[0021] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the present application is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present application. The described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0024] With the increasing prevalence of various mobile electronic devices, such as mobile phones and tablets, the demand for charging these devices has also increased. Therefore, batteries for charging these devices have become increasingly important. Especially when outdoors, users often carry portable energy storage devices such as power banks to prevent their devices from running out of power. Portable energy storage devices that can charge electronic devices include power banks and other portable energy storage devices (also known as outdoor power banks). Power banks are typically small-capacity energy storage devices, with their capacity typically measured in milliampere-hours (mAh). Power banks, on the other hand, have a larger capacity than power banks, typically measured in watt-hours (Wh). However, with the development of larger-capacity power banks and the expansion of smaller-capacity power banks, some power banks now have capacities approaching or even exceeding those of some power banks.

[0025] Portable energy storage devices may also include battery packs (also referred to as battery modules) that can be removed from various electronic devices and discharged independently. For example, battery packs can be used in self-moving devices such as automotive equipment, lawn mowing equipment, sweeping equipment, and cruise equipment. They can also be used in energy storage devices such as mobile energy storage devices and household energy storage devices, without limitation. Whether it is a power bank, a mobile power supply, or a detachable and independently used battery pack, they are all collectively referred to as portable energy storage devices in this application.

[0026] FIG1 is a schematic diagram of a portable energy storage device 110 in one embodiment. Referring to FIG1 , the portable energy storage device 110 includes a housing (not shown in the figure), a battery cell module 111, a DC / DC conversion module 112, an input / output module 113, and a control module 114. The battery cell module 111 includes a battery cell group and a battery management system BMS (not shown in the figure). The battery management system BMS is used to control the charging and discharging of the battery cell group, and to implement protection of the battery cells against over-temperature, low temperature, overvoltage, overcurrent, undervoltage, etc. The battery cell group may include a single battery cell, or two or more battery cells. The number of battery cells is determined based on the capacity of a single battery cell and the capacity that the portable energy storage device 110 needs to achieve. The input / output module 113 may include at least one of an input interface, an output interface, and a bidirectional interface. Both the input interface and the output interface may include a wired interface and a wireless interface, or may include only one of them. That is, the input / output module 113 can be connected to electronic devices such as electronic devices that need to be charged, or it can be connected to power supply devices that can charge portable energy storage devices, such as chargers or other energy storage devices. The DC / DC conversion module 112 is used to boost or buck the DC power provided by the battery module 111 and then charge the connected electronic device through the input / output module 113, or use the connected energy storage device to buck or boost the DC power provided by the energy storage device and then output it to the battery module 111 for charging. The DC / DC conversion module 112 can adopt a bidirectional buck-boost circuit, or a single buck or single boost circuit, which is mainly determined by its battery cell voltage and the voltage range supported by the input / input module 113. The control module 114 is used to control the entire portable energy storage device 110 so that the portable energy storage device 110 can operate in the expected state.

[0027] In another embodiment, as shown in FIG2 , the portable energy storage device 110 may further include a wireless communication module 115. The wireless communication module 115 may communicate with other devices having wireless communication functions after wireless connection. For example, the portable energy storage device 110 may wirelessly communicate with the connected electronic device through the wireless communication module 115, thereby obtaining status parameters of the electronic device, etc., so that the portable energy storage device 110 can obtain the current status of the electronic device. In one embodiment, if an application for managing the portable energy storage device 110 is installed in the electronic device or other unconnected electronic device, the portable energy storage device 110 may also receive instructions from the application through the wireless communication module 115 and respond; or send response prompt information, request information and status parameters to the application, etc. At this time, the user can manage the portable energy storage device 110 through the application.

[0028] It is understood that the wireless communication module 115 may include at least one of a Bluetooth module, a WIFI module, a ZigBee module, a cellular network, etc. The portable energy storage device 110 may also be provided with other communication modules as needed, which are not limited here.

[0029] Figure 3 is an example diagram of a portable energy storage device charging an electronic device. Referring to Figure 3, the portable energy storage device 110 can be connected to an electronic device 120 such as a mobile phone via a charging cable 130, so that the portable energy storage device 110 charges the electronic device 120. At this time, the portable energy storage device 110 needs to be provided with a corresponding discharge interface, such as a Type C interface, a Type A interface, and a Lighting interface. There can be one or more discharge interfaces to support charging of one or more electronic devices. For simplicity, the figure only shows a schematic diagram of the portable energy storage device 110 charging an electronic device 120. In one embodiment, the portable energy storage device can also be provided with a slot structure for fixing the charging cable 130, so that the user can remove the charging cable 130 from the slot structure when needed and insert the charging cable 130 into the slot structure when not in use.

[0030] Figure 4 is a schematic diagram of a portable energy storage device charging an electronic device in another embodiment. In this embodiment, the portable energy storage device 110 uses a wireless charging method to charge the electronic device 120, that is, no charging cable is required between the two. At this time, a wireless discharge structure is provided on one side of the portable energy storage device 110, so that it can cooperate with the wireless charging structure on the electronic device 120 to achieve wireless charging of the electronic device 120. In one embodiment, the wireless discharge structure of the portable energy storage device 110 can also serve as a wireless charging structure, thereby receiving radio provided by other energy storage devices to charge itself. In one embodiment, a magnetic structure can also be provided on one side of the wireless discharge structure, so that it can be mutually adsorbed with the magnetic structure on the electronic device 120, thereby strengthening the connection between the electronic device 120 and ensuring that the two can be stably connected during wireless charging, thereby improving the efficiency of wireless charging. It can be understood that the portable energy storage device can also be provided with its functional modules to achieve other functions.

[0031] In scenarios where a portable energy storage device is used to charge an electronic device, or when a portable energy storage device is used to recharge itself, the portable energy storage device typically uses the rated output power to charge the electronic device (this is the discharge process for the portable energy storage device) or uses the rated charging power to charge itself. Using this method for charging and discharging can cause significant damage to the batteries of both the portable energy storage device and the electronic device, and can easily accelerate battery aging, thereby shortening the service life of the electronic device. For example, during the discharge process, the discharge speed of most portable energy storage devices depends on the control of the charging logic of the connected electronic device itself. When the electronic device does not have a corresponding battery maintenance strategy, the portable energy storage device will output the rated charging power, which can easily accelerate the aging of the battery of the electronic device and fail to achieve the purpose of maintaining the battery of the electronic device, that is, it cannot realize the power maintenance function of the electronic device.

