INDUGRID provides 4 free Battery & DC Systems engineering calculators for professional use. Battery capacity, charge time, Peukert correction, autonomy, DC cable sizing and UPS calculations for industrial DC systems.
Battery Capacity & Autonomy
Calculate required battery capacity for a given load and autonomy time, applying Peukert correction …
C_required = (I_load x t_auto) / DoD | Peukert: C_p = C20 x (I20/I)^(n-1)
Battery Charge Time
Calculate charge time for lead-acid, AGM and lithium batteries based on charger current and battery …
t_charge = (C x DoD) / (I_charge x eta_charge)
DC Bus & Cable Sizing
Size DC cables for battery systems, PV and DC switchgear based on current, voltage drop and temperat…
deltaU = 2 x rho x L x I / A | A_min = 2 x rho x L x I / deltaU_max
UPS Sizing & Runtime
Size an Uninterruptible Power Supply for critical loads and calculate backup runtime from battery ca…
kVA_UPS = kW_load / (PF x eta) | t = (C_Ah x V_bat x eta_inv) / (P_load x 1000) x 60
