Embodiment 1

[0020] see figure 1 , in this embodiment, an explosion-proof mine 5G online backup power supply, including a battery system 1, a battery management system 2, a voltage conversion system 3, a temperature management system 4, a dehumidification system 5, an explosion-proof system 6 and a power management system System 7; voltage conversion system 3 includes an input voltage conversion module and an output voltage conversion module. The mine power supply is connected to the battery system 1 through the input voltage conversion module, the battery system 1 is connected to the 5G equipment through the output voltage conversion module, and the battery system 1 is connected to the battery The management system 2 and the power management system 7 are connected to the battery management system 2, the voltage conversion system 3, the temperature management system 4, the dehumidification system 5 and 5G equipment.

[0021] Specifically, the battery system 1 is mainly composed of lithium ...

Embodiment 2

[0024] In this embodiment, an explosion-proof mine 5G online backup power supply, the rated power of the backup power supply is 100W, and the backup time is 8 hours; the battery system 1 is composed of 13 pieces of 20AH sodium ion batteries; the input is AC, and the voltage is 127V. The input voltage conversion module is converted to 40V DC voltage to charge the battery, and the output voltage conversion module is converted to 12V DC voltage to supply power to the load and femtobase station; the temperature management system 4 mainly sets the voltage conversion system 3 close to the bottom of the explosion-proof cavity, and Apply heat-conducting glue to increase heat dissipation; temperature management system 4 mainly places a moisture-absorbing bag mixed with activated carbon and molecular sieve in the explosion-proof battery compartment to control the humidity in the battery cavity to less than 60%; power management system 7 includes battery charge and discharge management, ba...

Embodiment 3

[0026] In this embodiment, an explosion-proof mine-used 5G online backup power supply, the rated power of the backup power supply is 500W, and the backup time is 4 hours; the battery system 1 is composed of 13 pieces of 50AH lithium iron phosphate; the input is AC, the voltage is 220V, after The input voltage conversion module converts the DC voltage to 42V to charge the battery, and at the same time converts the output voltage conversion module to 48V DC voltage to supply power to the load pico base station; the temperature management system 4 mainly sets the voltage conversion system 3 close to the bottom of the explosion-proof cavity, and Apply heat-conducting glue to increase the heat dissipation effect. Due to the power increase, the chain connection between the input voltage conversion module and the battery BMS charging management system is increased. Once the input voltage conversion module exceeds 70°C, the battery charging system will be cut off within 100ms, and the t...
