Set #1, #2, #3 ..., #N, altogether N number of second pin interface 131.Specifically, as shown in Figure 1, #1 second pin interface 131 connects
The status information (such as temperature information) that the first pin interface of #1 111 exports is received, meanwhile, #1 second pin interface 131 receives outside
The control instruction for controlling function corresponding with the status information that first pin interface of #1 111 is transmitted of input is (as schemed
Temperature control instruction).For example, the first pin interface of #1 111 exports the temperature information of battery pack 12, and connect by #1 second pin
Mouthfuls 131 outputs are to external equipment, and when needing to issue externally input temperature control instruction, which passes through #1 the
The access of two pin interfaces 131, and it is transmitted to the first pin interface of #1 111, protection board 11 is accessed by the first pin interface of #1 111；
For another example, the first pin interface of #2 111 exports the information of voltage of battery pack 12, and by the output of #2 second pin interface 131 to outer
Portion's equipment, when needing to issue externally input voltage control instructions, which passes through #2 second pin interface 131
Access, and it is transmitted to the first pin interface of #2 111, protection board 11 is accessed by the first pin interface of #2 111.
The present invention has the function of the protection board 11 of Data Analysis Services and control function by the way that this is arranged, and may be implemented in electricity
Pond group 12 when the temperature is excessively high, controls charge switch 114 and discharge switch 115 disconnects, and restore in 12 temperature of battery pack to normal
After range, control charge switch 114 be connected to discharge switch 115, to avoid abnormal conditions generation, as battery pack 12 burn or
Explosion etc. can also realize that, when the voltage of battery pack 12 is lower than low pressure threshold voltage, control discharge switch 115 disconnects, and
Discharge switch 115 is controlled when the voltage of battery pack 12 restores to normal range (NR) to be connected to；Alternatively, the voltage in battery pack 12 is higher than
When HVT high voltage threshold's voltage, control charge switch 114 is disconnected, and controls and put when the voltage of battery pack 12 restores to normal range (NR)
Electric switch 115 is connected to；So as to preferably avoid battery pack 12 under over-discharge or overcharge conditions, battery pack 12 is caused in itself
Damage problem, can effectively extend the service life of battery pack 12.By controlling above, protection board 11 of the invention makes electricity
Pond group 12 has the function of automatic Restoration Mechanism, brings better usage experience to user, prevents application apparatus (such as electronic
Vehicle) occur unnecessary phenomenon of casting anchor in use.
Further, the present invention can realize the shape to battery pack 12 using the protection board 11 by lower-cost mode
State information carries out real-time monitoring and state control, and is existed using the first pin interface 111 being arranged on protection board 11 and setting
Second pin interface 131 corresponding with the first pin interface 111 in communication module 13, can be by the collected state of protection board 11
Information is sent to communication module 13, and is being received by communication module 13 by the first pin interface 111, second pin interface 131
While to status information, sending status information to intelligent terminal, perhaps server keeps user or manager more preferable
Understanding battery pack 12 state, maintenance personal can determine the abnormal problem of battery pack 12 faster.
In addition, user or manager can issue external control instruction to communicating mould by intelligent terminal or server
External control instruction is sent to protection board by second pin interface 131, the first pin interface 111 by block 13, communication module 13
11, it is disconnected by protection board 11 according to the external control instruction control charge switch 114 and/or discharge switch 115 that issue, connection.
In the case where battery pack 12 or stolen electric vehicle, controlled by the charge switch 114 and discharge switch 115 that control battery pack 12
The state of battery pack 12 can achieve the purpose for reducing loss as far as possible.The present invention can be thus achieved using the protection board 11
Multi-faceted monitoring and control to battery pack 12, preferably to avoid abnormal conditions, and the power supply of protection board 11 is automatic
Restoration Mechanism can also bring better experience effect to user.
Further, the present invention also provides a kind of battery pack monitoring method, which be can be applied to
Batteries monitoring system provided in an embodiment of the present invention.
