Every car needs a battery to help it start and power its electronics. Here's how many volts this all-important component ...

What's the difference between amperes and watts, and what does voltage have to do with them? Here's how you can tell which ...

Traditional ICE (internal combustion engine) cars keep the 12-volt battery topped up with an alternator. When the gas engine is running, a belt turns the alternator, which generates DC power to ...

Battery-operated equipment often requires a low-voltage monitor to warn the user when the battery voltage is too low or to perform other functions, such as power-source switching or device shutdown.

Battery cell voltage is the most fundamental measurement made on the cell. While on the surface measuring voltage seems easy, challenges and accuracy considerations must be understood before your cell ...

U.S. scientists used density functional theory to reveal how sodium ions are stored in nanoporous carbon anodes for sodium-ion batteries, identifying dual ionic and metallic storage mechanisms within ...
