可选的,上述各个实施例中燃料电池系统1与储能系统2通过电缆7连接,其中,电缆7包括用于电能传递的高压电缆7和用于控制信号传递的低压电缆7。高压电缆用于各设备间电能的传递,低压电缆用于各设备控制信号的传递。由于现有的储能车需要在进站时,短时间内补充电能,因此其电缆的载流能力要求高,对应的电缆截面积也较大。采用燃料电池系统1供电后,其在车辆运行过程中一直处于发电状态,功率基本恒定,因此电缆的载流能力要求低,其对应的电缆截面积也较小,所以上述不同位置可选用不同类型的电缆。Alternatively, in each of the above embodiments, the fuel cell system 1 and the energy storage system 2 are connected by a cable 7, wherein the cable 7 includes a high voltage cable 7 for power transfer and a low voltage cable 7 for controlling signal transmission. High-voltage cables are used for the transmission of electrical energy between devices, and low-voltage cables are used for the transmission of control signals from various devices. Since the existing energy storage vehicle needs to replenish electric energy in a short time when entering the station, the current carrying capacity of the cable is required to be high, and the corresponding cable cross-sectional area is also large. After the fuel cell system 1 is powered, it is always in the power generation state during the running of the vehicle, and the power is basically constant, so the current carrying capacity of the cable is low, and the corresponding cable cross-sectional area is also small, so different types can be selected for the different positions. Cable.
可选的,上述燃料箱10的加注口需要满足燃料箱10的加注需求,例如,加注口可以满足5分钟内加满燃料箱10。当本发明用于无轨储能车辆时,根据车辆一天运行的里程,一天所需的燃料容积在300L左右,因此燃料箱的容积为300L,其加注口可以满足5分钟内加满燃料。Optionally, the filling port of the fuel tank 10 needs to meet the filling requirement of the fuel tank 10. For example, the filling port can satisfy the filling of the fuel tank 10 within 5 minutes. When the present invention is applied to a trackless energy storage vehicle, according to the mileage of the vehicle running one day, the fuel volume required for one day is about 300L, so the volume of the fuel tank is 300L, and the filling port can satisfy the filling of fuel within 5 minutes.
