a connection module 13 for charging the battery cell 11 through the charging circuit 30 and the protection board 12;
and the protection board 12 is used for controlling the charging parameters of the battery cell 11.
In the embodiment of the present disclosure, the protection board 12 of the battery is bent, so that the occupied space of the protection board 12 is reduced, and therefore, the occupied space of the battery core is increased, the capacity of the battery is improved, and the service life of the battery is prolonged without changing the overall size of the battery.
Introduction of the protective plate 12: the protection board 12 of the battery 10 has a control circuit, and the control circuit can control parameters such as charging current and charging voltage of the battery cell 11. And when the abnormal conditions such as overvoltage, overcurrent, high temperature, low temperature, short circuit and the like occur in the charging process of the battery cell 11, the protection board 12 automatically disconnects the control circuit to stop charging the battery cell 11, thereby protecting the battery cell 11. In a possible implementation manner, when the charging voltage is greater than a certain threshold voltage, the protection board 12 opens the control circuit, and the battery cell 11 stops charging. The first threshold voltage may be set and changed as needed, for example, the first threshold voltage may be set to 10V, and when the charging voltage is greater than 10V, the protection board 12 disconnects the control circuit, and the battery cell 11 stops charging.
Overcurrent protection: when the charging current is greater than a certain threshold current, the protection board 12 disconnects the control circuit, and the battery cell 11 stops charging. The first threshold current may be set and changed as needed, for example, the first threshold current may be set to be 15A, and when the charging voltage is greater than 15A, the protection board 12 disconnects the control circuit, and the battery cell 11 stops charging.
Temperature anomaly protection: when the temperature of the battery cell 11 is greater than the first temperature threshold value or less than the second temperature threshold value, the protection board 12 disconnects the control circuit, and the battery cell 11 stops charging. Wherein, the first temperature threshold and the second temperature threshold can be set and changed according to the requirement, for example, the first temperature threshold can be set to be 75 ℃, and the first temperature threshold is-20 ℃; when the temperature of the battery cell 11 is greater than 75 ℃ or the temperature of the battery cell 11 is less than 20 ℃, the protection board 12 disconnects the control circuit, and the battery cell 11 stops charging.

The first circuit board 121 is a PCB, and the second circuit board 122 is an FPC; the FPC is jointed with the PCB, the extending part of the FPC, which is not jointed with the PCB, is bent along the direction parallel to the appointed edge, and the bent FPC is n-shaped; one end of the connection module 13 is connected with the extension part, and the other end of the connection module 13 is connected with the charging circuit 30 of the electronic device; the PCB is used for controlling the charging parameters of the battery cell 11; FPC for connecting the PCB with the charging circuit 30 of the electronic device.

The PCB is a double-sided board, one end of the FPC is arranged inside the PCB and connected through welding, a circuit of the PCB is connected with an internal circuit of the FPC, and one end of the FPC is attached to the inside of the PCB. The extending part of the FPC is bent along the direction parallel to the upper side edge of the battery cell 11, the bent FPC is n-shaped, and the extending part of the FPC is attached to the outer surface of the PBC, namely one end of the FPC is arranged in an interlayer of the PCB; the other end of the FPC is attached to the outer surface of the PBC after being bent.
In another possible implementation, referring to fig. 7, the FPC is disposed on the surface of the PCB, and the extended portion of the FPC is bent in a direction parallel to the designated edge and then attached to the surface of the FPC.

Moreover, the extending portion of the FPC is bent in the direction parallel to the specified side, so that the occupied space of the protection board 12 as a whole is not increased.
In another possible implementation, the extension of the FPC is the same size as the PCB.
In the embodiment of the present disclosure, when the size of the extending portion of the FPC is the same as the size of the PCB, the width of the FPC can be increased to the maximum extent, so as to reduce the internal resistance to the maximum extent, reduce the heat loss of the protection board 12, and optimize the effect of reducing the temperature rise of the battery 10.
In another possible implementation manner, the protection plate 12 may be bent once or multiple times, and in the embodiment of the present disclosure, the number of times the protection plate 12 is bent is not particularly limited, and may be set and modified as needed.

In one possible implementation, the material of the FPC may be a polyester film, a polyimide film, or a fluorinated ethylene propylene film. In the embodiment of the present disclosure, the material of the FPC is not particularly limited, and may be set and changed as needed.

The PCB is provided with a plurality of electronic elements which are connected through a lead to form a control circuit;
and a plurality of electronic components for forming the control circuit. When abnormal conditions such as overvoltage, overcurrent, high temperature, low temperature, short circuit and the like occur in the charging process of the battery cell 11, the control circuit of the protection board 12 can disconnect the circuit, so that the battery cell 11 stops charging, and the battery cell 11 is protected. In the normal charging process of the battery cell 11, the control circuit of the protection board 12 may also control parameters such as the charging current and the charging voltage of the battery cell 11, so as to protect the battery cell 11 in real time.
In another possible implementation, the protection plate 12 may be disposed on a side surface on the left side of the battery cell 11; the protection plate 12 is also arranged on the side surface on the right side of the battery cell 11; the protective plate 12 may also be provided on the side of the upper side of the cell 11; the protective plate 12 may also be provided at a side of the lower side of the battery cell 11. In the embodiment of the present disclosure, the positions of the protection plate 12 and the battery cell 11 are not particularly limited, and may be set and changed as needed.
Introduction of the cell 11: the battery cell 11 may be a lithium ion battery 10, a lithium iron battery 10, or a lead storage battery 10; when the battery cell 11 is the lithium ion battery 10, the battery cell may be an aluminum-clad battery cell 11, or may be a soft-package battery cell 11, in the embodiment of the present disclosure, the specific model of the battery cell 11 is not specifically limited, and may be set and changed as needed.
The size of the battery cell 11 varies according to the application scenario of the battery 10, for example, when the battery 10 is applied to a mobile phone device, the battery cell 11 is disposed in the mobile phone body 20 and should match the size of the mobile phone body 20. For example, the length of the mobile phone body 20 is 13cm, the width is 6cm, and the thickness is 1 cm; accordingly, the size of the battery cell 11 needs to be smaller than that of the body 20, and the length of the battery cell 11 may be set to 7cm, the width to 5cm, and the thickness to 0.5 cm. In the embodiment of the present disclosure, specific dimensions of the battery cell 11 are not specifically limited, and may be set and changed as needed.
Introduction of the connection module 13: one end of the connection module 13 is connected with the protection board 12, and the other end of the connection module 13 is connected with a charging circuit 30 of the electronic device;
in one possible implementation, the connection module 13 may be a flexible circuit board, and one end of the connection module 13 is connected to the protection board 12 by welding; the other end of the connection module 13 is provided with a soft and hard composite board, and is connected with the charging circuit 30 of the electronic device through the soft and hard composite board.
It should be noted that, when the first circuit board 121 is a PCB and the second circuit board 122 is an FPC, the whole PCB is bent through the FPC to attach the first PCB to the second PCB, and one end of the connection module 13 is connected to the outer surface of the second PCB by welding.
