Finally an interesting automotive development that represents another step in this direction.
For about 20 years the auto industry kicked around the idea of upgrading to a 36-Volt electrical system to replace the existing 12-Volt system, but nothing much came of it. Agreement on the upgrade was more complicated than the previous switch from 6- to 12-Volts. Higher-voltage hybrid and electric cars also made many question whether a new electrical standard was even needed at all.
Now it appears the auto industry is converging on a 48-Volt system which should be even better for the future of motorhomes. Auto manufacturers and their suppliers are acting to improve fuel economy (a lofty goal in itself), but to me the potential for improvement that an inexpensive high-capacity 48-Volt electrical system should offer motorhomes is much more interesting.
Best of all, they are talking about a cost premium in order of $1,000, leaving plenty on the table for added battery capacity compared to conventional generators. Please note I'm not suggesting these components are large enough to serve as part of a hybrid system for motorhomes, but rather will lead to affordable upgraded electrical systems that may not require the typical Onan for many RVers.
