Energy saving control method and device of electronic device
[0001] The present application claims priority to the Chinese patent application No. 202411398106.1, filed on September 30, 2024, and entitled "Energy saving control method and device of electronic device", the whole content of which is incorporated herein by reference. TECHNICAL FIELD
[0002] The present application relates to the technical field of battery management, in particular to an energy saving control method and device of electronic device. BACKGROUND
[0003] Electronic devices provided with batteries usually need to be transported and stored for a long time before reaching the hands of users after being produced in the factory. Long-time storage of the batteries after over-discharge or emptying will cause damage to the batteries, such as inability to charge or only partial recovery even if charging, and significant capacity attenuation. In order to avoid long-time emptying of the batteries, a shipping mode is introduced. In the shipping mode, the battery stops supplying power to the load circuit, and after the electronic device is powered on, the shipping mode is exited, and the battery of the electronic device can supply power to the load circuit. Through the shipping mode, the loss of battery power during transportation and storage (such as long-time non-use by the user) is reduced, and the storage life of the battery is maximally prolonged. The current way of entering the shipping mode is to send a command to the whole machine at the last station of the production line before the electronic device is shipped, and the process is cumbersome. SUMMARY
[0004] Therefore, the present application provides an energy saving control method of electronic device to solve at least part of the above problems, and the disclosed technical solution is as follows:
[0005] In a first aspect, the application provides an energy-saving control method of an electronic device, applied to an electronic device comprising a first battery and a second battery, the first battery comprising a first battery cell and a first battery management chip, and the second battery comprising a second battery cell and a second battery management chip, the first battery cell being connected to a system board through a first charging and discharging channel, and the second battery cell being connected to the system board through a second charging and discharging channel; the method comprising: after the first battery management chip detects that the power consumption current of the first battery cell is less than a first current threshold and the maintaining time reaches a first preset time length, the first charging and discharging channel is closed and the first battery management chip enters a waiting mode; after the second battery management chip detects that the power consumption current of the second battery cell is less than a second current threshold and the maintaining time reaches a second preset time length, the second charging and discharging channel is closed, and the second preset time length is greater than the first preset time length; after the first battery management chip and the second battery management chip detect that the system board is powered off, the first battery management chip and the second battery management chip enter a shipping mode. In this way, the first battery management chip first closes the charging and discharging channel between the first battery and the system board and enters the waiting mode, and the second battery management chip then closes the charging and discharging channel between the second battery and the system board. After that, the first battery management chip and the second battery management chip determine that the charging and discharging channels of the two batteries have been closed after detecting that the system board is powered off, and enter the shipping mode (i.e., full sleep mode), thereby avoiding the phenomenon of mutual interference of at least two battery systems in the electronic device when the shipping mode is entered, and the at least two battery systems smoothly enter the shipping mode.
[0006] In a possible implementation manner of the first aspect, after the first battery management chip and the second battery management chip detect that the system board is powered off, the first battery management chip and the second battery management chip enter the shipping mode, comprising: after the second battery management chip closes the second charging and discharging channel and detects that a power-on signal is invalid, the second battery management chip enters the shipping mode, the power-on signal being generated by a power-on circuit, the power-on circuit outputting a valid power-on signal in the case that the electronic device is powered on or the system board is powered on, and the power-on circuit outputting an invalid power-on signal in the case that the system board is powered off; and the first battery management chip enters the waiting mode and enters the shipping mode after detecting that the power-on signal is invalid. It can be seen that the first battery management chip and the second battery management chip determine whether the system board is powered off, i.e., whether the charging and discharging channel between the battery and the system board is closed, by detecting the power-on signal output by the power-on circuit, and this way of detecting whether the charging and discharging channel is closed is simple and reliable.
[0007] In another possible implementation manner of the first aspect, after the first charging and discharging channel is closed and the waiting mode is entered, the method further comprises: the first battery management chip detects that the system board is powered on, and remains in the waiting mode. It can be seen that the first battery management chip determines that the second battery has not closed the charging and discharging channel after detecting that the system board is powered on, and continues to wait until all charging and discharging channels between the battery and the system board are closed.
