“We describe our eSupercharger as a next generation product because it is the first to deliver continuous high level boost, [not] intermittent operation,” states Aeristech CTO Bryn Richards.
“This allows vehicle manufacturers to simplify their boosting systems and to fully optimise the mechanical turbocharger for power or efficiency without lag ... to improve powertrain efficiency.”
Richards explains that Aeristech achieves continuous boosting with its eSupercharger by overcoming the thermal management issues that typically dog electric boosting devices.
The company uses permanent magnet motors in place of conventional switched reluctance technology and has engineered out cost by developing a patented control and switching system based on low cost components.
The prototype eSupercharger completed more than 400 hours of back-to-back testing, amounting to several thousand cycles of a wide range of operating modes.
The next stage is to install the system on an evaluation vehicle.
