plate capacitor where the most important

aim is to obtain electrodes with an extre-

mely large surface. For this purpose activa-

ted carbon is ideally suited, as it allows to

achieve capacitance values of up to 100 F/

g of active mass of the electrode. The elec-

trolyte, the conductive liquid between the

electrodes is a conducting salt dissolved in

an aqueous or organic solvent which per-

responding 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

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

film. This phenomenon represents the main

reason for the limited voltage capability

of 2.5 V only and the steep decrease of

capacitance versus frequency exhibited by

Double-Layer Capacitors.

must not exceed 2.5 V (decomposition of

the electrolyte!) Hence, series connections

need in any case to be balanced since a

possibly slightly different aging of the indi-

vidual 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

source. That means if the comparator

circuit detects a commencing overload of

any cell individual discharge is initiated by

a bypass resistor. Except the leakage cur-

rent of the cells there are no considerable

losses created during active balancing.

Application Examples

bridging during start of a fuel cell working

as emergency power supply, generally a

few 100 kJ of electrical energy are required

for a system start time of approx. 10 to

20 sec. The stored energy time is approxi-

mately 20 s. Due to the system voltage of

48 V, 22 cells of 1200 F are cascaded in a

module to achieve the setpoint voltage in

in a tight network but supplied with fuel

the new double-layer capacitors would

provide a solution. Right now tests are run

rator, however, immediately supplies them

with electrical energy again.

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. 1300 A are quite usual which can

be covered by capacitor units of 450 to

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 recup-

eration 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

100 km/h to 0 km/h 400 kJ are released,

for 10 tons it is ten times as much. So far

no suitable high-energy storage devices

were available (guideline values: 500 A

to 1000 A). 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.
