A traditional standard hybrid does not get plugged into an outlet It runs on its own engine plus it has an onboard electric motor that charges the battery in the vehicle..
Now, an EV, (electric vehicle), is different and runs solely on battery power and has to be charged up and plugged in to do so.
I am looking at the first HYBRID vehicle technology which get far superior MPG than standard gasoline only due to the power assist from the direct current battery helping.
Like the original Prius for example....
