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.
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.
Tested a diverse set of EV battery chemistries, formats, and cooling systems. NCA has triple the energy losses of NMC but half the physical footprint. High-power cycling can be done 5x as frequently using forced-liquid cooling. New methods for ranking EV batteries by energy, volume, and 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.
Among the seven EV battery samples tested, Volt and EnerDel batteries (both from hybrid EVs using NMC chemistry) gave the highest usable energy capacity and energy efficiency, indicating the greatest potential for low-cost charging and high-revenue discharging in energy arbitrage.
Still, the top three battery makers are responsible for two thirds (66%) of the total battery deployment, which highlights the importance of scale in this business, in order to have the most competitive product on the market. Panasonic, once upon a time a leader in the automotive EV business, has continued its slow slide down the table.
