Not sure what this means. Maybe I will ask my son who is doing research on making batteries last longer and charge faster. However, I just want a car that drives. After being exhausted totally from being at the dealers all night buying this monstrosity, who had the energy to have the salesman explain how to drive the darn thing. Now the value is half the purchase price 2 years later. If I could get rid of this junk, I would do it in a minute.
