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.
GM Ovonic NiMH Battery Module. NiMH batteries were frequently used in prior-generation electric and hybrid-electric vehicles; as of 2020 they have been superseded almost entirely by lithium-ion batteries in all-electric and plug-in hybrid vehicles, but they remain in use in some hybrid vehicles (2020 Toyota Highlander, for example).

Panasonic's fourth-generation Eneloop batteries, in AA and AAA sizes Panasonic Eneloop Smart & Quick Charger BQ-CC55 Sanyo Eneloop battery charger. Eneloop (Japanese: エネループ, Hepburn: Enerūpu), stylized as eneloop, is a brand of 1.2-volt low self-discharge nickel–metal hydride (NiMH) rechargeable batteries and accessories developed by Sanyo [1] and introduced in 2005.
The open-circuit voltage is 1.55 V, the average voltage during discharge is 1.25 V. [9] While the energy density is only around one third as that of a lithium battery, the distinctive virtue of the nickel–hydrogen battery is its long life: the cells handle more than 20,000 charge cycles [4] with 85% energy efficiency and 100% faradaic efficiency.
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.

A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.
From January 2008 to July 2011, if you bought shares in companies when Charles M. Lillis joined the board, and sold them when he left, you would have a -75.6 percent return on your investment, compared to a -9.3 percent return from the S&P 500.
As a result of this current, the battery absorbs a charge and its voltage rises. The charger limits the maximum voltage to U max, a constant or temperature-dependent maximum, typically around 2.4 V per cell. Once the U max voltage is reached, typically when the battery is charged to 70–80% of its capacity, [1] the charger enters the Uo-phase ...
