Four types of unintended storage cycling
(A) Type 1: Storage charging equals discharging.
(B) Type 2: Storage discharging exceeds charging.
(C) Type 3: Storage charging exceeds discharging; discharging exceeds same-period unintendedly cycled energy.
(D) Type 4: Storage charging exceeds discharging; but not the full cycling potential is exploited.
