Small gas gauging devices have found their way into many consumer, industrial, and medical applications. In a previous blog post , we introduced our bq274xx series of Li-Ion gas gauges. In this video, we introduce the bq27xx series of gas gauges. The biggest…
Other Parts Discussed in Post: BQ27426 You might have heard of phrases like “gauge made easy,” “easy-to-use gauge,” “value-gauge products” or even “gauge in a few clicks.” The truth is that there is no easy way to make a “good” battery fuel gauge, but…

Once you realize that you need to at least give your user some basic indication of your Li-Ion battery’s state-of-charge, you might also realize other features and benefits that a fuel gauge can offer. Let’s…
Even if you don’t need the highest accuracy from your lithium-ion (Li-ion) battery gauge, some insights into the electrochemical process inside the cells will help you understand the suitability and limits of various approaches to gauging.
Gauging…
Other Parts Discussed in Post: BQSTUDIO Previously, I wrote about why your battery-powered product needs a fuel gauge. If you identified with this need, then you might have looked around to see what gauges are available and thought about dropping one into…
Since it’s commercialization by Sony in 1991, lithium-ion (Li-ion) batteries have been widely adopted in portable devices for consumer, industrial and medical markets. The Li-ion battery is now making its way into many more sectors, replacing existing…
I always get excited to hear about a cool new portable design that uses TI chips inside – but then sometimes get equally flustered when I find out there’s no battery fuel gauge in the product.
You see, I'm part of the large team at TI…
David Maxwell, battery management systems engineer at TI, developed the following technical design tutorial on battery fuel gauging for single-cell Li-Ion batteries. In Part 1 of his Fuel Gauging 101 course, David discusses the fundamentals of lithium…
전 세계에서 여느 때보다 배터리 구동이 늘면서 우수하고 저렴한 배터리와 배터리 팩에 대한 수요가 급증하고 있다 . 배터리 제조업체들이 새로운 화학 물질과 더 작은 팩을 도입하고는 있지만 ( 그에 따라 전력 요구 사항에 새롭고 더 복잡한 제약이 따르고 있지만 ) 근본적인 기능은 동일하다 . 오늘날의 배터리는 시스템 성능의 저하 없이 사용 시간과 유통 기한이 최대한 길어야 한다 .
낮은 대기 전력, 빠른 응답 시간, 소형 폼 팩터
TI 저 I Q 기술의 이점에 …
