There are two types of hybrid vehicles in the Sonata model (the 7th generation): the HEV and PHEV. You can charge the PHEV and it has the charging port for the high-voltage system. But you can’t charge the HEV and there is no port.
Now, a lot of people ask if they must or should charge the Sonata PHEV. The answer is not that clear: you don’t have to charge it, but if you do, you will get far battery gas mileage on your car. That’s why it’s recommended to plug in a charger from time to time to give some juice to the high-voltage system.
