Watch the 1-hour webinar recording to learn about the auto industry’s trend toward vehicle electrification, the key role battery management plays in electric vehicle (EV) performance, and how STMicroelectronics is responding to both.

In the transportation industry, greenhouse gas emissions and the net environmental impact of burning fossil fuels has historically been the Achilles heel for manufacturers of motor vehicles and other energy conversion products.

As a result, several large automotive OEMs have abandoned product development efforts involving traditional powertrain systems, and ICE (internal combustion engine) programs in particular. These frontrunners are putting years of research into practice, electing to move toward vehicle “electrification” at a fever pitch. Of particular importance in EV performance is battery management. The care and feeding of the battery pack has become an area of intense research and development, and STMicroelectronics is developing new solutions to meet this challenge.

During the session, we will explore some historical perspectives and the underlying physics of electric vehicle performance, with a focus on battery management. We will introduce a few central concepts, system requirements, and design challenges, along with some solutions suitable not only for transportation, but for other battery-powered applications as well.

You will learn:

  • Historical and market perspectives of EV performance
  • Applicability of transportation solutions to other markets
  • Electric vehicles: a system approach
  • Fossil fuels vs. electricity
  • Charging infrastructure
  • Battery management (Li-ion)
