I'm not aware of any serious studies that support that assertion. In fact, general consensus is that, by increasing time-of-generation to time-of-use flexibility, EVs will drive down electricity prices.

Case in point: during summer in Europe, assuming sunny weather, the 15-minute daytime spot price for electricity is generally negative due to the glut of PV supply. In other words: you can charge your car during the day and get paid for doing so. Then, at night, you feed back, like, 50% of your stored energy to the grid.

You get to drive to work in the morning just fine (where you can charge your battery again, for free-or-less), and the (very little) you got paid for half-discharging your car during the night definitely did contribute to lowering prices during that time as well...

The only problem is that these assumptions rely on non-existent infrastructure which costs a ton of money to build and maintain. The overwhelming majority of parking spots don't offer EV charging, so people would have to charge their car at night when energy is expensive.

Even if we did have EV charging available everywhere, excess of energy during times of peak production is the reason why energy might be cheap or free. As soon as you actually start utilizing that excess, the prices will stabilize around the average market rate.
