Dennis Maller, VP of Engineering, Trombetta:
"Improving the Value Proposition of Line Contactors
for Electric Vehicles"
Significant benefits in total performance and economics are achieved with a
line contactor developed for modern AC Variable Frequency and DC PWM
controller based applications. This is in contrast with the traditional
approach of using a contactor developed for legacy applications where it
served as the primary power switch for motor start stop applications
characterized by high inrush and interrupt current requirements.
Modern electric vehicles utilize an electronic controller to manage power
transfer between batteries and drive motor. The DC contactor, typically
placed in series between the battery and the controller to allow battery
disconnect, is commanded to open and close while the controller is allowing
no current flow. Furthermore, many controllers are able to dynamically
manage power to the contactor coil. By working with Electric Vehicle
systems engineers to understand and capture these and other relevant
application details, the line contactor can be optimized for the
application. The resulting benefits are the elimination of material waste
where it does not add value while enabling improved vehicle reliability and
realized value by defining and incorporating features customers truly value.
