Detailed Description
In an embodiment of the present invention, the FCV includes an energy storage battery and a fuel cell, the energy storage battery may be selected from a lithium battery, a nickel-cadmium battery, a lead-acid battery, a nickel-hydrogen battery, a lithium iron phosphate battery, etc., and the fuel used in the fuel cell may be high purity hydrogen, high hydrogen content reformed gas obtained by reforming hydrogen-containing fuel, methanol, etc.
In an embodiment of the invention, the various components of the FCV have electronic controller units (Electronic Control Unit, ECU) for corresponding operations and controls, respectively. For example, an ECU for electric power control (electric power control ECU), an ECU for controlling and managing a fuel cell (fuel cell ECU), and an ECU for controlling and managing an energy storage battery (energy storage battery ECU).
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
As shown in fig. 1, a method 100 of charging an energy storage battery of a fuel cell vehicle includes: step one, receiving an input signal of a manual request for charging an energy storage battery; step two, inquiring the SOC real-time value of the energy storage battery; and thirdly, judging whether the SOC real-time value is lower than an SOC threshold value, if so, selectively sending a charging signal needing to be charged with expected power to a fuel cell of the fuel cell automobile, wherein the expected power is suitable for enabling the SOC real-time value of the energy storage battery not to be lower than the SOC threshold value, and the charging signal is suitable for enabling the fuel cell to generate output power provided to the energy storage battery.
In the execution of step one, the user may request manual charging of the energy storage battery based on the specific situation in which the vehicle is running. For example, in a specific driving state such as FCV start, acceleration or climbing, in addition to the fuel cell providing power for a user to drive the automobile, the energy storage battery also needs to simultaneously provide corresponding power, thereby improving the driving performance of the FCV.
Specifically, the user can learn the specific running state of the vehicle running (such as FCV start, acceleration or climbing) or the information that the SOC real-time value of the energy storage battery is always lower than the SOC threshold value according to the judgment of the user or the prompt information provided by the display screen, voice, sound or vibration and other devices in the vehicle, and the need of charging the energy storage battery is determined.
The user then inputs an input signal to the vehicle (e.g., power control ECU) requesting that the energy storage battery be charged, either through a control in the vehicle or through voice.
The control can be a physical control on the operation panel, and a user can provide an input signal for the electric control ECU by touching, pressing, pulling out, rotating or moving the physical control; the control can also be a virtual control on the display screen, and the user can touch, press, move or rotate the virtual control to provide input signals to the automobile; the user may also provide input signals to the car by voice input means (e.g., voice "charge the energy storage battery").
In the execution of step two, based on the received input signal requesting charging of the energy storage battery, the power control ECU transmits a check signal to the energy storage battery ECU, and the energy storage battery ECU responds to the check signal and feeds back the SOC real-time value of the energy storage battery to the power control ECU.
In the execution of step three, the SOC real-time value is compared with the SOC threshold value.
In the embodiment shown in fig. 2, the FCV is in a specific driving state, and initially, the real-time value of the SOC is within a preset range, but continuously falls below the SOC threshold value during continuous climbing. In this process, the SOC real-time value is compared with the SOC threshold value, and when the former is lower than the latter, the fuel cell is required to charge the energy storage battery.
The value range of SOC may be set to be greater than or equal to 0 and less than or equal to 100%, with an SOC value equal to 0 indicating that the energy storage battery is not storing power and an SOC value equal to 100% indicating that the energy storage battery is fully charged; the scale may be equally divided between 0 and 100% SOC so that the proportion of the energy storage battery storing power may be measured in particular, for example 30%, 50% and 70% SOC representing 30%, 50% and 70% of the power stored by the energy storage battery when it is fully charged, respectively.
The SOC threshold is used to determine whether the SOC real-time value is low, so that it can be determined whether the current state of charge of the energy storage battery is sufficient to provide additional power to improve the driving performance of the FCV in a specific driving state such as start-up, acceleration or climbing. For example, the SOC threshold is selected from the range of 30% to 50% of the power when the energy storage battery is fully charged.
The electric power control ECU judges whether the SOC real-time value is lower than the SOC threshold value, if so, selectively transmits a charging signal requiring the desired power to be charged to the fuel cell ECU, and if not, ends the operation flow without selectively transmitting the charging signal requiring the desired power to be charged to the fuel cell ECU.
Selectively sending a charge signal indicative of the desired power to be charged to the fuel cell ECU, the power control ECU also being required to determine the operating state of the fuel cell, e.g., whether the fuel cell is in a normal operating state, and whether the fuel cell is capable of generating an amount of power of the desired power; next, the electric power control ECU determines whether to transmit a charging signal that requires charging of the expected power to the fuel cell ECU based on these operating states.
