[0001] The present application relates to the field of charging control technology, and in particular to a charging control method, an electronic device and a storage medium. Background Art

[0002] Currently, most battery packs use PTC resistors during the charging and heating process. However, PTC resistors have the characteristic of relatively large initial heating power, which causes the initial heating current to be larger than the normal heating current required.

This leads to the battery pack being easily charged during low-temperature heating, or the initial heating does not meet the heating current requirement, resulting in the problem of battery pack discharge heating.

[0038] 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 those skilled in the art without creative work are within the scope of protection of this application.

[0039] Embodiments of the present application provide a charging control method, device, electronic device, and storage medium.

[0040] Among them, the charging control method can be specifically applied in a terminal, which may include a tablet computer or a personal computer (PC). The terminal can establish a wired or wireless connection with a server. The server may include an independently running server or a distributed server, or may include a server cluster composed of multiple servers.

[0041] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0042] A charging control method includes: in response to a charging operation for a target battery, obtaining a preset charging mapping table; determining a reference charging current value corresponding to the target battery in the charging mapping table according to the battery state of the target battery; comparing the reference charging current value with a preset reference current value; determining a charging strategy corresponding to the target battery according to the comparison result, and charging the target battery based on the charging strategy.

[0043] See also Figure 1 , Figure 1This is a flow chart of a charging control method provided in an embodiment of the present application. The specific flow of the charging control method may be as follows:

[0044] 101. In response to a charging operation on a target battery, obtain a preset charging mapping table.

[0045] A charging map is a table pre-defined by a battery manufacturer or a battery management system (BMS) developer to guide the battery charging process. The charging map contains recommended charging current values ​​under different battery conditions, such as the battery's state of charge (SOC), temperature, voltage, etc. By specifying appropriate charging currents for different battery conditions, the charging map helps prevent overcharging or overheating, thereby protecting the battery from damage. The charging map can adjust the charging current based on the actual state of the battery to achieve faster charging speeds while avoiding unnecessary stress on the battery. By precisely controlling the charging process, the charging map helps reduce battery aging and extend the battery's service life. The charging map can adjust the charging strategy based on changes in external conditions such as ambient temperature to ensure safe and efficient charging under different conditions.

[0046] When the charging requirements are met, the battery management system (BMS) will start the charging process. After the charging process starts, there will be a 2-second delay to ensure that the charging system is stable. During the charging process, the BMS will determine the reference charging current value (Imap) corresponding to the target battery according to the preset charging map (charging map). This charging map is pre-set and contains recommended current values ​​under different charging conditions.

[0047] Optionally, in some embodiments of the present application, the step of “obtaining a preset charging mapping table in response to a charging operation on a target battery” may specifically include:

[0048] In response to a charging operation for the target battery, a preset charging mapping table is acquired after a preset time.

[0049] The preset time can be set according to actual conditions, such as considering the output capacity and response time of the charging device, to ensure that the charging process matches the specifications of the charging device.

[0050] 102. Determine a reference charging current value corresponding to the target battery in a charging mapping table according to the battery state of the target battery.

[0051] For example, the battery management system (BMS) monitors the status of the target battery in real time, including key parameters such as the battery's state of charge (SOC), temperature, and voltage. The BMS accesses a preset charging map, which contains recommended charging current values ​​under different battery states. Based on the current state of the target battery (such as SOC, temperature, etc.), the BMS searches the charging map for the corresponding reference charging current value (Imap).

[0052] Optionally, in some embodiments of the present application, the step of “determining a reference charging current value corresponding to the target battery in a charging mapping table according to the battery state of the target battery” may specifically include:

[0053] Determine the charge information and temperature information of the target battery according to the battery state of the target battery;

[0054] Based on the charge information and the temperature information, a reference charging current value corresponding to the target battery is determined in the charging mapping table.

[0055] For example, the SOC of the target battery is 50% and the temperature is 25°C. The BMS will look up the charging current value corresponding to SOC 50% and 25°C in the charging mapping table. According to the charging mapping table, the recommended charging current value corresponding to SOC 50% and 25°C is 4A.