[0032] In view of the above problems, an embodiment of the present application provides a charge and discharge control method, which is used to control the charge and discharge process of a portable energy storage device, thereby achieving charging protection for the electronic device or protecting its own charging, thereby reducing the aging rate of the battery and extending the service life of the device, that is, achieving a power conservation function. By controlling the charge and discharge of the portable energy storage device, even if the connected electronic device is not equipped with corresponding charge and discharge protection logic or power conservation function, charging protection can be achieved during the charging process of the electronic device, thereby achieving the purpose of extending the service life of the electronic device.

[0033] The above-mentioned charge and discharge control method can be executed by the control module 114 of the portable energy storage device 110, that is, the portable energy storage device 110 itself is embedded with the charge and discharge control method to control the charging of the connected electronic device. In one embodiment, the above-mentioned charge and discharge control method can also be executed by a terminal device. The terminal device can be an intelligent device that has a communication connection with the portable energy storage device 110 and is provided with an application (APP) or a control component (such as a widget) for charging and discharging management of the portable energy storage device 110. The terminal device can be an electronic device currently connected to the portable energy storage device 110, or it can be other terminal devices independent of the electronic device, as long as it can realize communication and management of the portable energy storage device 110. In other embodiments, the terminal device can also be a server or a central control device to realize control of the portable energy storage device 110.

[0034] FIG5 is a flow chart of a charge and discharge control method according to an embodiment of the present application. As shown in FIG5 , the charge and discharge control method may include the following steps:

[0035] S11, obtaining a first state parameter of an electronic device connected to the portable energy storage device.

[0036] In some embodiments, during the connection process between the portable energy storage device and the electronic device, a first state parameter of the electronic device is obtained. The first state parameter of the electronic device may be obtained by executing the acquisition action after receiving an acquisition instruction. For example, the user may trigger the instruction by using a button on the portable energy storage device or a trigger area of ​​an application on the corresponding terminal device.

[0037] When the charge and discharge control method is executed in the portable energy storage device 110 , the portable energy storage device will acquire the first state parameter at a preset time interval or a preset frequency after receiving the instruction.

[0038] When the charge and discharge control method is executed on a terminal device, the acquisition action is performed by the terminal device, and the acquisition is performed according to a preset time interval or a preset frequency after receiving an instruction triggered by a user.

[0039] The preset time interval or frequency can be set based on actual needs. For example, the preset time interval can be 1 second, 5 seconds, or 10 seconds. It is understood that the preset time interval can also be set to milliseconds to improve sampling accuracy. The specific time interval can be determined based on the control accuracy and update speed to be achieved, and is not limited to the above examples.

[0040] The first state parameter refers to parameter information that reflects the current charging state of the electronic device. For example, the first state parameter may include information such as the temperature, remaining power, charging speed, and time of the electronic device. In this embodiment, in order to distinguish the first state parameter of the electronic device from the second state parameter of the portable energy storage device, under the first state parameter of the electronic device, the temperature of the electronic device is referred to as the first temperature, and the remaining power is referred to as the first remaining power. By obtaining the first state parameter of the electronic device, the current charging state of the electronic device can be known, and then an adjustment basis for the discharge of the portable energy storage device can be provided, ensuring that the output of the portable energy storage device can meet the goal of maintaining the battery of the electronic device, thereby achieving the purpose of increasing the service life of the electronic device.

[0041] S12, generating a corresponding power-saving control instruction according to the first state parameter; the power-saving control instruction is used to control the discharge of the portable energy storage device, thereby charging the electronic device to change the first state parameter of the electronic device.

[0042] In some embodiments, a power-saving control instruction refers to an instruction for controlling the discharge of a portable energy storage device based on a first state parameter of an electronic device. Different first state parameters will generate corresponding discharge control instructions, allowing the portable energy storage device to control discharge according to the power-saving control instruction, thereby charging the electronic device and ultimately achieving a power-saving function. Specifically, when the charge-discharge control method is executed on the portable energy storage device, the control module 114 executes this step and generates a control signal for controlling the DC / DC converter module 112 based on the power-saving control instruction, thereby controlling the output of the input / output module 113 and controlling the charging process of the electronic device, thereby adjusting the first state parameter of the electronic device, ensuring that the first state parameter is within a relatively ideal parameter range, and achieving maintenance of the electronic device. When the charge-discharge control method is executed on a terminal device, the terminal device will send the generated power-saving control instruction to the control module 114 via the wireless communication module 115, causing the control module 114 to perform the corresponding operation according to the power-saving control instruction.

[0043] The power maintenance control instruction can be used to control the discharge of the portable energy storage device, thereby charging the electronic device, thereby changing the first state parameter of the electronic device, so that the electronic device can always be in a better charging state, thereby maintaining the electronic device and extending the service life of the electronic device.

[0044] Taking the example of a first state parameter including a first temperature: when the first temperature of the electronic device is detected, a corresponding power-supply control instruction can be generated according to the first temperature. The power-supply control instruction can control the portable energy storage device to output a discharge current corresponding to the first temperature to charge the electronic device. For example, when the first temperature is higher than a first preset temperature, the first discharge current is output to charge the electronic device, or when the first temperature is higher than a second preset temperature, the second discharge current is output to charge the electronic device. Wherein, the first preset temperature is higher than the second preset temperature, and the first discharge current is smaller than the second discharge current. That is, as the first temperature increases, the discharge current of the portable energy storage device is gradually reduced, thereby achieving the purpose of reducing the first temperature of the electronic device, so that the first temperature of the electronic device is always maintained in a relatively suitable temperature range, and does not cause inconvenience to the user due to excessively high temperature. The charge and discharge control method will be further introduced later in conjunction with specific embodiments.

[0045] In this embodiment, the function of the power conservation control instruction may include but is not limited to controlling the portable energy storage device to adjust the discharge current or discharge power to charge the electronic device, or controlling the portable energy storage device to stop charging the electronic device.

