How is the cost of a drive calculated?
But it should rather be calculated based on the costs of the last charge! (And even that would be a generalisation, if that charge didn't start at 0 %.)
s there someplace we can find totals of all drives rather than just a per drive cost?
The drive cost is determined by the kWh used in the drive multiplied by the kWh cost for home charging in the settings page.
