Abstract:
This study considers the state-of-charge estimation
for lithium-ion battery in low-cost portable applications where
the current measurement is presumed unknown. By regrading
the current as an unknown input, this problem is reformulated
as optimal filtering of nonlinear systems with an unknown input.
A novel unscented recursive three-step filter is then proposed
to simultaneously realize the SOC and current estimation. The
unscented transformation is utilized to obtain the mean and covariance
of the system state. Evaluation of the proposed approach
is made by experiments under two different operating conditions.
Experimental results show that the SOC estimation errors are
within 5% bound, indicating that the proposed algorithm is
feasible.