[0046] In some embodiments, there is a correspondence between the power-maintaining control instruction and the first state parameter. By querying the correspondence, the power-maintaining control instruction corresponding to the first state parameter can be obtained. The correspondence can be a function expression, a fitting curve, or a mapping table. That is, after determining the first state parameter, the corresponding power-maintaining control instruction can be determined based on the first state parameter. Different power-maintaining control instructions correspond to different target discharge currents or target discharge powers, thereby controlling the portable energy storage device to ultimately output the target discharge current or target discharge power, charging the electronic device, and ultimately achieving the adjustment of the first state parameter of the electronic device to achieve the purpose of maintaining the battery of the electronic device and extending the service life of the electronic device.

[0047] In some embodiments, obtaining a first state parameter of an electronic device connected to the portable energy storage device includes: obtaining the first state parameter output by the electronic device through wireless communication or wired communication.

[0048] In some embodiments, the portable energy storage device and the electronic device can be connected via wired communication or wireless communication to obtain the first state parameter output by the electronic device via wired communication or wireless communication. When the portable energy storage device and the electronic device are connected via a wired connection, the portable energy storage device and the electronic device can be connected via a charging cable. At this time, in addition to realizing power transmission between the portable energy storage device and the electronic device, the charging cable also performs communication data transmission at the same time, so that the electronic device can transmit its own first state parameter to the portable energy storage device via the charging cable. It can be understood that a dedicated data cable can also be set between the portable energy storage device and the electronic device for communication. Therefore, after a wired connection is established between the portable energy storage device and the electronic device, the first state parameter can be transmitted via wired communication.

[0049] In one embodiment, the portable energy storage device and the electronic device may also be connected via wireless communication. For example, the portable energy storage device and the electronic device are connected via wireless communication methods such as Bluetooth, WiFi, ZigBee, and cellular networks. After a wireless communication connection is established between the portable energy storage device and the electronic device, the first state parameter can be obtained through the wireless communication method. It can be understood that a wireless communication connection is established between the energy storage device and the electronic device, and the two can be a point-to-point direct wireless communication connection, that is, no transfer device is required. The energy storage device and the electronic device may also be wirelessly connected to the electronic device through a server in the cloud. The electronic device sends the first state parameter to the portable energy storage device through the server.

[0050] In the above embodiment, the first state parameter of the electronic device is sampled and obtained by the electronic device itself, and then the portable energy storage device can obtain it through wireless communication or wired communication when needed. Usually, various sensors are provided inside the electronic device to detect its own operating status. Therefore, the sampling data of these sensors can be directly obtained as the first state parameter. For example, when the first state parameter includes the first temperature, the first remaining power and the charging speed of the electronic device, the charging state acquisition component may include a temperature sampling component, a remaining power calculation component and a charging speed sampling component. Among them, the temperature sampling component is used to collect the temperature of the electronic device, the remaining power calculation component is used to calculate the remaining power of the electronic device, and the charging speed sampling component is used to collect the charging speed of the electronic device.

[0051] After communicating with the electronic device, the portable energy storage device may send a request for obtaining the first state parameter to the electronic device, so as to obtain the first state parameter fed back by the electronic device.

[0052] In one embodiment, a corresponding application may be installed in the electronic device, and the relevant first status parameter may be obtained through user authorization of the application.

[0053] In other embodiments, obtaining a first state parameter of an electronic device connected to the portable energy storage device includes determining the first state parameter of the electronic device based on a target sampling parameter of the portable energy storage device. That is, in this embodiment, obtaining the first state parameter of the electronic device may not require establishing a communication connection with the electronic device, thereby ensuring that the portable energy storage device can still implement the charge and discharge control method even if communication between the portable energy storage device and the electronic device is unable to be established.

[0054] Specifically, the portable energy storage device may be provided with corresponding parameter sampling components, such as a temperature sampling component, a discharge current sampling component, and a remaining power calculation component. The second state parameter is obtained by the corresponding parameter sampling component provided in the portable energy storage device, and then the first state parameter of the electronic device is obtained according to the target state parameter in the second state parameter. For example, the first temperature of the electronic device is determined according to the second temperature sampled by the portable energy storage device, the first remaining capacity of the electronic device is determined according to the discharge capacity sampled by the portable energy storage device, and the current charging current and charging speed of the electronic device are determined according to the discharge current of the portable energy storage device.

[0055] In one embodiment, the portable energy storage device is a device with a magnetic attraction function, as shown in FIG4 . The portable energy storage device and the electronic device can be in point or surface contact by magnetic attraction. A temperature sampling component may be provided on the portable energy storage device. The temperature sampling component is arranged on the shell of the side where the magnetic attraction of the portable energy storage device is located, so that the temperature of the electronic device attached to the magnetic attraction surface can be sampled to obtain the second temperature of the portable energy storage device, and then the first temperature of the electronic device can be obtained. Of course, in order to improve the accuracy of temperature sampling, a preset calibration coefficient can also be used to calibrate the sampled second temperature to obtain the first temperature of the electronic device. When there is no actual contact between the portable energy storage device and the electronic device, the first temperature of the electronic device can be calculated based on the charging and discharging time and charging and discharging speed, the second temperature of the portable energy storage device and the ambient temperature.

[0056] In some embodiments, the above-mentioned charge and discharge control method also includes the step of obtaining a second state parameter of the portable energy storage device. The second state parameter refers to parameter information reflecting the current state of the portable energy storage device. For example, the second state parameter may include information such as the second temperature, the second remaining power, the remaining time, and the charge and discharge power of the portable energy storage device. Among them, the remaining time refers to the length of time that the portable energy storage device can provide charging for the electronic device under the current remaining power. The acquisition of the second state parameter of the portable energy storage device can be performed according to a preset sampling frequency or a preset time interval. The preset time interval can be set according to actual needs. For example, the preset time interval can be 1 second, 5 seconds or 10 seconds. It can be understood that in order to improve the sampling accuracy, etc., the preset time interval can also be set to the millisecond level, and it can be set according to specific needs. The specific acquisition of the second state parameter of the portable energy storage device can refer to the above introduction and will not be repeated here.

