For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0052] In recent years, with the development of the photography industry, the auxiliary equipment required for camcorders has increased significantly, including mobile phones, lighting equipment, monitors, follow focus devices, wireless image transmission systems, stabilizers, and microphones. Since these devices all require power, and to enable camcorder batteries to function as multiple devices, various types of power supply ports can be incorporated into the batteries themselves. These include standard D-Tap and V-port ports, as well as USB-A, Type-C, and DC ports. Therefore, effectively controlling these ports to ensure the safety and power efficiency of the camcorder batteries, which may need to power multiple types of devices, is a crucial technical challenge that needs to be addressed.

[0053] Based on the aforementioned technical problems, this application proposes a new photographic battery. Specifically, referring to FIG1, the photographic battery in this application includes: a battery module 100, a first port module 200, a second port module 300, and a Bluetooth module 400.

[0056] In some optional embodiments, referring to FIG2, the second port module 300 may include: a voltage conversion circuit 301, a reverse connection protection circuit 302, and a DC output port 303. The voltage conversion circuit 301 is electrically connected to the battery module 100 and is used to perform voltage conversion processing on the output voltage of the battery pack; the reverse connection protection circuit 302 is connected between the voltage conversion circuit 301 and the DC output port 303 to prevent the DC output port 303 from supplying voltage to the voltage conversion circuit 301; the DC output port 303 is used to connect external devices.

[0057] In the embodiment shown in Figure 2, by setting up a reverse connection protection circuit 302, it is ensured that only the battery module 100 can supply power to external devices through the DC output port 303. This prevents damage to the photographic battery caused by the power supply voltage being applied in reverse through the DC output port 303 if the user mistakenly connects it to a power source. Optionally, the external device can be a mobile phone, camcorder, photographic lighting equipment, laptop, monitor, follow focus device, wireless image transmission device, stabilizer, microphone, etc. In a specific implementation, the reverse connection protection circuit 302 can be a switching device with unidirectional conduction function, such as a diode.

[0058] In some optional embodiments, if the second port module 300 includes at least two DC output ports 303 and voltage conversion circuits 301 corresponding to each of the at least two DC output ports 303, then the at least two DC output ports 303 can be connected to different reverse connection protection circuits 302, and the different reverse connection protection circuits 303 can be connected to different voltage conversion circuits 301. That is, the embodiments of this application can have multiple circuit structures including the voltage conversion circuit 301, the reverse connection protection circuit 302, and the DC output ports 303 shown in FIG2.

[0059] In some optional embodiments, referring to FIG3, the battery module 100 may include, in addition to the battery pack 101, a BMS (Battery Management System) module 102 and a main control circuit 103.

[0062] It should be noted that the USB-A port 306 can be used to power external devices using the USB-A port 306, and the second port module 300 may have one or more USB-A ports 306. Optionally, the USB-A port 306 can also be used to charge the battery pack in the battery module 100. If the second port module 300 contains multiple USB-A ports 306, these multiple USB-A ports 306 can be connected to the same USB-A protocol module 305 or to different USB-A protocol modules 305. That is, if the second port module 300 contains multiple USB-A ports 306, the output voltage of these multiple USB-A ports 306 when powering external devices can be the same or different.

[0063] Optionally, the USB-A protocol module 305 manages and processes digital signals from external devices connected to the USB-A port 306, and the voltage conversion circuit 304 transforms the output voltage of the battery module 100 to a target output voltage and outputs the target output voltage to the USB-A port 306. After an external device is connected to the USB-A port 306, the USB-A protocol module 305 converts the electrical signals from the USB-A port 306 into digital signals that can be recognized and processed by a computer or other device, parses and processes the USB communication protocol, ensures normal data transmission and communication between devices, monitors errors during data transmission, corrects errors or provides error feedback as much as possible, and ensures that the data transmission rate conforms to the negotiation between the device and the host to achieve optimal transmission efficiency.

