Smart connection device, jump starter, and battery clamp

A jump starter, comprising:

• a battery pack;
• and a smart connection device comprising:
• a power connection terminal electrically couple with the battery pack;
• a load connection terminal configured to electrically couple with an external load;
• a switch circuit comprising a switch element and a switch drive module, wherein the switch element is electrically coupled between the power connection terminal and the load connection terminal;
• the switch drive module is electrically coupled to the switch element and configured to turn on or turn off the switch element;
• and a reverse connection detection module electrically coupled to the load connection terminal, wherein the reverse connection detection module is configured to detect a connection state between the load connection terminal and the external load, and output a corresponding control signal according to a detected connection state;
• wherein the control signal is configured to switch operation states of the switch drive module, wherein the operation states of the switch drive module comprises an active state and a disable state;
• wherein the switch drive module is able to respond to a drive signal to turn on the switch element when the switch drive module is in the active state, thereby conducting an electrical connection between the battery pack and the external load, so as to realize the discharge of the battery pack to the external load;
• wherein the switch element is in an off state when the switch drive module is in the disable state, thereby disconnecting the electrical connection between the battery pack and the external load, so as to prevent the battery pack from discharging to the external load.

A battery clamp, comprising:

• a housing;
• a power input interface provided on the housing, wherein the power input interface is configured to electrically couple with an external power device, wherein the external power device comprises a battery pack;
• and a connection element;
• a smart connection device comprising:
• a power connection terminal electrically coupled to the power input interface, and electrically coupled to the battery pack of the external power device through the power input interface;
• a load connection terminal electrically coupled to one end of the connection element, wherein the other end of the connection element is configured to electrically couple with an external load;
• a switch circuit comprising a switch element and a switch drive module, wherein the switch element is electrically coupled between the power connection terminal and the load connection terminal;
• the switch drive module is electrically coupled to the switch element and configured to turn on or turn off the switch element;
• and a reverse connection detection module electrically coupled to the load connection terminal, wherein the reverse connection detection module is configured to detect a connection state between the load connection terminal and the external load, and output a corresponding control signal according to a detected connection state;
• wherein the control signal is configured to switch operation states of the switch drive module, wherein the operation states of the switch drive module comprises an active state and a disable state;
• wherein the switch drive module is able to respond to a drive signal to turn on the switch element when the switch drive module is in the active state, thereby conducting an electrical connection between the battery pack and the external load, so as to realize the discharge of the battery pack to the external load;
• wherein the switch element is in an off state when the switch drive module is in the disable state, thereby disconnecting the electrical connection between the battery pack and the external load, so as to prevent the battery pack from discharging to the external load.
