Abstract
An e-charger includes a shaft supported for rotation about an axis. The e-charger also includes a compressor wheel that is attached to the shaft. The e-charger further includes an electric motor configured to drive the shaft and the compressor wheel in rotation. Also, the e-charger includes a housing that houses the electric motor and at least part of the shaft. Moreover, the e-charger includes a dampening system incorporated in the housing and configured to dampen loads transferring through the housing. The dampening system includes at least one solid-state dampener that is resiliently flexible, and the dampening system includes at least one fluid viscous dampener.
