1. A battery system for an electric vehicle, the battery system comprising:
a plurality of battery cells arranged in a plurality of rows, each of the battery cells comprising electrode terminals and having a venting exit;
a first busbar interconnecting adjacent ones of the battery cells in a first one of the rows by contacting the electrode terminals;
a second busbar interconnecting one of the battery cells in the first one of the rows and one of the battery cells in a second one of the rows;
a battery housing enclosing the battery cells, the battery housing comprising a top cover continuously extending over the venting exits of the battery cells; and
an electrically and thermally insulating cover element covering the electrode terminals, the first busbar, and the second busbar and having a plurality of venting openings respectively aligned with the venting exits of the battery cells such that the electrode terminals, the first busbar, and the second busbar are shielded from venting products exiting the venting exit of one or more of the battery cells towards the battery housing during a thermal runaway,
wherein the cover element is between the battery cells and the top cover, and
wherein the first busbar and the second busbar are between the electrode terminals and the cover element.
