My idea of a basic flying cell/pack balancing system...
It is kind of designed for my setup, needs to be able to handle high(er) currents.
I want it to havea bit intelligence build in, to detect low loads on the system so itknow when to startbalance (only at night?)
In my mind, the switching frequence has to be slow on a bigger battery, even very slow, something like 15min/step.
The idea is to get a Arduino cycle the packs, messure and log voltage, and connect the high and low cel in turns to a flying cell...
Currentsto and from the flying cell can be messured, if no current flows ==> balancing between static and flying packis done ==>next step....
Like to know if there is somebody doing this kind of balancing on a system in use? or is this not going to work and a big waste of time??
Planningto use relays because i like the clicking of them (and easy to isolate)
I have the Batrium BMS, so adding a few longmons is a option also, but that isway to easy... i wanne haveit complicated this time.....
