How many fuses does a Tesla Roadster inverter actually need? Here's what I found

EV inverters handle serious fault currents, and their protection architecture is more elaborate than most engineers expect.

This teardown of a Tesla Roadster 1.5 power electronics module shows a full bank of fuses, relays, contactors, and large fuses handling the heavy current paths.

For those designing automotive inverters, how do you approach the tradeoff between protection redundancy and system weight or cost?

Going to make a video on this board. What do you guys like to see in the video?

I received this board from ADI to create a video on it to eventually promote their product. What is that you will like to see on the video?

This is LT7170-1-AZ Eval board that acts as a buck regulator to deliver low voltage (1 V) high current (upto 20 A), useful for FPGA applications.

Most EV teardown content focuses on the cells. This one goes a level up and looks at how the battery pack actually interfaces with the rest of the vehicle.

This teardown shows all three connector systems on a Tesla Model S pack out of the car: the 400V high-current blade connectors that feed the drivetrain, the low-voltage CAN bus connectors that carry signals to the vehicle's computer, and the quick-disconnect cooling jackets that circulate glycol for thermal management.

If you are new to EV systems, which interface surprised you most: the 400V power connector, the CAN bus, or the glycol cooling?
