Abstract

The invention discloses a low temperature start-up method and system of a fuel cell vehicle, wherein the low-temperature start-up method comprises the following steps of: after receiving a remote start-up signal, judging whether the engine of the fuel cell vehicle is in a low-temperature state; if the engine is at low temperature, controlling a first battery to supply power to a heater in the fuelcell to raise the engine temperature, if it is detected that the engine is no longer at low temperature, controlling the first battery to stop supplying power to the heater and start the engine. Thus, before the engine starts at low temperature, the engine is preheated by an additional rechargeable battery, thereby reducing the energy loss of the power battery of the vehicle to the maximum extent, ensuring the cruising ability of the fuel cell vehicle, and effectively preventing pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a low-temperature starting method for a fuel cell vehicle and a low-temperature starting system for a fuel cell vehicle. Background technique [0002] With the development of automobiles, the sustainable development of the traditional automobile industry is facing the dual pressure of environmental pollution and energy shortage. [0003] In the related art, the above-mentioned pressure can be alleviated by fuel cell vehicles (for example, hydrogen fuel cell vehicles). However, when the fuel cell vehicle is in a low-temperature environment, the engine of the fuel cell vehicle needs to be heated for a long time to start the vehicle, and in this process, a large amount of energy of the power battery of the vehicle needs to be wasted , which greatly reduces the battery life of fuel cell vehicles and pollutes the environment. Contents of the invention [0004] The present inve...
