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.
clarified the importance of batteries in the development of the NEV industry. In 2009, the state promote 10 new cities and 1,000 new energy v ehicles for each city every year. Since then, China's NEV industry has entered a period of ra pid development. just like Figure 1 shows. Figure 1. NEV Sales and Battery Installed Capacity increase of 45.8%.
While the duty-cycle used is a common experimental technique, the novelty of this study is in the diversity of module- and pack-level EV battery samples evaluated and compared in a common grid energy service test regime using both energy and thermal performance metrics.
While the Model S batteries gave notably lower usable energy capacity than the other batteries, Fig. 5 b shows that the energy density of the Model S batteries was 2.01 times higher than the average of the other five batteries at the 4 h rate, and remained 1.81 times higher at the 1 h rate.
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
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).
