A couple of weeks ago, I did an interview with Jack Cheng, the CEO of the EV Open Platform MIH Consortium. I had a great conversation with him about his history in electric vehicles and the EV industry as a whole. Check it out.
In 2018, Tesla inverted our expectations and shook the EV industry when they adopted an ST Microelectronics silicon carbide-based inverter for their new Model 3 Electric Vehicle.
It allowed Tesla to shrink one of an EV's most critical components in half. And it has sparked new interest in a silicon technology as old as the industry itself.
Silicon carbide exists in meteorites but almost nowhere else naturally. Almost all of the silicon carbide in the world is synthetically made. It is a really beautiful rock. I love rocks.
While looking for a way to make artificial diamonds, he heated silica rock and powdered carbon - called coke - up to 2600 degrees Celsius in an electric furnace. This resulted in coarse grains of silicon carbide. His method is still used today in industry - the Acheson method.
