Technical FAQs 4

What is a second-life battery used for?

Potential uses for second-life batteries include CBS, EV charging stations, mobile energy storage, streetlamps, uninterruptible power systems, and residential energy storage.

Are Second-Life Electric Vehicle batteries useful for energy storage?

The manuscript reviews the research on economic and environmental benefits of second-life electric vehicle batteries (EVBs) use for energy storage in households, utilities, and EV charging stations.

Are battery electricity storage systems a good investment?

This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.

How much does a second-life battery cost?

The difference in conclusions in the studies reflects different input assumptions. For example, Steckel and colleagues 82 assumed a second-life battery cost including repurposing cost of $117/kWh while Kamath’s team 74 assumed $65/kWh. For new batteries, Steckel and colleagues 82 assumed $151/kWh while Kamath and colleagues 74 assumed $209/kWh.
