These use electric motors to spool up the turbo at idle and low
speeds, so it's putting out boost pressure right from the start. The
objective is the same, to eliminate turbo lag.

Those are not really the same thing. The first one is an axial fan
that provides 1 psi of boost. The second and third are just electric
centrifugal superchargers.

As for electric superchargers, Garrett (now Honeywell) has one that's
either in production or about to go into production. There have been
several of them over the years, but none of them come close to the
Honeywell unit in terms of practicality. The electric fan and
supercharger listed in your links are not in the same league.

What these "electrified" turbos are about is bottom-end boost with
turbo fuel efficiency. The electric drive is just for low rpm.
Otherwise, it's a regular exhaust-driven turbocharger. It's not an
easy problem to solve. But two of the world's top Tier 1 suppliers are
close to market with their versions, so we'll see something pretty
soon.
