要約(英語): Accompanying with the rapid popularization of portable embedded systems, the battery technology continues remarkable development to achieve long battery lifetime. To apply lithium-ion batteries to portable embedded systems, it is necessary to take into consideration cell voltage response to the change of load. In this research, we have developed an accurate battery simulator, which simulates the electric behavior of a battery. It simulates the temporal response of state-of-charge (SOC) depending on its load. It also introduces more accurate characteristic of the internal resistance which was not taken into consideration in conventional models. Furthermore, operation of recovery and consumption of battery capacity has been introduced for the simulator. Moreover, the technique of carrying out the calibration and characterization of the parameter peculiar to a battery is proposed. The experimental results show the validity of a battery model and characteristic extraction technique.