[0056] 103. Compare the reference charging current value with a preset reference current value.

[0057] The reference current value refers to a preset current threshold value, which is used to compare with the reference charging current value of the battery to determine the charging strategy. The reference current value is a parameter in the battery management system (BMS), which helps the BMS determine how to adjust the charging current in different situations to optimize the charging process and protect the battery. Optionally, in some embodiments of the present application, the reference current value is 5A.

[0058] 104. Determine a charging strategy corresponding to the target battery according to the comparison result, and charge the target battery based on the charging strategy.

[0059] For example, the reference charging current value (Imap) of the battery is compared with a preset reference current value. If the reference charging current value is greater than or equal to the reference current value, select charging strategy A, such as charging directly according to the charging map. If the reference charging current value is less than the reference current value, select charging strategy B, including reducing the charging current or starting a battery heating program. According to the selected charging strategy, adjust the charging parameters, such as current and voltage, to adapt to the current state and charging needs of the battery.

[0060] Optionally, in some embodiments of the present application, the step of “determining a charging strategy corresponding to the target battery according to the comparison result, and charging the target battery based on the charging strategy” may specifically include:

[0061] When the reference charging current value is greater than or equal to the reference current value, a preset charging strategy is acquired, and the target battery is charged based on the preset charging strategy;

[0062] When the reference charging current value is less than the base current value, it is detected whether a heating signal exists, and the target battery is charged according to the detection result and a preset charging strategy.

[0063] For example, if Imap is greater than or equal to the reference current value, the BMS will consider that the battery can accept higher current charging under the current conditions. Obtain the preset charging strategy, that is, you can charge according to the higher current value recommended in the charging mapping table. Perform the charging operation to charge the battery with the recommended current value. If Imap is less than the reference current value, the BMS will consider that the battery cannot accept higher current charging under the current conditions, and heating charging is required.

[0064] Optionally, in some embodiments of the present application, the step of “when the reference charging current value is greater than or equal to the reference current value, obtaining a preset charging strategy, and charging the target battery based on the preset charging strategy” may specifically include:

[0065] When the reference charging current value is greater than or equal to the reference current value, a preset charging strategy is obtained;

[0066] Determine the charging current formula corresponding to the charging strategy;

[0067] The target battery is charged based on the charging current formula.

[0068] When the reference charging current value (Imap) is greater than or equal to the reference current value (e.g. 5A), the BMS will obtain the preset charging strategy. This strategy usually refers to charging according to the current value recommended in the charging mapping table. When Imap is greater than or equal to 5A, the BMS will enter the current following strategy. The charging current formula of the current following strategy can be: active =I map +(I active '-I)

[0069] Among them, Iactive is the currently requested charging current value, Imap is the recommended current value (i.e. reference current value) in the charging mapping table, and I active ' is the requested current value at the previous moment, and I is the current value detected by the BMS at present.

[0070] For example, the SOC of the target battery is 60% and the temperature is 20°C. According to the charging mapping table, the Imap in this state is 6A. Assume that the requested current value I active ' is 5A, and the current value I detected by the BMS is 4A. Based on the above formula, the current requested charging current value is 7A, so the BMS will request a charging current of 7A to charge the target battery.

[0071] Optionally, in some embodiments of the present application, the step of “charging the target battery according to the detection result and a preset charging strategy” may specifically include:

[0072] When a heating signal is detected, the target battery is heated and charged according to the preset heating time and the current corresponding to the reference current value;

[0073] During the heating charging process, the current value of the shunt is monitored, and if the current value of the shunt meets a first preset condition, the target battery is charged based on a preset charging strategy;

[0074] The current value of the shunt is monitored after the heating charging process, and if the current value of the shunt meets a second preset condition, the target battery is charged based on a preset charging strategy.

