A New Study Finds That Charging EVs at Night Could Create a Dangerous Strain on the U.S. Power Grid

We explain how a Stanford University study concluded that charging EVs at night may put strain on the power grid. Thankfully, researchers also highlighted helpful ways for EV owners to lessen their impact.

As
EVs
become more and more popular, researchers are starting to look into the ways that these vehicles will affect our everyday lives. One of the most intriguing revolves around how the U.S. power grid will handle EV charging en masse. Though most experts have said we have nothing to worry about—that the grid can handle it—a new study indicates that’s not quite the case. 
There’s some adjusting the U.S. is going to have to do in order to ensure that our grid can handle EVs on a large scale. But drivers don’t have to make such massive changes to save on their EV

What’s the big deal with charging EVs at night? 

The study was originally published on the peer-reviewed site
Nature
, which
The Washington Post
explains was conducted by researchers at Stanford University. The findings indicate that
charging EVs
at night is an issue because it’s the peak time for electricity usage in the U.S. 
The findings reveal that if most drivers end up switching to EVs over the next decade (as is expected), the current charging trends could increase energy strain on the U.S. power grid by as much as 25%. This is mainly because people charge their EVs at night, which is when energy consumption is highest (and most expensive). 
For many Americans—other than those who work from home—during the morning and afternoon, they’re at work, running errands, or in class. But when they get home in the evening, the lights come on, the TV gets turned on, appliances are running, and for EV owners, their car is on the charger. 
The study notes that if most people only charge their EVs at night, especially once 30-40% of car owners have an EV, the grid might not be able to take the added use without infrastructure changes. 

What does the Stanford study recommend we do about charging EVs?  

Because much of the grid will rely on solar power in the future, it’s recommended that charging EVs happens during the day—when the sun is out. This means that workplaces should have stations available so that
charging EVs is easy
Another easy tip for drivers when it comes to their EV: Set a timer so that the vehicle begins charging exactly at 11 pm. This will save them money, as energy companies charge less during non-peak hours, and it will also help reduce the burden of charging EVs on the U.S. power grid. 
Also included in the study was the fact that the U.S. government is taking measures to reduce the strain caused by charging EVs—and that this implementation process should be complete by the end of the decade.
