  2. Depth of discharge - Wikipedia

    en.wikipedia.org/wiki/Depth_of_discharge

    Depth of discharge (DoD) is an important parameter appearing in the context of rechargeable battery operation. Two non-identical definitions can be found in commercial and scientific sources. The depth of discharge is defined as: the maximum fraction of a battery's capacity (given in Ah) which is removed from the charged battery on a regular basis.

  3. State of charge - Wikipedia

    en.wikipedia.org/wiki/State_of_charge

    An alternative form of the same measure is the depth of discharge , calculated as 1 − SoC (100% = empty; 0% = full). It refers to the amount of charge that may be used up if the cell is fully discharged. [ 2 ]

  4. Drainage equation - Wikipedia

    en.wikipedia.org/wiki/Drainage_equation

    Crop yield (Y) and seasonal average depth of water table (X in dm) [4] Determining: the discharge rate (Q) from the recharge rate (R) in a water balance as detailed in the article: hydrology (agriculture) the permissible long term average depth of the water table (Dw) on the basis of agricultural drainage criteria

  5. Flow in partially full conduits - Wikipedia

    en.wikipedia.org/wiki/Flow_in_partially_full...

    The variations of Q/Q (full) and V/V (full) with H/D ratio is shown in figure(b).From the equation 5, maximum value of Q/Q (full) is found to be equal to 1.08 at H/D =0.94 which implies that maximum rate of discharge through a conduit is observed for a conduit partly full.

  6. Open-channel flow - Wikipedia

    en.wikipedia.org/wiki/Open-channel_flow

    The depth changes abruptly over a comparatively short distance. Rapidly varied flow is known as a local phenomenon. Examples are the hydraulic jump and the hydraulic drop. Gradually-varied flow. The depth changes over a long distance. Continuous flow. The discharge is constant throughout the reach of the channel under consideration. This is ...

    Self-discharge rate Shelf life Anode Electro­lyte Cathode Cutoff Nominal 100% SOC by mass by volume; ... # 100% depth of discharge (DoD) cycles Lead–acid: 50–92 [2]

  8. Nickel–hydrogen battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–hydrogen_battery

    The open-circuit voltage is 1.55 V, the average voltage during discharge is 1.25 V. [9] While the energy density is only around one third as that of a lithium battery , the distinctive virtue of the nickel–hydrogen battery is its long life: the cells handle more than 20,000 charge cycles [ 4 ] with 85% energy efficiency and 100% faradaic ...

  9. Recovery effect - Wikipedia

    en.wikipedia.org/wiki/Recovery_effect

    The size of the recovery effect depends on the battery load, recovery time and depth of discharge. [ 6 ] Even though the recovery effect phenomenon is prominent in the lead acid battery chemistry, its existence in alkaline , Ni-MH and Li-Ion batteries is still questionable.