[0008] In a possible implementation manner of the first aspect, the second battery management chip detecting that the system board is not powered on comprises: the second battery management chip determining that the system board is not powered on after the second battery management chip detects that the system board is not powered on after a third preset time period after the second battery management chip closes the second charging and discharging channel, and the third preset time period is less than the first preset time period. In this way, the second battery management chip detects whether the system board is powered off after the second battery management chip closes the second charging and discharging channel between the second battery and the system board and delays for a second preset time period, thereby improving the accuracy and reliability of the detection result.
[0009] In a possible implementation manner of the first aspect, after the second battery management chip closes the second charging and discharging channel, the method further comprises: after the second battery management chip detects that the system board is powered on, the second battery management chip opens the second charging and discharging channel. As can be seen, if the electronic device receives a start-up operation during the period in which the second battery management chip closes the second charging and discharging channel and detects whether the system board is powered on, at this time, the start-up signal changes from invalid to valid, the second battery management chip determines that the electronic device is started up after detecting that the start-up signal is valid, and opens the second charging and discharging channel to normally supply power to the system board to support the start-up. In other words, the second battery management chip detects that the electronic device is started up after closing the second charging and discharging channel, and immediately restores the second charging and discharging channel to normally supply power to the system board.
[0010] In a possible implementation manner of the first aspect, the electronic device further comprises a start-up interrupt circuit, an input end of the start-up interrupt circuit is connected to a start-up circuit, and an output end of the start-up interrupt circuit is connected to a signal input end of the first battery management chip and the second battery management chip, the start-up interrupt circuit generates a start-up interrupt signal when the electronic device is switched from powered off to powered on; after the first battery management chip and the second battery management chip detect that the system board is not powered on and enter the shipping mode, the method further comprises: after the first battery management chip receives the start-up interrupt signal, the first battery management chip exits the shipping mode and opens the first charging and discharging channel; and after the second battery management chip receives the start-up interrupt signal, the second battery management chip exits the shipping mode and opens the second charging and discharging channel. In this way, after the main battery management chip and the auxiliary battery management chip receive the start-up interrupt signal, the main battery management chip and the auxiliary battery management chip simultaneously open the charging and discharging channels corresponding to the main battery and the auxiliary battery, thereby ensuring that the main board and the auxiliary board in the system board are powered on at the same time, and avoiding the risk that the device initialization time sequence is uncontrollable due to the inconsistent power-on time sequence of the main board and the auxiliary board, thereby causing the electronic device to be unable to start up.
[0011] In a possible implementation of the first aspect, after the first battery management chip closes the first charging and discharging channel and enters the waiting mode, and before the second battery management chip closes the second charging and discharging channel, the method further includes: after the first battery management chip receives a first communication interrupt sent by the system board, the first battery management chip exits the waiting mode and opens the first charging and discharging channel. The first communication interrupt is generated and sent to the first battery management chip after the system board detects that the power-on signal is valid. In this way, after the secondary battery management chip enters the waiting mode, the secondary battery management chip can exit the waiting mode and enter the normal mode immediately after detecting the power-on operation, and the secondary battery can resume normal power supply to the system board.
[0012] In a second aspect, the present application also provides an electronic device, including a first battery, a second battery, and a system board. The first battery includes a first battery cell and a first battery management chip, and the first battery cell is connected to the system board through a first charging and discharging channel. The second battery includes a second battery cell and a second battery management chip, and the second battery cell is connected to the system board through a second charging and discharging channel. The first battery management chip is configured to close the first charging and discharging channel and enter a waiting mode after detecting that the power consumption current of the first battery cell is less than a first current threshold and maintaining the first current threshold for a first preset time length, and enter a shipping mode after detecting that the system board is powered off. The second battery management chip is configured to close the second charging and discharging channel after detecting that the power consumption current of the second battery cell is less than a second current threshold and maintaining the second current threshold for a second preset time length, and enter the shipping mode after detecting that the system board is powered off. The second preset time length is greater than the first preset time length.
[0013] In a possible implementation of the second aspect, the first battery management chip is configured to enter the shipping mode after detecting that the system board is powered off, including: the second battery management chip enters the shipping mode after closing the second charging and discharging channel and detecting that a power-on signal is invalid. The power-on signal is generated by a power-on circuit, and the power-on signal is valid in a case that the electronic device is powered on or the system board is powered on, and the power-on signal is invalid in a case that the system board is powered off. The first battery management chip is configured to enter the shipping mode after entering the waiting mode and detecting that the power-on signal is invalid.
