Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Embodiment of fuel cell vehicle starting method:

[0026] This embodiment provides a method for starting a fuel cell vehicle, and its corresponding control flow chart is as follows figure 1 shown, including the following steps:

[0027] (1) Detect the temperature of the power battery and the temperature of the fuel cell, and judge the temperature of the power battery and the temperature of the fuel cell.

[0028] Among them, in order to detect the temperature of the power battery and the temperature of the fuel cell, a temperature sensor is set for the power battery and the fuel cell, and the temperature sensor collects the temperature information of the power battery and the fuel cell, and sends the temperature information through...

Abstract

The invention relates to a fuel cell vehicle and a starting method and a device thereof. The method comprises the following steps of: detecting the temperature of a power battery and a fuel battery, detecting the state of charge of the power battery if the temperature of the power battery and the temperature of the fuel battery are both lower than corresponding set target temperature values, and outputting an instruction for controlling a vehicle to heat the power battery and the fuel battery while driving if the state of charge of the power battery is greater than a first preset value; outputting an instruction of firstly heating the power battery and the fuel battery and then controlling driving after the power battery and the fuel battery are heated if the state of charge of the power battery is less than or equal to the first preset value and greater than a second preset value; and outputting an instruction of charging the power battery if the state of charge of the power battery is less than or equal to the second preset value. The situation of the electric quantity of the power battery is fully considered, temperature rising operation or driving operation of the power batteryand the fuel battery can be effectively achieved, and the vehicle control reliability is improved.

Description

technical field [0001] The invention relates to a fuel cell vehicle and its starting method and device, belonging to the technical field of new energy vehicles. Background technique [0002] At present, there are certain problems in the environmental adaptability of the fuel cell system and the power battery system. If the fuel cell is in a low temperature state, the fuel cell cannot be started; if the power battery is in a low temperature state, the output power efficiency of the power battery is extremely low and The power battery cannot be charged. Therefore, in general, when the vehicle is started, it is necessary to detect the temperature of the fuel cell and the power battery. After rising, drive again. However, in this process, the power condition of the power battery and the driver's feeling are not considered. If the power battery power is extremely low, the heating operation of the power battery and the fuel cell cannot be completed; or even if the heating operat...
