P3 charge index

[GtHbbrr]

Would it be possible to add the calculation of the P3 charging index (P3CI) from the charging data?

the formula is:

P3CI = real recharged range after 20 minutes of charging from SoC=10% / 300km

NB the grafana graph or table could show for example the best P3CI-values per outside temperature. Or just add highest value over time period to Charging stats dashboard

NB2 only DC fast chargers with minimum 20 minutes of charging past SoC 10% should be taken into account

NB3 for real recharged range I propose to use the real consumption from the last drive before the charging session the P3CI is calculated for.
