As shown in
The central control system controls the operation of the hydrogen fuel cell system and the driving-force control system, and receives feedback information from the hydrogen fuel cell system and the driving-force control system. The central control system includes a central control module, as well as a rear wheel lock, a hydrogen-storing container lock and front and rear lamps electrically connected to the central control module. The central control system is provided with the hydrogen-storing container lock that is electrically connected with the central control module, in this way when the hydrogen-storing container needs to be replaced, maintenance personnel can send an instruction of unlocking the hydrogen-storing container to the central control module through a mobile phone, so it is convenient for maintenance personnel to replace the hydrogen-storing container. The central control module is electrically connected to the hydrogen fuel cell system and the driving-force control system. The hydrogen energy-powered moped in this example controls the operation of the hydrogen fuel cell system and the driving-force control system through the central control system and enables the central control system to obtain the operation conditions of the entire moped in time by ways of transmitting the feedback information of the hydrogen fuel cell system and the driving-force control system to the central control system, so that the central control system can control the moped more rationally, thereby reducing maintenance costs and improving users' experience.
The hydrogen fuel cell system generates electric energy to supply electricity to the central control system, the driving-force control system and the lithium battery pack. The hydrogen fuel cell system includes a hydrogen-storing container (a hydrogen-storing tank/a hydrogen-storing bottle), an gas-in solenoid valve, a hydrogen fuel stack and an exhaust solenoid valve communicating with each other in proper order through a pipeline, a pressure transmitter arranged on the pipeline between the gas-in solenoid valve and the hydrogen fuel stack, a temperature sensor arranged on the hydrogen fuel stack, a heating module arranged outside the hydrogen-storing container, and a hydrogen fuel cell management module electrically connected to the gas-in solenoid valve, the hydrogen fuel stack, the exhaust solenoid valve, the pressure transmitter, the temperature sensor and the heating module. The hydrogen fuel cell management module is electrically connected to the central control system, the driving-force control system and the lithium battery pack. The main function of the hydrogen fuel cell management module is to collect information from the pressure transmitter and the temperature sensor, and control the operation of the gas-in solenoid valve, the hydrogen fuel stack, the exhaust solenoid valve and the heating module. The hydrogen fuel stack is designed to generate electrical energy that is delivered to the central control system, the driving-force control system and the lithium battery pack through the fuel cell management module, so this design can improve the rationality of managing electrical energy and avoid wasting energy. The pressure transmitter is arranged on the pipeline between the gas-in solenoid valve and the hydrogen fuel stack, in this way when the gas-in pressure of the hydrogen fuel stack is insufficient, maintenance personnel can be notified in time to replace the hydrogen-storing container and turn off the hydrogen fuel stack without delay. The temperature sensor is set on the hydrogen fuel stack, in this way when the temperature of the hydrogen fuel stack is low, the information is fed back to the central control system, so that the central control system knows that the hydrogen fuel stack cannot start at this time, so as to avoid adverse effects on the service life of the hydrogen fuel stack. The heating module is set outside the hydrogen-storing container, so as to avoid occurrence of disenabling release of the hydrogen in the hydrogen-storing container in low temperature weather.
The driving-force control system controls the driving speed, and the lithium battery pack supplies electricity to the central control system and the driving-force control system. The driving-force control system includes an electric motor controller, and left and right brake handles, a power-assisted sensor and a driving motor electrically connected to the electric motor controller. The electric motor controller is electrically connected to the central control system, the hydrogen fuel cell system and the lithium battery pack. The main function of the electric motor controller is to receive signals from the left and right brake handles and the power-assisted sensor, drive the driving motor to rotate, and control the rotary speed of the driving motor. The power-assisted sensor electrically connected to the electric motor controller is set to facilitate the system to assist in controlling the rotary speed of the driving motor and improves safety performance.
As shown in
Compared with Example 1, this example mainly has three changes.
The hydrogen energy-powered moped in this example includes an energy system, and the management method for this energy system includes the management at the time of an user renting a moped, the management at the time of an users returning a moped, and the management at the time of a moped lying in the state of waiting for rent.
When an user rents the moped, the central control system unlocks the rear wheel lock and turns on the front and rear lamps, and sends an instruction of power-up to the hydrogen fuel cell management system and the electric motor controller, and the hydrogen fuel cell management system starts the hydrogen fuel stack; the process of starting the hydrogen fuel stack is specifically as follows: after the hydrogen fuel cell management system receives an instruction of power-up, it first detects the pressure of the hydrogen-storing container through the pressure transmitter, and detects the temperature of the hydrogen fuel stack through the temperature sensor; if the pressure of the hydrogen-storing container or the temperature of the hydrogen fuel stack does not meet the requirements, the hydrogen fuel cell management system will not start the hydrogen fuel stack and concurrently uploads fault information to the central control system; if the pressure of the hydrogen-storing container and the temperature of the hydrogen fuel stack both meet the requirements, then the hydrogen fuel cell management system starts the hydrogen fuel stack and opens the gas-in solenoid valve and the heating module of the hydrogen fuel stack, so as to ensure users smooth riding, avoid a midway power break and improve safety.
