  2. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

    The battery management system on the electric vehicle negotiates the maximum current with the electric vehicle supply equipment via dedicated pins in the Type 3C connector. The Type 3 (3A/3C) connectors are generally oval in shape, with circular top and bottom edges and flat right and left edges; the maximum power carried is 24 kW.

  5. 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 ...

  6. 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.

  7. 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.
