For R2012b and later, there are shipping demos of ssc_lithium_cell_1RC and ssc_lithium_cell_2RC models. the LiBatteryElements package is also part of the shipping Simscape demo, so it's not included in the R2012b folder of the zip file.

Hi Mengjia - Unfortunately the errors you see are expected and the model will not work in R2010a or earlier. The early versions of Simscape lookup tables required all dimensions to be a minimum of size 4, and my demo model only contains 3 temperatures. It will work fine in newer releases, otherwise it might work if you add a fourth temperature to the data for each lookup table.

The R2012a folder contains files that use newer features that will only work on R2012a or later. I suspect that is the reason for the build error. The R2010b model should work in that version and up, however it is a little less tidy because the lookup tables were external to the custom Simscape language blocks.

Hi David,

Roughly speaking, change the Costar parameter (capacity at 0°C – I think units are either Amp-seconds or Amp-hours) to match the capacity you want. Other resistance parameters may be inversely proportional to the change in capacity, so if you cut the capacity by half you would double the resistances.

If you need a detailed match to a specific model of battery, it gets a bit more complicated. I offer consulting service to help teach techniques to match the model to measured data.
