Abstract:
1. A method of controlling charging of a battery for supplying power to a vehicle according to a driving state, the method comprising: detecting, by a sensor, a speed of the vehicle; generating, by a generator, power according to a driving state of the vehicle; controlling, by a controller, a charge to the battery using generated power of the power generator based on a signal of the vehicle speed detector calculating, by the controller, an average vehicle speed for a set time; updating, by the controller, the average vehicle speed at an update period shorter than the set time; changing, by the controller, a state of charge charging band, wherein the state of charge charging band is a charging reference of the battery based on the average vehicle speed; and charging, by the controller, the battery according to the driving state based on the state of charge charging band, wherein the updating of the average vehicle speed comprises: calculating, by the controller, an updated average vehicle speed by deducting a vehicle speed corresponding to an initial stage of the update period in the set time from the average vehicle speed and adding a vehicle speed corresponding to an end stage of the update period in the set time to the average vehicle speed.
