Claim 0:
1. A system for estimating a vehicle battery charging time using big data, comprising:
a big-data server configured to:
collect a charge-related parameter of a battery in a vehicle from a plurality of vehicles, to group the plurality of vehicles into a plurality of groups based on the collected charge-related parameter; and
calculate and transmit a first estimated charging time of a group to which the vehicle that is a charging target belongs during vehicle charging; and

a controller installed in each of the plurality of vehicles, and configured to:
calculate a second estimated charging time based on a state of the battery in the vehicle while the corresponding battery in the vehicle is charged; and
calculate a final estimated charging time of the battery by combining the first estimated charging time and the second estimated charging time,

wherein in response to charging of the battery being terminated, the controller is configured to:
reset a weight for combining the first estimated charging time and the second estimated charging time based on an actual charging time consumption.
