Mydesign, in this particular instance, it was simulation to validate reliability of a traction inverter. The simulation showed there were reliability issues. Upon making changes, a further simulation proved out reliability. But that was just one instance. They were doing tests up and down the power system, including making sure the electrical power system did not interfere with the electronics in the cab of the vehicle.

Someone -- automaker or tier-one -- will have to focus on the electronic complexity problem. I don't know whose realm it falls under (automaker or supplier), but they're going to have to figure out how to reduce the 70 lbs of wiring and the number of MCUs in every vehicle. Seventy or 80 MCUs is too much.

What will it take to make a monumental effort if a grid overhaul in the USA? Another depression, which created much of the early infrastructure of the past, the canal, state park art, etc. Perhaps a sharp increase in prices.

What holds back progress in the states is the willingness to work on something without a payback. That is why we trail in internet speeds, tech innovation, and now EV support.

The USA spends around $500 billion on gasoline a year, according to the Los Angeles times. Switch to EV and we only spend 1/25 of that, on average ($20 billion). With the rest of that money, could we not start to upgrade the infrastructure?  


ps. I am OK with redundant processors.

"it was simulation to validate reliability of a traction inverter."

Rob, thanks for the clarification. So they are doing the simulation experiments at various levels for Power system reliability. Nothing concerned with the market demands like mileage or engine power. I think, they have to give much important to these type of issues.

I agree, Mydesign. It's quite amazing how much can be tested and validated virtually. While the process involves quite a bit of number crunching, the number crunching moves more quickly now, and it certainly beats building prototype after prototype.
