Hello there, Electric battery vehicles are at their most efficient when the battery is up to temperature and they aren’t at their most efficient doing short journeys with a cold battery. After 10 miles or so, depending on the ambient temperature, the efficiency improves greatly, so ignore the efficiency readings after short journeys with a cold battery. ICEs are exactly the same. Just live with the car and you’ll learn how it behaves. Happy motoring 🤞👍
Thats a new one on me. It does make sense though.
If your car is plugged in at home, pre-heat the car, that’ll warm up both battery and the car using the house power supply.

I'll try to give my honest opinion but am always open to learning.
