Worry not my codeflying friend. An EV advertised with a 100 mile range as several of the more affordable choices have... has a range in reality that is closer to 50 miles. First there is the exaggeration factor which is typically 20% to 50% or more. Many of the specs have obviously been based on theory more than practice. (If we sell a car that weighs 4000 pounds with a 30kwh battery my calculator says it should be able to go 100 miles.)
Then if you charge to only 80-90% as recommended and discharge to only 20% you can see that you are going to get nowhere near the advertised range. Then there are the known issues this time of the year... if the batteries are allowed to get cold their capacity drops off dramatically. In hot weather you have to be careful in some cars that your batteries do not overheat which means limiting speed and acceleration and not using the air conditioner.
Except....that hasn’t been my experience at all for the last 6 years. I started at about 102 miles (almost as it was advertised) and six years later, I get about 80ish.
Cold range has been lower over the years for sure, sometimes forcing me to plug the car in every night during really cold spells for charging while I sleep. Hot temperatures even near 100 haven’t really had that much of an impact over the years. About 60 - 78 is the ideal temperature, which means most of the morning commutes are at ideal temperature in the South.
Also, EV’s are the opposite of ICE vehicles in that range is really quite good in slower traffic situations, and worse at high speeds when there is no traffic.
