Charge and discharge efficiency
WebA higher equivalent series resistance (ESR) also leads to a large voltage drop (IR-drop) at each half-cycle, which dramatically reduces power and capacity. The damage has greatly decreased the efficiency of this EDLC. Gamrys Cyclic Charge-discharge Software. Figures 1 and 2 showed individual charge and discharge curves. WebThe long and large-diameter uncharged hole-boring (LLB) method is a cut-blasting method used to reduce vibration induced by blasting. This method typically involves creating an uncharged hole with a 382 mm diameter and drilling 50 m in the tunnel excavation direction at a time. This method is reported to provide relatively good vibration reduction and with …
