Description

Technical Field

[0001] The present disclosure relates to the field of terminal battery charging, and in particular to a terminal startup method, a terminal startup device, and a storage medium. Background Art

[0002] When the terminal is turned off for a long time or a special stuck scenario occurs, the terminal battery will be over-discharged, resulting in battery protection. The battery voltage is lower than the initialization voltage (such as 2.7V). The terminal battery in this state can be called a dead battery. For a terminal with a dead battery, it is necessary to connect a charging device to activate the dead battery before it can be recharged and started.

[0003] In the related art, when activating a dead battery in a terminal, the power management IC (Pmic) in the terminal detects that a charging device is connected and sets the current provided by the battery to the default power supply current (such as 500mA), thereby completing the startup of the terminal. However, when the storage specification of the terminal is higher than a certain configuration (such as UFS4.0+256GB and above), the power supply current (such as 700mA) of the terminal startup is higher than the system default power supply current, resulting in the inability to activate the dead battery and the inability to pre-charge and start the terminal.

[0036] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0037] The terminal power-on method provided by the embodiment of the present disclosure is applied to a scenario in which a dead battery in a terminal whose battery voltage is lower than the terminal power-on voltage is activated, and the terminal is powered on during battery pre-charging.

[0038] When the terminal is turned off and not used for a long time, or it gets stuck due to special circumstances, the terminal battery will be over-discharged, causing the terminal battery to perform battery protection. The battery voltage is lower than the voltage required for terminal initialization (such as 2.7V), and the terminal battery cannot support normal startup of the terminal. The battery in this scenario can be called a dead battery. For terminals with dead batteries, you need to connect a charger to activate, charge and start the terminal.

[0039] In the related art, when activating a dead battery in a terminal, the power management chip (powermanagement IC, Pmic) in the terminal detects that a charging device is connected, sets the current provided by the battery to the terminal as the default power supply current (IBUS), and initializes the terminal (UFS initialization). After the initialization is completed, the charging protocol type detection (BC1.2 charging protocol type detection) of the charging device is performed, and the charging protocol type of the charging device [including dedicated charging port (Dedicated Charging Port, DCP), charging downstream port (Charging Downstream Port, CDP), standard downstream port (Standard Downstream Port)] is detected. Port, SDP)】, and based on the charging protocol type of the charging device, different charging currents are set for the terminal battery (such as: DCP: 1.5A, CDP: 1.5A, SDP: 0.5A). It can be understood that the setting of the power supply current of the terminal battery is related to the charging capacity of the charging device. The charging capacity of the charging device with the charging protocol type of DCP and CDP is stronger, so the power supply current is set to a larger value (such as: 1.5A), and the charging capacity of the charging device with the charging protocol type of SDP is weaker, so the power supply current is set to a smaller value (such as: 0.5A). It can be further understood that in the related art, the charging protocol type of the charging device is not detected when setting the default power supply current. In order to ensure the stability of the terminal battery power supply during the terminal initialization process, the default current of the terminal battery is set to a smaller value (such as: 0.5A) when the terminal is initialized.

[0040] However, as terminal storage specifications continue to improve, such as Figure 1 The schematic diagram of the current required for initialization when starting terminals with different storage specifications is shown in the figure. The current required for UFS initialization of terminals with high storage specifications (UFS4.0+256GB and above) (peak value greater than 0.7A) is higher than the current required for UFS initialization of terminals with general storage specifications (peak value close to 0.5A), and is also higher than the default power supply current set when activating the battery (such as: 0.5A). As a result, the battery activation fails and the terminal cannot start in the battery pre-charging stage. Figure 2As shown in the terminal initialization flow chart when activating a dead battery, the related technology activates the dead battery, connects the charging device, and enters the pre-startup process. The power management chip sets the terminal battery's power supply current to the default power supply current (0.5A) and initializes the terminal. Figure 3 A current waveform diagram when activating a dead battery and Figure 4 As shown in the voltage waveform diagram when activating a dead battery, during terminal initialization, since the default current (0.5A) of the terminal battery during initialization is less than the current (0.7A) required for terminal initialization, the power management chip controls the terminal battery to perform system loading, reduce the battery voltage, and increase the battery current. However, the system loading will cause the battery voltage to be lower than the voltage (2.5V) required to maintain normal operation of the power management chip, triggering the terminal to restart due to undervoltage lockout (UVLO), and the dead battery activation fails, and the terminal pre-charge startup fails. In summary, the dead battery activation method in the related art cannot activate a dead battery in a terminal with high storage specifications.

