- Leaving your electric car charging overnight to have it ready in the morning seems like a good idea in theory. But in reality, research suggests doing so does more harm in the long run. Stanford scientists say that it costs more to charge your electric car at night and it could stress out your local electric grid.
- Instead, researchers suggest drivers should switch to charging their vehicle at work or in public charging stations. Another added benefit to charging in the daytime at a public station is that it reduces greenhouse gas emissions.
- “We were able to show that with less home charging and more daytime charging, the Western U.S. would need less generating capacity and storage, and it would not waste as much solar and wind power,” explains Siobhan Powell, a doctor of mechanical engineering and lead study author.
