Description
【Technical field】
It the utility model is related to battery technology field, and in particular to a kind of power battery pack.
【Background technology】
Energy storage component of the power battery pack as electric car, usually forms battery with many a single battery connection in series-parallel
Module, then battery modules are contained in Battery case and are fixed by Battery case and are equipped on electric car.In order to make battery
Module can be used safely and steady operation is, it is necessary to battery modules dustproof and waterproof, thus Battery case be designed to one it is close
The space closed, it is impossible to directly carry out heat exchange with extraneous.
Battery modules produce substantial amounts of heat in charge and discharge process, and common radiating mode is air cooling method, i.e., using fan
Strengthen inner air circulation, there is the advantages such as technique is simple, electrical security is high, cost is low.But during long-time use,
If being likely to occur the fan phenomenon problem fan either burnt out that comes off timely cannot be repaired or be replaced, heat dissipation effect
Fruit will substantially reduce, and cause battery modules constant temperature to increase and influence its service life, it is also possible to be arrived in BMS system detectios
Battery modules temperature automatically powers off when excessive, threatens the security of the lives and property.
In consideration of it, it is really necessary to provide a kind of power battery pack to overcome drawbacks described above.
【Utility model content】
The purpose of this utility model be to provide one kind can find in time for cooling fan whether occur it is abnormal so as to
Improve the power battery pack of security performance.
The utility model provides a kind of power battery pack, including Battery case, the battery that is contained in the Battery case
Module, at least one fan for strengthening the circulation of Battery case inner air, for detecting wind sense inside the Battery case
Sensor and the alarm of alarm can be sent；The fan is contained in the Battery case and is fixedly installed to described
Battery case；The sensor is contained in the Battery case and is fixedly attached to the Battery case or the battery mould
Group；The alarm can send reminder alarm when the sensor detects wind sense exception.
In a preferred embodiment, the quantity of the fan is multiple, between multiple fans are in the Battery case
Every distribution；The quantity of the sensor corresponds to the fan and multiple sensors are corresponded with multiple fans and are distributed.
In a preferred embodiment, the sensor is connected with the alarm by controller, the controller
Internal circuit be connected with the sensor and receive the signal of the sensor feedback, the internal circuit of the controller also with
The alarm is connected and controls whether the alarm sends alarm.
In a preferred embodiment, each sensor is used for the outlet air wind speed for detecting a corresponding fan, if outlet air
Wind speed is less than default air speed value, then the sensor detects wind sense exception.
In power battery pack provided by the utility model, when the situation that comes off or burn out occurs in the fan installed in Battery case
When, the wind sense that sensor detects can change and signal is fed back to control system makes alarm send alarm.Receive police
Fan is overhauled or replaced as early as possible after report, can be continued increase to avoid the temperature of battery modules or even be automatically powered off.This practicality is new
Type provide power battery pack not only increase security, also have the characteristics that it is simple in structure, occupy little space, cost it is low.
【Brief description of the drawings】
Fig. 1 is the functional block diagram of power battery pack provided by the utility model.
【Embodiment】
In order to make the purpose of this utility model, technical solution and advantageous effects become apparent from understanding, below in conjunction with attached
Figure and embodiment, are further elaborated the utility model.It should be appreciated that described in this specification
Embodiment is not intended to limit the utility model just for the sake of explaining the utility model.
Referring to Fig. 1, the utility model provides a kind of power battery pack 10, including Battery case 1, it is contained in the battery
It is battery modules 2 in babinet 1, at least one fan 3 for strengthening the circulation of 1 inner air of Battery case, described for detecting
The sensor 4 of 1 inside wind sense of Battery case and the alarm 5 that alarm can be sent.
Specifically, the fan 3 is contained in the Battery case 1 and is fixedly installed to the Battery case 1.The biography
Sensor 4 is contained in the Battery case 1 and is fixedly attached to the Battery case 1 or the battery modules 2.The alarm
Device 5 is connected with the sensor 4 and can send reminder alarm when the sensor 4 detects wind sense exception.
Further, the quantity of the fan 3 is multiple that multiple fans 3 are spaced apart in the Battery case 1, institute
The quantity for stating sensor 4 is corresponded with multiple fans 3 and is distributed corresponding to the fan 3 and multiple sensors 4.Each sensor
4 are used to detect the outlet air wind speed for corresponding to a fan 3, if outlet air wind speed is less than default air speed value, the sensor 4 detects
Wind sense is abnormal.
It should be understood that the power battery pack 10 further includes a controller 6, the sensor 4 is logical with the alarm 5
Cross the controller 6 to be connected, i.e., described sensor 4, the alarm 5 are connected with the controller 6 respectively.The controller
Circuit possessed by 6 can receive the signal that the sensor 4 is fed back, and in the 6 received signal of controller because described in
When 1 inside wind sense of Battery case changes and produces abnormal, the controller 6 makes the alarm 5 by certain circuit
Send alarm.
In power battery pack provided by the utility model, when the situation that comes off or burn out occurs in the fan installed in Battery case
When, the wind sense that neighbouring sensor detects can change and signal is fed back to control system makes alarm send alarm.Receive
Fan is overhauled or replaced as early as possible after to alarm, can be continued increase to avoid the temperature of battery modules or even be automatically powered off.This reality
Not only increase security with the power battery pack of new offer, also with it is simple in structure, occupy little space, the spy that cost is low
Point.
The utility model is not restricted to described in specification and embodiment, therefore for the personnel of familiar field
For additional advantage and modification is easily achieved, therefore in the universal limited without departing substantially from claim and equivalency range
Spirit and scope in the case of, the utility model is not limited to specific details, representational equipment and shown here as with retouching
The examples shown stated.
