| Summary: | electrochemical battery model of a lead acid battery cell as
a state-of-health indicator in an embedded application. The
model equations are a set of coupled highly non-linear partial
differential equations that evolve with time. At each time
step, these equations are solved using Newton’s Method,
and a direct skyline LU solver without partial pivoting is
used to solve for the battery cell’s state at each Newton step.
The entire model was implemented on a Sony Playstation
3 and the direct solver at each Newton iteration step
exploits the parallelism in the Cell Broadband Engine to
improve performance. The parallelized direct solver outperforms
state-of-the-art dense and sparse solvers running
on an AMD Opteron 246-based workstation. |
