Problems solved by technology

Although the performance of lithium-ion batteries is advanced, there are risks of thermal runaway, fire or even explosion due to overcharging, over-discharging, overloading and short-circuiting, aging, high temperature, impact, extrusion, etc.
Once a fire or other accident occurs in the lithium-ion battery compartment, if it cannot be extinguished in time, it will cause the ship's power source to fail, greatly reduce the navigation capability, and even cause damage to the ship and casualties. The loss is immeasurable

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0043]After ships and submersibles use lithium-ion power batteries as power sources, due to the liquid electrolyte lithium-ion power batteries may be abused by machinery, electricity and heat, the temperature will rise, triggering a thermal runaway chain reaction of lithium-ion batteries, and eventually leading to thermal runaway Therefore, security devices are required to centrally display the ...

Description

technical field [0001] The invention belongs to the field of ship power systems, and more specifically relates to a ship lithium-ion power battery safety guarantee system and method. Background technique [0002] As a new generation battery power source for ships, lithium-ion batteries can greatly improve the endurance of ships, and greatly promote the comprehensive combat capabilities such as improving the concealment of ships. Although the performance of lithium-ion batteries is advanced, there are risks of thermal runaway, fire or even explosion due to overcharging, over-discharging, overloading and short-circuiting, aging, excessive temperature, impact, extrusion, etc. Once a fire or other accident occurs in the lithium-ion battery compartment, if it cannot be extinguished in time, it will cause the ship's power source to fail, greatly reduce the navigation capability, and even cause damage to the ship and casualties. The loss is immeasurable. [0003] In view of the fa...
