锂离子电池进行高效率的充电简介

如何对锂离子电池进行高效率的充电(一)
Driven by integrated functionality and shrinking form-factors, the demand
for portable devices such as cellular phones, PDAs and portable DVD players
has grown significantly during the last few years. The power source has
quickly become a bottleneck for advancing technology, and improvement of
battery-power density cannot keep-up with demand. The lithium-ion (Li-Ion)
battery is widely-adopted because of its high energy density on both a
gravimetric and volumetric basis. To achieve longer system run-time and
smaller size, more and more system designers are finding that improving a
system’s power conversion efficiency with advanced circuit topologies is no
longer sufficient. Battery charging has become another area to focus on for
maximizing battery capacity and extending its service cycle-
