One year might be a little short time to establish differences.How am I doing on degradation? Well, after over a year...
I still have full range(507km) after 40.000km/25.000mi and 16 months.
Teslafi is not very exact down to the mile because they have limited data(rounded SOC) to do the range calculation. Still full range on every full charge
Most people think that “the miles” that is the main factor for degradation. Its not.
Specially the first years(5 or so) the calendar aging is the bigger part of the cars loss of range (see the calendar aging graph in my last post above).
Depending on the climate, people mostly have 3-4 to 8% the first year and then gradually reducing rate after that.
The cyclic aging for most people is around the 1% mark. Most people probably is below, buth people driving much each year with bigger cycles might use up 1-2% or so.
Remember, NCA cells typically loose 20% capacity for 500-750 or so cycles with 100-0%, and perhaps hold up at least 2000-3000 full equivalent cycles with normal use. 2000 cycles is some 1.000.000km for a LR or P so driving 20.000km/ 12500mi each year will eat 20.000/1.000.000 = 2%
Smaller cycles will degrade the battery less, fir the same amount of miles.