[0067] Optionally, the Type-C port 309 can be connected to an Emark identification module, which is electrically connected to the power processor 307.

[0070] In some optional embodiments, the photographic battery may also be provided with a button module, which is electrically connected to the battery module 100; wherein the button module is used to turn the display module on or off; and / or the button module is used to turn the photographic battery on or off to supply power to external devices.

[0071] It should be noted that the above embodiments can be implemented individually or in combination. For example, in the embodiments of this application, the second port module 300 may include one or more ports as described in the above embodiments, and the number of each type of port may be one or more. Specifically, in one embodiment of this application, as shown in FIG7, the first port module 200 of the photographic battery may include a D-Tap input / output port and a V-port input / output port; the second port module 300 may include: a DC12V output port, a DC8V output port, a USB-A output port, a Type-C port 1, and a Type-C port 2. It should be noted that the ports shown in FIG7 are only examples. In the implementation process, any type and number of ports can be set according to actual needs, and the output voltage of the ports can be set according to actual needs.

[0072] Referring to Figure 7, the DC12V voltage conversion circuit is connected to the DC12V output port via a reverse connection protection circuit, and the DC8V voltage conversion circuit is connected to the DC8V output port via a reverse connection protection circuit. Because a reverse connection protection circuit is provided between the DC8V output port and the DC8V voltage conversion circuit, and between the DC12V output port and the DC12V voltage conversion circuit, it ensures that power is only output to the DC output port and transmitted to the external load when the polarity is correct. If the user incorrectly connects the power adapter, the reverse connection protection circuit will prevent power from flowing and protect the device and power supply from damage, thereby improving the safety performance of the photographic battery.

[0073] Both the DC12V voltage conversion circuit and the DC8V voltage conversion circuit are connected to the main control circuit 103 and the BMS module 102. The DC8V voltage conversion circuit controls the output of 8V voltage to the DC8V output port to accommodate 8V external loads, such as cameras, 8V lamps, and digital products; the DC12V voltage conversion circuit controls the output of 12V voltage to the DC12V output port to accommodate 12V external loads, such as 12V lamps and digital products.

[0074] Referring to Figure 7, the USB-A voltage conversion circuit is electrically connected to the main control circuit 103, the BMS module 102, and the USB-A protocol processing module, respectively. The USB-A output port is electrically connected to the USB-A protocol processing module. The USB-A protocol processing module manages and processes the digital signals of the external load connected to the USB-A output port. The USB-A voltage conversion circuit transforms the output voltage of the battery pack 101 to the target output voltage and outputs the target output voltage to the USB-A output port. After the USB-A output port is connected to an external load, the USB-A protocol processing module converts the electrical signals from the USB-A output port into digital signals that can be recognized and processed by a computer or other device, parses and processes the USB communication protocol, ensures normal data transmission and communication between devices, monitors errors during data transmission, corrects errors or provides error feedback as much as possible, and ensures that the data transmission rate conforms to the negotiation between the device and the host to achieve optimal transmission efficiency.

[0075] Referring again to Figure 7, the DC-DC power processor 1 is electrically connected to the BMS module 102, the main control circuit 103, the DC-DC voltage conversion circuit 1, and the Emark identification module. The Type-C port 1 is electrically connected to both the DC-DC voltage conversion circuit 1 and the Emark identification module. The DC-DC voltage conversion circuit 1 transforms the output voltage of the battery pack 101 to the target output voltage and outputs the target output voltage to the Type-C port 1. The Emark identification module detects and identifies external devices connected to the Type-C port 1 and determines their power requirements. The DC-DC power processor 1, based on the Emark identification module's identification and confirmation of the external devices, controls the DC-DC voltage conversion circuit 1 to output the target output voltage. Specifically, when an external load is connected to the Type-C port 1, the Emark identification module detects and identifies the external device connected to the Type-C port 1, determines its power requirements, and outputs a digital signal to the DC-DC power processor 1. Upon receiving the signal, the DC-DC power processor 1 transmits a control signal to the DC-DC voltage conversion circuit 1, controlling the DC-DC voltage conversion circuit 1 to output the voltage required by the external device. As can be seen, the technical solution of this application embodiment can automatically identify the needs of external devices and output the corresponding voltage, effectively improving the output and input functions of Type-C port 1 and realizing the fast discharge function of Type-C port. At the same time, Type-C port 1 can not only charge devices such as mobile phones and laptops, but also charge battery pack 101.

