Plug-In Hybrid Vehicle Induction Motor Aerodynamic Noise Evaluation 2009-01-2148

Plug-in hybrid vehicles connect to the power grid while parked so they can operate on electricity from the grid as well as on petroleum-based fuel. This distinguishes them in a fundamental way from the plug-less hybrid vehicles currently produced or planned by auto-marker which rely 100% on the petroleum-based fuel. A plug-in hybrid can reduce emissions. However, the aim of this paper is to investigate experimentally the aerodynamic noise performance of a plug-in hybrid vehicle induction motor with the view of evaluation. For this reason, a special test rig was developed to simulate the motor aerodynamic noise source. The results indicate that significant information can be obtained for this source. This can be an effective way to control this generated noise and consequently reduce the vehicle interior and exterior noises and look promising.
