In the embodiment of the present application, specific positions of the first group of tabs 111b and the second group of tabs 111c protruding out of the cell unit 111a are not further limited.

In one embodiment, the cell unit 111a may include a wound positive electrode sheet, a wound negative electrode sheet, and a separator disposed between the positive electrode sheet and the negative electrode sheet.

As shown in fig. 3, in one embodiment, the electronic device further includes a first controller 160. The first controller 160 is connected to the external interface 120, the first discharging circuit 140, and the second discharging circuit 150, respectively. The first controller 160 is configured to control the first discharging circuit 140 to be turned on and the second discharging circuit 150 to be turned off when the external interface 120 is externally connected to the device to be charged.

The first controller 160 is also used to identify the type of device accessed to the external interface 120. The device type may include a charging type and a discharging type, wherein the charging type may be understood as an adapter that is used only for charging a battery, and does not have a function of storing electric energy. The discharging type is understood to be an electronic device capable of storing electric energy, such as a mobile terminal, such as a charger, a mobile power source, a bracelet, a mobile phone, and the like, which can charge a battery and also can receive the reverse charging function of the battery.

When the device type of the external charging device is a discharging type, it may be determined that the device connected to the external interface 120 is a device to be charged. When the external interface 120 is connected to the device to be charged, the first controller 160 may control the first discharging circuit 140 to be turned on and the second discharging circuit 150 to be turned off, so as to charge the device to be charged based on the battery unit 110 and the first discharging circuit 140, or control the second discharging circuit 150 to be turned on and the first discharging circuit 140 to be turned off, so as to supply power to the electronic device based on the battery unit 110 and the second discharging circuit 150.

In an embodiment, the first controller 160 is further configured to detect and obtain first power information of the battery unit 110 in the electronic device, and second power information of the device to be charged. Wherein, the first electric quantity information and the second electric quantity information can be understood as residual electric quantity.

When the first power information is greater than the first threshold and the second power information is less than the second threshold, the first controller 160 may control the first discharging circuit 140 to be turned on and the second discharging circuit 150 to be turned off, so that the battery unit 110 and the second discharging circuit 150 supply power to the device to be charged, that is, the battery unit 110 is in a reverse charging state, which may also be referred to as a discharging state. When the first power information is less than or equal to the first threshold and the second power information is greater than or equal to the second threshold, the first controller 160 may control the second discharging circuit 150 to be turned on and the first discharging circuit 140 to be turned off, so that the device to be charged charges the battery unit 110, and meanwhile, the electronic device may also be powered based on the battery unit 110 and the second discharging circuit 150.

It should be noted that the first electric quantity information and the second electric quantity information may be replaced by a voltage signal or a current signal.

As shown in fig. 4, in one embodiment, the electronic device further includes a second charging circuit 170. The second charging circuit 170 is connected to the second connection end 115 and the external interface 120, respectively. Specifically, the second charging circuit 170 is disposed adjacent to the motherboard 20, that is, the second charging circuit 170 and the second discharging circuit 150 are disposed adjacent to the motherboard 20. When the external interface 120 is connected to the adapter, the battery unit 110 can be charged based on the second charging circuit 170.

In an embodiment, the first controller 160 is further connected to the first charging circuit 130 and the second charging circuit 170, respectively. When the external interface 120 of the electronic device is connected to the external charging device, the first controller 160 may identify a charging mode of the external charging device. The charging mode comprises a normal mode and a fast mode.

It should be noted that the charging speed in the fast charging mode is greater than that in the normal mode. For example, the charging current in the fast charging mode is larger than that in the normal mode. For example, the fast charge mode may be understood as a large current charge mode, that is, the corresponding charge current may be higher than 2.5A and may reach 5-10A, and the fast charge mode is a direct charge mode, and the output voltage of the external charging device may be directly applied to both ends of the battery unit 110. The fast charging mode can also be a high-voltage fast charging mode, that is, the charging voltage of the fast charging mode is higher than the charging voltage of the normal mode, that is, the charging voltage of 9V, 15V, 20V, etc. can be generally provided, which is higher than the charging voltage (5V) of the normal mode, when the high-voltage fast charging mode is adopted to supply power to the electronic equipment, a voltage reduction circuit for voltage reduction processing needs to be added in the electronic equipment, and the voltage reduction circuit can reduce the charging voltage of the fast charging mode and then is suitable for the charging voltage for supplying power to the electronic equipment. The normal mode may be understood as a charging mode in which the rated output voltage is 5V and the rated output current is less than or equal to 2.5A.

In one embodiment, the USB signal in the external charging device is a differential signal, and the signal line is D +, D-, and the D + or D-of the external charging device is provided with an up-and-down fixed resistor. High-speed and low-speed equipment is defined in the USB1.0/1.1/2.0 protocol to meet the requirements of different conditions, for example, D + of the high-speed equipment is connected with a pull-up resistor of 1.5kohm, and D-is not connected; the opposite is true for low speed devices. When the external interface 120 is connected to an external charging device, the resistance of the fixed resistor on the D + or D-of the external charging device can be quickly identified, and then whether the external charging device is a quick charging adapter is determined. When the external charging equipment is a quick charging adapter, the corresponding charging mode is a quick charging mode; and if the external charging equipment is a common adapter, the corresponding charging mode is a common mode.

