  2. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.

  3. Uninterruptible power supply - Wikipedia

    en.wikipedia.org/wiki/Uninterruptible_power_supply

    If a battery has been completely discharged (e.g. the car lights were left on overnight) and next is given a fast charge for only a few minutes, then during the short charging time it develops only a charge near the interface. The battery voltage may rise to be close to the charger voltage so that the charging current decreases significantly.

  4. Busbar - Wikipedia

    en.wikipedia.org/wiki/Busbar

    In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks. They are generally ...

  5. Battery management system - Wikipedia

    en.wikipedia.org/wiki/Battery_management_system

    A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...

  6. Ground loop (electricity) - Wikipedia

    en.wikipedia.org/wiki/Ground_loop_(electricity)

    The diagram shows leakage current from an appliance such as an electric motor A flowing through the building's ground system G to the neutral wire at the utility ground bonding point at the service panel. The ground loop between components C1 and C2 creates a second parallel path for the current. [8]

  7. Through service - Wikipedia

    en.wikipedia.org/wiki/Through_service

    The term through service may be extended to have a wider meaning encompassing a route which allows the passenger to travel without alighting, for example, in a route change announcement, if a route A-B and a route B-C is combined to A-B-C, it may be described as a new "through service" between A and C. [1] [2] This is in contrast with direct ...

  9. Grid-tied electrical system - Wikipedia

    en.wikipedia.org/wiki/Grid-tied_electrical_system

    A key concept of this system is the possibility of creating an electrical micro-system that is not dependent on the grid-tie to provide a high level quality of service. If the mains supply of the region is unreliable, the local generation system can be used to power important equipment.
