Description

Technical Field

[0001] This disclosure relates to the field of power management technology, and in particular to a discharge method and apparatus, electronic equipment, and storage medium. Background Technology

[0002] As smart devices become essential for people's work and life, their power consumption has increased rapidly, necessitating frequent charging.

[0003] In related technologies, increasing the charging current can improve charging efficiency and shorten charging time. However, high-current charging increases cell power consumption, leading to higher battery temperatures, which in turn affects charging efficiency and cell lifespan.

[0004] To address this, related technologies convert multiple battery cells in a smart terminal into two strings of cells, increasing the charging voltage of each string (e.g., doubling the original) and decreasing the charging current (e.g., halving the original).

[0055] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described below by way of example do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatus consistent with some aspects of this disclosure as detailed in the appended claims.

[0056] Considering that when charging cells in series, the two cells may have different voltages due to differences in remaining charge and / or internal impedance, the cell with the higher voltage may be overcharged or even damaged.

[0057] To address the aforementioned technical problems, this disclosure provides a discharge method. Figure 1 This is a flowchart illustrating a discharge method according to an exemplary embodiment, applicable to electronic devices such as smartphones, tablets, and personal computers, wherein the electronic device includes multiple battery cells. See also Figure 1 A discharge method, comprising steps 11 to 14, wherein:

[0058] In step 11, in response to determining that a charging operation has been detected, the plurality of cells are switched to series charging mode.

[0059] In this embodiment, the electronic device can connect to an external charging device through its own interface module (such as a Mini USB interface module, MicroUSB interface module, Type-C interface module, Lightning interface module) or wireless module. After connection, the electronic device and the external charging device can handshake according to a preset charging protocol (such as Quick Charge, Power Delivery, etc.). After successful handshake, the electronic device can receive the power output by the charging device.

[0060] Understandably, the handshake process between the electronic device and the charging device can be seen as a process by which the electronic device detects a charging operation. A failed handshake indicates a failure to establish a charging channel, while a successful handshake indicates a successful establishment of the charging channel. When the charging channel is successfully established, the electronic device can confirm that a charging operation has been detected.

[0061] In this embodiment, the electronic device can switch multiple battery cells to a series charging mode in response to detecting a charging operation. See also Figure 2 In step 21, the electronic device can send control information to each switching device, which is used to turn the switching devices on or off, causing multiple battery cells to switch to series mode. In step 22, the electronic device can send first charging control information to the charging device, so that the charging device outputs the charging voltage and charging current corresponding to the series mode. At this time, the charging device supplies power to both the battery cells and the load simultaneously.

[0062] In this embodiment, the number of multiple battery cells can be set according to the specific scenario, such as 2, 3, 4, 8, or even more, and is not limited here. Furthermore, the electronic device also includes multiple switching devices that can be turned on or off. By controlling the on or off state of each switching device, the connection relationship of the multiple battery cells can be adjusted, allowing the multiple battery cells to switch to series mode or parallel mode. The series-parallel hybrid mode also falls under the category of parallel mode.

[0063] Taking an electronic device consisting of two battery cells (in series) as an example, see [link to relevant documentation]. Figure 3 The electronic device can control the first switching device K1 to turn on, while simultaneously controlling the second switching device K2 and the third switching device K3 to turn off. The equivalent circuit is as follows: Figure 4 As shown. Then, the electronic device can send first charging control information to the charging device. For example, the processor of the electronic device sends the first charging control information to the charging device through the charging circuit, so that the charging device outputs the charging voltage and charging current corresponding to the series mode. At this time, the charging device supplies power to cell 1, cell 2, and the load respectively.

[0064] It should be noted that the first switching device K1, the second switching device K2, and the third switching device K3 mentioned above can be implemented using devices such as transistors and field-effect transistors, and no limitation is made here.

[0065] Taking an electronic device with four battery cells as an example, battery cell 1 and battery cell 2 can be considered as a battery cell string. That is, battery cell 1 can include two cells 1A and 1B, and battery cell 2 can include two cells 2A and 2B. Taking battery cell 1 as an example, the circuit connection method of battery cell 1A and battery cell 1B can refer to the connection method of battery cell 1 and battery cell 2. By controlling the conduction and disconnection of the switching device, the four battery cells 1A, 1B, 2A, and 2B can be connected in series for charging.

[0066] In step 12, in response to the load power of the electronic device exceeding the actual power provided by the external charging device, a designated cell among the plurality of battery cells is controlled to discharge, and the designated cell and the charging device simultaneously supply power to the electronic device.

[0067] In this embodiment, the electronic device can acquire its load power, which can be obtained by statistically analyzing the user power of each load. The load may include a CPU, display, motherboard circuitry, etc. The electronic device can compare the actual power of the charging device with the load power of the electronic device. When the load power is less than the actual power, detection continues; when the load power is greater than or equal to the actual power, the electronic device controls a designated battery cell among multiple battery cells to discharge. In this way, the designated battery cell and the external device simultaneously supply power to the load of the electronic device, ensuring the load's power requirements are met. See also... Figure 5 The actual power P of the charging circuit is divided into two parts: power P1 is provided to cell 1, power P2 is provided to the load, and power P3 is provided by cell 2 to the load. The power obtained by the load is P2 + P3.

[0068] It should be noted that the designated battery cell can include at least one of the following: a battery cell randomly selected by the electronic device, a battery cell determined according to the discharge sequence, a battery cell with the highest voltage, a battery cell with the highest charge, or a battery cell with the fewest uses. This can be set according to the specific scenario and is not limited here. In one example, the designated battery cell is a battery cell with its negative terminal directly grounded, such as... Figure 5 As shown in cell 2, the positive terminal voltage of the specified cell can supply power to the load without adjusting the voltage of its negative terminal.