During the operation process of the hydrogen fuel stack, the hydrogen fuel cell management system adjusts the rotary speed of the fan of the hydrogen fuel stack and the exhaust frequency of the exhaust solenoid valve according to the temperature sensor and the output power of the hydrogen fuel stack, not only guaranteeing the efficiency of the hydrogen fuel stack, but also improving safety.
When an user returns the moped, the central control system locks the rear wheel lock and turns off the front and rear lamps, and sends an instruction of power-off to the hydrogen fuel cell management system and the electric motor controller, so as to cut the power supply to the electric motor controller, the hydrogen fuel stack and the hydrogen fuel cell management system; specifically, after the hydrogen fuel cell management system receives an instruction of power-off, it first detects the residual power of the lithium battery pack; if the residual power of the lithium battery pack is greater than a preset value, the hydrogen fuel cell management system turns off the hydrogen fuel stack; if the residual power of the lithium battery pack is less than a preset value, the hydrogen fuel stack will continue to operate and charge the lithium battery pack until the lithium battery pack gets fully charged, then the hydrogen fuel cell management system cuts the power supply to the hydrogen fuel stack and itself, so as to ensure that the lithium battery pack has sufficient power.
When the moped lies in the state of waiting for rent, the central control system determines whether to charge the lithium battery pack based on the residual power of the lithium battery pack, and determines whether to replace the hydrogen-storing container based on the internal pressure of the hydrogen-storing container. The process of the central control system determining whether to charge the lithium battery pack based on the residual power of the lithium battery pack is specifically as follows: the central control system evokes the hydrogen fuel cell management system every once in a while, the hydrogen fuel cell management system detects the residual power of the lithium battery pack after it has been evoked; if the residual power of the lithium battery pack is greater than a preset value, the hydrogen fuel cell management system turns off the hydrogen fuel stack; if the residual power of the lithium battery pack is less than a preset value, the hydrogen fuel stack will continue to operate and charge the lithium battery pack until the lithium battery pack gets fully charged, then the hydrogen fuel cell management system cuts the power supply to the hydrogen fuel stack and itself, this operation mode can not only reduce standby power consumption, but also ensure that the lithium battery pack has sufficient power at the time of an user renting a moped next time.
The process of the central control system determining whether to replace the hydrogen-storing container based on the internal pressure of the hydrogen-storing container is specifically as follows: the central control system evokes the hydrogen fuel cell management system every once in a while, and sends an instruction to inquire about the residual gas volume to the hydrogen fuel cell management system, after the hydrogen fuel cell management system has been evoked, it detects the pressure of the hydrogen-storing container through the pressure transmitter, when the internal pressure of the hydrogen-storing container is lower than a preset value, the central control system notifies maintenance personnel to replace the hydrogen-storing container through a background system. That is, the central control system sends the information about needing to replace the hydrogen-storing container, after the background system receives the information; it sends the information about the replacement of the hydrogen-storing container downwards to the mobile phone of maintenance personnel near the hydrogen-storing container. Then maintenance personnel send an unlocking instruction to the central control system through a mobile phone, after the central control system receives the instruction, it will unlock the hydrogen-storing container lock, and maintenance personnel will lock the hydrogen-storing container lock after replacing the hydrogen-storing container, concurrently send the information about having replaced the hydrogen-storing container to the background system, after the background system receives it, the system updates the information of the vehicle where the hydrogen-storing container is located, and refreshes the information about the vehicle's range. In this way, it can ensure that maintenance personnel replace the hydrogen-staring container in time, avoids occurrence of lacking gas in the hydrogen-staring container during an user using a rented moped, and improves users' experience.
In this example, the energy system management method of a hydrogen energy-powered moped is divided into three parts: the management at the time of an user renting a moped, the management at the time of an users returning a moped, and the management at the time of a moped lying in the state of waiting for rent, which greatly enhance the rationality of managing the energy system, ensure users a smooth progress for use, greatly enhance users' experience, and strongly promote the development of the hydrogen energy-powered moped.
As described in the above specific examples, the objective, the technical solution and the beneficial effect of the present invention are further described in detail. It should be understood that the above description are only specific examples of the present invention, not used to limit the present invention. Any modification, equivalent replacement, improvement and the likes made within the essence and principle of the present invention shall fall within the protection scope of the present invention.
