More Information
Summary:An electronic apparatus (100) includes: a battery (130); a first calculator (110) configured to obtain sensing data of the battery (130) using a sensor (140), determine first state information of the battery (130) using the obtained sensing data and a first battery model (161), and preprocess the obtained sensing data; and a second calculator (120) configured to receive the preprocessed sensing data from the first calculator (110), determine an aging state of the battery (130) using a second battery model (171) and the received sensing data, update a parameter of the first battery model (161) based on the determined aging state, and transmit the updated parameter to the first calculator (110).
