Lightweight 2 Speed Electric Drive Unit

Commercial Vehicle (CV) application demonstrating optimised performance over a single speed and supporting the customer product strategy to move into the electrified driveline sector.

Project Objective

• Demonstrate a lightweight efficient mid-size truck eAxle for a Tier 1 creating a new eAxle capability.

DSD Responsibilities

• Define targets and requirements.
• ePOP Architecture Optimisation to meet fleet cycle targets.
• Integrate and system engineer the selected eAxle 2 speed concept to demonstrate the technology, including the electro-mechanics and the control system using AMT modules from DSD ‘Infinite Control’ software.

Outcome and Customer Benefits

• Evaluation of motor, inverter and transmission technologies for establishing the most suitable electrification strategy for the truck.
• eAxle A-sample DVP testing completed, with technology proven and transferred, supporting the Tier 1 strategy to become an eAxle supplier.

Timeline

• ePOP based eAxle architecture definition – 8 weeks.
• A sample eAxle detail design and release – 20 weeks.
• A sample manufacturing, test – 35 weeks.
