Major Vehicle Manufacturer EDU System Strategy

eAxle powertrain ‘design space’ technology selection, ‘trade-off’ study and optimisation.

Project Objective

• Determine long term eAxle strategy based on 3 in 1 efficiency vs production cost directional analysis covering large range of sub-system technologies.

Outcome and Customer Benefits

• Strategy developed providing OEM with fundamental eAxle strategy and reference, considering multiple transmission types and a matrix of 24 motor technologies / topologies ePOP output database provided allowing further detailed production cost ‘what-if’ modelling.
• Strong correlation of energy simulations from ePOP and OEM more detailed (and slower) toolset.
• Good correlation of the ePOP directional cost models with the OEM high volume production cost predictions.

Timeline

• Setting up all 3 in 1 sub-systems and simulation – 8 weeks.
• Analysing, and reporting of what-if analyses and preferred eAxle architectures – 6 weeks.
