The Hybrid Energy Storage Project has a combination of ‘Worlds Smartest Lithium Batteries together with tubular gel batteries (lead acid variant) to achieve economic long duration backup.
This paper proposes a method for battery storage and supercapacitor (SC) hybrid operation toward improving EVs' performance. The adopted concept is established to regulate the level of charge for the SC to suit the immediate storage needs of the EV in such a way as to couple both storage devices. The results demonstrate that the current drawn from the battery has significantly reduced the discharging rate of the battery smoothed out compared to the EV without the SC. Also, the electric vehicle (EV) battery capacity is improved and the implementation of an SC eliminates the abrupt discharge of state of charge (SoC). The SC supports the EV by providing the necessary power when required. The simulation results demonstrate the contribution of SC to improving the battery performance and the reduction in discharging rate. The battery cannot be disconnected, while the SC could be, and power can be exchanged via supercapacitor. The SC is faster than the battery to maintain the optimum SoC

The output-power fluctuations from the wave energy converters (WECs) with a high peak-to-average ratio need to be smoothed out before supplying power to electric loads or power grids. Usually, short-term energy storage is used to smooth out the output-power fluctuations of WECs. In this article, a novel multi-filter-based dynamic power-sharing control is devised for a hybrid energy storage system (HESS) integrated with a grid-connected WEC. An advanced model of HESS-integrated WEC consisting of a direct-drive permanent-magnet linear-generator, a supercapacitor, and a battery system is developed to test the proposed multi-filter-based dynamic control strategy. The distinguishing features of this study are: 1) the power-sharing strategy is based on a dynamic-filter that is designed to change its corner-frequency depending upon the incoming ocean wave, 2) the low and the high-frequency power-components are allocated based on ocean wave conditions, 3) the proposed strategy is suitable for
