Comprehensive E-Mobility – What is feasible and what makes sense?
Dr Karsten Wasiluk, Assistant Director Automotive & Transport, Schlegel und Partner, Germany
Electric driving range and fast-charging capability are the dominating topics in regard to electric mobility. Batteries with capacities of 100 kWh and more as well as charging with 350 kW at 800V are discussed. The goal of these developments is the perfect substitution of today’s combustion vehicles as the central means of private mobility for all purposes. Accordingly, common scenarios of future mobility propagate an asymptotic development towards pure electric mobility.
The presentation discusses the question whether this projected development can be realized on an economy-wide scale and if it is adequate to achieve a fast and comprehensive decarbonization of the transport sector. We determine the requirements for electric mobility in regard to electricity demand for driving and resources needed for the production of battery electric vehicles themselves and discuss whether these demands can be met. In contrast to the all-purpose BEV, alternative scenarios with differentiated, single purpose vehicle types and multi-modal usage of different means of transport are presented. Using typical usage profiles, the costs and CO2 emission reduction potentials are compared and various questions discussed: How large is the CO2 reduction potential of a pure BEV compared to a PHEV during every-day use and which kind of mobility approach offers the highest emission reduction
potentials for the society as a whole? Is pure battery electric mobility ecologically necessary and economically reasonable? Or would a combination of 80% electric mobility combined with 20% combustion based driving, perhaps using natural gas or BTL fuel, make more sense? Based on these considerations, the effects on the automotive industry and its suppliers will be illustrated and discussed.
What is new?
This presentation looks at electric mobility not from a single vehicle’s point of view but with a focus on macroeconomic feasibility, ecological requirements and economic practicality.
