[0018] In order to more clearly understand the above-mentioned purposes, 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 in the embodiments can be combined with each other without conflict.

[0019] 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.

[0020] 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 belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0021] With the popularity of various mobile electronic devices, such as the increase in electronic devices such as mobile phones and tablets, the demand for charging electronic devices has also increased, so it is becoming more and more important to use batteries to charge electronic devices. Especially when outdoors, in order to avoid power shortage of electronic devices, users usually carry portable energy storage devices such as power banks. In addition to power banks, portable energy storage devices that can charge electronic devices can also be portable energy storage devices such as mobile power supplies (also known as outdoor power supplies). Usually, power banks are small-capacity energy storage devices, and their capacity units are usually milliampere hours (mAh); and the capacity of mobile power supplies is relatively larger than that of power banks, and their capacity units are usually watt-hours (Wh). However, with the development of large-capacity power banks and the abundance of small-capacity mobile power products, there are also some power banks whose capacity is close to or even greater than that of some mobile power supplies.

[0022] 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, and can also be used in mobile energy storage equipment, household energy storage equipment and other energy storage equipment, 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.

[0023] Figure 1 FIG. 1 is a schematic diagram of a portable energy storage device 110 in an embodiment. Figure 1The portable energy storage device 110 includes a housing (not shown in the figure), a battery module 111, a DC / DC conversion module 112, an input / output module 113 and a control module 114. Among them, the battery module 111 includes a battery 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 group and to protect the battery from over-temperature, low temperature, overvoltage, overcurrent, undervoltage and the like. The battery group may include a single battery cell or two or more batteries. The number of batteries is determined specifically according to 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 a device such as an electronic device that needs to be charged, or it can be connected to a power supply device that can charge the portable energy storage device, such as a charger or other energy storage device. 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 to charge the battery module 111. 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 / output 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.

[0024] In another embodiment, if Figure 2 As shown, the portable energy storage device 110 may also include a wireless communication module 115. The wireless communication module 115 can communicate with other devices with wireless communication functions after wireless connection. For example, the portable energy storage device 110 can wirelessly communicate with the connected electronic device through the wireless communication module 115, so as to obtain the 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 pure dry device 110 is installed in the electronic device or other unconnected electronic device, the portable energy storage device 110 can 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.

[0025] 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. Other communication modules may also be provided in the portable energy storage device 110 as required, which is not limited here.

[0026] Figure 3 An example diagram of charging an electronic device using a portable energy storage device. Figure 3 , the portable energy storage device 110 can be connected to an electronic device 120 such as a mobile phone through a charging cable 130, so that the portable energy storage device 110 charges the electronic device 120. At this time, a corresponding discharge interface needs to be provided on the portable energy storage device 110, such as a Type C interface, a Type A interface, and a Lighting interface. One or more discharge interfaces can be provided 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, a slot structure can also be provided on the portable energy storage device 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 needed.

[0027] Figure 4 Schematic diagram of charging of an electronic device by a portable energy storage device in another embodiment. In this embodiment, the portable energy storage device 110 uses wireless charging to charge the electronic device 120, that is, no charging cable is needed between the two at this time. 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, thereby realizing wireless charging of the electronic device 120. In one embodiment, the wireless discharge structure of the portable energy storage device 110 can also be used as a wireless charging structure, so as to receive the radio provided by other energy storage devices to charge itself. In one embodiment, a magnetic suction structure can also be provided on one side of the wireless discharge structure, so as to mutually adsorb with the magnetic suction structure on the electronic device 120, thereby strengthening the connection with the electronic device 120, ensuring that the two can be stably connected during the wireless charging process, and improving the wireless charging efficiency. It can be understood that the portable energy storage device can also be provided with its functional modules to realize other functions.

[0028] In scenarios where a portable energy storage device is used to charge an electronic device, or a portable energy storage device is used to charge itself, the portable energy storage device usually uses the rated output power to charge the electronic device (a discharge process for the portable energy storage device) or uses the rated charging power to charge itself. Charging and discharging in this way will cause great 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 of most portable energy storage devices, the discharge speed 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 battery aging 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.

