Example 2
The environment perception function of the safety system needs 24 hours of operation, the energy consumption is large, in order to solve the problem that the system provides energy by who, a vehicle-mounted solar panel is introduced to supply power for the whole system, and additional energy consumption of newly-added equipment is not increased to a vehicle. At present, the relatively mature solar cell panel products on the market comprise two types, namely a traditional monocrystalline silicon solar panel and a semi-flexible monocrystalline silicon solar panel, and the latter is good in bending performance and more suitable for being used in a vehicle-mounted environment, so that the semi-flexible solar panel 3 is selected. The roof is covered with the semi-flexible solar panel 3, the generated electric quantity is stored by a solar panel matched battery, and the redundant electric quantity is directly charged into a vehicle-mounted storage battery and can be used for other vehicle-mounted power requirements such as illumination and the like.
In addition, the solar cell panel carries a battery, an additional power supply can be provided for various sensors, a double-circuit power supply is formed together with the vehicle-mounted storage battery, when one battery is damaged due to faults, the other battery can still provide electric energy for equipment of the safety system, and the operation reliability of the system is improved.
The area of the FCX-Clarity roof of the Honda hydrogen fuel cell automobile is about 3.25m2, and the area of the solar cell panel is taken as the area of the roof for subsequent energy balance analysis and calculation.
In a safety system, a pressure relief steering device and an alarm are started when a fire occurs, the energy consumption is negligible, and the energy consumption of equipment which needs to run for 24 hours is large, and the safety system comprises: three on-vehicle cameras, two infrared sensors in the car and six ultrasonic sensors. The power consumption of these devices is as follows:
(1) the rated power of the vehicle-mounted camera is 5w, and the built-in image processing chip is about 0.075 w.
(2) The infrared sensor has a power rating of 0.00036w (negligible).
(3) The rated power of the ultrasonic sensor is 0.01 w.
Calculated as follows: the total energy consumption of the equipment per day is about 1.32X 106J, which is equivalent to 0.36 kw.h.
Solar power supply amount analysis
The area of a monocrystalline silicon semi-flexible solar cell panel used in the system after the monocrystalline silicon semi-flexible solar cell panel is paved on the roof is 3.25m2, the photoelectric conversion efficiency eta 1 is between 15% and 18%, and the intermediate value eta 1 is 16.5% for calculation. By taking the sea city as an example, the solar radiation amount of each month in typical meteorological year in Shanghai is firstly inquired, then the solar panel power generation amount in the season with minimum radiation is calculated, and when the season power generation amount is larger than the power consumption of equipment, the solar panel power generation amount is considered to be satisfied all the year round. The season with the least solar radiation in Shanghai city is winter (12, 1 and 2 months), the total radiation quantity Wtotal in winter is 675MJ/m2, and the average radiation quantity W per day is 7.5MJ/m 2.
When the vehicle is parked and travels, the solar radiation is uncertain, the roof is shaded by shadows, and the radiation quantity which can be received by a solar panel of the roof is half of the theoretical value in one day (eta 2 is 0.5).
Therefore, the average solar panel generating capacity E in Shanghai city in winter is as follows: since E ═ W × a × η 1 × η 2 ═ 1.97 × 106J corresponds to 0.55kw · h and is larger than the facility power consumption amount by 0.36kw · h, energy autonomy can be realized all year round in the Shanghai region.
Example 3
In order to test how much degree the pressure release valve rotates in the pressure release process can reduce the catastrophic consequences to a greater extent, numerical simulation is carried out, when the TPRD leaks downwards vertically, the whole vehicle is surrounded by hydrogen flame, and a front-row driver and a rear-row passenger cannot escape, so that the experimental result is consistent with that of a Japanese automobile research institute. When the orientation of the TPRD is changed to be a 30-degree inclination angle at the back, the front row drivers can safely escape, but the rear row passengers are still surrounded by flames and are difficult to escape as can be seen from the figure. When the inclination angle of the TPRD is changed to 45 degrees, no hydrogen flame exists in the front door and the rear door, and a driver and passengers can escape smoothly, so that the degree of disastrous consequences is reduced to the minimum when the inclination angle is 45 degrees.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
