Free QuoteWith passive and active cell balancing, each cell in the battery stack is monitored to maintain a healthy battery state of charge (SoC). This extends battery cycle life and provides an added layer of protection by preventing damage to a battery cell due to deep discharging over overcharging.
Traditionally, lead acid batteries have been able to "self-balance" using a combination of appropriate absorption charge setpoints with periodic equalization maintenance charging. This characteristic of lead acid batteries is enabled by a secondary electrolysis (hydrogen producing) reaction within the electrolyte of the batteries.
One of the prime functions of this system is to provide the necessary monitoring and control to protect the cells from situations outside of normal operating conditions. There are two main methods for battery cell charge balancing: passive and active balancing.
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.
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.
This characteristic of lead acid batteries is enabled by a secondary electrolysis (hydrogen producing) reaction within the electrolyte of the batteries.
