Bringing Intelligence to Battery Management for Industrial Applications

Posted on 07 October 2013

      Lithium-Ion (Li-Ion) battery technology first emerged in the early 1990s as the preferred high-performance solution for portable computing applications. By the end of the 1990s, it had become the battery of choice for mobile phones as well. By Upal Sengupta, Staff Applications Engineer and Rajakrishnan Radjassamy, Business Development Manager, Battery Management Solutions, [...]

Posted on 07 October 2013

      Medical Sensors and Instruments By Steve Grady, Cymbet New Solutions for Powering Medical Devices Small medical sensors and surgical instruments are rapidly becoming intelligent and therefore they must be powered - often using miniature rechargeable batteries. Integrated batteries must have several key properties in order to insure safe operation and protect patient [...]

Understanding System Loads and Interfacing with Chargers

Posted on 01 March 2009

      System power must not exceed charger power without energy storage Battery charging is a fairly simple concept when considering only a standalone charger for a given input voltage, charge level and pack size. However, charging is often done with a system load, which can complicate charging. This article highlights the potential startup [...]

      New and Emerging Trends The new and emerging generation of handheld devices such as cellular phones, portable media and navigation equipment, Bluetooth headsets continue to shrink in size and form factor while improving performance and features. When it comes to charge management, these improvements force the design engineer to strike a balance [...]

Watching Out for You

Posted on 01 December 2008

      Continuous monitoring is important in backup battery applications We increasingly rely on technology to provide us with a feeling of security; cameras, emergency telephones and even safety lighting have a reassuringly high profile, letting us know that, if they are ever needed, they’re available. Ensuring their availability in times of emergency can [...]

A Balanced Approach to Battery-Charging

Posted on 01 September 2008

      Correctly balancing delivers improved battery performance Charge-balancing for series-connected battery cells means balancing the trade-offs across a number of techniques. Whilst battery cells connected in parallel tend to be self-balancing, cells connected in series will typically need to be balanced to prevent over-charging which can lead to over-heating, increased pressure and reduced [...]

Maximizing Integrated Battery Charger Performance

Posted on 01 March 2007

      Intelligent thermal control managing power New multi-function power management ICs promise to reduce PCB size by integrating multiple blocks onto a single chip. Such integration can threaten system integrity by exceeding the thermal limits of the device package. An intelligent thermal control circuit eliminates this problem by dynamically managing power usage and, [...]
