Li-ion battery and dc-link capacitor technologies – Electric drivetrain applications : A literature study

• Modern electrical vehicle drivetrains use a DC-link capacitor to decouple the battery from the power electronics.This topology is thought to be necessary for a number of reasons, including among others preventing damage to the battery and reducing electromagnetic interference.However, the DC-link capacitor is a bulky component which makes the entire drivetrain less modular by its presence.For this reason, an interdisciplinary research project has been launched to investigate the possibility of improving electrical vehicle drivetrains by having PhD students from the fields of electrical engineering and applied electrochemisty working closely together.The initial goal of this project will be to attempt to remove the DC-link capacitor entirely, in order to determine whether this adversely affects the battery longevity.Depending on the results from this initial test, other potential problems with removing the DC-link capacitor will be identfied and addessed.
