In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a charging method according to an embodiment of the invention. The method is applied to a multi-battery device in which at least a first battery and a second battery can be placed, and may include:
step 101: acquiring the configuration condition of multi-battery equipment; the configuration condition comprises a charging configuration condition and a battery configuration condition, the charging configuration condition comprises a chargeable state and a non-chargeable state, and the battery configuration condition comprises a double-battery state and a single-battery state.
It is understood that the multi-battery device in the present embodiment may be a device capable of performing system power supply by using a plurality of batteries (e.g., a first battery and a second battery) disposed therein, such as a mobile terminal device and a wearable device. The multi-battery device in this embodiment may house at least a first battery and a second battery, e.g., the multi-battery device may be a dual-battery device capable of housing the first battery and the second battery; it may be a device capable of housing two or more batteries, such as a three-battery device capable of housing a first battery, a second battery, and a third battery. Specifically, the batteries that can be placed in the multi-battery device in this embodiment may include a built-in fixed battery and a detachable battery that can be installed or detached, for example, the first battery may be a fixed battery of the multi-battery device, and the second battery may be a detachable battery of the multi-battery device, that is, the second battery may be detachably connected to the multi-battery device.
The configuration conditions of the multi-battery device in this step may include a charging configuration condition whether a charger (such as a wireless charger or a wired charger) is connected and a battery configuration condition whether a detachable battery (such as a second battery) is inserted into the charger, that is, when a power interface of the multi-battery device is connected to the charger, the charging configuration condition may be a chargeable state capable of supplying power by using the connected charger; when the power interface of the multi-battery device is not connected with the charger, the charging configuration condition can be a non-chargeable state which cannot utilize the charger to supply power; when the multi-battery device is inserted and installed with the detachable battery, the battery configuration condition can be a double-battery state comprising a fixed battery and the detachable battery; when the multi-battery device is not inserted and installed with the detachable battery, the battery configuration condition can be a single battery state only containing the fixed battery.
Specifically, the specific manner in which the processor (such as the power management chip and the battery management module) acquires the configuration of the multi-battery device in this step may be set by a designer according to a practical scenario and a user requirement, for example, the method may be implemented in a manner the same as or similar to the charger detection method and the battery detection method in the prior art, which is not limited in this embodiment.
Step 102: acquiring electric quantity information of multi-battery equipment; the electric quantity information comprises the electric quantity of the first battery or the electric quantity of the first battery and the electric quantity of the second battery.
It should be noted that, in this embodiment, the power information of the multi-battery device may be power information of a battery configured in the multi-battery device, for example, when a second battery is not inserted into the multi-battery device (i.e., the battery is detachable), the power information may include power of the first battery; the power information may include a power of the first battery and a power of the second battery when the second battery is inserted into the multi-battery device.
Correspondingly, for the specific content of the electric quantity information of the multi-battery device in this embodiment, the specific content may be set by a designer, for example, the electric quantity information may specifically be voltage information, that is, the processor may detect voltage information of batteries (such as the first battery or the first battery and the second battery) configured in the multi-battery device; the charge information may also be battery charge in percentage form. The present embodiment does not set any limit to this.
Specifically, the specific manner in which the processor obtains the configuration condition of the multi-battery device in this step may be set by a designer according to a practical scenario and a user requirement, and if the specific manner is the same as or similar to the method for detecting the electric quantity in the prior art, this embodiment does not limit this.
Step 103: controlling the battery charging condition of the multi-battery equipment according to the configuration condition and the electric quantity information; wherein the battery charging condition comprises a first battery charging state, a second battery charging state and a dual battery charging state.
It can be understood that the battery charging condition in this step may be a charging condition of a battery configured in the multi-battery device, and in this embodiment, through setting a dual-battery charging state in the battery charging condition, the multi-battery device may simultaneously charge the first battery and the second battery when the first battery and the second battery are configured in the multi-battery device, so as to reduce a system shutdown condition in the battery switching process.
Specifically, the specific manner in which the processor controls the battery charging condition of the multi-battery device according to the configuration condition and the electric quantity information in this step may be set by a designer according to a practical scene and a user requirement, for example, the processor may control the battery charging condition of the multi-battery device only by using the configuration condition and the electric quantity information, and for example, when the multi-battery device is a dual-battery device, the processor may determine whether the charging configuration condition is a dual-battery state when the charging configuration condition is a chargeable state; if so, controlling the charging condition of the batteries to be a dual-battery charging state when the electric quantity of the first battery and the electric quantity of the second battery are both not full electric quantity (namely, the electric quantity is not full), and charging the first battery and the second battery by utilizing external power supply of multi-battery equipment (such as power supply of an accessed wired charger or a wireless charger); if not, when the electric quantity of the first battery is not full of electric quantity, the charging condition of the battery is controlled to be the charging state of the first battery, and the first battery is charged by utilizing external power supply. Accordingly, after the first battery and the second battery are charged, the method may further include: when the electric quantity of any battery is full of electric quantity, controlling the charging condition of the battery to be a first battery charging state or a second battery charging state, and charging the battery with the electric quantity not full of electric quantity; that is, the multi-battery device may charge the first battery and the second battery simultaneously when the charger is plugged in and the second battery is plugged in, until any one battery is fully charged, and charge the other battery which is not fully charged; when the charger is connected and the second battery is not inserted, the first battery is charged until the first battery is fully charged.
