MIT team develops data-driven safety envelope for lithium-ion batteries for EVs

Green Car Congress

Researchers at MIT, with a colleague from Tsinghua University, have developed a safety envelope for Li-ion batteries in electric vehicles by using a high accuracy finite element model of a pouch cell to produce more than 2,500 simulations and subsequently analyzing the data with Machine Learning (ML) algorithms. —Li et al.

DOE estimates EV battery pack costs in 2022 nearly 90% lower than in 2008

Green Car Congress

The Department of Energy’s (DOE’s) Vehicle Technologies Office estimates the cost of an electric vehicle lithium-ion battery pack declined 89% between 2008 and 2022 (using 2022 constant dollars). The decline in cost is due to improvements in battery technologies and chemistries, and an increase in manufacturing volume.
