Abstract

The invention discloses an electronic lock unlocking method during alternating current charging of an electric vehicle. A PEPS ECU detects the relative position between an intelligent key and each low-frequency antenna; the identity of the intelligent key is identified through the low-frequency antennas; the low-frequency antennas transmit the measured key coordinates to the PEPS ECU; the PEPS ECUsends a corresponding electronic lock unlocking operation instruction to a BMS through a CAN bus; after the BMS receives an unlocking operation instruction of the PEPS ECU, the BMS sends a charging current to an OBC through the CAN bus to reduce the charging current to be lower than a safety set value; and the OBC receives the instruction and reduces the output current to below a safety set valueaccording to the request of the BMS, and then an electronic lock is unlocked. By the adoption of the technical scheme, the electronic lock can be intelligently unlocked in the alternating current charging process, the electronic lock is reasonable in structure and stable and reliable in operation, and the problem that the electronic lock is not liable to plug or unsafely and randomly plugged is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of electronic lock unlocking for electric vehicles. More specifically, the present invention relates to an intelligent unlocking method for an electronic lock on an AC charging stand during AC charging of a new energy electric vehicle. Background technique [0002] There are three types of new energy electric vehicles: AC, DC, and wireless charging. Among them, the national standard mandates that an electronic lock must be installed when the AC charging current is greater than 16A. However, not all customers understand the structure of electric vehicles and the requirements of national standards. Therefore, after the electronic lock is added to the existing technology, it may occur that the customer needs to use the car temporarily during the charging process. It cannot be unlocked after receiving the command to stop charging, and the violent operation of the customer will cause the charging device to malfu...
