42 V-PowerNets

The efficiency of today's automobile PowerNets is limited and widely exhausted and the introduction of new systems is becoming more and more difficult. An offered remedy is the introduction of a new voltage level of 42 V. Within the scope of the EUROMOTOR symposium, associated problems were discussed and special methods for the solution were presented. The book describes current as well as futuristic fusing and protection concepts of vehicle PowerNets. It presents the introduction of a new 42 V-PowerNet into automobiles, the description of components and fusing systems for wires and electrical loads, the treatment of problems such as short-circuits and arcs, as well as seizing preventive measures. By focusing on the substantial aspects, the book addresses developers such as practitioners, who are active with automobile suppliers and vehicle manufacturers. Companies occupied with fusing devices, semiconductors, trunk circuits and electrical and/or electronic consumers will find this book especially interesting.

Discusses problems, their handling and solutions emerging from the intensively discussed 42-volt technology Coherently organized volume based on a workshop for industrial and academic experts Edited by researchers from one of the leading institutes in automotive technology Includes supplementary material: sn.pub/extras

Klappentext

The efficiency of today's automobile PowerNets is limited and widely exhausted and the introduction of new systems is becoming more and more difficult. An offered remedy is the introduction of a new voltage level of 42 V. Within the scope of the EUROMOTOR symposium, associated problems were discussed and special methods for the solution were presented. The book describes current as well as futuristic fusing and protection concepts of vehicle PowerNets. It presents the introduction of a new 42 V-PowerNet into automobiles, the description of components and fusing systems for wires and electrical loads, the treatment of problems such as short-circuits and arcs, as well as seizing preventive measures. By focusing on the substantial aspects, the book addresses developers such as practitioners, who are active with automobile suppliers and vehicle manufacturers. Companies occupied with fusing devices, semiconductors, trunk circuits and electrical and/or electronic consumers will find this book especially interesting.
