  2. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    Lithium-ion rechargeable batteries (particularly laptop batteries) are often connected in parallel to increase the ampere-hour rating. Some solar electric systems have batteries in parallel to increase the storage capacity; a close approximation of total amp-hours is the sum of all amp-hours of in-parallel batteries.

  3. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    The acceleration breaks a capsule of electrolyte that activates the battery and powers the fuze's circuits. Reserve batteries are usually designed for a short service life (seconds or minutes) after long storage (years). A water-activated battery for oceanographic instruments or military applications becomes activated on immersion in water.

  4. Battery pack - Wikipedia

    en.wikipedia.org/wiki/Battery_pack

    A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. [1] [2] They may be configured in a series, parallel or a mixture of both to deliver the desired voltage and current. The term battery pack is often used in reference to cordless tools, radio-controlled hobby toys, and battery electric vehicles.

  5. Electric vehicle battery - Wikipedia

    en.wikipedia.org/wiki/Electric_vehicle_battery

    Battery packs will always incorporate many discrete cells connected in series and parallel to achieve the total voltage and current requirements of the pack. Battery packs for all electric drive EVs can contain several hundred individual cells. Each cell has a nominal voltage of 3-4 volts, depending on its chemical composition. [citation needed]

  6. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    Circuit diagram of a primary cell showing difference in cell potential, and flow of electrons through a resistor. Primary batteries make up about 90% of the $50 billion battery market, but secondary batteries have been gaining market share.

  7. Randles circuit - Wikipedia

    en.wikipedia.org/wiki/Randles_circuit

    Randles circuit schematic. In electrochemistry, a Randles circuit is an equivalent electrical circuit that consists of an active electrolyte resistance R S in series with the parallel combination of the double-layer capacitance C dl and an impedance (Z w) of a faradaic reaction.

  8. Battery balancing - Wikipedia

    en.wikipedia.org/wiki/Battery_balancing

    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 ]

  9. Equivalent circuit model for Li-ion cells - Wikipedia

    en.wikipedia.org/wiki/Equivalent_circuit_model...

    The equivalent circuit model (ECM) is a common lumped-element model for Lithium-ion battery cells. [ 1 ] [ 2 ] [ 3 ] The ECM simulates the terminal voltage dynamics of a Li-ion cell through an equivalent electrical network composed passive elements, such as resistors and capacitors , and a voltage generator .