[0057] After obtaining the second state parameter of the portable energy storage device, step S12 generates a corresponding power-maintaining control instruction according to the first state parameter. Specifically, it includes: generating a corresponding power-maintaining control instruction according to at least one of the first state parameter and the second state parameter; the power-maintaining control instruction is used to control the discharge of the portable energy storage device to change the second state parameter of the portable energy storage device and / or the first state parameter of the electronic device. In this embodiment, the power-maintaining control instruction can generate a power-maintaining control instruction according to at least one of the first state parameter of the electronic device and the second state parameter of the portable energy storage device, thereby changing the second state parameter of the portable energy storage device and / or changing the first state parameter of the electronic device, so that both the electronic device and the portable energy storage device can be in a better state, realizing power-maintaining processing of the electronic device and the portable energy storage device, and extending the service life of the electronic device and the portable energy storage device.

[0058] Specifically, in the above-mentioned charge and discharge control method, the second state parameter of the portable energy storage device and the first state parameter of the electronic device can be obtained at the same time, so as to generate a corresponding power maintenance control instruction in combination with the first state parameter and the second state parameter, so that the portable energy storage device can be charged and discharged by the power maintenance control instruction, thereby changing the second state parameter of the portable energy storage device and the first state parameter of the electronic device, so that the batteries of both can be maintained and reach the optimal usage state, which can realize the maintenance of the portable energy storage device itself and the battery of the electronic device, and extend the service life of the portable energy storage device and the electronic device.

[0059] It is understood that when generating power-maintenance control instructions, the state parameters of the device currently requiring maintenance may also be used. For example, when a first state parameter of an electronic device exceeds a desired operating state, a corresponding power-maintenance control instruction is generated based on this first state parameter to control the discharge of the portable energy storage device, thereby adjusting the first state parameter of the electronic device to the desired operating state. Typically, the desired operating state refers to an operating state set by the user or preset by the device, in which performance degradation of the device is minimized. For another example, when a second state parameter of a portable energy storage device exceeds a desired operating state, a corresponding power-maintenance control instruction is generated based on the second state parameter to control the charging and discharging of the portable energy storage device, thereby adjusting the second operating state of the portable energy storage device to the desired operating state. The desired operating state of the electronic device and the desired operating state of the portable energy storage device can be specifically set based on their respective product performance requirements and may or may not be the same. The above-described charge and discharge control method allows for simultaneous battery maintenance of both the electronic device and the portable energy storage device.

[0060] In some embodiments, when the first state parameter includes at least one of a first temperature and a first remaining power, generating a corresponding power conservation control instruction according to the first state parameter includes at least one of the following:

[0061] First, when the first temperature is not within the preset operating temperature range of the electronic device, outputting a first power conservation control instruction; the first power conservation control instruction is used to control the portable energy storage device to reduce the discharge speed to charge the electronic device until the first temperature of the electronic device is within the preset operating temperature range;

[0062] Second, when the first remaining power is greater than the first power threshold, outputting a second power conservation control instruction, the second power conservation control instruction being used to control the portable energy storage device to reduce the discharge speed to charge the electronic device until the electronic device is charged to the target power;

[0063] Third, when the first remaining power is less than the second power threshold, output a third power conservation control instruction, the third power conservation control instruction being used to control the portable energy storage device to reduce the discharge speed to charge the electronic device until the first remaining power of the electronic device is greater than or equal to the second power threshold;

[0064] Fourth, when the first remaining power is greater than or equal to the target power, the portable energy storage device is controlled to stop charging the electronic device.

[0065] The following describes the above four situations respectively.

[0066] In some embodiments, in the above-mentioned charge and discharge control method, generating a corresponding power-saving control instruction based on the first state parameter includes: outputting a first power-saving control instruction when the first temperature is not within the preset operating temperature range of the electronic device; the first power-saving control instruction is used to control the portable energy storage device to reduce the discharge speed to charge the electronic device until the first temperature of the electronic device is within the preset operating temperature range. The preset operating temperature range refers to a preset temperature range corresponding to when the electronic device is in an optimal charging state. For example, the preset operating temperature range can be 0°C-35°C. In this embodiment, reducing the discharge speed of the portable energy storage device can include reducing at least one of the discharge current, discharge power, and discharge rate. Generally, under the premise that the output voltage remains unchanged, there is a positive correlation between the discharge current and the discharge power. Therefore, in this embodiment, discharge control can be achieved by reducing the discharge current, or by reducing the discharge power, and both have equivalent control results. When the first temperature of the electronic device is not within the preset operating temperature range of the electronic device (for example, the first temperature is lower than 0°C, or the first temperature is higher than 35°C), the portable energy storage device is controlled to reduce the discharge speed to charge the electronic device until the first temperature of the electronic device is within the preset operating temperature range, and then the portable energy storage device is controlled to charge the electronic device with the rated discharge current or the discharge current requested by the electronic device. This can avoid the problem of heat damage to the battery of the electronic device caused by the portable energy storage device charging the electronic device with a large current or high power when the temperature of the electronic device is too high or too low, thereby enabling the battery of the electronic device to operate in the battery cell comfort zone for a long time, ensuring that the normal use of the electronic device will not be affected by excessive temperature, and extending the battery life.

[0067] Specifically, when the first temperature exceeds the preset operating temperature range, that is, when the first temperature is too high, the discharge parameters (such as discharge power) can be gradually reduced according to the temperature range of the first temperature. The parameter adjustment process still needs to take into account the requirement of minimizing the charging time, thereby achieving fast charging of electronic devices while ensuring that the temperature rise of the battery caused by charging is reduced. For example, temperatures above 35°C can be divided into different intervals, each corresponding to a different discharge power. The higher the temperature, the smaller the corresponding discharge power, and the discharge power decreases step by step as the temperature increases.

[0068] In some embodiments, in the above-mentioned charge and discharge control method, generating a corresponding power conservation control instruction based on the first state parameter includes: when the first remaining power is greater than the first power threshold, outputting a second power conservation control instruction, the second power conservation control instruction being used to control the portable energy storage device to reduce the discharge speed to charge the electronic device until the electronic device is charged to a target power. The first power threshold can be used to indicate that the current electronic device is in a state close to full charge. The first power threshold can be set to a value of 95%, 97%, 99%, etc., so that when it is detected that the first remaining power of the electronic device is greater than the first power threshold, it can be confirmed that the electronic device is close to full charge. At this time, the discharge speed of the portable energy storage device is reduced, such as reducing the discharge current, so that when the electronic device is close to full charge, it is charged with a low current or low power until the electronic device is fully charged, thereby achieving battery maintenance for the electronic device and extending the service life of the electronic device.

