DEEP-DIVE 2+ HOUR WORKSHOP ON 48V AND ITS PLACE IN FUTURE EV POWER SUPPLY ARCHITECTURE

Just when the automotive industry thought the 48V story was over and western OEMs agreed that it didn’t make sense to have 48 volts on a battery electric vehicle because of too much legacy conversion, Tesla released its Cybertruck with 48V architecture and 12V modules. Tesla vehicles will have a downstream conversion from 48V to 12V.

With Tesla planning to produce all future vehicles with low-voltage power supply, what does it mean for the future of 48V? What is the room for 48V in an electric vehicle? Will the wider industry need to benchmark again, and can we make a business case for 48V?

• This deep-dive workshop sees leading power supply experts take the stage to re-investigate Tesla’s reasons for adopting 48V architecture for all its vehicles, 48V as a true power supply system, and its place in future vehicle architectures.

PANEL DISCUSSION

To deliver 800V power, wire harness thickness and protection also have to increase. But if increasing the diameter and thickness of the harness, increases the weight of the vehicle, this is not only a drawback for the vehicle’s mileage but also an added cost. How are OEMs going to safely high-voltage from the battery without adding more weight and cost?

• This is a big challenge right now and a question experts address in this panel.
