  "textContent": "The present disclosure relates to a charging device. By providing a charge-enabled pin and an engage-enabled pin with different lengths in the charging interface of the charging device, the engage-enabled pin is firstly in contact with a battery when charging. At this time, a charging management circuit controls an LLC half-bridge resonant power supply to soft start. A third end of the charging management circuit outputs a signal to drive a first switch to be turned on, and the output end of the LLC half-bridge resonant power supply charges the battery, and charging soft start and zero-voltage connection are achieved. During the unplugging process, the charge-enabled pin is firstly removed from the battery, and zero-current disconnection can be achieved when unplugging the other pins of the charging interface.",
