In addition, the control unit 240 can control each configuration of the vehicle 1 differently when the vehicle 1 is in the start-up ON state and when it is in the start-OFF state.

The control unit 240 can determine whether to generate a discharge risk signal of the battery 250 when the starting of the vehicle 1 is turned off.

4 (a) shows a condition for judging a discharge risk of the battery 250 according to an external temperature. Referring to FIG. 4A, the controller 240 generates a discharge danger signal for an alarm when the SOC is 70% or less when the external temperature at the time when the vehicle 1 is turned off is -30 ° C .

As another example, the control unit 240 can determine whether the charged state of the battery 250 satisfies the transmitted determination condition based on the travel distance of the vehicle 1 when the vehicle 1 is turned off.

The control unit 240 can determine the driving distance of the vehicle 1 depending on whether the battery 250 has a replacement history and determine whether the battery 250 Can be judged whether or not the charged state of the battery pack satisfies the transmitted judgment condition. At this time, the replacement history of the battery 250 may be sensed by the battery sensor 210 or may be received from the server 300.

If the battery 250 has a replacement history, the control unit 240 may store the distance traveled at the replacement point separately. The controller 240 may calculate a distance obtained by subtracting the stored travel distance of the replacement point from the current travel distance, It can be decided by mileage.

4B shows a condition for judging a discharge risk of the battery 250 according to the running distance of the vehicle 1. In FIG. Referring to FIG. 4 (b), the control unit 240 can generate a discharge risk signal for an alarm when the SOC is less than 40% when the vehicle 1 travels at 20,000 km, It is possible to generate a discharge danger signal for an alarm when the SOC is less than 60%.

The control unit 240 determines whether the charging condition of the battery 250 is satisfied based on the external temperature at the time when the starting of the vehicle 1 is turned off and the traveling distance of the vehicle 1 .

5 (a) shows a judgment condition for a discharge risk according to the travel distance when the external temperature is 0 캜, and Fig. 5 (b) shows a discharge condition according to the traveling distance when the external temperature is -15 캜 FIG. 5 (c) shows a judgment condition for the discharge risk according to the travel distance when the external temperature is -30 ° C.

5, when the external temperature at the time when the vehicle 1 is turned off is -15 ° C, the control unit 240 can use the determination condition data of (b) Is 40,000 km, it is possible to generate a discharge danger signal for an alarm when the SOC is 50%.

The above-described operation is the operation of the control unit 240 when the vehicle 1 is turned off. Alternatively, when the vehicle 1 is turned on, the control unit 240 may control the communication unit 220 to receive the determination condition of the discharge risk of the battery 250 from the server 300, The judgment condition stored in the storage unit 230 can be updated.

Specifically, when the vehicle 1 is turned on, the control unit 240 receives a determination condition from the server 300 and determines whether the version of the determination condition stored in the storage unit 230 is the same as the version of the received determination condition Can be determined.

If the version of the judgment condition stored in the storage unit 230 is the same as the version of the judgment condition received, it means that the version of the judgment condition stored in the storage unit 230 is the latest version. In this case, Do not update.

On the other hand, the fact that the version of the judgment condition stored in the storage unit 230 is not the same as the version of the judgment condition received means that the version of the judgment condition stored in the storage unit 230 is not the latest version, 240 may perform an update of the determination condition.

The control unit 240 can update the existing stored judgment condition by receiving the new judgment condition from the server 300 and storing it in the storage unit 230. [

When the server 300 receives the discharge risk signal and the version information of the determination condition from the control unit 240 of the vehicle 1, the server 300 can determine whether the version of the received determination condition is the latest version. The server 300 may determine whether to transmit an alarm signal to the user terminal 400 according to the determination result.

Specifically, when the version of the determination condition received from the communication unit 220 of the vehicle 1 is the latest version, the server 300 can transmit an alarm signal to the user terminal 400. [ The server 300 may not transmit an alarm signal to the user terminal 400 if the version of the determination condition received from the communication unit 220 of the vehicle 1 is not the latest version.

When the user terminal 400 receives the alarm signal from the server 300, the user terminal 400 can provide an alarm notifying the danger of the battery 250 to be discharged. In this case, the user terminal 400 may provide information such as the state of charge of the battery 250 received from the server 300 together.

Accordingly, the user can be provided with an alarm only in the case of a discharge risk of the battery 250 determined based on the determination condition of the latest version, thereby preventing false alarms.

Referring to FIG. 8, the vehicle 1 may determine whether the start of the vehicle 1 is off (810). If the start of the vehicle 1 is off, the vehicle 1 may detect a discharge danger signal (A). ≪ / RTI >

Specifically, the vehicle 1 can confirm the current driving distance (820) and check whether there is a battery replacement history (830).

If there is a detection of the battery replacement history, the vehicle 1 may determine the distance (840) as the mileage distance excluding the mileage of the pre-stored replacement point in the current mileage.

Alternatively, when there is no detection of the battery replacement history, that is, when there is no battery replacement history, the vehicle 1 can determine the current mileage as the mileage.

After the travel distance is determined, the vehicle 1 can check the detected external temperature at the start-off time (850). At this time, although the vehicle 1 can determine the outside temperature at the start-off time after determining the driving distance as shown in FIG. 8, the determination of the traveling distance and the confirmation of the outside temperature can be performed at the same time, May be performed before the determination of the mileage.

The vehicle 1 can check the determination condition based on the external temperature, the travel distance, and the state of the battery 250 (860) and determine whether the charged state of the battery 250 satisfies the determination condition (870) .

When the charged state of the battery 250 satisfies the determination condition, the vehicle 1 may generate a discharge danger signal (880).

The operation of the vehicle 1 after the generation of the discharge risk signal is the same as in Fig.

Thus, it is possible to provide an alarm considering the battery condition more specifically, and the reliability of the alarm system can be increased.
