example 1

[0017] The battery compartment can be cut off for the application of lithium-ion electric boats. Such as figure 1 , the battery compartment (3) can be cut off and installed at the bottom of the lithium-ion electric boat (1). Made of steel, keep a certain distance between the battery compartments to ensure that the fire battery will not immediately transfer a large amount of heat to the adjacent battery compartments. The connecting parts are made of lead-tin alloy with a melting point of 200°C. The cabin is fully submerged below the waterline (2). When the temperature of a connecting part of the battery compartment exceeds 150°C, the tensile strength of the connecting part drops sharply. Under the action of gravity of the heavy battery compartment, the connecting part is automatically pulled off, and the battery compartment and the main body are quickly separated. The separated battery compartment It includes not only the fire battery compartment, but also the adjacent affect...

example 2

[0019] The cut-off battery compartment is used in lithium-ion electric aircraft. The two cut-off battery compartments are respectively installed on the nose (10) and the tail (11). The cabin is made of flame-retardant fiberglass, the connecting parts are made of electromagnets, the control components are temperature control and smoke sensors that operate at 130°C, and each battery cabin is also equipped with a rocket ejection transposer. When the temperature of two sensors in the battery compartment exceeds 130°C, the electromagnetic connector connects the reverse current, the electromagnetic force reverses, and the battery compartment is expelled from the body. If it is stuck, the rocket ejection device can be activated after manual confirmation of the fire. Pop the battery compartment out of the body. Keep the extended distance between the battery compartment and the aircraft body after separate contact and connection to ensure the fire safety distance, and maintain the exte...

Abstract

According to the characteristics of electric cruise ships and airplanes, a method and device for disconnecting independent battery compartments to ensure fire safety are invented. The main features are as follows: first: more than one battery compartment is installed, which are respectively arranged in the left, middle and right areas of the bottom of the ship. It can be selectively disconnected, and the safe battery compartment remains on the main body to provide power. Second, the extension connection is adopted. When a danger occurs, the battery compartment is separated, and a safe distance is maintained between the extension and the hull, and the power supply is continued.

Description

technical field [0001] The invention relates to fire extinguishing technology and equipment for ships, airplanes and automobiles, and belongs to the technical fields of energy, transportation and fire safety. Background technique [0002] The 2020s is the era of batteries. With the development of various hybrid vehicles, the requirements for the safety performance of batteries are getting higher and higher. In particular, plug-in hybrid electric vehicles (PHEV), electric vehicles (EV) and electric boats have higher requirements. According to the highest safety standard in the industry, the quality control rate of 18650 batteries is calculated at 2ppm (a famous electric vehicle in the United States). Of the 100,000 cars sold, 1,600 have a high risk of spontaneous combustion. [0003] In addition to the characteristics of small size and light weight, lithium-ion batteries have a nominal voltage as high as 3.6 volts and a high energy density. But the lithium battery itself is...
