1. An update system of a vehicle controller, the system comprising:
an over-the-air (OTA) management server configured to
acquire a state of charge (SOC) change rate when the vehicle controller is updated,
classify vehicles having the SOC change rate below a threshold into a same group,
match a vehicle information and a battery information to the SOC change rate for each group,
select, as a reference group, a group having a largest number of the vehicle information and the battery information matching the vehicle information and the battery information of a target vehicle having the vehicle controller to be updated, and
extract the SOC change rate of the reference group; and

a communication control unit (CCU) configured to
substitute a current SOC value obtained from a battery sensor to the SOC change rate of the reference group,
calculate a remaining SOC value, which is an expected value to be reduced until an update event is completed with a slope on a corresponding SOC change rate, and
update the vehicle controller,

wherein the vehicle information includes a vehicle identification number (VIN) of each the vehicle, a specification of a controller, a distance driven of each vehicle, a duration per trip, and an average number of trips per week from the CCU of each vehicle, and
wherein the battery information includes a maker, type, production date, and capacity of a battery installed in each vehicle.
