Abstract

The invention discloses a preheating control method and device for a plug-in fuel cell vehicle. The method comprises the steps that the travel time and a preheating demand are set through an APP; whether the automobile needs to be charged is detected; after the charging is completed or when the charging is not needed, the TBOX calculates the advanced preheating time; the TBOX awakening time is set, and the vehicle enters a sleep state after setting is completed; after the time is up, the TBOX is awakened, the VCU is awakened after the TBOX is awakened, the BMS\ FCU\ MCU\ DCDC&OBC is awakened by the VCU, and state monitoring is carried out; the OBC is started after completion of determination, electric quantity is provided for work of the PTC, and a power battery and a fuel cell system arepreheated; after preheating is completed, the vehicle enters a sleep state, and the vehicle is started by a user. The defect that an existing fuel cell vehicle cannot be started at a low temperature or waits for a long time to be started is overcome.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicles, in particular to a preheating control method and device for a plug-in fuel cell vehicle. Background technique [0002] Fuel cells and power batteries have the advantages of high energy conversion efficiency, environmental friendliness, and no noise, and have become the preferred power source to solve the problems of environmental pollution and energy depletion. [0003] There is a large amount of water inside the proton exchange membrane fuel cell when it is working, including the water generated by the reaction and the water used for humidification during the reaction. In the low temperature environment of the proton exchange membrane fuel cell, due to the freezing of liquid water inside the battery, it may make it difficult to start, prolong the start-up time, and damage the structure of the membrane cell. In order to ensure successful startup, the stack needs to be preheated. [0...