[0069] In some embodiments, the charge-discharge control method described above generates a corresponding power-saving control instruction based on the first state parameter, including: when the first remaining power is less than a second power threshold, outputting a third power-saving control instruction, the third power-saving control instruction being used to control the portable energy storage device to reduce the discharge rate to charge the electronic device until the first remaining power of the electronic device is greater than or equal to the second power threshold. The second power threshold is a preset minimum remaining power for the electronic device to be in an optimal charging state. If the remaining power is below the second power threshold, the electronic device is considered to be in a low power state. For example, the second power threshold may be 10%. When the first remaining power of the electronic device is less than the second power threshold, the portable energy storage device is controlled to reduce the discharge rate, such as by reducing the discharge current, to charge the electronic device until the first remaining power of the electronic device is greater than or equal to the second power threshold, that is, until the electronic device exits the low power state. In the above embodiment, when the first remaining power of the electronic device is low, the portable energy storage device charges the electronic device by reducing the discharge rate, such as by reducing the discharge current, to slowly charge the electronic device to the second power threshold at a low charging rate, thereby avoiding damage to the battery caused by rapid charging when the battery is in a low power state and extending the battery life.

[0070] In one embodiment, in the above-mentioned charge and discharge control method, generating a corresponding power conservation control instruction based on the first state parameter includes: controlling the portable energy storage device to stop charging the electronic device when the first remaining power is greater than or equal to the target power. The target power can be set according to actual needs. For example, the target power can be the remaining power when fully charged, that is, 100%. The target power can also be customized by the user, such as setting it to 80% or other remaining power values. Taking the user setting the target power to 80% as an example, when it is detected that the first remaining power of the electronic device reaches 80%, the portable energy storage device is controlled to stop charging the electronic device, so that the first remaining power of the electronic device can be maintained below 80%. This can avoid damage to the battery caused by the electronic device being in a fully charged or overcharged state for a long time, and can extend the battery life of the electronic device. In one embodiment, the portable energy storage device can be provided with corresponding adjustment buttons or a touch screen for configuration. In other embodiments, the target power of the electronic device can also be configured through an application on the terminal device.

[0071] In some embodiments, the portable energy storage device has multiple discharge modes, and different discharge modes have different discharge control strategies. For example, the discharge mode includes at least one of a power conservation mode, a custom mode, and a normal mode.

[0072] At this time, the above-mentioned charge and discharge control method further includes at least one of the following:

[0073] First, when the portable energy storage device is in the power conservation mode, executing the step of generating a corresponding power conservation control instruction according to the first state parameter;

[0074] Second, when the portable energy storage device is in a customized mode, a corresponding discharge control signal is generated according to the user-defined discharge preference configuration information to control the portable energy storage device to discharge so as to charge the electronic device;

[0075] Third, when the portable energy storage device is in normal mode, a discharge control instruction is generated; the discharge control instruction is used to control the portable energy storage device to output a DC current with preset parameters to charge the electronic device.

[0076] The above-mentioned charge and discharge control method can expand the application scenarios of portable energy storage devices to meet the charging needs of users in different application scenarios by configuring multiple discharge modes for the portable energy storage device and performing discharge processing according to different discharge modes to charge electronic devices.

[0077] Specifically, the power conservation mode may refer to a mode that maintains the battery by limiting the charging state of the electronic device, thereby extending the battery life. That is, only when the portable energy storage device is in the power conservation mode is S12 executed, that is, the step of generating the corresponding power conservation control instruction according to the first state parameter is executed. In other embodiments, the power conservation mode may also be a mode that maintains the battery by limiting the charging state of the electronic device and the discharging state of the portable energy storage device, thereby extending the battery life. That is, only when the portable energy storage device is in the power conservation mode is the step of generating the corresponding power conservation control instruction according to the first state parameter and the second state parameter executed. It can be understood that in the power conservation mode, the discharge of the portable energy storage device will be controlled according to the state parameters of the electronic device and / or the portable energy storage device, thereby ensuring that the state of the electronic device and / or the portable energy storage device is always in an optimal operating state, thereby maintaining the battery of the electronic device and / or the portable energy storage device and realizing the power conservation function.

[0078] Custom mode refers to a mode in which the user customizes the discharge preference configuration information. The discharge preference configuration information may include the upper limit of the remaining power of the electronic device for each charge (also known as the upper limit of the state of charge (SOC)), the start time and / or end time of each charge of the electronic device, the charging power when the electronic device is charging, etc. In the custom mode, the user can also configure different discharge strategies for different time periods to charge the electronic device. In one embodiment, in addition to customizing the charging of the electronic device, the custom mode can also customize the charging and discharging of the portable energy storage device, such as setting the upper and lower limits of the remaining power of the portable energy storage device, stopping charging when the set upper limit of the remaining power is reached, and stopping discharging when the set lower limit of the remaining power is reached. By providing a custom mode, the user can perform personalized configuration to meet the personalized usage needs of the user in different time periods or different users.

[0079] In some embodiments, when the portable energy storage device is in normal mode, the portable energy storage device is controlled to output direct current with preset parameters to charge the electronic device. The preset parameters may be a preset current or a preset power. Wherein, when a communication connection is established between the portable energy storage device and the electronic device, and the portable energy storage device supports the fast charging protocol of the electronic device, the preset parameters may be parameters agreed upon in the fast charging protocol. For example, if the fast charging protocol of the electronic device supports a charging power of 30W, the portable energy storage device outputs 30W of direct current to charge the electronic device, thereby achieving fast charging of the electronic device. When the portable energy storage device does not support the fast charging protocol of the electronic device, the preset parameters may be the rated discharge parameters of the portable energy storage device, such as directly outputting according to the rated output power of the portable energy storage device, thereby greatly meeting the fast charging needs of different electronic devices.