[0029] In view of the above problems, an embodiment of the present application provides a charging and discharging control method, which is used to control the charging and discharging process of a portable energy storage device, thereby realizing charging protection for the electronic device or achieving self-charging protection, thereby reducing the battery aging rate and extending the service life of the device, that is, realizing the power conservation function. By controlling the charging and discharging of the portable energy storage device, even if the connected electronic device is not equipped with the corresponding charging and discharging protection logic or power conservation function, charging protection can be realized during the charging process of the electronic device, thereby achieving the purpose of extending the service life of the electronic device.

[0030] 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.

[0031] Figure 5 is a flow chart of the charge and discharge control method provided in the embodiment of the present application, such as Figure 5 As shown, the charge and discharge control method may include the following steps:

[0032] S11, obtaining a first state parameter of an electronic device connected to the portable energy storage device.

[0033] In some embodiments, during the connection process between the portable energy storage device and the electronic device, the first state parameter of the electronic device is obtained. The acquisition of the first state parameter of the electronic device may be performed after receiving the acquisition instruction. For example, the user may trigger the instruction through a button on the portable energy storage device or a trigger area of ​​an application on the corresponding terminal device.

[0034] 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.

[0035] When the charge and discharge control method is executed in a terminal device, the acquisition action is executed by the terminal device, and the acquisition is performed according to a preset time de-rating or a preset frequency after receiving an instruction triggered by a user.

[0036] The preset time interval or preset frequency can be set according to actual needs. For example, the preset time interval can be 1 second, 5 seconds or 10 seconds. It is understood that in order to improve the sampling accuracy, etc., the preset time interval can also be set to the millisecond level. It can be determined specifically according to the control accuracy and update speed to be achieved, and is not limited to the above examples.

[0037] 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, thereby providing an adjustment basis for the discharge of the portable energy storage device, 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.

[0038] S12, generating a corresponding power conservation control instruction according to the first state parameter; the power conservation 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.

[0039] In some embodiments, the power maintenance control instruction refers to an instruction for controlling the discharge of the portable energy storage device according to the first state parameter of the electronic device. Different first state parameters will generate corresponding discharge control instructions, so that the portable energy storage device can control the discharge according to the power maintenance control instruction, and then charge the electronic device, and finally realize the power maintenance function. Specifically, when the charging and discharging 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 conversion module 112 according to the power maintenance control instruction, thereby realizing the output control of the input / output module 113, and then realizing the control of the charging process of the electronic device, thereby realizing the adjustment of the first state parameter of the electronic device, ensuring that its first state parameter can be within a relatively ideal parameter range, and realizing the maintenance of the electronic device. When the charging and discharging control method is executed on the terminal device, the terminal device will send the generated power maintenance control instruction to the control module 114 through the wireless communication module 115, so that the control module 114 performs the corresponding operation according to the power maintenance control instruction.

[0040] 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.

[0041] Take the example that the first state parameter includes the 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, such as when the first temperature is higher than the first preset temperature, output the first discharge current to charge the electronic device, or when the first temperature is higher than the second preset temperature, output the second discharge current to charge the electronic device. Among them, the first preset temperature is higher than the second preset temperature, and the first discharge current is less than the second discharge current, that is, as the first temperature increases, the discharge current of the portable energy storage device is gradually reduced, so as to achieve 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 more suitable temperature range, and will not cause inconvenience to the user due to excessively high temperature. The charging and discharging control method will be further introduced in conjunction with specific embodiments later.

[0042] 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.

[0043] In some embodiments, there is a corresponding relationship between the power maintenance control instruction and the first state parameter. By querying the corresponding relationship, the power maintenance control instruction corresponding to the first state parameter can be obtained. The corresponding relationship can be a function expression, a fitting curve, or a mapping table. That is, after determining the first state parameter, the corresponding power maintenance control instruction can be determined according to the first state parameter. Different power maintenance control instructions correspond to different target discharge currents or target discharge powers, so that the portable energy storage device is controlled to ultimately output the target discharge current or target discharge power, and the electronic device is charged, and ultimately the first state parameter of the electronic device is adjusted to achieve the purpose of maintaining the battery of the electronic device and extending the service life of the electronic device.

[0044] 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.

[0045] 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 by wire, the portable energy storage device and the electronic device can be connected by 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 through the charging cable. It can be understood that a special 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 through wired communication.

