The invention provides a CAN communication terminal resistor module of a hydrogen fuel electric vehicle, which comprises a processor and a CAN transceiver. The processor is bidirectionally and electrically connected with the CAN transceiver; the CANH end of the CAN transceiver is respectively connected with a PinA pin wire and a PinH pin wire; a first CANTERM interface and a CANH interface are formed; a first resistor R1 is arranged between the PinA pin wire and the first CANTERM interface; the CANL end of the CAN transceiver is connected with the PinL pin wire and the PinD pin wire to form aCANL interface and a second CANTERM interface, and a second resistor R2 is arranged between the PinD pin wire and the second CANTERM interface. The CAN communication terminal resistor module is simplein structure. The CAN communication terminal resistor module is suitable for a controller with a CAN communication interface, especially a new energy electric drive assembly. The CAN communication terminal resistor has great flexibility in arrangement of CAN network terminal resistors. The requirements that the whole vehicle has the terminal resistors and removes the terminal resistors can be meton the basis that internal hardware of the product is not changed through short circuit and disconnection of an external interface of the electric drive assembly.
