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

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...
