Why potential window becomes shorter in Galvanostatic Charge Discharge (GCD) compared to Cycling Voltammetry (CV)?

I use iviumsoft for CV and GCD in order to measure electrochemical properties of supercapacitor electrode material. Let's say that CV curves make pretty large shape in potential window of 0 to...
