PARAMETER REFERENCE
Cell and pack
parameter reference.
Explore nominal energy, current and ideal series/parallel relationships. Default inputs are illustrative values, not catalogue specifications.
Additional mass covers the hardware included within your chosen pack boundary. The energy share is a scenario assumption, not a calibrated SOC window.

IDEAL COMBINATION
Nominal pack voltage V
Pack capacity reference Ah
Nominal pack energy Wh
Mass including entered overhead kg
Cell nominal energy / mass Wh/kg
Pack nominal energy / mass Wh/kg
Entered C-rate current equivalent A
Nominal-voltage power equivalent W
Energy at the assumed share Wh
Mass boundary
What these calculations tell you
These are nominal-value calculations for identical cells. They do not determine permitted current, cell matching, thermal design, test approval or runtime. The manufacturer or customer confirms those aspects for the project.
The relationships used here
V_pack = N_s × V_cell Q_pack = N_p × Q_cell E_nom = V_pack × Q_pack m_pack = N_s × N_p × m_cell + m_hardware I_reference = C-rate × Q_pack P_nominal-reference = V_pack × I_reference
