Abstract

An embodiment method of operating a battery pre-conditioning system includes checking charging station information including an estimated waiting time for a charging start from arrival at a charging station when an input for a destination corresponds to the charging station and starting a battery warming based on a target temperature reaching time for a battery temperature to reach a target temperature, the estimated waiting time, and a remaining time until the arrival at the charging station.

Claims (32)

1 . A method of operating a battery pre-conditioning system, the method comprising:

checking charging station information comprising an estimated waiting time for a charging start from arrival at a charging station when an input for a destination corresponds to the charging station; and

starting a battery warming based on a target temperature reaching time for a battery temperature to reach a target temperature, the estimated waiting time, and a remaining time until the arrival at the charging station.

2 . The method of claim 1 , wherein starting the battery warming comprises starting the battery warming at a point in time when the target temperature reaching time is greater than or equal to a sum of the estimated waiting time and the remaining time until the arrival.

3 . The method of claim 2 , further comprising terminating the battery warming when the battery temperature reaches the target temperature or when the target temperature reaching time has elapsed.

4 . The method of claim 1 , further comprising, after the arrival at the charging station by a vehicle, terminating the battery warming when a distance between the vehicle and the charging station is longer than or equal to a preset distance.

5 . The method of claim 1 , further comprising determining whether or not conditioning conditions are satisfied, based on the battery temperature, whether a battery pre-conditioning mode is activated or not, whether charging starts or not, or whether the charging station supports fast charging or super-fast charging, wherein starting the battery warming comprises starting the battery warming based on the target temperature reaching time, the estimated waiting time, and the remaining time until the arrival when the conditioning conditions are satisfied.

6 . The method of claim 1 , further comprising:

checking whether the charging station is changed or not, when the estimated waiting time of the charging station corresponding to the input for the destination is longer than or equal to a preset period of time; and

setting the destination based on a result of checking whether the charging station is changed or not.

7 . The method of claim 6 , wherein checking whether the charging station is changed or not comprises recommending an additional charging station that satisfies a certain condition as the destination.

8 . The method of claim 1 , further comprising displaying an operation state of battery pre-conditioning.

9 . A battery pre-conditioning system comprising:

a destination manager configured to check charging station information comprising an estimated waiting time for a charging start from arrival at a charging station when an input for a destination corresponds to the charging station; and

a battery manager configured to start a battery warming based on a target temperature reaching time for a battery temperature to reach a target temperature, the estimated waiting time, and a remaining time until the arrival at the charging station.

10 . The battery pre-conditioning system of claim 9 , wherein the battery manager is configured to start the battery warming at a point in time when the target temperature reaching time is greater than or equal to a sum of the estimated waiting time and the remaining time until the arrival.

11 . The battery pre-conditioning system of claim 10 , wherein the battery manager is configured to terminate the battery warming when the battery temperature reaches the target temperature or when the target temperature reaching time has elapsed.

12 . The battery pre-conditioning system of claim 9 , wherein, after the arrival at the charging station by a vehicle, the battery manager is configured to terminate the battery warming when a distance between the vehicle and the charging station is longer than or equal to a preset distance.

13 . The battery pre-conditioning system of claim 9 , wherein the battery manager is configured to:

determine whether or not conditioning conditions are satisfied, based on the battery temperature, whether a battery pre-conditioning mode is activated or not, whether charging starts or not, or whether the charging station supports fast charging or super-fast charging; and

start the battery warming based on the target temperature reaching time, the estimated waiting time, and the remaining time until the arrival when the conditioning conditions are satisfied.

14 . The battery pre-conditioning system of claim 9 , wherein the destination manager is configured to:

check whether the charging station is changed or not, when the estimated waiting time of the charging station corresponding to the input for the destination is longer than or equal to a preset period of time; and

set the destination based on a result of checking whether the charging station is changed or not.

15 . The battery pre-conditioning system of claim 14 , wherein the destination manager is configured to recommend an additional charging station that satisfies a certain condition as the destination.

16 . The battery pre-conditioning system of claim 9 , further comprising a display configured to display an operation state of battery pre-conditioning.

17 . The battery pre-conditioning system of claim 16 , wherein the display comprises a cluster of a vehicle, an audio/video/navigation/telematics (AVNT), or a combination thereof.

18 . The battery pre-conditioning system of claim 17 , wherein the destination manager comprises the AVNT of the vehicle.

19 . The battery pre-conditioning system of claim 9 , wherein the battery manager comprises a battery management system of a vehicle, a vehicle control unit, a hybrid control unit, or a combination thereof.

20 . A battery pre-conditioning system comprising:

a destination manager configured to check charging station information comprising a distance between a vehicle and a charging station after arrival at the charging station when an input for a destination corresponds to the charging station; and

a battery manager configured to terminate battery warming at a point in time when the distance between the vehicle and the charging station is longer than or equal to a preset distance after the arrival at the charging station.
