Sensata Technologies, announced its new High Voltage Junction Box solutions provide safe and reliable protection and power distribution for high power charging of commercial electric vehicles. The solutions include DC Charging Boxes that support megawatt charging of medium and heavy-duty electric trucks up to 850 Volts and 1300 Amps.
Combining Sensata’s proven contactor, fuse, and controller technologies into a compact package, the new High Voltage Junction Boxes are custom-designed for specific vehicle requirements.
Driven by the need for fast charging, electric vehicle manufacturers require systems that can handle higher charging power levels. “We have successfully optimized our contactor and fuse design to meet the increased thermal performance that megawatt charging requires while keeping within tight space constraints,” said Brian Wilkie, Vice President, Heavy Vehicle & Off-Road at Sensata Technologies.
According to Mr. Wilkie, “Sensata’s unique capability to design all the safety-critical components of the solution (like contactors, fuses, control boards, and software) in-house was instrumental in securing new strategic agreements with industry leaders for our custom power management and protection solutions, which help simplify our customers’ production processes.”
To meet current carry and temperature requirements, Sensata’s cooling and temperature control technology directly interfaces to the busbars and provides exceptional cooling efficiency within tight space restraints. For additional safety, Sensata’s isolation monitoring design ensures isolation of the high voltage from the chassis. The solutions’ software and controllers are built on the AUTOSAR platform.
