Sensata launches high efficiency contactor for 400V/800V EV systems

SWINDON, United Kingdom - Sensata Technologies (NYSE:ST), a $4.55 billion market cap company currently showing positive momentum with a 14.48% gain year-to-date, has introduced its High Efficiency Contactor (HEC), a new solution designed to enable electric vehicles with 800V systems to charge at 400V charging stations without requiring boost converter systems. According to InvestingPro analysis, Sensata appears undervalued at current levels, suggesting potential upside for investors interested in the EV infrastructure space.

The contactor addresses compatibility challenges between newer 800V EV architectures and the existing 400V charging infrastructure by enabling battery reconfiguration between the two voltage levels. With annual revenues of $3.84 billion and a healthy EBITDA of $738 million in the last twelve months, Sensata has demonstrated its capability to develop and commercialize innovative solutions in the EV market.

According to the company’s press release, the HEC integrates three high-voltage contactor poles in a mechanically synchronized design that supports standard battery configurations while also allowing independent access to either of two 400V battery packs for functions like battery balancing and limp-home mode.

The system features a bi-stable design with no holding power requirements and contact resistance below 50 microohms, which the company states minimizes energy loss and heat generation. Sensata claims the HEC reduces component count by over 50% compared to traditional battery switching systems.

"Our HECs power safer, more efficient vehicles with seamless charging, making EVs more practical and accelerating the adoption of next-generation platforms," said Brian Wilkie, EVP, Vehicle Business at Sensata Technologies, in the statement.

The contactor is designed to support continuous currents exceeding 1000 amperes and includes real-time diagnostics through an integrated ASIL-D compliant position sensor. Sensata reports the device can withstand short-circuit events up to 25 kA and mechanical shocks over 90 g.

Beyond EV battery reconfiguration, the company indicates the HEC is compatible with Vehicle-to-Grid systems, Megawatt charging, and the North American Charging Standard.
