Hi all,
Am trying to make an intelligent battery / inverter management software, i.e, it does the comms between the BMS and the Inverter and manage it all better than no comms between, including multiple BMS's, dynamic charge and discharge current limiting, and also want to include the peak/off peak tariff calculation so if you have low battery you can charge up on cheaper overnight electric.
What I need to know is a few things on the Lifepo4 batteries:
1. how to tell when the batteries are getting full, I've read that at a certain amps of the C rate you need to switch to CV,
2. what amount of C rate should the amp-age be for topping off after bulk charge, i.e after CC to CV.
3. what limit of C rate loading at what percentage of battery life left, i.e is it at 25% you should only use 10% of C rating to not drop them off to quick
4. any load compensation to cell voltages, i.e at 0.5 C load allow 100mv drop?
Anything else you think is good info would be welcome.
