2. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   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 and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

3. List of battery sizes - Wikipedia

   en.wikipedia.org/wiki/List_of_battery_sizes

   W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies. Multiple B batteries may be connected in series to provide voltages as high as 300 V DC. Some versions have a tap at 22.5 volts. GB Battery: C Battery Eveready 761: 1.5 to 9 V: Threa­ded posts or banana sockets H: 76.2 ...

4. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet. The voltage of the source must be higher than that of the battery to force current to flow into it, but not too much higher or the battery may be damaged.

5. AC adapter - Wikipedia

   en.wikipedia.org/wiki/AC_adapter

   An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.

6. Derating - Wikipedia

   en.wikipedia.org/wiki/Derating

   Power semiconductor devices have a maximum power dissipation rating usually quoted at a case temperature of 25 °C (77 °F). The datasheet for the device also includes a derating curve which indicates how much a device will dissipate without getting damaged at any given case temperature, and this must be taken into account while designing a system.

7. Battery management system - Wikipedia

   en.wikipedia.org/wiki/Battery_management_system

   A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...

8. Charging station - Wikipedia

   en.wikipedia.org/wiki/Charging_station

   Case A: any charger connected to the mains (the mains supply cable is usually attached to the charger) usually associated with modes 1 or 2. Case B: an on-board vehicle charger with a mains supply cable that can be detached from both the supply and the vehicle – usually mode 3. Case C: DC dedicated charging station. The mains supply cable may ...

9. Inductive charging - Wikipedia

   en.wikipedia.org/wiki/Inductive_charging

   Inductive chargers produce more waste heat than wired chargers, which may negatively impact battery longevity. [ 14 ] [ better source needed ] An amateur 2020 analysis of energy use conducted with a Pixel 4 found that a wired charge from 0 to 100 percent consumed 14.26 Wh ( watt-hours ), while a wireless charging stand used 19.8 Wh, an increase ...