[0080] In one embodiment, the various modes of the portable energy storage device can be triggered to enter the corresponding discharge mode when the corresponding state parameters of the electronic device or the portable energy storage device meet the corresponding conditions. Of course, the switching control of the discharge mode of the portable energy storage device can also be achieved through manual operation by the user. For example, a mode switching button is provided on the portable energy storage device, or a mode switching area is configured through an application on the terminal device, so that the user can choose to enter the corresponding mode as needed. In other words, if a user's customized configuration is received, the custom mode is entered by default; when the user controls the power conservation mode switching button, the power conservation mode is entered, otherwise the normal mode is entered.

[0081] In some embodiments, entering or exiting the power conservation mode may be performed using the following steps: when the first state parameter meets the preset power conservation condition, controlling the portable energy storage device to enter the power conservation mode; or receiving a mode switching instruction input by the user, and controlling the portable energy storage device to enter or exit the power conservation mode according to the mode switching instruction. For example, when it is detected that the temperature of the electronic device exceeds a preset temperature threshold, the portable energy storage device is triggered to enter the power conservation mode, and when it is detected that the temperature of the electronic device is within the temperature range of the expected operating state, the power conservation mode is exited. Alternatively, after receiving the user's mode switching instruction, the portable energy storage device enters the power conservation mode, and the power conservation mode is exited only when the mode switching instruction is received again. For example, the user can control the portable energy storage device to exit the power conservation mode by triggering a physical button on the portable energy storage device, thereby restoring it to normal mode, so as to charge the mobile phone to 100% as quickly as possible.

[0082] The above method controls the portable energy storage device to enter a power conservation mode when the first state parameter meets a preset power conservation condition, automatically enabling the power conservation mode. This allows for timely adjustment of the charging state of the electronic device or the discharge state of the portable energy storage device, thereby improving battery life. The above method controls the portable energy storage device to enter a power conservation mode upon receiving a mode switching command input by the user, thereby meeting the user's power conservation needs for the electronic device and / or portable energy storage device.

[0083] In some embodiments, the preset power conservation conditions can be set based on actual needs. As described above, the preset power conservation conditions may include: the first temperature of the electronic device is not within the preset operating temperature range of the electronic device, the first remaining power is greater than a first power threshold, the first remaining power is less than a second power threshold, and the first remaining power is greater than or equal to a target power.

[0084] In some embodiments, the electronic device and / or the portable energy storage device can perform human-computer interaction, including but not limited to keyboard, mouse, remote control, touchpad, or voice-controlled device. Through the above-mentioned interaction methods, the user causes the electronic device to send a mode switching instruction to the portable energy storage device through the server, or directly send the mode switching instruction to the portable energy storage device, or the portable energy storage device directly receives the mode switching instruction input by the user.

[0085] In some embodiments, the above-mentioned charge and discharge control method further includes: displaying a mode identifier corresponding to the current mode of the portable energy storage device. Different discharge modes may correspond to different mode identifiers, so that the user can know the current mode of the portable energy storage device based on the displayed mode identifier. Specifically, the portable energy storage device may be provided with a display screen, which can display the mode identifier of the current mode, so that the user can query the status when the display screen of the portable energy storage device is turned on. In one embodiment, the mode identifier can also be displayed on the display screen of the electronic device, so that the user can also know the current status of the portable energy storage device through the connected electronic device. In another embodiment, the corresponding display can also be displayed on the display screen of the terminal device that communicates with the portable energy storage device, such as a pop-up window display or display in the corresponding application, or display through a desktop component.

[0086] In one embodiment, the above-mentioned charge and discharge control method further includes: when the portable energy storage device is in the power conservation mode, outputting a preset prompt information; the preset prompt information is used to prompt the user that the portable energy storage device is adjusting the first state parameter of the electronic device to protect the battery life of the electronic device. In the power conservation mode, the portable energy storage device does not always perform fast charging at maximum power, but controls the discharge of the portable energy storage device according to the first state parameter of the electronic device, thereby improving the first state parameter of the electronic device. Therefore, during the execution of the power conservation strategy, the user can be informed by outputting the preset prompt information that the current portable energy storage device is adjusting the first state parameter of the electronic device based on the power conservation strategy, thereby ensuring that the user can perceive the operation. The preset prompt information can be displayed in the same manner as the aforementioned mode identifier, or can be output through voice, etc., to prompt the user.

[0087] In some embodiments, when the first state parameter includes a first temperature and a charging speed, the charge-discharge control method further includes: generating a heating instruction when the first temperature is within a preset low temperature range. The heating instruction is used to control a processor of the electronic device to enter a high-frequency operation state, or to control a preset heating device to perform heating so that the first temperature of the electronic device is above the preset low temperature range.

[0088] The preset low temperature range refers to the temperature range within which the charging speed of the electronic device will be affected and slowed, that is, the temperature at which the battery activity is low. For example, the preset low temperature range can be (-10℃ to 5℃). In other embodiments, the preset low temperature range can also be set to below 0℃. When the first temperature of the electronic device is within the preset low temperature range, it can be determined that the electronic device is currently in a state requiring heating. In another embodiment, in addition to considering the preset low temperature range, the current charging speed of the electronic device is also considered. Only when the first temperature is within the preset low temperature range and the charging speed is less than a preset speed threshold is it confirmed that it is in a state requiring heating and a heating instruction is generated. Typically, when an electronic device is in a low temperature environment, it is necessary to heat its battery to enter a fast charging state. Therefore, if it is detected that the current charging speed of the electronic device is greater than the preset speed threshold, it can be confirmed that the current charging speed of the electronic device has entered a state where fast charging is possible. The heat released by the charging itself can achieve the purpose of heating the battery cell to maintain battery activity, and there is no need to control the electronic device to perform additional heating operations. In one embodiment, the preset speed threshold can be a preset charging power threshold, which can be 5W.

[0089] In one embodiment, when it is detected that the first temperature is within a preset low temperature range and the charging speed is less than a preset speed threshold, the portable energy storage device can be controlled to enter a corresponding extreme cold mode. That is, the discharge mode of the portable energy storage device also includes the extreme cold mode. When it is detected that the first state parameter has exceeded the aforementioned trigger condition, the extreme cold mode is exited.

