White Paper Overview

The use of battery-powered energy storage and portable equipment has grown steadily. The demand for more power, along with longer range or run time, dictates an increase in the voltages used in their battery stacks. Applications in industrial systems using a 24 VDC power supply can see 60 V peak voltage during transient conditions. Legacy charger solutions are mostly limited to 28 V input. Read this white paper to learn how newer charger solutions from Analog Devices enable higher battery stack voltage and higher charging efficiency, thanks to the high voltage, synchronous buck charging topology.

Lead-acid batteries, lithium-based batteries, and supercapacitors are all energy storage devices that have very distinct charging/discharging characteristics and require a dedicated charger for an optimum charging solution. An advanced battery charger also provides adequate protection to give battery performance and durability, especially when charging under adverse conditions. These are also addressed in newer charger solutions.
