Victron Peukert Calculator
The Victron Peukert Calculator is a vital tool used in assessing a battery's capacity based on various parameters. Understanding how this calculator works can significantly aid in optimizing battery performance and determining its capabilities accurately.
Formula of Victron Peukert Calculator
The Victron Peukert Calculator utilizes the following formula to compute the capacity (Ah) of a battery:
Capacity(Ah) = I × (T / ((V^P) × K))
Where:
- Capacity (Ah) represents the battery's capacity in Ampere-hours (Ah).
- I stands for the discharge current in Amperes (A).
- T signifies the discharge time in hours (h).
- V denotes the battery's nominal voltage in Volts (V).
- P represents the Peukert exponent, a dimensionless constant typically between 1.0 and 1.3 for lead-acid batteries.
- K is a constant factor derived from the specific battery chemistry and manufacturer's data.
Understanding each variable's significance within this formula is crucial in accurately evaluating a battery's performance under different conditions.
