Abstract
With more advancements in the electronic field, there is an increase in the demand for better energy systems to power mobile technology such as robots, UAVs, vehicles, etc. These electronic systems are evolving to satisfy different use cases with more powerful and sophisticated components which leads to an increase in the required energy needed to perform their given operations. Research is being made into methods to improve the energy density capabilities of current battery systems and create newer and more efficient systems as well as new technologies for optimal and safe operations. In this study, we review the current state of batteries in applications, safety techniques used for ensuring battery safety, and techniques and algorithms implemented for recharging procedures. In addition, we explore a battery recharging solution for a system of ground robots. These robots are deployed to perform certain tasks and will require battery recharges after an elapsed period to continue performing their tasks. A battery swapping recharging system is discussed in this paper to service the deployed ground robots, thus eliminating the need for manual recharging for each individual robot. The system also eliminates the need for an optimal charging dock location for the robots since they are no longer burdened with the need to periodically recharge during their task cycles. In this study, we design and implement a network-connected battery swapping platform that can use external batteries to recharge a UGV and incorporates a battery management system to monitor and track the battery state of charge.
