Embodiment

[0065] Embodiment: refer to attached Figure 1-9 , to more fully describe the embodiments of the present invention, however, the accompanying drawings are only for illustration and illustration, and are not intended to limit the scope of the present invention.

[0066] According to the project example analysis: a typical car-passenger ferry has a length of about 127 meters, a molded width of 103 about 20.4 meters, a design draft of about 4.2 meters, and a molded depth of about 6.3 meters. The distance 204 between the inner hull and the hull is ≥B / 5 (about 4.08m). The total battery capacity is about 72,000kWh, and the cruising power is about 320n.mi leˉ600km at a speed of 16kn. A full charge can satisfy 12 round trips between the Qiongzhou Strait.

Abstract

The invention relates to a pure electric vehicle passenger ferry with large-capacity batteries, which comprises a ship structure with the large-capacity batteries, the large-capacity power batteries are dispersed according to the capacity and are arranged in double shells of the ship in different areas, and a battery cabin adopts a redundant structure and is used for reducing the accident rate of the batteries and improving the survival probability of the ship after being damaged; a protection system of a high-capacity battery is used for protection of a high-capacity battery structure before an accident, guarantee of environmental conditions and safety monitoring during operation, fire protection of the battery and prevention of leakage of harmful substances of the battery. The cruising ability of the pure electric power ship is improved. The problems that a pure electric power ship is short in endurance, small in vehicle loading space, high in operation and storage safety and high in accident rate are solved. The method is not only suitable for vehicle and passenger ferries between straits and ferries on both sides of a river, but also suitable for ro-ro passenger ships or ships in similar structural forms and other hybrid power ships and bidirectional sailing ships containing batteries, and is a key technology for ensuring the economy of the ship type and the safety of the batteries.

Description

technical field [0001] The invention relates to a pure electric car-passenger ferry, in particular to a car-passenger ferry with a large-capacity battery as the propelling power. Background technique [0002] The Qiongzhou Strait is a golden waterway connecting Hainan and the mainland of the motherland. With the integration of the Greater Bay Area and the construction of the Hainan International Free Trade Zone, the traffic between the straits has become increasingly busy. However, the current fuel-powered car-passenger ferry is still the main type of ship, and its carbon, nitrogen, and sulfur emissions are unavoidable. With batteries as the power source, the ship has the advantage of zero emission of pollutants when it is working, and it has received more and more attention. [0003] However, the disadvantages of batteries are also obvious. In order to improve the endurance, a large-capacity battery needs to occupy a large amount of space on the ship. If the vehicle comp...
