I’m seeking clarification on how the charging state is transitioned from OFF to ON please. Specifically if I want to delay recharging the battery until say 50% SOC. How do I configure that?
In the charging control logic ‘extra parameters’ section I see CV13 resume below min cell voltage (3.30) & QC5 resume below shunt soc% (99%) with a transition delay of 300 seconds.
Is this where it is set? Which setting takes precedence? Can I use just SOC and ignore cell voltage?
Or should I be looking at SoC% Hi cutout/resume QC1 & QC7 instead?
Why on earth would you wont to do that. ??
a description of your system would help as all the BMS can do is instruct the battery charger not to charge.
There could be a number of reasons for delaying the recharge process, such as waiting for a time of day when utility power is cheaper or waiting for solar sources to come online.
In my case I have two battery banks - bank 1 is charged from solar and bank 2 is charged from bank 1. I want to keep bank 1 fully charged overnight and am happy to draw on bank 2 down to a nominated limit (eg 50% SoC).
I’m controlling this now via Node-Red but would like to know what logic the BMS uses to re-enable the charging state flag.
