A level 2 charger is many times faster and a requirement at home for owning a Taycan. This is a good chart to give you an idea of charging time depending on the level 2 charger you install. But anything 40 amps or more should get you a full charge overnight (8 hours) while my 16 amp charger nets about 50% in that amount of time.
And in the US, I believe that 9.6 kW is all the Taycan will do. At least for the 2020 MY.
For L1 charging using the 120v charge cord, please note that the Porsche Mobile Charger Connect limits the charging amps to 8A (you can go down to 6A if desired).here is charging time table for a Taycan by “breaker amps” - I’ve include two example charge times
NOTES:
left most column is “breaker amps” - this is the size of the breaker in your circuit panel
next column is “charging amps” - this is the number of amps available for charging for that size breaker - north american building codes require 80% load on devices with continuous load (EV chargers - EVSE’s) are continuous load devices, so they are only allowed to use 80% of breaker/wire’s rated capacity for safety reasons.
L1 charging time is hours @ 120 volts and XX AMPs
L2 charging time is hours @240 volts and XX AMPs
and I’ve included a sample of two different battery % charge
100% - this is if you were charging the taycan from 0% charge (very rare circumstance)
40% - this is if you were charging the taycan from 40% charge to 80% charge (heavy daily use)
40% charge use is at least 95 miles of driving with the Taycan - 95 miles is well beyond typical daily use for 99% of drivers…so 40% daily charge is pretty extreme - you’re daily use and charge % will likely be much less
worse case is L1@15 amps taking 59 hours to charge the battery to full
best case is L2@50 amps taking 3.54 hours to charge the battery from 40% to 80%
charge times are ideal in this table - I’d expect the actualy time to take 10-15% longer
I’ve modeled the Taycan as an 85 kWh battery for this table - 83.4 is porsches “published” usable capacity so the most kWh you should ever see put into a Taycan battery is 85 kWh or slightly less.
That sort of thing is pretty common from the car makers. They're scared of people having older wiring or outlets that can't handle the heat from having 12A continuous.
