What is the SAMPLE RATE and how is it used?
The SAMPLE RATE is the result of multiplying the SMOOTHING value by the ratio of the “Nominal Amp Hour” to the “Charge or Discharge Amps”, then adding 1.0 to the product. CASP takes the “Nominal Amp Hour” and the “Charge or Discharge Amps” values from the battery parameter table being used. In firmware versions 6.x, CASP gets the SMOOTHING value from table 099. In firmware versions 7.x, CASP obtains the SMOOTHING value from table 098. The following equation shows how the SAMPLE RATE is calculated using these three values: SAMPLE RATE = 1 + ((Nominal Amp Hour / Charge or Discharge Amps) x SMOOTHING Value). The SAMPLE RATE determines how often the collected voltage data (measured once per second) is sampled. These samples are used in various calculations, one of which is to calculate the charge and discharge battery voltage curve (both graphed and ungraphed). The change, in the sampled battery voltage, is used to find the battery voltage curve’s slope (dv/dt). Finally, the slope values a
