[0066] The battery assembly is internally provided with multiple safety protection mechanisms such as overcharge protection, overdischarge protection, and short circuit protection, ensuring the safety of the battery during use.

[0067] When the voltage of a certain battery pack 3 is higher than the set overcharge protection voltage value, and this high voltage state lasts for more than the preset delay time, the overcharge protection function will start. At this time, it will cut off the charging circuit of the battery pack 3, stop further charging of the battery pack 3, and lock the battery pack 3 as an overcharged state. The total screen 11 displays that the battery pack 3 is abnormal. Once the voltage of the battery pack 3 decreases to below the set overcharge release voltage and remains for a certain time exceeding the preset delay, the overcharge protection will be released, and the battery pack 3 can resume normal charging. Preventing the battery pack 3 from being damaged due to overcharging, ensuring the safety and stability of the battery pack 3.

[0068] When the voltage of a certain battery pack 3 is lower than the set overdischarge protection voltage value, and the low voltage state lasts for more than the preset delay time, the overdischarge protection function will start. At this time, it will cut off the discharge circuit, stop further discharge of the battery pack 3, and lock the battery pack 3 as an overdischarged state. When the voltage of the battery pack 3 recovers to above the set overdischarge release voltage and remains for a certain time exceeding the preset delay, the overdischarge protection will be released, and the battery pack 3 can resume normal discharge. Preventing the battery pack 3 from being damaged due to overdischarge, prolonging the service life of the battery.

[0069] The short-circuit protection unit can monitor the current state of the detachable battery pack and individual battery packs 3. When the charging current or discharging current of the battery pack exceeds the preset threshold, and this overcurrent state lasts for more than a preset delay time, the short-circuit protection function will be activated. At this time, it will cut off the corresponding circuit (charging circuit or discharging circuit), stop charging or discharging the battery pack, and lock the battery pack in a short-circuit state. After a certain delay time, the overcurrent protection will be automatically released, and the battery pack can resume normal use. Preventing the battery pack from generating large current due to short circuit, thereby causing fire, explosion and other serious consequences, ensuring the safety of users and equipment.

[0070] In summary, the battery protection device inside the battery compartment provides comprehensive safety protection for the battery pack 3 and detachable battery pack through the joint action of the overcharge and overdischarge protection unit and the short-circuit protection unit. These protection mechanisms can effectively prevent safety problems caused by overcharging, overdischarging or short circuit of the battery pack 3, thereby prolonging the service life of the battery and improving the safety and reliability of the equipment.

[0071] The fan, as the main heat dissipation device, is connected with the battery pack 3 and the temperature sensor. When the temperature sensor detects that the temperature inside the shell 1 is too high, the fan is automatically started to dissipate heat, ensuring the stable operation of the battery assembly. The built-in heat dissipation device can effectively cope with the heat generated during the charging and discharging of the battery, preventing the battery from overheating and prolonging the service life of the battery, and improving the overall performance and stability of the photographic equipment. The combination of the fan and the temperature sensor can monitor the temperature inside the shell 1 in real time and automatically adjust the heat dissipation effect, ensuring the stability of the battery assembly under long-term use or high load. The air outlet 14 on the outer wall of the shell 1 is designed to facilitate the timely discharge of heat from the shell 1, forming good air convection and improving the heat dissipation efficiency.

[0072] The shell 1 is provided with an inverter socket 13, which converts the direct current of the battery pack 3 into alternating current output through the inverter unit, meeting the needs of different equipment for alternating current.

[0073] The outer wall of the shell 1 is provided with a total screen display 11 for displaying information such as the state, voltage, power, and abnormal state of the battery pack 3. The power, voltage, and charging and discharging state of the overall detachable battery assembly of the utility model are also displayed. These information helps the photographer to understand the power and use of the battery pack 3 in real time. A boost control unit is provided inside the assembly for adjusting the output voltage. In this way, the photographer can flexibly adjust according to the voltage requirements of different devices. The total screen display 11, switch assembly 12, inverter socket 13, and lighting unit 15 not only improve the functionality of the battery assembly, but also enhance the convenience of its operation. The total screen display 11 can display the battery state in real time, the switch assembly 12 can control the switching of the inverter socket 13 and the lighting unit 15, and the lighting unit 15 can provide additional light sources in the shooting environment, while providing convenience for users to operate in dark environments. The lighting unit 15 usually uses LED lamp beads as light sources, which have the advantages of high brightness, low energy consumption, long service life, etc.
