Method And System For Collocated Gasoline Pumps And Charging Stations For Ultra-High Speed Charging
Systems and methods for collocated gasoline pumps and electric vehicle charging stations for ultra-high speed charging may include a fuel station having fuel pumps, electric vehicle supply equipment, and a charge buffer. The charge buffer may receive electric current from an electricity supply grid and supply current to the electric vehicle supply equipment. The electric vehicle supply equipment may be configured to control throttling down of maximum charging power based on a type of cell. The controlling may include delaying the throttling for a first type of cell relative to a second type of cell. The electric vehicle supply equipment may be configured to apply a voltage to batteries above their battery voltage limit when charging. The electric vehicle supply equipment may charge batteries at a rate greater than 4 C, 5.6 C, or 10 C. The electric vehicle supply equipment may supply greater than 120 kW.
