摘要： A current detection circuit, a current leakage detection method and a charging system. The current detection circuit is capable of outputting an excitation signal to a first winding wound in a magnetic induction coil, and then determining whether there is leakage current in a first lead passing through the magnetic induction coil based on a feedback signal induced by the first winding and a reference signal, thereby determining whether there is an electric leakage while a charging device supplies electric energy to the outside, and providing a determination result to a control circuit. When there is an electric leakage, the control circuit can cut off a loop of the charging device for supplying electric energy to the outside in time, so that the charging device can stop supplying electric energy to the outside.

摘要： The present disclosure discloses a charging cover control method and device for an electric vehicle, and an electric vehicle. Whether there is a user approaching a charging cover is determined by detecting a biological signal; and after the biological signal is detected, an image of the front of the charging cover is collected and matched with a pre-stored set gesture image. When the gesture matching is successful, it means that the user currently performs a specific gesture action controlling the charging cover, and at this time, the charging cover is automatically controlled to be opened or closed, without the complicated steps such as manually operating the charging cover by the user, and the charging convenience is improved.
