For this purpose activated carbon is ideally suited, as it allows to achieve capacitance values of up to 100F/ 100F/ g of active mass of the electrode. The electrolyte, the conductive liquid between the electrodes is a conducting salt dissolved in an aqueous or organic solvent which permits to apply voltages of 2.5V. Construction principle of the WIMA Double-Layer Capacitor The actual double-layer consists of ions which, when voltage is applied, attach to the positive or negative electrode corresponding to their opposite poles and thus create a dielectric gauge of a few Angstrom only. This results in a very high capacitance yield caused by the very huge surface of the electrode in accordance with the formula This phenomenon represents the main reason for the modest AC voltage capability and the steep decrease of capacitance versus frequency exhibited by DoubleLayer Capacitors. Cascaded SuperCap Modules Several SuperCap cells can be built up to enormous capacitances of the desired voltage by means of series or parallel connection (cascade). When cascading SuperCaps, the voltage of single cells must not exceed 2.5V (decomposition of the electrolyte!) Hence, series connections need in any case to be balanced since a possibly slightly different aging of the individual cells due to temperature may over time cause deviating capacitances and thus different voltage drops at the cell. The balancing will be factory-mounted into a module. This can be made passively and in a cost-efficient way by simple resistors in those cases where additional losses as bypass current through the balancing resistors can be tolerated by the application. Alternatively, an active balancing can be made by keeping each cell at a certain voltage by means of a reference source. That means if the comparator circuit detects a commencing overload of any cell individual discharge is initiated by a bypass resistor. Except the current needed for the voltage dividier and the minimal leakage current of the cells there are no considerable losses created during active balancing. Active balancing. Comparator compares voltage at the capacitor by a reference voltage and switches in order to discharge through a bypassing resistor until overvoltage has declined. Operational Life For physical reasons it is unavoidable that Double-Layer Capacitors are subjected to aging which follows the logarithmic dependence of voltage applied and ambient temperature (Arrhenius behaviour) that can be observed with other components, too. However, continuous studies have shown that WIMA products exhibit a significantly improved behaviour in terms of life time being achieved by a laser-welded, hermetically sealed construction of the cells in metal cases which makes penetration from outside impossible; they cannot dry up and can withstand a certain thermal expansion movement. Only by this innovation one can consider the component being suitable for long-year maintenance-free application. = e x Surface C Distance To visualise this, the internal surface of a Double-Layer Capacitor would cover several football pitches. Passive balancing. Without resistors: U reciprocal-effect to C - thus locale overvoltage easily can occur With resistors: U proportional-effect to R - thus voltage is fixed 11.10 A permeable diaphragm acting as a separating layer and called separator avoids short-circuit between the two electrodes and considerably influences the characteristics of the capacitor. Charge or discharge of the Double-Layer Capacitor is combined with the transformation of the layers in the electrical field and thus with the movement of the charge carriers in the solvent - even through the separator film. 110 D Technical Data and Applications of WIMA Double-Layer Capacitors (Continuation) When properly treated WIMA SuperCaps have a service life beyond 10 years and can easily sustain more than 500.000 charge/discharge cycles. The efficiency is far higher than 