Yes, sorry if I wasn't clear. It's the car that does this, not the charger. But the reason you might want level 2 is that in the scheduled charging situation, level 1 might not have enough time to provide enough energy for your daily commute. (But even if you have e.g. 40 mile daily commute and can only charge 25 miles overnight, you might still be fine to make it to the weekend and make up the difference)
