EV1/EV2/EV3: Electrical Vehicles Installations Safety (ADK: D-5/700)
Get know how and instructions about latest situation in e-mobility and the actual regulation. UNECE regulation No. 100 about details of safety requirements for the electric power train or road vehicles and ECE R100 Rev2 about European requirements for the approval of road electrical vehicles specifies all tests that must be carried out on lithium batteries installed on EV. Get equipped with knowledge about electrical safety, quality and operability. Practical knowledge, experiences, inspections, testing, measuring and reporting are crucial to lower the risks and fulfil the appropriate level of safety and quality according to standards and / or directives HD 60364- 6. On the practical example of MI 3333 EV Training Vehicle, we will learn about electrical safety testing devices, perform all necessary measurements, safety precautions and working energized procedures.
