1500 Amps???

  Indeed. There's a crazy amount of current going through these things. Apparently the limit used to be 1200A, and beyond that, traditional fuses don't work well because the metal vaporizes and starts conducting electricity even after the fuse wire has melted. To get to 1500A they created a computer-controlled pyrotechnic fuse. That's what enabled the "ludicrous mode" that you can get on their high-end cars.
