An automobile auxiliary power outlet (also known as car cigarette lighter or auxiliary power outlet[ 1]) in an automobile was initially designed to power an electrically heated cigarette lighter, [ 1] but became a de facto standard DC connector to supply electrical power for portable accessories used in or near an automobile directly from the ...
An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle. Once the engine is running, power for the car ...
Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]
A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [ 1][ 2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when charging is complete—depends on the size and type of the ...
Universal charger. Universal charger or common charger refers to various projects to standardize the connectors of power supplies, particularly for battery-powered devices. Since the publication of the USB Power Delivery standard in 2012, and the USB-C connector in 2014, USB-C has become a widespread standard for charging mobile phones.
A battery regenerator is a device that restores capacity to lead-acid batteries, extending their effective lifespan. They are also known as desulphators, reconditioners or pulse conditioning devices. [ 1] When batteries are stored in an uncharged state for an extended period, lead-sulfur deposits form and harden on the lead plates inside the ...
Self-discharge is a chemical reaction, just as closed-circuit discharge is, and tends to occur more quickly at higher temperatures. Storing batteries at lower temperatures thus reduces the rate of self-discharge and preserves the initial energy stored in the battery. Self-discharge is also thought to be reduced as a passivation layer develops ...
Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. [ 1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing. [ 2]
