leXsolar-EMobility Ready-to-go

Function and Applications

The future of road traffic belongs to battery-powered electrical cars which are about to establish themselves against other trend-setting alternatives like fuel cell-powered cars. The E-mobility set teaches the physical and technical foundations and applications of different battery technologies used in cars. Eight different battery types like lithium-polymer battery, capacitor or fuel cell allow for the study of characteristics like lifespan and charging methods. Qualitative and quantitative experiments are used to explore the properties of various battery types. The electric car can be run with all storage types. With the integrated charging module batteries are always ready to use and battery charging methods can be addressed in experiments.