[0041] In view of this, the present disclosure provides a method for starting up a terminal when the battery is low. After the terminal is connected to a charging device, the charging type of the charging device is detected, and according to the charging type, a power supply current is set for the terminal battery, and the terminal is initialized according to the power supply current to control the terminal to start up. Through the present disclosure, after connecting to the charging device, a software strategy is used to solve the problem that a dead battery in a terminal whose startup current is higher than the default power supply current of the battery cannot be activated, and no additional hardware is required, which can save terminal internal space and save costs.

[0042] Figure 5 FIG. 1 is a flow chart of a method for starting a terminal according to an exemplary embodiment. Figure 5 As shown, the method includes step S101 to step S102.

[0043] In step S101 , in response to a target terminal being connected to a charging device, a charging type of the target terminal charged by the charging device is detected.

[0044] Among them, the battery voltage of the target terminal before connecting to the charging device is lower than the startup voltage of the terminal.

[0045] In the embodiment of the present disclosure, a terminal battery whose battery voltage before being connected to the charging device is less than the power-on voltage of the terminal is a dead battery to be activated.

[0046] In step S102, a power supply current is set for the terminal battery according to the charging type, and the terminal is initialized according to the power supply current to control the terminal to start up.

[0047] In the disclosed embodiment, the charging type used by the charging device to charge the target terminal is the charging protocol type supported by the charging device. After the terminal with a dead battery is connected to the charging device, the power management chip built into the terminal detects the charging type of the charging device and sets different power supply currents for the terminal battery based on the charging type of the charging device, such as: DCP: 1.5A, CDP: 1.5A, SDP: 0.5A. Different terminal initialization strategies are then specified based on different power supply currents to enable the terminal to complete initialization, ensure that the dead battery in the terminal can be activated, and ensure that the terminal is powered on during the pre-charging stage.

[0048] In the embodiments of the present disclosure, based on the different charging protocols supported by the charging device, the power management chip sets different power supply currents for the terminal battery. To ensure the normal initialization of the terminal, different terminal initialization strategies must be adopted when the power supply current provided by the terminal is greater than the current required for terminal initialization and when the power supply current provided by the terminal is less than the current required for terminal initialization. The following embodiments of the present disclosure illustrate the terminal initialization strategies corresponding to the charging protocols of different charging devices.

[0049] Figure 6 FIG. 1 is a flow chart showing a method for setting a corresponding power supply current for a terminal battery according to a charging type and turning on the terminal according to an exemplary embodiment. Figure 6 As shown, the method includes step S201, step S202A and step S202B.

[0050] In step S201, the charging type of the target terminal charged by the charging device is detected.

[0051] In step S202A, in response to the charging type being the first type, the power supply current of the terminal battery is set to the first power supply current, the terminal is initialized, and the terminal is turned on.

[0052] The first supply current is greater than or equal to a current threshold.

[0053] In step S202B, in response to the charging type of the charging device being the second type, the power supply current of the terminal battery is set to the second power supply current.

[0054] Among them, step S202A and step S202B are alternative execution modes.

[0055] In the embodiment of the present disclosure, the current threshold is the minimum current value for the terminal to be initialized smoothly. The terminal startup method provided by the present disclosure is targeted at a terminal with a high storage specification. The current required for initialization (i.e., the current threshold) is relatively high (e.g., 0.7A). When it is determined that the charging protocol type supported by the charging device is the first type with high charging power (e.g., DCP protocol or CDP protocol), the charging device has a higher charging power and can quickly charge the terminal battery. When the charging power of the charging device is high, the power management chip can set a higher power supply current (e.g., 1.5A) for the terminal battery to provide sufficient current for the terminal, which is greater than the current required for the terminal to be initialized. On the basis that this power supply current meets the requirements, the terminal can be initialized directly and the terminal can be pre-charged and powered on.

