funny - chuckles.... just gotta....
Typical Day, my 30kWh bank is hitting Float by 13:00 hours. It trickles in 1 to 3 amps into the packs as the active balancers do their thing and get all the cells to <0.009V delta in all packs. The fridge or freezer kick on, and Float handles it and ups the Amps and the batteries are left alone. By 14:00 +/- all the battery packs will be static @ 3.415Vpc , not taking any charge or outputting anything UNLESS a Big Demand hits and Float cannot handle it, but immediately after, Float steps up and brings them back up "if they dropped".
Float is NOT forcing anything into the battery packs, it just allows them to be fully saturated to the target voltage I set (the top of the Working Voltage Range) and services anything called for by the devices in the house/shop.
CASE IN POINT: Got a new Washing Machine and was excited to try out this new High Efficiency machine (old one was a monster pig). Mid Day, Batts all sitting in float with a low delta and happy. So in goes a Load & on goes the machine \\YAY// and observing the Midnite Status Panel (software) it's still in float but hauling down 48A roughly from the panels, 0 to batteries and my lights are on in the house, the washer is humming along and the fridge kicks on and Float served it all... End of day as the sun starts to head for its nap, my Battery Bank finally starts to be used and it starts at 3.400Vpc per pack, with a Cell Delta <0.010 (my setting on BMS).
I've been at his quite some time and have done extreme tests including Hard Thrash Tests with Max Loading & Charging, even with different BMS' to STRESS THEM to the edge. I depend on my systems because I am quite Rural & Remote and "shit happens" so I leave nothing to chance if at all possible... to the extent that I have 3 ways to generate power, draw water, heat my home etc (It's an Ex Military Thing, triple redundacy - damned triplicate.... LOL)
I am SORRY TO SAY, but there is some Clear Buffoonery Posted into this thread that deserves nothing less than a good Beatch Slappery ! and I am BEING POLITE.
From the Whitepapers:
Charging a Pack with a CCCV charger and a BMS
Fully chanrging a Li-Ion battery pack with a CCCV (Constant Current / Constant Voltage) charger and a BMS requires three stages
- Full charge: charger is fully on (CC), until a cell reaches its maximum voltage
- Balance: charger goes off and on (CC), while BMS balances the cells, until all cells reach 100 % SOC
- Top off: charger stays on (CV), while the current is reduced exponentially down to 0
The Constant Voltage of the charger must be set to CV = number of cells in series x max cell voltage.
Wives Tales, along with Assumptions being turned into Conclusions and stated as fact only belong in the bottom of the Outhouse !
