so where do you disable that? That is really a stupid feature. Its like kid was given infinite RAM memory to program and he put all kinds of useless options in.
It's accessed through the instrument cluster display (forgetting the technical name right now), under the icon that looks like a gear. It's not on by default, so if you didn't enable it, it isn't doing anything.
And actually, it's not a stupid feature at all
if it works. The Leaf and the Volt both have extensive time-of-use-rate programming, where you can tell it when electricity is cheap, moderately expensive, or very expensive on your electric plan, tell it what your schedule is, and whether to prioritize being ready to go when you normally leave or just charge as cheaply as possible. It even has separate weekday/weekend scheduling. This is a big money-saver, and obviates needing any fancy charger to handle that. I can just say "Power is really cheap on my EV plan from 11pm to 7am, take advantage of that", then plug the car in whenever. It'll start charging at either 11pm or when I plug it in, and stop at 7am. A couple of button pushes overrides that temporarily to charge immediately or using part-peak, and I can do that while driving if I want. Saves quite a bit of money and is easy once you set it up.
I was expecting at least a simplified version on the Clarity ("charge between 11pm and 7am"), but while it does have the basic timer, as noted it's stupid and won't charge if you plug in after the start time, takes about half a dozen button pushes to change between timed and charge immediately, and you can't adjust it while the car is in drive. It's nearly worthless, and seems like a
huge oversight for a plug-in vehicle.
