Leading electrification solutions provider for clean commercial vehicle transportation, Dana, announced an expansion of its Spicer Electrified e-Powertrain offerings to include a family of e-Transmissions for a wide variety of medium-duty electric-vehicle applications. The technology will launch on a global electric vehicle platform in early 2024.
The transmissions optimise operating range and vehicle performance for applications suited to a central drive e-Propulsion system with a conventional axle and driveshaft layout.
According to a communication from the company, its engineering team brings the market an integrated system, leveraging in-house capability for motors, inverters, gearing, clutches, thermal management, and software solutions. The new e-Transmissions have been engineered to provide improved efficiency and performance with maximum startability, gradeability, and road speed.
Other key features include a high-efficiency motor and integrated inverter system, with silicon carbide technology and MOSFET power modules, providing peak performance and simplified installation in the vehicle through the elimination of high-voltage phase cables. An electromechanical actuation system, with its patented Graziano clutch design, maximises shift smoothness and efficiency. An optimised three-speed system with Ravigneaux gearing designed to seamlessly integrate the motor technology, offer maximum power density and productivity without compromise across a wide range of vehicles.
In addition, the company's OpenECU platform, leveraged across all e-Propulsion technologies, delivers next-generation control software, functional safety readiness up to ASIL C, and compliance with the latest vehicle cybersecurity engineering standard ISO/SAE 21434 and the UNR 155/156 regulations.
