Abstract
Standard battery testing procedure consists of discharging the battery at constant current. However, for battery powered aircraft application, consideration of the cruise portion of the flight envelope suggests that power should be kept constant, implying that battery characterization should occur over a constant power discharge. Consequently, to take advantage of existing battery discharge curves it would be useful to have a methodology that can extract a constant power discharge curve from a constant current discharge curve. The development of such a methodology for lithium batteries is described in this article.
Highlights
Battery powered unmanned aerial vehicles have experienced consistent growth in use and application
To implement the method and approach of [8,9], battery discharge curves are required at constant power, where the battery voltage and current vary
To use the method in [8], battery data is required for a constant power discharge, or a means is required to convert constant current discharge curves to constant power discharge curves
Summary
Battery powered unmanned aerial vehicles have experienced consistent growth in use and application. In [8], a method is developed to estimate the range and endurance of battery powered aircraft with validation of the approach presented in [9]. To implement the method and approach of [8,9], battery discharge curves are required at constant power, where the battery voltage and current vary. To use the method in [8], battery data is required for a constant power discharge, or a means is required to convert constant current discharge curves to constant power discharge curves. Such a technique is the focus of this article
