Uniform all standing, while can also realize the accurate fire extinguishing too high to possessing temperature.
Dividing plate (8) is provided with the inwall of the casing (1), the casing (1) is divided into independent by the dividing plate (8)
Battery modules installation cavity.Each battery modules installation cavity is separate, complementation interference, can when a battery pack is on fire wherein
Other battery packs are effectively protected, more securely and reliably.
The fire suppression mechanism (3) is installed on the dividing plate (8), it is easy for installation, it is connected firmly.
The output end of the battery management system (6) is also connected with major loop electromagnetic coil relay.The condition of a fire is occurring
When, control signal, cut-out battery modules output can be sent.
A kind of echelon of automatic fire extinguisher utilizes the control method of battery bag, concretely comprises the following steps：
Step 1：Battery management system receives temperature sensor, either the number of Smoke Sensor or pressure sensor
According to；
Step 2：Judge whether data exceed setting value, more than then into next step；
Step 3：Exceeded sensing station, and being located at according to sensor are identified, is started nearest from the exceeded sensor
Fire extinguishing jet；
Step 4：Start all fire extinguishing jets and carry out ejecting extinguishing.
Beneficial effects of the present invention are：1. temperature sensor, Smoke Sensor and pressure sensing are set in battery modules
Device, battery modules temperature it is too high, it is on fire, deformed by severe crush when, automatically starting fire suppression mechanism cooled or
Fire extinguishing, the generation of danger is prevented, ensure that the security that retired echelon battery reuses；2. the extinguishing chemical in fire suppression mechanism
Storage housing sets jet and connection playpipe respectively on its table wall, the jet on table wall can rapid large-area injection,
Whole battery modules can be covered in the shortest time, playpipe can be realized to be carried out in fixed-point set to the too high region of temperature or point of origin
Injection, fire extinguishing is quicker, the expansion for the area that effectively prevents from catching fire.