[0046] 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 equipment is required; or the energy storage device and the electronic device can 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.

[0047] 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.

[0048] 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.

[0049] In one embodiment, a corresponding application may also be installed in the electronic device, and the relevant first status parameter may be obtained through the user's authorization of the application.

[0050] In other embodiments, obtaining the first state parameter of the electronic device connected to the portable energy storage device includes: determining the first state parameter of the electronic device according to the 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 when the portable energy storage device cannot establish communication with the electronic device, the portable energy storage device can still implement the charge and discharge control method.

[0051] 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.

[0052] In one embodiment, the portable energy storage device is a device with a magnetic attraction function, such as Figure 4As shown. The portable energy storage device and the electronic device can be in point or surface contact by means of 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, the sampled second temperature can also be calibrated with a preset calibration coefficient 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.

[0053] 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, the preset time interval can also be set to the millisecond level, which is 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, which will not be repeated here.

[0054] After obtaining the second state parameter of the portable energy storage device, step S12, that is, generating a corresponding power-maintaining control instruction according to the first state parameter, specifically 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 the 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 improving the service life of the electronic device and the portable energy storage device.

[0055] 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 through 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 best use 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.

[0056] It can be understood that when generating a power maintenance control instruction, it can also be based on the state parameters of the party that currently needs to be maintained. For example, when the first state parameter of the electronic device exceeds the expected operating state, the corresponding power maintenance control instruction is generated according to the first state parameter to control the discharge of the portable energy storage device, and then adjust the first state parameter of the electronic device to the expected operating state. Usually the expected operating state refers to the operating state set by the user or preset by the device, and the performance of the device is minimally damaged in this operating state. For another example, when the second state parameter of the portable energy storage device exceeds the expected operating state, the corresponding power maintenance control instruction can be generated according to the second state parameter, so as to control the charging and discharging of the portable energy storage device, and then adjust the second operating state of the portable energy storage device to the expected operating state. The expected operating state of the electronic device and the expected operating state of the portable energy storage device can be specifically set according to the requirements of their respective product performance, and can be the same or different. Through the above-mentioned charging and discharging control method, the battery maintenance of the electronic device and the portable energy storage device can be achieved simultaneously.

[0057] In some embodiments, when the first state parameter includes at least one of the first temperature and the first remaining power, a corresponding power-maintaining control instruction is generated according to the first state parameter, including at least one of the following: first, when the first temperature is not within the preset operating temperature range of the electronic device, a first power-maintaining control instruction is output; the first power-maintaining 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; second, when the first remaining power is greater than the first power threshold, a second power-maintaining control instruction is output, and the second power-maintaining control instruction is 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; third, when the first remaining power is less than the second power threshold, a third power-maintaining control instruction is output, and the third power-maintaining control instruction is 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; 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. The above four situations are introduced and explained below.

[0058] In some embodiments, in the above-mentioned charge and discharge control method, a corresponding power-maintaining control instruction is generated according to the first state parameter, including: when the first temperature is not within the preset operating temperature range of the electronic device, a first power-maintaining control instruction is output; the first power-maintaining 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 the temperature range corresponding to the preset electronic device when it is in a better 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. Usually, 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, the discharge control can be achieved by reducing the discharge current, or by reducing the discharge power, and the two 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, thereby avoiding the problem of heat damage to the battery of the electronic device caused by the portable energy storage device using a large current or a 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 is not affected by excessive temperature, and extending the battery life.

[0059] 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 where the first temperature is located. The parameter adjustment process still needs to take into account the requirement of the shortest charging time, so as to achieve fast charging of electronic devices while ensuring that the temperature rise of the battery caused by charging of the electronic device is reduced. For example, the temperature above 35°C can be divided into different intervals, each interval corresponds to a different discharge power, the higher the temperature, the smaller the corresponding discharge power, and the discharge power decreases step by step with the increase of temperature.

[0060] In some embodiments, in the above-mentioned charge and discharge control method, a corresponding power maintenance control instruction is generated according to the first state parameter, including: when the first remaining power is greater than the first power threshold, a second power maintenance control instruction is output, and the second power maintenance control instruction is 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. The first power threshold can be used to characterize that the current electronic device is close to a fully charged state. 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 being fully charged. At this time, the discharge speed of the portable energy storage device is reduced, such as reducing the discharge current, so that when it is close to being fully charged, the electronic device is charged with a small current or a small 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.

