Main functions of the BMS for lead acid battery include: monitoring battery thermal runaway, open circuit, string insulation, cell electrolyte leakage, CDF discharge transient characteristic, string voltage, charge/discharge current, float current, cell voltage, cell internal resistance, cell temperature, ambient temperature and intelligent balance and estimating SOC/SOH, etc. The device automatically alarms when any parameter exceeds the alarm threshold.
Battery status monitoring and early warning: the lead acid battery management system monitors cell voltage, cell temperature and cell internal resistance real time on-line. The active battery management system carries out intelligent analysis of the thermal runaway trend of the battery, and issues early warning in time to prevent the battery into thermal runaway and protect the battery pack effectively
Battery string status monitoring: the 12v lead acid battery management system collects string voltage, charge and discharge current. It can effectively monitor the CDF phenomenon, directly display the float current and ambient temperature, and the current state of the battery, as well as help estimate battery status of charge (SOC) and health (SOH) in a high-accuracy way.
