Wireless Communication in Automotive BMS

Tomas Urban – Systems Engineer in Automotive, Texas Instruments

Batteries in EV/HEV reach nominal voltages of 400 V or 800 V. The batteries are typically organized in modules that are managed by a dedicated battery management integrated circuit (BMIC). Typically, one BMIC can monitor up to 16 cells connected in series. The main role of the BMIC is to periodically measure th

Getting Electric at the Close of the Summer

Jason Lomberg, North American Editor, PSD

Welcome to the August issue! Summer’s nearly over, and here’s hoping you were able to holiday somewhere fun, possibly by availing yourself of our topic this month (EVs, Hybrids, and Charging Infrastructure). My personal vehicle is a hybrid, though I haven’t ruled out graduating to an electric vehicle,
