Method for introducing a heat-conducting compound into a battery module and injection arrangement

An injection arrangement for introducing a first heat-conducting compound into at least one first free space in a battery module, comprising:

• a battery module having a module housing and a cell pack arranged in the module housing and having at least one battery cell, wherein the module housing has a first housing side and a second housing side opposite to the first housing side, wherein the cell pack has a first side which faces toward the first housing side and a second side opposite to the first side, which faces toward the second housing side, wherein the cell pack is arranged in the housing in such a way that the first free space is between the first side of the cell pack and the first housing side and a second free space is between the second side and the second housing side;
• an injection device which is designed to fill the first heat-conducting compound into the first free space;
• wherein
• the injection device is designed to fill the first heat-conducting compound into the first free space and a second heat-conducting compound into the second free space overlapping in time.
