the output connector, the charging socket, the energy storage protection circuit and the first detection device are integrated on a PCB.
7. A control method for an automobile emergency starting device, which is used for the automobile emergency starting device with the smart clamp according to any one of claims 1 to 6, and comprises the following steps:
s1, the first detection device sends a first detection signal to the first controller, and the first controller generates an energy storage device state signal according to the first detection signal;
the second detection device sends a second detection signal to a second controller, and the second controller generates a clamp state signal according to the second detection signal;
s2, the second controller sends a clamp state signal to the first controller, and the first controller judges the state of the smart clamp according to the energy storage device state signal and the clamp state signal;
s3, if the energy storage device state signal and the clamp state signal are both normal, the first controller judges that the smart clamp works normally, and the step S5 is executed;
if any one of the energy storage device status signal or the clamp status signal is abnormal, the step S4 is executed;
s4, if the clamp state signal is abnormal, checking and adjusting the clamp to enable the clamp to be connected into the automobile circuit in a correct posture, and then returning to the step S1;
if the state signal of the energy storage device is abnormal, the starting of the energy storage device is suspended, and the energy storage device is restarted when the state signal of the energy storage device is recovered to be normal;
and S5, starting the automobile.
8. The method as claimed in claim 7, wherein in step S4, when the energy storage device status signal is abnormal, the first controller sends an energy storage device suspension command to the second controller, and the second controller controls the energy storage device to suspend according to the energy storage device suspension command.
9. The method as claimed in claim 7, further comprising a switch connected between the clip and the energy storage device, wherein when the energy storage device status signal and the clip status signal are both normal, the first controller sends an opening command to the second controller, and the second controller opens the switch to enable the smart clip to work normally.
10. The method as claimed in claim 7, wherein the energy storage device status signal includes a remaining power signal and an operating temperature signal, and the clamp status signal includes a clamp connection status signal and a switch temperature signal.
