Charged EVs | Sensata launches STEV high-voltage contactors to enhance EV energy switching effectivity and security

Sensata Applied sciences has introduced the STEV collection of high-voltage contactors for battery electrical autos and plug-in hybrid electrical autos, positioning the components as high-efficiency switches with “sturdy safety” for contemporary electrified car platforms. Sensata says the collection targets OEM wants round security, effectivity, and integration in high-voltage energy architectures.

The contactors are high-voltage switches that open and shut {an electrical} circuit hundreds of occasions over a car’s life. In EVs contactors management energy move between the battery and methods such because the inverter and charger, making them a part of the car’s protecting structure and linked to security, effectivity, and reliability.

Sensata says the STEV collection scales from plug-in hybrid passenger automobiles to battery electrical pickup vehicles and Class 8 heavy-duty vehicles. This scalability can assist OEMs standardize switching know-how throughout a number of car traces to simplify integration and cut back growth time.

On design and qualification, Sensata says STEV contactors are customizable and based mostly on core switching know-how “refined over years of growth.” The collection is engineered to satisfy automotive security and high quality necessities, together with compliance with Superior Product High quality Planning (APQP) processes and different OEM certification necessities, for integration into international car platforms.

“We don’t simply manufacture parts. We engineer options with our clients, adapting our STEV contactors to the distinctive calls for of main OEM’s purposes,” mentioned Markus Schwabe, EVP, Automotive and Aftermarket at Sensata Applied sciences.

The STEV collection helps steady present carry rankings from 150 A to 600 A and “excessive short-circuit face up to functionality better than 20 kA,” enabled by airtight sealing and modular designs.

Sensata additionally lists low contact resistance and minimized warmth era, together with: single- or dual-assembly choices; bidirectional present functionality on choose fashions by way of non-polarity essential contacts; airtight ceramic sealing for arc containment and environmental safety (with IP67 ingress safety out there on particular variants); and electrical isolation specs together with coil-to-contact dielectric power as much as 3.0 kV and insulation resistance of 1000 M? at 1000 VDC.

Sensata provides high-voltage options by engineering and manufacturing websites throughout North America, Europe, and Asia to help in-region manufacturing and localization.
