  2. Load bank - Wikipedia

    en.wikipedia.org/wiki/Load_bank

    A resistive/reactive inductive and/or capacitive load is often required to test solar inverters to ensure solar panels can be stopped from producing electricity in the event of a power outage. The resistive/reactive combination load banks are used to test the engine generator set at its rated power factor. In most cases this is 0.8 power factor ...

  3. AirPower (Apple) - Wikipedia

    en.wikipedia.org/wiki/AirPower_(Apple)

    A non-functional late stage prototype of the AirPower displayed with an iPhone X, Apple Watch, and AirPods case. AirPower is an unreleased wireless charging mat developed by Apple Inc. It was designed to charge up to three devices simultaneously, supporting two Qi devices, such as an iPhone and AirPods, and an Apple Watch. It was announced on ...

  4. Quick Charge - Wikipedia

    en.wikipedia.org/wiki/Quick_Charge

    Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage. Quick Charge is supported by devices such as mobile phones which run on Qualcomm system-on-chip (SoCs), and by some chargers; both device and ...

  5. Induction generator - Wikipedia

    en.wikipedia.org/wiki/Induction_generator

    An induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce electric power. Induction generators operate by mechanically turning their rotors faster than synchronous speed.

  6. Emergency power system - Wikipedia

    en.wikipedia.org/wiki/Emergency_power_system

    The loss of normal power also triggers a battery operated starter system to start the generator, similar to using a car battery to start an engine. Once the transfer switch is switched and the generator starts, the building's emergency power comes back on (after going off when normal power was lost).

    A power crisis in Bangladesh prompts the government to order the partial shut-down of natural gas stations in and near Dhaka. (BBC) Fires destroy homes, amid ongoing drought in Central Brazil in Chapada dos Veadeiros National Park .

  8. Supercapacitor - Wikipedia

    en.wikipedia.org/wiki/Supercapacitor

    The electrochemical charge storage mechanisms in solid media can be roughly (there is an overlap in some systems) classified into 3 types: Electrostatic double-layer capacitors (EDLCs) use carbon electrodes or derivatives with much higher electrostatic double-layer capacitance than electrochemical pseudocapacitance, achieving separation of charge in a Helmholtz double layer at the interface ...

  9. Start-stop system - Wikipedia

    en.wikipedia.org/wiki/Start-stop_system

    A start-stop system off button on a Perodua Myvi. A vehicle start-stop system or stop-start system (also known as S&S, micro hybrid, or micro hybrid electric vehicle (μHEV)) [1] automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions.
