The invention relates to the technical field of engineering machinery, and discloses a feedback current control device, a charger and an overhead working truck. The control device is arranged in the charger and comprises a first switch module; a second switch module; the capacitor is a capacitor in the charger; the control module is arranged in the charger and used for controlling the first switch module to conduct the power supply circuit where the first switch module is located in a one-way mode when the feedback current characterization parameter indicates that feedback current exists, the charging parameter of the capacitor is smaller than a preset charging parameter and the state parameter of the battery indicates that the lithium precipitation risk exists. And a circuit where the capacitor is located is conducted by controlling the second switch module, so that the feedback current is captured by the capacitor. According to the invention, the control device is arranged in the charger, and the capacitor and the control module in the charger are ingeniously adopted as parts of the control device, so that the risk of lithium precipitation can be avoided, the occupied space and cost additionally required by the control device can be saved, and the heat dissipation performance of the control device is good.
