Lead-carbon battery energy storage system for coal mine ventilator

In order to improve reliability of power supply and ensure safety production of coal mine, a lead-carbon battery energy storage system used as emergency power supply for coal mine ventilator was introduced, and system structure, grid access way, system functions, start and quit strategy were described. The system can provide one hour power supply to coal mine ventilator when there is a local grid failure, and guarantee regular operation and safety production for coal mine.
