14 hours 0% to 100%. With a battery that large, it makes sense to charge at 11.5 kW to reduce the charging time from 14 hours to 9 hours.
Obv you situation may vary, but after nearly 5 years of driving only EVs with our two Model 3s, the ability to charge at the 48 amp vs 40 amp vs 32 amp has never once made any difference whatsoever. FWIW, here is why, and I think my experience is fairly typical:
• I have rarely arrived home with less than, say, 20% battery (maybe a two dozen times across two vehicles or say an average of a couple time a year per vehicle). But even when I have...
• I normally charge to 80%, so even a large battery will recharge from say 20% - 80% easily overnight.
• I have almost never arrived at home with say, 10% or 15% need to turn around and drive another 100+ miles an hour later (this has happened maybe twice that I can recall)
• In those instances where I have rare charging demand that exceed a 7.7 kw capability, I have plenty of DCFCs around to stop in for 10 minutes and add an extra 100 miles or so if I need it.
• So my personal rule of thumb on this is a 70% charge in 10 hours is most I need to buy, 60% charge in 10 hours is fine. On a 100 kwh (useable) battery, a 7.7 kw charger (32 Amp) is more than enough. If I have a 125kwh+ Rivian or similar, I would bump to 40 Amp 9.6 kw.
As I say, others may have different needs, but after 11 years of plugin vehicles and almost 5 years of EV only driving, I have discovered that I paid for more charging than I needed (two NEMA 50 plugs) and that I would certainly never pay for more. My personal lessons learned:
• I will never buy another wall charger (I own two, one is broken) - they are expensive, have lots of redundant features and they can only be used in one place for one purpose
• I will especially never buy another hard-wired charger (I own one) - they are expensive to repair and even less flexible than a wall charger with a NEMA plug
• I will never use an EVSE wifi app/connection - they do nothing for me and so-called "smart" EVSEs break more often and offer nothing I cannot get already from the vehicle I will not pay for this feature and I prefer units without a wifi connection at all
• I will only buy EVSEs that are portable and can be used on a minimum of a NEMA 14-50 and standard 115V wall plug
• For reasons above, I will not pay extra for a 40 Amp charger unless I get a vehicle with >110kwh battery
I hope someone finds this perspective useful.
