Fast charging uses up to 1000 V DC, and the current limits of conductors are typically set by the temperature it reaches when conduction losses heat them up. This can be (and is) offset by liquid cooling, allowing current installations to deliver up to 650 A (Tesla supercharger v3).
As far as I have understood, the license is not per game and is renewed in some interval. So once the current license expires for your company, you're on the new license, and will need to pay if you sell a copy of an older game.
I recently had an issue that happens on one out of between ten thousand and a hundred thousand interactions between two embedded processors. Thank god for logging!
