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
