Measuring and Testing the Parameters of a Battery Pack Designed for Powering Unmanned Aircraft Systems at Various Temperatures

Abstract

This paper describes results of tests dedicated to studying – in simulated environmental conditions – operation of a battery pack designed for powering unmanned aircraft systems. In particular, the tests concerned determining the electrical parameters of battery packs, with and without radiators, during their operation in changing environmental conditions and resistance to large temperature fluctuations. Amicell, a high density lithium polymer battery manufactured by the Israeli Amit Industries ltd., was selected for testing. The test results present characteristics of the batteries tested in different temperatures and allow for designing and trying out proper battery protections against environmental conditions, with the intention to attain continuous and correct operation. The tests have been carried out in the accredited Environmental Test Laboratory which is part of the Department of Avionics of the Institute of Aviation in Poland.

Preparation and Implementation of a Test Flight of Lightweight, Unmanned Stratospheric Balloon with Gopro Camera Mounted and Analysis of Acquired Material

“…Other than satellite measuring methods, should be considered (barometric methods for example). To meet requirements of the specific mission it is also advisable to integrate various measuring methods [16], but this would be strictly dependent on load capacity of the balloon. The bursting of the balloon and the fall of the gondola, unfortunately, have not been recorded due to the low battery capacity in the camera and extremely low temperature conditions.…”
