Global commercial vehicle manufacturer selects Eaton's new 48V aftertreatment heater controller to meet upcoming emissions regulations
16 October 2023
Eaton, the intelligent power management company, today announced it has entered into its first agreement to provide a global commercial vehicle manufacturer with powertrain solutions for electric powertrains. New 48V programmable aftertreatment heater controller for heating catalyst . Rapidly heating the diesel aftertreatment catalyst and maintaining its temperature when the engine is operating at low loads is critical to achieving optimal performance to reduce harmful nitrogen oxide (NOx) exhaust emissions.
Ben Karrer, director of low voltage and power conversion engineering for Eaton's Vehicles and Vehicle Electrification Group, said: "Eaton was selected as the supplier of this system because of its long history in the development of low voltage power conversion and power electronics solutions. Over the decades, we have We have been selling similar technology to sectors such as agriculture and military applications around the world. Now we are bringing this innovative technology to the commercial vehicle sector, which is a milestone for us.”
The air-cooled electrocatalyst heater controller is part of Eaton's broader 48V electrical systems portfolio. The product portfolio includes multiple technologies that enable manufacturers to integrate 48V architecture in next-generation vehicles. Eaton's range of electric heater power electronic controllers have been developed for solutions with powers between 2kW and 15kW, with peak efficiencies of up to 99%. The controller is designed to receive power commands from the aftertreatment system, provide soft start and stop functions to assist in maintaining system voltage control, and provide diagnostic feedback to the heater element.
“The aftertreatment catalyst heater controller contains all the necessary power electronics to efficiently power the heater, thereby optimizing engine performance and ensuring that the vehicle electrical system remains stable during heater operation,” said Karrer.
The technology comes as carmakers face tightening global emissions standards. In the United States, the California Air Resources Board and the U.S. Environmental Protection Agency will enact stricter diesel regulations in 2024 and 2027. In Europe, the next stage of emission standards is called the "Euro VII" emission standards for heavy-duty diesel trucks. Overall, the new regulations aim to reduce tailpipe NOx emissions by up to 90%, accelerating the need for manufacturers worldwide to adopt additional emission reduction strategies such as electrocatalyst heating.
Eaton is an intelligent power management company dedicated to improving the quality of human life and enhancing the quality of the environment. Now and in the future, we are committed to operating with integrity, growing sustainably and helping our customers better manage power. With the help of electrification and digitalization trends, we are accelerating the global transition to renewable energy, helping to solve the most pressing power management challenges and creating more value for our stakeholders and society.
