VRM: More battery info (Cycle Count, avg. SoC)

Is there a chance the VRM could compute and show the "effective cycle count" of a battery in a shown timeframe - and/or total? Seeing this raw SoC is nice and informative, but in order to estimate % Lifetime left, there are some crucial infos missing.

A moving average SoC for the past 30/90/... days would also be helpful.

So showing something like:
300 Full Cycles eff.
85% SoC avg

would be helpful to observe aging of batteries at the monitored site.

Good suggestion about the cycles - I will pass it on.

For now though, you can still get arguably even better data than 'cycles' by exporting the kWh data from the Advanced tab, and calculating total transacted kWh.

This still requires a bit of excel work to make the totals, but it's good to explore. If we can think of some very useful ones, we might be able to convince a programmer to make them into an embedded VRM report.

The difference between Charge and Discharge done like this will this will also show you efficiency of the battery. Another useful way to determine how it's going in its life.


The average SOC is already shown on the dashboard display, as long as the time scale is appropriate, eg Last Year, shows Average SOC for each month.
