  2. State of health - Wikipedia

    en.wikipedia.org/wiki/State_of_health

    State of health (SoH) is a figure of merit of the condition of a battery (or a cell, or a battery pack), compared to its ideal conditions. The unit of SoH is percent (100% = the battery's conditions match the battery's specifications).

  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. Depth of discharge - Wikipedia

    en.wikipedia.org/wiki/Depth_of_discharge

    the fraction of the battery's capacity which is currently removed from the battery with regard to its (fully) charged state. For fully charged batteries, the depth of discharge is connected to the state of charge by the simple formula D o D = 1 − S o C {\displaystyle \mathrm {DoD} =1-\mathrm {SoC} } .

    To adjust a 14 MOA scope 3 MOA down and 1.5 MOA right, the scope needs to be adjusted 3 x 4 = 12 clicks down and 1.5 × 4 = 6 clicks right; To adjust a 1 ⁄ 8 MOA scope 3 MOA down and 1.5 MOA right, the scope needs to be adjusted 3 x 8 = 24 clicks down and 1.5 × 8 = 12 clicks right; Comparison of minute of arc (MOA) and milliradian (mrad).

  6. 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 ...

    For a lead–acid battery is typically between 1.1 and 1.3. For different lead–acid rechargeable battery technologies it generally ranges from 1.05 to 1.15 for VRSLAB AGM batteries, from 1.1 to 1.25 for gel, and from 1.2 to 1.6 for flooded batteries. The Peukert constant varies with the age of the battery, generally increasing (getting worse ...

  8. TI-57 - Wikipedia

    en.wikipedia.org/wiki/TI-57

    The TI-57 lacked non-volatile memory, so any programs entered were lost when the calculator was switched off or the battery ran out. The LED display version of the TI-57 had a rechargeable Nickel-Cadmium battery pack BP7 which contains two AA size batteries and electronics to raise the voltage to the 9V required by the calculator.

  9. Ampere-hour - Wikipedia

    en.wikipedia.org/wiki/Ampere-hour

    For example, at 3.2 V for a lithium iron phosphate battery cell (LiFePO 4), the perceived energy capacity of a small UPS product that has multiple DC outputs at different voltages but is simply listed with a single ampere-hour rating, e.g., 8800 mAh, would be exaggerated by a factor of 3.75 compared to that of a sealed 12-volt lead-acid battery ...
