But is that an issue? As long as you always have enough juice to get to a fast charger, and you can always get back to 80% by Friday morning, isn't that enough?
Sure, it's nice to have a 9kW charger, and I'm glad I do. But if I would have been forced to pay $5K to upgrade my mains connection I would likely have just kept the $5K and charged on 120V.
My Bolt lets me say that the circuit is dedicated to it at home and pulls 12 amps instead of the 8 amps it would pull anywhere else. It's trying to make sure it doesn't overload the circuit.
We are moving to a newer home and I already have the 240V charger installed there. Looking forward to 25-30 miles of range per hour (running at 32A normally but have a dedicated 60A circuit) instead of the 3 I'm getting now.
At this house, the 200A panel is full so I would have had to add another panel.
My 200 service was also "full" but when monitoring the energy, we rarely pull above 40 amps. We'd only hit 200 if the emergency heat was running at max for both HVACs, the oven was on, the water heater was going and the dryer was running. Pretty hard to do by accident, nigh impossible if you think about it
