48V on-board power supply as mild hybrid system (UniTrain)

An on-board electrical system running at 48 V gives vehicle manufacturers a cost-effective way to lower CO2 emissions from vehicles, as well as introducing powerful new technologies into cars and lorries. Use of 48-V lithium-ion batteries in parallel with a traditional 12-V on-board network, does however mean that a whole new voltage level is introduced into motor vehicles, which also means new challenges for mechanics in vehicle workshops. It is often forgotten that some systems assigned to a 48-V network could also come into a high-voltage category under certain circumstances. This specifically applies, for example, to the three-phase motors used in active roll stabilisation systems.

Vehicle mechatronics technicians then not only need to know about the design and networking of a such an on-board sub-network, but also all of the safety regulations needed to ensure safe and professional working. In order to meet these new demands, we have developed a suitable new UniTrain course.
