The voltage rises


The idea of a higher vehicle electrical system voltage in automobiles is not new. As early as the 1990s, a 42V consortium was set up. However, due to a lack of standards, this approach was not successful. But now everything is to change.

Electricity used to be minimal in automobiles. They mainly ran mechanically. Electric windows? They didn’t exist. For this manually operated handles were used. Today, a whole host of electrical functions such as seat heating, comfort and assistance systems draw a lot of electricity from the battery. In a 12 V vehicle electrical system, higher and higher currents have to flow. To prevent this on-board network from surrendering, manufacturers are now installing a second, stronger network in the car in parallel – with 48 V direct current (48 VDC).
