Abstract: A battery life prediction device, including a state data generator configured to receive information about a battery in real time and to generate state-of-health data; a state data storage configured to store the state-of-health data and past state data; and a battery life calculator configured to: generate a health state model based on the past state data, generate state prediction data based on the state-of-health data using the health state model, determine whether to modify the health state model based on the state prediction data and the state-of-health data, and calculate a remaining life of the battery, wherein the generating of the health state model includes generating an initial model including a non-linear function, determining an initial model coefficient using a least squares approximation based on the past state data, and generating the health state model based on the initial model coefficient and the initial model

Abstract: A power supply system has a lithium battery. The system includes an uninterruptible power supply (UPS) connected between a commercial power source and a device of a first type. A lithium battery is connected to the uninterruptible power supply. A voltage drop protector (VDP) is connected to the lithium battery and connected between the commercial power source and a device of a second type. Tolerable error thresholds for a voltage and frequency required for the device of the first type are smaller than tolerable error thresholds for voltage and frequency required for the device of the second type.