[0075] In a battery management system (BMS), a heating signal is an important indication that the battery needs to increase its temperature to meet specific operating or charging conditions. Under low temperature conditions, the battery's charging efficiency will decrease. The heating signal can help increase the battery temperature, thereby improving charging efficiency. Low temperatures can damage the battery, especially during charging. The heating signal ensures that the battery operates within a safe temperature range to avoid damage caused by low temperatures.

[0076] A shunt resistor is an electronic component that is usually used to measure the current in a circuit. In a battery management system (BMS), the main function of a shunt is to measure the charge and discharge current of a battery pack or a single battery cell.

[0077] When the BMS (battery management system) detects the presence of a heating signal, it indicates that the battery needs to be heated to meet the charging conditions. According to the preset heating time and the reference current value (for example, 5A), the BMS will heat and charge the target battery. During the heating and charging process, the BMS will continue to monitor the current value of the shunt. If the current value of the shunt meets the first preset condition (for example, the current value is greater than 2A and lasts for 2 seconds), this may indicate that the battery has reached a sufficient temperature to start the normal charging process. If the first preset condition is met, the BMS will charge the target battery based on the preset charging strategy. Monitoring after heating and charging: When the preset heating time is reached, the BMS will stop heating and charging and continue to monitor the current value of the shunt.

[0078] If the current value of the shunt meets the second preset condition (for example, the current value is less than or equal to 2A and does not exceed 2 seconds), this may indicate that the battery temperature has not yet reached the charging requirement or the battery needs further heating. If the second preset condition is met, the BMS will charge the target battery again based on the preset charging strategy, such as restarting the heating program or adjusting the charging current to adapt to the current state of the battery.

[0079] For example, specifically, the battery temperature of the electric vehicle drops to 0°C, which is 5°C lower than the minimum temperature required for charging. The BMS detects a heating signal to protect the battery and improve charging efficiency. The BMS starts the heating system and heats and charges the battery with a reference current value of 5A for a preset heating time of 60 seconds. During the heating and charging process, the BMS continuously monitors the current value of the shunt. For example, at the 30th second of the heating and charging, the current value of the shunt suddenly increases to 3A and lasts for more than 2 seconds. The BMS determines that the battery temperature is sufficient and normal charging can begin. The BMS charges the battery according to a preset charging strategy (such as the recommended current value in the charging mapping table). For example, the charging mapping table recommends a charging current value of 4A at the current temperature, and the BMS will request a current of 4A to charge the battery.

[0080] After the heating charge is completed, the BMS continues to monitor the current value of the shunt. For example, if the current value of the shunt drops to 1.5A after the heating charge is completed and lasts for no more than 2 seconds, the BMS determines that the battery may need further heating or is already in a suitable charging state. If the charging mapping table recommends a charging current value of 3A at the current temperature, the BMS will request a current of 3A to charge the battery. When the battery reaches a fully charged state or the charging conditions are no longer met, the BMS will terminate the charging process.

[0081] Optionally, in some embodiments of the present application, the step of “monitoring the current value of the shunt during the heating charging process, and if the current value of the shunt meets the first preset condition, charging the target battery based on a preset charging strategy” may specifically include:

[0082] Monitor the current value of the shunt during the heating and charging process;

[0083] If the current value of the shunt is greater than the preset value, and the duration for which the current value of the shunt is greater than the preset value is greater than the preset duration, the target battery is charged based on a preset charging strategy.

[0084] For example, during the heating charging process, the BMS checks whether the current value of the shunt is greater than the preset value (for example, 2A). If the current value is greater than the preset value, the BMS further checks whether this state lasts for a preset time (for example, 2 seconds). If the current value of the shunt is greater than the preset value and lasts for more than the preset time, the BMS believes that the battery has reached a suitable charging temperature, and the BMS will charge the target battery based on the preset charging strategy. During the entire charging process, the BMS will continue to monitor the status of the battery, including SOC, temperature, and current, to ensure that the charging process is safe and efficient. When the battery reaches a fully charged state or the charging conditions are no longer met, the BMS will terminate the charging process.

