battery monitoring with opto-isolators
Posted: Sat Aug 08, 2009 4:36 am
Hello All,
I am new to the group and am a self-taught electronics hobbiest.
I am wanting to build an interface for my computer that would allow me to monitor and record my 12 batteries in my Electric Vehicle individually.
I want to be able to see each battery's voltage as well as full pack voltage (144vdc) and amps in and out.
I have read a bit about using opto-isolators for this purpose, but am looking for some guidance on component selection and layout. I also have another battery bank that is 288vdc that I will be taking on if the first interface works out ok.
Thanks, and forgive me if my first post is on the wrong forum.
