Yea, that is odd. Wikipedia says that the second generation Mini Countryman (the only hybrid Mini I could find), has a 7.6 kWh battery. A standard wall outlet at 110V and 15A should charge that in four hours. Of course charging causes heat, which is an important consideration. I’m sure that every car monitors the battery temperature and slows down the charge rate to prevent overheating. But still, 12 hours? Wow. A Tesla plugged into the very same outlet would charge to 50 or 60 miles range in that time.
Even four hours would be a long time to sit at a charger. At that rate you’re best off charging overnight at your hotel, or during the day while parked at work. A charging network that doesn’t tell you the charging capacity of the station before you get there is laughably useless.
I'm really glad I embarrassed myself in this thread by stating it would take 8-12 hours. I have never really tested the charging (always chasing three kids around!). I do believe others are correct and my assumptions were mistaken. I'm happy to now know that I can expect a full charge in only about 4 hours. Thanks hive mind on HN!
