Function and Applications

Description:

This product teaches students the physical and technical foundations and applications of different battery technologies. The highly-topical issue of electric mobility is explored with an electric model car. Dimensioning and application of different battery types are just as much a topic as life expectancy or charging methods. The characteristics of various battery types are analyzed with qualitative and quantitative experiments. The product is expandable with a Lithium-Polymer and a lead battery module. Considering the storage problems with renewable energies, these topical issues should find their way into the curriculum.
