Abstract
Today, the question is no more: «Why 42 V?» but «When?» and «How?» and the introduction of dual voltage power networks in high luxury vehicles seems immediate in a short timeframe.
New technical and economical challenges have arise, not only to the current products and technologies used in the power distribution and control systems in vehicles; but also to the whole architecture approach (high power distribution, safety-protection, EMC compliance, energy management, system monitoring, components cost, x-by-wire functions, etc).
Safety becomes critical in a system with a high voltage (up to 58 V in load-dump condition). The aim of this paper is to present new failure situations as a result of having a dual voltage electrical network with higher voltages- in future vehicles electrical architectures. It requires defining new protection strategies to assure, at least, the same level of protection of 14 V vehicles.