[0061] In some embodiments, in the above-mentioned charge and discharge control method, the corresponding power maintenance control instruction is generated according to the first state parameter, including: when the first remaining power is less than the second power threshold, a third power maintenance control instruction is output, and the third power maintenance control instruction is 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. The second power threshold refers to the preset minimum remaining power of the electronic device when it is in a better charging state. If it is lower than the second power threshold, it can be considered that the current electronic device is in a low power state. For example, the second power threshold can 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 speed, such as 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 small, the portable energy storage device charges the electronic device by reducing the discharge speed, such as reducing the discharge current, and slowly charges the electronic device to the second power threshold at a low charging speed, so as to avoid damage to the battery by fast charging when the battery is in a low power state, and extend the battery life.

[0062] In one embodiment, in the above-mentioned charge and discharge control method, a corresponding power control instruction is generated according to the first state parameter, including: 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. 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 kept below 80%, which can avoid the damage to the battery caused by the electronic device being in a full or overcharged state for a long time, and can extend the service life of the battery of the electronic device. In one embodiment, the portable energy storage device can be provided with a corresponding adjustment button or 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.

[0063] In some embodiments, the portable energy storage device is provided with 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.

[0064] At this time, the above-mentioned charge and discharge control method further includes at least one of the following:

[0065] First, when the portable energy storage device is in the power conservation mode, a step of generating a corresponding power conservation control instruction according to the first state parameter is executed;

[0066] Second, when the portable energy storage device is in a custom mode, a corresponding discharge control signal is generated according to the discharge preference configuration information customized by the user to control the portable energy storage device to discharge so as to charge the electronic device;

[0067] 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.

[0068] 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 the electronic device.

[0069] Specifically, the power conservation mode may refer to a mode in which battery maintenance is achieved by limiting the charging state of the electronic device, thereby extending the battery life. That is, when the portable energy storage device is in the power conservation mode, S12 is executed, that is, the step of generating a 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 in which battery maintenance is achieved 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, when the portable energy storage device is in the power conservation mode, the step of generating a corresponding power conservation control instruction according to the first state parameter and the second state parameter is 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, so as to ensure that the state of the electronic device and / or the portable energy storage device is always in a better operating state, thereby achieving battery maintenance of the electronic device and / or the portable energy storage device and realizing the power conservation function.

[0070] 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 (i.e., 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 charged, 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.

[0071] 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 requirements of different electronic devices.

[0072] In one embodiment, various modes of the portable energy storage device can trigger the entry into 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 of 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 custom configuration is received, the custom mode is entered by default; when the user controls the power conservation mode switch button, the power conservation mode is entered, otherwise the normal mode is entered.

[0073] In some embodiments, the following steps may be used to enter or exit the power conservation mode: when the first state parameter meets the preset power conservation condition, control the portable energy storage device to enter the power conservation mode; or receive a mode switching instruction input by the user, and control 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 the 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 power conservation mode is entered, 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 the physical button on the portable energy storage device, thereby restoring to the normal mode, so as to charge the mobile phone to 100% as soon as possible.

[0074] When the first state parameter meets the preset power conservation condition, the above method controls the portable energy storage device to enter the power conservation mode, realizes the automatic start of the power conservation mode, and can timely adjust the charging state of the electronic device or the discharging state of the portable energy storage device to improve the battery life; the above method controls the portable energy storage device to enter the power conservation mode after receiving the mode switching instruction input by the user, which can meet the user's power conservation needs for the electronic device and / or the portable energy storage device.

[0075] In some embodiments, the preset power conservation conditions can be set according to 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 the first power threshold, the first remaining power is less than the second power threshold, and the first remaining power is greater than or equal to the target power.

[0076] In some embodiments, the electronic device and / or the portable energy storage device can perform human-computer interaction, and the interaction methods include but are not limited to keyboard, mouse, remote control, touch pad or voice control device, etc. Through the above interaction methods, the user enables the electronic device to send a mode switching instruction to the portable energy storage device through the server, or directly send a 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.

[0077] In some embodiments, the above-mentioned charge and discharge control method also 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 according to the displayed mode identifier. Specifically, a display screen may be provided in the portable energy storage device, and the display screen 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 through 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.

