Experimental Study of Parallel-connected Li-Ion Batteries for an Aquatic Reed Electric Harvester

Li-Ion batteries are used, nowadays, in many vehicle applications, including special vehicles with particular needs which can require several types of battery cell connections and configurations. Li-Ion battery packs are constructed from a large number of smaller cells connected in series and parallel respectively depending on the desired voltage and capacity. The paper presents a system designated to charge and discharge three battery packs connected in parallel and used on the aquatic reed electric harvester, where the main requirement was a high ratio between capacity and voltage for the total battery pack. The conclusions of this article can contribute to the improvement of electric vehicle power system design by configuring existing battery packs on the market.