[0014] In a possible implementation of the second aspect, after the first battery management chip closes the first charging and discharging channel and enters the waiting mode, the first battery management chip is further configured to maintain the waiting mode after detecting that the system board is powered on.
[0015] In a possible implementation of the second aspect, the second battery management chip detects that the system board is not powered on, and is specifically configured to: determine that the system board is not powered on after closing the second charging and discharging channel for a third preset time length and detecting that the power-on signal of the system board is invalid. The third preset time length is less than the first preset time length.
[0016] In a possible implementation manner of the second aspect, the second battery management chip further functions to: after the second charging and discharging channel is closed and it is detected that the system board is powered, the second charging and discharging channel is opened.
[0017] In a possible implementation manner of the second aspect, the electronic device further includes a power-on interrupt circuit, an input end of the power-on interrupt circuit is connected to the power-on circuit, an output end of the power-on interrupt circuit is connected to a signal input end of the first battery management chip and the second battery management chip, when the electronic device is switched from power-off to power-on, the power-on interrupt circuit is triggered to generate a power-on interrupt signal, the power-on circuit outputs a valid power-on signal in a case that the electronic device is powered on or the system board is powered, and the power-on circuit outputs an invalid power-on signal in a case that the system board is powered off; the first battery management chip further functions to, after the power-on interrupt signal is received, exit the shipping mode and open the first charging and discharging channel; and the second battery management chip further functions to, after the power-on interrupt signal is received, exit the shipping mode and open the second charging and discharging channel.

[0030] The terms "first", "second", and "third" and the like in the description and in the claims of the present application and the drawings are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are not intended to limit the embodiments to a given embodiment or implementation.
[0031] In the present application, the terms "exemplary" and "for example" are used to illustrate at least one example of the present application. Any embodiment or design scheme described as "exemplary" or "for example" in the present application should not be construed as being more preferred or advantageous than other embodiments or design schemes. In fact, the use of the terms "exemplary" and "for example" is intended to present related concepts in a concrete manner.
[0032] For the sake of clear and concise description of the following embodiments, a brief introduction of the related art is given first:
[0033] As mentioned above, at present, the electronic device is sent an instruction at the last station of the production line before leaving the factory to enter a shipping mode. The shipping mode is the lowest static current mode of the electronic device. In the electronic device, the battery is connected to multiple chips or circuits at the back stage, for example, a system board, which has a small standby current but will consume a considerable amount of battery power after a long time. The shipping mode is essentially disconnected from the battery and the system board at the back stage, which greatly reduces the loss of battery power. In order to solve the problem of complicated operation of the electronic device entering the shipping mode, the present application provides a solution that the battery management chip automatically detects that the power consumption current of the battery is below a preset value for a certain period of time, and automatically closes the charging and discharging channel between the battery and the load side, that is, automatically enters the shipping mode.
[0034] The inventors found in the process of researching the present application that in an electronic device including at least two battery systems, i.e., the electronic device includes at least two battery systems, each battery system includes a battery management chip and a battery, and the battery management chip is used to monitor and manage the state of the battery. Taking a double battery system as an example, when the two battery management chips in the double battery system simultaneously detect that the shipping mode entering condition is met, the shipping mode is entered. However, the two battery management chips independently detect the shipping mode entering condition and cannot obtain the state of the other party. If one battery management chip detects that the shipping mode entering condition is met, and the other battery management chip detects that the entering condition is not met, the shipping mode cannot be entered. For example, in the scenario that the load side (such as a system board) is powered (such as any battery powers it or is powered through a charger), the battery management chip does not allow the shipping mode to be entered, and since the master and slave battery management chips cannot perceive whether the system side is charged and powered or another battery is powered, the shipping mode will not be entered.
[0035] When the double battery system exits the shipping mode, the charging and discharging channels need to be opened at the same time, and the two battery management chips independently detect the shipping mode exiting condition. If the time difference is large, the power-on timing of the master board and the slave board on the system board side will be inconsistent, resulting in uncontrollable initialization timing and a risk of failure to boot.
