Abstract
The utility model proposes a kind of battery leakage detection means, for detect in battery case battery whether leakage, including main control module, the balance module being connected with the main control module being arranged in battery case and the detection module being connected with the balance module by CAN lines being arranged in battery case, the detection module is hydrofluoric acid detection means.Battery leakage detection means of the present utility model, detects whether the content of hydrofluoric acid is exceeded and determines whether battery leakage by detection module, improves the security that battery is used.
Description
【Technical field】
The utility model is related to battery detecting field, more particularly to a kind of battery leakage detection means.
【Background technology】
Current battery management system BMS is to have monitored often to go here and there battery, it is impossible to accomplish to monitor each battery, but when single
There is leakage and without when replacing is processed in time in battery, the electrolyte for flowing out may corrode pcb board, cause the safety such as short circuit
Problem occurs.
【Utility model content】
The utility model technical problem to be solved is, for cannot be supervised to the leakage of single battery in the prior art
The technical problem of control proposes a kind of battery leakage detection means.
To achieve these goals, battery leakage detection means of the present utility model, for detecting that battery is in battery case
No leakage, specifically, including main control module, the balance module being connected with the main control module and the setting being arranged in battery case
The detection module being connected with the balance module by CAN lines in battery case, the detection module is that hydrofluoric acid detects dress
Put.
Improved as one kind of the utility model battery leakage detection means, the hydrofluoric acid detection means includes hydrofluoric acid
Sensor and CAN communication mouthful, the CAN communication mouthful connect the balance module, the hydrofluoric acid sensor by the CAN lines
For detecting the fluohydric acid content in battery case, and when the fluohydric acid content exceedes preset value, by the CAN communication mouthful
Leakage information is sent to the balance module, the balance module is by the leakage information transmission to main control module, main control module
Send leakage information warning.
Improved as one kind of the utility model battery leakage detection means, main control module also includes alarm module, is used for
Information warning is sent when main control module receives leakage information.
Improved as one kind of the utility model battery leakage detection means, the alarm module is buzzer, for sending out
Go out sound warning message.
Improved as one kind of the utility model battery leakage detection means, the alarm module is display screen, for showing
Show warning message.
The utility model produce beneficial effect be：Battery leakage detection means of the present utility model, by detection module
Detect whether the content of hydrofluoric acid is exceeded and determine whether battery leakage, improve the security that battery is used.
【Brief description of the drawings】
Fig. 1 is battery leakage structure of the detecting device schematic diagram of the present utility model；
Fig. 2 is detection module structural representation in Fig. 1.
【Specific embodiment】
In order that the purpose of this utility model, technical scheme and Advantageous Effects become apparent from understanding, below in conjunction with attached
Figure and specific embodiment, are further elaborated to the utility model.It should be appreciated that described in this specification
Specific embodiment is not intended to limit the utility model just for the sake of explaining the utility model.
Referring to Fig. 1 to Fig. 2, battery leakage detection means of the present utility model, for detecting whether battery leaks in battery case
Liquid, it is specific to include main control module 10, the balance module 20 being connected with the main control module 10 being arranged in battery case and set
The detection module 30 being connected with the balance module 20 by CAN lines in battery case is put, the detection module 30 is hydrogen fluorine
Sour detection means, specifically includes hydrofluoric acid sensor 31 and CAN communication mouthful 32, and the hydrofluoric acid sensor 31 is used to detect space
Interior fluohydric acid content, and when the fluohydric acid content exceedes preset value, leakage information is sent by the CAN communication mouthful 32
To the balance module 20, by the leakage information transmission to main control module 10, main control module 10 sends the balance module 20
Leakage information warning.
Battery electrolyte main matter is exactly lithium hexafluoro phosphate, and it meets water can produce the hydrofluoric acid, hydrofluoric acid to have volatility
And corrosivity, and have pungent smell, as long as battery leakage, the content of hydrofluoric acid will increase in air in battery case, this
The battery leakage detection means of utility model exactly detects whether hydrofluoric acid surpasses by hydrofluoric acid sensor 31 using this point
Mark to determine whether leakage, improve the security that battery is used.Battery leakage detection means of the present utility model mainly exists
Information transmission technique between the design of detection module 30, detection module 30, balance module 20 and main control module 10 can be adopted
Use prior art.
The main control module 10 also includes alarm module, for sending warning when main control module 10 receives leakage information
Information.Preferably, the alarm module is buzzer, for sending audible alarm information；Or the alarm module is display
Screen, for display alarm information.
Battery leakage detection means of the present utility model, is not restricted to described in specification and implementation method, because
This is easily achieved additional advantage and modification for the personnel of familiar field, therefore without departing substantially from claim and equally
In the case of the spirit and scope of the universal that scope is limited, the utility model is not limited to specific details, representativeness
Equipment and shown here as with description examples shown.