Specifically, the electric power control ECU may send a second query signal to the fuel cell ECU that queries the fuel cell state including a state as to whether the fuel cell is in a normal operating state and an amount of electricity that can generate the desired power; the fuel cell ECU transmits a status signal including information about whether the fuel cell is in a normal operation state and whether an amount of electricity of a desired power can be generated in response to the second query signal; the electric power control ECU receives the status signals transmitted by the fuel cell ECU, and determines whether the fuel cell is in a normal operation state and whether an amount of electricity of a desired power can be generated based on the status signals, if both are yes, transmits a charging signal requiring the desired power to be charged to the fuel cell ECU, and if at least one of the both is no, ends the operation flow without transmitting a charging signal requiring the desired power to be charged to the fuel cell ECU.
In the embodiment shown in fig. 3, the FCV is in a specific driving state, and when the SOC real-time value is lower than the SOC threshold value, the fuel cell continuously charges the energy storage battery, so that the real-time SOC of the energy storage battery continuously rises and exceeds the SOC threshold value to be within a preset range.
In some embodiments, the expected power is a first expected power that charges the SOC of the energy storage battery to a preset ratio, wherein the SOC preset ratio is not lower than the SOC threshold value.
Specifically, the user can provide information of the preset ratio of the SOC in the input signal by operating a control or inputting voice.
For example, the operating control itself may contain by default information to charge the energy storage battery to a preset proportion of SOC (e.g., 65%); the user can provide information of the preset SOC ratio to the automobile through a voice input mode (for example, voice "charge SOC of the energy storage battery to 65%"). Through operation control or voice input, the input signal for charging the energy storage battery comprises information of the preset ratio of the SOC.
For another example, a control may be provided having a plurality of gears corresponding to a plurality of different SOC preset ratios, respectively; a plurality of controls can also be provided, which respectively correspond to a plurality of different SOC preset ratios; different voice input modes (for example, voice of "charge SOC of the energy storage battery to 60%" "charge SOC of the energy storage battery to 65%" "charge SOC of the energy storage battery to 70%") can also be provided, which respectively correspond to a plurality of different SOC preset ratios. By placing the control in a specific gear, operating the specific control or inputting specific voice, the input signal for charging the energy storage battery includes information of a specific SOC preset ratio.
In other embodiments, the expected power is a second expected power, wherein the second expected power is adapted such that the SOC real-time value of the energy storage battery is not lower than the SOC threshold value.
Specifically, the input signal does not include information related to the expected power. When the electric power control ECU judges that the SOC real-time value is lower than the SOC threshold value, the electric power control ECU sends a first query signal of the electric quantity required by the energy storage battery to the energy storage battery ECU; the energy storage battery ECU sends a feedback signal of second expected power which needs to be charged based on the first query signal; the power control ECU receives a feedback signal sent from the energy storage battery ECU to obtain information of the second expected power.
In an embodiment of the invention, the expected power returns the SOC value of the energy storage battery to within a preset range. For example, the preset range is between 50% and 70% of the power when the energy storage battery is fully charged.
In the execution of the third step, the charging signal is adapted to cause the fuel cell to generate the output power provided to the energy storage battery, i.e. the fuel cell ECU will cause the fuel cell to generate the output power provided to the energy storage battery upon receiving the charging signal.
In an embodiment of the present invention, the fuel cell includes a fuel supply device (e.g., a fuel gas circulation pump), an air supply device (e.g., an air compressor), a cooling device (e.g., a cooling water circulation pump, a radiator), etc., which are required to operate normally in order for the fuel cell to generate output power. Thus, the output power provided by the fuel cell to the energy storage battery may include the auxiliary power required to operate the devices properly as well as the desired power output to the energy storage battery.
In the embodiment of the invention, the electric control ECU can display the related information for charging the energy storage battery through an instrument panel or a display screen, and can also provide the information in a voice mode, so that a user can timely acquire the information in the running process of the automobile, and the information can be used for determining whether the energy storage battery needs to be charged manually or timely knowing the related state of the automobile.
For example, a user may learn, through a dashboard, display, or voice, travel state information that is currently on start, acceleration, or climbing, and may determine whether the energy storage battery needs to be manually charged based on the information; the user may learn through a dashboard, display screen, or voice whether the real-time value of the SOC of the energy storage battery is always below the SOC threshold value, and may determine whether manual charging of the energy storage battery is required based on this information.
For another example, the user may learn feedback information about whether the energy storage battery is successfully charged manually, status information of the fuel cell, through a dashboard, a display screen, or voice, which helps the user determine whether further operations or maintenance are needed.
The embodiment of the invention also discloses a device for charging the energy storage battery of the fuel cell automobile, which can comprise a memory and a processor, wherein the memory stores computer instructions capable of running on the processor.
