Abstract: 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.
