Line installation device for a high-voltage battery of a motor vehicle, line arrangement, high-voltage battery and motor vehicle

A high-voltage battery system comprising:

• a high-voltage battery of a motor vehicle;
• a line installation device that is configured to lay lines of the high-voltage battery on at least one battery module of the high-voltage battery;
• a line clip configured to retain at least a first line and configured to retain a second line, wherein
• the first line is an electrical line,
• the second line is a coolant line,
• the line clip is configured to guide the first line and the second line as a line bundle over a given side of the at least one battery module,
• the given side has degassing openings of battery cells of the at least one battery module,
• the line clip contains a refractory material configured to protect the first line and the second line against a hot gas which passes out of the degassing openings,
• the line clip has a bottom part, which faces a side with the degassing openings of the at least one battery module, and a top part which is situated opposite the bottom part,
• the first and second lines are arranged between the bottom part and the top part,
• at least one outer side, which faces the side with the degassing openings of the at least one battery module, is formed from the refractory material,
• the bottom part has at least one passage opening configured to guide a coolant connection of the at least one coolant line through to at least one coolant nozzle of a cooling device of the at least one battery module, and
• wherein the line clip is arranged between two degassing openings of two adjacent battery cells of the at least one battery module.
