Fire fighting system for battery charging and replacing station, fire fighting method and battery pack

Abstract

The invention discloses a fire fighting system for a battery charging and replacing station, a fire fighting method and a battery pack. The fire fighting system comprises a fire extinguishing device subsystem, a detection subsystem and a control subsystem. The fire extinguishing device subsystem comprises at least one fire extinguishing device; the detection subsystem is configured to obtain state parameter information of the battery pack and transmit the state parameter information to the control subsystem when detecting that the battery pack is connected to a charging interface; and the control subsystem is used for judging the state of the battery pack according to the state parameter information, and triggering a fire extinguishing device when judging that the battery pack is in a set fault state. The fire fighting system can obtain the state parameter information in the battery pack in real time, meanwhile, when the battery pack is in the fault state, the fire extinguishing device subsystem can directly conduct fire fighting treatment on the interior of the battery pack, the situation that nearby battery packs are involved is avoided, and the maintenance and operation cost in the battery charging and replacing station is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of fire protection, and in particular to a fire protection system, a fire protection method, and a battery pack for charging and swapping stations. Background technique [0002] With the advancement of battery swapping technology, charging and swapping stations, as one of the energy supply solutions for electric vehicles, have become more and more popular. [0003] Due to the high technical integration of the charging and swapping station, the fire safety hazard of the battery is increased during the frequent charging and swapping process. In the traditional fire control system of charging and swapping stations, the external fire extinguishing method is generally adopted. When a fire alarm is detected, the fire extinguishing device is directly turned on. [0004] However, for the fire inside the battery, the existing fire extinguishing methods cannot reach the fire core area of ​​t...

Problems solved by technology

[0004]However, for the fire inside the battery, the existing fire extinguishing methods cannot reach the fire core area of ​​the battery. When a fire occurs outside the battery, it will implicate nearby battery

At the same time, the fire extinguishing of the entire charging and swapping station will lead to an increase in fire extinguishing costs and a waste of fire extinguishing resources.
