Even in the colder weather now, I'd be getting 400+ km on a full charge in my BEV (Mustang Mach e). But I only charge once a week (Fri night), to 80% to help with battery life; costs about $3 per week to get an extra 200-300km.
Pros: 400+ km on full charge
Vehicle:
Ford Mustang

Cons: factory batteries suck
