Self-discharge is a chemical reaction, just as closed-circuit discharge is, and tends to occur more quickly at higher temperatures.

Self-discharge is also thought to be reduced as a passivation layer develops ...
Here’s how you can do the same — and not just for your car. Buy to keep. When Veitch bought her car, she knew she wanted the $3,289 vehicle to last forever. She learned all the mechanical ...

Inductive charging is also used in ...
Trickle charging. Trickle charging means charging a fully charged battery at a rate equal to its self-discharge rate, thus enabling the battery to remain at its fully charged level; this state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.
A British startup may have found the answer to one of the frustrations of driving an electric car — waiting around for the battery to charge. This electric car battery takes less than 5 minutes ...
Tens of thousands of AT&T customers in America could not make phone calls, send texts, reach emergency services or access the internet. At the time, the mobile network issued a $5 credit to ...
When the phone is set on the pad, a coil in the pad creates a magnetic field [1] which induces a current in another coil, in the phone, charging its battery. Wireless power transfer ( WPT ), wireless power transmission, wireless energy transmission ( WET ), or electromagnetic power transfer is the transmission of electrical energy without wires ...
