Battery system having battery cells and an apparatus for controlling the temperature of the battery cells

摘要

A battery system includes a plurality of battery cells connected to one another and includes an apparatus configured to control the temperature of the plurality of battery cells. The apparatus includes at least one hollow body through which a coolant flows and includes at least one heat conducting element having at least one first contact region and at least one second contact region. The at least one first contact region has a planar configuration and is in thermal contact with a side face of at least one battery cell of the plurality of battery cells. The at least one second contact region is arranged on the at least one hollow body such that the at least one second contact region is in thermal contact with the at least one hollow body.
