Summary of eMobility eBook

Introduction

This eBook provides a comprehensive guide to developing efficient power delivery networks for eMobility (such as EVs, eVTOLs, and autonomous vehicles). It emphasizes overcoming challenges like compact size, high efficiency, and thermal management by leveraging Vicor's high-density power modules. These modules enhance performance, reliability, and time-to-market for eMobility products.

Benefits of Vicor Power Modules

• High Power Density: Enables kilowatts of power in a small footprint, optimizing space in vehicles.
• High Efficiency: Achieves 96-98% peak efficiency, reducing heat dissipation and improving overall system performance.
• Fast Transient Response: Quickly adapts to load changes, essential for dynamic conditions like acceleration and braking.
• Low EMI: Minimizes electromagnetic interference, simplifying filtering and ensuring stable operation.
• Modular and Scalable Design: Allows easy paralleling and swapping of modules to accommodate various power needs without redesign, providing flexibility and redundancy.

Case Studies

• Lightning Motorcycles Electric Bikes: Utilizes Vicor modules to extend range, reduce charge times, and handle diverse battery chemistries in compact designs.
