CC Power
TOOLS
Charging Time Calculator
Estimate charging time over CC-CV phases using charger limits and battery C-rate constraints.
How this works
t = E / P, with CV taper after SOC threshold
Methodology
CC phase: t_CC = (SOC_target - SOC_start) × E_pack / P_charger. CV taper uses exponential decay model fitted to typical Li-ion charge acceptance above 80% SOC.
