Yesterday, I drove my car down to 8%. At 10%, it showed a warning telling me to charge and that turtle mode was active. Still, I could drive at about 110 km/h (~70 mph).
Now I’m wondering how low it can go before it completely stops. Do you still have some range at 0%? What’s your experience?

I’ve hit 0% a few times. You usually get about 10 miles after that.
I’ve done a few miles at 0%, but that was with an Ariya. I’m curious about how much buffer the EV6 gives. Mine started warning about reduced power at around 5%, if I remember right.
I got down to 3% once. You might still have some range at 0%, but the state-of-charge display is just an estimate. It depends on several things, and the battery controller looks at actual voltage to decide when it’s done. So, even at 0%, you might have a few percentage points left.
If you take it that low, make sure to charge back to 100% to let the battery management system balance the cells and reset itself.

Not quite right. The state of charge isn’t a guess, but you can drain the battery differently depending on conditions. Most manufacturers build in limits to protect the battery from hitting actual 0% or 100%.
You’ll usually have 3–5% left when it says 0%. Similarly, you might charge a bit above 100% if the system allowed it.

It depends on the type of battery. NMC batteries, for example, have a flat voltage curve until close to 100%, while Li-ion batteries have a more angled graph. That makes it easier to estimate range for Li-ion batteries.
Also, you should charge NMC batteries to 100% occasionally to recalibrate them. There’s a great video by Engineering Explained on this topic.
I usually don’t go below 52% because I only have a Level 1 charger at home. Dropping below 50% means it would take 24+ hours to get back to 80%, so I try to avoid it until I can get a Level 2 charger installed.
I only have a Level 1 charger, so charging at home is really slow. If my battery drops to 50%, it can take over a day to charge up to 80%. I’d rather wait until I get a Level 2 charger installed at my house, which will be much faster. A 40-amp Level 2 charger can fully charge the car in about 8 hours.
Also, GT mode’s power drops when the battery is under 70%, which makes driving less fun.
