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 , amperes, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
the fraction of the battery's capacity which is currently removed from the battery with regard to its (fully) charged state. For fully charged batteries, the depth of discharge is connected to the state of charge by the simple formula D o D = 1 − S o C {\displaystyle \mathrm {DoD} =1-\mathrm {SoC} } .
In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready.

1,800–5,000 (NiMH) 1.2: 22.2 × 42.9 (0.87 × 1.69) A common size for cells inside cordless tool battery packs. This size is also used in radio-controlled scale vehicle battery packs and some Soviet multimeters. 1 ⁄ 2-, 4 ⁄ 5 - and 5 ⁄ 4-sub-C sizes (differing in length) are also available. Soviet 332 type can be replaced with R10 (#4 ...
A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries to protect against electrical overload, overcharging, and may protect against overvoltage. [1] [2] This prevents conditions that reduce battery performance or lifespan and may pose a safety risk. It ...
Most manufacturers claim that overcharging is safe at very low currents, below 0.1 C (C/10) (where C is the current equivalent to the capacity of the battery divided by one hour). [23] The Panasonic NiMH charging manual warns that overcharging for long enough can damage a battery and suggests limiting the total charging time to 10–20 hours. [22]
