    摘要: The present application provides a hardware failure diagnosis method and apparatus for a DCDC conversion module, and a storage medium. The DCDC conversion module comprises: a first branch circuit and a second branch circuit which are connected in parallel. The hardware failure diagnosis method for the DCDC conversion module comprises: collecting currents and voltages of input ends and output ends of a first branch circuit and a second branch circuit; according to the currents and the voltages, determining whether a hardware failure occurs; physically turning off the branch circuit having the hardware failure; logically turning off the two branch circuits, and entering a temporary failure mode; and controlling, at least once, the first branch circuit and/or the second branch circuit to exit the temporary failure mode. According to the present application, the first branch circuit and the second branch circuit which are connected in parallel are provided on the DCDC conversion module, so that the other branch circuit without the hardware failure can exit from the temporary failure mode and normally maintain power output under the condition that one branch circuit has the hardware failure, and the driving safety of the whole vehicle is ensured.
