Does Tesla charging pile cable 14 meters long consume electricity?

yes.

Cable is a new type of cable introduced by BeldenCDT Company, which is a leader in the wiring industry. The cable adopts unshielded twisted pair, supports high-definition video transmission, accurate data transmission and KVM technology, and is the best solution for professional video and data applications. At the same time, it provides excellent low offset performance for component video applications, which conforms to and is suitable for TIA/EIA standards.

when the temperature drops, the storage capacity of some batteries will decrease. The battery has been used for a long time and the electrode plate is aging. Motor, if the motor is old, the carbon brush is badly worn, the bearing is not lubricated well, etc., it will consume a lot of electric energy and the input mechanical energy is insufficient.
