Abstract

The invention discloses an unlocking method for a charging electronic lock, and belongs to the field of charge control technology of new energy automobiles. The unlocking method for the charging electronic lock comprises the following steps: in the normal charging process, receiving a vehicle door-opening signal by a battery management system; when a charging gun is drawn, performing a charging electrifying process when the electronic lock is judged to be not in a locking state, and performing the charging electrifying process and driving the electronic lock to be retracted when the electroniclock is judged to be in the locking state. According to the unlocking method, a hardware switch or a software switch does not need to be added, the using cost of a user is reduced, an unlocking intention of a car owner can be identified intelligently, and the unlocking method is safe, simple and convenient, and unlocking is effective.

Description

technical field [0001] The invention belongs to the technical field of charging control of new energy vehicles, and in particular relates to a method for unlocking a charging electronic lock. Background technique [0002] At present, with the vigorous development of the new energy automobile industry, the capacity of battery packs is getting larger and larger, and the power of on-board chargers has been increasing. Most of the AC currents of single-phase chargers exceed 16A. The charging current needs to increase the electronic lock control. At present, many models use independent hardware switches to unlock, which is troublesome. The new design strategy can still recognize the owner's intention and unlock it on the basis of ensuring that no hardware switches are added. [0003] Invention patent application CN201611074506.2 discloses a control method and device for unlocking a car charging gun and a car charging gun. The method includes: receiving an unlocking signal inpu...
