The invention discloses a charging cable identification method and device, a charging cable and a readable storage medium, belongs to the technical field of communication, and can solve the problems of low compatibility and high cost of the charging cable. The method comprises the steps that under the condition that the charging cable identification device is in a monitoring mode, if a first target communication port receives a charging cable identification request, a second target communication port is switched from a data receiving state to a data sending state, and charging cable identification information is sent through the second target communication port, wherein the first target communication port is one of a first communication port and a second communication port, the second target communication port is one of a first communication port and a second communication port, the second target communication port is different from the first target communication port; and the first communication port and the second communication port are both in a data receiving state in a monitoring mode. The embodiment of the invention is applied to the scene of charging the electronic equipment.
Description
technical field [0001] The embodiments of the present application relate to the technical field of communication, and in particular, to a method and device for identifying a charging cable, a charging cable, and a readable storage medium. Background technique [0002] With the development of charging technology, more and more electronic devices support fast charging. [0003] In the related art, the fast charging current is generally relatively large. In order to ensure the charging safety during the charging process, the charger or the charging device needs to detect the overcurrent capability of the charging cable before fast charging. For a fast charging protocol with a charging current greater than 3A, the E-Mark (electronically marked) chip solution is usually used to obtain the overcurrent capability of the charging cable. [0004] However, since the E-Mark chip can only communicate with one party (the charger or the charging device), the compatibility of the charging...
