Title:
SYSTEM FOR SHIELDING EXTERNAL ELECTROMAGNETIC PULSE ATTACK OF ELECTRIC MOTOR CONTROLLER OF ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/190569
Kind Code:
A1
Abstract:
A system for shielding an external electromagnetic pulse attack of an electric motor controller (60) of an electric vehicle comprising a shield body (16). A first helical conduit (77), a third helical conduit (84), a fifth helical conduit (91), an eighth helical conduit (102) and a tenth helical conduit (108), mounted at the exterior of the shield body, block an external electromagnetic field from directly entering the interior of the shield body. A signal line, a control line protector (22), a first power source surge protector (28), a second power source surge protector (36) and a third power source surge protector (40) are mounted inside the shield body to shield the external electromagnetic field depending on the shield body. The system can prevent an electric motor controller of an electric vehicle from suffering interference of an external strong electromagnetic field.
