The module is compact and can be installed in about an hour. The use of the module also prevents the battery from deep cycling, extending the life of the battery. Potential applications outside the transportation sector include power quality (e.g.,

However, the authors note, to date EES (almost exclusively pumped hydroelectric storage) contributes to only about 2% of the installed generation capacity in the United States. This type of application requires high round-trip energy efficiency and a long deep-cycle life, along with low operation and maintenance costs.