[0069] In step 13, preset parameter data of some of the multiple battery cells are detected.

[0070] In this embodiment, the electronic device can use a preset fuel gauge to detect preset parameter data of some battery cells. These "some battery cells" may include designated battery cells; for example, the electronic device may measure only the preset parameter data of designated battery cells, or it may simultaneously measure the preset parameter data of designated battery cells and other battery cells. It is understood that the battery cells whose preset parameter data are being detected can be determined based on subsequent preset conditions, and this is not limited here.

[0071] The preset parameter data may include one of the following: relative voltage, relative quantity, absolute voltage, or absolute quantity. Technicians can select appropriate preset parameter data based on the specific scenario, and the corresponding solution falls within the protection scope of this disclosure.

[0072] In step 14, when the preset parameter data meets the preset conditions, at least the cells in the series branch where the specified cell is located are switched to parallel mode for discharge.

[0073] In this embodiment, the electronic device can store preset conditions. These preset conditions refer to the following: the difference between preset parameter data is greater than a preset parameter threshold; the difference between preset parameter data is greater than the preset parameter threshold and remains greater than the preset parameter threshold for a preset duration; and the preset parameter data of a specified battery cell is less than or equal to the preset threshold. The preset duration ranges from 5 to 50 seconds and can be selected according to the specific scenario.

[0074] After acquiring the preset parameter data, the electronic device can process the preset parameter data of two cells in any series branch, such as calculating the difference between the preset parameter data of the two cells; and determine whether the preset parameter data of the two cells meets the preset conditions. If the difference between the preset parameter data is less than or equal to the preset parameter threshold, it is determined that the preset conditions are not met, and the electronic device can return to step 12. If the difference between the preset parameter data is greater than the preset parameter threshold, it is determined that the preset conditions are met. When the preset conditions are met, the electronic device can switch the cells in the series branch containing the two cells to parallel mode for discharge. At this time, the charging device controls the designated cell to discharge, that is, the designated cell and the charging device simultaneously supply power to the load, while the charging device charges other cells in other series branches and other cells in the series branch containing the designated cell. Alternatively, when the preset conditions are met, the electronic device can switch all cells to parallel mode for discharge, and the charging device and all cells simultaneously supply power to the load.

[0075] After obtaining the preset parameter data of a specified battery cell, the electronic device can process the preset parameter data of the specified battery cell, such as calculating whether the preset parameter data of the specified battery cell is less than a preset data. The preset data can be a digital threshold (e.g., 3.75V) or a proportional threshold (e.g., 65%). If the preset parameter data is greater than the preset threshold, it is determined that the preset condition is not met, and the electronic device can return to step 12. If the preset parameter data is less than or equal to the preset threshold, it is determined that the preset condition is met. When the preset condition is met, the electronic device can switch the cells in the series branch containing the specified battery cell to parallel mode for discharge. At this time, the charging device controls the discharge of the specified battery cell, meaning that the specified battery cell and the charging device simultaneously supply power to the load, while the charging device charges other cells in other series branches and other cells in the series branch containing the specified battery cell. Alternatively, when the preset condition is met, the electronic device can switch all battery cells to parallel mode for discharge, and the charging device and all battery cells simultaneously supply power to the load.

[0076] See Figure 6In step 61, the electronic device can send control information to each switching device. This control information is used to turn the switching devices on or off, causing multiple battery cells to switch to parallel mode. In step 62, the electronic device can obtain the target output power of each battery cell based on the actual power provided by the charging device. In step 63, the electronic device can output discharge control information to each battery cell, which is used to make each battery cell output the target power. In this way, the charging device and multiple battery cells simultaneously supply power to the load of the electronic device. During the power supply process, the multiple battery cells in parallel mode can achieve automatic voltage balancing, ensuring the normal operation of the battery cells.

[0077] Continuing with the example of two battery cells, the electronic device can control the first switching device K1 to open, while simultaneously controlling the second switching device K2 and the third switching device K3 to open. The equivalent circuit is as follows: Figure 6 As shown in the diagram. Then, the electronic device can send control signals to battery cells 1 and 2, causing them to output the target power, ultimately achieving voltage balance. At this time, the charging device provides power P to the load, battery cell 1 provides power P1 to the load, and battery cell 2 provides power P2 to the load; that is, the power received by the load is P + P1 + P2. The equivalent circuit is shown in the diagram. Figure 7 As shown.

[0078] Continuing with the example of four battery cells, switch the four cells to parallel mode, including:

[0079] In one example, by controlling the switching device to turn on and off, the four battery cells are divided into two strings: battery cell 1A and battery cell 1B are connected in series to form the first battery cell string, and battery cell 2A and battery cell 2B are connected in series to form the second battery cell string. The first battery cell string and the second battery cell string are then connected in parallel to form a... Figure 6 The structure shown depicts four battery cells connected in both series and parallel configurations. Subsequently, each string of two cells supplies power to the load of the electronic device. In this example, the parallel connection of the cells can be understood as switching to an associative mode.

[0080] In another example, by controlling the switching device to turn on and off, the four cells are directly switched to parallel mode, at which point the four cells and the charging device simultaneously power the load of the electronic device.

[0081] Therefore, in this embodiment of the present disclosure, when a charging operation is detected, multiple battery cells can be switched to series charging mode in response to the detection of the charging operation; during the charging process, if the load power of the electronic device is detected to exceed the actual power provided by the charging device, a designated battery cell is controlled to discharge, thereby compensating for the insufficient power of the charging device; during the discharge of the designated battery cell, there may be a situation where the preset parameter data of the battery cell meets the preset conditions. At this time, the battery cell of the corresponding series branch is switched to parallel discharge mode, thereby balancing the preset parameter data of each battery cell and ensuring battery safety.
