Larger and More Reliable Batteries and the Means to Charge Them

Jason Lomberg, North American Editor, PSD

Welcome to the July issue! We’ve just passed the official start of summer in the Northern Hemisphere (sorry, Antarctica!), and with kids home from school and the weather considerably less treacherous, we hope you’re able to enjoy the outdoors, and pull yourself away from the workbench long enough for an ho

A Summer Recharge

Ally Winning, European Editor, PSD

Welcome to the July edition of Power Systems Design Europe. Summer is generally the quietest time for the industry before the busy autumn season. It gives us the chance to relax and recharge ourselves and also some time to reflect on the beginning of the year. Within a comparatively short period of time, things a

BMS Transformers in Energy Storage Systems

Samuel Lamprecht and Gerhard Stelzer, Würth Elektronik

The conversion of electric grids to renewable energies, especially wind power and photovoltaics, which are not always available, is fueling the need for larger energy storage systems. These require a sophisticated battery management system (BMS) for reliable operation. BMS transformers can be used to insulate th

Why Accurate Cell Data Matters in Battery SoC and SoH Determination

Gavin McVeigh – Senior Director System Architecture at Dukosi

As SoC and SoH cannot be directly measured, various methods of computational complexity are used to determine their values. The accuracy of quantifiable metrics—temperature, voltage, and current—and the synchronization of data captured for all cells are critical inputs for the algorithms used to determine ov

PassThru of a Voltage Using Buck-Boost Regulators

: Frederik Dostal, Field Applications Engineer, Analog Devices

This article will illustrate how special converters equipped with PassThru™ mode can be useful when the circuit’s input voltage is too high or too low to power a load. It will give examples of how PassThru mode is used with buck-boost regulators and boost regulators to increase power supply efficiency an
