Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.

In the related art, the battery structure of the terminal device generally includes the following two schemes:

Firstly, the battery cell structure with large capacity is adopted, so that the cruising ability of the terminal equipment is ensured, and the cost can be conveniently controlled.

Second, adopt the double cell structure of the same capacity, the endurance is good but the cost is high.

In the above two battery structures, the charging mode is generally fixed, and the battery is charged according to a set or linear power. In some scenarios, there may be a problem of poor user experience. For example, in a scenario of charging while using (e.g., a game while charging), there may be two power consumption of the charging process and the load, and the heat generated by the two power consumption may cause a more serious problem of heat generation of the terminal device.

In the related art, when solving the problem of heat generation existing in the usage scenario while charging, the following method is generally adopted:

The charging mode of the related art is maintained, and the amount of heat generation is reduced by reducing the Central Processing Unit (CPU) frequency during the charging. However, in this way, the CPU frequency is reduced, and the performance of the program being used by the user, such as the game performance, is reduced. This approach can severely impact the user's experience.

To solve the problems in the related art, the present disclosure proposes a charge and discharge system including: a control chip; the first battery and the second battery, the capacity of the second battery is greater than the capacity of the first battery, the capacity of the first battery is not greater than the set threshold; the charging management chip is connected with the control chip, is connected with the first battery through the first branch and is connected with the second battery through the second branch, and is also used for being connected with the charger; wherein, control chip is used for: the first branch or the second branch is communicated according to the current usage field Jing Kongzhi so as to charge the first battery or the second battery through the charging management chip. In the structure of the present disclosure, according to different usage scenarios of charging, different charging modes may be dynamically selected, and the charging modes are more flexible. In this embodiment, under the corresponding use scenario, only the first battery can be controlled to be charged, and the charging current and the charging power can be reduced in combination with the capacity limitation of the first battery, so that the power consumption in the charging process is reduced, and the heating value in the charging process is effectively reduced. And then can reduce complete machine heat, under the prerequisite that does not influence the use experience, more laminating user's user demand and effectively promote and use experience.

In an exemplary embodiment, for example, in a use scenario with larger power consumption, the charging and discharging system of the embodiment may be applied to a terminal device. The terminal equipment can be electronic equipment such as a mobile phone, a tablet personal computer, a notebook computer and the like.

As shown in fig. 1, the charge and discharge system in this embodiment includes: the battery management system comprises a control chip 10, a first battery 20, a second battery 30, a charging management chip 40, a first branch 101 and a second branch 102.

The capacity of the second battery 30 is greater than the capacity of the first battery 20, and the capacity of the first battery 20 is not greater than the set threshold.

The charge management chip 40 is connected to the control chip 10, to the first battery 20 via the first branch 101, to the second battery 30 via the second branch 102, and the charge management chip 40 is also used to connect to the charger 100.

Wherein, control chip 10 is used for: the first leg 101 or the second leg 102 communicates according to the current usage field Jing Kongzhi to charge the first battery 20 or the second battery 30 through the charge management chip 40.

In this embodiment, the control chip 10 may be a System On Chip (SOC), such as a CPU of an integrable terminal device. The second battery 30 still employs a large-capacity battery, for example, the capacity of the second battery 30 is set to 5000mAh. The set threshold value is set to 1000mAh, for example, and the capacity of the first battery 20 is smaller than or equal to the set threshold value and smaller than the capacity of the second battery 30.

The capacity of the second battery 30 and the capacity of the first battery 20 may be a difference value or a ratio that satisfies a set value. For example, the capacity of the second battery 30 is 5 times or 10 times that of the first battery 20, and the capacity of the first battery 20 is set to 1000mAh or 500mAh. In the present embodiment, the capacity of the first battery 20 is set to 500mAh.

In this embodiment, the control chip 10 can learn the system power consumption or load condition according to the charge and discharge conditions of the charge management chip 40. The usage scenario comprises at least: the first scene and the second scene, and the current usage scene may be the first scene or the second scene. The power consumption in the first scene is larger than that in the second scene, and the first scene is as follows: the game scene is charged while the second scene is as follows: only the charging scenario. The control chip 10 is in a first state (representing a heavy load state) in a first scene and in a second state (representing a light load state) in a second scene.

The control chip 10 adjusts the charging mode according to different current usage scenarios.

