48 Volt Automotive Electrical System

The primary electronic units in the 48 volt system are a three phase inverter to operate the motor starter generator and the dc dc converter that ties the 12 and 48 volt systems together.

The latest specialist evs will be using components that more power additional torque and with automation and smart engineering greater intelligence. The potential applications of 48v are exciting representing a huge innovation in automotive design. In recent years we ve seen manufacturers add navigation systems upgrade audio and communication packages and utilize turbochargers or superchargers each placing a significant demand on the car s power grid. A 48 volt electrical system should work very well on 4wds because the power demands of 4wds are even greater than those of highly specified passenger cars.

Most modern vehicles have 12 volt electrical systems which power everything by means of the car battery. A major control center with 32 bit mcu oversees the whole system. Mercedes benz is also using 48 volt electrical system with its new straight six engine cars. Mild hybrid systems that use 48 volt components can increase fuel economy by up to 15 percent and cost 1 000 or less per vehicle.

If you think about it that was a natural next step. Odds are your next car will have a start stop system probably 12 volts. Sure it s not a novel idea. And because they can transmit much more electrical power at the same current as a 12 volt system automotive engineers can reduce cable thicknesses to save cost and weight.

Electric vehicle manufacturers are starting to adopt 48 volt electrical systems. The latest trend component associated with these advancements is the 48 volt electrical system. He says 48 volt systems use similar wiring to 12 volt systems with no need for special materials. That new 3 0 liter i6 from mercedes benz is entirely beltless meaning there are no belt driven systems.

Bosch continental delphi and valeo are among the key components makers working to provide 48 volt systems to automakers. An emerging automotive standard. In fact some cars already rely on this power system.
