Abstract

A battery module that includes a plurality of battery cells having cell elements that are electrically coupled. Each cell includes a first capacitor plate pair having a first capacitor plate and a second capacitor plate at a first side of the cell element. Each cell also includes a second capacitor plate pair having a first capacitor plate and a second capacitor plate positioned at a second side of the cell element. The first capacitor plate at the second side of one cell element is capacitively coupled to the first capacitor plate at the first side of the cell element in an adjacent cell and the second capacitor plate at the second side of the one cell element is capacitively coupled to the second capacitor plate at the first side of the cell element in the adjacent cell so as to provide DC breaking.
