CALCULATORS / ELECTRICAL

Batteries and energy storage

Cell/pack data and stated electrical and thermal conditions.

usable capacity, voltage or discharge curve, load profile, efficiency → runtime range, reserve allowance

cell limits, target voltage, capacity and current needs → series/parallel counts, pack limits

capacity, nominal voltage, usable fraction → nominal and usable energy

output power, pack voltage range, converter efficiency → current range, peak demand

cell capacity, current, parallel count → C-rate, per-cell current

open-circuit voltage, internal resistance, load → terminal voltage, resistive heat

capacity, current, state-of-charge interval, taper assumption → bulk time, conditional full-charge time

usable energy, duty, life assumption → energy throughput, replacement sensitivity

capacitance, voltage bounds, load, ESR → usable energy, droop, approximate runtime

imbalance, bleed resistance, cell voltage → balancing current, heat, equalization time