Optionally, when the interface module is connected to an external charging device, the interface module may perform bidirectional communication with an external adapter connected to the external interface 120, and by receiving an inquiry instruction sent by the external charging device, the inquiry instruction is used to inquire whether the charging control device starts the fast charging mode, and send a confirmation instruction to the external charging device according to the inquiry instruction, where the confirmation instruction is used to instruct the charging control device to agree to start the fast charging mode, so as to identify the charging mode of the external charging device.

When the charging mode is the fast charging mode, the first controller 160 may control the charging channel for connecting the battery unit 110 and the first charging circuit 130, so that the external charging device charges the battery unit 110 through the first charging circuit 130; when the charging mode is the normal mode, the first controller 160 can control the conduction between the battery unit 110 and the charging channel of the first charging circuit, so that the external charging device charges the battery unit 110 through the second charging circuit 170.

As shown in fig. 5, in one embodiment, the electronic device further includes a first connection module 180 and a second connection module 190. The first connection module 180 is respectively connected to the first charging circuit 130 and the first discharging circuit 140, and is configured to selectively connect or disconnect the battery unit 110 and the first connection terminal 113. The second connection module 190 is respectively connected to the second charging circuit 170 and the second discharging circuit 150, and is configured to selectively connect or disconnect the battery unit 110 and the second connection terminal 115.

In one embodiment, the first connection template includes a second controller and the second connection module 190 includes a third controller. The second controller is connected to the first charging circuit 130, the first discharging circuit 140, the first connection terminal 113, and the third controller, and is configured to identify a charging and discharging mode of the battery unit 110, select to connect or disconnect the first connection terminal 113 with or from the battery unit 110 according to the charging and discharging mode, and output a corresponding control command to the third controller according to the charging and discharging mode, so that the third controller selects to connect or disconnect the second connection terminal 115 with or from the battery unit 110. The third controller is respectively connected to the second discharge circuit 150, the second connection terminal 115, and the second controller, and is configured to identify a charge and discharge mode of the battery cell 110, select to turn on or off the connection between the second connection terminal 115 and the battery cell 110 according to the charge and discharge mode, and output a corresponding control instruction to the second controller according to the charge and discharge mode, so that the second controller selects to turn on or off the connection between the second connection terminal 115 and the battery cell 110.

For example, when the first charging circuit 130 is connected to the external adapter to charge the battery unit 110, the second controller in the first connection module 180 may recognize that the current charging/discharging state of the battery unit 110 is the charging state, select to connect the first connection terminal 113 to the battery unit 110, and output a corresponding control command to the third controller, so that the third controller disconnects the second connection terminal 115 from the battery unit 110, and further charges the battery unit 110 through the adapter. When the battery unit 110 supplies power to a module to be powered in the electronic device through the second discharging circuit 150, the third controller in the second connection module 190 may recognize that the current charging and discharging state of the battery unit 110 is a discharging state, select to connect the second connection terminal 115 with the battery unit 110, and output a corresponding control instruction to the second controller, so that the second controller disconnects the first connection terminal 113 from the battery unit 110, thereby supplying power to the module to be powered in the electronic device through the battery unit 110.

For example, when the external adapter of the second charging circuit 170 charges the battery unit 110, the third controller in the second connection module 190 may recognize that the current charging/discharging state of the battery unit 110 is the charging state, select to connect the second connection terminal 115 to the battery unit 110, and output a corresponding control instruction to the second controller, so that the second controller disconnects the first connection terminal 113 from the battery unit 110, and further charges the battery unit 110 through the adapter.

When the battery unit 110 supplies power to a module to be powered in the electronic device through the first discharging circuit 140, the second controller in the first connection module 180 may recognize that the current charge-discharge state of the battery unit 110 is a discharge state, select to turn on the connection between the first connection terminal 113 and the battery unit 110, and output a corresponding control instruction to the third controller, so that the third controller disconnects the connection between the second connection terminal 115 and the battery unit 110, thereby supplying power to the module to be powered in the electronic device through the battery unit 110.

In this embodiment, the charge and discharge states of the battery unit 110 can be identified by the second controller disposed in the first connection module 180 and the third controller disposed in the second connection module 190, so as to cooperate with each other for control, that is, when the first connection end 113 is connected to the first charging circuit 130 or the first discharging circuit 140, the second connection end 115 can be disconnected from the battery unit 110 by the third controller, or when the second connection end 115 is connected to the second charging circuit 170 or the second discharging circuit 150, the first connection end 113 can be disconnected from the battery unit 110 by the second controller. In this implementation, two different sides of the battery unit 110 can perform the charging and discharging operations, thereby greatly shortening the current path in the charging process and the discharging process, reducing the power consumption and heat generated by the current passing through the path, realizing high-power charging and discharging, further accelerating the charging speed, and greatly improving the charging and discharging power. Meanwhile, the charge and discharge port (the first connection terminal 113 and the second connection terminal 115) arrangement of the battery cell 110 is not limited, and the flexibility of the application of the battery cell 110 is improved.

In an embodiment, the first connection module 180 is further provided with a first protection circuit connected to the first charging circuit 130 and the first discharging circuit 140, respectively.
