PURPOSE: A system and a method for optimizing generation control of a vehicle battery are provided to improve fuel efficiency of a vehicle by varying a target SOC(State Of Charge) of the vehicle battery according to an external temperature. CONSTITUTION: A vehicles wireless internet receiver(11) receives local temperature forecast data from a Korea Meteorological Administration internet server. A GPS(Global Positioning System) receiver(12) receives a GPS signal from a GPS satellite and grasps the position of the vehicle. An ECU(Electronic Control Unit)(13) decides the target SOC of a battery using the position information of the vehicle and local temperature forecast data. A generator(14) charges a battery(15) according to the control of the ECU.
