Hey Thank You! That would be amazing!...I have been making & experimenting with Batt-Bridges recently.
As you probably, already know Batt-Bridges are voltage specific.
What is the voltage of the battery packs that you need the (6) Batt-Bridges for?
I may be able to make a few for you.![]()
Hey Thank You! That would be amazing!...
So my setup looks like this: I have my Bradley EV loaded with Chevy Volt Lithium batteries. Each Volt module is 12s. I have sets of two modules in series, for 24s, which yields a max voltage of 100v (24 x 4.1xx) - and a min voltage of 72v @ 3v/cell.
I have 6 of these (24s, 100v) strings running in parallel.
Since each string has two modules in series, it would be easy to connect one bridge to the center of each string.
And this is why I'm wanting 6 Bridges.
Not sure what color LED's you have, but I was looking at bright RED / BLUE (Blue in Center, Red indicating imbalance)
This because I am Red / Green colorblind... and also I like blue.
Well if you are into it I would be very grateful... anything I could do for you in exchange? I make some nice cabinet / door handles in my woodshop (crafted from Manzanita, our local, beautiful, curvaceous tree)... or??$?
thanks again for this possibility!
That's awesome you are familiar and working with Volt Packs too. Yes as you say, I suppose they are about 90v nominal in my setup (running two modules in series for 24s). I just think of them in terms of the max charge voltage (about 100v).A Bradley loaded with 2kWh Chevy Volt battery packs, that's great!
...those are the ones, I have been making Batt-Bridges (BPBM) Battery Pack Balance Monitors for.
Those 2 kWh Volt packs are ~44.4V -45V nominal
...so, you need BPBM's to monitor ~90V battery packs?
I have been color coding my BPBM's
...yellow LED's for 24V
...red LED's for 48V
...so, ya, blue LED's for 90V works for me
What are your installation & use plans?
1.do you want to hard wire the (6) BPBM's right on to the battery packs?
(like for, quick checks before trips, before charging & periodic monitoring)
2.do you want the (6) BPBM's mounted to the dash & hard wired to the battery packs for constant monitoring?
3...or (as an option) could you possibly use just (1) mobile unit, a "Spot Checker" I call it?
like this: https://www.youtube.com/watch?v=I8TX8guUsM4
...to manually check your battery packs individually?
(to know your packs are in balance before driving)
(&/or to check for cell imbalances before charging)
* From my research, these Chevy Volt packs are of good quality & well engineered/built.
...from reports from users, they seem to stay pretty well balanced
...so, periodic checking, especially before charging (may) be OK in this situation