[0056] In the embodiment of the present disclosure, when it is determined that the charging protocol type supported by the charging device is the second type with low charging power (such as the SDP protocol), the charging device has a lower charging power, and the power management chip sets a lower power supply current (such as 0.5A) for the terminal battery.

[0057] In the embodiment of the present disclosure, the power management chip sets different power supply currents for the terminal battery based on the detected charging type of the charging device. The present disclosure identifies the charging type of the charging device and sets the terminal battery power supply current before the terminal is initialized, which avoids setting the terminal battery power supply current to a smaller default current value (such as 0.5A) when the charging power of the charging device meets the demand (such as: the actual corresponding power supply current is 1.5A), resulting in the power supply current not meeting the terminal initialization requirements (such as: less than 0.7A), resulting in terminal initialization failure and battery activation failure.

[0058] It is understandable that when the charging protocol type supported by the charging device is the second type of charging power (such as the SDP protocol), the power supply current that the terminal battery can provide is less than the current required for the terminal to initialize. In this case, in order to avoid the voltage of the terminal battery being reduced due to system loading, which in turn causes the terminal to restart due to undervoltage lockout, and ultimately causes the battery activation to fail, the terminal's demand for initialization current can be reduced so that the power supply current provided by the terminal battery can support terminal initialization, thereby completing battery activation. The following embodiments of the present disclosure illustrate a method for reducing the terminal's demand for initialization current so that the power supply current provided by the terminal battery can support terminal initialization.

[0059] Figure 7 FIG. 1 is a flow chart showing a method for performing terminal initialization according to a power supply current to control terminal startup according to an exemplary embodiment. Figure 7 As shown, the method includes steps S301 to S303.

[0060] In step S301, the power consumption of the terminal is reduced, and the power supply current required for starting up the terminal after the power consumption is reduced is determined.

[0061] In step S302, the initialization voltage of the terminal is determined according to the magnitude relationship between the power supply current required for starting up the terminal after power consumption reduction and the second power supply current.

[0062] In step S303, the current battery voltage of the terminal battery is monitored, and based on the magnitude relationship between the current battery voltage and the initialization voltage, the terminal is initialized and turned on.

[0063] It can be understood that the current required for terminal initialization is positively correlated with the power consumption of the terminal. Based on the correlation between the current required for terminal initialization and the terminal power consumption, the present invention reduces terminal initialization by reducing terminal power consumption when the power supply current of the terminal battery does not meet the terminal initialization requirement, thereby reducing the demand for power supply current for terminal initialization, so that the power supply current of the terminal battery meets the current required for terminal initialization or is close to the current required for terminal initialization.

[0064] In the disclosed embodiment, when the charging power of the charging device is low, resulting in the supply current of the terminal battery being lower than the current required for terminal initialization, the terminal power consumption is reduced, thereby reducing the demand for supply current for terminal initialization and ensuring smooth activation of the dead battery.

[0065] In the embodiment of the present disclosure, the power consumption of the terminal is affected by the core unit of the terminal that maintains normal operation of the terminal. The power consumption of the terminal can be reduced by adaptively reducing the power of the core unit of the terminal. The following embodiment of the present disclosure describes a method for reducing the power consumption of the terminal.

[0066] Figure 8 FIG. 1 is a flow chart showing a method for reducing power consumption of a terminal according to an exemplary embodiment. Figure 8 As shown, the method includes step S401 to step S402.

[0067] In step S401, in response to the charging type of the charging device being the second type, the power supply current of the terminal battery is set to the second power supply current.

[0068] In step S402, the central processing unit frequency of the terminal is adjusted to a first preset frequency, and the memory frequency of the terminal is adjusted to a second preset frequency.

[0069] In the disclosed embodiment, by reducing the frequency of the terminal's central processing unit (CPU) and double data rate synchronous dynamic random access memory (DDR, hereinafter referred to as memory), the power of the terminal processor and the power of the memory are reduced, thereby reducing the terminal power consumption, and further reducing the terminal initialization demand for the terminal battery power supply current. Under the premise of not increasing the terminal battery power supply current, the terminal initialization is completed and the dead battery is activated.

