Big in Energy and just 80mm in height: Next generation battery electric vehicle batteries: A study on future fully body in white integrated underfloor battery systems with focus on energy density and installation height

摘要

The global demand for battery electric vehicles in the sedan segment - which provide more comfort and performance while offering the same low-slung, sporty seating position is growing at a fast pace. This study aims at battery electric vehicles (BEVs) which require batteries that can be integrated into the limited installation spaces given to offer the driving comfort of conventional sedans or coupes. This study presents a battery module and battery pack with a total z-height of 80mm. It covers answers for the cell selection, much needed solutions for thermal management, E/E components and structural battery design.
