Abstract

The invention discloses an electronic lock detection circuit and an electric automobile. The electronic lock detection circuit comprises a drive power source, an electronic lock and a first detection circuit. The drive source comprises a first output end and a second output end, when the electronic lock needs to be opened, the first output end is a drive power positive electrode, and the second output end is a drive power negative electrode. The first end of the electronic lock is connected with the first output end, and the second end of the electronic lock is connected with the second output end. The input end of the first detection circuit is connected with the first output end, and the output end of the first detection circuit is connected with a micro control unit (MCU) of the electric automobile. When the MCU detects that voltage jump happens to the output end of the first detection circuit and the jump time of the voltage jump is in the preset time window, it is determined that the electronic lock is opened successfully, it can be accurately judged that the electronic lock is opened successfully, and safety use of a charging interface is ensured.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electronic lock detection circuit and the electric vehicle. Background technique [0002] With the development and popularization of new energy vehicles, the various requirements for electric vehicles are getting higher and higher. In charging applications where the charging current of electric vehicles is greater than 16A working current, the car charging socket must be equipped with an electronic locking mechanism. When the electronic When the lock is not reliably locked, the power supply equipment or electric vehicle should stop charging or cannot start charging, and the electronic lock should have a feedback signal to form a closed-loop control. [0003] At present, the diagnosis of the successful locking state of the electronic lock can be realized by detecting the feedback signal within a specified time; while the diagnosis of the successful unlocking state of the electr...
