Tier 1 Customer started their electrification journey with a powertrain concept intending to support a modular platform for their heavy duty commercial battery electric drivetrain solution.
Having completed a holistic platform study to span all customer applications and duty cycles, Romax delivered a highly integrated multispeed transmission, traction motor and electro-hydraulic shift actuation system, with Power Electronics and Transmission Control Unit hardware and application software, prepared with an ASIL-C ISO26262 compliant safety case in anticipation for a fleet trial.
Romax supplied the integrated hardware and managed the system integration and physical verification testing, delivering a right-first-time solution proven via our virtual verification capability. Our solution delivered >10% range increase over the drive cycle, at a 1/3 less mass, 1/3 less volume and a 1/3 of the cost of the preceding powertrain concept.