[0036] To solve the above problems, the present application provides an energy-saving control scheme for an electronic device, the electronic device includes at least two battery systems, and a waiting mode can be added in any battery management chip in the double battery system of the electronic device. When the first battery management chip detects that the power consumption current of the battery is lower than the first preset value and maintains the state for the first preset time length, the charging and discharging channel of the first battery is closed and the waiting mode is entered. The second battery management chip detects that the power consumption current of the battery is lower than the second preset value and maintains the state for the second preset time length, and the charging and discharging channel of the second battery is closed. Further, after the first and second battery management chips both detect that the system board (i.e., the load of the first and second batteries) is powered off, it is determined that the charging and discharging channels of the two batteries have been closed, and the first and second battery management chips enter the shipping mode.
[0037] I. Enter the shipping mode
[0038] The following still takes an electronic device with a double battery system as an example to introduce the energy-saving control scheme for an electronic device provided by the present application.
[0039] FIG. 1 is a process schematic diagram of an electronic device entering a shipping mode according to an embodiment of the present application.
[0040] As shown in FIG. 1, the electronic device includes a master battery, a slave battery, a master battery management chip, a slave battery management chip, and a system board.
[0041] The main battery and the auxiliary battery are used to supply power to the system board. The system board can include a main board and an auxiliary board, which respectively carry electronic components for implementing different functions of the electronic device.
[0042] The battery management chip can be integrated in the battery pack or the battery package, and is used to control the charging and discharging process of the battery, and ensure that the battery works safely and efficiently. In the dual-battery system, the main battery management chip is mainly used to control the working process of the main battery, and the auxiliary battery management chip is mainly used to control the working process of the auxiliary battery.
[0043] In a possible implementation, the auxiliary battery management chip adds a waiting mode. When the electronic device is powered off, the power consumption current of the battery is reduced. When the auxiliary battery management chip detects that the current entering condition of the shipping mode (the power consumption current of the auxiliary battery is lower than a preset value and is maintained for a first preset time length) is met, the waiting mode is entered, that is, the charging and discharging channel of the auxiliary battery is closed, that is, the switch tube on the charging and discharging channel of the auxiliary battery is turned off.
[0044] When the main battery management chip detects that the power consumption current of the main battery is lower than a preset value and is maintained for a second preset time length, and the second preset time length is greater than the first preset time length, for example, the first preset time length is 120 hours, and the second preset time length is 121 hours, the charging and discharging channel of the main battery is closed.
[0045] In another possible implementation, the main battery management chip adds a waiting mode. In this scenario, the main battery management chip enters the waiting mode to close the charging and discharging channel of the main battery after detecting that the current entering condition of the shipping mode (that is, the power consumption current of the main battery is lower than a preset value and is maintained for a first preset time length) is met. The auxiliary battery management chip closes the charging and discharging channel of the auxiliary battery after detecting that the power consumption current of the load side is lower than a preset value and is maintained for a second preset time length.
[0046] The energy-saving control method of the electronic device will be described in detail below with reference to FIG. 2 and FIG. 3. FIG. 2 is a processing flow of an auxiliary battery management chip (for example, the auxiliary battery management chip) provided in an embodiment of the present application, and FIG. 3 is a processing flow of a main battery management chip (for example, the main battery management chip) provided in an embodiment of the present application.
[0047] The embodiment takes the auxiliary battery management chip adding a waiting mode as an example for description. In the scenario of the main battery management chip adding a waiting mode, the processing flow of the main battery management chip is the same as that of the auxiliary battery management chip in the embodiment. As shown in FIG. 2, the processing flow of the auxiliary battery management chip can include the following steps.
[0048] In S101, the auxiliary battery management chip detects that the power consumption current of the battery is lower than a preset value, and determines that the battery enters a sleep mode.
[0049] The preset value can be set according to actual needs, for example, a value in the range of 3mA-6mA. When the electronic device is powered off, the load reduces the power consumption current, and the power consumption current of the battery also decreases. When the secondary battery management chip detects that the power consumption current of the battery is lower than the preset value, it is determined that the battery enters the sleep state.
[0050] In some embodiments, the preset values of the power consumption currents corresponding to the primary and secondary battery management chips can be set to two different values, and the primary and secondary battery management chips can perform subsequent processing based on the respective preset values, thereby improving the accuracy of the control process.
[0051] S102, the secondary battery management chip performs sleep timing.
