Abstract
A system and method is provided for electrostatic air filtering in automotive vehicles, such as electric and hybrid electric vehicles. The system includes an electrical distribution system and an electrostatic filtering system having discharge electrodes and an accumulation electrode. The distribution system is in high-voltage electrical communication with the filtering system as well as an electric motor and a high-voltage energy storage device in the vehicle. In operation, the distribution system distributes high-voltage electric power to the filtering system. The filtering system receives the high-voltage electric power to generate a high-voltage electrostatic potential between the accumulation electrode and the discharge electrodes to remove particulates from air flowing through a region of the electrostatic filtering system.
