High Voltage Light Vehicles Diagnosis & Repair Trainer
In the field of modern automotive technology, electromobility is increasingly coming into focus. As a trend-setting innovation, this drive technology is constantly evolving, making continuous qualification measures for specialists indispensable. Anyone who wants to keep up with the dynamic changes needs sound training and further education in order to stay up to date at all times. This training system significantly enriches the learning landscape, especially in the area of hybrid and electric vehicles, as it combines practical exercise scenarios, the highest safety standards and targeted theoretical approaches into a holistic, future-oriented concept.
