Embodiment, the present invention will be described in further detail.It should be appreciated that the specific implementation described in this specification
Mode is not intended to limit the present invention just for the sake of explaining the present invention.
Referring to Fig. 1, the present invention provides a kind of battery case security system 100, including battery management system 10, battery case
20th, battery case contactor 30, baroceptor 40 and display 50.The battery case contactor 30 respectively with the battery
Management system 10 and the battery case 20 are connected.The baroceptor 40 is connected by communication with the battery management system 10, institute
Baroceptor 40 is stated to be arranged in the battery case 20 and for gathering the atmospheric pressure value in the battery case 20.The display
50 are connected by communication with the battery management system 10, and warning lamp is provided with the display 50.
In the present embodiment, the battery management system 10 can gather in real time air pressure in the battery case 20, voltage,
The data such as electric current and temperature.The battery management system 10 includes multiple modules and multiple modules are stored in holder 60 simultaneously
A processor 70 is configured to perform, multiple modules, which can be independently arranged, also to become one.
Multiple modules include but is not limited to air pressure acquisition module 101, gas leakage judge module 102, analysis module 103,
Instruction sending module 104 and early warning sending module 105.
The air pressure acquisition module 101, for gathering the atmospheric pressure value of the baroceptor 40.
The gas leakage judge module 102, for judge the battery case 20 whether gas leakage.
The analysis module 103, for judging whether the atmospheric pressure value is more than default safety value.
The instruction sending module 104, disconnect electricity to the battery case contactor 30 for sending disconnecting circuit and instructing
Road.
The early warning sending module 105, for sending pre-warning signal to the display 50.
Referring to Fig. 2, a kind of control method for battery case security system 100 that the present invention also provides, comprises the following steps：
Step S01, the air pressure acquisition module 101 gather the atmospheric pressure value of the baroceptor 40；Perform step S02.
Step S02, the gas leakage judge module 102 judge the battery case 20 whether gas leakage；When the battery case 20 leaks
During gas, step S04 is performed；When state battery case 20 it is air tight when, perform step S03.
Specifically, the gas leakage judge module 102 judges whether the method for gas leakage includes the battery case 20：When by described
Atmospheric pressure value decline in a default time interval caused by air pressure difference be more than a preset pressure difference, then judge the electricity
The gas leakage of pond case 20；The air pressure difference caused by declined as the atmospheric pressure value in the default time interval is less than or equal to
The preset pressure difference, then judge that the battery case 20 is air tight.
When the battery case 20 starts to discharge, heat is produced, the gas in the battery case 20 can be with battery temperature liter
It is high and be heated, so as to cause gas expansion, therefore, the air pressure rising in the battery case 20.When the battery case 20 occurs
When aging occur in crack or seal, the process drastically declined again after rising occurs in the air pressure in the battery case 20.