[0078] In one embodiment, the above-mentioned charge and discharge control method also 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 it can be output through voice, etc., to prompt the user.

[0079] In some embodiments, when the first state parameter includes a first temperature and a charging speed, the above-mentioned charge and discharge control method also includes: when the first temperature is in a preset low temperature range, generating a heating instruction; the heating instruction is used to control the processor of the electronic device to enter a high-frequency operation state, or control a preset heating device to heat so that the first temperature of the electronic device is higher than the preset low temperature range.

[0080] Among them, the preset low temperature range refers to the temperature range in which the charging speed of the electronic device will be affected and slowed down, that is, the temperature at which the battery activity is low. For example, the preset low temperature range can be (-10℃~5℃), and in other embodiments, the preset low temperature range can also be set to be lower than 0℃. When the first temperature of the electronic device is in the preset low temperature range, it can be determined that the current electronic device is currently in a state where heating is required. In another embodiment, in addition to considering the preset low temperature range, the charging speed of the current electronic device also needs to be considered at the same time. Only when the first temperature is in the preset low temperature range and the charging speed is less than the preset speed threshold, it will be confirmed that it is in a state where heating is required and a heating instruction will be generated. Usually, when the 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 charging speed of the current 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 can be achieved, and the heating of the battery cell can be achieved by its own charging heat release to maintain the activity of the battery, and there is no need to control the electronic device to perform a heating operation. In one embodiment, the preset speed threshold can be a preset charging power threshold, which can be 5W.

[0081] 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 an extreme cold mode. When it is detected that the first state parameter exits the above trigger condition, the extreme cold mode is exited.

[0082] The above-mentioned charge and discharge control method can activate the battery of the electronic device in a low temperature environment, improve the battery activity of the electronic device, and thus improve the charging rate of the electronic device by heating the electronic device whose first temperature is in a preset low temperature range and whose charging speed is less than a preset speed threshold, so that the temperature of the electronic device is always maintained between 0 and 35°C during the charging process, thereby achieving the purpose of maintaining the battery life. The specific temperature range can be set according to the environment and the performance of the device, and is not limited to the above-mentioned embodiments.

[0083] 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.

[0084] In some embodiments, the heating instruction is used to control the processor of the electronic device, such as the CPU (Central Processing Unit) or GPU (Graphics Processing Unit, graphics and video processor), to enter a high-frequency operation state, so that the processor executes related instructions at a higher frequency, increasing the power consumption and heat of the electronic device, so that the heat generated maintains or improves the battery activity. If the electronic device does not receive the heating instruction or receives a stop heating instruction, it will exit the high-frequency operation state and perform processor frequency operation control according to a preset operation strategy.

[0085] In other embodiments, the heating instruction is used to control a preset heating device to heat so that the first temperature of the electronic device is higher than a preset low temperature range. Exemplarily, 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. Exemplarily again, 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.

[0086] In some embodiments, the above-mentioned charging and discharging control method further includes: the step of obtaining the schedule information of the electronic device, the current running program information, and the user's charging habit information. At this time, generating the corresponding power maintenance control instruction according to the first state parameter includes: generating the power maintenance control instruction according to at least one of the first state parameter, schedule information, current running program information, and user charging habit information. The above-mentioned method can generate the power maintenance control instruction according to the first state parameter of the electronic device, schedule information, current running program information, and user charging habit information, so that the charging of the electronic device can be controlled based on more comprehensive state parameters, thereby achieving the purpose of battery maintenance of the electronic device and meeting the user's power usage needs.

[0087] Schedule information, current running program information, and user charging habit information can all be obtained under the premise of user authorization. Among them, schedule information includes information such as outing time and meeting arrangements. For example, when the user sets the schedule information as: morning meeting from 9:00 to 10:00 on Monday morning, the corresponding power maintenance control instruction is used to control the portable energy storage device to charge the electronic device to full power before 9:00 in the morning, that is, 100%, so as to facilitate user use. For another example, when the user sets the schedule to go out at 3 pm, the portable energy storage device can be controlled to charge the electronic device to full power before 3 pm, and the limitation of the first upper limit of the remaining power is no longer considered to meet the user's use needs. In addition, by obtaining the schedule information, the charging and discharging speed can also be adjusted according to the current actual remaining charging time and the actual charging time required by the electronic device, such as charging at a lower charging speed in the early stage, and charging the electronic device to full power in the later stage, so as to avoid the electronic device being fully charged or overcharged for a long time due to long-term charging, and the battery maintenance of the electronic device can be realized, and the service life of the electronic device can be extended.

