I took a trip from Germany to Italy over the alps with my EV with only 60 kWh of Battery. In reality the largest amount of delay I got due to other uncontrollable factors like a massive 2 hours traffic jam. in contrast to that I had like 1 20 minutes charging break and one 5 minutes to buy my esim that i forgot for switzerland. The 20 minute break i was gonna take anyways to take a piss and eat some food.
