Three common SoC monitoring methods – voltage correlation, current integration, and Impedance Track are discussed. State of charge of lead acid battery is the ratio of the remaining capacity RC to the battery capacity FCC . The FCC (Q) is the usable capacity at the current discharge rate and temperature.
R DC must be compensated for a discharge current and temperature. Texas Instruments uses the Impedance Track method to determine SoC of lead acid batteries . While current off, the OCV is measured, which is used to determine the SoC and to update Q MAX. When discharging, both discharge current and voltage are measured.
Implementing a Lead Acid BMS comes with numerous advantages, enhancing both performance and safety: Extended Battery Life: By preventing overcharging and deep discharges, a BMS can significantly extend the life of a lead-acid battery. This is especially important in applications like solar storage, where cycling is frequent.
In some systems, particularly those with large battery banks, active balancing is used to transfer energy from one cell to another in real-time, while passive balancing simply dissipates excess energy as heat. Implementing a Lead Acid BMS comes with numerous advantages, enhancing both performance and safety:
