Multistage Constant-Current Charging Method
for Li-ion Batteries
Abdul Basit Khan, Van-Long Pham, Thanh-Tung Nguyen and Woojin Choi,
p
a
p
er
p
ro
p
oses a uni
q
ue method to nd the
o
p
timal charge
p
attern (OCP) of multistage constant-current
charging (MSCCC) method by using RC based e
q
uivalent circuit
model for Li-Ion batteries. Both and stages based MSCCC
methods are discussed. The method of nding the e
q
uivalent
circuit model and o
p
timal charge
p
attern by e
q
uations are also
ex
p
lained. Ex
p
erimental results with a Ah Li-ion battery are
used to validate the
p
ro
p
osed method. The
p
ro
p
osed method is
uni
q
ue in that it can charge the battery u
p
to ca
p
acity in a
shorter time. Com
p
ared with conventional CC-CV method, the
charging time (CT) and the charging eciency by the
p
ro
p
osed
method are im
p
roved by a
pp
roximately and
res
p
ectively.
