  2. IUoU battery charging - Wikipedia

    en.wikipedia.org/wiki/IUoU_battery_charging

    Stage 3 is called the U-phase or float charge state, the voltage is reduced to a value that is safe to be applied for long periods (weeks) without significantly reducing the lifetime of the battery. During this phase, the charge current decreases gradually to a small residual value that compensates for any self-discharge of the battery.

  3. Cutoff voltage - Wikipedia

    en.wikipedia.org/wiki/Cutoff_voltage

    A high cut-off voltage is more widespread than perhaps assumed. For example, a certain brand of mobile phone that is powered with a single-cell Lithium-ion battery cuts off at 3.3 V. The Liion can be discharged to 3 V and lower; however, with a discharge to 3.3 V (at room temperature), about 92–98% of the capacity is used. [2]

  5. Lithium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Lithium-ion_battery

    A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

  6. 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]

  7. Lithium–silicon battery - Wikipedia

    en.wikipedia.org/wiki/Lithium–silicon_battery

    Lithium–silicon batteries are lithium-ion batteries that employ a silicon-based anode, and lithium ions as the charge carriers. [1] Silicon based materials, generally, have a much larger specific capacity, for example, 3600 mAh/g for pristine silicon. [ 2 ]

  8. Lithium–sulfur battery - Wikipedia

    en.wikipedia.org/wiki/Lithium–sulfur_battery

    [2] [4] [1] Li–S batteries offer specific energies on the order of 550 Wh/kg, [1] while lithium-ion batteries are in the range of 150–260 Wh/kg. [5] Li–S batteries with up to 1,500 charge and discharge cycles were demonstrated in 2017, [6] but cycle life tests at commercial scale and with lean electrolyte have not been completed. As of ...

  9. Depth of discharge - Wikipedia

    en.wikipedia.org/wiki/Depth_of_discharge

    While the state of charge is usually expressed using percentage points (0 % = empty; 100 % = full), depth of discharge is either expressed using units of Ah (e.g. for a 50 Ah battery, 0 Ah is full and 50 Ah is empty) or percentage points (100 % is empty and 0 % is full). The capacity of a battery may also be higher than its nominal rating.
