摘要： The present disclosure provides a smart connection device, a jump starter and a battery clamp. The smart connection device includes a power connection terminal, a load connection terminal, a switch circuit, a controller, and a detection unit. The power connection terminal is configured to electrically couple with a power source, and the load connection terminal is electrically couple with an external load. The switch circuit is electrically coupled between the power connection terminal and the load connection terminal. The controller is configured to output a drive signal to the switch circuit to control the switch circuit to enter a conducting state. The detection unit detects a connection state between the load connection terminal and the external load, and outputs a corresponding control signal according to a detected connection state, wherein the control signal is not sent to the controller. The smart connection device can quickly respond to the reverse connection state of the external load and cut off the discharge of the power source to the external load in time, thereby improving detection speed and effectiveness of relevant protection functions.
