Traffic and transport are responsible for about one third of the world’s energy consumption. To date almost all of the energy is provided by fossil fuels. Electromobility is a significant key to increase the amount of renewable energy utilisation in this area. Efficient electrical storage devices are fundamental for this endeavour.

This kit teaches the physical and technical foundations and applications of different battery technologies. 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 included storage types.

With the integrated ChargerModule batteries are always ready to use and battery charging methods can be addressed in experiments. Like the other products of the Ready-to-go line, the leXsolar-EMobility Ready-to-go amazes with its flexible and location-independent usability that doesn’t require any additional equipment.
