In addition to acquiring the power supply state, one or more of parameters such as a power supply voltage, a power supply current, an output power, and the like may be acquired.

In step S820, if the first port module and the second port module are both in the external power supply state and the total output power of the battery for photography is higher than the first power threshold, the power of the ports in the second port module is controlled to be turned off so that the total output power of the battery for photography is lower than the first power threshold.

In this embodiment, by controlling the power-off of one or some of the second port modules when the total output power of the battery for photography exceeds the preset first power threshold, it is possible to effectively prevent the overload phenomenon of the battery for photography from occurring, avoid the risk of overheating, performance degradation, and even damage of the battery that may be caused by the excessive power, and simultaneously ensure that the photographic equipment powered by the first port module is preferentially supported by sufficient power.

In some alternative embodiments, when the ports in the second port module are controlled to be powered off, the ports in the second port module may be controlled to be powered off sequentially in a set order until the total output power of the battery for photography is lower than the first power threshold. The setting sequence comprises any one of the following modes, namely the sequence from late to early of external power supply starting time and the power-off sequence which is self-defined by a user.

For example, the second port module includes a DC8V output port and a DC12V output port, and the DC12V output port is firstly connected to an external device for supplying power, and then connected to the external device for supplying power after the DC8V output port, so that when the port in the second port module is controlled to be powered off, the DC8V output port can be controlled to be powered off first, and if the total output power of the battery for photography is still higher than the first power threshold, the DC12V output port is controlled to be powered off again.

Alternatively, the power-off sequence set by the user in a user-defined manner may be set according to actual needs, for example, a setting interface may be provided for the user, and then the user may adjust the power-off sequence of each port on the setting interface.

In some alternative embodiments, if the total output power of the battery for photography is still higher than the first power threshold after all the ports in the second port module are controlled to be powered off, the output current of the battery for photography is obtained, and when the output current is higher than the set current threshold, the battery for photography is controlled to stop externally supplying power.

In some alternative embodiments, if the first port module is not in the external power supply state, the second port module is in the external power supply state, and the total output power of the battery for photography is higher than the second power threshold, each port in the second port module is controlled to be powered off in a set sequence until the total output power of the battery for photography is lower than the second power threshold. The technical scheme of the embodiment can also effectively prevent the overload phenomenon of the battery for photography, and avoid the risks of overheat, performance degradation and even damage of the battery possibly caused by overlarge power.

According to the technical scheme, the battery state information can be sent to the battery control terminal in real time through the Bluetooth module and visually displayed on the battery control interface, so that a user can grasp the real-time state of the battery at any time, a shooting plan is reasonably arranged, and shooting interruption caused by insufficient battery electric quantity is avoided. Meanwhile, control instructions (such as charge start, charge stop, discharge mode adjustment and the like) triggered by a user on a battery control interface are rapidly transmitted to the photographic battery through the Bluetooth module, so that the accurate control of the charge and discharge process of the photographic battery is realized, and the control efficiency of the photographic battery is improved. The graphical display and the visual operation buttons on the battery control interface also reduce the use threshold, so that even a non-professional person can easily get on hand, and the portable operation mode not only improves the working efficiency of the user, but also enhances the use experience of the user.

In some alternative embodiments, the control instruction may include a power adjustment instruction for a designated port in the second port module, and the output power of the designated port may be controlled according to the power adjustment instruction. Therefore, specific requirements of different equipment or application scenes on power output can be met, and personalized settings aiming at different ports are realized.

And the accurate control of the output power of each port can be realized, and the fine management of the battery for photography is realized.

In some alternative embodiments, if a close instruction is received for a target port in the second port module, the target port is controlled to be powered off. The technical scheme of the embodiment enables the system to rapidly identify and respond to the closing instruction, and accurately control the power-off process of the appointed target port. Optionally, the user can control the closing instruction sent by the terminal or the related interface through the battery, and the power-off state of the port can be displayed on the control interface in real time, so that the intuitive operation feedback enhances the control feeling of the user and improves the overall use experience.

For the controllable ports, the power-off is started according to the principle that the power-off is started before the power-off is started after the power-off is inserted, if the output power is still more than 125W after the controllable ports are all disconnected, the battery can continue to supply power at the moment, if the output current exceeds 14A (the numerical value is only an example), the battery for shooting carries out overcurrent protection, and the BMS module cuts off the whole battery from outputting outside, and the battery for shooting is wholly powered off at the moment. In this case, the display module of the battery for photographing may continue to display, or may be turned off to stop displaying, and may resume the operation after the device is re-connected.

Assuming that the first port module does not supply power to the outside, but only the DC12V output port, the DC8V output port, the USB-A output port, the Type-C port 1 and the Type-C port 2 in the second port module supply power to the outside and output total power >110W (the numerical value is only an example), the display module of the battery for photography and/or the interface of the battery control terminal can indicate insufficient residual power, the power is about to start to be cut off, the power is cut off according to the principle of inserting and cutting off after cutting off, the power is cut off from the last inserted port until the output power is less than 110W, the indication information on the interface of the display module of the battery for photography and/or the battery control terminal disappears, and the battery work is restored to normal.

Optionally, in the embodiment of the present application, a user may control one or more parameters of closing, opening and output power of each port through a display module of the battery for photography and/or an interface of the battery control terminal, so that effective control of the battery for photography may be achieved, and on the premise of expanding a use scenario of the battery for photography, use safety and power supply efficiency of the battery for photography are improved.
