It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 1, the present invention provides a comprehensive power supply method of a fuel cell and a power battery, the comprehensive power supply method comprising:
in step S11, according to the real-time energy demand, outputting electric energy through at least one power battery in the power battery pack;
in step S12, electric power is output to the power cell stack through the fuel cell while the at least one power cell outputs electric power.
In one embodiment, a power battery pack is provided that includes at least two power cells, the states of the power cells including any one or more of an output state, a standby state, and a charged state. The number of fuel cells is not limited. The power battery pack has the advantages that a part of power batteries of the power battery pack output electric energy and the other part of power batteries are charged, so that the technical effects of charging and discharging the whole power battery pack can be realized. In the comprehensive energy supply method of the fuel cell and the power battery pack, the power battery pack is responsible for directly outputting electric energy, and the fuel cell is responsible for inputting electric energy to the power battery pack.
The technical scheme of the embodiment can be applied to a fuel cell vehicle, wherein a power system of the fuel cell vehicle comprises a fuel cell system assembly, a power cell system assembly, a super capacitor system assembly, a motor system assembly, a whole vehicle controller assembly, an electric door pedal assembly, a brake pedal assembly and the like, the specific connection relationship among the fuel cell system assembly, the power cell system assembly and the motor system assembly is shown in fig. 6, a solid line connecting line in fig. 6 is an energy line, and a dotted line connecting line is a signal line.
The fuel cell system assembly includes a fuel cell system, a fuel cell system controller, and the like. The fuel cell system operates only at a rated operating point, and thus the hydrogen circulation system of the fuel cell system can be simplified. Furthermore, electromagnetic stop valves, ejectors, water separator and the like can be simplified, and meanwhile, the original complex control logic of the hydrogen circulation system can be simplified into switch control. The fuel cell system controller controls the orderly operation of the components of the fuel cell system and simultaneously receives instructions and parameters from the upstream and downstream controllers and the system.
The power battery system assembly comprises a power battery pack, a direct current chopper (DC/DC) and a power battery system controller. The power batteries in the power battery pack are used for alternating cycle of charging and discharging. The direct current chopper (DC/DC) can realize functions of boosting, reducing voltage, stabilizing voltage and bidirectional current flow. The power battery system controller is used for controlling the orderly operation of the parts of the system and receiving the instructions and parameters from the upstream and downstream controllers and the system.
The super capacitor system comprises a super capacitor system and a super capacitor system controller. The super capacitor system is used for the working condition that the output power of the power battery pack is insufficient when the fuel automobile runs at high power of the motor. The super capacitor system controller is used for controlling the orderly operation of the system parts and simultaneously receiving instructions and parameters from the upstream and downstream controllers and the system.
The motor system assembly comprises an automobile motor, a motor system controller and the like. The automobile motor converts the electric energy transmitted from the upstream into rotational kinetic energy to drive the automobile to advance or retreat, and meanwhile, a power recovery device is arranged in the motor. The motor system controller controls the motor to act and simultaneously receives instructions and parameters from the upstream and downstream controllers and the system.
The whole vehicle controller assembly is used for receiving all instructions and parameters of the whole vehicle and sending out corresponding instructions.
The electric pedal assembly enables a driver to operate a pedal of the whole vehicle to advance, and can send energy demands to a whole vehicle controller system.
The brake pedal assembly enables a driver to operate a pedal for decelerating or stopping the whole vehicle, and can send braking demands to the whole vehicle controller system.
In the technical scheme, a fuel cell system assembly, a power cell system assembly and a motor system assembly in the power system are in a series mode. The power battery system assembly comprises a power battery pack and at least two power batteries, and the power battery pack is used for realizing the function of charging and discharging the power battery pack.
After the fuel cell automobile is started or accelerated, a driver presses an electric valve pedal, and the electric valve pedal assembly generates corresponding electric signals to be input to the whole automobile controller assembly. The whole vehicle controller assembly calculates and generates electric energy which needs to be provided for the motor by the power battery and transmits a demand signal to the power battery pack. After the power battery receives the signals, at least one power battery is selected through calculation, the signals are transmitted to a direct current chopper (DC/DC), and the corresponding relay switch is turned on to transmit the required electric energy to the motor. If the power battery system is smaller than the required power after calculation, the signal is returned to the whole vehicle controller, and the whole vehicle controller transmits the corresponding required signal to the super capacitor system controller. The super capacitor system controller analyzes and calculates the received demand signal, transmits the signal to a direct current chopper (DC/DC), turns on a corresponding relay switch, and provides electric energy for the motor together with the power battery pack. If the power of the super capacitor system is smaller than the required power after the calculation of the super capacitor system, a signal is returned to the whole vehicle controller, and the whole vehicle controller transmits a corresponding demand signal to the power battery system controller, so that the power battery pack is forced to be added with a new power battery to make up for the power defect.
When the electric quantity of any power battery outputting electric energy is lower than a preset charging threshold value, at least one power battery in a standby state is used for replacing or improving the output power of at least one power battery in an output state.
In the process that the power systems such as the fuel cell vehicle slides and brakes do not have electric energy output, the rotation of wheels drives a motor to rotate, the motor is converted into a generator to generate electric energy, an electric signal is transmitted to a whole vehicle controller through a motor system controller by the motor, a demand signal is transmitted to the power cell system controller after calculation by the whole vehicle controller, a power battery pack which needs to store and recycle electric energy is obtained through calculation, the demand signal is sent to DC/DC, the DC/DC is controlled to be connected with a corresponding relay switch, and then the electric energy recycled by the motor is reversely input to the corresponding power battery pack through the DC/DC.
