determining a current drawn from the battery;

determining an initial SoC of the battery; and

predicting the remaining time based on the current, the initial SoC, and the capacity of the battery.

5 . The method of claim 4 ,

wherein the current drawn from the battery comprises a self-discharge current of the battery; and

wherein the method further comprises:

predicting the self-discharge current based on the initial SoC, the ambient temperature, and the self-discharge characteristics of the battery.

6 . The method of claim 4 ,

wherein the current drawn from the battery comprises a current required by a load of the battery; and

wherein the method further comprises:

predicting the current required by the load based on the initial SoC, the ambient temperature, the internal resistance of the battery, and power required by the load.

7 . The method of claim 1 , wherein determining the remaining time further comprises:

determining that a condition has occurred; and

in response to the determination, updating the remaining time.

8 . The method of claim 7 , wherein the condition comprises at least one of:

receiving a user command for updating the remaining time;

determining that a user-specified requirement is satisfied; or

determining that a status of a device using the battery has changed.

9 . The method of claim 7 ,

wherein the time to be updated is a first remaining time determined at a first point in time; and

wherein updating the remaining time comprises:

determining, at a second point in time, a second remaining time; and

computing an updated remaining time based on a weighted function of the first and second remaining time.

10 . The method of claim 1 , wherein the battery is used in a vehicle.

11 . The method of claim 10 , wherein the power demand for the battery comprises power required by a vehicle monitoring system of the vehicle.

12 . The method of claim 10 , wherein the notification indicates whether the battery has enough energy for the vehicle to reach a charging station.

13 . The method of claim 12 , wherein:

when determining that the remaining time reaches a preset time duration or corresponds to a minimum energy level of the battery required by the vehicle to reach the charging station, presenting the notification via a user interface.

14 . The method of claim 12 , further comprising:

acquiring location information of one or more charging stations;

determining an average distance from the vehicle to the charging stations; and

determining the minimum energy level based on the average distance.

15 . A notification system of for a battery, the system comprising:

a memory storing instructions; and

a processor configured to execute the instructions to:

predict an ambient temperature of the battery;

determine a power demand for the battery;

determine a state of health (SoH) of the battery;

predict a remaining time for a state of charge (SoC) of the battery to reach a predetermined level, based on the ambient temperature, the power demand, and the SoH; and

provide the notification regarding the remaining time.

16 . The system of claim 15 , wherein the processor is further configured to execute the instructions to:

acquire historical weather data of an area where the battery is located;

estimate future weather condition based on the historical weather data; and

predict the ambient temperature based on the future weather condition.

17 . The system of claim 15 , wherein the processor is further configured to execute the instructions to:

determine a current drawn from the battery;

determine an initial SoC of the battery; and

predict the remaining time based on the current, the initial SoC, and a capacity of the battery.

18 . The system of claim 17 ,

wherein the current drawn from the battery comprises a self-discharge current of the battery; and

wherein the processor is further configured to execute the instructions to:

predict the self-discharge current based on the initial SoC, the ambient temperature, and self-discharge characteristics of the battery.

19 . The system of claim 17 ,

wherein the current drawn from the battery comprises a current required by a load of the battery; and

wherein the processor is further configured to execute the instructions to:

predict the current required by the load based on the initial SoC, the ambient temperature, an internal resistance of the battery, and power required by the load.

20 . A vehicle, comprising:

a battery;

a battery management system configured to determine a state of charge (SoC) and a state of health (SoH) of the battery; and

a controller configured to:

predict an ambient temperature of the battery
