A battery capacity estimating apparatus and a battery capacity estimating method of the battery capacity detecting apparatus are provided. A state of charge and a state of health of a battery are calculated according to dynamic impedance of the battery.

Battery capacity estimating apparatus and battery capacity estimating method thereof

A charging apparatus that can perform a charging action based on an initial capacity of a battery and a charging method of the charging apparatus are provided. The charging apparatus estimates the initial capacity of the battery, calculates an amount of a charging current according to the initial capacity of the battery, and provides the calculated amount of the charging current corresponding to the initial capacity of the battery.

Charging apparatus and charging method thereof

A technology for eliminating acoustic resonance in a fluorescent lamp is disclosed in the present invention. The feature of the invention is to provide a harmonic compensating device to work with the fluorescent lamp and its relative peripheral circuits, such that current-dependent sources are provided to modulate the current in the lamp, thereby spreading the harmonic energy of the current in the lamp and eliminating acoustic resonance.