In one example, when the control chip 10 determines that the system load 50 is in the first scenario, the control chip may control the first branch 101 to be connected and the second branch 102 to be disconnected, and the charging management chip (CHARGER IC) 40 may charge the system load 50 and the first battery 20 simultaneously based on the connection to the charger (adapter) 100. The system load 50 includes, for example, a game load. The first scenario is, for example, a scenario of a game while charging, where the control chip 10 is generally in a first state, i.e., a reloading state, and the system power consumption includes the system load 50 power consumption and the charging power consumption.

In this example, the capacity of the first battery 20 is small, so that the charging current and the charging power can be effectively reduced, the power consumption occupation in the charging process is small, the charging time is short, the heating degree in the charging process is reduced, the power consumption at the system load 50 can be kept, and the experience of the user in performing operations such as games in the charging process is effectively improved.

In another example, when the control chip 10 determines that the system load 50 is in the second scenario, the system load 50 consumes less power, and can control the second branch 102 to be connected and the first branch 101 to be disconnected, and the charge management chip 40 charges the second battery 30 based on the connection with the charger 100. In this example, the capacity of the second battery 30 is large, and the charging current and the charging power are large. The second scenario is, for example, a charging-only scenario, in which the control chip 10 is generally in the second state, i.e., the light load state.

In the embodiment of the disclosure, the user experience can be improved at least from the following two aspects: in the first scene, the power consumption and heat in the charging process can be reduced, the use experience of a user such as game experience is maintained, and the charging time can be shortened. In the second scenario, a better charging experience and charging speed can be maintained.

Therefore, corresponding charging modes are selected in a plurality of scenes, and different requirements of users can be effectively attached to the different scenes.

In an exemplary embodiment, as shown in fig. 1, the charging and discharging system in this embodiment further includes: a charging path management unit (power path IC) 60.

The charge path management unit 60 is connected to the control chip 10 through the charge management chip 40. The charge management chip 40 or the second battery 30 supplies power to the system load 50 through the charge path management unit 60.

The control chip 10 obtains the charge and discharge conditions through the charge management chip 40, for example, the power consumption condition of the system load 50 at the charge path management unit 60 can be obtained, and the power consumption of the current system load 50 can be obtained according to the power consumption condition, thereby obtaining the state of the control chip 10, such as a heavy load state or a light load state.

In this embodiment, the control signal of the control chip 10 can inform the charging path management unit 60 through the charging management chip 40. The charging path management unit 60 controls the communication with the power supply branch between the charging management chips 40 according to the control signal; or to control the communication with the power supply branch between the second batteries 30.

In one example, when the charger 100 is connected, the control chip 10 may control: the charge management chip 40 supplies power to the system load 50 through the charge path management unit 60. In another example, when the charger 100 is not connected, the control chip 10 may control: the second battery 30 supplies power to the system load 50 through the charging path management unit 60.

When the system load 50 is present and the charger 100 is connected, the power supply of the charge management chip 40 may include two parts. Some of which power the system load 50 through the charging path management unit 60, some of which charge the first battery 20 through the first branch 101, or charge the second battery 30 through the second branch 102.

In an exemplary embodiment, as shown in fig. 1, the charge and discharge system of the present embodiment further includes: and a switching unit 70.

The switching unit 70 may be a switching chip (switch IC) or be provided as a single pole double throw switch. The charging management chip 40 is controlled to be communicated with the first branch circuit 101 by controlling different communication states of the switch unit 70 so as to charge the first battery 20; or the charge management chip 40 is controlled to communicate with the second branch 102 to charge the second battery 30.

In the present embodiment, whether or not the branch connected to the charge management chip 40 is connected is controlled by the switching unit 70 connected to the first branch 101 and the second branch 102.

In other examples of the present disclosure, a switch may be further disposed on each of the first branch 101 and the second branch 102, and by controlling the on or off of the switches on the two branches, whether the branch where the switch is located is connected is controlled.

In an exemplary embodiment, as shown in fig. 1, the charge and discharge system of the present embodiment further includes: the comparing unit 80 is connected to the control chip 10.

The first battery 20 is connected to the second battery 30 through the comparing unit 80; the control chip 10 is for: the voltage relationship of the first battery 20 and the second battery 30 is acquired by the comparison unit 80.

