Aeristech announces 12v e-supercharger

0

Aeristech, has announced the development of a 12V electric supercharger system; eCharger. The new system makes use of Aeristech’s motor control technology to derive maximum pressure charging utility from the power available in conventional 12V vehicle architectures.

Designed to provide transient boost to support traditional mechanical forced induction systems, the 12V architecture enables the system to be integrated into existing driveline technologies. The product is currently in development, with validation testing set to begin in November 2016 and prototypes available for customer trials from January 2017.

The eCharger can spin at speeds of up to 80,000rpm and uses Aeristech’s patented switching technology to reduce the frequency of internal switching events by 60% compared to conventional motors, meaning a significant reduction in heat and improved efficiency on the basis of like-for-like electrical switchgear cost. More importantly, Aeristech is free to optimise the layout of motor magnets and windings without fear of overloading the controller with excessively high frequency requirements, leading to ‘significant’ savings in material mass and cost.

“Since launching the 48V eSupercharger in 2015, we have received significant interest from Tier 1s and vehicle manufacturers and been able to continually develop the technology,” said Richard Wall, Aeristech CEO. “We have considerably improved cost, reduced weight and more than halved the package volume of the product. Now the core technology is fully established we are diversifying the product range to include a 12v offering, also capable of steady state operation, to meet additional market needs.”

The 48V eSupercharger has completed more than 1600 hours of back-to-back testing at Aeristech’s in-house facility, undergoing more than 500,000 boost events during 28,000 test cycles of a wide selection of operating modes. These ranged from short-bursts of high-power and maximum speed to continuous power outputs for extended periods, all l of which were endured by the eSupercharger without a single fault.
