According to ANSYS Inc. Lead Engineer Xiao Hu, Ph.D., advanced numerical simulation helps accelerate the development of safe, long-lasting and cost-effective batteries for EVs. "One of the major concerns in the development of lithium-ion battery packs for EVs is thermal management. The temperature of all cells must be strictly maintained within a few degrees C across the entire pack. Cells are vulnerable to overheating from rapid discharging, overcharging or excessive ambient heating. Such overheating and uneven temperature distribution can lead to rapid cell degradation and shorten battery life. In extreme cases, thermal runaway may occur in a cell as heat builds up uncontrollably, possibly causing catastrophic destruction, such as fire and explosion."
