Scientists at Pacific Northwest National Lab test drove a hybrid Toyota Prius retrofitted to become a plug-in electric vehicle. Using a Smart Charge Controller, which PNNL developed about a year ago, the car battery only recharges when it costs the least and has the least impact on the power grid.
This could prevent future blackouts if millions of drivers plug in their cars after work.
Michael Kintner-Meyer, PNNL Senior Research Scientist said, "We are developing technologies there that are a little bit ahead of its time. And now after three years of technology development and a lot of research, you're seeing the first product. It's very assuring that this technology will come and it will stay."
The whole system would cost you between $30,000 and $40,000 depending on the car.