[0090] The above-mentioned charge and discharge control method heats an electronic device whose first temperature is within a preset low temperature range and whose charging speed is less than a preset speed threshold. This method can activate the battery of the electronic device in a low-temperature environment, thereby increasing the battery activity of the electronic device and thereby increasing the charging rate of the electronic device, enabling it to quickly enter a fast-charging state. During the charging process, the temperature of the electronic device is always maintained between 0 and 35°C, thereby achieving the purpose of maintaining battery life. The specific temperature range can be set according to the environment and device performance, and is not limited to the above-mentioned embodiment.

[0091] In some embodiments, when the first temperature is in a preset low temperature range and the charging speed is less than a preset speed threshold, it indicates that the battery activity of the electronic device is low and the electronic device needs to be heated so that the heating is exited when the first temperature is higher than the preset low temperature range or the charging speed is greater than or equal to the preset speed threshold, that is, the sending of the heating instruction is stopped. In one embodiment, a stop heating instruction can also be generated to control the corresponding device to exit heating. When the charge and discharge control method is executed by a portable energy storage device, it can be sent by the portable energy storage device to the electronic device through wired communication or wireless communication. When the charge and discharge control method is executed by a terminal device, the application in the terminal device sends the heating instruction to control the electronic device to heat.

[0092] In some embodiments, a heating instruction is used to control a processor of an electronic device, such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), to enter a high-frequency operating state, causing the processor to execute related instructions at a higher frequency, increasing the power consumption and heat of the electronic device, thereby generating heat to maintain or improve battery activity. If the electronic device does not receive the heating instruction or receives a stop heating instruction, it will exit the high-frequency operating state and control the processor frequency according to a preset operating strategy.

[0093] In other embodiments, the heating instruction is used to control a preset heating device to heat the electronic device so that the first temperature of the electronic device is higher than a preset low temperature range. For example, a preset heating device (e.g., a heating layer) is provided on the portable energy storage device, and when the portable energy storage device is in contact with the electronic device, the electronic device is directly heated by the heating layer. For another example, a preset heating device is provided on the electronic device, and the heating instruction is used to control the preset heating device to start to heat the electronic device.

[0094] In some embodiments, the charge-discharge control method further includes the step of obtaining the electronic device's schedule information, currently running program information, and user charging habit information. In this case, generating a corresponding power-maintenance control instruction based on the first state parameter includes generating the power-maintenance control instruction based on at least one of the first state parameter, schedule information, currently running program information, and user charging habit information. The method can generate the power-maintenance control instruction based on the electronic device's first state parameter, schedule information, currently running program information, and user charging habit information, thereby controlling the charging of the electronic device based on more comprehensive state parameters, thereby achieving the purpose of maintaining the electronic device's battery and meeting the user's power usage needs.

[0095] Schedule information, information about currently running programs, and user charging habits can all be obtained with user authorization. Schedule information includes information such as outing times and meeting schedules. For example, if a user sets a schedule of a morning meeting from 9:00 AM to 10:00 AM on Monday, the corresponding power conservation control instruction is used to control the portable energy storage device to charge the electronic device to a full charge state, i.e., 100%, before 9:00 AM, thereby facilitating user use. For another example, if a user sets a schedule of going out at 3:00 PM, the portable energy storage device can be controlled to charge the electronic device to a full charge state before 3:00 PM, regardless of the first upper limit of the remaining power, to meet the user's usage needs. Furthermore, by obtaining schedule information, the charge and discharge speed can be adjusted based on the current actual remaining charging time and the actual charging time required by the electronic device. For example, a slower charging speed can be used in the early stages of charging, and a fast charge can be used later to fully charge the electronic device. This can prevent the electronic device from being fully charged or overcharged for a long time due to prolonged charging, thereby maintaining the battery of the electronic device and extending its service life.

[0096] In some embodiments, information about the electronic device's currently running programs can also be obtained. The type and number of applications running on the electronic device can cause the electronic device to generate additional operating heat in addition to the heat generated by charging. Therefore, when using a portable energy storage device to charge an electronic device, the current applications running on the electronic device can be fully considered. For example, when the electronic device is currently running a heavy-loaded application such as navigation, camera, or video chat, a high level of heat will be generated. In this case, a corresponding power supply control instruction can be generated based on the first state parameter and the current program information of the electronic device to output a power supply that matches the current state to charge the electronic device. Specifically, when the first remaining power of the electronic device is greater than a third power threshold, the portable energy storage device is controlled to output a minimum output power to charge the electronic device. This minimum output power is greater than the current power consumption of the electronic device, thereby ensuring that the electronic device is charged at the minimum power while ensuring that the power of the electronic device does not decrease, thereby preventing the temperature of the electronic device from rising too high and affecting its use. The third power threshold can be set according to actual needs, for example, the third power threshold is 70%. Specifically, based on the current application running status of the electronic device and the power outage situation in the past period of time, the minimum power required per unit time to support the operation of power-consuming devices such as the screen and system-on-chip (SoC) of the electronic device can be fed back and calculated, thereby controlling the portable energy storage device to charge the electronic device with this minimum power.

[0097] As another example, when the first remaining power of the electronic device is less than or equal to 70%, the predicted charging time is obtained based on the first remaining power of the electronic device, and the appropriate discharge power is determined based on the predicted rechargeable time and the temperature rise rate corresponding to different charging powers to charge the electronic device, thereby meeting the charging needs of the electronic device and not causing the temperature of the electronic device to rise too high, thereby ensuring the normal use of the electronic device. For example, the charging power with the fastest charging time can be selected based on the current application running status of the electronic device, the power outage and heat generation conditions in the past period of time, and the comprehensive heat generation conditions. For example, if charging directly with 20W generates more heat, it may drop to 5W or even lower after charging for 5 minutes, while charging with 15W can sustain the heat generation for 10 minutes or even longer, thereby shortening the charging time of the mobile phone.

[0098] User charging habit information may include the user's living time, such as the user's sleeping time and the user's waking time, the first remaining power of the electronic device when the user stops charging each time, the user's usual power usage time and charging speed, etc. Therefore, a power conservation control instruction can be generated based on the user's power usage habits and other relevant factors. For example, if the first remaining power of the electronic device is greater than a fourth power threshold (for example, the fourth power threshold is 80%), and the current time is less than 1 hour from the user's sleeping time or the current time is later than the preset time, the portable energy storage device is controlled to stop charging the electronic device. For another example, in a scenario where another energy storage device is used to charge the portable energy storage device and the portable energy storage device is charging the electronic device, that is, when the portable energy storage device is in a scenario where it is charging and discharging at the same time, if the current time is greater than 2 hours from the user's waking time, the portable energy storage device is controlled to stop charging the electronic device; if the current time is less than 2 hours from the user's waking time, the portable energy storage device is controlled to charge the electronic device until the electronic device is charged to the target power (for example, 100%).

