1. A system for estimating a charging time of a battery of a vehicle, comprising:
an external charger connected to the battery and configured to supply a charging power for charging the battery;
a big data server configured to:
receive a first estimated charging time and an actual charging time of the battery from a charging controller of the vehicle after charging of the battery by the external charger ends;
calculate an error between the first estimated charging time and the actual charging time of the battery; and
calculate an estimated charging time correction value based on the error between the first estimated charging time and the actual charging time of the battery; and
the charging controller further configured to:
charge the battery based on the charging power,
calculate a second estimated charging time based on a state of the battery,
receive the estimated charging time correction value from the big data server, and
apply the received estimated charging time correction value to the second estimated charging time to calculate an updated first estimated charging time.
