Would be nice to have a chart with the Date:
select soc, soft.version, max(charge rate) from table group by soc, soft.version
to see if a software version is changing the charge rate.
Yes, I know there are many more things affacting the charge rate. But if there is enough data for a software version it will be a good aproximation.
Maybe It could be done for the personal car, to see your own curve and for the fleet, to compare different car types or soft.versions or what ever. :)