[0085] Optionally, in some embodiments of the present application, the step of “monitoring the current value of the shunt after the heating charging process, and if the current value of the shunt meets the second preset condition, charging the target battery based on a preset charging strategy” may specifically include:

[0086] Monitor the current value of the shunt after the heating charging process;

[0087] If the current value of the shunt is less than or equal to the preset value, and the duration for which the current value of the shunt is less than or equal to the preset value is less than or equal to the preset duration, the target battery is charged based on a preset charging strategy.

[0088] The BMS checks whether the current value of the shunt is less than or equal to a preset value (e.g. 2A). If the current value is less than or equal to the preset value, the BMS further checks whether this state lasts for a preset time (e.g. 2 seconds). If the current value of the shunt is less than or equal to the preset value and the duration is less than or equal to the preset time, the BMS believes that the battery may need further heating or is already in a suitable charging state. The BMS will charge the target battery based on a preset charging strategy. The strategy can be to adjust the charging current to match the recommended value in the charging mapping table.

[0089] To further understand the charging control scheme of this application, please refer to Figure 2, which will be further explained below. When the charging requirements are met, the charging process is entered. After a delay of 2s, the size of the charging map and the 5A current is determined. If the charging map>=5A, the charging current is requested according to the charging map, and the current following strategy is entered, and the charging current is requested according to Iactive=Imap+(Iactive'-I). When the charging map<5A, it is determined whether the BMS has a Heating signal. If the BMS does not issue a Heating signal, the current following strategy is entered, and the charging current is requested according to Iactive=Imap+(Iactive'-I). If the BMS issues a Heating signal, the 5A current is continuously requested for 60s (60s is the starting point of T timing when the Heating signal is issued). If the BMS detects that the shunt current is greater than 2A and lasts for 2s (2A is the discharge current) within 60s, the current following strategy is entered, and the charging current is requested according to Iactive=Imap+(Iactive'-I). If the BMS detects that the shunt current is ≤2A and does not exceed 2s (2A is the discharge current) after 60s, the BMS directly enters the current following strategy.

[0090] It should be noted that current following is a control strategy in the battery management system (BMS), which dynamically adjusts the battery's charge or discharge current to adapt to the battery's current state and external conditions. The specific process is as follows:

[0091] After the charging conditions are met, the BMS starts the charging process.

[0092] BMS dynamically adjusts the charging current according to the real-time status of the battery and the charging map.

[0093] The BMS continuously monitors the battery status and adjusts the current based on feedback to ensure battery safety and charging efficiency.

[0094] For example, in a low temperature environment, the reference charging current value (Imap) of the battery is 4A, while the reference current value is 5A. According to the current following strategy: If Imap (4A) is less than the reference current value (5A), the BMS starts the heating system to increase the battery temperature. During the heating process, if the current value of the shunt shows that the battery has begun to heat up (for example, the current value is greater than 2A and lasts for 2 seconds), the BMS will adjust the charging current according to the new current value recommended by the charging mapping table (for example, Imap becomes 5A after heating). If the current value after heating meets the preset conditions (for example, less than or equal to 2A and the duration is less than or equal to 2 seconds), the BMS will continue charging according to the new charging strategy.

[0095] The embodiment of the present application provides a charging control method, in response to a charging operation for a target battery, after obtaining a preset charging mapping table, according to the battery state of the target battery, a reference charging current value corresponding to the target battery is determined in the charging mapping table, then the reference charging current value is compared with the preset reference current value, and finally, the charging strategy corresponding to the target battery is determined according to the comparison result, and the target battery is charged based on the charging strategy. The charging control scheme provided by the present application determines the charging strategy corresponding to the target battery according to the difference between the reference charging current value and the preset reference current value, and charges the target battery based on the charging strategy, which can meet the effect of the current entering the battery pack being consistent with the charging mapping table, and solves the charging or discharging heating problem during low-temperature charging heating, thereby not only improving the charging heating efficiency, but also not damaging the life of the battery pack.
