The present disclosure relates to the communication field, for example, to a terminal and a control method of multi-path power supplying.
The battery generally used in the terminal is a liquid electrolyte battery, and the electrodes adopt a single positive electrode and a single negative electrode. A corresponding power-supplying management circuit is encapsulated with the battery for providing over-discharge protection, over-current protection, over-voltage protection, voltage stabilization output for the battery, and providing a corresponding battery power supply scheme to ensure that the battery can provide controllable voltage and current to each application module of the terminal and supply power to the terminal. A problem in such battery power supply scheme is that the terminal supplies power from a same place of the battery, which limits the flexibility of the power path selection. Once multiple application modules of the terminal interfere with each other through the power-supplying paths, the interference cannot be solved or optimized. The reason is that there is no room for adjustment when only one power-supplying path is provided. Meanwhile, since only one power-supplying path is provided, the length and width of the battery internal wiring and the terminal internal wiring will be limited, impedance of the wirings is increased, and utilization efficiency of the battery energy is reduced.
With the gradually maturing of the all-solid-state battery technology and its various performances are gradually improved, all-solid-state batteries are able to achieve multi-path charging and discharging. Using such type of battery can solve the problems existing in the battery scheme of the single power-supplying path to some extent. However, when the battery adopted by the terminal supports the multi-path charging and discharging, the battery is not effectively managed in the existing art and the power supply efficiency is not high.
The embodiment of the present disclosure provides a terminal. The terminal includes a battery module having multiple power-supplying paths, multiple power-supplying management modules that are in one-to-one correspondence with each of the multiple power-supplying paths and a power supply control module; where each of the multiple power-supplying paths of the battery module is connected to a power-supplying management module, a first end of each power-supplying management module is connected to a power-supplying path, a second end is connected to the power supply control module, and a third end is connected to at least one function module in the terminal.
The battery module is configured to supply power to the at least one function module in the terminal through multiple independent power-supplying paths.
The power supply control module is configured to send a power-supplying control instruction to each power-supplying management module based on a power-supplying demand of each of the at least one function module in the terminal.

Exemplary embodiments of the present disclosure will be described in detail with reference to the drawings.
The embodiment of the present disclosure provides a terminal. The terminal may control and manage the multi-path power control. As shown in
The battery module 110 is configured to supply power to the at least one function module in the terminal through multiple independent power-supplying paths.
The power supply control module 120 is configured to send a power-supplying control instruction to each power-supplying management module 130 on a power-supplying demand of each of at least one function module in the terminal.
Each of power-supplying management module 130 is configured to control power supplying of a power-supplying path managed by the each power-supplying management module 130 according to the power-supplying control instruction sent by the each power supply control module 120.
In the embodiment of the present disclosure, the battery module 110 may include: a chemical reaction module for power supplying, a battery power-supplying management module for implementing functions such as protection and control and at least one of a connector and a resilient piece which are connected to a relevant circuit of a mainboard of the terminal. The battery module 110 of the embodiment is a battery module capable of implementing the multi-path power supply, and the type of the battery module may be, but is not limited to, an all-solid-state battery.
In the embodiment of the present disclosure, positive and/or negative electrodes and other related signals (such as a battery ID and battery temperature information detected by a thermistor) are led out from the battery module 110, and supply power to different function modules in the terminal separately. Since different power-supplying paths for different function modules are separated, thus different function modules do not interfere with each other through the power-supplying paths. In one embodiment, the power-supplying paths may also be partially separated (such as a case of only sharing a power backflow plane (sharing a negative electrode)), so that different function modules do not interfere with each other through the power-supplying paths. Such multi-path power supply scheme is capable of solving problems, such as an interference problem of sharing the power supply between a radio frequency module and a baseband module of the terminal, and an audio noise problem caused by mutual influence of backflows of the radio frequency module and an audio module. In addition, through a reasonable design, a length of the power-supplying path for each function module may be shortened as much as possible, which can fundamentally reduce the external radiation interference and improve power utilization efficiency.
In the embodiment of the present disclosure, each function module in the terminal is used for implementing each function of the terminal, for example, the function module of the terminal may include a memory, a central processing unit, and an input/output device, etc.
In the embodiment of the present disclosure, the power-supplying management module 130 connected to each power-supplying path is configured to perform the power supply control on the corresponding power-supplying path, including control of a current magnitude, control of turning on or off of the power-supplying path. The power-supplying management module 130 connected to each power-supplying path is not independent, but is connected to the power supply control module 120 through a bus (such as an I2C bus, etc.), thereby implementing a system-level control for supplying power to the terminal. In this embodiment, the power-supplying management module 130 may be an independent management module, or may be integrated inside other modules of the terminal, such as integrated inside the power-supplying management module.
