  2. Battery balancing - Wikipedia

    en.wikipedia.org/wiki/Battery_balancing

    A battery balancer or regulator is an electrical device in a battery pack that performs battery balancing. [2] Circuitry that includes designs to balance cell charges during battery pack recharging may be either active or passive in its design, [ 3 ] and is most often found in lithium-ion batteries , [ 4 ] e.g., for laptop computers, electrical ...

  3. Jelly roll (battery) - Wikipedia

    en.wikipedia.org/wiki/Jelly_roll_(battery)

    The jelly roll or Swiss roll design is the design used in the majority of cylindrical rechargeable batteries, including nickel–cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), and lithium-ion (Li-ion). The design has this name because the cross section of the battery looks like a Swiss roll.

  5. 18650 battery - Wikipedia

    en.wikipedia.org/wiki/18650_battery

    An 18650 battery [1] or 1865 cell [2] is a cylindrical lithium-ion battery common in electronic devices. The batteries measure 18 mm (0.71 in) in diameter by 65 mm (2.56 in) in length, giving them the name 18650. [3] The battery comes in many nominal voltages depending on the specific chemistry used.

    Nissan Leaf cutaway showing part of the battery in 2009. An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.

  7. Rechargeable battery - Wikipedia

    en.wikipedia.org/wiki/Rechargeable_battery

    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.

  8. Trickle charging - Wikipedia

    en.wikipedia.org/wiki/Trickle_charging

    Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, 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.

  9. Charge controller - Wikipedia

    en.wikipedia.org/wiki/Charge_controller

    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 ...