Correspondingly, the processor can judge whether the charging configuration condition is a double-battery state or not under the condition that the charging configuration condition is a chargeable state; if so, controlling the charging condition of the batteries to be a double-battery charging state when the electric quantity of the first battery and the electric quantity of the second battery are not full of electric quantity, and charging the first battery and the second battery by using external power supply of multi-battery equipment; if not, under the condition that the first battery is the power supply battery, and when the electric quantity of the first battery is not fully charged and the electric quantity of the second battery is not larger than the switching electric quantity threshold value, controlling the charging condition of the batteries to be a double-battery charging state, and charging the first battery and the second battery by utilizing external power supply. Accordingly, after the first battery and the second battery are charged, the method may further include: and when the electric quantity of the second battery is greater than the switching electric quantity threshold value, controlling the charging condition of the battery to be the charging state of the first battery, charging the first battery, and continuing to charge the second battery after the first battery is fully charged.
Furthermore, the processor of the multi-battery device can also control the battery charging condition of the multi-battery device according to the configuration condition, the electric quantity information and the system on-off condition of the multi-battery device; the system power-on and power-off condition comprises a system power-on state and a system power-off state. If the multi-battery device is a dual-battery device, the processor may determine whether the charging configuration is in a dual-battery state if the charging configuration is in a chargeable state when the system power-on/off state is in a system power-on state; if not, when the electric quantity of the first battery is not full of electric quantity, controlling the charging condition of the battery to be a first battery charging state, and charging the first battery by using external power supply of multi-battery equipment; if yes, when the electric quantity of the first battery is not full of electric quantity and the electric quantity of the second battery is not larger than a switching electric quantity threshold (such as a threshold in fig. 2), controlling the battery charging condition to be a double-battery charging state, and charging the first battery and the second battery by utilizing external power supply; wherein, the first battery is a power supply battery; the power supply battery is a battery for supplying system power to the multi-battery device, namely, the battery for supplying system power to the multi-battery device when the charging configuration condition is a non-chargeable state.
Correspondingly, under the condition that the system power-on and power-off condition is the system power-on state and the charging configuration condition is the chargeable state, if the charging configuration condition is the dual-battery state, the processor can control the battery charging condition to be the first battery charging state when the electric quantity of the first battery is not fully charged and the electric quantity of the second battery is greater than the switching electric quantity threshold value, and charge the first battery by utilizing external power supply; when the electric quantity of the first battery is charged to full electric quantity and the electric quantity of the second battery is not full electric quantity, the charging condition of the battery is controlled to be the charging state of the second battery, and the second battery is charged by utilizing external power supply. As shown in fig. 2 and 4, when the system of the multi-battery device is powered on and the system is powered by the battery 1# (i.e., the first battery), if the charger (i.e., the wired charger) is inserted for charging, the processor may detect whether the battery 2# (i.e., the second battery) is inserted; if the battery No. 2 is not available, only charging the battery No. 1; when the battery 2# exists, while charging the battery 1# (such as charging through a power management chip), judging whether the electric quantity of the battery 2# meets a threshold (namely, a switching electric quantity threshold), wherein the threshold is used for ensuring that the battery 2# still has enough electric quantity to ensure that the system normally continues the work before the battery is switched when the battery 1# is switched to the battery 2 #; if the electric quantity of the battery 2# reaches the threshold value, only the battery 1# is charged continuously until the battery 1# is fully charged, the battery 2# is switched, and the battery 2# is charged by the power management chip until the battery is fully charged; if the charge of the battery 2# is below the threshold, the battery 2# is charged through the battery management module (the charging action is performed synchronously with the charging of the battery 1#), until the charge of the battery 2# reaches the threshold, the charging action is stopped, and the charging is continued after the battery 1# is fully charged. The other function of the threshold setting can reduce the synchronous charging time of the two batteries as much as possible while ensuring the normal work of the system when the batteries 2 are switched, reduce the power consumption pressure of the charger, reduce the potential safety hazard, and ensure that the two batteries are only monitored by the main chip and the power management chip as much as possible in a starting state.