90%. Application Examples In general Double-Layer Capacitors are applied for voltage support, for saving or for replacing conventional battery or charger solutions. The typical application is the quick supply of several 100A to 1000A in the direct current field. Slip Control in Wind Power Life time expectancy for WIMA SuperCaps Advantages in Comparison with other Energy Storage Solutions WIMA SuperCaps are showing foIlowing advantages in comparison with other energy storage solutions: " Low internal resistance (less than 1/10 of what a usual battery exhibits) " Release of high currents (10 to 100 times more than batteries) " Maintenance-free operation " No risk of damage due to complete discharge of the component " igh life expectancy H " Usage in isolated systems, e.g. inac cessible areas, is unproblematic " Comparatively low weight WIMA Double-Layer Capacitors are particularly suitable in applications where high and even highest currents - not in pure AC operation - occur. By combining the advantage of conventional capacitors as fast suppliers of electricity with that of batteries as notable energy reservoirs the SuperCap represents the link between battery and conventional capacitor. Start of Micro-Turbines, Fuel Cells or Diesel-Electric Generator working as Power Set For micro-turbines driven with natural gas for generation of electrical energy on oil platforms, in part also for gas pumping stations, in sensible areas like hospitals and huge factories the use of SuperCap modules to replace conventional starter batteries (by experience needing replacement every 2 to 3 years) is the optimum choice. Usually about 300kJ of electrical energy at a system voltage of 240V are needed for a turbine start-up time of 10 to 20s. When starting special micro-turbines or for bridging during start of a fuel cell working as emergency power supply, generally a few 100kJ of electrical energy are required for a system start time of approx. 10 to 20sec. The stored energy time is approximately 20s. Due to the system voltage of 48V, 22 cells of 1200F 1200F are cascaded in a Starting huge Railway, Naval or Truck Motors The start of V16 or V24 cylinder motors (6000 kW), e.g. for generator drives of diesel-electric trains or start of a naval diesel engine requires considerably high currents. 1300A are quite usual which can be covered by capacitor units of 450 to 600F at 28V. Frequently the crankshaft is turned by two starters on both sides (e.g. 7kW each with a positive switch off after 9s for 2min), in order to avoid torsion of the huge mass. The low total internal resistance of less then 3m¸ which is beyond reach for batteries the capacitor solution is outstanding. Recuperation of Braking Energy In times of resource shortage of fuel the highest possible recuperation of braking energy is a challenging aim. While recuperation in electric train drives or in hybrid busses is already practiced since long, for non-mains connected vehicles the energy recuperation to the on-board battery has only be realized to the extent of few per cent. The basic reason is the charge current limitation of batteries where the recuperable energy is obtained at very high currents in a scope of milliseconds. If for example 1 ton shall be decelerated from 100km/h to 0km/h 400kJ are released, for 10 tons it is ten times as much. So far no suitable high-energy storage devices were available (guideline values: 500A to 1000A). This is the domain of the new SuperCaps since in the foreseeable future even most modern battery systems will not be in a position to cope with such energy. 