Model-Based Design of an Electric Bus Lithium-Ion Battery Pack

Abstract. This study details a framework for an iterative process which is utilized to optimize lithium-ion battery (LIB) pack design. This is accomplished through the homogenization of the lithium-ion cells and modules, the finite element simulation of these homogenized parts, and submodeling. This process enables the user to identify key structures and materials to be

A cell level design and analysis of lithium-ion battery packs

The world is gradually adopting electric vehicles (EVs) instead of internal combustion (IC) engine vehicles that raise the scope of battery design, battery pack configuration, and cell chemistry. Rechargeable batteries are studied well in the present technological paradigm. The current investigation model simulates a Li-ion battery cell and a battery pack using

Optimization of lithium-ion battery pack thermal

Numerical models, aiming to replicate observed thermal characteristics, often diverge from reality due to oversimplified assumptions. This is evident in the treatment of batteries as constant heat sources, overlooking their true operating conditions [14], [15] and neglecting electrical parameters [16], [17].Additionally, the exclusive focus on the active battery

Designing a Lithium-Ion Battery Pack: A Comprehensive Guide

Understanding the Basics Before diving into the design process, it''s crucial to understand the fundamental components of a lithium-ion battery pack: Cells: The basic building blocks of a battery pack. Lithium-ion cells come in various shapes (cylindrical, prismatic, pouch) and chemistries (e.g., NMC, LFP).

Battery Circuit Architecture

battery pack is removed from the system while under load, there is an opportunity for a damaging transient to occur. The battery pack should have sufficient capacitance to reduce transients or have something to clamp them. An even greater danger exists if there is a momentary short across the battery pack. The Li-ion safety protector may
