The invention relates to a thermal management controller energy discharge module, a power supply system and an automobile, the thermal management controller energy discharge module comprises a differential amplification circuit and an energy release circuit, the differential amplification circuit is used for detecting voltage fluctuation and generating a control signal, and the energy release circuit releases redundant energy according to the control signal; the differential amplification circuit comprises an operational amplifier U, capacitors C16 to C21, and resistors R8 to R12; the energy release circuit comprises an MOS tube Q3 and a resistor R13. When the MOS tube Q3 is conducted, redundant energy in the heat management controller power supply module is released through the resistor R13, and the ripple voltage of the P12VBLDCMOS is clamped within a controllable range. According to the invention, voltage fluctuation can be automatically detected and responded, and rapid release of energy is realized through intelligent control, so that a chip in the controller is protected from being influenced by the voltage fluctuation.
