According to “Power security technology manual of the mining explode-proof (or Essence safety) type lithium ion battery”, the paper puts forward a kind solution of the power assembly and monitoring management system used in coal mine lithium ion (Li+) battery. Based on CAN bus communication, the paper adopts layer modular structure design, comes out with the hardware circuit and the software flow chart based on the finite state machine, achieves the comprehensive detection of Li+ battery temperature, voltage, and current, solves the problem of Li+ battery equilibrium management during grouping process, improves the performance and lifetime of Li+ battery, establishes the Li+ battery state observation matrix, through the nonlinear curve fitting, estimates the Li+ battery state of charge (SOC), and improves the accuracy and reliability of calculating the battery capacity. The system can be used as momentum power supply, start power supply, and reserved power supply to coal mine equipment and has good development prospect and broad application market.
