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:
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.
Lead Acid Battery Defined: A lead acid battery is defined as a rechargeable storage device where electrical energy is transformed into chemical energy during charging, and vice versa during discharging.
The lead acid storage battery is formed by dipping lead peroxide plate and sponge lead plate in dilute sulfuric acid. A load is connected externally between these plates. In diluted sulfuric acid the molecules of the acid split into positive hydrogen ions (H +) and negative sulfate ions (SO 4 − −).
In vented, non-maintenance-free lead–acid battery systems gases evolving from the water decomposition escape though the provided venting system. An appropriate ventilation takes care that the gases are quickly removed and do not accumulate to a critical level. This is crucial in order to eliminate the risk of an explosion.
Under constant voltage charging of valve regulated lead–acid batteries (VRLA), especially after aging and water loss, there is the risk of a thermal runaway situation. Facilitated oxygen transport through the separator and the liquid film on the negative electrode can increase the exothermic oxygen reduction processes at the negative electrode.

Lead-Acid Batteries: The Cornerstone of Energy Storage
Lead-acid batteries have their origins in the 1850s, when the first useful lead-acid cell was created by French scientist Gaston Planté. Planté''s concept used lead plates submerged in an electrolyte of sulfuric acid, allowing for the reversible electrochemical processes required for energy storage.