[0052] The battery management chip triggers the timer to start timing after detecting that the power consumption current of the battery is lower than the preset value, and stops timing when the timing duration reaches a first preset duration or an abnormality is detected.
[0053] S103, determining whether the sleep duration reaches the first preset duration; if yes, performing S104; if no, returning to perform S102.
[0054] The first preset duration can be set according to actual needs, for example, 120 hours, i.e., 5 days. In an exemplary embodiment, when the timer timing reaches the first preset duration, a preset signal is sent to the secondary battery management chip, and when the secondary battery management chip receives the preset signal sent by the timer, it is determined that the sleep duration reaches the first preset duration.
[0055] S104, the secondary battery management chip enters a waiting mode and closes the charging and discharging channel of the secondary battery.
[0056] In an exemplary embodiment, the battery and the load circuit are connected through a switch tube (also referred to as a charging and discharging switch tube), and the on / off state of the charging and discharging channel can be controlled by controlling the on / off state of the switch tube.
[0057] In this embodiment, when the secondary battery management chip detects that the sleep duration reaches the first preset duration, it triggers the control of the off of the charging and discharging switch tube of the secondary battery, i.e., the closing of the charging and discharging channel of the secondary battery, and enters the waiting mode at the same time. In the waiting mode, the secondary battery management chip waits for detection of the power failure of the system board side before entering the shipping mode (i.e., full sleep mode).
[0058] S105, the secondary battery management chip determines whether the current state is in the waiting mode.
[0059] If it is determined that the current state is in the waiting mode, S106 is performed; if it is determined that the current state is not in the waiting mode, S108 is continued to be performed.
[0060] In some embodiments, a standby mode identifier can be set, and if the battery management chip is currently in the standby mode, the standby mode identifier is a first preset value, such as "1". If the battery management chip is not currently in the standby mode, the standby mode identifier is a second preset value, such as "0". Further, the secondary battery management chip determines the current mode by reading the standby mode identifier, for example, when the standby mode identifier is "1", it is determined that the battery management chip is currently in the standby mode, and when the standby mode identifier is "0", it is determined that the battery management chip is not currently in the standby mode.
[0061] In S106, the secondary battery management chip determines whether the power-on signal is invalid. If yes, S107 is executed; if no, S105 is executed.
[0062] In the embodiments of the present application, the battery management chip determines whether the system board side is powered on by detecting the level state of the power-on signal. If the secondary battery management chip detects that the power-on signal is an invalid level signal (such as high level), it is determined that the system board side is not powered on, and it is further determined that the charging and discharging channels of the main battery, the secondary battery and the system board side have been closed. In this state, the secondary battery management chip can enter the shipping mode.
[0063] When the battery management chip detects that the power-on signal is a valid signal (such as low level), it is determined that the system board side is powered on, and it is further determined that the system board side is normally powered. In this state, the secondary battery management chip continues to wait, i.e., returns to S105, until the power-on signal is detected to be invalid to enter the shipping mode.
[0064] In S107, the secondary battery management chip confirms that the charging and discharging channels of the system board side have been closed and enters the shipping mode.
[0065] After the secondary battery management chip closes the charging and discharging channels of the battery and the system board side and enters the standby mode, it determines whether to enter the shipping mode by detecting whether the power-on signal is valid. When the secondary battery management chip detects that the power-on signal is an invalid signal (such as high level), it is confirmed that the charging and discharging channels of the system board side have been closed, and the shipping mode is entered.
[0066] In S108, the secondary battery management chip opens the charging and discharging channels of the secondary battery.
[0067] When the secondary battery management chip detects that it is not currently in the standby mode, the charging and discharging channels of the secondary battery are opened, i.e., the secondary battery resumes to supply power to the load side (the system board side). For example, after the electronic device is powered off and the secondary battery management chip enters the standby mode, the electronic device detects a power-on operation to turn on, at this time, the secondary battery management chip enters the running mode from the standby mode (the process of the secondary battery management chip exiting the standby mode will be described in detail below), in this scenario, the secondary battery management chip detects that it is not currently in the standby mode, and then opens the charging and discharging channels of the secondary battery.
[0068] As shown in FIG. 3, the process flow of the main battery management chip includes the following steps:
[0069] S201, the main battery management chip detects that the power consumption current of the main battery is lower than a set value, and determines that the main battery enters a sleep state.
