How are EV batteries ranked?

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.

What makes a good battery?

Through a detailed evaluation of materials based on criteria such as thermal stability, mechanical strength, chemical resistance, and environmental impact, the research identifies materials that enhance battery efficiency, longevity, and vehicle performance.

How can EV battery performance scores be used for Energy Arbitrage?

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

Which battery has the best thermal performance?

The Volt battery also gave the best thermal performance thanks to its low energy losses and active liquid thermal management, allowing it to perform energy arbitrage at high power with minimal risk of accelerated degradation or thermal runaway.

How are battery performance metrics evaluated?

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).

Which battery has the most energy efficiencies?

All batteries gave energy efficiencies between 95% and 98% at the 4 h rate, while faster rates gave lower energy efficiencies and widening differences between chemistries. EnerDel-17 and Volt-15 (both NMC and hybrid EV) gave the highest energy efficiencies, maintaining about 97% at the 1 h rate.