[0076] Optionally, referring to FIG7, the photographic battery may also include a Type-C port 2, wherein the DC-DC power processor 2 is electrically connected to the BMS module 102, the main control circuit 103, and the DC-DC voltage conversion circuit 1, respectively, and the Type-C port 2 is electrically connected to the DC-DC voltage conversion circuit 1; the DC-DC voltage conversion circuit 2 is used to transform the output voltage of the battery pack 101 to the target output voltage and output the target output voltage to the Type-C port 2, thereby realizing the fast discharge function of the Type-C port 2. At the same time, the Type-C port 2 can not only charge devices such as mobile phones and laptops, but also charge the battery pack 101.

[0077] Referring to Figure 7, the D-Tap input / output port and the V-port input / output port are electrically connected to the BMS module 102. The D-Tap and V-port input / output ports primarily supply power to photographic equipment and lighting equipment. The BMS module 102 monitors the electrical parameters of the battery pack 101 and controls its input and output based on these parameters. When the electrical parameters of the battery pack 101 are abnormal, the connection to the external load is disconnected. When an external load is connected to the D-Tap and V-port input / output ports, under normal conditions, the BMS module 102 controls the output voltage of the battery pack 101 and outputs the voltage to the D-Tap and V-port input / output ports, thus supplying power to the external load.

[0078] Optionally, referring to FIG7, the photographic battery may also include a display module, which is electrically connected to the main control circuit 103 and is used to display the electrical parameter information of the battery pack 101 and each port. For example, it can display the charging and discharging status information of each port, as well as the battery pack 101's charge, voltage, current, power, and other information, so that users can better manage and use the battery and avoid running out of power or encountering battery health problems at critical moments.

[0079] Optionally, referring to FIG7, the photographic battery may further include a button module, which is electrically connected to the main control circuit 103 and used to control the switching on or off of the photographic battery, thus allowing the user to better manage and use the battery. Optionally, the button module may also turn the display module on or off, allowing the user to view or hide the battery status information at any time as needed.

[0080] Optionally, referring to FIG7, the photographic battery may further include a Bluetooth module 400. The Bluetooth module 400 is electrically connected to the main control circuit 103 and is used for communication with the battery control terminal. After the Bluetooth module 400 is connected to the battery control terminal, the battery control terminal can read information such as the battery's charge, voltage, current, temperature, and port voltage and current status, and can control the battery to turn on or off, as well as control each port, thereby realizing remote control of the photographic battery.

[0081] It should be noted that the photographic battery in this application embodiment can be a V-type battery or other types of batteries mainly used to power photographic equipment.

[0082] The control method for a photographic battery including a first port module and a second port module in this embodiment of the present application will be described in detail below with reference to FIG8. This control method for the photographic battery can be executed by the main control circuit in the photographic battery, or it can be executed by a battery control terminal communicatively connected to the photographic battery. Referring to FIG8, the control method for the photographic battery includes at least steps S810 to S820, which are described in detail below:

[0083] In step S810, the total output power of the camera battery and the power supply status of the first port module and the second port module are obtained.

[0084] In some optional embodiments, the power supply status of the first port module and the second port module can be obtained through electrical connection circuits between the respective ports included in the first port module and the second port module. Optionally, the power supply status may include whether it is in a power supply state. In addition to obtaining the power supply status, one or more parameters such as supply voltage, supply current, and output power may also be obtained.

