Abstract

Calculated Discharge Curve Method (CDCM) Constant Resistive Load Algorithm (CRL Algorithm) is presented as the first detailed part of CDCM Initial Algorithm [6]. CRL Algorithm was evaluated to relate cell/battery performance to load intensity.Alkaline manganese cells LR 20-VARTA were discharged across constant resistive loads: 1.00, 2.50, 3.33, and 10 Ohm at room temperature. HP 3054 DL was used to record discharge data. The subsets of the recorded voltage-time ordered pairs were used to generate discharge time curves vs discharge voltage by CDCM Initial Algorithm. 3D discharge curves are shown as the orthogonal projections on: time-current, time-voltage, and current-voltage planes. The linear voltage-current relation is defined under nonsteady state discharging of galvanic cell.The new CDCM cell discharge characteristics: average current, average voltage, and average power were defined for constant resistive load discharging. The linear dependencies of final: discharge time (t), average current (Q/t), and average power (E/t) were recognized and used to interpolate discharge curves across the load intensity interval.The mathematical calculations were conducting on IBM PC using Microsoft Excel software.
