Description
Technical Field
The invention relates to a fuel cell automobile and a fuel gas pressure maintaining and replacing control system thereof, belonging to the technical field of fuel gas pressure maintaining and replacing control in fuel cell automobiles.
Background
As the amount of fossil energy stored is decreasing, other types of power are becoming more and more important to the automotive industry, among which are fuel cells. Currently, fuel cell vehicles are increasingly used, particularly hydrogen fuel cell vehicles. As shown in fig. 1, a pipeline connection diagram of a hydrogen supply system of a hydrogen fuel cell automobile designed for our company comprises at least one gas storage bottle pipeline, all the gas storage bottle pipelines are connected with a main gas supply pipeline, the output ends of the gas storage bottles are respectively provided with a bottle opening combination valve 3 which comprises a bottle opening electromagnetic valve 3 (1), and the main gas supply pipeline is provided with an electromagnetic valve called a main electromagnetic valve 6. Other components in the hydrogen supply system are as follows: the device comprises a bottle tail PRD1, a gas bottle 2, an overflow valve 4, a filter 5, a pressure reducing valve 7, a ball valve 8, a one-way valve 9, a high-pressure gauge 10 and a hydrogenation port 11, wherein the output of the ball valve 8 is connected with a fuel cell 12.
Regardless of the fuel gas fuel cell vehicle, it is necessary to ensure that the fuel gas does not leak throughout the system operation. In the case of a hydrogen fuel cell passenger car, the hydrogen is required to be ensured not to leak in the operation of the whole system, so that a pressure-maintaining and leak-detecting experiment is required to be carried out before a new car system is tested, in the annual inspection process of the car or when the new car system is required to be tested, and a nitrogen and helium mixed gas which is not flammable and does not support combustion is injected into the hydrogen inlet system for pressure maintaining; after the system is determined not to leak, the mixed gas of nitrogen and helium in the system is replaced by hydrogen, so that the running test of the whole system or the operation of the vehicle can be formally started. For the whole vehicle, when the fuel cell is not started and serious faults or accidents occur on the vehicle, the whole vehicle is required to cut off the hydrogen fuel supply; hydrogen is normally supplied only during fuel cell operation or during shutdown purge. The pressure maintaining and replacement functions of the hydrogen system and the supply and cut-off functions of the hydrogen fuel relate to the power supply control problem of the bottleneck electromagnetic valve and the main electromagnetic valve. The working principle of the electromagnetic valve is as follows: the electromagnetic valve is powered on, and the corresponding electromagnetic valve is conducted; the electromagnetic valve is powered off, and the corresponding electromagnetic valve is turned off. Then, the power supply conditions of the bottleneck solenoid valve and the main solenoid valve are shown in table 1, wherein "valve" represents power supply, and "×" represents no power supply, and represents solenoid valve off.
TABLE 1
However, at present, no control device is provided for pressure maintaining and replacement of a hydrogen supply system, and at present, domestic hydrogen fuel cell buses are still in a research and demonstration operation stage, so that the problem of solenoid valve control in the pressure maintaining and replacement processes of fuel gas, especially hydrogen, is solved conveniently and rapidly.

Detailed Description
Fuel cell automobile embodiment
The present embodiment provides a fuel cell vehicle in which a fuel gas pressure maintaining and replacement control system for maintaining pressure and replacing fuel gas for the vehicle is provided. Since the fuel gas in the fuel cell is normally hydrogen gas, the fuel cell is exemplified as a hydrogen fuel cell in the present embodiment. Of course, the fuel gas pressure maintaining and replacing control system provided by the invention is not limited to the type of fuel gas, so that no matter what fuel gas is, the fuel gas pressure maintaining and replacing control system is within the protection scope of the invention.
As shown in fig. 2, the fuel gas pressure maintaining and replacement control system mainly includes the following portions: control signal output module, control module, first drive module and second drive module, control module sampling connection control signal output module, control connection first drive module and second drive module, wherein:
the control signal output module is used for outputting a pressure maintaining control signal or a replacement control signal, that is, the module can output the pressure maintaining control signal and the replacement control signal, and output the pressure maintaining control signal or the replacement control signal through switching, so the module can be a change-over switch or a device such as a selection switch, in this embodiment, the control signal output module is a rocker switch, and the rocker switch has three gears, namely a pressure maintaining gear, a replacement gear and a neutral gear, and outputs corresponding control signals through switching to a certain gear, for example: the rocker switch is switched to the pressure maintaining gear, and the rocker switch outputs a pressure maintaining control signal.
The control module is a control core of the system, and pressure maintaining and replacement control are realized through an internally loaded software program. The control module can adopt a specially arranged control chip, and can also adopt control equipment existing in the vehicle, such as a whole vehicle controller. In this embodiment, the control module is composed of a complete vehicle controller (HCU) and a hydrogen system controller (HMS), and pressure maintaining and replacement control are realized through the cooperation of the two controllers.
The first driving module is used for driving and controlling bottleneck electromagnetic valves arranged on the gas storage bottleneck, and when more than one gas storage bottle is arranged in the hydrogen supply system, the first driving module can simultaneously control all bottleneck electromagnetic valves, and the bottleneck electromagnetic valves are controlled to be turned on or turned off according to control signals of the control module; similarly, the second driving module is used for driving and controlling the main electromagnetic valve arranged on the air supply main pipeline, and controlling the on-off of the main electromagnetic valve according to the control signal of the control module.
Further, the system also comprises a state detection module for detecting whether the vehicle is in a high-voltage power-on state, and the control module is connected with the state detection module in a sampling way. In general, the vehicle cannot be powered on by high voltage electricity during the period of pressure maintaining or replacement, so the state detection module is arranged to detect the powered on state of the vehicle in real time, when the vehicle is in the powered on state, even if the pressure maintaining control signal or the replacement control signal is output by the control signal output module, the control module can not control to output the control command for controlling the conduction of the electromagnetic valve, and the instrument in the vehicle can also prompt that the pressure maintaining/replacement function is invalid and the high voltage is required to be powered down; also, when the worker forgets to restore the control signal output module to the initial state after the pressure maintaining and replacement are completed, the driver cannot put high pressure even if he has a driving demand.
Thus, based on the specific implementation of the components, this embodiment gives a specific structure of the control system, as shown in fig. 3.
The pressure maintaining/replacing rocker switch is connected with the HCU through a pressure maintaining and replacing signal transmission path and a hard wire output. The rocker switch has the following characteristics: the instrument desk is positioned on the instrument desk, so that the operation of a driver is facilitated; three gears (pressure maintaining, empty and replacement) exist, and the pressure maintaining and replacement switch is effective when the voltage of the external output pin of the replacement switch is 0V, and is ineffective when suspended. Wherein S1 is a hold pressure signal and S2 is a replacement signal.
The communication mode of the HCU, the HMS, the instrument and the vehicle-mounted terminal is CAN 2.0B, and the HCU is responsible for information interaction and control of the whole system, in particular: and S1, S2 signals, total fire and On fire power supply signals are collected in real time, control command interaction is carried out with the HMS according to the actual vehicle state, state information of the HMS and state information of the hydrogen bottleneck electromagnetic valve and the main electromagnetic valve are received, and vehicle state display is carried out by synchronizing an instrument. In addition, the vehicle-mounted terminal is responsible for detecting vehicle key data, and for the system, the monitored data cover: s1 and S2 states, command state information between the HCU and the HMS, power supply states of the hydrogen bottleneck electromagnetic valve and the main electromagnetic valve and the like. The power supply of the HCU and the instrument is provided by the total fire and the On fire together, and the power supply of the HMS and the vehicle-mounted terminal is provided by the total fire.
