Battery Management System (BMS) that designed to monitor 16s battery pack. The BMS offers protection and recovery to individual cell over/under voltage, pack over/under voltage, charge/discharge over current, high/low temperature and short circuit. And accurately calculates the SOC and SOH status. As well as keeps voltage balancing during charging and discharging. And could also monitors parameter settings and data through computer via RS485 interface. (Baud rate 19200. )
