Battery - Business Research Insights’ Post

𝐏𝐫𝐞𝐯𝐞𝐧𝐭𝐢𝐧𝐠 𝐜𝐚𝐫 𝐛𝐚𝐭𝐭𝐞𝐫𝐲 𝐟𝐢𝐫𝐞𝐬 𝐰𝐢𝐭𝐡 𝐡𝐞𝐥𝐩 𝐟𝐫𝐨𝐦 𝐦𝐚𝐜𝐡𝐢𝐧𝐞 𝐥𝐞𝐚𝐫𝐧𝐢𝐧𝐠 One of the most critical safety concerns for electric vehicles is keeping their batteries cool, as temperature spikes can lead to dangerous consequences. New research led by a University of Arizona doctoral student proposes a way to predict and prevent temperature spikes in the lithium-ion batteries commonly used to power such #vehicles. The paper "Advancing Battery Safety," led by College of Engineering doctoral student Basab Goswami, is published in the Journal of #Power Sources. With the support of $599,808 from the Department of Defense, Goswami and his adviser, aerospace and mechanical engineering professor and project principal investigator Vitaliy Yurkiv, developed a framework that uses multiphysics and machine learning models to sense, predict and identify lithium-ion battery overheating, known as thermal runaway.   In the future, this framework could be integrated into an electric vehicle's battery management system to stop a battery from overheating, thereby protecting drivers and passengers, Goswami said. "We need to move to green energy," Goswami said, "but there are safety concerns associated with lithium-ion batteries." 𝐔𝐬𝐢𝐧𝐠 𝐭𝐡𝐞 𝐩𝐚𝐬𝐭 𝐭𝐨 𝐩𝐫𝐞𝐝𝐢𝐜𝐭 𝐭𝐡𝐞 𝐟𝐮𝐭𝐮𝐫𝐞 Thermal runaway can be extremely dangerous and difficult to predict.  "The temperature in a battery will escalate in an exponential manner and it will cause fire," #Goswami said. An #electric_vehicle_battery pack is comprised of closely connected battery "cells." Today's electric vehicles can have more than 1,000 cells in each battery pack.  If thermal runaway occurs in one cell, nearby cells are highly likely to heat, too, creating a domino effect. If that happens, the entire battery pack of the electric vehicle could explode, Goswami said. 𝐌𝐞𝐞𝐭𝐢𝐧𝐠 𝐚 𝐠𝐥𝐨𝐛𝐚𝐥 𝐝𝐞𝐦𝐚𝐧𝐝 Goswami's research was published at an important point in American car manufacturing history. In July, the same month the paper was published, the Biden administration announced a $1.7 billion investment in electric vehicle manufacturing across eight states. In 2023, global electric vehicle sales increased 35% from 2022. As demand rises, safety measures are essential to the #electric_vehicle movement, Goswami said. "Many people are still hesitant to embrace #batteries due to various safety concerns," he said. "To gain widespread acceptance, it's crucial for the public to know that ongoing research is actively addressing these critical safety issues."