In this embodiment, the comparing unit (comparator IC) 80 is used for detecting the voltage levels of the first battery 20 and the second battery 30, and reporting the voltage relationship between the first battery 20 and the second battery 30 to the control chip 10.

In an exemplary embodiment, as shown in fig. 1, the charge and discharge system of the present embodiment further includes: the load switching chip 90 is connected to the control chip 10.

The first battery 20 is connected to the second battery 30 through the load switching chip 90. The control chip 10 is for: by controlling the load switching chip 90 to communicate, the first battery 20 is controlled to communicate with the second battery 30 so that the first battery 20 supplies power to the second battery 30.

The usage scenario further includes a third scenario, and the embodiment may be applied to the third scenario. The third scenario satisfies the following three constraints: the charger is not connected, the control chip 10 is in the second state (i.e., light-load state) and is not in the first state (heavy-load state), and the control chip 10 knows that the voltage of the first battery 20 is greater than the voltage of the second battery 30 according to the comparison unit 80.

In the third scenario, the control chip 10 controls the load switching chip 90 to communicate so as to control the first battery 20 to communicate with the second battery 30, so that the first battery 20 can supply power to the second battery 30. In the embodiment of the present disclosure, the first battery 20 may also charge the second battery 30 under a suitable scenario, so as to effectively expand the use scenario of the present embodiment.

It can be appreciated that, in the embodiment of the present disclosure, the second battery 30 is a main power supply battery of the terminal device, and only the second battery 30 may be counted when performing operations such as electric quantity counting in the terminal device.

In an exemplary embodiment, the embodiment of the disclosure further provides a terminal device, including a charging and discharging system as shown in fig. 1. In fig. 1, the dashed connection represents control signal (control) transmission, and the solid connection represents power supply (power) transmission.

In an exemplary embodiment, the embodiment of the present disclosure further provides a charging and discharging method, which is applied to a terminal device, where the terminal device includes the charging and discharging system shown in fig. 1.

As shown in fig. 2, the method of the present embodiment may include the steps of:

s210, determining a charging mode according to the current use scene.

And S220, controlling the first branch or the second branch to be communicated under a preset charging mode so as to charge the first battery or the second battery through the charging management chip.

In step S210, in conjunction with the embodiment corresponding to fig. 1, the control chip 10 of the terminal device may determine the current usage scenario according to the charge and discharge conditions of the charge management chip 40. The charge and discharge conditions can reflect the system power consumption or load conditions, and in combination with different use scenarios, in this step, the control chip 10 can adopt different charging modes.

In step S220, in conjunction with the embodiment corresponding to fig. 1, the capacity of the second battery 30 is greater than the capacity of the first battery 20, and the capacity of the first battery 20 is not greater than the set threshold. For example, the capacity of the first battery 20 is 500mAh, and the capacity of the second battery 30 is 5000mAh. The charge management chip 40 is connected to the first battery 20 through the first branch 101 and to the second battery 30 through the second branch 102.

In this step, under the control of the control chip 10, the charge management chip 40 can control the first branch 101 to be connected and the second branch 102 to be disconnected, so as to charge the first battery 20. Or the first branch 101 is controlled to be disconnected and the second branch 102 is controlled to be connected to charge the second battery 30.

In an exemplary embodiment, the method of the present embodiment includes steps S210 to S220 in fig. 2, and the method of the present embodiment may further include: s200, determining the current use scene.

The embodiment of step S200 may include one of the following:

S201, determining that the usage scene is a first scene in response to the connection of the charger and the control chip being in the first state.

S202, determining that the usage scene is a second scene in response to the connection of the charger and the control chip being in the second state.

And S203, determining the use scene as a third scene in response to the fact that the charger is not connected and the control chip is in the second state, and when the voltage of the first battery is larger than that of the second battery.

The power consumption of the control chip in the first state is larger than that in the second state. In connection with the corresponding embodiment of fig. 1, the first state is used to characterize that the control chip 10 is in a heavy load state, for example, the power consumption occupied by the system load 50 is greater than or equal to the power consumption threshold; the second state is used to characterize the control chip 10 in a light load state, e.g., the system load 50 occupies less than a power consumption threshold.

The control chip 10 obtains the charge and discharge conditions through the charge management chip 40, for example, the power consumption condition of the system load 50 at the charge path management unit 60 can be obtained, and the current power consumption of the system load 50 can be obtained according to the power consumption condition, so that the state of the control chip 10, such as a heavy load state or a light load state, is obtained.

