Claim 5:
6. A method of estimating a vehicle battery charging time using big data, the method comprising:
collecting, by a big-data server, a charge-related parameter of a battery in a vehicle from a plurality of vehicles;
grouping, by the big-data server, the plurality of vehicles into a plurality of groups based on the collected charge-related parameter;
transmitting, by a controller in a vehicle, charge-related data at a time at which charging begins to the big-data server while the battery in the vehicle is charged;
calculating and transmitting, by the big-data server, a first estimated charging time of a group to which the vehicle belongs based on the charge-related data at the time at which charging begins;
calculating a second estimated charging time based on a state of the battery; and
calculating a final estimated charging time of the battery by combining the first estimated charging time received from the big-data server and the second estimated charging time,
wherein calculating the second estimated charging time comprises:
in response to charging of the battery being terminated, resetting, by the controller, a weight for combining the first estimated charging time and the second estimated charging time based on an actual charging time consumption.
