Session Format: Informal talks
The number of electric vehicles (EVs) on the roads is growing rapidly. EV batteries today, almost exclusively lithium-ion based, can last about 10 years before they can no longer provide the required performance such as power and range. The batteries in EVs cost heavily in both production and recycling. Handling the retired EV batteries is thus important both for economic and environment (e-waste).
These retired batteries, though no longer roadworthy in the vehicle, still have considerable lifetime for renewable energy and smart grid applications where the requirement for energy and power density is not as stringent in vehicles and the environment are less harsh, e.g., to buffer the volatile nature of the energy output of renewable energy systems. The second-life use extends the life cycle of these batteries after their first life in EVs, improves the environment, reduces EV ownership cost by selling them for second-life use, minimize the virgin material exploitation, and reduces the cost of BESS in renewable energy systems through the reuse and remanufacturing process exists.
However, there are a number of barriers to overcome in the deployment of second-life EV batteries, including how to properly remove them from vehicles, transport, store, test, and select second-life them for storage applications; how to quickly and accurately identify the battery’s health conditions before and after deployment in the new application, e.g., grid storage; how to dynamically manage them so as to minimize degradation and optimize usage; and how to meet various standards related to fire hazardous mitigation/prevention, certification, permit, and safety. These issues can be addressed through different phase of product life cycle, e.g., design, manufacturing, operation, and recycling (i.e., end-of-life). This special session will take a thorough look at the reuse and recycle of electric vehicle batteries and power electronics.
