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 ...

A battery that "talks" does not use words—it communicates through data. Researchers at Kiel University have demonstrated how ...

A compact electronic circuit enables battery cells to transmit temperature data through charging and discharging terminals ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...

Solving the design challenge to efficiently deliver higher battery charge current in small portable applications, Texas Instruments Incorporated (TI) (NYSE: TXN) announced the first synchronous, ...

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 ...

How lithium-ion (Li-ion) batteries behave under short-circuit conditions can now be examined using a new approach developed by a UCL-led team to help improve reliability and safety. The use of high ...