[0070] It is understandable that the first preset frequency after the processor is down-clocked and the second preset frequency after the memory is down-clocked can not only be the minimum frequency for maintaining the terminal standby, but also more gears can be set, each gear has a corresponding processor frequency and memory frequency. When adjusting the processor frequency and memory frequency, the frequency is adjusted from high to low, and the gears are adjusted one by one until the power supply current provided by the terminal battery meets the terminal initialization requirements. It is further understandable that the terminal startup speed is positively correlated with the processor frequency and memory frequency of the terminal. By setting multiple frequency gears, the terminal can be pre-charged and started with a relatively high processor frequency and memory frequency, thereby increasing the speed of terminal pre-charge startup.

[0071] In an embodiment of the present disclosure, after reducing the power consumption of the terminal and reducing the current requirement for terminal initialization, the power supply current of the terminal battery may still be unable to meet the current required for terminal initialization. Based on the magnitude relationship between the power supply current of the terminal battery after reducing the power consumption of the terminal and the current required for terminal initialization, the present disclosure resets the initialization voltage for terminal initialization for the terminal after the power consumption is reduced, and then controls the initialization and power-on of the terminal based on the relationship between the terminal voltage and the initialization voltage. The following embodiment of the present disclosure describes a method for determining the initialization voltage of a terminal after reducing power consumption.

[0072] Fig. 9 FIG. 1 is a flow chart showing a method for determining an initialization voltage of a terminal according to an exemplary embodiment. Fig. 9 As shown, the method includes step S501, step S502A and step S502B.

[0073] In step S501, the power supply current required for starting up the terminal after reducing power consumption is determined.

[0074] In step S502A, in response to the power supply current required for powering on the terminal after power consumption reduction being less than or equal to the second power supply current, the power-on voltage is determined as the initialization voltage.

[0075] In step S502B, in response to the power supply current required for starting up the terminal after reducing power consumption being greater than a current threshold, the current difference between the power supply current required for starting up the terminal and the second power supply current is determined, and a voltage increment is determined based on the current difference, and the sum of the voltage increment and the power-on voltage is determined as the initialization voltage.

[0076] Among them, step S502A and step S502B are alternative execution modes.

[0077] In the embodiment of the present disclosure, when the power supply current of the terminal battery meets the current required for initialization of the terminal after reducing power consumption, it indicates that the terminal can complete initialization without system loading, and a pre-set power-on voltage (for example: 2.7V) can be used as the initialization voltage of the terminal. When the power supply current of the terminal battery cannot meet the current required for initialization of the terminal after reducing power consumption, the power management chip of the terminal needs to complete the initialization of the terminal by reducing the battery voltage through system loading. In order to avoid the terminal battery voltage being too low after the reduction, causing the terminal to restart due to undervoltage lockout, the present disclosure sets an additional voltage increment (ΔV) on the basis of the preset power-on voltage of the terminal when the power supply current of the terminal battery cannot meet the current required for initialization of the terminal, and resets the initialization voltage for initializing the terminal based on the sum of the voltage increment and the pre-set power-on voltage (2.7V+ΔV).

[0078] In an embodiment of the present disclosure, when the power supply current of the terminal battery (e.g., 500mA) does not meet the current required for terminal initialization (e.g., 700mA), the terminal is initialized by reducing the terminal battery voltage (e.g., from 2.7V to 2.5V) through system loading. Among them, there is a corresponding relationship between the difference between the power supply current of the terminal battery and the current required for terminal initialization (e.g., 200mA) and the reduced value of the battery voltage (e.g., 0.2V). The present disclosure can store the corresponding relationship between the difference between the power supply current of the terminal battery and the current required for terminal initialization and the reduced value of the battery voltage when the system is loaded in the power management chip of the terminal in advance. When the power supply current of the terminal battery does not meet the current required for terminal initialization and the system is required to load, the voltage increment is determined based on the corresponding relationship between the above-mentioned current difference and the voltage reduction value, and the initialization voltage of the terminal is determined.

