Analysis of battery charging in the development of BMS for solar UAV application

Abstract

Solar UAV is an alternative technology for UAV to upgrade endurance and energy management of the UAV. PUSTEKBANG as an aeronautics institution in Indonesia also develops a project related to it. Providing research in Solar UAV field, there are some sub systems development to attain its applications, one of the most important elements is energy management system. Spesific experiments were carried out in order to improve the research development for switching process on parallel batteries. Further analysis will be conducted based of these tests related to Battery Management System (BMS) and Energy Management System (EMS). This paper presents the analysis of charging characteristics from two kinds of battery's capacity (3000mAh and 8000mAh) that have been conducted with variation of voltage inputs and two values of current inputs (2A and 1A). The result shows that when the battery is charged in 2A, time consuming for both types of batteries will increase 2 times in a row with the increasing of voltage input. Then, when the battery is charged in 1A, time consuming for both types of batteries is a little bit longer which is about 2.5 times in a row with the increasing of voltage input.
