Electric Car Battery Basics: Capacity, Charging and Range

With a conventional car, it's easy to understand gas tank capacity and fueling. But these concepts don't translate to EVs and their batteries. Range, charging and capacity can vary.

it is nice that there is some actual information coming out on these cars

Curious as to how long battery will hold the charge. Say, for example, you park your EV at the train station parking lot for the day-not charging. Will charge drop off significantly over 8-9 hours of car sitting in the lot?

If it's a true EV with lithium ion batteries (as opposed to a hybrid that might be using nickel metal hydride batteries), you would lose very little charge over the course of a month of storage---maybe 2%. As the outside temperature decreases, this discharge rate would increase, but on a 8 hour storage basis I doubt you'd lose any significant charge at all.

Ambient temp has a huge affect on capacity batteries hate heat and extreme cold weather. Also as an average there is a 20 percent of loss whilst charging and use the car manufacturer advertise a battery capacity but not it's useable capasity this needs to be addressed
