Mare @ e.pavlin.si designed a single cell Li-Ion battery pack simulator to facilitate the testing process of a new device. Modern battery operated portable devices use smart battery packs. Every new development of an electronic medical device must follow strict design flow defined by world-wide or local regulatory directives. The development process of any such […]

Newly Developed Internal Temperature Sensor For Li-ion Battery Enables 5x Faster Charging


https://www.electronics-lab.com/newly-developed-internal-temperature-sensor-lithium-battery-enables-5x-faster-charging/

Researchers at the University of Warwick in the UK have developed sensors which measure the internal temperature and electrode potential of Lithium batteries. The technology is being developed by the Warwick Manufacturing Group (WMG) as a part of a battery’s normal operation. More intense testings have been done on standard commercially available automotive battery cells. […]

JuiceBox Zero: Easiest way to power a Pi Zero with a battery

You have a Raspberry Pi project, but it’s no good stuck to a wall! JuiceBox Zero is the simplest way to properly power your Pi Zero. by Samuel Anderson @ kickstarter.com: I had an amazing project for Raspberry Pi that needed to be battery powered. I searched and found a few boards that served the […]

Could Sodium-ion Batteries be a Replacement for Li-ion Batteries?


https://www.electronics-lab.com/sodium-ion-batteries-replacement-li-ion-batteries/

In early 1990s lithium-ion batteries started gaining popularity as a substitute for nickel-cadmium batteries. They have higher energy density, low self- discharge, and low maintenance, but it was soon found that they have short life span, unstability which causes security concerns and creates the need for protection circuits (to maintain it within safe limits), and […]

Flexipower – A portable, Controllable, Dual Channel Power Supply


https://www.electronics-lab.com/flexipower-portable-controllable-dual-channel-power-supply/

Hobbyists, makers, students and pretty much everyone who works with electronics has encountered the same issue, not having a handy power supply to test their projects. Usually, controllable power supplies are big, expensive and for some people difficult to access, and most small power supplies are not controllable. As a result, Roberto Lo Giacco created […]

Rechargeable Magnesium Batteries – Safer And Cheaper Than Li-ion Batteries


https://www.electronics-lab.com/rechargeable-magnesium-batteries-safer-cheaper-li-ion-batteries/

Researchers at the University of Houston reported in the journal Nature Communications the discovery of a new design that significantly improves the development of a battery based on magnesium. Magnesium batteries are considered as safe resources of power supply – unlike traditional lithium-ion batteries. They are not flammable or subject to exploding – but their ability to store energy is […]

Integrated 36V buck battery charger provides seamless backup power


https://www.electronics-lab.com/integrated-36v-buck-battery-charger-provides-seamless-backup-power/

By Graham Prophet @ eedesignnewseurope.com: LTC4091 is a complete lithium-ion battery backup management system for 3.45V to 4.45V supply rails that must be kept active during a long duration main power failure. The LTC4091 employs a 36V monolithic buck converter with adaptive output control to provide power to a system load and enable high efficiency […]

Fuel gauge needs no battery characterization


https://www.electronics-lab.com/fuel-gauge-needs-no-battery-characterization/

by Susan Nordyk @ edn.com The MAX17055 single-cell fuel gauge from Maxim not only eliminates battery characterization, but also keeps SOC (state-of-charge) error to within 1% in most scenarios. With its ModelGauge m5 EZ algorithm, the device provides tolerance against battery diversity for most lithium batteries and applications. It also allows system designer’s to decide […]