[0070] S202, the main battery management chip records the sleep time.
[0071] The sleep time can be recorded by a timer. In an exemplary embodiment, when the main battery management chip detects that the power consumption current of the battery is lower than a preset value, the timer is triggered to start timing, and when it is detected that the power consumption current is greater than or equal to the preset current, the timer is triggered to stop timing. At this time, the time recorded by the timer is the duration of the sleep state of the battery.
[0072] In another exemplary embodiment, a preset signal is actively sent to the main battery management chip when the timing duration of the timer reaches a set duration, and the timing is stopped.
[0073] S203, the main battery management chip determines whether the sleep time reaches a second preset duration, and if yes, S204 is executed; otherwise, S202 is returned to be executed.
[0074] The main battery management chip determines whether the timing duration of the timer is greater than or equal to the second preset duration. The second preset duration is greater than the first preset duration, for example, the first preset duration is 120 hours, and the second preset duration is 121 hours.
[0075] S204, the main battery management chip closes the charging and discharging channel of the main battery.
[0076] The main battery management chip controls the closing of the charging and discharging channel of the main battery after detecting that the sleep time is greater than or equal to the second preset duration, for example, by controlling the switch tube on the charging and discharging channel to be turned off. The second preset duration is greater than the first preset duration, which can ensure that the main battery management chip closes the charging and discharging channel of the main battery, and the secondary battery management chip has already closed the charging and discharging channel of the secondary battery.
[0077] S205, the main battery management chip determines whether the power-on signal is an invalid level signal; if yes, S206 is executed; if no, S207 is executed.
[0078] In this embodiment, the main battery management chip determines whether the power-on signal is an invalid level signal after closing the charging and discharging channel of the main battery and delaying for a period of time (such as 10s). If the system board side is powered, the power-on signal is a valid level signal, such as low level. If the system board side is not powered, the power-on signal is an invalid level signal, such as high level.
[0079] S206, confirming that the charging and discharging channels are closed, and entering the shipping mode.
[0080] The main battery management chip determines that the power-on signal is an invalid signal, confirms that the charging and discharging channels on the system board side are closed, at this time, the main battery management chip enters the shipping mode, i.e. full sleep mode.
[0081] S207, opening the charging and discharging channels of the main battery.
[0082] After closing the charging and discharging channels, the electronic device detects the power-on operation in a period of time (such as 10s) for detecting whether the power-on signal is an invalid signal, the power-on circuit on the system board outputs a low-level power-on signal, and when the delay requirement (such as 10s) is met, the main battery management chip detects that the power-on signal is a low-level signal (i.e. the power-on signal is valid), enters the normal mode, and opens the charging and discharging channels of the main battery. That is, when the power-on signal is detected to be an invalid signal in S205, the action described in S207 is performed.
[0083] As can be seen from FIGS. 1-3, after the electronic device is powered off, the secondary battery management chip closes the charging and discharging channels of the secondary battery after detecting that the power consumption current is lower than the preset value and maintaining for a first preset time length; the main battery management chip closes the charging and discharging channels of the main battery after detecting that the power consumption current is lower than the preset value and maintaining for a second preset time length. During this period, if there is no power-on trigger signal (a signal triggered by the power-on operation), the power-on signals detected by the main and secondary battery management chips are high-level signals, i.e. the power-on signal is invalid, at this time, the main and secondary battery management chips enter the shipping mode, and wait for the power-on interrupt to be activated to exit the shipping mode and enter the normal running state.
[0084] The electronic device energy-saving control method provided by the embodiment includes the following steps: when the secondary battery management chip detects that the power consumption current of the battery is lower than a first preset value and maintains the first preset time length, the charging and discharging channel of the secondary battery is closed and the secondary battery enters a waiting mode; after detecting that the charging and discharging channel of the primary battery is closed, the primary battery management chip enters a shipping mode; after detecting that the power consumption current of the battery is lower than a second preset value and maintaining the second preset time length, the charging and discharging channel of the primary battery is closed; and after detecting that the start-up signal is invalid, the primary battery management chip and the secondary battery management chip enter a complete sleep mode, i.e., the shipping mode, and wait for the start-up interrupt to activate and exit the shipping mode. In this way, the preset time lengths of the sleep of the two battery systems are set to be different, the charging and discharging channel of the side with the shorter preset time length is closed first, the charging and discharging channel of the side with the longer preset time length is closed later, then the two battery management chips enter the shipping mode after detecting that the start-up signal is invalid, and wait for the start-up to activate and exit the shipping mode, thereby avoiding the mutual interference of at least two battery systems in the electronic device when entering the shipping mode, and successfully entering the shipping mode. The power loss of the electronic device during transportation or long-time placement is reduced, thereby prolonging the service life of the battery.
