Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge". A "charge cycle" is not a unit of time; the length of time spent charging or discharging does not affect the number of charge cycles. [ 1 ]
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.
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.
The voltage in the U o-phase is too high to be applied indefinitely (hence, overvoltage), but it allows charging the battery fully in a relatively short time. The U o-phase is concluded when the charge current goes below a threshold I min, after which the U-phase is entered. This happens when the battery is charged to around 95% of its capacity ...
The charge controller detects the high voltage of a nearly fully charged string and reduces current flow. The new cells with more capacity now charge very slowly, so slowly that the chemicals may begin to crystallize before reaching the fully charged state, reducing new cell capacity over several charge/discharge cycles until their capacity ...
In a much-anticipated Department of Justice report, Jack Smith says he stands fully behind his decision to criminally charge President-elect Donald Trump. “The throughline of all of Mr. Trump ...
Typically a battery is constant current charged at 1 CA rate until all the cells have reached at least 1.55 V. Another charge cycle follows at 0.1 CA rate, again until all cells have reached 1.55 V. The charge is finished with an equalizing or top-up charge, typically for not less than 4 hours at 0.1 CA rate.
