Hyundai Motor Group will offer free charging for drivers who rent its electric vehicles from Lotte Rent-a-Car in Jeju starting Monday, the automaker said Sunday. Drivers will be able to charge their rented EVs to up to 80 percent for free if they use a fast charger installed at Hyundai Motor charging stations named E-pit. There are three E-pit stations on Jeju Island with 16 chargers. The free charging service will be offered through Oct. 15. (Hyundai Motor Group)
