Batteries and Energy Storage

Kevin Parmenter, Director, Applications Engineering. TSC, America

Batteries are a hot topic. Prior to the pandemic, I counted about 355 battery-centric events being held worldwide over a year-long period – almost one a day. This comes as no surprise since the global battery market was valued at USD 108.4 billion in 2019 and is expected to have a compound annual growth ra

Next-Generation Battery Management System Architectures

Next-Generation Battery Management System Architectures

Konrad Lorentz, Product Manager Battery Management Systems and Emiliano Mediavilla Pons, Automotive Principal Functional Safety Architect (BMS) at NXP Semiconductors

DC fast chargers take between 30 to 45 minutes to charge the battery to 80 percent. This fast charging process generates a significant amount of heat, because the internal resistance to the high current generates a temperature rise. For a typical 400 V EV battery, therefore, the charging rate is limited by se

Application of Power MOSFET in Battery Management Charge-Discharge System

Song Liu, Sr. Applications Engineer, Discrete Products, Alpha and Omega Semiconductor, Inc., and Neil Zhang, Applications Engineer, Discrete Products, Alpha and Omega Semiconductor, Inc.

Power MOSFETs are required to be connected in series between the inside of the lithium-ion battery pack and the output load. At the same time, the dedicated IC is used to control the on and off of MOSFET for managing the charge and discharge of the battery, as shown in Figure 1. In consumer electronic systems, su

It’s beginning to look a lot like…normalcy. And for someone who gets cabin fever when I’m stuck inside for even a day, I couldn’t be happier. New COVID-19 cases continue to drop, from a U.S. 7-day average of nearly 700K as of 1/24 to 85K as of 6/21. Obviously, tens of thousands of instances of some
