New electric vehicle drivers need to understand how elastic the concept of charging and range are with respect to how the car is driven. This is much more relevant with EV's than with ICE vehicles. EV mileage is based on specific driver behavior and car usage. Once you understand this, it's easy to grasp how to both increase and decrease your vehicles range.
First understand the factors that will significantly decrease the amount of range you will get on a given amount of charge :
(a) high speed - the faster you drive, the less range you will get. EPA range is based on a speed of 65 mph, so driving below that speed should increase above the EPA range while the converse will occur driving above that speed
(b) temperature control - the more extreme the temperature (too hot, too cold) the more energy will be expended to regulate passenger and battery temperatures
(c) driving style - the more aggressively you drive (think lots of acceleration), the less range you will get from your EV
Conversely you can get more range by: driving slower, not using or using less temperature control and driving less aggressively. Plug in your details to see what range you should expect today and in the future.
