Normal plug charging 120v @1.2kw

[philbur]

On road trips I have been charging with an extension cord and normal plug. Charges at 1.2kw and usually get 12-15% overnight. It’s slow but always impressed with how much it gets! Do others do that? My thinking is that people don’t know how good it is! Will def cover my daily drive from our cabin to parking at Whistler this trip. Every electron counts!

I think you and I may have different definitions of “good”.

With the slow charging + 20min 50kw charging while I was sorting my skis and another charging opportunity I’ll be topped up for my drive back home! It’s better than having my family wait for charging in the car which is the only thing they don’t like with our EV road-trips.

1-3 miles of range per hour on a 110 plug is normal. That’s too slow for me personally, as one long-distance trek requires a 24 hour charge cycle. I guess it’s fine for your vacation, but 30 miles per hour of charge from a 40 amp circuit is the way to go. As always YMMV.

Couple of Porsche TSBs about AC charging say:

• 110V Charging is for emergency use only. The relatively high current (8A to 10A) loads household circuits and receptacles for an extremely long time.​

Another 2022 Porsche TSB mentions adjusting minimum current setting for PMC+ and PMCC when charging at 110v:

Interesting and thanks for sharing! The constant load for long periods is def new for existing circuits. I only do this on trips but will keep an eye on it

Not discounting earlier points which are valid. I’ll share my experience.

I used 110v to charge for about three months when I moved into a new house (prior to charger install). My electric usage spiked to 4 times higher than normal. I basically left he car plugged overnight, every night. So the 10-15% gain per day met my weekly usage.

I attribute this to the overhead energy use when charging slowly. I estimated that approximately 1000 watts of power is used in overhead at any given time. That adds up to very inefficient charging.
