4 It charges slowly and discharges quickly. 1. Equalization of input electric power. In order supply a momentary large discharge of power, the Electric Double Layer Capacir (EDLC) is added the maximum power supply output (Note: if high power is not needed, a large power supply output will worsen tal efficiency). Rapid charge & discharge of the EDLC is possible and with little charge discharge degradation, the EDLC is the the best solution.

5 It charges quickly and discharges slowly (uniformly). 2. Equalization of output electric power. An Electric Double Layer Capacir (EDLC) has extraordinarily higher capacitance compared a common capacir also float charge and fault electric discharge from a battery, it is the the best for absorption of change and equalization of the big electric power in a big span.

6 It charges quickly and discharges quickly. 3. Regeneration of wasted electric power. In an application in which a round trip, up-and-down motion, or start-sp is repeated, the energy generated at the time of the opposite direction of work is typically wasted. If the energy can be recovered, it is possible use that energy as a supplement power source for the forward direction operation. In order recover efficiently, the Electric Double Layer Capacir (EDLC), which can be rapidly charged & discharged due it's low internal resistance. Conceptual diagram Without energy regeneration Power supply Load Unrecovered, the energy potential is lost With energy regeneration Energy cannot be recovered and is Current wave form example Efficiency goes up Power supply Load Charge (regeneration) current Current wave form example EDLC Regeneration Discharge current Charge (regeneration) current EDLC current wave type Application Examples: Elevar Heavy Duty Construction & Farm Equipmen Railroad Vehicles

7 It is maintenance-free and highly reliable. 4. A reliable power supply for emergencies. Generally, an Electric Double Layer Capacir (EDLC) has the following advantages as compared a battery (in addition low internal resistance): a. Unlimited charge and discharge cycles. b. Wide operating temperature range. c. Low capacitance loss over life of product. d. Even with a decline in capacitance, the EDLC will be usable max voltage. An EDLC is ideal as a source of backup power with long-term reliability. Application Examples: Uninterruptable Power Supply (UPS) Emergency actuar drive (power failure) Circuit operation in case of power failure (IC, a memory card drive, HD drive, LED drive (Combination with a solar battery) Memory backup of real-time clock (RTC) etc. User interaction is not required. 5. Discharge time required is pre-set. If voltage output declines, in a linear method, an Electric Double Layer Capacir (EDLC) can be used set the operational time by choosing a specific capacitance value. Essentially the EDLC becomes a power supply, without the need for a Discharge time, voltage, and capacitance is shown in the following formulas: For constant current discharge: t :Discharge time t = C X ( V 0 - V 1 ) / I C :Capacitance I :Discharge current For constant resistance R :Load resistance (load) discharge: V 0 :Charge voltage t = - C X R X ln ( V 1 / V 0 ) V 1 :After discharge voltage Application Examples: Electric y PC Projecr cooling fan