In the normal running process of the fuel electric vehicle, a System On Chip (SOC) of the power battery pack can be reduced to a corresponding threshold value, at the moment, the power battery System controller can transmit a corresponding signal to the whole vehicle controller, and the whole vehicle controller sends a start-up 'charge-while-discharge' mode instruction to the power battery controller and the fuel battery System controller through calculating the signal. Further, after receiving the signal, the power battery system controller analyzes and requests a part of power batteries of the power battery pack to output electric energy, and the other part of power batteries to input electric energy. The power battery system controller sends an instruction to the DC/DC, and requires that the relay switch of one part of the power batteries in the power battery pack is in an on state at the same time, and after the other part of the power batteries are connected in a stable manner, the relay switch corresponding to one part of the power batteries is disconnected, and the charging relay switch corresponding to the other part of the power batteries is connected at the same time. After receiving the signal, the fuel cell system controller starts the fuel cell system to charge a part of the power cells which are not full of electricity. When the power battery is charged to a preset high-power threshold value, the power battery system transmits signals to the whole vehicle controller, and the whole vehicle controller transmits signals for switching off corresponding relay switches to the fuel battery system controller and the power battery controller. The electric valve pedal is directly connected with the power battery system, and the electric valve pedal is not directly connected with the fuel battery system. The fuel cell is kept to output electric energy under a preset working condition point, namely the fuel cell system is always in a stable charging rated working condition, and fluctuation of the rated working condition is small. Because the working condition of the fuel cell system is single, complex software and hardware calibration is not needed in the product development process, and the hardware structure of the hydrogen circulation system is simple.
And when the real-time energy requirement is lower than the preset full-power threshold, outputting electric energy to at least one power battery which is not full of power through the fuel battery until all the power batteries reach the preset high-power threshold. That is, when the vehicle is driven to end and stop, the real-time energy requirement of the whole vehicle is low, and the real-time energy requirement is usually lower than a preset full-power threshold. Under the condition that the real-time energy requirement is lower than a preset full-power threshold, the power battery system controller and the super capacitor system controller send out a power-supplementing requirement signal to the whole vehicle controller assembly, the whole vehicle controller assembly sends out permission to the power battery system controller and the super capacitor system controller after calculation and specifies a power-supplementing sequence, the power battery system controller and the super capacitor system controller are sequentially connected with corresponding relay switches, the corresponding relay switches are automatically disconnected after the power-supplementing is finished, and the fuel battery system is automatically powered off and stopped.
According to the technical scheme, the fuel cell outputs electric energy to the power battery pack, in the running process of the fuel cell vehicle, one part of the power cells output electric energy to drive the fuel cell vehicle, the other part of the power cells are charged through the fuel cells, and the fuel cells can keep a single working condition in the whole process, so that a hydrogen circulation system is simplified. Furthermore, the architecture of a hydrogen circulation system in the fuel cell system is simplified, and the hardware development cost and the software development cost are reduced; meanwhile, the calibration period of a hydrogen circulation system part in the fuel cell system is reduced, and the development cost and the development period of the fuel cell system are reduced.
In one embodiment, as shown in FIG. 2, the method further comprises the following steps S21-S23:
outputting electric energy by increasing at least one power cell when the real-time energy demand increases in step S21; or (b)
In step S22, when the real-time energy demand increases, the output power of at least one power battery in an output state is increased; or (b)
In step S23, when the real-time energy demand increases, electric energy is output by increasing at least one power battery and power is output by increasing at least one power battery in an output state.
In one embodiment, the real-time energy demand may be increased when the fuel cell vehicle is accelerating, climbing a hill, or turning on an in-vehicle electrical (e.g., air conditioning). The specific strategy for improving the output power is adjusted according to the number of the batteries in the power battery pack in the standby state. If the number of the power batteries in the standby state in the power battery pack is too small, the output power of the whole power battery pack is increased by increasing the output power of at least one power battery in the output state; if more power batteries are in standby state in the power battery pack, the output power of the whole power battery pack is improved by increasing the output electric energy of at least one power battery; between too few and too many power cells in the power battery pack in a standby state, the system can dynamically select a mode of simultaneously increasing the output electric energy of at least one power cell and increasing the output power of at least one power cell in an output state to increase the output power of the whole power battery pack.
In one embodiment, as shown in FIG. 3, the method further comprises the following steps S31-S32:
in step S31, when the real-time energy requirement reaches a preset high power threshold, power is supplied by using a super capacitor;
in step S32, when the super capacitor stops supplying power, the super capacitor is charged by using at least one power battery in a standby state.
In one embodiment, the technical solution using super-capacitors has a better power supply speed and strength when the real-time energy demand of the fuel cell vehicle reaches or exceeds a preset high power threshold for a short period of time, compared to the power supply using the strategy described above in connection with the power battery, which has the disadvantage that the power supply can only be performed for a short period of time. In a preferred embodiment, the shorter period of time is a period of time of no more than one hundred seconds. After the super capacitor is discharged, the super capacitor system controller controls the DC/DC to be connected with a corresponding charging relay switch of the super capacitor system, and sends a power supplementing demand to the whole vehicle controller, a power battery system controller transmits a power supplementing demand signal of the whole vehicle controller to the super capacitor system to the power battery system controller, the power battery system controller controls the DC/DC to be connected with the relay switch for charging the super capacitor system, so that power is supplemented to the super capacitor system, and the corresponding relay switch is disconnected after the power supplementing is finished.
