The invention discloses a fuel cell low-temperature starting control method and device and a readable storage medium. The method comprises the steps that S1, the minimum power FCUPfcsmin of a fuel cell system, the maximum allowable continuous charging power BMSPPmaxchg of a power cell, the heating power BMSPheat of a heating film of the power cell and the real-time power VCUPaux of a whole vehicle auxiliary system are obtained in real time; s2, judging the FCUP (FCsminlt), and judging the FCUP; s3, judging whether FCUPfcsminlt is met or not, if yes, judging whether BMSPmaxchg + BMSPheat + VCUPaux-delta1 is met or not, if yes, executing the step S3, and if not, executing the step S4, and judging whether the conditions are met or not again until FCUPfcsminlt is met; after the BMS SPmaxchg + the BMS SPheat + the VCUPaux-delta1, the step S5 is executed again; s2, sending a fuel cell system start enable signal to the FCU and sending a battery thermal management electronic three-way valve start enable signal to the BMS; s3, a fuel cell non-starting enabling signal and a fuel cell PTC heater starting enabling signal are sent to the FCU, and a battery thermal management electronic three-way valve starting enabling signal is sent to the BMS; and S4, sending a fuel cell system starting enable signal to the FCU. According to the invention, during low-temperature starting, the damage to the power battery is small.
