• What are the challenges to balance efficiency and costs when designing an eAxle?
• What advancements in materials science are contributing the most to enhance the performance and cost-effectiveness of eAxles?
• Which technologies could revolutionize the design and characteristics of eAxles?
• How to evaluate and validate accurately the performance metrics of eAxles, and how to consider real-world driving conditions?
• What are the KPIs we should focus on when evaluating design effectiveness, and how to accurately measure them?
• What are there alternative solutions to current standard eAxle solutions (multispeed transmission or hub-motor), and how do they influence the motor requirements? 

This presentation begins with a brief overview of Bosch Mobility’s current portfolio. Following this introduction, a reference system is presented, which will serve as the basis for various thermal analyses, including comparing the influence of the cooling system, evaluating the impact of machine design, and assessing the effect on drive cycle efficiency. Finally, a concise summary of the study is provided, along with a discussion on eAxle efficiency and future trends.

 This presentation will provide insights into:

• The Bosch Portfolio
