All things digital using technology to improve lives of people

Elon Musk explains why charging your EV to 100% on a road trip is a mistake:

On a road trip, your instinct is to fill the battery all the way up.

That's how you'd treat a gas tank.

But a battery doesn't work like a gas tank.

Charge to about 80%. Drive it down to 10% or less. Repeat.

This is just for long trips, when you want to spend as little time at the charger as possible.

Elon: "Getting from 80 to 100, it takes about as much time as getting from 0 to 80."

The reason is what's happening inside the battery.

Lithium ions travel from one side to the other, looking for a place to settle.

Think of them as cars hunting for a parking spot.

When the lot is empty, they zip right in.

As it fills up, they have to circle around, like at a packed mall.

So the closer the battery gets to full, the slower it charges.

The last few spots take the longest to find.

It’s been remarkable to watch the world mobilize and rally behind science as humanity tackles COVID-19. We’re supporting ongoing clinical trials for hydroxychloroquine and are prepared to donate 130 million doses globally. #COVID19 #Covid_19

I appreciate the demonstration and testing, but part of me secretly wants this robot to get a little payback.
