Addressing "Range Anxiety" in Electric Vehicles
Learn how STMicroelectronics solves some of the toughest design challenges associated with electric vehicle charging and battery management
The battery pack is among the most expensive components found in battery-operated products such as power tools, scooters, and electric vehicles (EV). In electric vehicles, battery pack performance greatly influences vehicle-level concerns including vehicle range, battery pack service life, and charge time, not to mention vehicle safety and reliability.
Therefore, it is not surprising that battery management is the subject of intense research and ongoing development effort. A key element of battery management is battery charging, which includes a growing infrastructure of Electric Vehicle Service Equipment (EVSE), as well as the On-Board Charger (OBC) that is part of the vehicle electrical system. This session will cover the energy conversion aspects of EV charging with emphasis on power electronics architecture, and how to implement charging and energy storage strategies that increase battery performance and thus help to relieve "range anxiety".
You will learn:
- The factors that contribute to EV "range anxiety", and how to mitigate them
- About different EV charger architectures and their use cases
- The pros and cons of Lithium-Ion batteries for EV energy storage
- Battery management architectures that maximize battery efficiency and longevity
