Over the last couple of decades the use of rechargeable batteries has grown enormously, and for most common applications there are ASICs[1] which control battery management with very little additional ...

The circuit was designed to create a spare and reserve power source with the use of batteries during the absence of power from the mains. BD139 – NPN power transistor used for driver stages in hi-fi ...

Testing a Li-ion battery charger using its natural load (i.e., a battery) is time consuming because the charging process can take an hour or more. The test time varies widely, depending on whether you ...

Because stationary batteries and 48VDC power systems serve as lifelines for telecommunication networks, the reliability of these systems is of the utmost importance. Many system designers rely on ...

LONDON--(BUSINESS WIRE)--According to the latest market study released by Technavio, the global battery management integrated circuit (IC) market is projected to grow to USD 8.78 billion by 2021, at a ...

I will be talking about single-series (1sXp) cell configurations, for a simple reason – multiple-series configurations are not something I consider myself as having worked extensively with. The single ...

In this video I’m showing how I’ve built a very simple battery backup circuit for my home alarm system. The circuit charges a 12v lead acid battery and in an event of a power loss, it transfers the ...

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

The bulky batteries that power mobile devices could one day be extinct. Oki Printed Circuits has showcased technology that embeds a 170?m-thick thin-film all-solid-state lithium-ion (Li-ion) ...

For the first time, scientists have observed how tiny metal "thorns" called dendrites sprout inside lithium-ion batteries, which can cause the batteries to short-circuit. Their findings, published in ...

Researchers have uncovered the mechanical properties of the nanoscale "thorns" that develop inside lithium-ion batteries, which can cause them to short circuit and die – or worse, such as ...
