Abstract

This paper presents a case study of developing a stationary battery energy storage system (ESS) with a combination of used batteries from different electric vehicles (EVs), The batteries having nonidentical specifications, dismantled from two models of retired EVs with varied conditions, have been characterized. The state of health and the expected electrical performance of these repurposed batteries from EVs are analyzed and compared. A modular battery ESS with dual feed configuration is developed to strike a balance between reliability, performance and the cost of implementation. The modular approach allows flexibility in capacity and voltage level manipulation, as well as mitigates the efforts of battery replacement. The construction and key components in the systems are illustrated and explained. A simulation study has been performed which explores the effects of varied battery profiles and combinations to system performance. This work provides insights on designing and operating sustainable stationary ESS with mixed repurposed cells.
