How is cycles defined in the battery block?

Are cycles defined as the ratio of current_throughput/nominal_capacity? This isn't called out anywhere, i just see the word 'Cycles'.

Hi Ryan,
For these two cell blocks: Battery Equivalent Circuit and Battery (Table-Based), the number of cycles is defined as discharge total throughput capacity divided by the cell capacity adjusted based on battery aging. The aging adjusted capacity is different from rated capacity or nominal capacity for fresh cells. If we write it in the time derivative form for cycle number Nc, it looks like:
