EDLC and Battery Coupling (Continued)
Under conditions of high power and short duration current pulses, a volt-
age damping effect will be achieved. The voltage drop of the
battery will be decreased resulting in better energy management and
superior energy density of the battery (Fig. 6).
The power supplied will be produced by both the EDLC and the
battery, and each will supply the relative power inversely to its own ESR.
The inefficiency of batteries at lower temperatures is well known.
The capacitance of most batteries decreases with decreasing
temperatures.
This decrease is due to the slow kinetics of the chemical reaction in the
battery which increases the internal resistance of the battery.
At low temperatures, the voltage drop of the battery increases and
reduces the usefulness of the battery. This voltage drop can be
reduced greatly by coupling of the battery and the EDLC.
In conclusion, coupling the battery and EDLC results in superior power
management for many short interval and high power
applications.