In step S201 and step S202, when the terminal device is connected to the charger 100, the corresponding usage scenario is the first scenario or the second scenario according to the different states of the control chip 10.

In step S203, when the terminal device is not connected to the charger 100 and the control chip is in a light-load state, the control chip 10 may obtain the voltage relationship between the first battery 20 and the second battery 30 according to the comparing unit 80. When the voltage of the first battery 20 is greater than the voltage of the second battery 30 at this time, the corresponding usage scenario is a third scenario. In a third scenario, the first battery 20 may be utilized to power the second battery 30.

In an exemplary embodiment, the preset charging mode is a first mode. As shown in fig. 3, the method of the present embodiment includes the steps of:

And S300, connecting a charger, determining whether the control chip is in a first state, and if so, executing step S301. If not, step S401 is performed.

S302, determining that the charging mode is a first mode in response to the usage scene being the first scene.

S303, under the first mode, the first branch is controlled to be communicated through the control switch unit, the second branch is controlled to be closed, and the first battery is charged by the first charging current through the charging management chip.

In step S300, in conjunction with fig. 1 and the foregoing embodiments, after the charger 100 is connected, the control chip 10 may obtain the charge and discharge conditions through the charge management chip 40, for example, may know the power consumption condition of the system load 50 at the charge path management unit 60, and determine whether the system load is in the first state, i.e. the heavy load state. If not, the control chip 10 is considered to be in the second state, i.e., the light load state.

The embodiment of step S301 can refer to step S201, and will not be described herein.

In step S302, according to the first scenario, the corresponding charging mode is determined to be the first mode.

In step S303, the control chip 10 controls the communication mode of the switching unit 70, so that the switching unit 70 is connected to the first branch circuit 101 and disconnected from the second branch circuit 102. Thus, the charge management chip 40 charges the first battery 20 with the first charge current through the first branch 101. Wherein, in combination with the capacity of the first battery 20, the first charging current is a small current parameter and is not greater than (less than or equal to) a preset current threshold.

In this step, as shown in fig. 4, when the charger 100 is connected, the charging management chip 40 may also supply power to the system load 50 through the charging path management unit 60.

In an exemplary embodiment, the preset charging mode is the second mode. Still referring to fig. 3, the method of this embodiment includes the steps of:

s401, determining that the usage scene is a second scene in response to the connection of the charger and the control chip being in the second state.

And S402, responding to the use scene as a second scene, and determining that the charging mode is a second mode.

S403, under a second mode, controlling the charging management chip to supply power for a system load; and controlling the first branch to be communicated, and closing the second branch to charge the first battery through the charging management chip.

The embodiment of step S401 may refer to step S202, which is not described herein.

In step S402, according to the second scenario, the corresponding charging mode is determined to be the second mode.

In step S403, in the second mode, the control chip 10 controls the communication mode of the switching unit 70 so that the switching unit 70 communicates with the second branch 102 and is disconnected from the first branch 101. Thus, the charge management chip 40 charges the second battery 30 with the second charge current through the second branch 102. The second charging current is greater than the current threshold and greater than the first charging current.

As shown in connection with fig. 4, the second battery 30 may supply power to the system load 50 after being disconnected from the charger 100, or after the second battery 30 is fully charged in the present embodiment, disconnected from the charger 100.

In an exemplary embodiment, as shown in fig. 5, the method of the present embodiment includes the steps of:

S500-1, determining whether a charger is connected. If yes, executing the step S500-2; if not, go to step S504.

And S501, determining the use scene as a third scene in response to that the charger is not connected and the control chip is in the second state, and when the voltage of the first battery is greater than that of the second battery.

And S503, under the third mode, controlling the load switching chip to be communicated so as to control the first battery to be communicated with the second battery, wherein the first battery supplies power for the second battery.

S504, controlling the disconnection of the load switching chip so as to control the disconnection of the first battery and the second battery.

In this embodiment, the decision sequence from step S500-1 to step S500-3 is only shown schematically, and the decision sequence of the three conditions can be adjusted as required.

The embodiment of step S501 may refer to step S203, and will not be described herein.

In step S502, according to the third scenario, it is determined that the corresponding charging mode is the third mode.