Correspondingly, the processor can judge whether the charging configuration condition is a double-battery state, namely whether the second battery is inserted and installed, under the condition that the system on-off condition is the system off state and the charging configuration condition is the chargeable state; if so, controlling the charging condition of the batteries to be a double-battery charging state when the electric quantity of the first battery and the electric quantity of the second battery are not full of electric quantity, and charging the first battery and the second battery by using external power supply of multi-battery equipment; if not, when the electric quantity of the first battery is not full of electric quantity, the charging condition of the battery is controlled to be the charging state of the first battery, and the first battery is charged by utilizing external power supply. As shown in fig. 3 and 4, in the case where the system of the multi-battery device is powered off and the charger is inserted, the processor may detect whether the battery 2# (i.e., the second battery) is inserted; if the battery 2# does not exist, only the battery 1# (i.e., the first battery) is charged, and after the battery 1# is fully charged, the battery 2# can be charged until fully charged after the battery 2# is inserted. If the battery 2# exists, the battery 1# and the battery 2# are charged synchronously, and the charging path is shown by a dotted line in fig. 4, because the charging action occurs in the system shutdown state, the charging of the battery 2# is controlled only by the battery management module (for example, the control module in the battery management module in fig. 5), but the battery 1# is still controlled by the power management chip of the system (the common system platforms all support shutdown charging, but only support one battery). The process can only judge whether the two batteries are fully charged without setting a threshold value, and the power consumption of the system is ignored because the system does not have any working process in the shutdown state, and the power consumption pressure of the charger is not large when the two batteries are charged simultaneously compared with the startup state.
It should be noted that, the specific control manner for controlling the battery charging condition of the multi-battery device by the processor is shown by taking the battery charging condition control of a dual-battery device as an example, and for the battery charging condition control of the multi-battery device capable of placing the first battery, the second battery and the other battery (such as the third battery), the charging control corresponding to the first battery (i.e., the fixed battery) and the second battery (i.e., the detachable battery) may be implemented in the same or similar manner according to the configuration types of the other batteries (such as the fixed battery or the detachable battery), which is not limited in this embodiment.
The charging method provided in this embodiment may be applied to a multi-battery device, that is, a processor of the multi-battery device may execute the method provided in this embodiment to charge a battery configured in the multi-battery device, and this embodiment does not limit the specific number and type of processors in the multi-battery device that execute the method provided in this embodiment, as shown in fig. 4, the processor may include a power management chip, a battery management module, and a main chip.
Specifically, the specific manner in which the multi-battery device charges the first battery and/or the second battery in this embodiment may be set by a designer, for example, when the multi-battery device charges the first battery or the second battery, the multi-battery device may charge the first battery or the second battery by using the power supply of the charger (such as a wired charger or a wireless charger) through the power management chip. When the multi-battery equipment charges the first battery and the second battery, the multi-battery equipment can charge the first battery by using the power supply of the charger through the power supply management chip and charge the second battery by using the power supply of the charger through the battery management module; as shown in fig. 4, the power of the charger connected to the power interface charges the first battery through the power interface → the power management chip → the battery switching module → the charging path of the battery 1# (i.e., the first battery), and simultaneously charges the second battery through the power interface → the battery management module → the charging path of the battery 2# (i.e., the second battery).
Correspondingly, as shown in fig. 5, the battery management module may include a control module, a power switch, a charging module 1# (i.e., a first charging module) and a charging module 2# (i.e., a second charging module); the power switch can be used for opening and closing a power supply passage of the power interface and the charging module 2#, and is controlled by the control module; the charging module 2# is used for charging the battery 2# (namely a second battery), setting charging related parameters of the battery 2#, and controlling the charging function to be switched on and off by the control module; the charging module 1# is used for charging the battery 1# by the battery 2# and is also controlled by the control module; the control module can comprise a judging mechanism of the power-on and power-off state, the control module controls the peripheral module through internal logic in the power-off state, the control module can not be controlled by the main chip, after the power-on state is started, the internal logic of the control module is started and can be controlled by the main chip, and meanwhile, the battery 1 and the battery 2 are communicated with the main chip to transmit battery information such as electric quantity.
In the embodiment of the invention, the battery charging condition of the multi-battery device is controlled according to the configuration condition and the electric quantity information, and the multi-battery device can simultaneously supply power to the first battery and the second battery by using the setting of the charging state of the double batteries, so that the shutdown condition of the system in the battery switching process is reduced, the user experience is improved, and the commercial purpose of the multi-battery scheme is realized.
Corresponding to the above method embodiment, the embodiment of the present invention further provides a charging device, and a charging device described below and a charging method described above may be referred to in correspondence.