As shown in fig. 3, the first driving module and the second driving module are both electromagnetic valve control circuits, wherein the first driving module comprises a relay K1, the HMS is controlled to be connected with a control coil of the relay K1, and a normally open contact of the relay K1 is connected in series on a power supply loop of the hydrogen bottleneck electromagnetic valve; the second driving module comprises a relay K2, the HMS is in control connection with a control coil of the relay K2, and a normally open contact of the relay K2 is arranged on a power supply loop of the main electromagnetic valve in series. The control coils of the relays K1 and K2 are respectively controlled by high-side driving signals C1 and C2 output by the HMS, and after contacts of the relays K1 and K2 are closed, the solenoid valve of the hydrogen bottle mouth and the main solenoid valve are respectively powered, and the solenoid valve is conducted. In addition, status signals K1_Ack and K2_Ack of the hydrogen bottleneck electromagnetic valve and the main electromagnetic valve can be fed back to the HMS through hard wires, and the high level is effective and the suspension is ineffective.
Fig. 4 is a control strategy flow chart of the system. The HCU monitors the state of the vehicle dwell/displacement rocker switch in real time, and the vehicle dwell/displacement rocker switch not being depressed includes the following two conditions:
(1) The vehicle is switched from the pressure maintaining state or the replacement state to the initial state, at the moment, the HCU sends an initialization state command to the HMS, the HMS sends control output of C1=0 and C2=0, contacts of the control relays K1 and K2 are disconnected, the power supply of the hydrogen bottleneck electromagnetic valve and the main electromagnetic valve is cut off, and the electromagnetic valve is in a cut-off state, so that the safety of the vehicle is ensured.
(2) The vehicle is in a normal operation state, the control output of the HMS is influenced by whether the whole vehicle starts a fuel cell or not, if the fuel cell is started, the HCU sends a command of supplying hydrogen, the HMS sends a command of C1=1 and C2=1, contacts of the relays K1 and K2 are closed, the power supply of the solenoid valve at the hydrogen bottle mouth and the main solenoid valve is normal, the solenoid valve is in a conducting state, and the hydrogen can be normally supplied; on the contrary, when the fuel cell is closed or the whole vehicle has serious faults or accidents, the HCU sends a command for cutting off the hydrogen supply, the HMS sends a command of C1=0 and C2=0, the contacts of the control relays K1 and K2 are disconnected, the power supply of the solenoid valve of the hydrogen bottle mouth and the main solenoid valve is cut off, and the solenoid valve is in a cut-off state, so that the safety of the vehicle is ensured.
When the pressure maintaining/replacing rocker switch of the vehicle is pressed, the HCU firstly judges the high-pressure on-line state of the vehicle, and in the high-pressure on-line state, the HCU does not send a command for opening the electromagnetic valve to the HMS, and meanwhile, the instrument prompts that the pressure maintaining/replacing function is invalid, and the HCU firstly presses the high pressure to remind an operator to implement according to the correct steps; if the high voltage is not electrified, the HCU sends corresponding commands to the HMS according to different states of S1 and S2, and the HMS outputs different control signals according to the received commands. The HMS executes corresponding control output according to different received commands, and after the pressure maintaining command is received, the control output C1=0 and C2=1; after receiving the replacement command, controlling output c1=1, c2=1; the HMS feeds back K1_Ack and K2_Ack states to the HCU in real time. In addition, the HCU monitors the driving behavior of the driver in real time, and if the HMS state is pressure maintaining or replacement, even if the driver has high-pressure operation, the HCU controls the whole vehicle to prohibit the high-pressure operation so as to ensure the safety of the vehicle.
In addition, the HCU sends state information to the vehicle-mounted terminal through the CAN in real time in the process of executing system detection and control, and the vehicle-mounted terminal CAN inquire historical information. When the vehicle can not normally carry out pressure maintaining and replacement, the problem points can be positioned by analyzing the background monitoring data, so that the problem can be rapidly solved.
The system has the advantages of simple structure and reasonable design, improves the waste of software and hardware resources and human resources caused by the traditional operation method, improves the personal safety of personnel in the operation process, and has stronger practicability.
