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.
Currently, an increasing number of EV manufacturers are considering the secondary use of EVBs. BMW and Nissan are expected to secondary use returned batteries as home energy storage (Ayre, 2016; Dalton, 2016). Chevrolet has set up an energy storage station using old EVBs at the General Motors facility in Michigan (Voelcker, 2016).
Charging-discharging losses and energy use associated with battery mass in EV were included. Use in ESS is battery transport to ESS site and charging-discharging loss. 50% of cell repurposed. SLB lifetime is 5 years. EVB with secondary use scenario results in 15% reduction of life cycle energy and carbon footprint.
Thereby, the application for the secondary use of EVBs can tremendously enhance batteries’ values of their entire life cycle, improving their economic and environmental benefits. After the secondary use of such spent batteries, those with less than 20% of their storage capacity can be disassembled and scrapped (Gu et al., 2018; MIIT, 2018).
At the same time, the economics of recycling may be compromised by low quality or high costs of recovered batteries, which leads to that the incentives for secondary use of retired EVBs have yet to be strengthened (Casals et al., 2017; Ahmadi et al., 2017) and makes the profit model for the battery secondary use industry uncertain.
