Hybrid cars have batteries, electric motors, and sophisticated power electronics, so it's easy to assume they need to be plugged into an outlet like an electric vehicle. But most traditional hybrids don't work that way.
Instead, they can recharge their batteries while you're driving. The gasoline engine provides some of the energy, while the car can also recover energy that would otherwise be wasted during braking. That's the basic idea behind a hybrid: use electricity when it makes sense, recharge the battery while driving, and let the gasoline engine handle the rest.
