This is part of Volvo's new engine design (see http://autoweek.com/article/car-news/volvos-new-electric-sup...) And it is a valid question if it is a 'super' charger or a 'turbo' charger. I go with 'super' as the motor powers a generator which provides the electric power in concert with batteries. However if the batteries are simply charged braking action (regenerative braking) and then that charge is used to provide the low RPM compression boost its kind of a turbo and kind of not. (otherwise wasted energy being recycled for better engine performance). I'm guessing that an thermoelectric intercooler doesn't provide as much improvement but it would be fun to have both working together.