[0088] In some embodiments, the current running program information of the electronic device can also be obtained. The type and number of applications running in the electronic device will cause the electronic device to generate other running heat in addition to the heating during charging. Therefore, when charging the electronic device with a portable energy storage device, the current running application of the electronic device can be fully considered. For example, when the electronic device is currently running a heavy-loaded application such as navigation, camera, video chat, etc., a higher heat will be generated. At this time, the corresponding power control instruction can be generated according to the first state parameter and the current running 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 the third power threshold, the portable energy storage device is controlled to output the minimum output power to charge the electronic device. The minimum output power is greater than the current power consumption of the electronic device, thereby ensuring that the electronic device is charged with the minimum power under the premise of ensuring that the power of the electronic device is not reduced, thereby avoiding the temperature rise of the electronic device from being too high and affecting the use. Among them, 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 failure 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 the minimum power.

[0089] 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 according to the first remaining power of the electronic device, and the appropriate discharge power is determined according to the predicted rechargeable time and the temperature rise rate corresponding to different charging powers to charge the electronic device, so as to meet the charging needs of the electronic device and not cause 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 failure and heating conditions in the past period of time, and the heating conditions. For example, if you charge directly with 20W, the heat will be greater, and it may drop to 5W or even lower after 5 minutes of charging, while the heat generated by charging with 15W can support 10 minutes or even longer, thereby shortening the charging time of the mobile phone.

[0090] The user's 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 habitual power consumption time and the charging speed, etc. Therefore, the power maintenance control instruction can be comprehensively generated according to the user's power consumption habits and other relevant factors. For example, when the first remaining power of the electronic device is greater than the 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 the scenario where other energy storage devices are used to charge the portable energy storage device and the portable energy storage device is used to charge the electronic device, that is, when the portable energy storage device is in a scenario of 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%).

[0091] In one embodiment, the above-mentioned charging and discharging control method also 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 conservation control instruction based on the operating power; the power conservation 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.

[0092] 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, so as to achieve battery maintenance of the electronic device and extend the battery life. Specifically, the operating power required for the operation of the electronic device is first determined according to 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.

[0093] In one embodiment, the charging state of the portable energy storage device can also be controlled according to the charging state parameters of the portable energy storage device. Therefore, the above-mentioned charging and discharging control method also includes: when the portable energy storage device is connected to the charger, obtaining the charging state parameters of the portable energy storage device; generating a charging request instruction according to 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, so as to adjust the charging state parameters of the portable energy storage device.

[0094] When it is detected that the portable energy storage device is connected to the charger, it can be confirmed that the current portable energy storage device is 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., will be obtained, so that a corresponding charging request instruction is generated according to 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 extend the battery life of the portable energy storage device.

[0095] In one embodiment, the charging state 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 state 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 state parameter of the portable energy storage device, so as to realize the charging control of the portable energy storage device, and then adjust the charging state parameter of the portable energy storage device so that it is in a better operating state, thereby extending the life of the battery.

[0096] See also Figure 6 , Figure 6 is a schematic diagram of the structure of the charge and discharge control device provided in the embodiment of the present application. In some embodiments, the charge and discharge control device 20 may include a plurality of functional modules composed of computer program segments. The computer program of each program segment in the charge and discharge control device 20 may be stored in the memory of the electronic device and executed by at least one processor to execute (see Figure 5 Description) Function of charge and discharge control.

[0097] In this embodiment, the charge and discharge control device 20 can be divided into multiple functional modules according to the functions it performs. The functional modules may include: a state parameter acquisition module 201 and a control instruction generation module 202.

[0098] The state parameter acquisition module 201 may be used to acquire a first state parameter of an electronic device connected to the portable energy storage device.

[0099] The control instruction generation module 202 can be used to generate a corresponding power conservation control instruction according to the first state parameter; the power conservation 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.
