Audi cranks up power to 48 volts

Crank it up to 300V like ours and I'll be impressed. Still have a conventional 12V system like ours. I remember the electronics trade magazines back in the 90's (or was it the 80's?) were full of articles about autos going to a 36V system for everything. Guess that never happened.

I thought it was going to be 24v.

Found this.

 

"In automobiles, a 42-volt electrical system was an electrical power standard proposed in the late 1990s. It was intended to allow more powerful electrically driven accessories, and lighter automobile wiring harnesses. Electric motors were proposed to be used for power steering or other systems, providing more compact installations and eliminating the weight of drive belts or large wires for high-current loads."

"The SAE discussed an increased automobile standard voltage as early as 1988."

and this, interesting

"Whatever Happened to the 42-Volt Car?

The Higher the voltage the smaller the wire and less weight and cost. You probably can't get electricuted at 48v. :)

You can, it just isn't lethal. High voltage DC is considered 60VDC and higher in which case a whole bunch of design and bureaucratic requirements come into place driving up cost. This is why golf carts never use higher than 48V systems.
