@daveo4EV I recently charged at my parents house using their Wallbox charger and my dad told me after the fact that according to the Wallbox app, I only pulled 6kW when charging. His Bolt charges at 12kW. Come to think of it, I've actually never seen higher than 6kW except when DC fast charging. I only get 5.1kW on my charger at home (but that's not surprising, I believe it's on a 30A circuit) and I also get somewhere between 5-6kW when using the Chargepoint chargers at work.
Any idea why I'm not getting the full, expected 11kW from my parents Wallbox charger when their Bolt is getting the full amperage?
@submatrix If your parent's Wallbox is indeed on a 30A circuit, the max your or any other vehicle will draw is 6.6kW.I'm unaware of any way to "limit" AC charging AMPs with the Taycan (doesn't mean it doesn't exist, just means I don't know how to do it)…
there should be no reason your Taycan did not charge at 11/12 kW if the EVSE provides that level of power.
the best source of information as to charge rate is the internal center display while charging - if you tap the mi/minute value in the main charging display you can see kW instead of furlongs-per-fortnight units…
might be a software limit on the Wallbox for cars it does not recognize?
99% of L2 chargepoint stations are 30 amps @ 208V - which math says is 6 kW - so only getting 6 kW from a chargepoint charger is normal and expected. This is the main reason the 19.2 kW optional charger is pointless in North America - there is very very very limited L2 AC charging infrastructure that is greater than 30/40 amps - if you option the 19.2 kW onboard charger it's going to be very very very rarely used "in the wild"…
do you get 9.6 kW @ home?
I'm going to bet on the Wallbox rather than the Taycan here - and maybe some configuration on the Wallbox was in play during your charging session.
Perhaps your parents are mentioning the Bolt's L2 charging maximum power, as opposed to stating actual observed?
In order for them to observe max L2 charging speeds for the Bolt (11.5kW for the latest model?), they would need their Wallbox running at 48A on a 60A circuit.
