Document Type and Number:
WIPO Patent Application WO/2024/039066
Kind Code:
A1
Abstract:
A charging time estimation device, according to one embodiment disclosed in the present document, comprises a communication circuit and a processor, wherein the processor may be configured to: receive, from an electronic external device through the communication circuit, first battery information including a current value, a temperature value, a state of charge (SoC), and a state of health (SoH) during a specified time period of a battery included in the external electronic device; receive, through the communication circuit, information about a driving speed of the external electronic device during the specified time period and/or information about whether the external electronic device and an external charger are connected to each other; extract a charging section within the specified time period on the basis of the first battery information, the information about the driving speed, and/or the information about the connection state during the specified time period; and generate a charging time estimation model by using the current value, the temperature value, the SoC, and the SoH at a first time point of the charging section and the SoC at a second time point of the charging section.
