I am hoping that someone here can answer the inter-relationship about buying too large of a pack, and then not using its full potential all the time. Example;
If you drive only 60 miles every day round trip, but have a larger pack size, say a 65 KwH, do you end up under utilizing it and lose its capacity at a higher expense than just having a smaller pack (say the 40) and just do more frequent charging. There has to be a cost/ degradation/size analysis graph around, or an explanation for a lay person, (physician) like me to get the science from. My personal concern is, if you buy a (85Kwh) 300 mile range (ideal I know) and only use it for 70 mile days, is there a point of limited returns as to size, and how long that pack will last over time versus what your cost would be on a smaller pack, that may get more charge cycles, degrade faster. I hope I am making sense. Hard to put into words accurately. Thanks in advance.
