  2. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    If the cells of a battery are connected in parallel, the battery voltage will be the same as the cell voltage, but the current supplied by each cell will be a fraction of the total current. For example, if a battery comprises four identical cells connected in parallel and delivers a current of 1 ampere , the current supplied by each cell will ...

    en.wikipedia.org/wiki/Uninterruptible_power_supply

    The transformer has three windings, one for ordinary mains power, the second for rectified battery power, and the third for output AC power to the load. This once was the dominant type of UPS and is limited to around the 150 kVA range. These units are still mainly used in some industrial settings (oil and gas, petrochemical, chemical, utility ...

    Parallel hybrids can be further categorized by the balance between the different motors are at providing motive power: the ICE may be dominant (engaging the electric motor only in specific circumstances) or vice versa; while in others can run on the electric system alone but because current parallel hybrids are unable to provide electric-only ...

  5. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    In a series configuration, if a single battery dies, the other batteries will not be able to power the load. Parallel configuration If the goal is to increase capacity and prolong the runtime of the inverter, batteries can be connected in parallel. This increases the overall ampere hour (Ah) rating of the battery set.

  6. Anderson Powerpole - Wikipedia

    en.wikipedia.org/wiki/Anderson_Powerpole

    The specific hermaphroditic nature of the powerpoles is a significant advantage since batteries can be both a power source or a power sink, a power supply can be connected to a radio and/or a battery, and multiple batteries, radios, and/or redundant power sources can be connected in parallel using the same power distribution panels.

  7. Battery pack - Wikipedia

    en.wikipedia.org/wiki/Battery_pack

    A power bank is a portable device consisting of a battery, a charger to interface battery with charging power source and an output interface to provide desired output voltage. [10] Power banks are made in various sizes and typically based on lithium-ion batteries. A power bank contains battery cells and a voltage converter circuitry.

  8. Power electronics - Wikipedia

    en.wikipedia.org/wiki/Power_electronics

    In hybrid electric vehicles (HEVs), power electronics are used in two formats: series hybrid and parallel hybrid. The difference between a series hybrid and a parallel hybrid is the relationship of the electric motor to the internal combustion engine (ICE). Devices used in electric vehicles consist mostly of dc/dc converters for battery ...

  9. Hybrid vehicle - Wikipedia

    en.wikipedia.org/wiki/Hybrid_vehicle

    In a power-split hybrid electric drive train, there are two motors: a traction electric motor and an internal combustion engine. The power from these two motors can be shared to drive the wheels via a power split device, which is a simple planetary gear set. The ratio can be from 100% for the combustion engine to 100% for the traction electric ...
