The use of stationary batteries in electric vehicle fast-charging stations is a well-known solution to alleviate stress on the grid. However, the rapid variations in charging demand pose a challenge to battery lifetime due to cycle aging. In this framework, the paper aims to evaluate the adoption of two different battery chemistries within the same storage system to cope with different demand dynamics (fast and slow power variations). The comparison is done by finding the optimal sizing for both the single and hybrid chemistry solutions and comparing their costs.

Abstract
The use of stationary batteries in electric vehicle fast-charging stations is a well-known solution to alleviate stress on the grid. However, the rapid variations in charging demand pose a challenge to battery lifetime due to cycle aging. In this framework, the paper aims to evaluate the adoption of two different battery chemistries within the same storage system to cope with different demand dynamics (fast and slow power variations). The comparison is done by finding the optimal sizing for both the single and hybrid chemistry solutions and comparing their costs.File in questo prodotto:
