I don't really understand what problem they're trying to solve. Contacts don't really wear out if they are tightened correctly and there was definitely no need for this on the 3-phase side of the driveline.
But you add induction coils like this and you're nearly going to need a medium as big as the motor itself to transfer that energy over an air gap.
It's also dumb to say 'no wear, we removed the last interface!!'. The motor is full of bearings. It actually seems to have twice as many bearings as a normal motor. So yes, you will need to replace all those bearings and it will be a right pain compared to just tightening a bolt for each of the phases.
