The Modified Kinetic Battery Model builds on the regular Kinetic Battery Model, adding the ability to model several important phenomena:
- Rate-dependent losses
- Decreasing performance as the component degrades*
- Reduced capacity at cold temperatures
- Cycle lifetime with depth of discharge (DOD)
- Increased degradation rate at high temperatures
*In order to model decreasing performance of a storage device as it degrades over its lifetime, you also need the Multi-Year Module. Normally, HOMER simulates only a single year, and then extrapolates to calculate economics over an entire project lifetime. This makes HOMER fast and powerful for optimizing your system's architecture, but it assumes that every year will be exactly like the first one. The Multi-Year Module allows you to simulate all years in a project lifetime explicitly.
