Problems solved by technology

[0002] With the development of new energy vehicles, more and more new energy vehicles have functions such as remote wake-up and remote start-up of air conditioners. The power of electrical appliances is generally too high, and because of the fuel cell system, the capacity of the power battery is bound to become smaller and smaller. At this time, if the vehicle is started remotely, it is bound to consume a lot of power of the power battery

Embodiment 1

[0033] like figure 1 As shown, a control method of the remote start fuel cell system in this embodiment is shown, the control method can realize the remote start fuel cell system is turned on and off at the same time as the remote start of the vehicle, through the vehicle T-BOX, vehicle control The controller VUC sends the start command and the close command to the fuel cell system, and the power battery of the vehicle is replenished in time through the work of the fuel cell, which solves the problem of large power consumption of the power battery in the process of starting the car in the prior art. The control method for remotely starting the fuel cell system includes the following steps:

[0034] S1. When the mobile client detects that the SOC of the power battery of the vehicle is low, it sends a start-up command of the fuel cell system to the vehicle through the mobile client;

[0035] S2. After the mobile client sends the start-up command of the fuel cell system, the bac...

Embodiment 2

[0045] In this embodiment, on the basis of the first embodiment, improvements are made to speed up the charging speed of the fuel cell to the power battery.

[0046] Therefore, in this embodiment, after the fuel cell system receives the wake-up signal from the vehicle controller VUC, the fuel cell system starts up, and the fuel cell system adopts a circulating air control method, including the following steps:

[0047] After the fuel cell system is turned on, the anode gas and air are introduced into the anode and cathode of the fuel cell stack through the hydrogen path and the air path;

[0048] After the unreacted anode gas in the anode of the fuel cell stack passes through the water vapor separator, it is injected back into the hydrogen gas circuit for mixing, so as to increase the flow rate and concentration of the anode gas in the hydrogen gas circuit;

[0049] When the flow rate and concentration of the anode gas are detected to increase, the unreacted air in the cathode...

Abstract

The invention discloses a control method for remotely starting a fuel cell system, which comprises the following steps: S1, when detecting that the electric quantity SOC of a vehicle power battery is low, a starting work instruction is sent to a vehicle through a power client; S2, a background cloud receives a startup instruction and sends the startup instruction to the vehicle-mounted T-BOX; s3, after receiving the instruction, the vehicle-mounted T-BOX sends a fuel cell awakening signal to the vehicle control unit; S4, a vehicle control unit VUC awakens the fuel cell system; s5, the mobile client detects the state of the fuel cell system in real time; and S6, when it is detected that the electric quantity SOC of the power battery reaches an expected value, the mobile client can issue a fuel cell system shutdown instruction, and shutdown of the fuel cell system is realized. According to the control method, the remote starting fuel cell system can be started and stopped while the vehicle is remotely started, the power battery of the vehicle is supplemented with electric quantity in time through work of the fuel cell, and the problem that in the prior art, the electric quantity consumption of the power battery is large in the vehicle starting process is solved.

Description

technical field [0001] The invention relates to the technical field of fuel cell control, in particular to a control method for remotely starting a fuel cell system. Background technique [0002] With the development of new energy vehicles, more and more new energy vehicles have functions such as remote wake-up and remote start-up of air conditioners. The power of electrical appliances is generally too high, and because of the fuel cell system, the capacity of the power battery is bound to become smaller and smaller. At this time, if the vehicle is started remotely, the power of the power battery is bound to be greatly consumed. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a control method for remotely starting a fuel cell system. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a control method for remotely starting a fuel cell system, which is character...
