Smart connection device, jump starter, and battery clamp

A jump starter, comprising:

• a housing;
• a battery assembly;
• and
• a smart connection device comprising:
• a power connection terminal electrically coupled with the battery assembly;
• a load connection terminal configured to electrically couple with an external load;
• a switch circuit electrically coupled between the power connection terminal and the load connection terminal;
• a controller configured to output a drive signal, wherein the drive signal is configured to conduct the switch circuit;
• a drive signal transmission module electrically coupled between the switch circuit and the controller, wherein the drive signal transmission module is configured to transmit the drive signal output by the controller to the switch circuit;
• and
• a reverse connection detection module electrically coupled to the load connection terminal and the drive signal transmission module respectively, wherein the reverse connection detection module is configured to output a first control signal when it detects that the external load is reversely coupled to the load connection terminal, wherein the first control signal is configured to control the drive signal transmission module to suspend the transmission of the drive signal, so that the switch circuit is kept in an off state, thereby disconnecting an electrical connection between the battery assembly and the external load, so as to prevent the battery assembly from providing a discharge output to the external load;
• wherein the battery assembly and at least a part of structures of the smart connection device are provided in the housing.
