Should energy used while parked count in my EV running costs?
Trip displays and electricity bills can cover different activity. How should parked use be treated when comparing the amount paid with the distance driven?
EVVerity explains
A closer look
For the bill, purchased energy counts
If energy is bought for the car during the accounting period, include it in the charging bill even when it supports parked functions. Dividing the complete cost by distance gives an all-in charging cost per distance for that period, not just propulsion efficiency.
Keep the metric’s name clear
A trip-consumption reading may exclude some parked activity. Do not force it to match the bill without checking the boundary and starting and ending charge. Keep separate labels for driving consumption and purchased electricity per distance.
