6 Frequently Asked Questions about “Balancing of series lead-acid batteries”
What is the ltc3305 lead acid battery balancer?
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 a series-connected lead-acid battery?
Series-connected lead-acid batteries find extensive use in the UPS (uninterruptible power supply) industry to provide backup power when the mains power is lost. Golf carts and other industrial electric vehicles are typically powered by a stack of series-connected lead-acid batteries.
What happens if a lead-acid battery fails?
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.
How can a battery balancer prevent unbalance in the future?
To prevent unbalance in the future, as the batteries are aging, use a Battery Balancer. The battery balancer is wired into a system as indicated in the image on the right. It measures the battery bank voltage and also the individual battery voltages.
How does a battery balancing system work?
An efficient battery balancing solution requires a switch network that can be used to move charge from one battery to another to achieve a balanced battery stack. The control circuitry is complex and a discrete implementation is large and costly.
Do I have a problem balancing my battery?
Yes, you do have a problem. Series-connected batteries should be balanced, otherwise you always overcharge one of them and over-discharge the other. Neither is good for the battery life and you also get less cycle capacity. A balancing device. A search for "24v battery equalizer" will get you some ideas.
