Active Battery Balancing. In active battery balancing, a charging current is intentionally routed between a high SOC cell and a lower SOC cell. This is done with an interconnection as in the passive case, but the charge is intentionally directed between specific cells rather than allowing the charge to balance naturally. Once the two chosen

There are two main methods for battery cell charge balancing: passive and active balancing. The natural method of passive balancing a string of cells in series can be used only for lead-acid and nickel-based batteries. These types of batteries can be brought into light overcharge conditions without permanent cell damage. When the overcharge is

It is worth noting that this method is particularly well-suited for nickel and lead-acid battery balancing circuits. These battery types are capable of handling overcharge conditions without incurring any damage. Switching
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:
The control circuitry is complex and a discrete implementation is large and costly. The LTC3305 lead acid battery balancer is currently the only active lead-acid balancer that enables individual batteries in a series-connected stack to be balanced to each other.
A Lead-Acid BMS is a system that manages the charge, discharge, and overall safety of lead-acid batteries. Its primary function is to monitor the battery’s condition and ensure it operates within safe parameters, ultimately extending the battery’s life and preventing failures.
In all the examples, two or more lead-acid batteries are connected in series. When a single lead-acid battery in the stack fails, all the lead-acid batteries in the series stack need to be replaced to maintain battery stack performance. This is a considerable expense.
Lead-acid batteries have been around for over 150 years and remain widely used due to their reliability, affordability, and robustness. These batteries are made up of lead plates submerged in sulfuric acid, and their energy storage capacity makes them ideal for high-current applications. There are three main types of lead-acid batteries:
Number of cells: The balancing system becomes more complex with the number of cells in the battery pack. Balancing method: Choose active and passive balancing techniques based on the application requirements. Balancing current: Determine the appropriate balancing current to achieve efficient equalization without compromising safety.