[0085] In step S820, if both the first port module and the second port module are in an external power supply state, and the total output power of the photographic battery is higher than the first power threshold, then the port in the second port module is powered off so that the total output power of the photographic battery is lower than the first power threshold.

[0086] In this embodiment, by controlling one or more ports in the second port module to cut off power when the total output power of the photographic battery exceeds a preset first power threshold, the overload phenomenon of the photographic battery can be effectively prevented, avoiding the risk of battery overheating, performance degradation or even damage caused by excessive power. At the same time, it can ensure that photographic equipment powered by the first port module receives sufficient power support first.

[0087] In some optional embodiments, when the ports in the second port module are powered off, the ports in the second port module can be powered off sequentially according to a set order until the total output power of the photographic battery is lower than a first power threshold. This set order includes any of the following: an order from latest to earliest start time for external power supply, or a user-defined power-off order.

[0088] For example, the second port module includes a DC8V output port and a DC12V output port. The DC12V output port is connected to the external device for power supply first, and the DC8V output port is connected to the external device for power supply later. When controlling the power off of the ports in the second port module, the DC8V output port can be controlled to be powered off first. If the total output power of the camera battery is still higher than the first power threshold, then the DC12V output port can be controlled to be powered off.

[0089] Optionally, the power-off sequence can be set according to actual needs. For example, a settings interface can be provided to the user, allowing the user to adjust the power-off sequence of each port.

[0090] In some optional embodiments, if the total output power of the photographic battery is still higher than the first power threshold after all ports in the second port module are powered off, the output current of the photographic battery is acquired. When the output current exceeds a set current threshold, the photographic battery is controlled to stop supplying power. This embodiment effectively prevents overheating, damage, or even safety accidents that may occur if the photographic battery continues to operate under high current conditions. It further ensures the safety and stability of the photographic battery, reduces the risk of premature aging due to prolonged overload operation, extends battery life, and reduces the frequency and cost of battery replacement.

[0091] In some optional embodiments, if the first port module is not in an external power supply state, the second port module is in an external power supply state, and the total output power of the photographic battery is higher than a second power threshold, then the ports in the second port module are controlled to be powered off in a set sequence until the total output power of the photographic battery is lower than the second power threshold. This embodiment's technical solution can also effectively prevent the photographic battery from overloading, avoiding the risk of battery overheating, performance degradation, or even damage due to excessive power.

[0092] In some optional embodiments, the photographic battery also includes a display module. This display module presents the battery control interface corresponding to the photographic battery. The user can then receive power adjustment commands set by the user for a specific port in the second port module through the battery control interface, and control the output power of the specified port according to the power adjustment commands. This embodiment's technical solution allows users to adjust the power of a specified port in the second port module through an intuitive and easy-to-use battery control interface. This not only meets the specific power output requirements of different devices or application scenarios but also improves user experience satisfaction. Simultaneously, adjusting the port's output power ensures that connected devices operate within the optimal power range, avoiding energy waste and reducing the risk of device damage or performance degradation due to power mismatch. This is significant for extending battery life, protecting devices, and improving the overall system stability and reliability.

[0093] In some optional embodiments, the photographic battery is also equipped with a Bluetooth module, which is used to communicate with a battery control terminal. The battery control terminal displays a battery control interface corresponding to the photographic battery. The battery status information of the photographic battery can be sent to the battery control terminal through the Bluetooth module so that the battery control terminal can display the battery status information on the battery control interface. Then, the control module can receive control commands triggered by the user on the battery control interface to control the charging and discharging process of the photographic battery based on the control commands.

