Memory effect, also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium rechargeable batteries that causes them to hold less charge. [ 1 ] [ 2 ] It describes the situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly recharged after ...
These effects explain why the voltage of a discharged battery bounces back up after the load is removed, [3] and why it is possible to discharge the battery further (e.g. turning a flashlight on again after exhausting the battery) after a period of time without charging the battery.
The power transformer or battery-to-grid are critical aspects of power distribution and sizing and modelling of batteries or transformers depends on the load profile. [1] The factory specification of transformers for the optimization of load losses versus no-load losses is dependent directly on the characteristics of the load profile that the ...
In the electrical distribution field this typically occurs on a medium voltage electrical distribution network of transformers (inductive component) and power cables (capacitive component). If such a network has little or no resistive load connected and one phase of the applied voltage is then interrupted, ferroresonance can occur.
Since electrical energy is a form of energy that cannot be effectively stored in bulk, it must be generated, distributed, and consumed immediately. When the load on a system approaches the maximum generating capacity, network operators must either find additional supplies of energy or find ways to curtail the load, hence load management.

When power is extracted continuously voltage decreases in a smooth curve, but the recovery effect can result in the voltage partially increasing if the current is interrupted. [2] The KiBaM battery model [3] describes the recovery effect for lead-acid batteries and is also a good approximation to the observed effects in Li-ion batteries.
