A first embodiment of the present invention provides a control method for a fuel cell vehicle power system, as shown in fig. 1, including:

and S103, if the running power is greater than the set output power of the fuel cell of the whole vehicle and the current charge state is greater than the rated charge state of the super capacitor, controlling the super capacitor and the fuel cell to provide driving force and controlling the power cell of the whole vehicle to provide auxiliary electric energy.
In the present embodiment, the control method of the fuel cell automobile power system of the present embodiment is applied to a fuel cell power system. As shown in fig. 2, the power system of the fuel cell includes: a power battery 201, a Fuel cell 202, a Super capacitor 203, a bus bar 204, a Motor controller mcu (Motor Control unit)205, a driving Motor (Motor)206, a vehicle controller vcu (vehicle Control unit)207, and a Fuel cell-Super capacitors controller FCSC (Fuel cell-Super capacitors Control unit) 208. The FCSC208 is a controller for coordinating and controlling the fuel cell 202 and the super capacitor 203, so as to implement simplified and related control of the super capacitor 203 and the fuel cell 202 without modifying the vehicle control unit VCU 207. Both the super capacitor 203 and the fuel cell 202 are connected with a power distribution unit 209 of the power cell 201 through a bus bar 204, wherein the bus bar 204 is used for combining the fuel cell 202 and the super capacitor 203 to form double energy source supply, and the power distribution unit is used for coordinating the energy supply among the power cell 201, the fuel cell 202 and the super capacitor 203. One end of the motor controller MCU205 is connected with a power distribution power supply, and the other end is connected with the driving motor 206. Both the fuel cell 202 and the supercapacitor 203 are connected to a fuel cell-supercapacitor controller FCSC208, wherein the fuel cell-supercapacitor controller FCSC208 is used to control the fuel cell 202 and the supercapacitor 203. The motor controller MCU205 and the FCSC208 are both connected to the vehicle controller VCU 207.
It should be noted that the power battery 201, the fuel battery 202 and the super capacitor 203 of the present embodiment all refer to related components of a power battery, related components of a fuel battery and related components of a super capacitor in practical application of a fuel cell automobile. For example, the relevant components of the fuel cell in the practical application of the fuel cell automobile include a fuel cell body, a DC/DC (Direct Current converter) of the fuel cell body, and a fuel cell controller fccu (fuel cell control unit), which are collectively referred to as the fuel cell 202 in the present embodiment.
The power system is installed on the fuel cell automobile, and the specific installation position is set according to actual requirements. For example, as shown in fig. 3, a fuel cell 202 and a drive motor 206 of the power system are installed in a front compartment of a fuel cell automobile, a power cell 201 is installed below a front seat of the fuel cell automobile, and a supercapacitor 203 and a hydrogen storage tank of the fuel cell 202 are installed in a trunk of the fuel cell automobile.
The following describes in detail, with reference to fig. 1, specific implementation steps of the control method for the fuel cell vehicle power system provided in this embodiment:
firstly, step S101 is executed, and in the driving process of the entire vehicle, driving parameters of the entire vehicle are acquired, wherein the driving parameters include driving power of the entire vehicle and a current charge state of a super capacitor of the entire vehicle.
Specifically, in the running process of the whole vehicle, the running parameters of the whole vehicle are obtained according to the current voltage and current of the whole vehicle, and the running parameters comprise the running power, the running power increase rate, and the current charge state and the running state of a super capacitor of the whole vehicle. The driving power is driving power required by the whole vehicle in the driving process, for example, the whole vehicle needs to reach a vehicle speed of 80km/h, and the driving power corresponding to the vehicle speed is the driving power. The travel power increase rate is an increase rate of travel power.
Next, step S102 is executed to determine the running parameters. Then, step S103 is executed, if the driving power is greater than the set output power of the fuel cell of the entire vehicle and the current state of charge is greater than the rated state of charge of the super capacitor, the super capacitor and the fuel cell are controlled to provide driving force, and the power cell of the entire vehicle is controlled to provide auxiliary electric energy.
Specifically, after the driving parameters are judged, if the driving power is greater than the set output power of the fuel cell of the whole vehicle, and the current state of charge is greater than the rated state of charge of the super capacitor, which indicates that the driving force provided by the fuel cell cannot meet the actual driving force required by the whole vehicle, and the electric quantity of the super capacitor is enough, the super capacitor and the fuel cell are controlled to provide the driving force, and the power cell of the whole vehicle is controlled to provide auxiliary electric energy, namely the super capacitor is controlled to discharge, so that the super torch preferentially provides the driving force, then the fuel cell is controlled to supplement the driving force, and the power cell is controlled to provide the auxiliary electric energy for the whole vehicle, so as to meet the actual driving force required by the whole vehicle.
