Battery energy storage systems are increasingly used to stabilize and balance energy supply systems. For stationary applications, as UPS, electrochemical battery modules are often used, being Li-Ion and lead acid the most popular choice mostly due to power ranges, energy capacity and reversible capability. The present paper is focused in the design of a modular converter to boost the voltage of a Li-Ion battery module from 48 to 400 Volts, with a maximum power of 18 kW. The selected power converter topology is based on a DC/DC converter built by an interleaving synchronous rectifier (ISR) connected in series to a Three Phase Dual Active Bridge (TPDAB). The paper includes an study on alternative topologies, the dynamic average model for the selected approach, the control system design, the selection and implementation of a hardware prototype and the validation of the complete system using simulation under PLECs.

“…High voltage gain bi-directional DC-DC converter proposed in [10] is used as it results in the lesser value of ultra capacitor bank voltage (V in ), thus making the ultra capacitor bank compact in size. The high gain converter consists of two half bridges.…”

This paper presents the concept of electronic battery (e-Battery) for energy storage systems. The proposed e-Battery is a combination of ultra capacitor bank and power electronic converters. This paper looks at issues related to chemical batteries and proposes the concept of an e-Battery. The proposed e-Battery overcomes many of the drawbacks of a conventional chemical battery. The control strategy developed for the closed loop operation of the proposed e-Battery is also presented in this paper. The performance of the proposed e-Battery is verified through detailed time domain simulation in PSCAD/EMTDC. A hardware prototype is built to validate the performance of the proposed e-Battery experimentally.
