What?
The article discusses a recent study conducted by Recurrent and highlighted by the DOE’s Vehicle Technologies Office, focusing on the reliability of lithium-ion batteries in plug-in electric vehicles. The study reveals a significant improvement in the reliability of electric vehicle batteries in recent years, with fewer instances of battery failures outside of recalls.
So What?
The data from the study indicates that there has been a substantial decrease in battery failures in electric vehicles manufactured between 2011 and 2023, particularly after 2016. The advancements in battery technology, such as active liquid cooling and improved thermal management, have contributed to this improvement. The reduced failure rates signify enhanced durability and quality control in the manufacturing process, leading to a more reliable electric vehicle ownership experience for consumers.
What’s next?
Looking ahead, the article raises questions about the continued progress in battery reliability and whether the industry should aim for even lower failure rates in the future. It also highlights specific models, such as early Tesla Model S and Nissan Leaf cars, that experienced higher rates of battery failures. The article emphasizes the importance of ongoing research and development to further enhance the safety and reliability of electric vehicle batteries, ultimately improving the overall performance and sustainability of electric transportation.
