Sensata debuts GTM bidirectional contactor series for EVs

Sensata's GTM series of contactors are designed to deliver cost savings for EVs and equipment.

Sensata Technologies announced the launch of its Gigavac GTM400 and GTM500 bidirectional contactors for applications up to 1500 Vdc and 400A and 500A. The new contactors are ideal for high-power applications requiring reliable switching and DC circuit protection like energy storage systems, fast charging stations, and heavy-duty vehicles. According to Sensata, the new GTM series offers:

  • Increased current carry capability (reduced size and weight, increased battery life);
  • Best-in-class break performance (improved safety);
  • Advanced arc suppression performance (increased reliability and product life);
  • Unmatched short circuit performance (no rupture or fire risk);
  • Significant performance/cost ratio when compared to other available technologies.

“These new contactors highlight Sensata’s expertise in glass-to-metal technology and our ability to develop new, innovative solutions that offer competitive performance and value for electrified applications,” says Justin Colson, vice president of clean energy solutions at Sensata Technologies. “Our vision is to expand the GTM product family for lower power applications such as AGVs, material handling equipment, 2- and 3-wheeled vehicles and other EVs.”

In addition to the new GTM400 and GTM500, Sensata showcased its solutions and components that make batteries and charging infrastructure safer, cleaner, more efficient and connected at the Battery Show North America in Novi, Michigan, in September, the company said. The exhibit included a variety of contactors and fuses from Sensata’s Gigavac brand, Battery Management Systems (BMS) from Sensata’s Lithium Balance brand, Current Sensors and Insulation Monitoring Devices.

At Auto China 2024, CATL unveiled Shenxing Plus—an LFP battery that achieves a range above 1,000 km. (approx. 621 miles) with 4C superfast charging. CATL said the cathode of Shenxing Plus is made with a granular gradation technology, which places every nanometer particle in a position to achieve ultra-high compact density. The company adds its proprietary 3D honeycomb-shaped material to the anode, which it said boosts the energy density while effectively controlling the volume expansion during charge and discharge cycles. According to CATL, the single-piece casing also optimizes the internal space utilization, allowing the Shenxing Plus cells to reach a high energy density level. At the system level, the company said its Shenxing Plus battery pack has a topological structure optimized on top of module-free CTP 3.0 technology, enhancing the packing efficiency by 7%. The Shenxing battery system's energy density surpasses the 200 Wh/kg threshold for the first time, reaching 205 Wh/kg, making ranges over 1,000 kilometers a reality.
