Active cell balancing is a more complex balancing technique that redistributes charge between battery cells during the charge and discharge cycles, thereby increasing system run time by increasing the total useable charge in the battery stack, decreasing charge time compared with passive balancing, and decreasing heat generated while balancing.
Lead-Acid batteries ARE balance charged using a process known as "Equalization." The cells in the series string that have the highest charge are allow to be over-charged, and this in turn allows the lower cells in the string to fully charge as well.
Go from high charge to significant discharge without significant float time. This confirms what user 38367 mentions, that individual cell balancing would be beneficial for lead acid batteries in such remote area hybrid power systems using lead acid batteries.
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 are OK with a certain float charge current forever. Lithium batteries would be damaged that way. When a lithium battery is full, trying to charge it more will cause damage. Conversely, in a car the "12 V" lead-acid battery is usually just charged with a fixed voltage of about 13.6 V.
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.
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.
