Long-life batteries harness the passivation effect
A little known chemical reaction helps extend battery life. Sol Jacobs, Tadiran Batteries As remote wireless devices become increasingly essential to the Industrial Internet of Things (IIoT), there is a growing need to understand the principles behind extended battery life. Many IIoT nodes require a battery-driven energy source. These off-grid low-power applications fall into two […]
Plastic battery holders have optional built-in on/off switch
The widely used Densi-Pak covered plastic battery holders now include the option to have a built-in On/Off switch. The built-in On/Off switch eliminates the need for additional components in designs using “AA” and “AAA” batteries – a candidate for self-contained powering components in a variety of applications. These high-performance Battery Holders are made with an […]
Battery Management Systems: Effective ways to measure state-of-charge and state-of-health
By Andrey Solovev, Chief Technology Officer, Integra Sources One of the purposes of battery management systems is to monitor the state-of-charge and state-of-health of rechargeable batteries. This article will tell you about these two metrics and the methods used to measure them. Rechargeable batteries are used in many solutions, but industries use battery management systems […]
Up in the sky! It’s a bird! It’s a plane! It’s a flying battery!
leland teschler, Executive editor According to a company called Joby Aviation, in a few years you’ll be able to summon up an air taxi on your Uber phone app for trips of 25 miles or so. And you won’t have to feel guilty about the environmental impact of your trip because the plane will actually […]
Thionyl Chloride batteries excel in asset tracking, high-power apps
Ultralife Corporation has extended its ER Generation X family of Lithium Thionyl Chloride (LiSOCl2) batteries for critical applications, with two new products added to the range of rugged, energy-dense batteries. The new additions are the low rate UHE-ER14250-X 1/2AA size bobbin cell for asset tracking and more, plus the high-rate UHR-ER18505-X A size spiral cell for […]
Modules help add wireless charging to small devices
Rohm Semiconductor announced they have developed compact wireless charger modules with an integrated antenna board: the BP3621 (transmitter) and the BP3622 (receiver). These new modules allow designers to add wireless power supply functionality to smaller devices such as smart tags/cards or PC peripherals. Wireless power supplies are increasingly being adopted in smartphones, smart watches, and other compact devices. […]
Low-voltage MOSFETs feature low Rss(on) for smartphone battery PCMs
Magnachip Semiconductor Corporation announced the launch of a new generation Low-Voltage Metal Oxide Semiconductor Field Effect Transistors (LV MOSFETs) featuring lower Rss(on) for battery Protection Circuit Modules (PCMs) in smartphones. As demand for high-end 5G and LTE smartphones increases, extended battery life and strengthened protection features for batteries are becoming important. 5G phones, in particular, need long-lasting […]
Voltage rail splitters and virtual grounds for batteries and PFCs
Rail splitters are usually associated with battery-powered devices, but that’s not always the case. There are several definitions of a “rail splitter,” sometimes referred to as a “virtual ground” or “pseudo ground.” The most common meaning is creating a new “0V” reference point, usually the mid-point Vin/2 of a single supply voltage such as a […]
Don’t rush to choose rechargeable batteries…at least, not yet
Using energy harvesting and a rechargeable battery to power a remote wireless IoT node seems like an obvious and straightforward solution, but there are some unique aspects to consider. Don’t get me wrong: I really like rechargeable batteries; in fact, I like them a lot. Whether based on lead-acid, nickel-cadmium, lithium-ion, or other chemistry, our […]
