Mercedes-Benz follows in the footsteps of Audi and also passes the 48 volt: what is the advantage?

Mercedes-Benz has announced a project really ambitious, the completion of the electrification of its entire range of products, with hybrids, plug-in hybrids, electric, and even hybrid solutions for those vehicles that are not equipped with hybrid systems to use. What does that mean? It means that even in vehicles that are not marketed as a hybrid and in which their mobility depends only on the heat engine, there will be electric motors of support that will provide a extra efficiency. The problem is that according to the increase of the needs of the electrical components come into play new requirements on the electrical installation of the vehicle. The solution, to bet on facilities 48 volts as the that will use within some Mercedes-Benz, and as the who has already released Audi the and more powerful version of sports of the Audi Q7, the Audi SQ7 TDI.

why Mercedes-Benz will focus on an installation of 48 volts?

On the premises of 48 volts, a priori, all are advantages. We talk about a voltage four times higher than the 12 volts that are currently used, and which until now were enough to supply the electric components on-board.

With facilities of 48 volts it would be possible for the supply of components that demand more energy and also have recourse to facilities with a small section of wiring to withstand the same energy output. Thanks to this, you could also save weight because you have to keep in mind that the cabling that requires a modern automobile represents a weight negligible.


the interesting Thing is that these facilities are 48-volt, which will go on moving in the next few years, enable the employment of ever more sophisticated systems. The best example we have in the Audi SQ7 TDI of Audi, which has introduced in a production model of the electric compressor, with a system that guarantees to boost immediate, without delays, even when the exhaust gases do not exert sufficient pressure to facilitate the movement of the turbine of the turbo conventional.

What will Mercedes-Benz thanks to the installation of 48 volts?

* starting Engines more sophisticated and systems mild-hybrid that will allow the car to have a degree of ability to move, only and exclusively thanks to an electric motor, without the need of that between the operation of the heat engine.
* Energy recovery systems more efficient, with capacity to recover more energy in less time, and use more energy to support to the heat engine.
* Electric motors support, which will work in solidarity to the engine heat to ensure a push higher in certain situations.
* Travel in electric-only mode. Mercedes-Benz of moment speaking of the boot, and low-speed manoeuvring, for example parking. For a few meters the car could travel in electric mode, with a motor which in turn will facilitate the starting of the thermal engine. From manufacturers such as Volkswagen is already talking about, even, solutions, micro-hybrid, which would allow the car to “llanear” on the road by disconnecting the heat engine, working only the electric motor to maintain the speed.


What are the advantages of this technology compared to the hybrid that we knew about up to now?

since electrical solutions with a functionality very limited, and not as complete as the one which could offer you a Toyota Prius, do not require electrical systems and batteries as are present in a hybrid to use, or a plug-in hybrid. That is a great advantage, first in terms of costs, and second in terms of the engineering of the car, since batteries involve a volume precious, and represent a weight added negligible.
