Performance for long and can even begin to smoke and catch fire. However, if not charged or used properly, they can’t provide peak Than other types, so they’ll hold a charge longer when not in use. Voltage per cell, so they can power the drone’s on-board systems withįewer cells than other rechargeables. Lithium polymer (LiPo) batteries are among the most commonīattery types used for drones because they offer the advantage of highĮnergy density in relation to their size and weight, with a higher Obviously, drones require on-board batteries to power their Protecting the battery and charging circuits Subsystems and some of the most common circuit protection components forįigure 1 Drone sub-systems that require circuit protection. Some of the areas that drone makers must take into account whenĭesigning circuit protection for their products’ various electrical There is a growing range of tools and techniques for implementing battery safety systems, as well as protection for electrostatic discharge (ESD).įigure 1 illustrates a generic drone design that highlights A battery that catches fire during charging and a fault in mid-flight represent a series of electrical problems that justify the choice of a robust electrical protection. Imaging and data collection, including emergency and rescue operations.Īll drones are subject to fault conditions that can cause various problems. The Federal AviationĪdministration foresees a continuous strong growth of products for aerial Of drones on the market is continuously increasing.