[0085] II. Exiting the shipping mode
[0086] The electronic device exits the shipping mode in the following two scenarios: one is the exit scenario of the electronic device that has already entered the shipping mode, and the primary battery management chip and the secondary battery management chip both enter the shipping mode; and the other scenario is that the secondary battery management chip exits when in the waiting mode.
[0087] 1. The primary battery management chip and the secondary battery management chip both enter the shipping mode and then exit
[0088] FIG. 4 is a schematic diagram of a battery management system of an electronic device according to an embodiment of the present application. As shown in FIG. 4, the battery management system of the embodiment is additionally provided with a start-up interrupt circuit, which is a hardware circuit and can be integrated on the system board.
[0089] The input end of the start-up interrupt circuit is connected to the output end of the start-up circuit, and the output end is connected to the primary battery management chip and the secondary battery management chip. The start-up interrupt circuit is used to generate a start-up interrupt and transmit the start-up interrupt to the primary battery management chip and the secondary battery management chip under the action of the effective start-up signal output by the start-up circuit.
[0090] The start-up circuit is used to generate a corresponding start-up signal according to the state of the electronic device. When the electronic device is started up (for example, the power is turned on or the charger is plugged in), the start-up circuit outputs an effective start-up signal, such as a low-level signal. After the system board of the electronic device is powered off, the start-up circuit outputs an ineffective start-up signal, such as a high-level signal. In addition, after the primary battery management chip and the secondary battery management chip enter the shipping mode, the primary battery and / or the secondary battery still provide power supply for the start-up circuit. In some embodiments, the start-up circuit can be integrated on the system board.
[0091] After the main and auxiliary battery management chips of the electronic device enter the shipping mode, the system board is powered off, the start-up circuit outputs a high level signal, and then the power key is pressed or the charger is plugged in. The start-up signal output by the start-up circuit is switched from high level to low level and transmitted to the start-up interrupt circuit. Under the action of the low level, the switch tube in the start-up interrupt circuit connected to the ground is turned on, the output end of the start-up interrupt circuit is pulled low to low level, that is, the output end of the start-up interrupt circuit is switched from high level to low level, that is, a falling edge signal is generated, which is transmitted to the main and auxiliary battery management chips as a start-up interrupt signal. After receiving the start-up interrupt signal, the main and auxiliary battery management chips exit the shipping mode and enter the normal mode.
[0092] In another embodiment of the present application, the start-up interrupt circuit can output a low level signal after the main and auxiliary battery management chips enter the shipping mode, and output a high level signal after the electronic device is started up, that is, the start-up interrupt circuit generates a rising edge start-up interrupt signal when the electronic device is started up. The specific type of the start-up interrupt signal is not specially limited in the present application.
[0093] For the auxiliary battery management chip, as shown in FIG. 5, the flow further includes the following steps after S107 of the embodiment shown in FIG. 2:
[0094] S109, after receiving the start-up interrupt signal, the auxiliary battery management chip opens the charging and discharging channel of the auxiliary battery.
[0095] As mentioned above, when the electronic device is switched from the shipping mode to the start-up state, the start-up interrupt circuit is switched from high level to low level, that is, a start-up interrupt signal is generated and transmitted to the main and auxiliary battery management chips. After receiving the start-up interrupt signal, the auxiliary battery management chip exits the shipping mode and enters the normal mode, that is, the charging and discharging channel of the auxiliary battery is opened to enable the electronic device to start up and run normally.
[0096] The start-up interrupt signal generated by the start-up interrupt circuit is transmitted to the main and auxiliary battery management chips, and after receiving the start-up interrupt signal, the main battery management chip exits the shipping mode and enters the normal mode, that is, the charging and discharging channel of the main battery is opened. As shown in FIG. 6, the embodiment further includes the following steps after S206 of the embodiment shown in FIG. 3:
[0097] S208, after receiving the start-up interrupt signal, the main battery management chip opens the charging and discharging channel of the main battery.
