6 FAQs about [Photovoltaic lead-acid battery active balancer]

What is passive and active battery balancing?

With 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.

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.

What is active balancing?

This circuit consists of a power resistor connected in series with a control MOSFET transistor. This method can be used for all types of batteries, but is effective for a small number of cells in series. The active balancing method is based on the active transport of the energy among the cells.

Why is auxiliary lead-acid battery used for balancing energy during discharge period?

What are the different types of battery charge balancing?

What is active cell balancing?

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.
