BONUS: The Tech Sheet (Pt2) - Why Do Cutting Edge EVs Still Have A 12 Volt Battery?
About this episode
Exploring the necessity of 12-volt batteries in modern electric vehicles, this episode delves into Tesla's push for a 48-volt architecture, particularly in the Cybertruck. It discusses the historical context of battery systems, the advantages of higher voltage—like reduced weight and improved efficiency—and the challenges of transitioning from 12 volts. Notable insights include Tesla's collaboration with suppliers and the broader implications for the automotive industry, highlighting the complexities of supply chains and the cautious approach of legacy automakers in adopting new technologies.
