Design of Battery Management System for an Autonomous Underwater Vehicle

Energy Storage systems (ESS) have become an important aspect in the arena of electrical distribution. The capability to monitor, control and optimize the performance of battery modules has become a crucial part of such systems. This paper presents a method to create a Battery Management System compatible with an underwater set-up. The model consists of Lithium-Polymer (LiPo) batteries and uses State of Charge (SoC) estimation method to determine the battery characteristics. It also protects batteries from overcharging, over-discharging and overheating. Further, the BMS design offers passive cell balancing and incorporates swapping in case of over-usage of one of the battery module.
