Tau Motors Wins "Vehicle-To-Everything (V2X) Innovation Of The Year" In 2023 Autotech Breakthrough Awards Program

Annual Awards Program Recognizes Innovation in Automotive and Transportation Technologies Around the GlobeLOS ANGELES, Oct. 12, 2023 (GLOBE NEWSWIRE) -- AutoTech Breakthrough , a leading market intelligence organization that recognizes the top companies, technologies and products in the global automotive and transportation technology markets announced that Tau Motors , an advanced technology company that develops next-generation products for electrification, wins this years’ “Vehicle-to-Everything (V2X) Innovation of the Year” award in the fourth annual AutoTech Breakthrough Awards for its software-defined power converter system.Tau's Ion converter system is made up of next next-generation power electronics modules – called auto converter modules (ACMs) – that can be configured together like building blocks and resolve all power conversion challenges locally at the device level. Smart power conversion is critical to advance the world today. Fundamentally, electrification requires the need for power in different forms – whether alternating current (AC), direct current (DC), or different voltage or current levels. Tau’s Ion modules shrink the cost, size, and components required for power conversion which enables industry leading efficiencies, scalability, and power densities (processing more power per unit volume). Notably, the power density of Tau’s soft-switching Ion modules has continued to double approximately every two years while achieving particularly high efficiency – in excess of 99%.Tau’s Ion system includes adaptive smart filtering technology and advanced controls to enhance the reliability of power conversion systems – while also providing a software-defined, networked system that offers redundancy and reconfiguration through a hierarchical protocol that enables smart energy conversion
