|Abstract: ||In this paper, a Digital Frequency-Locked Battery Charger (DFLBC) for Li-ion battery is proposed. The circuit topology of the proposed DFLBC is same as that of the phase/frequency-locked loop, which means that the proposed DFLBC has lots of inherently abilities as those of phase/frequency-locked loops, such as auto-tracking, autolocking, and high accuracy. Using the above-mentioned abilities, a complete charging process, consisting of three sub-processes: bulk current charge process, variable current charge process and float charge process can be|
inherently implemented. In the proposed DFLBC, the charge trajectory can be digitally programmed according to the behaviors of the Li-ion battery to achieve a better charge performance. Experimental results show that the charge speed of the proposed DFLBC compared with that of a
typical Frequency-locked Battery Charger (FLBC) is improved about 16%.
