The world is turning to electric transportation to curb greenhouse gas emissions. The trend toward electric mobility forces changes along the automotive sector's entire value chain. The new vehicles on the one hand require a number of technically innovative components and systems to operate and on the other hand new infrastructure, business models and services. The only way to achieve this, is high-quality training and education at colleges, vocational schools and universities.
With leXsolar-EMobilty Instructor students can gain comprehensive knowledge of state-of-the-art electric mobility systems as well as the underlying technical concepts and components. Batteries and battery management systems, controllers and CAN bus as well as motor and power train concepts are only a few topics that are addressed with the practical training sessions of leXsolar-EMobility Instructor. To top it all, students can really drive and the combination of a powerful ride and lab experiments guarantees great learning success!