The system-level control for supplying power to the terminal implemented by each power-supplying management module 130 under the control of the power supply control module 120 in this embodiment is described below.
In the embodiment of the present disclosure, the power-supplying management module 130 is configured to control at least one of power-supplying current and voltage of the power-supplying path managed by the power-supplying management module 130 based on the power-supplying control instruction when receiving the power-supplying control instruction sent by the power supply control module 120 according to the power-supplying demand of the corresponding function module.
In the embodiment of the present disclosure, the power supply control module 120 is further configured to when the function module (which may be one or more of the multiple function modules) malfunctions, send a control instruction for disconnecting the power-supplying path to the power-supplying management module 130 connected to the malfunctioned function module. When the power-supplying management module 130 receives the control instruction for disconnecting the power-supplying path, the power-supplying path between the battery module 110 and the corresponding malfunctioned function module is disconnected.
In one embodiment, the power supply control module 120 may further send a message to the user to prompt that the function module is malfunctioned after sending the control instruction for disconnecting the power-supplying path to the power-supplying management module connected to the malfunctioned function module.
The malfunction of the function module includes, but is not limited to, short circuit or damage. When function module is short-circuited or damaged, the power-supplying current on the power-supplying path inevitably changes, in this embodiment, the power-supplying management module 130 may periodically collect power supply information on the power-supplying path and feed the power supply information back to the power supply control module 120, and the power supply control module 120 sends the control instruction for disconnecting the power-supplying path at the time of determining that the function module malfunctions according to the power supply information on the power-supplying path. Of course, in this embodiment, the power supply control module 120 may also determine whether the function module malfunctions through other channels, which is not listed herein.
In one exemplary embodiment of the present disclosure, the power supply control module 120 is further configured to acquire working state parameters of at least one module of a group consisting of: each function module in the terminal and the battery module; provide a power supply strategy matched with the working state parameters, and based on the matched power supply strategy, send the power-supplying control instruction to a corresponding power-supplying management module.
In this embodiment, the power supply control module 120 may determine states of each function module and the battery module 110, such as a heating condition and battery energy according to the acquired working state parameters, so that the power-supplying current on some power-supplying paths may be reasonably controlled according to the states of the modules. In this embodiment, the power supply strategy of the modules in different states may be pre-set, so that a strategy matching may be performed directly according to the parameters during the operation, thereby performing the power supply control. The power supply strategy may be flexibly set by those skilled in the art as needed, which is not specifically limited in this embodiment.
Adopting the embodiment is able to effectively improve the power supply efficiency and effectively optimize the power-supplying current distribution, reduce the overall heat generation, and since the multi-path management is adopted for the battery, the power-supplying current of each path may be controlled according to battery parameters, thereby achieving better protection for the battery and prolonging the battery life.
In the above embodiment, the terminal, through independently controlling each power path, can better manage and control each function module of the terminal, and provide safer and smarter user experience while improving power efficiency.
The embodiments of the present disclosure will be described below in detail through the following two application examples.
This application example provides a terminal, as shown in
Control of a current of each power-supplying path may be based on an electrical parameter of each function module of the terminal, and may also be based on safety and reliability requirements for heat generation, short-circuited or damaged module and the like. After obtaining feedback data of the function module of the terminal, the power supply control module 1 may process the feedback data by itself, or prompt the user or propose a request to the user through an output device of the terminal. For example: after an audio amplifier module is damaged due to short circuit, in order to prevent fire by short circuit heating, a power-supplying path for the audio amplifier module is automatically disconnected, and the user is fed back and prompted that “the audio amplifier module is damaged, a horn function cannot be used, and a professional is asked for maintaining or replacing the audio power amplifier module”.
The power supply control module 1 may be integrated into other function modules or may be a separate control module. For example, the power supply control module 1 may belong to a terminal module, or be placed in a module inside the battery.
Communications between the power supply control module 1 and the power management modules 11 as well as may be unidirectional or bidirectional. An interface of the communications or a form of a bus may be various, which may be a communication interface type (an I2C bus, etc.) commonly used in the industry, or a communication interface type of a custom protocol.
An energy storage type of the battery module 2 may be optional, including but is not limited to a commonly used battery or all-solid-state battery.
The path 111 is a circuit connection path of the power supply among the terminal function module 3, the power-supplying management module 11 and the battery module. The battery module 2 supplies power to the function module 3 of the terminal by the power-supplying management module 11.

The path 311 is a circuit connection path of the power supply among the terminal function module 31, the power-supplying management module 310 and the battery module. The battery module 340 performs power supply control on the terminal function module 31 by the power-supplying management module 310. The power-supplying management module 310 communicates with the power supply control module 300 to implement that a power-supplying current is fed back to the power supply control module 300 and the power supply control module 300 controls the power-supplying current through the power-supplying management module 310.
