Let’s say you actually do the exact 20-80 charge, that’s 60kWh or 77% of the available battery. So multiply the 60 by the price and if you choose the wrong charger you’ll be around the £45.
That has thrown me mate but could be down to me having a really bad day 🙂
Enyak 80 – 82kWh gross 77kWh usuable, so 60% of the battery charged – 60*77/100 = 46KWh needed to charger from 20 to 80%?
