ULTRA-CAPACITOR
Ultra capacitor plays very essential role in the
whole system, so that the new technologies have the such
abilities to control them. In the ultra capacitor system, the
important contents are the DC-DC converter base on the
insulated gate bipolar transistor [IGBT], smoothing
aluminum inductor Ls, ultra capacitor and battery pack.
During acceleration, the capacitor voltage of ultra
capacitor permitted to set free from packed rate charge to
one-third of its nominal voltage. During deceleration, the
energy of capacitor which is released during acceleration
period is improved back and charge up the ultra capacitor.
Ultra- capacitor is mainly used because it store up 20
times more energy as evaluate to electrolytic capacitor as
shown in figure 6. Ultra capacitor also improves the
transient performance in EVs, also increase lifespan of
batteries. Ultra capacitor provides additional supply to
the electric vehicles and also extends the distance.
