New Tech Tuesdays

Join Rudy Ramos for a weekly look at all things interesting, new, and noteworthy for design engineers.

The need for efficient energy storage and management has become increasingly important in today's rapidly evolving technological landscape. This need is particularly critical in applications such as residential battery storage systems, high-voltage battery stacks, and battery backup systems. This week's New Tech Tuesday looks at the importance of battery management systems and how the ADES175x series data-acquisition systems from Analog Devices offers cutting-edge solutions designed to optimize the performance and reliability of these systems.

Residential Battery Storage Systems

With the increasing adoption of renewable energy sources, residential battery storage systems play a crucial role in ensuring energy availability and reducing dependency on the grid. Efficient management of these systems requires precise monitoring and control of battery modules.

High-Voltage Battery Stacks

High-voltage battery stacks are fundamental in various industrial applications, including electric vehicles (EVs) and large-scale energy storage systems. These applications demand robust and reliable data-acquisition systems to effectively manage the complex requirements of high-voltage operations.

Uninterruptible Power Supplies

Uninterruptible power supplies (UPS) are critical in maintaining continuous power delivery during outages. The ADES175x series provides the necessary tools to ensure that battery backup systems can respond swiftly and efficiently, maintaining power integrity and system reliability.