[0098] It can be seen that the embodiment adds a startup interrupt circuit in hardware. After the startup interrupt circuit receives the valid startup signal output by the startup circuit (the startup operation of the electronic device triggers the startup circuit on the system board to generate a valid startup signal), the startup interrupt signal is generated and transmitted to the main battery management chip and the auxiliary battery management chip. After the main battery management chip and the auxiliary battery management chip receive the startup interrupt signal, the corresponding charging and discharging channels of the main battery and the auxiliary battery are started at the same time, so that the main board and the auxiliary board in the system board are powered on at the same time, and the risk of uncontrolled device initialization timing and the risk of failure to start caused by inconsistent timing of the main board and the auxiliary board are avoided.
[0099] 2. Exiting from the standby mode of the auxiliary battery management chip
[0100] In the scenario that the auxiliary battery management chip is in the standby mode, the main battery management chip is in the normal mode, the charging and discharging channel of the auxiliary battery is in the closed state, and the charging and discharging channel of the main battery is in the open state to keep the system board side powered. In this scenario, the auxiliary battery management chip only needs to exit from the standby mode to the normal mode.
[0101] In addition, in the scenario that the auxiliary battery management chip is in the standby mode, the main battery keeps the system board side normally powered, that is, the system board is in a live state, and the startup signal output by the system board side remains at a low level. After the startup interrupt circuit receives the low-level startup signal, the output still remains at a low level, and a falling edge signal will not be generated, that is, the startup interrupt signal will not be generated. Therefore, the startup interrupt signal cannot be used to trigger the auxiliary battery management chip to exit from the standby mode to the normal mode.
[0102] Therefore, the process of making the auxiliary battery management chip exit from the standby mode provided by the embodiment of the present application is shown in FIG. 7. After S104 shown in FIG. 2, the embodiment further includes the following steps:
[0103] S110, after the auxiliary battery management chip in the standby mode receives the first communication interrupt, the auxiliary battery management chip exits from the standby mode and starts the charging and discharging channel of the auxiliary battery.
[0104] After the electronic device detects the startup operation and switches from the shutdown state to the startup, the auxiliary board receives the startup signal and initializes the auxiliary battery management chip first. Before the auxiliary battery management chip is initialized, the auxiliary board on the system board side sends a communication interrupt to the auxiliary battery management chip. When the auxiliary battery management chip receives the first communication interrupt sent by the system board side, the auxiliary battery management chip immediately exits from the standby mode and starts the charging and discharging channel of the auxiliary battery, thereby restoring the power supply of the system board side by the auxiliary battery.
[0105] In addition, in another scenario, the secondary battery management chip detects that the sleep duration of the secondary battery management chip reaches the first preset duration and enters the waiting mode, the primary battery management chip detects that the sleep duration of the primary battery management chip reaches the second preset duration and closes the charging and discharging channel of the primary battery, if the electronic device detects the power-on operation within a small delay (such as 10s) of closing the charging and discharging channel and waiting for the power-on signal, the power-on circuit outputs a low-level power-on signal, and when the delay requirement is met, the primary battery management chip detects that the power-on signal is a low-level signal, enters the normal mode, and opens the charging and discharging channel of the primary battery. At this time, the secondary battery management chip also detects that the power-on signal is a low-level signal, and continues to remain in the waiting mode until the first communication interruption from the system board side is received to exit the waiting mode and enter the normal mode, and the charging and discharging channel of the secondary battery is opened.
[0106] In the embodiment, in the scenario that the secondary battery management chip is in the waiting mode, the power-on operation is detected, and the secondary battery management chip needs to immediately exit the waiting mode and enter the normal mode. In this scenario, the secondary battery management chip immediately exits the waiting mode and enters the normal mode when receiving the first communication interruption from the system board side, and opens the charging and discharging channel of the secondary battery, so that the secondary battery normally supplies power to the system board side. The secondary battery management chip can immediately exit the waiting mode and enter the normal mode after the power-on operation is detected after the secondary battery management chip enters the waiting mode, and the secondary battery normally supplies power to the system board.
