  2. Float voltage - Wikipedia

    en.wikipedia.org/wiki/Float_voltage

    Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]

  3. State of charge - Wikipedia

    en.wikipedia.org/wiki/State_of_charge

    In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready. [5]

  4. Electric car charging methods - Wikipedia

    en.wikipedia.org/wiki/Electric_car_charging_methods

    Electric car charging at National Air and Space Museum, 12 December 2016. Various methods exist for recharging the batteries of electric cars.Currently, the largest concern surrounding electric vehicle transportation is the total travel range available before the need to recharge.

  5. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    An intelligent charger may monitor the battery's voltage, temperature or charge time to determine the optimum charge current or terminate charging. For Ni–Cd and Ni–MH batteries , the voltage of the battery increases slowly during the charging process, until the battery is fully charged.

  6. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

  7. IUoU battery charging - Wikipedia

    en.wikipedia.org/wiki/IUoU_battery_charging

    For example, for a battery with C = 40 Ah, a current C/10 is equal to 4 A. The charging current is a compromise between charging time (favoring high currents), the prevention of damage due to overheating or outgassing (favoring low currents), and cost of the charger (favoring low currents). Recommendations for the maximum charging current vary ...

  8. Lithium-titanate battery - Wikipedia

    en.wikipedia.org/wiki/Lithium-titanate_battery

    A lithium-titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals, instead of carbon, on the surface of its anode.This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly.

  9. 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.
