Almost all Victron systems use batteries.
Obviously the most important thing to watch in the short term is SoC (State of Charge) and to measure this we have the BMV's (battery monitor) or now built-in function in the MultiPlus and the CCGX to display.
But in the long term you also want to know the State of Health of your batteries. Why is this now being measured/calculated/predicted byt Victron equipment???
It's not that hard. I see 2 possibilities:
- Program an interval (every 3 or 6 months) where the battery is completely drained and then charged again automatically. The remaining capacity can be determined and displayed as a % SoH.
- Do regular calculations during cycles in every day use. For every cycle the voltage drop in that cycle in relation to the battery capacity used in that cycle can be measured and mapped. In this way a constanty updated indication of % SoH can be calculated.
It would be good to be able to reset the SoH calculations when a new battery is installed. Or even the SoH status of 2 sets of batteries can be stored, in case a battery is changed back.
I think it would be very useful to have an indication of SoH status of the batteries (and maybe even a prediction of when the batteries would reach a SoH of 80% capacity, when they are usually replaced. End users then know how the use of their batteries is affecting their lifespan and can plan a replacement moment, which avoids surprises.
