ABSTRACT
The German Aerospace Center
has merged a wide range of technological research and development for future
cars in a project called “Next Generation Car”. Within this large research
project, three vehicle
concepts for different applications (urban, regional and interurban) and with
different powertrains (fuel-cell, battery and hybrid) will be developed.
Research questions on different levels from conceptual question about vehicle
modularity down to detailed technological aspects like combining hydrogen
storage with cabin climatization and a systematic investigation of different
thermal energy storage systems for electric vehicles concepts are covered by
this project. To the latter, the contribution shows an overview about three
thermal storage technologies—sensible solid media, metallic latent and
thermochemical thermal energy storage systems—and details about the development
of an electrically
heated (power-to-heat) solid media storage system to achieve high storage
densities and to allow flexible thermal discharging values. Central works
target the identification of suitable thermal management solutions in future
electric vehicle concepts to increase range, efficiency and flexibility.
KEYWORDS
Energy management, thermal energy storage systems, power-to-heat, solid media storage, high thermal energy density.
