Economic Analysis of Potential Secondary Use of Batteries from Electric Vehicles

Abstract

This article focuses on the practical use of used batteries from electric vehicles also known as 2nd life batteries. The first part emphasizes lithium batteries, which describes the overall life cycle of the battery, its number of charging cycles and secondary use. This part of the article also focuses on implemented projects of 2nd life batteries from electric vehicles and there is an analysis of the market potential for 2nd life batteries mentioned at the end of the chapter. The second part of this study offers a practical proposition of two possible strategies for using 2nd life batteries. The main source of income in both cases is the provision of regulatory energy. Using the formulas and the function of the calculation model created in the MS Excel software, the appropriate price of the battery for car manufacturers will be calculated and from other possible scenarios of individual strategies will be expressed. The first strategy works with large central battery storage and the second strategy uses small, decentralized battery storage with a fast-charging station.
