METHOD OF PREDICTING TIME FOR CHARGING BATTERY OF ECO-FRIENDLY VEHICLE

A method of predicting time for charging a battery of an eco-friendly vehicle can include: measuring a temperature and a voltage of the battery using one or more sensors; comparing the measured temperature and voltage with pre-stored data values; identifying a charging step among a plurality of charging steps; calculating a charging current value and a cutoff voltage value according to the identified charging step; and calculating an expected charging time by adding a second time to the expected charging time when a first time is greater than the second time or by adding the first time to the expected charging time when the second time is greater than the first time.
