To calculate the discharge rates of EV batteries, we first need to understand how lithium-ion batteries work and how they are used. Nearly all electric vehicles on the market today feature a ...

Sometimes, your battery loses its power without you knowing. In some cases, people put their gadgets inside safe storage only to discover later that their 100% battery is not full anymore.

When selecting cells for a power battery, it is useful to have the ability to quickly compare various cell technologies, and calculate the resulting pack resistance and efficiency, independently of ...

Scientists from University of California, Irvine have developed a nanowire-based battery material that allows off-the-charts charging, which may eventually make battery replacement obsolete. The ...

This circuit prevents over-discharge of a lead-acid battery by opening a relay contact when the voltage drops to a predetermined voltage (lower voltage threshold). When the battery is recharged to a ...

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 ...