Here, it should be noted that after the super capacitor and the fuel cell are controlled to provide the driving force, the actual driving force required by the whole vehicle is still not met, and then the power cell is controlled to provide the auxiliary electric energy for the whole vehicle so as to meet the actual driving force required by the whole vehicle. After the super capacitor and the fuel cell are controlled to provide driving force, the actual driving force required by the whole vehicle is met, and the power cell is not required to be controlled to provide auxiliary electric energy for the whole vehicle. Under the conditions that the running power is larger than the set output power of a fuel cell of the whole vehicle and the current state of charge is larger than the rated state of charge of the super capacitor, the priority of the driving force provided by the super capacitor is larger than the priority of the driving force provided by the fuel cell, and the priority of the driving force provided by the fuel cell is larger than the priority of the driving force provided by the power cell.
In this embodiment, the set output power of the fuel cell and the rated state of charge of the super capacitor can be set according to actual requirements, the set output power of the fuel cell is generally the minimum output power of the fuel cell, and the rated state of charge of the super capacitor is generally the minimum state of charge of the super capacitor.
In the embodiment, the super capacitor is introduced into the power system of the fuel cell automobile, so that the fuel cell, the power cell and the super capacitor can all provide driving force for the whole automobile. In addition, the embodiment also realizes a control strategy among the fuel cell, the power cell and the super capacitor, so that the fuel cell, the power cell and the super capacitor provide driving force for the whole vehicle under different conditions, a power system of the fuel cell vehicle and the management of the energy of the whole vehicle are optimized, the power performance and the control efficiency of the fuel cell vehicle are improved, the service life of the power system is prolonged, and the response capability of the fuel cell vehicle is improved.
After the driving parameters are judged, if the driving power is greater than the set output power, and the current state of charge of the super capacitor is not greater than the rated state of charge of the super capacitor, the driving force provided by the fuel cell cannot meet the actual driving force required by the whole vehicle, and the electric quantity of the super capacitor is insufficient, the fuel cell and the power cell are controlled to provide the driving force, and the super capacitor is controlled to be in a standby state.
After the driving parameters are judged, if the driving power is not greater than the set output power, the driving force provided by the fuel cell can meet the actual driving force required by the whole vehicle, and the electric quantity of the super capacitor is insufficient, the fuel cell is controlled to provide the driving force, and the super capacitor and the power battery are controlled to be in a standby state.
After the driving parameters are judged, if the increase rate of the driving power is not greater than the increase rate of the output power of the fuel cell and the current charge state of the super capacitor is not greater than the rated charge state of the super capacitor, the output power of the fuel cell not only meets the actual power required by the whole vehicle, but also has redundant output power, and the fuel cell is controlled to charge the super capacitor. Wherein, the increasing rate of the output power of the fuel cell is set according to the actual demand, for example, the increasing rate of the output power of the fuel cell is 400W of the increasing rate of the output power per second.
After the driving parameters are judged, if the driving state is a braking state or a deceleration state, the super capacitor is controlled to recover energy, and the power battery is controlled to recover energy until the current charge state of the super capacitor meets the set charging condition of the super capacitor. The set charging condition of the super capacitor is that the current state of charge of the super capacitor is not less than the maximum state of charge of the super capacitor, and the maximum state of charge of the super capacitor is set according to actual requirements and is generally set to 95%.
In the process of controlling the power battery to recover energy, if the state of charge of the power battery is greater than the set state of charge of the power battery, the energy recovery of the whole vehicle is determined to be finished, and notification information is output. The set state of charge is the maximum state of charge of the power electric vehicle, and can be set according to actual requirements.
In the embodiment, when the whole vehicle is in a braking state or a deceleration state, the super capacitor is preferentially used for energy recovery. Under the condition that the charge state of the super capacitor is not less than the maximum charge state of the super capacitor, the power battery is controlled to recover energy, the service life of the power battery is prolonged, and the cruising ability of the whole vehicle is improved.
One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:
in this embodiment, in the driving process of the entire vehicle, driving parameters of the entire vehicle are obtained, where the driving parameters include driving power of the entire vehicle and a current state of charge of a super capacitor of the entire vehicle. The super capacitor is introduced into a power system of the fuel cell automobile, and the current charge state of the super capacitor of the whole automobile needs to be monitored in real time so as to control different energy sources of the whole automobile, improve the control efficiency of the whole automobile, optimize the power system of the fuel cell automobile and manage the energy of the whole automobile. Next, the driving parameters are determined.
And if the running power is greater than the set output power of the fuel cell of the whole vehicle and the current charge state is greater than the rated charge state of the super capacitor, controlling the super capacitor and the fuel cell to provide driving force and controlling the power cell of the whole vehicle to provide auxiliary electric energy. Here, the present embodiment implements a control strategy for the fuel cell, the power cell and the super capacitor, so that the fuel cell, the power cell and the super capacitor provide driving force for the entire vehicle under different conditions, optimize the power system of the fuel cell vehicle and manage the energy of the entire vehicle, improve the power performance and the control efficiency of the fuel cell vehicle, prolong the life of the power system, and improve the response capability of the fuel cell vehicle.
