New methods for ranking EV batteries by energy, volume, and thermal performance. Overall battery performance ranking depends heavily on project-specific constraints. Electric vehicle (EV) batteries can provide extended value beyond EV service if they are repurposed for a “second life” in electricity grid applications.
Test results are evaluated based on six battery performance metrics in three key performance categories, including two energy metrics (usable energy capacity and charge–discharge energy efficiency), one volume metric (energy density), and three thermal metrics (average temperature rise, peak temperature rise, and cycle time).
The performance of Li-ion batteries at beginning of life (BOL) has been presented in various studies, where the dependence of the battery performance parameters on the operating conditions was analysed [1, 8].
The overall performance scores can be used to rank all EV battery samples based on the constraints of specific second-life energy arbitrage projects. This tool can aid developers in the selection of EV batteries for energy arbitrage and similar grid energy services such as peak shaving. 4.1. Energy
In particular, the Licerion pouch cell (Sion) showed the best performance regarding range and capacity-to-weight ratio, while the 4680 cylindrical cell (Panasonic) and blade battery (BYD) was superior in capacity-to-volume and capacity-to-cost ratios, respectively.

Thermal performance of second-life batteries will depend on the thermal management system design of the EV battery, which can affect real-time power capability as well as long-term degradation and cell-to-cell uniformity.