[0094] The technical solution described above enables the real-time transmission of battery status information to the battery control terminal via Bluetooth, displaying it intuitively on the battery control interface. This allows users to monitor the battery's real-time status at any time, thus enabling them to rationally plan their shooting schedules and avoid interruptions due to insufficient battery power. Simultaneously, control commands triggered by the user on the battery control interface (such as charging start, charging stop, and discharge mode adjustment) are quickly transmitted to the camera battery via Bluetooth, achieving precise control over the battery's charging and discharging process and improving battery control efficiency. Furthermore, the graphical display and intuitive operation buttons on the battery control interface lower the barrier to entry, allowing even non-professionals to easily get started. This portable operation method not only improves user efficiency but also enhances the user experience.

[0095] In some optional embodiments, the control commands described above may include power adjustment commands for a specified port in the second port module, which can then be used to control the output power of the specified port. This can meet the specific power output requirements of different devices or application scenarios and achieve personalized settings for different ports.

[0096] In some optional embodiments, the battery status information displayed in the battery control interface may include at least one of the following: remaining battery power of the photographic battery, remaining discharge time of the photographic battery, temperature of the photographic battery, attribute information of each port of the photographic battery, power supply status of each port of the photographic battery, abnormal alarm information of the photographic battery, controls corresponding to each port of the photographic battery, switch control of the photographic battery, status information display mode switching control, health status of the photographic battery, number of charge cycles of the photographic battery, number of discharge cycles of the photographic battery, remaining lifespan of the photographic battery, charging threshold of the photographic battery, and discharging threshold of the photographic battery.

[0097] In some optional embodiments, if a target port in the second port module is detected to have an output power exceeding a third power threshold, the target port is powered off. This embodiment effectively avoids the risk of device damage due to excessive port output power, which is crucial for protecting external devices connected to the port and the photographic battery itself, ensuring device safety and stability. Furthermore, it allows for precise control of the output power of each port, enabling refined management of the photographic battery.

[0098] In some optional embodiments, if a shutdown command is received for a target port in the second port module, the target port is powered off. This embodiment enables the system to quickly identify and respond to shutdown commands, precisely controlling the power-off process of the specified target port. Optionally, the user can issue shutdown commands through a battery control terminal or related interface, and the port's power-off status can be displayed in real-time on the control interface. This intuitive operational feedback enhances the user's sense of control and improves the overall user experience.

[0099] In a specific application scenario, referring to Figure 7, assuming the second port module includes a DC12V output port, a DC8V output port, a USB-A output port, Type-C port 1, and Type-C port 2, and these ports, along with the first port module, are all supplying power, with a total output power > 125W (this value is for example only), then the display module and / or battery control terminal interface of the photographic battery can display a message indicating insufficient remaining power and an impending power cut-off. The power cut-off follows the principle of disconnecting controllable ports first, then uncontrollable ports. For controllable ports: power cut-off begins with the last inserted port. If the output power is still > 125W after all controllable ports are disconnected, the battery can continue to supply power. If the output current exceeds 14A (this value is for example only), the photographic battery will activate overcurrent protection, and the BMS module will cut off the entire battery's external output, resulting in a complete power cut-off for the photographic battery. In this situation, the photographic battery's display module can continue displaying information or turn it off, and can resume operation after the device is reconnected.

[0100] Assuming the first port module does not supply power externally, and only the DC12V output port, DC8V output port, USB-A output port, Type-C port 1, and Type-C port 2 in the second port module supply power externally, and the total output power is greater than 110W (the value is only for example), then the display module and / or battery control terminal interface of the photographic battery can display a message indicating insufficient remaining power and that power-off will begin soon. Power-off will follow the principle of cutting off power first when the last port is inserted, starting from the last inserted port, until the output power is less than 110W. At this point, the message on the display module and / or battery control terminal interface of the photographic battery will disappear, and the battery will resume normal operation.

[0101] Optionally, in the embodiments of this application, the user can also control one or more parameters, such as the closing, opening, and output power of each port, through the display module of the photographic battery and / or the interface of the battery control terminal. This can achieve effective control of the photographic battery, and improve the safety and power supply efficiency of the photographic battery while expanding the application scenarios of the photographic battery.