[0079] It is understandable that after the terminal is connected to the charging device, the battery voltage of the terminal battery will gradually increase over time. After the processor frequency reduction and memory frequency reduction are completed and the terminal initialization current demand is reduced, the battery voltage may not meet the power-on voltage demand, but after a period of time, the battery voltage will increase to meet the power-on voltage demand. Based on the increase of the battery voltage over time, it is necessary to synchronously monitor the battery voltage until the battery voltage meets the voltage requirement for the terminal to complete initialization. The following embodiments of the present disclosure describe methods for detecting the battery voltage, initializing the terminal, and turning on the terminal.

[0080] Fig.10 FIG. 1 is a flow chart showing a method for monitoring the current battery voltage of a terminal battery and starting the terminal based on the current battery voltage according to an exemplary embodiment. Fig.10 As shown, the method includes step S601 to step S602.

[0081] In step S601, the current battery voltage of the terminal battery is monitored at fixed time intervals, and the magnitude relationship between the current battery voltage and the initialization voltage of the terminal is determined.

[0082] In step S602, in response to the current battery voltage being greater than or equal to the initialization voltage, the terminal is initialized and turned on.

[0083] In the disclosed embodiment, a fixed time interval is preset, and after the processor frequency reduction and memory frequency reduction are completed, so that the power supply current provided by the terminal battery meets the current requirement of the terminal initialization, the power management chip detects the battery voltage at a preset time interval and compares it with the power-on voltage. Until it is detected that the battery voltage is greater than the power-on voltage, the terminal is initialized, the dead battery is activated, and the terminal is pre-charged and turned on. This avoids the battery voltage being lowered due to the system load during the terminal initialization process due to the battery voltage being lower than the charging voltage, resulting in undervoltage lockout and restart, which ultimately leads to the failure of terminal initialization.

[0084] In an exemplary embodiment of the present disclosure, a dead battery of a terminal with a storage specification of UFS4.0+1T and a startup voltage of 2.7V is activated to enable the terminal to be pre-charged and started. Fig.11 Flowchart of software strategy for activating dead battery in Fig.12As shown in the flowchart of the terminal startup method in FIG, the method includes the following steps: in response to the terminal battery being a dead battery, the terminal cannot be powered on due to low battery power, inserting a charger triggers power-on pre-charging, and the power management chip (Pmic) in the terminal initializes the power supply current (IBUS) of the terminal battery, and sets the power supply current to the default current of 500mA. The power management chip detects whether the battery voltage after connecting to the charger is greater than the power-on voltage of 2.7V. When the battery voltage is greater than the power-on voltage, the terminal is initialized (UFS4.0 initialization), the pre-charging icon is displayed, and the power-on pre-charging is performed. When the battery voltage is less than the power-on voltage, the charging type of the charging device (the charging protocol supported by the charging device) is detected based on the BC1.2 protocol, and different power supply currents (SDP: 500mA, CDP: 1500mA, DCP: 1500mA) are set for the terminal battery based on the different charging types of the charging device. After the battery current is set, the next step is performed after a delay of 600ms. In response to the charging type of the charging device being CDP or DCP, the terminal is initialized, the pre-charging icon is displayed, and the power-on pre-charging is performed. In response to the charging type of the charging device being SDP, the corresponding power supply current does not meet the requirements of terminal initialization, and the frequency of the terminal memory (DDR) and the central processing unit (CPU) is reduced so that the power supply current of the terminal battery meets the terminal initialization requirements. In response to the completion of the frequency reduction of the memory (DDR) and the central processing unit (CPU), the battery voltage is detected once every fixed time interval (1S) until the battery voltage is greater than the terminal startup voltage of 2.7V, the terminal is initialized, the pre-charge icon is displayed, and the startup pre-charge is performed. Through the present disclosure, after connecting the charging device, the problem that the dead battery in the terminal whose startup current is higher than the default power supply current of the battery cannot be activated is solved by a software strategy, and no additional hardware is required, which can save the internal space of the terminal and save costs.

In response to the power supply current required for the terminal to start up after the power consumption is reduced being greater than the second power supply current, the current difference between the power supply current required for the terminal to start up and the second power supply current is determined, and a voltage increment is determined according to the current difference, and the sum of the voltage increment and the power-on voltage is determined as the initialization voltage.
