In June, 2021, it was announced that Ideanomics Inc. had completed acquisition of privately-held US Hybrid, a manufacturer and distributor of electric powertrain components and fuel cell engines for medium and heavy-duty commercial fleet applications. The completed acquisition wasreported as a critical milestone in Ideanomics' mission to reduce commercial fleet greenhouse gas emissions through advanced EV technologies and forward-thinking partnerships - an effort that has recently involved acquisition of other SBIR-involved firms.

The company's technical services and products are targeted for original equipment manufacture (OEM) applications. The firm offers comprehensive engineering expertise and experience in electric and Hybrid vehicle systems and components, including Integrated Motor Drive, dc-dc power conversions and high-performance AC motors and controllers. US Hybrid's products utilize integrated Digital Signal Processor power converter topologies to provide reliable and cost effective integrated system solutions.