11.10 Standard SuperCap Battery Capacitor Capacitance< 1m F/cm 2 1000000 m F per Surface (1F/cm 2) Energy- < 0.01Wh/kg< 10Wh/kg 100Wh/kg density < 0.1kW/kg > 1kW/kg 0.1kW/kg Power- density In large-scale wind turbine systems, slip controllers are used to control the rotation speed by altering the angle of the rotor blades. The drives are mains-independent and if electrically controlled use the energy stored in batteries or double-layer capacitors. These storage devices have to meet stringent requirements. During winter time the temperatures in the wind tower top housing often reach around -40°C, and during summer time they may easily go up to more than +60°C during operation. The current of 200A necessary for the breakaway torque of e.g. a 3kW motor presents big problems to batteries due to the ambient conditions described. Their short life time and frequently necessary maintenance renders them unsatisfactory. However, when properly dimensioned, modern SuperCap solutions enable a maintenance-free usage of the electrical storage device of minimum 10 years. module to achieve the setpoint voltage in order to replace a battery block. For start-up of generators for energy supply of autonomous telecommunication stations which are located decentrally in a tight network but supplied with fuel the new double-layer capacitors would provide a solution. Right now tests are run with 14V series connections (70 to 100F) which should render a maintenance-free service. After three starting processes in a sequence their energy with 300 to 500A each flowing (depending on the size of the motor) is used up. The now running generator, however, immediately supplies them with electrical energy again. 111 D WIMA Part Number System A WIMA part number consists of 18 digits and is composed as follows: Field 1 - 4:Type description Field 5 - 6:Rated voltage Field 7 -10:Capacitance Field11 -12:Size and PCM Field13 -14:Special features (e.g. Snubber versions) Field15: Capacitance tolerance Field16: Packing Field17 -18:Lead length (untaped) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 M K S 2 C 0 2 1 0 0 1 A 0 0 M S S D 20 % bulk MKS 2 11.10 Type description: SMD-PET = SMD-PPS = FKP 02 = MKS 02 = FKS 2 = FKP 2 = MKS 2 = MKP 2 = FKS 3 = FKP 3 = MKS 4 = MKP 4 = MKP 10 = FKP 4 = FKP 1 = MKP-X2 = MKP-X2 R = MKP-Y2 = MP 3-X2 = MP 3-X1 = MP 3-Y2 = MP 3R-Y2 = Snubber MKP = Snubber FKP = GTO MKP = DC-LINK MKP 4 = DC-LINK MKP C = DC-LINK HC = SuperCap C = SuperCap MC = SuperCap R = SuperCap MR = 63 VDC SMDT SMDI FKP0 MKS0 FKS2 FKP2 MKS2 MKP2 FKS3 FKP3 MKS4 MKP4 MKP1 FKP4 FKP1 MKX2 MKXR MKY2 MPX2 MPX1 MPY2 MPRY SNMP SNFP GTOM DCP4 DCPC DCH_ SCSC SCMC SCSR SCMR Rated voltage: 2.5 VDC = A1 4 VDC = A2 14 VDC = A3 28 VDC = A4 40 VDC = A5 5 VDC = A6 50 VDC = B0 63 VDC = C0 100 VDC = D0 160 VDC = E0 250 VDC = F0 400 VDC = G0 450 VDC = H0 600 VDC = I0 630 VDC = J0 700 VDC = K0 800 VDC = L0 850 VDC = M0 900 VDC = N0 1000 VDC = O1 1100 VDC = P0 1200 VDC = Q0 1250 VDC = R0 1500 VDC = S0 1600 VDC = T0 2000 VDC = U0 2500 VDC = V0 3000 VDC = W0 4000 VDC = X0 6000 VDC = Y0 250 VAC = 0W 275 VAC = 1W 300 VAC = 2W 400 VAC = 3W 440 VAC = 4W 500 VAC = 5W . 0.01 mF Capacitance: 22 pF = 0022 47 pF = 0047 100 pF = 0100 150 pF = 0150 220 pF = 0220 330 pF = 0330 470 pF = 0470 680 pF = 0680 1000 pF = 1100 1500 pF = 1150 2200 pF = 1220 3300 pF = 1330 4700 pF = 1470 6800 pF = 1680 0.01 mF = 2100 0.022 mF = 2220 0.047 mF = 2470 0.1 mF = 3100 0.22 mF = 3220 0.47 mF = 3470 = 4100 1 mF 2.2 mF = 4220 4.7 mF = 4470 = 5100 10 mF = 5220 22 mF = 5470 47 mF 100 mF = 6100 220 mF = 6220 1F = A010 2.5 F = A025 50 F = A500 100 F = B100 110 F = B110 600 F = B600 1200 F = C120 . - 2.5 6.5 7.2 x x Size: 4.8x3.3x3 Size1812 Size1812 4.8x3.3x4 Size1812 Size1812 5.7x5.1x3.5 Size2220 Size2220 5.7x5.1x4.5 Size2220 Size2220 7.2x6.1x3 Size2824 Size2824 7.2x6.1x5 Size2824 Size2824 10.2x7.6x5 Size4030 Size4030 12.7x10.2x6 Size5040 Size5040 15.3x13.7x7 Size6054 Size6054 2.5x7x4.6 PCM2.5 3x7.5x4.6 PCM2.5 2.5x6.5x7.2 PCM5 3x7.5x7.2 PCM5 2.5x7x10 PCM7.5 3x8.5x10 PCM7.5 3x9x13 PCM10 PCM10 4x9x13 PCM10 PCM10 5x11x18 PCM15 PCM15 6x12.5x18 PCM15 PCM15 5x14x26.5 PCM22 PCM22.5 6x15x26.5 PCM22 PCM22.5 9x19x31.5 PCM27 PCM27.5 11x21x31.5 PCM27 PCM27.5 9x19x41.5 PCM37 PCM37.5 11x22x41.5 PCM37 PCM37.5 94x49x182 DCH_ 94x77x182 DCH_ .
