| System Main Relay |
 |
The system main relay connects and disconnects electric currents between the high-voltage battery and high-voltage system by controlling the contact of movable and fixed parts. It also shuts off the high electrical voltage in a collision to secure the safety of vehicle occupants.
DENSO's newly developed system main relay reduces operation noise by approximately 10 dB by using a structure that lessens the impact when a movable part comes into contact with a fixed part, without slowing the speed in shutting off the high electrical voltage in a collision. DENSO also reduced the number of components used in the product, making assembly easier. |
