Paper Title
Estimation of Safe Operating Area for Electric Vehicle Battery
Abstract
In recent times, electric vehicles (EVs) have experienced battery pack failures due to various factors such as short
circuits, thermal imbalances, fires, and explosions. This research paper employs a machine-learning approach to estimate
lithium- ion batteries’ safe operating area (SOA). It explores the factors that influence battery safety levels and
discusses the safe operating area for charging and discharging based on real-time data. The Safe Operating Area
(SOA) concept is a critical consideration in the design, operation, and management of EV batteries, as it defines the limits
within which the battery can operate safely without compromising performance or endangering the vehicle. The
significance of SOA analysis for EV batteries and its implications on battery design, thermal management, charging
strategies, and overall vehicle safety. This paper specifically addresses the estimation of the safe operation of a battery
using ML in relation to voltage and temperature with respect to time. It emphasises the importance of understanding the
interplay between these parameters to establish safe operational limits.
