In the present invention, the control board 20 and the power board 30 are electrically connected through the pin header 80, and the first low voltage input terminal 21 and the second low voltage input terminal 22 are designed on the control board 20, so that the occurrence of abnormal control power signals and control failures caused by loose connectors can be effectively reduced. Control board 20 is used to control and collect temperature, voltage, current, and hardware status information of power board 30. The copper bar 60 is a flexible copper bar, is arranged on the power board 30, and is used for completing high-voltage connection between the super capacitor module 40 and the bidirectional DC module 50, and the flexible copper bar can effectively resist external pressure, has a certain damping effect and protects the safety of a high-voltage circuit.

Specifically, the working principle of the auxiliary energy two-in-one system is as follows: the first low-voltage input end 21 provides low-voltage power for the control panel 20 through the first low-voltage power socket 11 and the second low-voltage input end 22 through the second low-voltage power socket 12, the control panel 20 starts to work after receiving the low-voltage power, collects and controls the state of the power panel 30, when the control board 20 receives the upper high voltage command sent by the vehicle control unit VCU, the control board 20 starts to execute the auxiliary energy integrated two-in-one system pre-charging process, namely, the control board 20 controls the negative contactor to close, and then controls the pre-charging contactor 46 to close, so as to realize the current flowing through the first capacitor unit 41 and the second capacitor unit 42, through the inner MBD switch 13, the current flows through the pre-charging protector, passes through the pre-charging contactor 46 and the pre-charging resistor 47, passes through the positive electrode of the flexible copper bar 60, reaches the pre-charging capacitor 52, passes through the negative electrode and the negative electrode contactor of the flexible copper bar 60, and flows back to the second capacitor monomer 42 to form a complete power supply loop; when the pre-charging is finished, the control panel 20 controls the super capacitor anode contactor 45 to be attracted, and after waiting for 0.1s, the control panel 20 controls the pre-charging contactor 46 to be disconnected, so that the high-voltage function of the auxiliary energy integrated two-in-one system is finished.
After the high voltage is finished, when the control board 20 receives a discharging instruction sent by the vehicle control unit VCU, the control board 20 actively adjusts the output voltage of the boost circuit in the boost-buck module 51 according to the discharging power, so as to realize the function of discharging the external power of the auxiliary energy integrated two-in-one system.
After the high voltage is finished, when the control board 20 receives a charging instruction sent by the VCU of the vehicle control unit, the control board 20 actively adjusts the output voltage of the step-down circuit in the step-up/step-down module 51 according to the charging power, so as to realize the function of discharging the external power of the integrated two-in-one system of the auxiliary energy.
After the high voltage is finished, when the control board 20 receives a charging instruction sent by the vehicle control unit VCU, the control board 20 actively adjusts the output voltage of the boost circuit in the boost-buck module 51 according to the discharging power, so as to realize the charging function of the auxiliary energy integrated two-in-one system on the super capacitor.
After the high voltage is finished, when the control board 20 receives a charging instruction sent by the VCU of the vehicle control unit, the control board 20 actively adjusts the output voltage of the step-down circuit in the step-up/step-down module 51 according to the charging power, so as to realize the function of charging the super capacitor by the auxiliary energy integrated two-in-one system.
Whether the step-up/step-down module 51 performs step-up or step-down is determined by the charging/discharging state and the voltages of the high-voltage input end and the high-voltage output end of the step-up/step-down module 51; during charging, the input voltage of the high-voltage input end of the voltage boosting and reducing module 51 is higher than that of the high-voltage output end, the voltage boosting and reducing module 51 is adopted for boosting at the moment, the input voltage of the high-voltage input end of the voltage boosting and reducing module 51 is lower than that of the high-voltage output end, and the voltage reducing and reducing module 51 is adopted for reducing the voltage at the moment; during discharging, the high-voltage input end input voltage of the buck-boost module 51 is higher than the high-voltage output end, the buck-boost module 51 is adopted to reduce the voltage at the moment, the high-voltage input end input voltage of the buck-boost module 51 is lower than the high-voltage output end, and the buck-boost module 51 is adopted to boost the voltage at the moment.
