Repurposing Retired Electric Vehicles (EV) Batteries

I&T Wish Repurposing Retired Electric Vehicles (EV) Batteries
(REF : W-0139)
Matched I&T Solution Examination of Backup Generator using Retired Batteries from Electric Vehicles
(REF: S-0019)
Trial Project P-0050
Summary and Challenges

The capacity of battery decays with repeated charging and discharging. As the state of health (SOH) requirement of battery in electric vehicles (EVs) is comparatively higher, a small degree of decay would affect the functionality and use of the battery in EVs.

In view of the increasing popularity of EVs in the market, there is a pressing need to repurpose retired EV batteries. We would like to explore the second life of these retired batteries and investigate their potential applications, such as putting them to use in lower-demand electrical appliances.

Retired EV batteries suitable for repurposing should be identified, collected and examined for their capacities and potential applications.

Expected Outcome To explore second life of retired EV batteries.
Expected Trial Duration 6 months
