Cable system for cable condition monitoring

A method for manufacturing a cable system for cable condition monitoring, the method comprising:

• providing a first adapter unit;
• providing a first sleeve unit comprising a first sensor unit;
• providing a cable comprising at least a first end portion;
• and
• arranging the first sleeve unit between the first adapter unit and the first end portion of the cable;
• wherein the first adapter unit is connectable to an energy storage system;
• wherein the cable is configured for transferring electric power to the first adapter unit;
• wherein the first sleeve unit is configured for providing protection between the first adapter unit and the cable;
• wherein the first sensor unit is configured for generating data based on strain exerted on the first sleeve unit;
• and
• wherein the first sensor unit comprises a first flexible electronic element extending at least partially to the first end portion of the cable.

A method for operating a cable system comprising a first adapter unit, a first sleeve unit, a cable comprising at least a first end portion, wherein the first adapter unit is connectable to an energy storage system, wherein the cable is configured for transferring electric power to the first adapter unit, wherein the first sleeve unit is arranged between the first adapter unit and the first end portion of the cable and configured for providing protection therebetween, wherein the first sleeve unit comprises a first sensor unit configured for generating data based on strain exerted on the first sleeve unit, and wherein the first sensor unit comprises a first flexible electronic element extending at least partially to the first end portion of the cable, and a second adapter unit and a second sleeve unit, wherein the second sleeve unit is arranged between the second adapter unit and a second end portion of the cable, and wherein the second sleeve unit comprises a second sensor unit configured for generating data based on strain exerted on the second sleeve unit, the method comprising:

• connecting the first adapter unit to the energy storage system of an electric vehicle;
• connecting the second adapter unit to a charging station and/or an energy source;
• transferring electric power from the second adapter unit to the first adapter unit via the cable;
• generating data based on strain exerted on the first sleeve unit and the second sleeve unit;
• sending generated data to a control unit via a wireless communication;
• and
• estimating an aging state of the cable based on the generated data.
