Constant charge generation cycle

In a Constant Charge generation cycle, the charges are introduced after the film is stretched and kept constant. The electrical energy at any time after charging is given by the equation ... 

In terms of life-cycle costs, batteries are usually the most expensive component of a RAPS system and, therefore, it is advantageous to minimize the required capacity. The battery should, however, be sized to supply a significant portion of the anticipated daily load in the absence of diesel- or PV-generated power, e.g., from 20 to 50%. This would allow the diesel to remain idle for much of the day and to operate under relatively constant, high-load conditions for only a few hours each day. Further, the battery should be sized such that the daily depth-of-discharge (DoD) is limited in the interest of enhancing battery cycle-life. (The cycle-life of a battery is affected by several factors which include DoD, temperature, and charging procedure.)...
