Electronic Circuit Design

Do you have a battery level indicator for a 24V Ni-Mh recharegeable battery source ? Prefer the display as a LED or LCD traveling bar graph.

Thanks for the effort and your effort.

I think the www.solorb.com is good. and the instrument looks good and simple to implement. Now I am studying the circuit of solorb

Battery Level Indicator


This circuit uses a LM339, a quad comparator. LM339 can work on single or dual supplies, it has a open collector output that can drive 15mA, low power consumption. The circuit is an untested design but it should work. I did it as many searches were made in my webpages with these keywords.

I was reading about some IC's from Maxim/ Dallas saying " Simple battery characterizer" for plotting a charging/ discharging cycles & graphs are available on computer for study I want to plot an extensive data of these batteries.

The Lead Acid Batteries are used in Automobiles and UPS - Uninterrupted Power Supplies. Battery Banks and Arrays are used in Home and Industrial Power Systems with Solar and Wind power charging too.

Chargers & Charging -- Battery Management

These batteries have survived many other types, for rugged high power usage, even beyond 100Kva. It is all the more important for us, to learn how to use them properly. Intelligent charge controllers and charge-discharge cycle regulating managers, will ensure a long lifespan for optimum cost-effective usage of this Electro-Chemical Wonder.

"While I was on a month long assignment in Washington DC in 1999, I read an article on battery management in the 1999 Ocean Navigator "Annual" issue that I thought was deeply flawed. The contributor, Chuck Husick, illustrated how he thought one should maintain and configure a marine battery system."