[0099] In one embodiment, the above-mentioned charging and discharging control method further includes the following steps: determining the operating power of the electronic device based on the current operating program information of the electronic device; generating a power supply control instruction based on the operating power; and the power supply control instruction is used to control the portable energy storage device to output a power supply power greater than the operating power to power the electronic device.

[0100] Usually, many users have the habit of using their mobile phones while charging. In this embodiment, the above method can be used to ensure that the electronic device gives priority to the power supply of the portable energy storage device during the process of charging and using. That is, the portable energy storage device must support the power required for the operation of the electronic device, that is, the above-mentioned operating power, while charging the electronic device, thereby achieving battery maintenance for the electronic device and extending the service life of the battery. Specifically, the operating power required for the operation of the electronic device is first determined based on the current operating program information of the electronic device. Usually, the operating power can be determined based on historical data, or based on the current sampling value during the operation of the application. After determining the operating power, the portable energy storage device is controlled to provide the electronic device with a power supply greater than the operating quantity, thereby ensuring that the power supply of the portable energy storage device can meet the operating power requirements of each application of the electronic device and the requirement that the electronic device does not lose power and gradually replenishes power during charging.

[0101] In one embodiment, the charging state of the portable energy storage device can also be controlled based on its charging state parameters. Therefore, the above-mentioned charge and discharge control method further includes: obtaining the charging state parameters of the portable energy storage device when the portable energy storage device is connected to a charger; generating a charging request instruction based on the charging state parameters; the charging request instruction is used to request the charger to output a charging current corresponding to the charging state parameters to charge the portable energy storage device, thereby adjusting the charging state parameters of the portable energy storage device.

[0102] When it is detected that the portable energy storage device is connected to the charger, it can be confirmed that the portable energy storage device is currently in a charging state, or at least in a state where it can be charged. At this time, the charging state parameters of the portable energy storage device, such as the charging current, the second temperature, etc., are obtained, and a corresponding charging request instruction is generated based on the charging state parameters. The charging request instruction is used to request the charger to output a charging current corresponding to the charging state parameters to charge the portable energy storage device, thereby adjusting the charging state parameters of the portable energy storage device to achieve the purpose of charging and maintaining the portable energy storage device and extending the battery life of the portable energy storage device.

[0103] In one embodiment, the charging status parameter may include a second temperature. When it is detected that the second temperature exceeds the corresponding temperature preset value, a charging request instruction to reduce the charging current may be generated, so that the charger charges the portable energy storage device with a smaller charging current. For another example, the charging status parameter includes a second remaining power. When the second remaining power of the portable energy storage device is greater than the target power, the charging request instruction is stopped from being sent, so that the charger stops charging the portable energy storage device. In other embodiments, the DC / DC conversion module in the portable energy storage device may also be controlled according to the charging status parameter of the portable energy storage device, so as to realize charging control of the portable energy storage device, and then adjust the charging status parameter of the portable energy storage device so that it is in a better operating state, thereby extending the life of the battery.

[0104] In one embodiment, when the portable energy storage device is connected to a charger, the following steps may also be included:

[0105] Controlling the portable energy storage device to charge at a first charging speed until a second remaining power of the portable energy storage device reaches a first charging threshold;

[0106] Obtain the remaining charging time, remaining charge capacity and current charging power of the portable energy storage device;

[0107] When the product of the remaining charging time and the current charging power is greater than the remaining chargeable amount, the portable energy storage device is controlled to stop charging until the product of the current remaining charging time and the current charging power is less than or equal to the remaining chargeable amount.

[0108] When a portable energy storage device is connected to a charger for charging, it will first be charged at a first charging speed. The first charging speed can be a target charging speed determined based on parameters such as the current power level and temperature of the portable energy storage device, or it can be the rated charging speed of the portable energy storage device. In other words, during the initial charging of the portable energy storage device, its charging speed will not be restricted until the second remaining power of the portable energy storage device reaches a first charging threshold. The first charging threshold can be set by the user based on personal preference or by default by the system. For example, the first charging threshold can be set to 80%.

[0109] After the second remaining power of the portable energy storage device reaches the first charging threshold, the remaining rechargeable time, remaining rechargeable capacity and current charging power of the portable energy storage device will be obtained. The remaining rechargeable time can be obtained based on the statistics of the user's power usage habits in historical data, such as counting the time periods when the user charges every day, and then setting the time periods with a cumulative charging probability higher than a certain threshold as rechargeable time periods, and then determining the remaining rechargeable time based on the relationship between the current time and the rechargeable time period. The remaining rechargeable capacity is the total rechargeable capacity of the portable energy storage device minus the current remaining power, that is, the second remaining power. In one embodiment, the total rechargeable capacity can be the rated capacity, or it can be the actual total rechargeable capacity after correction based on the battery health status. The current charging power can be obtained based on the sampled data.

[0110] When the product of the remaining chargeable time and the current charging power is greater than the remaining chargeable capacity, it means that when charging at the current charging power, the portable energy storage device will be in a slow charging state for a long time after being fully charged. Therefore, when it is detected that the second remaining capacity of the portable energy storage device reaches the first charging threshold, and the calculated product of the remaining chargeable time and the current charging power is greater than the remaining chargeable capacity, charging of the portable energy storage device is stopped to avoid the portable energy storage device being in a slow charging state for a long time. Of course, charging is resumed when the product of the current remaining chargeable time and the current charging power is less than or equal to the remaining chargeable capacity to ensure that the portable energy storage device is fully charged within the rechargeable time period.

In some embodiments, the charge and discharge control device 20 may include multiple functional modules composed of computer program segments. The computer program for each program segment in the charge and discharge control device 20 can be stored in the memory of an electronic device and executed by at least one processor to perform the charge and discharge control functions (see Figure 5 for details).
