[0001] The invention relates to the technical field of emergency power supply, and in particular to an emergency power supply adaptive intelligent output circuit and a working process. Background Art
[0002] At present, the existing 12V / 24V universal emergency starting power supplies on the domestic market are relatively rigid in jump-starting recognition and still maintain manual recognition, that is, a manual button is pressed to output 12V or 24V for emergency starting of passenger cars or commercial vehicles. After the output clamp is clamped on the vehicle battery, the output of 12V starting voltage or 24V output voltage is confirmed by pressing a button.
[0003] However, the existing manual identification output voltage method has the following defects: it requires manual identification and button output, which is prone to errors and causes the 24V starting voltage to be output to the 12V passenger car battery, resulting in high voltage shock and burning the vehicle electrical appliances; forgetting to turn off the power after jump-charging the 24V and then jump-charging the 12V passenger car, resulting in high voltage shock and burning the vehicle electrical appliances. Summary of the invention

[0012] The working process of the emergency power supply adaptive intelligent output circuit includes the following steps:
[0013] Step 1: When the emergency power supply is turned off, the vehicle battery pack needs to be charged;
[0014] Step 2: The external output clamp P+ and the external output clamp P- of the emergency power supply are connected to the positive and negative poles of the vehicle battery pack respectively. The voltage of the vehicle battery pack forms a loop through the external output clamp P+, the external clamp intelligent wake-up module, and the external output clamp P-. At this time, the external clamp intelligent wake-up module is driven, and the external clamp intelligent wake-up module outputs the WAKEUPS INGE signal to the power module, and the power module wakes up.

[0016] Step 4: The MCU main control module detects the voltage of the vehicle battery pack through the external clamp voltage detection module. The MCU main control module determines whether the external output clamp P+ and the external output clamp P- are connected to a 12V passenger car or a 24V commercial vehicle according to the P+_AD signal sent by the external clamp voltage detection module;
[0017] Step 5: The MCU main control module detects the voltage of the vehicle battery pack based on the collected external clamp voltage detection module, and the MCU main control module displays the corresponding options on the human-machine interface module through the communication line and highlights them. After manual confirmation, the MCU main control module outputs the corresponding VOUT_CON signal to control the intelligent output switching module circuit to output the corresponding voltage.
