the battery voltage value reaches the charge cut-off voltage, and the battery full condition corresponding to the actual SOC value is that the actual SOC value of the battery is equal to the full-scale value.

[0077] In a possible embodiment, the battery SOC full correction device 100 further includes:
