Readying the nation’s electric system to deal with the load that electric vehicles will produce requires figuring out, among other things, the rate at which EV adoption is going to occur and where EVs are going to be charged.

A study by MIT researchers provides some clues about the latter.

The study, which was published in the journal Nature Energy, tried to identify the infrastructure improvements that would give EV adoption the biggest boost.

One finding, which surprised me, was that installing charging stations on residential streets, rather than just in central locations such as shopping malls, could have an outsized benefit in promoting EV usage.

That also could have an outsized effect on the load residential circuits need to be equipped to handle to make widespread EV adoption possible.

This is pretty surprising to me, too-- when I drive my car I know that I'm able to get my day's trip done without needing to charge before coming home, or if I'm going for a longer trip then I plan around the public stations that I need to help me. I can't imagine the use case that makes it necessary for me to 'top off' while parked on a residential street. But maybe there's something about the mindset between the early adopters and the rest of the market that this study is looking into capturing?

Peter, Thanks for the article. I have been driving electric for 30 years.  We used to convert our own cars and pickups. 

   The biggest change I see are the batteries are now amazing. Long life and non toxic with capacity getting better year year .  I am surprised at the major reasons many switch to electric. We see 50% get them so they can use the HOV lanes. Many others because they are fast. Very few choose them for the environment or because electric is 4x less cost than gas. 

   Charging seems to be everywhere EVen many apartments are adding free charging. Whole foods and other stores and malls also add it. 

    On long trips Tesla has held the lead for 8 years but Electrifying America is growing fast but more expensive. It has changed a lot in the past 10 years and the future looks EVen better. Thanks.

I see what you did there!

Jim,

Glad you liked the link. I'm impressed with your background. You've been on the cutting edge of this stuff for a long time.

You're right that the batteries are amazing and they're going to get better. Storage technology just keeps advancing, which is good because grid decarbonization would be impossible otherwise.

Peter
