Why shouldn't I charge my 64 kWh Kona EV to 100% every day?

OK, one reason for charging to 80% only is a battery condition issue. But we should remember the second one -- when one starts the trip with 100%, the car can't recuperate any kW during first kilometers, regardless the trip profile. So, that 20% capacity left plays as a kind of buffer for recuperation.

 

You would have an amazing view if you lived on a hill that returned 20% recuperation on the way down. Can't say I've ever recovered more than 1% on a single downhill.

 

I was going to say, on a coast down Everest to the Indian Ocean this strategy might make sense.

 

The car recuperates just fine with 99% SOC. At least mine does.

 

Mine too but I won't test that anymore. Leaf did not. Maybe someone has already tested where the limit is in a long downhill...

 

My house is a an elevation of 4061 ft. From my house is about ten miles before I start to descend 3000 ft in 20 miles. I always charge my car to 100% when I am going down to the valley. I have never had a problem with regeneration. I arrive at the bottom of the hill with 1 or 2 mile more then I started a the top of the hill.

 

Same here, based on our experience with leaving home (heated garage) at 100% SOC and driving into a -12C environment.
