UniTrain Course – Electric Drives in Hybrid & Electric Vehicles

ABOUT THIS PRODUCT:

With the UniTrain course “Electric drives in the motor vehicle” you get the perfect introduction to the subject of hybrid and electric motor vehicles. The trainee assembles his or her own electric drive from a variety of components and then puts it into operation. Thanks to individual components coming from the areas of “energy conversion” and “drives”, the most important material is presented clearly and understandably thus facilitating rapid and efficient understanding and learning. In addition to all the technically important subjects (HV battery, inverter, synchronous and asynchronous three-phase machines, recuperation, etc.), other topics are explored such as “work safety” and the intrinsic safety of electrical and hybrid vehicles. Many animations and images are included to assist in the learning process as well as hands-on, practical experiments which add practical skills to the theoretical knowledge already acquired. To round off the course, all the material is then tested by means of diverse knowledge tests so that the learning progress of each student or trainee can be monitored and advanced.
