Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present invention. It should be understood that the drawings and the embodiments of the present invention are illustrative only and are not intended to limit the scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, and in the above-described drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For a clear understanding of the technical solutions of the present application, a detailed description of the prior art solutions is first provided.
In order to improve the cruising ability of the electric automobile, the SOFC is installed on the electric automobile, and the fuel cell is used as a range extender to charge the power cell, or the SOFC and the power cell together provide energy supply for driving the vehicle, so that the cruising ability of the electric automobile is improved.
In the prior art, when the start of the SOFC is controlled, the start of the SOFC is generally controlled by the VCU after the start of the vehicle. Since the start time of the SOFC is long, generally about one hour, if the SOFC is not used for a long time, it takes a longer time, and therefore, it is not possible to complete charging of the power battery before the vehicle enters the normal driving mode or to supply energy to the vehicle in driving together with the power battery after the vehicle enters the normal driving mode, which leads to poor cruising ability of the electric vehicle.
Therefore, the inventor finds that the remote one-key starting function of the SOFC can be realized by matching a remote control platform and a vehicle-mounted terminal on the basis of a whole vehicle control device of the electric vehicle. I.e. to control the SOFC to enter a remote start mode. Optionally, a client of the remote control platform may be loaded on the user terminal, and when the user needs a vehicle, the client sends a start request to the vehicle-mounted terminal, and the vehicle-mounted terminal sends a start signal to the VCU. The VCU receives a starting signal sent by the vehicle-mounted terminal; determining the receiving condition of the remote start judging signal according to the starting signal; and if the remote starting condition is determined to be met according to the receiving condition of the remote starting judging signal, controlling the SOFC to enter a remote starting mode so as to control the SOFC to start and charge the power battery. The SOFC can be controlled to be started before the vehicle is started so as to ensure that the SOFC is successfully started or the power battery is charged before the vehicle enters a normal driving mode, so that the SOFC and the power battery can jointly provide energy supply for vehicle driving after the vehicle enters the normal driving mode, and the cruising ability of the electric automobile is improved.

The fuel cell control method provided by the present embodiment includes the following steps.
Step 201, receiving a starting signal sent by the vehicle-mounted terminal.
Specifically, in this embodiment, when the user knows that the power battery SOC is low and needs to be charged or the demand of the utility vehicle is met, the user terminal may click a start icon on the client of the remote control platform loaded on the user terminal to control the remote control platform to send a start request to the vehicle-mounted terminal, the vehicle-mounted terminal generates a start instruction after receiving the start request, and sends a start signal to the vehicle control device, and the vehicle control device may receive the start signal.
Step 202, determining the receiving condition of the remote start judging signal according to the start signal.

Therefore, if it is determined that the key power-on signal is not received and the wake-up signal is received, it is determined that the remote start condition is satisfied. If the key power-on signal is determined to be received, determining that the normal driving condition is met, and determining that the remote starting condition is not met; if the wake-up signal is not received, the whole vehicle control device is not activated, and the fact that the remote starting condition is not met is determined. Therefore, if it is determined that the key power-on signal is received and/or the wake-up signal is not received, it is determined that the remote start condition is not satisfied.
And step 204, controlling the fuel cell to enter a remote starting mode.
Specifically, in this embodiment, if it is determined that the remote start condition is satisfied, the vehicle control device sends a remote start instruction to the fuel cell control system, and the fuel cell control system controls the SOFC to enter the remote start mode.
Step 205, determining whether the reference condition for starting the fuel cell is satisfied, if yes, executing step 206, otherwise executing step 207.
In this embodiment, after the fuel cell is controlled to enter the remote start mode, it is necessary to determine whether a reference condition for starting the fuel cell is satisfied.
Specifically, the judgment as to whether or not the reference condition for the start-up of the fuel cell is satisfied includes: judging whether the SOC of the power battery is not higher than an upper limit value; judging whether the SOFC manual switch is effective or not; judging whether the high-pressure state of the whole vehicle is normal or not; judging whether the whole vehicle is in a parking power generation, driving or remote starting mode; judging whether the residual electric quantity of the power battery is larger than the electric quantity required to be consumed in the SOFC starting process; judging whether the DCDC working state of the fuel cell is normal or not; and determines whether a shutdown command has not been received. If the SOC of the power battery is not higher than the upper limit value, the SOFC manual switch is effective, the high-voltage state of the whole vehicle is normal, the whole vehicle is in a parking power generation, driving or remote starting mode, the residual electric quantity of the power battery is larger than the electric quantity required to be consumed in the starting process of the SOFC, the DCDC working state of the fuel battery is normal, and a shutdown instruction is not received, the starting reference condition of the fuel battery is determined to be met, and otherwise, the starting reference condition of the fuel battery is determined not to be met.

And 2083, if the efficiency inflection point power is determined not to meet the adjustment condition, charging the power battery according to the efficiency inflection point power.
In this embodiment, if it is determined that the efficiency inflection point power does not satisfy the adjustment condition, the determined efficiency inflection point power may be directly used to charge the power battery.
In this embodiment, if the efficiency inflection point power is less than or equal to the power generation power limit of the fuel cell, it is determined that the efficiency inflection point power does not satisfy the adjustment condition, and the efficiency inflection point power is determined as the power required by the fuel cell to charge the power cell.
Step 209, if the key power-on signal is monitored and received, controlling the fuel cell to switch from the remote start mode to the normal driving mode, and controlling the fuel cell to operate according to the normal driving mode.
