Problem Analysis: Causes, Impacts, and Solutions LiPo Batteries in Drone Technology

Abstract

Abstract:Lithium Polymer (LiPo) batteries are the primary power source in most modern drones due to their high power-to-weight ratio and superior energy density compared to other battery types. However, the sensitive chemical characteristics of LiPo batteries make them susceptible to various forms of failure, ranging from swelling and capacity degradation to thermal runaway, which can lead to fires. This article presents a literature review of the main causes of LiPo battery problems in drone systems, their impact on safety and operational performance, and mitigation solutions that can be implemented at both the hardware and operational levels. The review shows that most failures stem from three main factors: overcharging/over-discharging, physical damage due to impacts, and exposure to extreme temperatures. The implementation of a Battery Management System (BMS), standard charging and storage practices, and regular inspections have proven effective in reducing the risk of failure and extending battery life.
