per cell charge controller
Hi if this isn't the right sub, mod please move.
Looking to buy or create a device to control balance charging, open / close the connection between each cell and the charge buss at a programmed voltage.
Say the target stop voltage is 3.47Vpc, while the charge source CV/Absorb target is set at 3.5V, and resting full is defined as 3.41.
As SoC climbs, the buss Voltage does as well, sensors measure voltage on each cell, when one detects 3.49V, that cell gets disconnected off the buss after X minutes.
If the isolated cell drops below 3.41V, the relay closes and charging resumes, again until 3.49V, holds for X minutes, then opens.
These are just examples, please no debates on the "big picture" use case, specific voltage / current numbers, cell chemistry / count / capacities etc, would like to keep the focus on a generalized "How To" implement this specific idea.
To be clear, the wiring harness and buss power supply issues are "a given" for purposes of this thread, also OT here.
Assuming nothing off the shelf will do this, suggestions as to components?
which type of controller PLC vs rPi vs Arduino?
suggestions as to get started learning how to get it done would be most appreciated.
