Abstract
An electronic apparatus includes: an internal power supply to be charged; a charging circuit configured to supply electrical power from an external power supply to the internal power supply; a voltage measurement circuit configured to measure a voltage of the internal power supply; a temperature sensor configured to measure a temperature of the internal power supply; and an estimation circuit configured to estimate a degree of degradation of the internal power supply, wherein the estimation circuit determines whether it is possible to perform a degradation estimation process to estimate the degree of degradation of the internal power supply based on the voltage of the internal power supply and the temperature of the internal power supply, and performs the degradation estimation process on the internal power supply only when determining that it is possible to perform the degradation estimation process on the internal power supply.
