The current state of the art is somewhere in between with 18 minutes per ~3 hours. It even helps to split charging into shorter sessions (2x 9 minutes), because batteries charge fastest when they're about 25% full.
Keep in mind that EVs charge unattended, so you only spend a minute plugging in, and can leave to get a coffee, etc.
- silisili 3y agoHow 'guaranteed' is that rate? I don't keep up with it like I probably should, but seem to often read that some chargers are outdated, and sometimes you have to 'share' if somebody else is charging nearby?
- pornel 3y agoIn the EU, there are Ionity and Fastned networks that can guarantee their chargers will be fast enough for this (>=250kW), and together they have a pretty decent coverage along major highways. There are setups that have their max rated power per dispenser (“pump”), and halve it if two cars are plugged in to the same dispenser at the same time. Good chargers can do 300kW. If that splits to 150kW it’s not too bad - maybe 5 min slower, rather than double. That’s because the max speed the car can take is a curve, and that only flattens the peak. However, for the 18-min charging the biggest gotcha is the temperature. In Hyundai/Kia it requires the battery to be at 20-25°C. That’s easy in the summer. In the winter the charging speed can drop as low as 80kW.
